Social Determinants of Health and Health-Related Social Needs Among Adults With Chronic Diseases in the United States, Behavioral Risk Factor Surveillance System, 2022
Hacker K , Thomas CW , Zhao G , Claxton JS , Eke P , Town M . Prev Chronic Dis 2024 21 E94 INTRODUCTION: The relationship between social determinants of health (SDOH) and health-related social needs (HRSN) and some chronic diseases at the population level is not well known. We sought to determine relationships between SDOH/HRSN and major chronic diseases among US adults by using data from the 2022 Behavioral Risk Factor Surveillance System (BRFSS). METHODS: We used data from the new Social Determinants and Health Equity (SD/HE) module, conducted in 39 states, the District of Columbia, and 2 territories as part of the 2022 BRFSS. These data yielded a sample of 324,631 adult participants (aged ≥18 y). We examined 12 indicators of SDOH/HRSN and 9 chronic diseases. We calculated weighted prevalence estimates for each SDOH/HRSN measure for each chronic disease and associations between each SDOH/HRSN and each chronic disease. RESULTS: Two-thirds of participants (66.3%) had 1 or more chronic diseases, and 59.4% reported 1 or more adverse SDOH/HRSN. Prevalence estimates for individual SDOH/HRSN measures were generally higher among participants with chronic diseases (except cancer). The more chronic diseases reported, the more likely participants were to have SDOH/HRSN (P < .05 for linear trend). The leading SDOH/HRSN measures associated with each chronic disease varied; however, the most common were mental stress, receiving food stamps or participating in the Supplemental Nutrition Assistance Program, cost as a barrier for needed medical care, and life dissatisfaction. CONCLUSION: From a treatment and prevention perspective, health care providers should consider the influence of SDOH/HRSN on people with or at risk for chronic diseases. Additionally, human service and public health systems in communities with high rates of chronic disease should consider these findings as they plan to mitigate adverse SDOH. |
Severe and fatal Rocky Mountain spotted fever after exposure in Tecate, Mexico - California, July 2023-January 2024
Kjemtrup AM , Hacker JK , Monroe M , Williams V , Lines C , Lopez K , Paddock CD , Carpenter A , Salzer JS , Villalba JA , Bhatnagar J , Shah S , Iniguez-Stevens E , Efthemeou TC , Hernandez V , Vugia DJ , Kramer VL . MMWR Morb Mortal Wkly Rep 2024 73 (47) 1069-1075 Rocky Mountain spotted fever (RMSF) is a tickborne disease endemic in areas of the Americas. Persistent high incidence of the disease exists in northern Mexico, perpetuated by local populations of brown dog ticks (Rhipicephalus sanguineus sensu lato) and free-roaming dogs. Six cases of RMSF caused by Rickettsia rickettsii, including three deaths, were reported to the California Department of Public Health during July 2023-January 2024. All six patients were eventually determined to have had exposure to R. rickettsii in Tecate, Mexico, a municipality on the U.S. border that had not been previously described as a high-risk RMSF area. Identification and reporting of the cases were complicated by challenges in diagnosis. The serious nature of the disease and delays in initiating appropriate treatment can result in life-threatening consequences. Epidemiologic collaborations among local, state, federal, and international public health agencies were essential to identifying Tecate as the location of exposure. Further collaborations will be important for directing future prevention measures. Increased health care provider awareness of RMSF is critical on both sides of the border to facilitate earlier diagnosis and initiation of appropriate treatment. |
Building healthy, equitable, and resilient communities: Lessons learned from multisector community partnerships addressing the social determinants of health
DePriest K , Glasgow L , Bayer EM , Weiss S , Hacker K . J Public Health Manag Pract 2024 CONTEXT: Multisector community partnerships play a pivotal role in public health strategy for understanding and addressing social determinants of health (SDOH) and promoting health equity. The work of these partnerships is well aligned with building community resilience. PROGRAM: The Year 2 Improving Social Determinants of Health-Getting Further Faster (GFF) retrospective evaluation was designed to gather practice-based evidence that can inform future community-driven partnerships to improve chronic disease outcomes and advance health equity by addressing social determinants of health (SDOH). IMPLEMENTATION: This paper sought to determine how the efforts of multisector community partnerships could also support community resilience. Guided by CDC's Framework for Program Evaluation in Public Health and health equity principles, the GFF evaluation engaged 14 Multisector Community Partnerships to better understand how their SDOH interventions contribute to community changes that improve chronic diseases and advance health equity. Data collection included qualitative discussions along with additional quantitative analyses of SDOH outcomes, costs, and prevention impacts. This paper focuses on insights gathered from qualitative discussions (2 virtual 60-minute discussions with members of each of the 14 Partnerships) around community resilience. EVALUATION: Results from qualitative discussions demonstrate how Partnerships' SDOH efforts