Syed MA , Siddiqui MI , Memon IH , Jehandad K , Baloch NN , Jamal H , Hussain A , Memon NM , Syed MH , Ahmed ZA , Fontaine RE , Rullán-Oliver P . Int J Infect Dis 2024 146 107141 OBJECTIVES: In Sindh Province, Pakistan, confirmed Crimean-Congo haemorrhagic fever (CCHF) increased from zero in 2008 to 16 in 2015-2016. To counter this increase, in 2016, we initiated structured CCHF surveillance to improve estimates of risk factors for CCHF in Sindh and to identify potential interventions. METHODS: Beginning in 2016, all referral hospitals in Sindh reported all CCHF cases to surveillance agents. We used laboratory-confirmed cases from CCHF surveillance from 2016 to 2020 to compute incidence rates and in a case-control study to quantify risk factors for CCHF. RESULTS: For the 5 years, CCHF incidence was 4.2 per million for the Sindh capital, Karachi, (68 cases) and 0.4 per million elsewhere. Each year, the onset of new cases peaked during the 13 days during and after the 3-day Eid-al-Adha festival, when Muslims sacrificed livestock, accounting for 38% of cases. In Karachi, livestock for Eid were purchased at a seasonal livestock market that concentrated up to 700,000 livestock. CCHF cases were most common (44%) among the general population that had visited livestock markets (odds ratio = 102). CONCLUSIONS: Urban CCHF in Sindh province is associated with the general public's exposure to livestock markets in addition to high-risk occupations. |
Impact of race-free glomerular filtration rate estimations on CKD prevalence in the US military health system: A retrospective cohort study
Oliver JD , Nee R , Marneweck H , Banaag A , Koyama AK , Pavkov ME , Koehlmoos TP . Kidney Med 2024 6 (8) Rationale & Objective: The 2021 CKD-EPI removes Black race as a factor in calculating the estimated glomerular filtration rate (eGFR). We assessed its effect on CKD prevalence in the demographically-diverse US Military Health System. Study Design: A retrospective calculation of the eGFR from serum creatinine measured over 2016-2019 using both the 2009 and 2021 CKD-EPI equations. Setting & Population: Multicenter health care network with data from 1,502,607 adults in the complete case analysis and from 1,970,433 adults in an imputed race analysis. Predictors: Serum creatinine, age, sex, and race. Outcome: CKD stages 3-5, defined as the last eGFR persistently < 60 mL/min/1.73m2 for ≥90 days. Analytical Approach: The t test and Kruskal-Wallis test were used for continuous variables and Χ2 for categorical data. Results: The population in the complete case analysis had a median age of 40 years and was 18.8% Black race and 35.4% female. With the 2021 equation, the number of Black adults with CKD stages 3-5 increased by 58.1% from 4,147 to 6,556, a change in the crude prevalence from 1.47% to 2.32%. The number of non-Black adults with CKD stages 3-5 decreased by 30.4% from 27,596 to 19,213, a crude prevalence change from 2.26% to 1.58%. Similar results were seen with race imputation. Cumulatively, among adults with CKD stages 3-5 by at least one equation, 45.8% of Black adults were reclassified to more advanced stages of CKD and 44.0% of non-Black adults were reclassified to less severe stages across eGFR thresholds that could change clinical management. Limitations: Potential underestimation of CKD in individuals with only 1 measurement. Conclusions: Adoption of the 2021 CKD-EPI equation in the Military Health System reclassifies many Black adults into new CKD stages 3-5 or into more advanced CKD stages, with the opposite effect on non-Black adults. This may have an effect on CKD treatment and outcomes in ways that are yet unknown. Plain-Language Summary: Until recently, kidney function level was calculated from equations that adjusted the result if the individual was of Black race. Because this may contribute to racial disparities in kidney disease care, a new equation was developed in 2021 that excludes race as a factor. We assessed the possible effects of this equation using data from adults in the US Military Health System from 2016 to 2019. With the new equation, the number of Black adults classified with kidney disease increased while that of non-Black adults decreased. There were similar trends seen in the more severe levels of kidney disease, which could affect decisions in clinical care. These results emphasize the potential positive and negative outcomes to be monitored with the new equation. © 2024 The Authors |
Characteristics of reported mumps cases in the United States: 2018-2023
Tappe J , Leung J , Mathis AD , Oliver SE , Masters NB . Vaccine 2024 BACKGROUND: This paper highlights recent clinical complications of mumps reported in the United States and summarizes appropriate confirmatory testing for mumps, encouraging vigilance for mumps disease, an endemic vaccine-preventable illness. METHODS: Surveillance data from jurisdictions reporting confirmed and probable cases of mumps in the United States were descriptively analyzed to assess epidemiologic trends from January 1, 2018 - December 31, 2023. Data were reported to the National Notifiable Disease Surveillance System and the Epidemiology and Laboratory Capacity Project O. Cases were classified according to the Council of State and Territorial Epidemiologists 2011 mumps case definition. RESULTS: From 2018-2023, United States health departments reported 8,006 confirmed and probable mumps cases to the National Notifiable Disease Surveillance System, of which 85.4% occurred during January 1, 2018-April 4, 2020 and 14.6% during April 5, 2020-December 31, 2023. The incidence of mumps was highest among those aged 18-24 years during 2018-2020 (maximum of 4.54 cases per 100,000 persons in 2019), and highest among those aged 1-4 years during 2021-2023 (maximum 0.67 per 100,000 persons in 2023). Incidence among all age groups during 2021-2023 remained below levels during 2018-2020. Fewer than 12% of mumps cases were confirmed during 2021-2023, compared to >50% during 2018-2019. CONCLUSIONS: Although incidence has declined since the COVID-19 pandemic, these surveillance data highlight that mumps remains endemic in the United States. Therefore, maintaining high MMR vaccination coverage is essential to prevent future vaccine-preventable outbreaks and minimize severe complications from infection. |
Real-time use of a dynamic model to measure the impact of public health interventions on measles outbreak size and duration - Chicago, Illinois, 2024
Masters NB , Holmdahl I , Miller PB , Kumar CK , Herzog CM , DeJonge PM , Gretsch S , Oliver SE , Patel M , Sugerman DE , Bruce BB , Borah BF , Olesen SW . MMWR Morb Mortal Wkly Rep 2024 73 (19) 430-434 Measles is a highly infectious, vaccine-preventable disease that can cause severe illness, hospitalization, and death. A measles outbreak associated with a migrant shelter in Chicago occurred during February-April 2024, in which a total of 57 confirmed cases were identified, including 52 among shelter residents, three among staff members, and two among community members with a known link to the shelter. CDC simulated a measles outbreak among shelter residents using a dynamic disease model, updated in real time as additional cases were identified, to produce outbreak forecasts and assess the impact of public health interventions. As of April 8, the model forecasted a median final outbreak size of 58 cases (IQR = 56-60 cases); model fit and prediction range improved as more case data became available. Counterfactual analysis of different intervention scenarios demonstrated the importance of early deployment of public health interventions in Chicago, with a 69% chance of an outbreak of 100 or more cases had there been no mass vaccination or active case-finding compared with only a 1% chance when those interventions were deployed. This analysis highlights the value of using real-time, dynamic models to aid public health response, set expectations about outbreak size and duration, and quantify the impact of interventions. The model shows that prompt mass vaccination and active case-finding likely substantially reduced the chance of a large (100 or more cases) outbreak in Chicago. |
