BACKGROUND: Nearly a year after COVID-19 was initially detected, guidance for pregnant and new mothers remains varied. OBJECTIVE: The goal of this systematic review is to summarize recommendations for three areas of maternal and fetal care-breastfeeding, post-partum social distancing, and decontamination. SEARCH STRATEGY: We searched PubMed, Embase and Web of Science spanning from inception to November 9, 2020. SELECTION CRITERIA: Articles were included if they focused on COVID-positive mothers, commented on at least one of the three areas of interest, and were published in English. DATA COLLECTION AND ANALYSIS: Our combined database search yielded 385 articles. After removing duplicates and articles that did not cover the correct populations or subject matter, a total of 74 articles remained in our analysis. MAIN RESULTS: Most articles recommended direct breastfeeding with enhanced precaution measures. Recommendations regarding post-partum social distancing varied, although articles published more recently often recommended keeping the mother and newborn in the same room when possible. Decontamination recommendations emphasized mask wearing, good hand hygiene, and proper cleaning of surfaces. CONCLUSION: In general, there was a focus on shared decision making when approaching topics such as breastfeeding and post-partum social distancing. Guidelines for decontamination were fairly uniform.

Introduction Sepsis is the leading cause of infectious morbidity and mortality among hospitalized neonates. In high-resource pediatric and adult intensive care units, use of aqueous chlorhexidine (CHG) solution has been associated with reduced risk of bloodstream infections (BSI). Objectives To assess the impact of bathing of neonates with 2% CHG on BSI, suspected sepsis, and mortality in a low-income country neonatal care unit. Methods We conducted a secondary analysis of data from the Sepsis Prevention in Neonates in Zambia (SPINZ) study, a prospective observational cohort study performed at a large public referral hospital in Lusaka, Zambia. The SPINZ study assessed the impact of an infection control bundle (consisting of alcohol hand rub, SMS hygiene reminders, enhanced environmental cleaning, and CHG baths for babies ≥1.5 kg) on sepsis, BSI, and all-cause mortality. Episodic shortages in study staffing resulted in some enrolled babies not receiving a CHG bath. Using Longitudinal Targeted Maximum Likelihood Estimation and Cox proportional hazards regression to adjust for observed confounding, we estimated the causal effect of receiving a CHG bath within the first 3 days of life on suspected sepsis, BSI, and death among inborn babies enrolled during the study implementation and intervention phases. Results The majority of inborn, enrolled babies ≥1.5 kg received a CHG bath within 3 days of NICU admission (864 of 1233, 70%). We found that CHG bathing reduced the hazard rate of BSI among inborn babies ≥1.5 kg by a factor of 0.58 (p = 0.10, 95% CI: 0.31, 1.11), corresponding to an absolute risk reduction of 9.6 percentage points within a week of admission (p = 0.002, 95% CI: 3.4–15.7 percentage points). We did not find a statistically significant effect of CHG bathing on culture-negative sepsis (p = 0.54) or death (p = 0.85). Conclusion In our single center study, CHG bathing at admission was associated with a reduced risk of BSI due to a pathogenic organism after adjusting for potential confounding. Our results suggest that CHG may be an effective intervention for preventing neonatal sepsis in high-risk, low-income country settings.

Background Coronavirus disease 2019 (COVID-19) vaccine trials and post-implementation data suggest that vaccination decreases infections. We examine vaccination’s impact on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) case rates and viral diversity among health care workers (HCWs) during a high community prevalence period. Methods In this prospective cohort study, HCW received 2 doses of BNT162b2 or mRNA-1273. We included confirmed cases among HCWs from 9 December 2020 to 23 February 2021. Weekly SARS-CoV-2 rates per 100,000 person-days and by time from first injection (1–14 and ≥15 days) were compared with surrounding community rates. Viral genomes were sequenced. Results SARS-CoV-2 cases occurred in 1.4% (96/7109) of HCWs given at least a first dose and 0.3% (17/5913) of HCWs given both vaccine doses. Adjusted rate ratios (95% confidence intervals) were 0.73 (.53–1.00) 1–14 days and 0.18 (.10–.32) ≥15 days from first dose. HCW ≥15 days from initial dose compared to 1-14 days were more often older (46 vs 38 years, P = .007), Latinx (10% vs 8%, P = .03), and asymptomatic (48% vs 11%, P = .0002). SARS-CoV-2 rates among HCWs fell below the surrounding community, an 18% vs 11% weekly decrease, respectively (P = .14). Comparison of 50 genomes from post–first dose cases did not indicate selection pressure toward known spike antibody escape mutations. Conclusions Our results indicate an early positive impact of vaccines on SARS-CoV-2 case rates. Post-vaccination isolates did not show unusual genetic diversity or selection for mutations of concern.

