COVID-19 pandemic impacts on mental health, burnout, and longevity in the workplace among healthcare workers: A mixed methods study. JOURNAL OF INTERPROFESSIONAL EDUCATION & PRACTICE 2023; 32:100661. [PMID: 37305404 PMCID: PMC10248469 DOI: 10.1016/j.xjep.2023.100661] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 06/07/2023] [Indexed: 06/13/2023]
Abstract
To explore the mental health impacts of the COVID-19 pandemic on healthcare workers in Massachusetts and identify potential strategies to maintain the healthcare workforce we conducted a sequential exploratory mixed methods study. Fifty-two individuals completed interviews from April 22nd - September 7th, 2021; 209 individuals completed an online survey from February 17th - March 23rd, 2022. Interviews and surveys asked about the mental health impacts of working in healthcare during the COVID-19 pandemic, burnout, longevity in the workplace, and strategies for reducing attrition. Interview and survey participants were predominantly White (56%; 73%, respectively), female (79%; 81%) and worked as physicians (37%; 34%). Interviewees indicated high stress and anxiety levels due to frequent exposure to patient deaths from COVID-19. Among survey respondents, 55% reported worse mental health than before the pandemic, 29% reported a new/worsening mental health condition for themselves or their family, 59% reported feeling burned out at least weekly, and 37% intended to leave healthcare in less than 5 years. To decrease attrition, respondents suggested higher salaries (91%), flexible schedules (90%), and increased support to care for patients (89%). Healthcare workers' experiences with death, feeling unvalued, and overworked resulted in unprecedented rates of burnout and intention to leave healthcare.

Abstract
During the 2020-2021 academic year, schools across the country were closed for prolonged periods. Prior research suggests that children tend to gain more weight during times of extended school closures, such as summer vacation; however, little is known about the impact of school learning mode on changes. Thus, the aim of this study was to measure the association between school mode (in-person, hybrid, remote) and pediatric body mass index (BMI) percentile increases over time. In this longitudinal, statewide retrospective cohort study in Massachusetts, we found that BMI percentile increased in elementary and middle school students in all learning modes, and that increases slowed but did not reverse following the statewide reopening. Body mass percentile increases were highest in elementary school aged children. Hispanic ethnicity and receipt of Medicaid insurance were also associated with increases. Additional research is needed to identify strategies to combat pediatric body mass percentile increases and to address disparities.

Condition-Dependent and Dynamic Impacts of Indoor Masking Policies for COVID-19 Mitigation: A Nationwide, Interrupted Time-Series Analysis. Clin Infect Dis 2023:7128807. [PMID: 37072937 DOI: 10.1093/cid/ciad115] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2022] [Indexed: 04/20/2023] Open
Abstract
BACKGROUND The effectiveness and sustainability of masking policies as a pandemic control measure remain uncertain. Our aim was to evaluate different masking policy types on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) incidence and to identify factors and conditions impacting effectiveness. METHODS Nationwide, retrospective cohort study of US counties from 4/4/2020-28/6/2021. Policy impacts were estimated using interrupted time-series models with the masking policy change date (eg, recommended-to-required, no-recommendation-to-recommended, no-recommendation-to-required) modeled as the interruption. The primary outcome was change in SARS-CoV-2 incidence rate during the 12 weeks after the policy change; results were stratified by coronavirus disease 2019 (COVID-19) risk level. A secondary analysis was completed using adult vaccine availability as the policy change. RESULTS In total, N = 2954 counties were included (2304 recommended-to-required, 535 no-recommendation-to-recommended, 115 no-recommendation-to-required). Overall, indoor mask mandates were associated with 1.96 fewer cases/100 000/week (cumulative reduction of 23.52/100 000 residents during the 12 weeks after policy change). Reductions were driven by communities with critical and extreme COVID-19 risk, where masking mandated policies were associated with an absolute reduction of 5 to 13.2 cases/100 000 residents/week (cumulative reduction of 60 to 158 cases/100 000 residents over 12 weeks). Impacts in low- and moderate-risk counties were minimal (<1 case/100 000 residents/week). After vaccine availability, mask mandates were not associated with significant reductions at any risk level. CONCLUSIONS Masking policy had the greatest impact when COVID-19 risk was high and vaccine availability was low. When transmission risk decreases or vaccine availability increases, the impact was not significant regardless of mask policy type. Although often modeled as having a static impact, masking policy effectiveness may be dynamic and condition dependent.