created parallel opportunities for nurturing community resilience. For example, Partnerships engaged community members in the design and implementation of SDOH interventions in ways that nurtured a sense of belonging and empowerment to shape their community. To further build community resilience, Partnerships mentioned the importance of sustained and flexible funding, help building stronger partnerships, and a shared goal to build resilience and engage community members. DISCUSSION: Findings indicate that community partnerships working to address SDOH can drive reciprocal improvements in community resilience-contributions that are critical for advancing health equity. Partnerships suggested that health departments may have opportunities to enhance community resilience through their role as funder, facilitator, and convener. |
Rickettsia rickettsii subsp. californica subsp. nov., the etiologic agent of Pacific Coast tick fever
Paddock CD , Karpathy SE , Henry A , Ryle L , Hecht JA , Hacker JK , Padgett KA , Kjemtrup AM , Bullock H , Lane RS , Ladner JT . J Infect Dis 2024 ![]() ![]() The etiologic agent of Pacific Coast tick fever (PCTF), a moderately severe tickborne illness that resembles Rocky Mountain spotted fever (RMSF), was first isolated in 1966 from specimens of Dermacentor occidentalis (the Pacific Coast tick) obtained in California. For several decades, this bacterium was identified ambiguously as the unclassified spotted fever group Rickettsia species 364-D, Rickettsia 364, or Rickettsia philipii. However, none of these epithets satisfied criteria of formal bacterial nomenclature. Data developed from mouse serotyping studies performed 45 years ago, and multi-locus sequence typing several decades later, indicated that this bacterium was similar to, but distinct from isolates of Rickettsia rickettsii, the etiological agent of RMSF. We applied an integrative taxonomic approach, combining phenotypic, ecological, and clinical data with whole genome sequencing of 11 contemporary isolates of this pathogen to identify it as a distinct subspecies of R. rickettsii, and propose the name Rickettsia rickettsii subsp. californica subsp. nov. |
Notes from the field: Mpox cluster caused by tecovirimat-resistant monkeypox virus - Five States, October 2023-February 2024
Gigante CM , Takakuwa J , McGrath D , Kling C , Smith TG , Peng M , Wilkins K , Garrigues JM , Holly T , Barbian H , Kittner A , Haydel D , Ortega E , Richardson G , Hand J , Hacker JK , Espinosa A , Haw M , Kath C , Bielby M , Short K , Johnson K , De La Cruz N , Davidson W , Hughes C , Green NM , Baird N , Rao AK , Hutson CL . MMWR Morb Mortal Wkly Rep 2024 73 (40) 903-905 ![]() ![]() The antiviral drug tecovirimat* has been used extensively to treat U.S. mpox cases since the start of a global outbreak in 2022. Mutations in the mpox viral protein target (F13 or VP37) that occur during treatment can result in resistance to tecovirimat(†) (1,2). CDC and public health partners have conducted genetic surveillance of monkeypox virus (MPXV) for F13 mutations through sequencing and monitoring of public databases. MPXV F13 mutations associated with resistance have been reported since 2022, typically among severely immunocompromised mpox patients who required prolonged courses of tecovirimat (3-5). A majority of patients with infections caused by MPXV with resistant mutations had a history of tecovirimat treatment; however, spread of tecovirimat-resistant MPXV was reported in California during late 2022 to early 2023 among persons with no previous tecovirimat treatment (3). This report describes a second, unrelated cluster of tecovirimat-resistant MPXV among 18 persons with no previous history of tecovirimat treatment in multiple states. |
Sustainability strategies for multisector community partnerships addressing social determinants of health
Wiggins ST , Glasgow L , Durocher B , Bayer E , Plescia M , Holtgrave P , Hacker K . Health Promot Pract 2024 15248399241278968 Multisector community partnerships (MCPs) are a key element of the public health approach to addressing social determinants of health (SDOH). The Improving SDOH-Getting Further Faster (GFF) retrospective evaluation of MCP-driven SDOH interventions was designed to generate practice-based evidence that can help guide partnerships' efforts to improve chronic disease outcomes and advance health equity by addressing SDOH. This article shares Year 2 GFF findings related to sustainability strategies for partnerships focused on SDOH and their interventions. GFF partnerships' reported sustainability strategies, including establishing shared goals and increasing partners' capacity for SDOH work through training, align well with the rich coalition building evidence base. Findings also indicate some evolution of sustainability strategies, such as adopting team-based, decentralized leadership models to help guard against partner or staff turnover. Organizations looking to form, fund, or provide technical assistance to MCPs that address SDOH can use the practice-based insights shared in this research brief to plan ahead for sustainability. |
Engaging community health workers in the Centers For Disease Control And Prevention's COVID-19 public health response to address health disparities and build community resilience