Assessment of the standardized surveillance case definition for neonatal abstinence syndrome by the Council Of State and Territorial Epidemiologists, 4 jurisdictions, 2020-2021
Czarnik M , Oliver D , Goodson V , Nestoridi E , Michael Bryan J , Hinds D , Clark C , Green C , Small J , Pabst L . Public Health Rep 2024 Objectives: In 2019, the Council of State and Territorial Epidemiologists ratified a multitiered standardized surveillance case definition (SSCD) for neonatal abstinence syndrome (NAS) to minimize variability in definitions across states. This evaluation of the tier 1 NAS SSCD aimed to identify common challenges and opportunities for enhancement to support consistent implementation of the definition. Methods: This mixed-methods analysis consisted of 3 virtual focus groups in March 2021 with site principal investigators, medical record abstractors, and data analysts (1 focus group each) from 4 jurisdictions piloting the tier 1 NAS SSCD. We analyzed focus group transcripts to create a codebook. We collected written reports in February 2022 from the 4 jurisdictions, conducted thematic analysis of focus group transcripts and written reports to identify themes, and collected surveillance data on infants identified with NAS born from January 2020 through December 2021 from the pilot sites. We analyzed surveillance data to further inform identified themes. We examined agreement among tier 1 classifications assigned independently by each pilot site and the Centers for Disease Control and Prevention to cases of NAS. Results: Three major themes emerged in the data: challenges abstracting data on withdrawal signs from the medical record, difficulty determining the time frame of prenatal substance exposure, and challenges assigning case classifications. In a comparison of tier 1 classifications assigned by the Centers for Disease Control and Prevention and the sites, 82.1% of cases in the dataset were concordant. Conclusions: We identified several opportunities to modify the SSCD to promote consistency and ease implementation across jurisdictions. Promoting consistent implementation supports comparability of NAS incidence estimates across jurisdictions, evaluation of prevention efforts, and allocation of resources to support families. © 2024, Association of Schools and Programs of Public Health. |
Electronic vapor product use among high school students - Youth Risk Behavior Survey, United States, 2021
Oliver BE , Jones SE , Hops ED , Ashley CL , Miech R , Mpofu JJ . MMWR Suppl 2023 72 (1) 93-99 Commercial tobacco use is the leading cause of preventable disease and death in the United States. Despite declines in overall tobacco product use among youths, disparities persist. This report uses biennial data from the 2015-2021 cycles of the nationally representative Youth Risk Behavior Survey to assess prevalence and trends in electronic vapor product (EVP) use among high school students, including ever use, current use (past 30 days), and daily use. Data from 2021 also included usual source of EVPs among students who currently used EVPs. Overall, in 2021, 36.2% had ever used EVPs, 18.0% currently used EVPs, and 5.0% used EVPs daily, with variation in prevalence by demographic characteristics. Prevalence of ever use and current use of EVPs was higher among female students than male students. Prevalence of ever use, current use, and daily use of EVPs was lower among Asian students than Black or African American (Black), Hispanic, Native Hawaiian or other Pacific Islander, White, and multiracial students. Prevalence of ever use, current use, and daily use of EVPs was higher among bisexual students than among students who were not bisexual. During 2015-2021, although ever use of EVPs decreased overall (from 44.9% to 36.2%) and current use of EVPs was stable overall, daily EVP use increased overall (from 2.0 to 5.0%) and among female (from 1.1% to 5.6%), male (from 2.8% to 4.5%), Black (from 1.1% to 3.1%), Hispanic (from 2.6% to 3.4%), multiracial (from 2.8% to 5.3%) and White (from 1.9% to 6.5%) students. Among students who currently use EVPs, 54.1% usually got or bought EVPs from a friend, family member, or someone else. Continued surveillance of EVP and other tobacco product use is necessary to document and understand youth tobacco product usage. These findings can be used to inform youth-focused tobacco prevention and control strategies at the local, state, tribal, and national levels. |
Planning for the future of maternal immunization: Building on lessons learned from the COVID-19 pandemic
Meaney-Delman D , Carroll S , Polen K , Jatlaoui TC , Meyer S , Oliver S , Gee J , Shimabukuro T , Razzaghi H , Riley L , Galang RR , Tong V , Gilboa S , Ellington S , Cohn A . Vaccine 2024 As the worldwide COVID-19 pandemic unfolded, the clinical and public health community raced to understand SARS-CoV-2 infection and develop life-saving vaccines. Pregnant persons were disproportionately impacted, experiencing more severe illness and adverse pregnancy outcomes. And yet, when COVID-19 vaccines became available in late 2020, safety and efficacy data were not available to inform their use during pregnancy because pregnant persons were excluded from pre-authorization clinical trials. Concerns about vaccine safety during pregnancy and misinformation linking vaccination and infertility circulated widely, creating a lack of vaccine confidence. Many pregnant people initially chose not to get vaccinated, and while vaccination rates rose after safety and effectiveness data became available, COVID-19 vaccine acceptance was suboptimal and varied across racial and ethnic distribution of the pregnant population. The COVID-19 pandemic experience provided valuable insights that can inform current and future approaches to maternal vaccination against. |

Virus Evol 2016 2 (1) vew016 To end the largest known outbreak of Ebola virus disease (EVD) in West Africa and to prevent new transmissions, rapid epidemiological tracing of cases and contacts was required. The ability to quickly identify unknown sources and chains of transmission is key to ending the EVD epidemic and of even greater importance in the context of recent reports of Ebola virus (EBOV) persistence in survivors. Phylogenetic analysis of complete EBOV genomes can provide important information on the source of any new infection. A local deep sequencing facility was established at the Mateneh Ebola Treatment Centre in central Sierra Leone. The facility included all wetlab and computational resources to rapidly process EBOV diagnostic samples into full genome sequences. We produced 554 EBOV genomes from EVD cases across Sierra Leone. These genomes provided a detailed description of EBOV evolution and facilitated phylogenetic tracking of new EVD cases. Importantly, we show that linked genomic and epidemiological data can not only support contact tracing but also identify unconventional transmission chains involving body fluids, including semen. Rapid EBOV genome sequencing, when linked to epidemiological information and a comprehensive database of virus sequences across the outbreak, provided a powerful tool for public health epidemic control efforts. |
