Since the initial publication of A Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals in 2008, the prevention of healthcare-associated infections (HAIs) has continued to be a national priority. Progress in healthcare epidemiology, infection prevention, antimicrobial stewardship, and implementation science research has led to improvements in our understanding of effective strategies for HAI prevention. Despite these advances, HAIs continue to affect ∼1 of every 31 hospitalized patients, leading to substantial morbidity, mortality, and excess healthcare expenditures, and persistent gaps remain between what is recommended and what is practiced.The widespread impact of the coronavirus disease 2019 (COVID-19) pandemic on HAI outcomes in acute-care hospitals has further highlighted the essential role of infection prevention programs and the critical importance of prioritizing efforts that can be sustained even in the face of resource requirements from COVID-19 and future infectious diseases crises.The Compendium: 2022 Updates document provides acute-care hospitals with up-to-date, practical expert guidance to assist in prioritizing and implementing HAI prevention efforts. It is the product of a highly collaborative effort led by the Society for Healthcare Epidemiology of America (SHEA), the Infectious Disease Society of America (IDSA), the Association for Professionals in Infection Control and Epidemiology (APIC), the American Hospital Association (AHA), and The Joint Commission, with major contributions from representatives of organizations and societies with content expertise, including the Centers for Disease Control and Prevention (CDC), the Pediatric Infectious Disease Society (PIDS), the Society for Critical Care Medicine (SCCM), the Society for Hospital Medicine (SHM), the Surgical Infection Society (SIS), and others.

BACKGROUND: Preprints are publicly available manuscripts posted to various servers that have not been peer-reviewed. Although preprints have existed since 1961, they have gained increased popularity during the COVID-19 pandemic due to the need for immediate, relevant information. OBJECTIVE: The aim of this study is to evaluate the publication rate and impact of preprints included in the CDC COVID-19 Science Update and assess the performance of the COVID-19 Science Update team in selecting impactful preprints. METHODS: All preprints in the first 100 editions (April 1, 2020 - July 30, 2021) of the Science Update were included in the study. Preprints that were not published were categorized as "unpublished preprints". Preprints that were subsequently published exist in two versions (in a peer-reviewed journal and on the original preprint server) which were analyzed separately and referred to as "peer-reviewed preprint" and "original preprint", respectively. Time-to-publish was the time interval between the date on which a preprint was first posted to the date on which it was first available as a peer-reviewed article. Impact was quantified by Altmetric Attention Score and citation count for all available manuscripts on August 6, 2021. Preprints were analyzed by publication status, rate, and time to publication. RESULTS: Among 275 preprints included in the CDC COVID-19 Science Update during the study period, most came from three servers: medRxiv (n=201), bioRxiv (n=41), and SSRN (n=25), with eight coming from other sources. More than half (152 of 275, 55.3%) were eventually published. The median time-to-publish was 2.31 months (IQR 1.38-3.73). When preprints posted in the last 2.31 months were excluded (to account for the time-to-publish), the publication rate was to 67.8%. Seventy-six journals published at least one preprint from the CDC COVID-19 Science Update and 18 journals published at least three. The median Altmetric Attention Score for unpublished preprints (n=123) was 146 (IQR 22-552) and median citation count of 2 (IQR 0-8); for original preprints (n=152) these values were 212 (IQR 22-1164) and 14 (IQR 2-40), respectively; for peer-review preprints, these values were 265 (IQR 29-1896) 19 (IQR 3-101), respectively. CONCLUSIONS: Prior studies of COVID-19 preprints found publication rates between 5.4% and 21.1%. Preprints included in the CDC COVID-19 Science Update were published at a higher rate than overall COVID-19 preprints, and those that were ultimately published were published within months and received higher attention scores than unpublished preprints. These findings indicate that the Science Update process for selecting preprints appears have done so with high fidelity in terms of their likelihood to be published and impactful. Incorporation of high-quality preprints into the CDC COVID-19 Science Update improves this activity's capacity to inform meaningful public health decision making.