De Jesus S , Rohan EA , DeGroff A , Vaughan M , Hayes N , Presley-Cantrell L , Buckley R , Richardson LC , Crawford G , Hacker K . Health Promot Pract 2024 15248399241267969 In 2021, the Centers for Disease Control and Prevention's (CDC) National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) funded community health workers (CHWs) for COVID Response and Resilient Communities (CCR). CCR is a 3-year, $350 million initiative to implement CHW strategies aimed at reducing COVID-19 impacts, building resilience, and improving health equity by addressing health-related social needs. This paper describes the CCR initiative and experiences to date, underscoring CHWs' critical role in CDC's pandemic response. CCR funds 67 recipients to reach communities who are disproportionately affected by long-standing health disparities (hereafter, priority populations). CCR aims to decrease the impact of COVID-19 and increase community resilience to respond to COVID-19 and future public health emergencies. Recipients implement three strategies: train CHWs to support the COVID-19 response, increase the workforce of CHWs to manage the spread of the disease, and improve utilization of community and clinical resources to engage CHWs to help strengthen communities' resilience to mitigate the impact of COVID-19. We funded three additional organizations to provide technical assistance to CCR recipients and collaborate with us on a national evaluation of the program. CCR recipients hired about 950 CHWs and integrated these CHWs into over 1,000 organizations and care teams. At the end of the second program year, CHWs made over 250,000 referrals to social services and over 150,000 referrals to address specific health conditions. CCR demonstrates that CHWs can be quickly mobilized to participate in a public health emergency and reach those most affected by COVID-19. |
Cost-effectiveness of social determinants of health interventions: Evaluating multisector community partnerships' efforts
Honeycutt AA , Khavjou OA , Tayebali Z , Dempsey M , Glasgow L , Hacker K . Am J Prev Med 2024 INTRODUCTION: The purpose of this analysis was to rapidly evaluate the potential costs, cost-effectiveness, and long-term effects of efforts by multisector community partnerships (MCPs) to improve chronic disease outcomes and advance health equity by addressing social determinants of health (SDOH). METHODS: In 2022, the evaluators partnered with 13 MCPs to collect data on start-up and ongoing costs for implementing SDOH interventions and on intervention reach and timing. In 2023, the team used the Prevention Impacts Simulation Model (PRISM) to estimate the longer-term impact of MCPs' efforts over 5-, 10-, and 20-year periods. The team also analyzed costs and cumulative 10- and 20-year cost-effectiveness of the MCPs' SDOH interventions. RESULTS: Over 20 years, SDOH interventions implemented by the 13 MCPs can potentially prevent 970 premature deaths and avert $105 million in medical costs and $408 million in productivity losses. The 20-year cumulative results show potential net costs of $38 300 per quality-adjusted life-year gained from the health care sector perspective and indicate potentially reduced costs and improved health outcomes from the societal perspective. CONCLUSIONS: These findings can help inform and provide support for future investments in SDOH interventions. With a better understanding of costs needed to start up and implement SDOH interventions, funders and MCPs can prepare for the resources required to do this work. Findings also suggest promising long-term impacts and potential cost-effectiveness for most MCP-implemented SDOH interventions. |
The community-based health workforce in public health and health care delivery
Ahmed K , Presley-Cantrell L , Moeti R , Wong D , Freese KL , Taplin C , Rodrigue J , Spencer TD , Hacker K . J Public Health Manag Pract 2024 30 (5) E264-e269 CONTEXT: The "community-based workforce" is an umbrella term used by a workgroup of U.S. Department of Health and Human Services (HHS) leaders to characterize a variety of job titles and descriptions for positions in the public health, health care delivery, and human service sectors across local communities. APPROACH: Definitions, expectations of the scope of work, and funding opportunities for this workforce vary. To address some of these challenges, a workgroup of HHS agencies met to define the roles of this workforce and identify existing opportunities for training, career advancement, and compensation. DISCUSSION: The community-based workforce has demonstrated success in improving poor health outcomes and addressing the social determinants of health for decades. However, descriptions of this workforce, expectations of their roles, and funding opportunities vary. The HHS workgroup identified that comprehensive approaches are needed within HHS and via public health sectors to meet these challenges and opportunities. CONCLUSION: Using the common term "community-based workforce" across HHS can encourage alignment and collaboration. As the environment for this public health and health care community-based workforce shifts, it will be important to understand the value and opportunities available to ensure long-term sustainability for this workforce to continue to advance health equity. |
The development of social determinants of health outcome measures: The role of multisector partnerships and community validation