Development of COVID-19 vaccine policy - United States, 2020-2023
Oliver SE , Wallace M , Twentyman E , Moulia DL , Godfrey M , Link-Gelles R , Meyer S , Fleming-Dutra KE , Hall E , Wolicki J , MacNeil J , Bell BP , Lee GM , Daley MF , Cohn A , Wharton M . Vaccine 2023 COVID-19 vaccines represent a great scientific and public health achievement in the face of overwhelming pressures from a global pandemic, preventing millions of hospitalizations and deaths due to COVID-19 vaccines in the United States. Over 675 million doses of COVID-19 vaccines have been administered in the United States, and over 80% of the U.S. population has had at least 1 dose of a COVID-19 vaccine. Over the course of the COVID-19 pandemic in the United States, over one million people died from COVID-19, and over six million were hospitalized. It has been estimated that COVID-19 vaccines prevented more than 18 million additional hospitalizations and more than 3 million additional deaths due to COVID-19 in the United States. From the beginning of the COVID-19 pandemic in 2020 through June 2023, ACIP had 35 COVID-19 focused meetings and 24 votes for COVID-19 vaccine recommendations. ACIP had the critical task of rapidly and thoroughly reviewing emerging and evolving data on COVID-19 epidemiology and vaccines, as well as making comprehensive population-based recommendations for vaccine policy and considerations for implementation through a transparent and evidence-based framework. Safe and effective COVID-19 vaccines, recommended through transparent policy discussions with ACIP, remain the best tool we have to prevent serious illness, hospitalization and death from COVID-19. |
Strengthening surveillance, disease detection, and outbreak response through Guinea-Bissau's Frontline Field Epidemiology Training Program: a cross-sectional descriptive study
Camará M , da Costa FP , Chambe G , Betunde A , Cardoso P , Johnson K , Rullan-Oliver P , Lopez A . Pan Afr Med J 2023 45 133 INTRODUCTION: the goal of the Field Epidemiology Training Program (FETP) - Frontline is to strengthen the country's surveillance capacity at the district level to prepare and respond to health emergencies, including outbreaks, by training a skilled frontline public health workforce. We describe the FETP - Frontline program, including implementation, structure, achievements, impact, and its role in improving the epidemiological workforce capacity of Guinea-Bissau. METHODS: this cross-sectional descriptive study uses 2015-2019 program data collected through record reviews and historical narratives from FETP students and graduates. We generated descriptive summary statistics using the Guinea-Bissau's FETP-Frontline program database, student assignments, and investigation reports, after reviewing the FETP standardized curriculum and program guidelines. RESULTS: since its inception in 2016, FETP Frontline has implemented 14 cohorts and trained 198 frontline surveillance officers. Program participants improved surveillance data quality, investigated 51 outbreaks at national and regional levels, and contributed to disease research and surveillance in 227 separate field investigations. Participants frequently responded to priority health emergencies, including clusters or outbreaks of Zika, microencephalies, dengue, yellow fever, anthrax, malaria, and tuberculosis. CONCLUSION: Guinea-Bissau's FETP - Frontline program provides a practical example of an effective strategy to strengthen health systems through a well-prepared workforce trained to quickly detect and respond to health threats. |
Gut microbiome perturbation, antibiotic resistance, and Escherichia coli strain dynamics associated with international travel: a metagenomic analysis

Lancet Microbe 2023 4 (10) e790-e799 BACKGROUND: Culture-based studies have shown that acquisition of extended-spectrum β-lactamase-producing Enterobacterales is common during international travel; however, little is known about the role of the gut microbiome before and during travel, nor about acquisition of other antimicrobial-resistant organisms. We aimed to identify (1) whether the gut microbiome provided colonisation resistance against antimicrobial-resistant organism acquisition, (2) the effect of travel and travel behaviours on the gut microbiome, and (3) the scale and global heterogeneity of antimicrobial-resistant organism acquisition. METHODS: In this metagenomic analysis, participants were recruited at three US travel clinics (Boston, MA; New York, NY; and Salt Lake City, UT) before international travel. Participants had to travel internationally between Dec 8, 2017, and April 30, 2019, and have DNA extractions for stool samples both before and after travel for inclusion. Participants were excluded if they had at least one low coverage sample (<1 million read pairs). Stool samples were collected at home before and after travel, sent to a clinical microbiology laboratory to be screened for three target antimicrobial-resistant organisms (extended-spectrum β-lactamase-producing Enterobacterales, carbapenem-resistant Enterobacterales, and mcr-mediated colistin-resistant Enterobacterales), and underwent DNA extraction and shotgun metagenomic sequencing. We profiled metagenomes for taxonomic composition, antibiotic-resistant gene content, and characterised the Escherichia coli population at the strain level. We analysed pre-travel samples to identify the gut microbiome risk factors associated with acquisition of the three targeted antimicrobial resistant organisms. Pre-travel and post-travel samples were compared to identify microbiome and resistome perturbation and E coli strain acquisition associated with travel. FINDINGS: A total of 368 individuals travelled between the required dates, and 296 had DNA extractions available for both before and after travel. 29 travellers were excluded as they had at least one low coverage sample, leaving a final group of 267 participants. We observed a perturbation of the gut microbiota, characterised by a significant depletion of microbial diversity and enrichment of the Enterobacteriaceae family. Metagenomic strain tracking confirmed that 67% of travellers acquired new strains of E coli during travel that were phylogenetically distinct from their pre-travel strains. We observed widespread enrichment of antibiotic-resistant genes in the gut, with a median 15% (95% CI 10-20, p<1 × 10(-10)) increase in burden (reads per kilobase per million reads). This increase included antibiotic-resistant genes previously classified as threats to public health, which were 56% (95% CI 36-91, p=2 × 10(-11)) higher in abundance after travel than before. Fluoroquinolone antibiotic-resistant genes were aquired by 97 (54%) of 181 travellers with no detected pre-travel carriage. Although we found that visiting friends or relatives, travel to south Asia, and eating uncooked vegetables were risk factors for acquisition of the three targeted antimicrobial resistant organisms, we did not observe an association between the pre-travel microbiome structure and travel-related antimicrobial-resistant organism acquisition. INTERPRETATION: This work highlights a scale of E coli and antimicrobial-resistant organism acquisition by US travellers not apparent from previous culture-based studies, and suggests that strategies to control antimicrobial-resistant organisms addressing international traveller behaviour, rather than modulating the gut microbiome, could be worthwhile.