BACKGROUND: Differentiated care strategies are rapidly becoming the norm for HIV care delivery globally. Building upon an interest in tailoring antiretroviral therapy (ART) delivery for client-centered needs, the Ministry of Health and Population in Haiti formally endorsed multiple-month dispenses (MMD) in the 2016 national ART guidelines This study explores heterogeneity in retention in care with MMD for specific Haitian populations living with HIV and evaluates if a targeted algorithm for optimal ART prescription intervals is warranted in Haiti. METHODS: This study included ART-naïve individuals who started ART on or after January 1st, 2017 in Haiti. To identify subgroups in which to explore heterogeneity of retention, we implemented a double-lasso regression method to determine which individual characteristics would define the subgroups. Characteristics evaluated for potential subgroup definition included: sex, age category, WHO clinical stage, and body mass index category. We employed instrumental variable models to estimate the causal effect of increasing ART dispensing length on ART retention, by client subgroup. The outcome of interest was retention in care after one year in treatment. We then estimated the marginal effect of a 30-day increase to ART dispensing length to retention in care for each of these subgroups. RESULTS: There was evidence for heterogeneity in the effect of extending ART dispensing intervals on retention by WHO clinical stage. We observed significant improvements to retention in care at one year with a 30-day increase in ART dispense length for all subgroups defined by WHO clinical stages 1-4. The effects ranged from a 14.7% increase (95% CI: 12.4-17.0) to the likelihood of retention for people with HIV in WHO stage 1 to a 21.6% increase (95% CI: 18.7-24.5) to the likelihood of retention for those in WHO stage 3. CONCLUSIONS: All the subgroups defined by WHO clinical stage experienced a benefit of extending ART intervals to retention in care at one year. Though the effect did differ slightly by WHO stage, the effects went in the same direction and were of similar magnitude. Therefore, a standardized recommendation for MMD among those living with HIV and new on ART is appropriate for Haiti treatment guidelines.

Background: Multi-month dispensing (MMD) for antiretroviral therapy (ART) is a promising care strategy to improve HIV treatment adherence. The effectiveness of MMD in routine settings has not yet been evaluated within a causal inference framework. We analyzed data from a robust clinical data system to evaluate MMD in Haiti. Method(s): We assessed 1-year retention in care among 21,880 ART-naive HIV-positive persons who started ART on or after January 1, 2017, up until November 1, 2018. We used an instrumental variable analysis to estimate the causal impact of MMD. This approach was used to address potential selection into specific dispensing intervals because MMD is not randomly applied to individuals. Finding(s): We found that extending ART dispensing intervals increased the probability of retention at 12 months after ART initiation, with up to a 24.2%-point increase (95%CI: 21.9, 26.5) in the likelihood of retention with extending dispenses by 30 days for those receiving one-month dispenses. We observed statistically significant gains to retention with MMD with up to an approximately 4-month supply of ART; +5.1%-points (95%CI: 2.4,7.8). Increasing dispensing lengths for those already receiving >=5-month supply of ART had a potentially negative effect on retention. Interpretation(s): MMD for ART is an effective service delivery strategy that improves care retention for new ART recipients. There is a potentially negative effect of increasing prescription lengths for those new ART recipients already receiving longer ART supplies, though more research is needed to characterize this effect given medication supplies of this length are not common for newer ART recipients.

OBJECTIVE To identify Choosing Wisely items for the American Board of Internal Medicine Foundation. METHODS The Society for Healthcare Epidemiology of America (SHEA) elicited potential items from a hospital epidemiology listserv, SHEA committee members, and a SHEA-Infectious Diseases Society of America compendium with SHEA Research Network members ranking items by Delphi method voting. The SHEA Guidelines Committee reviewed the top 10 items for appropriateness for Choosing Wisely. Five final recommendations were approved via individual member vote by committees and the SHEA Board. RESULTS Ninety-six items were proposed by 87 listserv members and 99 SHEA committee members. Top 40 items were ranked by 24 committee members and 64 of 226 SHEA Research Network members. The 5 final recommendations follow: 1. Don't continue antibiotics beyond 72 hours in hospitalized patients unless patient has clear evidence of infection. 2. Avoid invasive devices (including central venous catheters, endotracheal tubes, and urinary catheters)and, if required, use no longer than necessary. They pose a major risk for infections. 3. Don't perform urinalysis, urine culture, blood culture, or Clostridium difficile testing unless patients have signs or symptoms of infection. Tests can be falsely positive leading to overdiagnosis and overtreatment. 4. Do not use antibiotics in patients with recent C. difficile without convincing evidence of need. Antibiotics pose a high risk of C. difficile recurrence. 5. Don't continue surgical prophylactic antibiotics after the patient has left the operating room. Five runner-up recommendations are included. CONCLUSIONS These 5 SHEA Choosing Wisely and 5 runner-up items limit medical overuse. Infect Control Hosp Epidemiol 2016;37:755-760.

Evidence-based guidelines for implementation and measurement of antibiotic stewardship interventions in inpatient populations including long-term care were prepared by a multidisciplinary expert panel of the Infectious Diseases Society of America and the Society for Healthcare Epidemiology of America. The panel included clinicians and investigators representing internal medicine, emergency medicine, microbiology, critical care, surgery, epidemiology, pharmacy, and adult and pediatric infectious diseases specialties. These recommendations address the best approaches for antibiotic stewardship programs to influence the optimal use of antibiotics.