Hacker K , Thomas C , Sheridan J , Glasgow L . J Public Health Manag Pract 2024 PURPOSE: To develop a set of social determinants of health (SDOH) measurements. PROBLEM: Despite burgeoning interest in addressing both SDOH and health-related social needs, the evidence on what works is limited due in part to the lack of standardized measures for evaluation. METHODS: In 2020, the Centers for Disease Control and Prevention (CDC) National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) identified 5 SDOH domains related to chronic disease for future programmatic work. These included built environment, community connections to clinical care, tobacco-free policies, social connectedness, and food and nutrition security. Subsequently, NCCDPHP launched an effort to develop a set of SDOH measures for evaluating funded programs in these domains. The approach involved a literature scan and a rating process based on 5 criteria relevant to NCCDPHP's SDOH priorities. A complementary community review by 13 multisector community partnerships (MCPs) applied a real-world public health practice lens to measure development. MCPs' ratings were analyzed to create summary scores for each measure, and open-ended feedback was synthesized using rapid qualitative analysis. RESULTS: The internal workgroup identified 59 measures from the initial 200 measures. Feedback from the MCPs identified issues of relevancy and burden of measures. Their high scores narrowed the 59 measures to 22 covering all 5 domains. In response, CDC is honing the original measures review criteria to include community perspectives. CONCLUSION: Public health measures development is often an academic pursuit. Engaging MCPs lends real-world credibility to the development of common SDOH measures. |

Racial and ethnic differences in social determinants of health and health-related social needs among adults - Behavioral Risk Factor Surveillance System, United States, 2022
Town M , Eke P , Zhao G , Thomas CW , Hsia J , Pierannunzi C , Hacker K . MMWR Morb Mortal Wkly Rep 2024 73 (9) 204-208 Social determinants of health (SDOH) are a broad array of social and contextual conditions where persons are born, live, learn, work, play, worship, and age that influence their physical and mental wellbeing and quality of life. Using 2022 Behavioral Risk Factor Surveillance System data, this study assessed measures of adverse SDOH and health-related social needs (HRSN) among U.S. adult populations. Measures included life satisfaction, social and emotional support, social isolation or loneliness, employment stability, food stability/security, housing stability/security, utility stability/security, transportation access, mental well-being, and health care access. Prevalence ratios were adjusted for age, sex, education, marital status, income, and self-rated health. Social isolation or loneliness (31.9%) and lack of social and emotional support (24.8%) were the most commonly reported measures, both of which were more prevalent among non-Hispanic (NH) American Indian or Alaska Native, NH Black or African American, NH Native Hawaiian or other Pacific Islander, NH multiracial, and Hispanic or Latino adults than among NH White adults. The majority of prevalence estimates for other adverse SDOH and HRSN were also higher across all other racial and ethnic groups (except for NH Asian) compared with NH White adults. SDOH and HRSN data can be used to monitor needed social and health resources in the U.S. population and help evaluate population-scale interventions. |
The burden of chronic disease
Hacker K . Mayo Clin Proc Innov Qual Outcomes 2024 8 (1) 112-119 Chronic diseases like diabetes, heart disease, stroke, and cancer have been and continue to be some of the major causes of worldwide morbidity and mortality. A transition between infectious and noncommunicable diseases occurred in the early 1900s as a result of improved public health and has persisted ever since. Now, as individuals live longer, the prevalence and cost of chronic disease continue to grow. The estimated cost of chronic disease is expected to reach $47 trillion worldwide by 2030. Individual lifestyle and behaviors and community factors play important roles in the development and management of chronic diseases. Many of these conditions (diabetes, heart disease, and respiratory diseases) are preventable, and their leading risk factors are physical inactivity, poor nutrition, tobacco use, and excessive alcohol. Unfortunately, the investment in prevention remains small compared with treatment, both from a lifestyle perspective and a social determinants of health perspective. Given the future trajectory of chronic disease, innovation in technology and pharmaceuticals with a concomitant investment in prevention will be required. Our future depends on it. |

Advancing chronic disease practice through the CDC Data Modernization Initiative