J Int Assoc Provid AIDS Care 2023 22 23259582231186701 The number of children newly infected with HIV dropped by 50%, from 320 000 in 2010 to 160 000 in 2021. Despite progress, ongoing gaps persist in diagnosis, continuity of care, and treatment optimization. In response, the United States President's Emergency Plan for AIDS Relief created the Faith-based Action for Scaling-Up Testing and Treatment for Epidemic Response (FASTER). Faith-based Action for Scaling-Up Testing and Treatment for Epidemic Response addressed gaps in countries with the highest unmet need by working with government to operationalize innovative interventions and ensure alignment with national priorities and with communities living with HIV to ensure the change was community-led. Between 2019 and 2021, FASTER's interventions were incorporated into national policies, absorbed by Ministries of Health, and taken up in subsequent awards and country operating plans. Continued effort is needed to sustain gains made during the FASTER initiative and to continue scaling evidence-based interventions to ensure that children and adolescents are not left behind in the global HIV response. |
A summary of the Advisory Committee for Immunization Practices (ACIP) use of a benefit-risk assessment framework during the first year of COVID-19 vaccine administration in the United States
Wallace M , Rosenblum HG , Moulia DL , Broder KR , Shimabukuro TT , Taylor CA , Havers FP , Meyer SA , Dooling K , Oliver SE , Hadler SC , Gargano JW . Vaccine 2023 41 (44) 6456-6467 To inform Advisory Committee for Immunization Practices (ACIP) COVID-19 vaccine policy decisions, we developed a benefit-risk assessment framework that directly compared the estimated benefits of COVID-19 vaccination to individuals (e.g., prevention of COVID-19-associated hospitalization) with risks associated with COVID-19 vaccines. This assessment framework originated following the identification of thrombosis with thrombocytopenia syndrome (TTS) after Janssen COVID-19 vaccination in April 2021. We adapted the benefit-risk assessment framework for use in subsequent policy decisions, including the adverse events of myocarditis and Guillain-Barre syndrome (GBS) following mRNA and Janssen COVID-19 vaccination respectively, expansion of COVID-19 vaccine approvals or authorizations to new age groups, and use of booster doses. Over the first year of COVID-19 vaccine administration in the United States (December 2020-December 2021), we used the benefit-risk assessment framework to inform seven different ACIP policy decisions. This framework allowed for rapid and direct comparison of the benefits and potential harms of vaccination, which may be helpful in informing other vaccine policy decisions. The assessments were a useful tool for decision-making but required reliable and granular data to stratify analyses and appropriately focus on populations most at risk for a specific adverse event. Additionally, careful decision-making was needed on parameters for data inputs. Sensitivity analyses were used where data were limited or uncertain; adjustments in the methodology were made over time to ensure the assessments remained relevant and applicable to the policy questions under consideration. |

We investigated self-reported mask use among subjects aged 18 years and older participating in the COVID-19 Community Research Partnership (CRP), a prospective longitudinal COVID-19 surveillance study in the mid-Atlantic and southeastern United States. We included those participants who completed >=5 daily surveys each month from December 1, 2020 through August 31, 2021. Mask use was defined as self-reported use of a face mask or face covering on every interaction with others outside the household within a distance of less than 6 feet. Participants were considered vaccinated if they reported receiving >=1 COVID-19 vaccine dose. Participants (n=17,522) were 91% non-Hispanic White, 68% female, median age 57 years, 26% healthcare workers, with 95% self-reported receiving >=1 COVID-19 vaccine dose through August; mean daily survey response was 85%. Mask use was higher among vaccinated than unvaccinated participants across the study period, regardless of the month of the first dose. Mask use remained relatively stable from December 2020 through April (range 71-80% unvaccinated; 86-93% vaccinated) and declined in both groups beginning in mid-May 2021 to 34% and 42% respectively in June 2021; mask use has increased again since July 2021. Mask use by all was lower during weekends and on Christmas and Easter, regardless of vaccination status. Independent predictors of higher mask use were vaccination, age >=65 years, female sex, racial or ethnic minority group, and healthcare worker occupation, whereas a history of self-reported prior COVID-19 illness was associated with lower use.