Background Sepsis is a leading cause of neonatal mortality in low-resource settings. As facility-based births become more common, the proportion of neonatal deaths due to hospital-onset sepsis has increased. Methods We conducted a prospective cohort study in a neonatal intensive care unit in Zambia where we implemented a multifaceted infection prevention and control (IPC) bundle consisting of IPC training, text message reminders, alcohol hand rub, enhanced environmental cleaning, and weekly bathing of babies ≥1.5 kg with 2% chlorhexidine gluconate. Hospital-associated sepsis, bloodstream infection (BSI), and mortality (>3 days after admission) outcome data were collected for 6 months prior to and 11 months after bundle implementation. Results Most enrolled neonates had a birth weight ≥1.5 kg (2131/2669 [79.8%]). Hospital-associated mortality was lower during the intervention than baseline period (18.0% vs 23.6%, respectively). Total mortality was lower in the intervention than prior periods. Half of enrolled neonates (50.4%) had suspected sepsis; 40.8% of cultures were positive. Most positive blood cultures yielded a pathogen (409/549 [74.5%]), predominantly Klebsiella pneumoniae (289/409 [70.1%]). The monthly rate and incidence density rate of suspected sepsis were lower in the intervention period for all birth weight categories, except babies weighing Conclusions A simple IPC bundle can reduce sepsis and death in neonates hospitalized in high-risk, low-resource settings. Further research is needed to validate these findings in similar settings and to identify optimal implementation strategies for improvement and sustainability.

Massachusetts is one of the epicenters of the opioid epidemic and has been severely impacted by injection-related viral and bacterial infections. A recent increase in newly diagnosed human immunodeficiency virus (HIV) infections among persons who inject drugs in the state highlights the urgent need to address and bridge the overlapping epidemics of opioid use disorder (OUD) and injection-related infections. Building on an established relationship between the Massachusetts Department of Public Health and Boston Medical Center, the Infectious Diseases section has contributed to the development and implementation of a cohesive response involving ambulatory, inpatient, emergency department, and community-based services. We describe this comprehensive approach including the rapid delivery of antimicrobials for the prevention and treatment of HIV, sexually transmitted diseases, systemic infections such as endocarditis, bone and joint infections, as well as curative therapy for chronic hepatitis C virus in a manner that is accessible to patients on the addiction-recovery continuum. We also provide an overview of programs that provide access to medications for OUD, harm reduction services including overdose education, and distribution of naloxone. Finally, we outline lessons learned to inform initiatives in other settings., A partnership between Boston Medical Center and the Massachusetts Department of Public Health has informed the development and implementation of comprehensive programs across medical settings to address injection-related infections and substance use disorder.

Healthcare workers (HCWs) are at an increased risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel virus that causes Coronavirus Disease (COVID-19). We aim to assess the seroprevalence of SARS-CoV-2 IgG among healthcare workers and compare risk-factors between seropositive and seronegative HCWs. In this observational study, serum samples were collected from HCWs between July 13th to 26th, 2020 at Boston Medical Center (BMC). Samples were subsequently tested for SARS-CoV-2 IgG antibody using the Abbott SARS-CoV-2 IgG assay. Participants also answered a questionnaire capturing data on demographics, history of COVID-19 symptoms, occupation, infection prevention and control measures. Overall, 95 of 1743 (5.5%) participants tested positive for SARS-CoV-2 IgG. Of these, 1.8% of the participants had mild or no COVID-19 symptoms and did not require a diagnostic test. Seropositivity was not associated with gender, occupation, hand hygiene and personal protective equipment (PPE) practices amongst HCWs. However, lack of physical distancing among health care workers in work areas and break room was associated with seropositivity (p = 0.05, p = 0.003, respectively). The majority of the HCWs are negative for SARS-CoV-2 IgG. This data highlights the need to promote infection prevention measures, and the importance of distance amongst co-workers to help mitigate infection rates.

Expatriates comprise a diverse set of travelers who face unique medical, psychiatric, and non-health-related risks as a result of increased exposure to host country environment and associated lifestyle. Expatriates have an increased risk of developing malaria, gastrointestinal disorders, latent tuberculosis, vaccine-preventable infections, and psychological disorders, when compared with other travelers, yet the majority of existing pretravel guidelines have been designed to suit the needs of nonexpatriates. Although greater interest in expatriate health issues has led to improved characterization of illness in this population, expatriate-specific risk mitigation strategies—including modifications to chemoprophylaxis recommendations, limiting tuberculosis exposure, and prevention of occupational or sexual blood-borne virus transmission—are poorly described. Occupations and destinations affect travel-related disease risk and should inform the pretravel consultation.

Background Clostridium difficile infections (CDI) are the leading cause of health care-associated diarrhea, and is reported to cause 500,000 patient infections in the United States per year. A target for reducing the number of CDIs have been established by the Centers for Medicare and Medicaid Services (CMS). Boston Medical Center9s reported CY2013 Standardized Infection Ration (SIR) for Hospital Onset CDI was 1.573, above the US National Benchmark of 1. Objectives Reduce the SIR Hospital Onset C. difficile to CMS expected ratio of =1 by June, 2016. Methods Using Quality Improvement methodologies a multidisciplinary team addressed the appropriateness of CDI PCR testing and increased patient isolation through the use of the electronic medical record. PDSAs included: The CDI order was modified to include instructions on appropriate test frequency and sample consistency. Past lab results are displayed within the order as an automated reminder. A Best Practice Alert “fires” when writing an order if a laxative has been administered within the past 72 hours, recommending that the laxative is discontinued prior to testing Created a CDI testing and Contact Plus Isolation order panel to reduce the risk of environmental contamination. Negative lab results include instructions to discontinue isolation. Results Decreased test volume by 39%; reduced inappropriate repeat testing by 80%, 7 day negative and 66%, 30 day positive. Achieved SIR 4 quarter average 0.78, better than national goal. Conclusions Through the use of QI and leveraging changes in the eMAR improves appropriate testing and patient isolation reducing the risk of hospital acquired CDI.