Performance of three screening tools to predict COVID-19 positivity in emergency department patients. Emerg Med J 2023; 40:210-215. [PMID: 36596666 DOI: 10.1136/emermed-2021-212102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 12/23/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND COVID-19 symptoms vary widely. This retrospective study assessed which of three clinical screening tools-a nursing triage screen (NTS), an ED review of systems (ROS) performed by physicians and physician assistants and a standardised ED attending (ie, consultant) physician COVID-19 probability assessment (PA)-best identified patients with COVID-19 on a subsequent reverse transcription PCR (RT-PCR) confirmation. METHODS All patients admitted to Boston Medical Center from the ED between 27 April 2020 and 17 May 2020 were included. Sensitivity, specificity and positive predictive value (PPV) and negative predictive value (NPV) were calculated for each method. Logistic regression assessed each tool's performance. RESULTS The attending physician PA had higher sensitivity (0.62, 95% CI 0.53 to 0.71) than the NTS (0.46, 95% CI 0.37 to 0.56) and higher specificity (0.76, 95% CI 0.72 to 0.80) than the NTS (0.71, 95% CI 0.66 to 0.75) and ED ROS (0.62, 95% CI 0.58 to 0.67). Categorisation as moderate or high probability on the ED physician PA was associated with the highest odds of having COVID-19 in regression analyses (adjusted OR=4.61, 95% CI 3.01 to 7.06). All methods had a low PPV (ranging from 0.26 for the ED ROS to 0.40 for the attending physician PA) and a similar NPV (0.84 for both the NTS and the ED ROS, and 0.89 for the attending physician PA). CONCLUSION The ED attending PA had higher sensitivity and specificity than the other two methods, but none was accurate enough to replace a COVID-19 RT-PCR test in a clinical setting where transmission control is crucial. Therefore, we recommend universal COVID-19 testing prior to all admissions.

Healthcare workers' perspectives on the COVID-19 vaccine and boosters for themselves, their patients, and their communities: a mixed methods study. ZEITSCHRIFT FUR GESUNDHEITSWISSENSCHAFTEN = JOURNAL OF PUBLIC HEALTH 2022; 32:1-14. [PMID: 36588660 PMCID: PMC9790765 DOI: 10.1007/s10389-022-01793-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Accepted: 12/05/2022] [Indexed: 12/27/2022]
Abstract
Aim To examine experiences and attitudes of a diverse sample of clinical and non-clinical healthcare workers regarding COVID-19 vaccines and boosters for themselves, their patients, and their communities. Subject and methods We conducted a sequential exploratory mixed methods study; 52 healthcare workers participated in qualitative interviews between April 22 and September 7, 2021, and 209 healthcare workers completed surveys between February 17 and March 23, 2022. Interviews and survey questions asked about personal attitudes toward COVID-19 vaccination and boosters and experiences discussing vaccination with patients. Results Participants were predominantly White (56% and 73%, respectively) and female (79% and 81%, respectively). Factors motivating healthcare workers to take the vaccine were the belief that vaccination would protect themselves, their families, patients, and communities. Healthcare workers were accepting of and had high receipt of the booster, though some had diminished belief in its effectiveness after becoming infected with SARS-CoV-2 after initial vaccination. Race related mistrust, misinformation related to vaccine safety, and concerns about vaccine effects during pregnancy were the most common barriers that providers encountered among their patients and communities. Conclusions Healthcare workers' primary motivation to receive COVID-19 vaccines was the desire to protect themselves and others. Healthcare workers' perception was that concerns about safety and misinformation were more important barriers for their patients than themselves. Race-related medical mistrust amplified concerns about vaccine safety and hindered communication efforts.