Interim recommendations for use of bivalent mRNA COVID-19 vaccines for persons aged 6 months - United States, April 2023
Moulia DL , Wallace M , Roper LE , Godfrey M , Rosenblum HG , Link-Gelles R , Britton A , Daley MF , Meyer S , Fleming-Dutra KE , Oliver SE , Twentyman E . MMWR Morb Mortal Wkly Rep 2023 72 (24) 657-662 Throughout the national public health emergency declared in response to the COVID-19 pandemic, CDC, guided by the Advisory Committee on Immunization Practices (ACIP), has offered evidence-based recommendations for the use of COVID-19 vaccines in U.S. populations after each regulatory action by the Food and Drug Administration (FDA). During August 2022-April 2023, FDA amended its Emergency Use Authorizations (EUAs) to authorize the use of a single, age-appropriate, bivalent COVID-19 vaccine dose (i.e., containing components from the ancestral and Omicron BA.4/BA.5 strains in equal amounts) for all persons aged ≥6 years, use of bivalent COVID-19 vaccine doses for children aged 6 months-5 years, and additional bivalent doses for immunocompromised persons and adults aged ≥65 years (1). ACIP voted in September 2022 on the use of the bivalent vaccine, and CDC made recommendations after the September vote and subsequently, through April 2023, with input from ACIP. This transition to a single bivalent COVID-19 vaccine dose for most persons, with additional doses for persons at increased risk for severe disease, facilitates implementation of simpler, more flexible recommendations. Three COVID-19 vaccines are currently available for use in the United States and recommended by ACIP: 1) the bivalent mRNA Pfizer-BioNTech COVID-19 vaccine, 2) the bivalent mRNA Moderna COVID-19 vaccine, and 3) the monovalent adjuvanted, protein subunit-based Novavax COVID-19 vaccine.* As of August 31, 2022, monovalent mRNA vaccines based on the ancestral SARS-CoV-2 strain are no longer authorized for use in the United States (1). |
Bridging the Gap Among Clinical Practice Guidelines for Pain Management in Cancer and Sickle Cell Disease
Schatz AA , Oliver TK , Swarm RA , Paice JA , Darbari DS , Dowell D , Meghani SH , Winckworth-Prejsnar K , Bruera E , Plovnick RM , Richardson L , Vapiwala N , Wollins D , Hudis CA , Carlson RW . J Natl Compr Canc Netw 2020 18 (4) 392-399 Opioids are a critical component of pain relief strategies for the management of patients with cancer and sickle cell disease. The escalation of opioid addiction and overdose in the United States has led to increased scrutiny of opioid prescribing practices. Multiple reports have revealed that regulatory and coverage policies, intended to curb inappropriate opioid use, have created significant barriers for many patients. The Centers for Disease Control and Prevention, National Comprehensive Cancer Network, and American Society of Clinical Oncology each publish clinical practice guidelines for the management of chronic pain. A recent JAMA Oncology article highlighted perceived variability in recommendations among these guidelines. In response, leadership from guideline organizations, government representatives, and authors of the original article met to discuss challenges and solutions. The meeting featured remarks by the Commissioner of Food and Drugs, presentations on each clinical practice guideline, an overview of the pain management needs of patients with sickle cell disease, an overview of perceived differences among guidelines, and a discussion of differences and commonalities among the guidelines. The meeting revealed that although each guideline varies in the intended patient population, target audience, and methodology, there is no disagreement among recommendations when applied to the appropriate patient and clinical situation. It was determined that clarification and education are needed regarding the intent, patient population, and scope of each clinical practice guideline, rather than harmonization of guideline recommendations. Clinical practice guidelines can serve as a resource for policymakers and payers to inform policy and coverage determinations. |
The Advisory Committee on Immunization Practices' Ethical Principles for Allocating Initial Supplies of COVID-19 Vaccine-United States, 2020.
McClung N , Chamberland M , Kinlaw K , Matthew DB , Wallace M , Bell BP , Lee GM , Talbot HK , Romero JR , Oliver SE , Dooling K . Am J Transplant 2021 21 (1) 420-425 To reduce the spread of SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19) and its associated impacts on health and society, COVID-19 vaccines are essential. The U.S. government is working to produce and deliver safe and effective COVID-19 vaccines for the entire U.S. population. The Advisory Committee on Immunization Practices (ACIP)1 has broadly outlined its approach for developing recommendations for the use of each COVID-19 vaccine authorized or approved by the Food and Drug Administration (FDA) for Emergency Use Authorization or licensure.1 ACIP’s recommendation process includes an explicit and transparent evidence-based method for assessing a vaccine’s safety and efficacy as well as consideration of other factors, including implementation.2 Because the initial supply of vaccine will likely be limited, ACIP will also recommend which groups should receive the earliest allocations of vaccine. The ACIP COVID-19 Vaccines Work Group and consultants with expertise in ethics and health equity considered external expert committee reports and published literature and deliberated the ethical issues associated with COVID-19 vaccine allocation decisions. The purpose of this report is to describe the four ethical principles that will assist ACIP in formulating recommendations for the allocation of COVID-19 vaccine while supply is limited, in addition to scientific data and implementation feasibility: (1) maximize benefits and minimize harms; (2) promote justice; (3) mitigate health inequities; and (4) promote transparency. These principles can also aid state, tribal, local, and territorial public health authorities as they develop vaccine implementation strategies within their own communities based on ACIP recommendations. |

Watkins J , Gross C , Godfrey-Johnson D , Allen-Bridson K , Hebden JN , Wright MO . Am J Infect Control 2021 49 (8) 1075-1077 This case study is part of a series centered on the Centers for Disease Control and Prevention/National Healthcare Safety Network (NHSN) healthcare-associated infection (HAI) surveillance definitions. This specific case study focuses on the application of the Pneumonia (PNEU), Ventilator-associated event (VAE), and Bloodstream infections (BSI) surveillance definitions to a patient with COVID-19. The intent of the case study series is to foster standardized application of the NHSN HAI surveillance definitions among Infection Preventionists (IPs) and encourage accurate determination of HAI events. |
Innovations in public health surveillance: updates from a forum convened by the WHO Hub for Pandemic and Epidemic Intelligence, 2 and 3 February 2022.