Carney TJ , Wiltz JL , Davis K , Briss PA , Hacker K . Prev Chronic Dis 2023 20 E110 Chronic disease affects 6 in 10 adults in the US, while 4 in 10 adults live with multiple chronic diseases (1). Chronic diseases represent one of the nation’s leading causes of disability and drivers of the nation’s $4.1 trillion in annual health care spending (1). Chronic conditions including heart disease, cancer, stroke, diabetes, and chronic kidney disease dominate the leading causes of death. Furthermore, leading lifestyle risk factors in the US include tobacco use, poor nutrition, physical inactivity, and excessive alcohol use (1). | | Chronic disease prevention and control necessitates a comprehensive strategy to prevent disease (2–4), which is needed now more than ever (5). Information systems innovations are needed to advance health activities and outcomes and to allow decision makers and practitioners to act (4,6–8). Chronic disease data are a foundation that can inform interventions to promote healthy communities, support healthy behaviors and lifestyles, and facilitate effective and coordinated chronic disease prevention and health promotion (5,9). The benefits of an improved chronic disease data landscape include improved management of chronic disease programs, enhanced communication, data exchange, and coordination between federal, state, tribal, local, and territorial health departments and their partners. Additionally, efforts aimed at enhancing chronic disease surveillance practices will better enable a learning health system, precision public health, and improved situational awareness that will ultimately allow people across the US to live longer, healthier lives (10–12). |
Community spread of a human monkeypox virus variant with a tecovirimat resistance-associated mutation
Garrigues JM , Hemarajata P , Espinosa A , Hacker JK , Wynn NT , Smith TG , Gigante CM , Davidson W , Vega J , Edmondson H , Karan A , Marutani AN , Kim M , Terashita D , Balter SE , Hutson CL , Green NM . Antimicrob Agents Chemother 2023 67 (11) e0097223 ![]() ![]() Tecovirimat, also known as TPOXX or ST-246, is a drug available for the treatment of mpox. Tecovirimat targets the conserved orthopoxvirus VP37 protein (also known as F13) required for extracellular virus particle generation (1, 2). Multiple VP37 mutations associated with tecovirimat resistance have been reported within the current global mpox outbreak in immunocompromised individuals with advanced HIV infection (3 – 5). In many of these cases, resistance mutation heterogeneity was observed following tecovirimat exposure, suggesting resistance emerged under selective pressure during treatment. | To monitor circulating monkeypox virus (MPXV) within California, a genomic surveillance network was established whereby clinical and commercial laboratories provided positive specimens for whole-genome sequencing using an amplicon-based protocol and subsequent analysis (6 – 9). Through this surveillance, 11 mpox cases were identified in southern California with the same tecovirimat resistance-associated mutation (Table 1): a three-nucleotide deletion in the vaccinia virus Copenhagen F13L gene homolog (OPG057) resulting in asparagine removed from position 267 in the VP37 protein (VP37:N267del) (5) (https://www.fda.gov/emergency-preparedness-and-response/mcm-issues/fda-mpox-response#therapeutics). VP37:N267del was the only tecovirimat resistance-associated mutation detected in identified specimens and had allele frequencies greater than 89% in all instances, suggesting infections may have occurred with predominantly mutant virus. Phenotypic testing in vitro (3 – 5) confirmed tecovirimat resistance in ten identified specimens with EC50 values ranging from 1.488 to 3.977 µM, corresponding to an 85- to 230-fold change compared to wild-type isolates. |
State insurance mandates and racial and ethnic inequities in assisted reproductive technology utilization
Korkidakis A , DeSantis CE , Kissin DM , Hacker MR , Koniares K , Yartel A , Adashi EY , Penzias AS . Fertil Steril 2023 121 (1) 54-62 OBJECTIVE: To examine whether the (1) scope of state-mandated insurance coverage for assisted reproductive technology (ART), and (2) proportion of the population eligible for this coverage, are associated with reductions in racial/ethnic inequities in ART utilization. DESIGN: National cross-sectional, ecologic study. SUBJECTS: We employed estimates from the U.S. Census Bureau of all women 20-44 years of age living in the U.S. in 2018. The number of women who initiated an ART cycle during that year that was reported to the U.S. Centers for Disease Control and Prevention (CDC) was obtained from the National ART Surveillance System (NASS). EXPOSURE: State mandates were classified by scope of required coverage for fertility services: Comprehensive, Limited, and No Mandate. MAIN OUTCOMES MEASURES: Race and ethnic-specific ART utilization rates, defined as number of women undergoing ≥1 ART cycles per 10,000 women, were the primary outcome. As state mandates do not apply to all insurance plans, Comprehensive Mandate utilization rates were recalculated using denominators corrected for the estimated proportions of populations eligible for coverage. RESULTS: Across all mandate categories, Non-Hispanic (NH) Asian and NH White populations had the highest ART utilization rates, whereas the lowest rates were among Hispanic, NH Black, and NH Other/Multiple Races populations. As compared to the NH Asian reference group, the NH Black population had smaller inequities in the Comprehensive Mandate group than the No Mandate group (Rate Ratio [RR 0.33 [0.28-0.38] versus RR 0.23 [0.22-0.24]). Using the Comprehensive Mandate group for each race/ethnicity as reference, the NH Black and NH Other/Multiple Races populations had the largest relative differences in utilization between the No Mandate and Comprehensive Mandate groups (RR 0.39 [0.37-0.41] and 0.33 [0.28-0.38], respectively). Within the Comprehensive Mandate group, the disparities in the Hispanic and NH Black populations moved towards the null after correcting for state-mandated insurance eligibility. CONCLUSIONS: Racial/ethnic inequities in ART utilization were reduced in states with comprehensive infertility coverage mandates. Inequities were further attenuated after correcting for mandate eligibility. Mandates alone, however, were not sufficient to eliminate disparities. These findings can inform future strategies aimed at improving ART access under a social justice framework. |