Abstract
Healthcare workers are a trusted health information source and are uniquely positioned to reduce the burden of the COVID-19 pandemic. The purpose of this sequential exploratory mixed methods study was to understand attitudes of healthcare workers working in Massachusetts during the COVID-19 pandemic regarding strategies to improve COVID-19 vaccine utilization, including vaccine mandates and incentives. Fifty-two individuals completed one-on-one interviews between April 22nd and September 7th, 2021. The survey was developed based on findings from the interviews; 209 individuals completed the online survey between February 17th and March 23rd, 2022. Both the interview and survey asked about attitudes toward COVID-19 vaccine and booster mandates, incentives, and strategies to improve vaccination rates. Most participants were female (79%-interview, 81%-survey), Caucasian (56%, 73%), and worked as physicians (37%, 34%) or nurses (10%, 18%). Overall, nuanced attitudes regarding vaccine and booster mandates were expressed; many supported mandates to protect their patients' health, others emphasized personal autonomy, while some were against mandates if job termination was the consequence of declining vaccines. Similarly, views regarding vaccine incentives differed; some considered incentives helpful, yet many viewed them as coercive. Strategies believed to be most effective to encourage vaccination included improving accessibility to vaccination sites, addressing misinformation, discussing vaccine safety, tailored community outreach via trusted messengers, and one-on-one conversations between patients and healthcare workers. Healthcare workers' experiences with strategies to improve utilization of COVID-19 vaccines and boosters have implications for public health policies. Generally, efforts to improve access and education were viewed more favorably than incentives and mandates.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic disrupted access to and uptake of hepatitis C virus (HCV) care services in the United States. It is unknown how substantially the pandemic will impact long-term HCV-related outcomes. METHODS We used a microsimulation to estimate the 10-year impact of COVID-19 disruptions in healthcare delivery on HCV outcomes including identified infections, linkage to care, treatment initiation and completion, cirrhosis, and liver-related death. We modeled hypothetical scenarios consisting of an 18-month pandemic-related disruption in HCV care starting in March 2020 followed by varying returns to pre-pandemic rates of screening, linkage, and treatment through March 2030 and compared them to a counterfactual scenario in which there was no COVID-19 pandemic or disruptions in care. We also performed alternate scenario analyses in which the pandemic disruption lasted for 12 and 24 months. RESULTS Compared to the "no pandemic" scenario, in the scenario in which there is no return to pre-pandemic levels of HCV care delivery, we estimate 1060 fewer identified cases, 21 additional cases of cirrhosis, and 16 additional liver-related deaths per 100 000 people. Only 3% of identified cases initiate treatment and <1% achieve sustained virologic response (SVR). Compared to "no pandemic," the best-case scenario in which an 18-month care disruption is followed by a return to pre-pandemic levels, we estimated a smaller proportion of infections identified and achieving SVR. CONCLUSIONS A recommitment to the HCV epidemic in the United States that involves additional resources coupled with aggressive efforts to screen, link, and treat people with HCV is needed to overcome the COVID-19-related disruptions.

Abstract
BACKGROUND AND OBJECTIVES Mandatory quarantine upon exposure to coronavirus disease 2019 (COVID-19) results in a substantial number of lost days of school. We hypothesized that implementation of a state-wide test-to-stay (TTS) program would allow more students to participate in in-person learning, and not cause additional clusters of COVID-19 cases due to in-school transmission. METHODS For the 2020-2021 academic year, Massachusetts implemented an opt-in TTS program, in which students exposed to COVID-19 in school are tested each school day with a rapid antigen test. If negative, students may participate in school-related activities that day. Testing occurs daily for a duration of 7 calendar days after exposure. Here, we report the results from the first 13 weeks of the program. RESULTS A total of 2298 schools signed up for TTS, and 504 167 individuals out of a total population of 860 457 consented. During the first 13 weeks with complete data, 1959 schools activated the program at least once for 102 373 individual, exposed students. Out of 328 271 tests performed, 2943 positive cases were identified (per person positivity rate, 2.9%, 95% confidence interval, 2.8-3.0). A minimum of 325 328 and a maximum of 497 150 days of in-person school were saved through participation in the program. CONCLUSIONS Daily, rapid on-site antigen testing is a safe and feasible alternative to mandatory quarantine and can be used to maximize safe in-person learning time during the pandemic.

Abstract
Objectives: Emergency departments (EDs) could play an important role in the COVID-19 pandemic response by reaching patients who would otherwise not seek vaccination in the community. Prior to expanding COVID-19 vaccination to the acute care setting, we assessed ED patients’ COVID-19 vaccine status, perspectives, and hypothetical receptivity to ED-based vaccination. Methods: From January 11 through March 31, 2021, we conducted a multisite (Albany Medical Center, Boston Medical Center, Buffalo General Hospital, University of Cincinnati Medical Center, and Upstate Medical Center), cross-sectional survey of ED patients, with embedded randomization for participants to receive 1 of 4 vignette vaccination messages (simple opt-in message, recommendation by the hospital, community-oriented message, and acknowledgment of vaccine hesitancy). Main outcomes included COVID-19 vaccination status, prior intention to be vaccinated, and receptivity to randomized hypothetical vignette messages. Results: Of 610 participants, 122 (20.0%) were vaccinated, 234 (38.4%) had prior intent to be vaccinated, 111 (18.2%) were unsure as to prior intent, and 143 (23.4%) had no prior intent to be vaccinated. Vaccine hesitancy (participants who were vaccine unsure or did not intend to receive the vaccine) was associated with the following: age <45 years, female, non-Hispanic Black, no primary health care, and no prior influenza vaccination. Overall, 364 of 565 (64.4%; 95% CI, 60.3%-68.4%) were willing to accept a hypothetical vaccination in the ED. Among participants with prior vaccine hesitancy, a simple opt-in message resulted in the highest acceptance rates to hypothetical vaccination (39.7%; 95% CI, 27.6%-52.8%). Conclusions: EDs have appropriate patient populations to initiate COVID-19 vaccination programs as a supplement to community efforts. A simple opt-in approach may offer the best messaging to reach vaccine-hesitant ED patients.