Euro Surveill 2022 27 (15) In the 2 years since the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) there has been an unprecedented collective effort from the academic, public, and private sectors to advance surveillance for pandemic preparedness and response. The coronavirus disease (COVID-19) pandemic has created momentum that will define the future of public health intelligence. On 2 and 3 February 2022, the World Health Organization (WHO) Hub for Pandemic and Epidemic Intelligence convened a meeting of a small group of surveillance innovators to share insights and approaches about their initiatives and future directions. The meeting served as an opportunity for participants to share updates about their work, to explore potential for collaboration, exchange ideas, cross-fertilise our work and discuss challenges in the field of surveillance. Although the group of attendees was not geographically representative of the global surveillance community, the meeting was the first in a planned series of exchanges convened by the WHO Pandemic Hub that will generate dialogue among global thought leaders and new voices in the surveillance community. In this first convening we discussed several themes, including what is meaningful collaboration for success; how to bring the public back into public health; what are individual-centred approaches; how new kinds of data have new privacy concerns; how government structures affect the functioning of surveillance systems; how to inform the decisionmaking process; cross-scaling and down-scaling tools and technologies; investing in human talent and future practitioners; and achieving sustainability into surveillance. In this meeting report, we summarise the discussions on innovations in public health surveillance and provide a list with references and links to the organisations and initiatives represented at the meeting. |
Secondary cases of invasive disease caused by encapsulated and nontypeable haemophilus influenzae - 10 U.S. Jurisdictions, 2011-2018
Oliver SE , Rubis AB , Soeters HM , Reingold A , Barnes M , Petit S , Moore AE , Harrison LH , Lynfield R , Angeles KM , Burzlaff KE , Thomas A , Schaffner W , Marjuki H , Wang X , Hariri S . MMWR Morb Mortal Wkly Rep 2023 72 (15) 386-390 Haemophilus influenzae (Hi) can cause meningitis and other serious invasive disease. Encapsulated Hi is classified into six serotypes (a-f) based on chemical composition of the polysaccharide capsule; unencapsulated strains are termed nontypeable Hi (NTHi). Hi serotype b (Hib) was the most common cause of bacterial meningitis in children in the pre-Hib vaccine era, and secondary transmission of Hi among children (e.g., to household contacts and in child care facilities) (1,2) led to the Advisory Committee on Immunization Practices (ACIP) recommendation for antibiotic chemoprophylaxis to prevent Hib disease in certain circumstances.* High Hib vaccination coverage since the 1990s has substantially reduced Hib disease, and other serotypes now account for most Hi-associated invasive disease in the United States (3). Nevertheless, CDC does not currently recommend chemoprophylaxis for contacts of persons with invasive disease caused by serotypes other than Hib and by NTHi (non-b Hi). Given this changing epidemiology, U.S. surveillance data were reviewed to investigate secondary cases of invasive disease caused by Hi. The estimated prevalence of secondary transmission was 0.32% among persons with encapsulated Hi disease (≤60 days of one another) and 0.12% among persons with NTHi disease (≤14 days of one another). Isolates from all Hi case pairs were genetically closely related, and all patients with potential secondary infection had underlying medical conditions. These results strongly suggest that secondary transmission of non-b Hi occurs. Expansion of Hi chemoprophylaxis recommendations might be warranted to control invasive Hi disease in certain populations in the United States, but further analysis is needed to evaluate the potential benefits against the risks, such as increased antibiotic use. |
Safety and effectiveness of maternal COVID-19 vaccines among pregnant people and infants
Fleming-Dutra KE , Zauche LH , Roper LE , Ellington SR , Olson CK , Sharma AJ , Woodworth KR , Tepper N , Havers F , Oliver SE , Twentyman E , Jatlaoui TC . Obstet Gynecol Clin North Am 2023 50 (2) 279-297 Evidence has consistently demonstrated that COVID-19 messenger RNA (mRNA) vaccines are safe when given during pregnancy. COVID-19 mRNA vaccines protect pregnant people and their infants who are too young to receive COVID-19 vaccines. Although generally protective, monovalent vaccine effectiveness was lower during SARS-CoV-2 Omicron variant predominance, in part due to changes in the Omicron spike protein. Bivalent vaccines, that combine ancestral strain and Omicron variant, may improve protection against Omicron variants. Everyone, including pregnant people, should stay up to date with recommended COVID-19 vaccines and bivalent booster, when eligible. |
Epidemiology of invasive nontypeable Haemophilus influenzae disease-United States, 2008-2019.
Oliver SE , Rubis AB , Soeters HM , Reingold A , Barnes M , Petit S , Farley MM , Harrison LH , Como-Sabetti K , Khanlian SA , Wester R , Thomas A , Schaffner W , Marjuki H , Wang X , Hariri S . Clin Infect Dis 2023 76 (11) 1889-1895 BACKGROUND: Nontypeable Haemophilus influenzae (NTHi) is the most common cause of invasive H. influenzae disease in the United States. We evaluated the epidemiology of invasive NTHi disease in the United States, including among pregnant women, infants, and people with HIV (PWH). METHODS: We used data from population- and laboratory-based surveillance for invasive H. influenzae disease conducted in 10 sites to estimate national incidence of NTHi, and to describe epidemiology in women of childbearing age, infants aged ≤30 days (neonates), and PWH living in the surveillance catchment areas. H. influenzae isolates were sent to the Centers for Disease Control and Prevention for species confirmation, serotyping, and whole genome sequencing of select isolates. RESULTS: During 2008-2019, average annual NTHi incidence in the United States was 1.3/100,000 population overall, 5.8/100,000 among children aged <1 year and 10.2/100,000 among adults aged ≥80 years. Among 225 reported neonates with NTHi, 92% had a positive culture within the first week of life and 72% were preterm. NTHi risk was 23 times higher among preterm compared to term neonates, and 5.6 times higher in pregnant/postpartum compared to non-pregnant women. Over half of pregnant women with invasive NTHi had loss of pregnancy post-infection. Incidence among PWH aged ≥13 years was 9.5 cases per 100,000, compared to 1.1 cases per 100,000 for non-PWH (RR=8.3; 95% CI=7.1-9.7; p<0.0001). CONCLUSION: NTHi causes substantial invasive disease, especially among older adults, pregnant/postpartum women, and neonates. Enhanced surveillance and evaluation of targeted interventions to prevent perinatal NTHi infections may be warranted. |
Effectiveness of Pfizer-BioNTech COVID-19 vaccine as evidence for policy action: A rapid systematic review and meta-analysis of non-randomized studies.