Fleaborne typhus-associated deaths - Los Angeles County, California, 2022
Alarcón J , Sanosyan A , Contreras ZA , Ngo VP , Carpenter A , Hacker JK , Probert WS , Terashita D , Balter S , Halai UA . MMWR Morb Mortal Wkly Rep 2023 72 (31) 838-843 Fleaborne typhus (also known as murine typhus), a widely distributed vectorborne zoonosis caused by Rickettsia typhi, is a moderately severe, but infrequently fatal illness; among patients who receive doxycycline, the case-fatality rate is <1%. Fleaborne typhus is a mandated reportable condition in California. Reported fleaborne typhus cases in Los Angeles County have been increasing since 2010, with the highest number (171) reported during 2022. During June-October 2022, Los Angeles County Department of Public Health learned of three fleaborne typhus-associated deaths. This report describes the clinical presentation, illness course, and methods used to diagnose fleaborne typhus in these three cases. Severe fleaborne typhus manifestations among these cases included hemophagocytic lymphohistiocytosis, a rare immune hyperactivation syndrome that can occur in the infection setting; myocarditis; and septic shock with disseminated intravascular coagulation. Increased health care provider and public health awareness of the prevalence and severity of fleaborne typhus and of the importance of early doxycycline therapy is essential for prevention and treatment efforts. |
Using the prevention impacts simulation model to estimate long-term impacts of multisector community partnerships' efforts to address social determinants of health
Honeycutt AA , Yarnoff B , Tayebali Z , Glasgow L , Hacker K . Prev Chronic Dis 2023 20 E62 Public health plays a key role in addressing social determinants of health (SDOH) through multisector community partnerships (MCPs), which contribute to community changes that promote healthy living; however, little is known about the longer-term impact of MCP-driven interventions. We used the Prevention Impacts Simulation Model (PRISM) in a rapid evaluation to better understand the implementation and potential impact of MCPs' SDOH initiatives. Results suggest that, if sustained, initiatives implemented by the 27 included MCPs may prevent 880 premature deaths and avert $125.7 million in medical costs over 20 years. As a validated model that estimates impact by using available implementation data, PRISM is a useful tool for evaluating SDOH initiatives. |
Key insights on multisector community partnerships from real-world efforts to address social determinants of health
Glasgow L , Clayton M , Honeycutt A , Bayer EM , Plescia M , Holtgrave PL , Hacker K . Eval Program Plann 2023 99 102298 PURPOSE: To better understand and inform how multisector community partnerships (MCPs) perform meaningful work to prevent chronic disease and advance health equity by addressing social determinants of health (SDOH). METHODS: We conducted a rapid retrospective evaluation of SDOH initiatives implemented within the past three years by 42 established MCPs across the United States. The mixed methods evaluation included document review and coding of available outcomes data, virtual discussions, and Prevention Impacts Simulation Model (PRISM) analysis. RESULTS: All 42 MCPs built community capacity for addressing SDOH through new or strengthened data systems, leveraged resources, or engaged residents, for example. Most MCPs (N = 38, 90%) reported contributions to community changes that promote healthy living. More than half of the MCPs (N = 22) reported health outcomes data for their SDOH initiatives, including improved health behaviors and clinical outcomes. Based on reach data provided by 27 MCPs, PRISM analysis results suggest that sustained initiatives could save over $633 million in productivity and medical costs cumulatively through 20 years. CONCLUSIONS: With sufficient technical assistance and funding resources, MCPs are a key component of the public health strategy to address SDOH. |

Changes in sales of e-cigarettes, cigarettes, and nicotine replacement therapy products before, during, and after the EVALI outbreak
Wang X , Kim Y , Trivers KF , Tynan MA , Shrestha SS , Emery S , Borowiecki M , Hacker K . Prev Chronic Dis 2022 19 E86 INTRODUCTION: In 2019, an outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) occurred in the US. We used Nielsen retail sales data to assess trends in sales of e-cigarettes, cigarettes, and nicotine replacement therapy (NRT) products before, during, and after the EVALI outbreak. METHODS: Monthly unit sales of e-cigarettes, cigarettes, and NRT products overall and by product type were assessed during January 2019 through June 2020 by using an interrupted time series model. Two time points were specified at the period ending July 13, 2019, and the period ending February 22, 2020, to partition before, during, and after the outbreak period. Sales trends by aggregated state-level EVALI case prevalence (low, medium, and high) were assessed to investigate interstate