Abstract
There are limited tools for adapting coronavirus disease 2019 (COVID-19) infection control plans to school settings. We present an infection prevention model for optimizing safe re-opening for elementary and secondary schools during the global COVID-19 pandemic and review the current evidence behind various infection prevention interventions in school settings. The model is adapted from the Centers for Disease Control and Prevention fundamental pillars for infection prevention and includes 4 categories of intervention: epidemiologic controls (town prevalence metrics, diagnostic testing, quarantine strategies), administrative controls (state vaccination policies, alternative school models, symptom screens, quarantine breaks), engineering/environmental controls (distancing, outdoor space, ventilation), and personal protective equipment (PPE)/hand hygiene (face coverings, hand sanitizing). The adapted infection control pillars model utilizes implementation science–informed considerations to maximize pragmatism and adherence by leveraging evidence-based strategies. It highlights the necessity of redundant infection prevention interventions, acknowledges the importance of community buy-in to achieve real-world effectiveness, and addresses tactics to overcome implementation barriers. Recommendations are grounded in the Dynamic Sustainability Framework and include suggestions to maintain infection prevention effectiveness over time to ensure ongoing safety.

A pilot model of a public-private partnership for implementation of a coronavirus disease 2019 (COVID-19) diagnostic testing program to facilitate a safe school reopening. ANTIMICROBIAL STEWARDSHIP & HEALTHCARE EPIDEMIOLOGY : ASHE 2022; 2:e4. [PMID: 36310804 PMCID: PMC9614916 DOI: 10.1017/ash.2021.249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Revised: 11/22/2021] [Accepted: 11/24/2021] [Indexed: 06/16/2023]
Abstract
OBJECTIVE We developed an implementation plan to integrate diagnostic testing for coronavirus disease 2019 (COVID-19) into a public school system. Implementation barriers were identified and strategies were mapped to overcome them. DESIGN A COVID-19 diagnostic testing program leveraging a public-private partnership was developed for a public school system. SETTING A suburban school district and a local hospital during the 2020-2021 academic year. METHODS Using Consolidated Framework for Implementation Research (CFIR) constructs and evidenced-based implementation strategies, the program was designed as a "closed system" and was adapted based on stakeholder feedback. Implementation barriers and facilitators were identified and mapped to CFIR constructs to provide insights into factors influencing program adoption. RESULTS Preimplementation stages of engagement, feasibility, and readiness planning were completed. The program did not progress to implementation due to multiple factors, including changes in school leadership (inner setting and process-level constructs), improved access to outside testing, and lack of an existing paradigm for in-school testing (external constructs). Limited support from key stakeholders and opinion leaders was also a barrier (process-level construct). CONCLUSIONS Although this locally initiated program did not progress beyond the preimplementation stage, the processes developed and barriers identified may be useful to inform planning efforts in other testing programs within public school systems. Future programs may consider incorporating multiplex diagnostic testing for influenza in addition to COVID-19. With relaxation of infection control measures, the prevalence of other respiratory viruses will increase. Actionable results will be needed to inform decisions about closures and quarantines.

Abstract
INTRODUCTION Influenza vaccination is a recommended tool in preventing influenza-related illnesses, medical visits, and hospitalizations. With many patients remaining unvaccinated each year, the Emergency Department (ED) represents a unique opportunity to provide vaccinations to patient not yet vaccinated. However, busy urban safety-net EDs maybe challenged to safely execute such a vaccination program. The aim of this quality improvement project was to assess influenza vaccination feasibility in the ED and improve influenza vaccination rates in our community. METHODS The quality improvement work-group, comprised of ED physicians, nurses, and pharmacists, designed and implemented an influenza vaccination protocol that aligned with the ED workflow. The outcome measure was the total number of patients vaccinated per month and per influenza season. Process measures included the type of influenza vaccine administered and type of care area within ED. Balancing measures were also included. RESULTS Following the initiative, a total of 337 patients received influenza vaccinations in the ED between September 1, 2018 and December 31, 2020 compared to none during the previous influenza season. With each influenza season, the number of vaccinated patients increased from 61 to 134 and 142, respectively. The average age of the patients was 48.23 ± 15.29, 52.89 ± 15.91, and 44.92 ± 18.97 years old. Most patients received the vaccination while roomed in the high acuity section of the adult ED. No adverse effects or automated dispensing cabinet stockouts were observed. CONCLUSION Our structured program indicates that influenza vaccine administration to eligible patients is feasible in a busy urban safety-net ED. Piloting new and further developing existing ED-based influenza vaccination programs have the potential to significantly benefit public health.