Wallace M , Collins JP , Moline H , Plumb ID , Godfrey M , Morgan RL , Campos-Outcalt D , Oliver SE , Dooling K , Gargano JW . PLoS One 2022 17 (12) e0278624 In December 2020, an interim recommendation for the use of Pfizer-BioNTech COVID-19 vaccine in persons aged ≥16 years was made under Food and Drug Administration's Emergency Use Authorization. In preparation for Biologics License Application approval, we conducted a systematic review and meta-analysis to inform the U.S. Centers for Disease Control and Prevention's Advisory Committee for Immunization Practice's (ACIP) decision-making for a standard recommendation. We conducted a rapid systematic review and meta-analysis of Pfizer-BioNTech vaccine effectiveness (VE) against symptomatic COVID-19, hospitalization due to COVID-19, death due to COVID-19, and asymptomatic SARS-CoV-2 infection. We identified studies through August 20, 2021 from an ongoing systematic review conducted by the International Vaccine Access Center and the World Health Organization. We evaluated each study for risk of bias using the Newcastle-Ottawa Scale. Pooled estimates were calculated using meta-analysis. The body of evidence for each outcome was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. We identified 80 articles, selected 35 for full-text review, and included 26. The pooled VE of Pfizer-BioNTech COVID-19 vaccine was 92.4% (95% CI: 87.5%-95.3%) against symptomatic COVID-19 with moderate evidence certainty (eight studies), 94.3% (95% CI: 87.9%-97.3%) against hospitalization due to COVID-19 with moderate certainty (eight studies), 96.1% (95% CI: 91.5%-98.2%) against death due to COVID-19 with moderate certainty (four studies), and 89.3% (88.4%-90.1%) against asymptomatic SARS-CoV-2 infection with very low certainty (two studies). The Pfizer-BioNTech COVID-19 vaccine demonstrated high effectiveness in all pre-specified outcomes and extended knowledge of the vaccine's benefits to outcomes and populations not informed by the RCTs. Use of an existing systematic review facilitated a rapid meta-analysis to inform an ACIP policy decision. This approach can be utilized as additional COVID-19 vaccines are considered for standard recommendations by ACIP. |
Child abuse-related homicides precipitated by caregiver use of harsh physical punishment
Wilson RF , Afifi TO , Yuan K , Lyons BH , Fortson BL , Oliver C , Watson A , Self-Brown S . Child Abuse Negl 2022 135 105953 BACKGROUND: Physical punishment (PP), which may involve the use of physical force, has been linked to negative effects in children and can escalate to abusive or harsh PP, resulting in injury or death. OBJECTIVE: To examine characteristics associated with fatal abuse involving caregiver use of harsh PP. METHODS: Data were from the National Violent Death Reporting System in 40 states, the District of Columbia, and Puerto Rico for years 2012-2018. Qualitative analysis was used to code textual material into categorial data, and logistic regression was used to examine associations between various characteristics and harsh PP. RESULTS: Approximately 4% (n=87) of the 2414 abuse-related homicides were known to have been precipitated by caregiver use of harsh PP. In adjusted models, homicides had greater odds of being harsh PP-related when incidents involved mothers' male companions (versus fathers), victims had a previous nonfatal injury (versus no previous nonfatal injury), and another adult participated in the fatal incident or had awareness of prior abuse/neglect (versus those without this characteristic). Two common precipitators of caregivers' use of harsh PP were: 1) child had a bathroom-related accident/soiled clothes (23.0%; n=20), and 2) child disobeyed a directive given by the perpetrator (17.2%; n=15). CONCLUSIONS: This study highlights characteristics associated with fatal abuse precipitated by caregiver use of harsh PP. Children were physically punished for developmentally normative behaviors. Ensuring caregivers are aware of and use effective parenting practices that focus on use of nonphysical discipline and promote healthy child development, may help decrease harsh PP and physical abuse-related homicides among children. |
Interim Recommendations from the Advisory Committee on Immunization Practices for the Use of Bivalent Booster Doses of COVID-19 Vaccines - United States, October 2022.

MMWR Morb Mortal Wkly Rep 2022 71 (45) 1436-1441 Four COVID-19 vaccines are currently approved for primary series vaccination in the United States under a Biologics License Application or authorized under an emergency use authorization (EUA) by the Food and Drug Administration (FDA), and recommended for primary series vaccination by the Advisory Committee on Immunization Practices (ACIP): 1) the 2- or 3-dose monovalent mRNA BNT162b2 (Pfizer-BioNTech, Comirnaty) COVID-19 vaccine; 2) the 2- or 3-dose monovalent mRNA mRNA-1273 (Moderna, Spikevax) COVID-19 vaccine; 3) the single-dose adenovirus vector-based Ad26.COV.S (Janssen [Johnson & Johnson]) COVID-19 vaccine; and 4) the 2-dose adjuvanted, protein subunit-based NVX-CoV2373 (Novavax) COVID-19 vaccine. The number of doses recommended is based on recipient age and immunocompromise status (1). For additional protection, FDA has amended EUAs to allow for COVID-19 booster doses in eligible persons (1). Because COVID-19 vaccines have demonstrated decreased effectiveness during the period when the Omicron variant (B.1.1.529) of SARS-CoV-2 predominated, bivalent booster doses (i.e., vaccine with equal components from the ancestral and Omicron strains) were considered for the express purpose of improving protection conferred by COVID-19 vaccine booster doses (2). During September-October 2022, FDA authorized bivalent mRNA vaccines for use as a booster dose in persons aged ≥5 years who completed any FDA-approved or FDA-authorized primary series and removed EUAs for monovalent COVID-19 booster doses (1). Pfizer-BioNTech and Moderna bivalent booster vaccines each contain equal amounts of spike mRNA from the ancestral and Omicron BA.4/BA.5 strains. After the EUA amendments, ACIP and CDC recommended that all persons aged ≥5 years receive 1 bivalent mRNA booster dose ≥2 months after completion of any FDA-approved or FDA-authorized monovalent primary series or monovalent booster doses. |
Interim Recommendation of the Advisory Committee on Immunization Practices for Use of the Novavax COVID-19 Vaccine in Persons Aged ≥18 years - United States, July 2022.
Twentyman E , Wallace M , Roper LE , Anderson TC , Rubis AB , Fleming-Dutra KE , Hall E , Hsu J , Rosenblum HG , Godfrey M , Archer WR , Moulia DL , Daniel L , Brooks O , Talbot HK , Lee GM , Bell BP , Daley M , Meyer S , Oliver SE . MMWR Morb Mortal Wkly Rep 2022 71 (31) 988-992 The NVX-CoV2373 (Novavax) COVID-19 vaccine is a recombinant spike (rS) protein nanoparticle vaccine with Matrix-M adjuvant to protect against infection with SARS-CoV-2, the virus that causes COVID-19. On July 13, 2022, the Food and Drug Administration (FDA) issued Emergency Use Authorization (EUA) for the Novavax vaccine for primary COVID-19 immunization of unvaccinated adults aged ≥18 years, administered as 2 doses (5 μg rS and 50 μg Matrix-M adjuvant in each dose) 3 weeks apart (1). On July 19, 2022, the Advisory Committee on Immunization Practices (ACIP) issued an interim recommendation for use of the Novavax vaccine in persons aged ≥18 years for the prevention of COVID-19.* In the per-protocol(†) efficacy analysis, vaccine efficacy (VE) against reverse transcription-polymerase chain reaction (RT-PCR)-confirmed symptomatic COVID-19 was 89.6% (95% CI = 82.4%-93.8%). The Alpha variant (B.1.1.7) of SARS-CoV-2 was the predominant circulating variant during the period of case accrual for VE assessments. Cases of myocarditis or pericarditis were reported in temporal association with vaccination, suggesting a possible causal relationship. The ACIP recommendation for the use of the Novavax COVID-19 vaccine is interim and will be updated as additional information becomes available. The adjuvanted, protein subunit-based Novavax COVID-19 vaccine provides an additional option for unvaccinated adults, increasing flexibility for the public and for vaccine providers. Vaccination is important for protection against COVID-19. |