variations in changes of sales coinciding with the EVALI outbreak. RESULTS: Monthly e-cigarette sales increased 3.5% (P < .001) before the outbreak and decreased 3.1% (P < .001) during the outbreak, with no significant changes after the outbreak. Monthly cigarette sales increased 1.6% (P < .001) before the outbreak, decreased 1.8% (P < .001) during the outbreak, and increased 2.7% (P < .001) after the outbreak. NRT sales did not change significantly before or during the outbreak but decreased (2.8%, P = .01) after the outbreak. Sales trends by state-level EVALI case prevalence were similar to national-level sales trends. CONCLUSION: Cigarette and e-cigarette sales decreased during the EVALI outbreak, but no changes in overall NRT sales were observed until after the outbreak. Continued monitoring of tobacco sales data can provide insight into potential changes in use patterns and inform tobacco prevention and control efforts. |
Health departments' role in addressing social determinants of health in collaboration with multisector community partnerships
Emery KJ , Durocher B , Arena LC , Glasgow L , Bayer EM , Plescia M , Holtgrave PL , Hacker K . J Public Health Manag Pract 2023 29 (1) 51-55 Multisector community partnerships (MCPs) are key component of the public health strategy for addressing social determinants of health (SDOH) and promoting health equity. Governmental public health agencies are often members or leaders of MCPs, but few studies have examined the role of health departments in supporting MCPs' SDOH initiatives. We engaged 42 established MCPs in a rapid retrospective evaluation to better understand how MCPs' SDOH initiatives contribute to community changes that promote healthy living and improved health outcomes. As part of this work, we gained insights into how health departments support MCPs' SDOH initiatives, as well as opportunities for enhanced collaboration. Results indicate that health departments can support MCPs' SDOH initiatives through the provision of funding and technical assistance, data sharing, and connecting community organizations with shared missions, for example. Findings can be used to inform the development of funding opportunities and technical assistance for MCPs and health department partners. |
Getting further faster: Illuminating opportunities for health departments to support community-driven social determinants of health interventions
Hacker K , Glasgow L , Bayer EM , Holtgrave P . J Public Health Manag Pract 2023 29 (1) 105-107 Since 1980, the Healthy People initiative has developed measurable 10-year objectives to guide and evaluate our nation's efforts to improve the health and well-being of all people. Healthy People 2030 includes an overarching goal that focuses on social determinants of health (SDOH): “Create social, physical, and economic environments that promote attaining the full potential for health and well-being for all.”1 As we recover from an unprecedented pandemic, we have an opportunity to leverage recent investments in the US public health system to advance this national SDOH goal. Multisector community partnerships (MCPs) are a key component of the public health approach to addressing SDOH and promoting health equity.2 In 2020, the Centers for Disease Control and Prevention's (CDC's) National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP), National Association of County and City Health Officials (NACCHO), and Association of State and Territorial Health Officials (ASTHO) launched the Improving SDOH—Getting Further Faster (GFF) initiative, partnering with 42 established MCPs and RTI International to rapidly generate practice-based evidence that could inform and strengthen future community-driven SDOH interventions.3 GFF focuses on 5 SDOH domains with links to chronic disease: (1) built environment, (2) community-clinical linkages, (3) food and nutrition security, (4) social connectedness, and (5) tobacco-free policies. This column provides a progress update on the GFF initiative, including a brief description of ongoing work to illuminate opportunities for health departments and health care systems to support community-driven SDOH interventions. |

Am J Prev Med 2022 64 (3) 452-458 The coronavirus disease 2019 (COVID-19) pandemic has underscored the need to prevent chronic disease and promote health.1 , 2 More than a million American lives have been lost to COVID-19, and life expectancy decreased between 2018 and 2020.3 , 4 Chronic diseases are major risk factors for COVID-19 morbidity and mortality.5 In addition, COVID-19 morbidity and mortality have been higher among persons from racial and ethnic groups such as those who are African American, Hispanic or Latino, and American Indian or Alaska Native as well as those living at lower SES.6 This has magnified pre-existing health inequities in chronic disease.1 , 2 , 7 |
Social determinants of health-an approach taken at CDC
Hacker K , Auerbach J , Ikeda R , Philip C , Houry D . J Public Health Manag Pract 2022 28 (6) 589-594 In the last decade, there has been an increasing awareness of the importance of addressing the social determinants of health (SDOH), the nonmedical conditions that influence health outcomes,1 as a systemic strategy for improving health, particularly among groups that are disproportionally affected by SDOH.2 While health care is important, it is estimated that these conditions, ranging from structural racism to socioeconomic factors, drive as much as 50% of health outcomes.3 |