Since the publication of "A Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals" in 2008, prevention of healthcare-associated infections (HAIs) has become a national priority. Despite improvements, preventable HAIs continue to occur. The 2014 updates to the Compendium were created to provide acute care hospitals with up-to-date, practical, expert guidance to assist in prioritizing and implementing their HAI prevention efforts. They are the product of a highly collaborative effort led by the Society for Healthcare Epidemiology of America (SHEA), the Infectious Diseases Society of America (IDSA), the American Hospital Association (AHA), the Association for Professionals in Infection Control and Epidemiology (APIC), and The Joint Commission, with major contributions from representatives of a number of organizations and societies with content expertise, including the Centers for Disease Control and Prevention (CDC), the Institute for Healthcare Improvement (IHI), the Pediatric Infectious Diseases Society (PIDS), the Society for Critical Care Medicine (SCCM), the Society for Hospital Medicine (SHM), and the Surgical Infection Society (SIS).

This edition of Infection Control and Hospital Epidemiology | (ICHE) is dedicated to articles on antimicrobial stewardship. | Though such articles appear regularly in the pages of ICHE, | this is the first time that an entire issue has been devoted to | the topic. By design, this issue comes at a time of tremendous | growth in the importance of antimicrobial stewardship. The | combination of rising rates of antimicrobial resistance, a rapidly dwindling effective antimicrobial armamentarium, and | increasing financial pressures for hospitals has spurred new | interest in the one intervention that has been proven to address all these problems simultaneously. | A number of organizations have recognized the importance of implementing stewardship interventions and programs in hospitals, with major efforts being spearheaded by | the Centers for Disease Control and Prevention (CDC) and | the Society for Healthcare Epidemiology of America (SHEA). | The creation of SHEA's Antimicrobial Stewardship Taskforce | and the launch of CDC's "Get Smart for Healthcare" campaign (http://www.cdc.gov/getsmart/healfhcare) marked the | start of a new era of a nationally coordinated effort to promote inpatient antibiotic stewardship in the United States. | The growing importance and profile of antibiotic stewardship are reflected in the inclusion of several antibiotic | quality measures in the new "inpatient infection control | worksheet" currently being piloted by the Center for Medicare | and Medicaid Services (available at https://www.cms.gov/ | Surveycertificationgeninfo/downloads/SCLetter 12_01 .pdf). | The measures are not all encompassing, nor will they independently improve antibiotic use in hospitals. However, it is | hoped that they will both raise awareness of the importance | of improving antibiotic use in hospitals and help lay a foundation for accomplishing that goal.

Jointly, the Association for Professionals in Infection Control and Epidemiology (APIC), the Society for Healthcare Epidemiology of America (SHEA), the Infectious Diseases Society of America (IDSA), the Association of State and Territorial Health Officials (ASTHO), the Council of State and Territorial Epidemiologists (CSTE), Pediatric Infectious Diseases Society (PIDS), and the Centers for Disease Control and Prevention (CDC) propose a call to action to move toward the elimination of healthcare-associated infections (HAIs) by adapting the concept and plans used for the elimination of other diseases, including infections. Elimination, as defined for other infectious diseases, is the maximal reduction of “the incidence of infection caused by a specific agent in a defined geographical area as a result of deliberate efforts; continued measures to prevent reestablishment of transmission are required.” (p24) This definition has been useful for elimination efforts directed toward polio, tuberculosis, and syphilis and can be readily adapted to HAIs. Sustained elimination of HAIs can be based on this public health model of constant action and vigilance. Elimination will require the implementation of evidence-based practices, the alignment of financial incentives, the closing of knowledge gaps, and the acquisition of information to assess progress and to enable response to emerging threats. These efforts must be under-pinned by substantial research investments, the development of novel prevention tools, improved organizational and personal accountabilities, strong collaboration among a broad coalition of public and private stakeholders, and a clear national will to succeed in this arena.

A workshop in June 2005 ("Preventing Organ and Tissue Allograft-Transmitted Infection: Priorities for Public Health Intervention") identified gaps in organ and tissue safety in the US. Participants developed a series of allograft safety initiatives. "The Organ and Tissue Safety Workshop 2007: Advances and Challenges" assessed progress and identified priorities for future interventions. Awareness of the challenges of allograft-associated disease transmission has increased. The Transplantation Transmission Sentinel Network will enhance communication surrounding allograft-associated disease transmission. Other patient safety initiatives have focused on adverse event reporting and microbiologic screening technologies. Despite progress, improved recognition and prevention of donor-derived transmission events is needed. This requires systems integration across the organ and tissue transplantation communities including organ procurement organizations, eye and tissue banks, and transplant infectious disease experts. Commitment of resources and improved coordination of efforts are required to develop essential tools to enhance safety for allograft recipients.