A comparison of horizontal and transovarial transmission efficiency of Borrelia miyamotoi by Ixodes scapularis
Lynn GE , Breuner NE , Hojgaard A , Oliver J , Eisen L , Eisen RJ . Ticks Tick Borne Dis 2022 13 (5) 102003 Borrelia miyamotoi is a relapsing fever spirochete carried by Ixodes spp. ticks throughout the northern hemisphere. The pathogen is acquired either transovarially (vertically) or horizontally through blood-feeding and passed transtadially across life stages. Despite these complementary modes of transmission, infection prevalence of ticks with B. miyamotoi is typically low (<5%) in natural settings and the relative contributions of the two transmission modes have not been studied extensively. Horizontal transmission of B. miyamotoi (strain CT13-2396 or wild type strain) was initiated using infected Ixodes scapularis larvae or nymphs to expose rodents, which included both the immunocompetent CD-1 laboratory mouse (Mus musculus) and a natural reservoir host, the white-footed mouse (Peromyscus. leucopus), to simulate natural enzootic transmission. Transovarial transmission was evaluated using I. scapularis exposed to B. miyamotoi as either larvae or nymphs feeding on immunocompromised SCID mice (M. musculus) and subsequently fed as females on New Zealand white rabbits. Larvae from infected females were qPCR-tested individually to assess transovarial transmission rates. Tissue tropism of B. miyamotoi in infected ticks was demonstrated using in situ hybridization. Between 1 and 12% of ticks were positive (post-molt) for B. miyamotoi after feeding on groups of CD-1 mice or P. leucopus with evidence of infection, indicating that horizontal transmission was inefficient, regardless of whether infected larvae or nymphs were used to challenge the mice. Transovarial transmission occurred in 7 of 10 egg clutches from infected females. Filial infection prevalence in larvae ranged from 3 to 100% (median 71%). Both larval infection prevalence and spirochete load were highly correlated with maternal spirochete load. Spirochetes were disseminated throughout the tissues of all three stages of unfed ticks, including the salivary glands and female ovarian tissue. The results indicate that while multiple transmission routes contribute to enzootic maintenance of B. miyamotoi, transovarial transmission is likely to be the primary source of infected ticks and therefore risk assessment and tick control strategies should target adult female ticks. |
Clinical characteristics, health care utilization, and outcomes among patients in a pilot surveillance system for invasive mold disease-Georgia, United States, 2017-2019
Gold JAW , Revis A , Thomas S , Perry L , Blakney RA , Chambers T , Bentz ML , Berkow EL , Lockhart SR , Lysen C , Nunnally NS , Jordan A , Kelly HC , Montero AJ , Farley MM , Oliver NT , Pouch SM , Webster AS , Jackson BR , Beer KD . Open Forum Infect Dis 2022 9 (7) ofac215 BACKGROUND: Invasive mold diseases (IMDs) cause severe illness, but public health surveillance data are lacking. We describe data collected from a laboratory-based, pilot IMD surveillance system. METHODS: During 2017-2019, the Emerging Infections Program conducted active IMD surveillance at 3 Atlanta-area hospitals. We ascertained potential cases by reviewing histopathology, culture, and Aspergillus galactomannan results and classified patients as having an IMD case (based on European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group [MSG] criteria) or a non-MSG IMD case (based on the treating clinician's diagnosis and use of mold-active antifungal therapy). We described patient features and compared patients with MSG vs non-MSG IMD cases. RESULTS: Among 304 patients with potential IMD, 104 (34.2%) met an IMD case definition (41 MSG, 63 non-MSG). The most common IMD types were invasive aspergillosis (n=66 [63.5%]), mucormycosis (n=8 [7.7%]), and fusariosis (n=4 [3.8%]); the most frequently affected body sites were pulmonary (n=66 [63.5%]), otorhinolaryngologic (n=17 [16.3%]), and cutaneous/deep tissue (n=9 [8.7%]). Forty-five (43.3%) IMD patients received intensive care unit-level care, and 90-day all-cause mortality was 32.7%; these outcomes did not differ significantly between MSG and non-MSG IMD patients. CONCLUSIONS: IMD patients had high mortality rates and a variety of clinical presentations. Comprehensive IMD surveillance is needed to assess emerging trends, and strict application of MSG criteria for surveillance might exclude over one-half of clinically significant IMD cases. |
Prevalence and characteristics of CKD in the US Military Health System: A retrospective cohort study
Oliver JD3rd , Nee R , Grunwald LR , Banaag A , Pavkov ME , Burrows NR , Koehlmoos TP , Marks ES . Kidney Med 2022 4 (7) 100487 RATIONALE & OBJECTIVE: The US Military Health System (MHS) is a global health care network with a diverse population that is more representative of the US population than other study cohorts and with fewer disparities in health care access. We aimed to examine the prevalence of chronic kidney disease (CKD) in the MHS and within demographic subpopulations. STUDY DESIGN: Multiple cross-sectional analyses of demographic and claims-based data extracted from the MHS Data Repository, 1 for each fiscal year from 2006-2015. SETTING & POPULATION: Multicenter health care network including active-duty military, retirees, and dependents. The average yearly sample size was 3,285,348 individuals. EXPOSURES: Age, sex, race, active-duty status, and active-duty rank (a surrogate for socioeconomic status). OUTCOME: CKD, defined as the presence of matching International Classification of Diseases, Ninth Revision, codes on either 1 or more inpatient or 2 or more outpatient encounters. ANALYTICAL APPROACH: t test for continuous variables and χ(2) test for categorical variables; multivariable logistic regression for odds ratios. RESULTS: For 2015, the mean (standard deviation) age was 38 (16). Crude CKD prevalence was 2.9%. Age-adjusted prevalence was 4.9% overall-1.9% active-duty and 5.4% non-active-duty individuals. ORs for CKD were calculated with multiple imputations to account for missing data on race. After adjustment, the ORs for CKD (all P < 0.001) were 1.63 (95% CI, 1.62-1.64) for an age greater than 40 years, 1.16 (95% CI, 1.15-1.17) for Black race, 1.15 (95% CI, 1.14-1.16) for senior enlisted rank, 0.94 (95% CI, 0.93-0.95) for women, and 0.50 (95% CI, 0.49-0.51) for active-duty status. LIMITATIONS: Retrospective study based on International Classification of Diseases, Ninth Revision, coding. CONCLUSIONS: Within the MHS, older age, Black race, and senior enlisted rank were associated with a higher risk of CKD, whereas female sex and active-duty status were associated with a lower risk. |