Exploring and mitigating plague for One Health purposes
Eads DA , Biggins DE , Wimsatt J , Eisen RJ , Hinnebusch BJ , Matchett MR , Goldberg AR , Livieri TM , Hacker GM , Novak MG , Buttke DE , Grassel SM , Hughes JP , Atiku LA . Curr Trop Med Rep 2022 9 (4) 169-184 Purpose of Review: In 2020, the Appropriations Committee for the U.S. House of Representatives directed the CDC to develop a national One Health framework to combat zoonotic diseases, including sylvatic plague, which is caused by the flea-borne bacterium Yersinia pestis. This review builds upon that multisectoral objective. We aim to increase awareness of Y. pestis and to highlight examples of plague mitigation for One Health purposes (i.e., to achieve optimal health outcomes for people, animals, plants, and their shared environment). We draw primarily upon examples from the USA, but also discuss research from Madagascar and Uganda where relevant, as Y. pestis has emerged as a zoonotic threat in those foci. Recent Findings: Historically, the bulk of plague research has been directed at the disease in humans. This is not surprising, given that Y. pestis is a scourge of human history. Nevertheless, the ecology of Y. pestis is inextricably linked to other mammals and fleas under natural conditions. Accumulating evidence demonstrates Y. pestis is an unrelenting threat to multiple ecosystems, where the bacterium is capable of significantly reducing native species abundance and diversity while altering competitive and trophic relationships, food web connections, and nutrient cycles. In doing so, Y. pestis transforms ecosystems, causing “shifting baselines syndrome” in humans, where there is a gradual shift in the accepted norms for the condition of the natural environment. Eradication of Y. pestis in nature is difficult to impossible, but effective mitigation is achievable; we discuss flea vector control and One Health implications in this context. Summary: There is an acute need to rapidly expand research on Y. pestis, across multiple host and flea species and varied ecosystems of the Western US and abroad, for human and environmental health purposes. The fate of many wildlife species hangs in the balance, and the implications for humans are profound in some regions. Collaborative multisectoral research is needed to define the scope of the problem in each epidemiological context and to identify, refine, and implement appropriate and effective mitigation practices. © 2022, This is a U.S. Government work and not under copyright protection in the US; foreign copyright protection may apply. |
A forty-year review of Rocky Mountain spotted fever cases in California shows clinical and epidemiologic changes
Kjemtrup AM , Padgett K , Paddock CD , Messenger S , Hacker JK , Feiszli T , Melgar M , Metzger ME , Hu R , Kramer VL . PLoS Negl Trop Dis 2022 16 (9) e0010738 Rocky Mountain spotted fever (RMSF) is a life-threatening tick-borne disease documented in North, Central, and South America. In California, RMSF is rare; nonetheless, recent fatal cases highlight ecological cycles of the two genera of ticks, Dermacentor and Rhipicephalus, known to transmit the disease. These ticks occur in completely different habitats (sylvatic and peridomestic, respectively) resulting in different exposure risks for humans. This study summarizes the demographic, exposure, and clinical aspects associated with the last 40 years of reported RMSF cases to the California Department of Public Health (CDPH). Seventy-eight RMSF cases with onsets from 1980 to 2019 were reviewed. The incidence of RMSF has risen in the last 20 years from 0.04 cases per million to 0.07 cases per million (a two-fold increase in reports), though the percentage of cases that were confirmed dropped significantly from 72% to 25% of all reported cases. Notably, Hispanic/Latino populations saw the greatest rise in incidence. Cases of RMSF in California result from autochthonous and out-of-state exposures. During the last 20 years, more cases reported exposure in Southern California or Mexico than in the previous 20 years. The driver of these epidemiologic changes is likely the establishment and expansion of Rhipicephalus sanguineus sensu lato ticks in Southern California and on-going outbreaks of RMSF in northern Mexico. Analysis of available electronically reported clinical data from 2011 to 2019 showed that 57% of reported cases presented with serious illness requiring hospitalization with a 7% mortality. The difficulty in recognizing RMSF is due to a non-specific clinical presentation; however, querying patients on the potential of tick exposure in both sylvatic and peridomestic environments may facilitate appropriate testing and treatment. |
Social Needs and Social Determinants: The Role of the Centers for Disease Control and Prevention and Public Health.
Hacker K , Houry D . Public Health Rep 2022 137 (6) 333549221120244 The COVID-19 pandemic has been a long and tragic public health crisis. More than 1 million people have died in the United States. Some segments of our population, including those who are African American, Hispanic, American Indian/Alaska Native, and living in low socioeconomic areas, have borne a disproportionate burden of morbidity and mortality. 1 Preexisting health disparities have been exacerbated as people delayed care, deferred prevention, and isolated at home. |