Abstract
The role that traditional and hybrid in-person schooling modes contribute to the community incidence of SARS-CoV-2 infections relative to fully remote schooling is unknown. We conducted an event study using a retrospective nationwide cohort evaluating the effect of school mode on SARS-CoV-2 cases during the 12 weeks after school opening (July-September 2020, before the Delta variant was predominant), stratified by US Census region. After controlling for case rate trends before school start, state-level mitigation measures and community activity level, SARS-CoV-2 incidence rates were not statistically different in counties with in-person learning versus remote school modes in most regions of the United States. In the South, there was a significant and sustained increase in cases per week among counties that opened in a hybrid or traditional mode versus remote, with weekly effects ranging from 9.8 (95% confidence interval (CI) = 2.7-16.1) to 21.3 (95% CI = 9.9-32.7) additional cases per 100,000 persons, driven by increasing cases among 0-9 year olds and adults. Schools can reopen for in-person learning without substantially increasing community case rates of SARS-CoV-2; however, the impacts are variable. Additional studies are needed to elucidate the underlying reasons for the observed regional differences more fully.

Abstract
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.

Seroprevalence of SARS-CoV-2 IgG antibodies and risk factors in health care workers at an academic medical center in Boston, Massachusetts. Sci Rep 2021; 11:9694. [PMID: 33958668 PMCID: PMC8102593 DOI: 10.1038/s41598-021-89107-5] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Accepted: 04/20/2021] [Indexed: 12/24/2022] Open
Abstract
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.

Abstract
Background COVID-19 vaccine trials and post-implementation data suggest vaccination decreases SARS-CoV-2 infections. We examine COVID-19 vaccination's impact on SARS-CoV-2 case rates and viral diversity among healthcare workers (HCW) during a high community prevalence period. Methods A prospective cohort study from Boston Medical Center (BMC)'s HCW vaccination program, where staff received two doses of BNT162b2 or mRNA-1273. We included PCR-confirmed SARS-CoV-2 cases among HCWs from December 09, 2020 to February 23, 2021. Weekly SARS-CoV-2 rates per 100,000 person-day overall and by time from first injection (1-14 and >14 days) were compared with surrounding community rates. Viral genomes were sequenced from SARS CoV-2 positive samples. 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 SARS-CoV-2 infection rate ratios were 0.73 (95% CI 0.53-1.00) 1-14 days and 0.18 (0.10-0.32) >14 days from first dose. HCW SARS-CoV-2 cases >14 days from initial dose compared to within 14 days were more often older (46 versus 38 years, p=0.007), Latinx (10% versus 8%, p=0.03), and asymptomatic (48% versus 11%, p=0.0002). SARS-CoV-2 rates among HCWs fell below those of the surrounding community, with a 18% versus 11% weekly decrease respectively (p=0.14). Comparison of 48 SARS-CoV-2 genomes sequenced from post-first dose cases did not indicate selection pressure towards known spike-antibody escape mutations. Conclusions Our results indicate a positive impact of COVID-19 vaccines on SARS-CoV-2 case rates. Post-vaccination isolates did not show unusual genetic diversity or selection for mutations of concern. Main Point Cases of SARS-CoV-2 among health care workers dropped rapidly with COVID-19 vaccination. Sequencing 48 breakthrough infections (overwhelmingly in 14 days after 1st dose) showed no clear sign of any differences in spike protein compared with time-matched, unvaccinated control sequences.

Effectiveness of three versus six feet of physical distancing for controlling spread of COVID-19 among primary and secondary students and staff: A retrospective, state-wide cohort study. Clin Infect Dis 2021; 73:1871-1878. [PMID: 33704422 PMCID: PMC7989511 DOI: 10.1093/cid/ciab230] [Citation(s) in RCA: 37] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Indexed: 11/18/2022] Open
Abstract
Background National and international guidelines differ about the optimal physical distancing between students for prevention of SARS-CoV-2 transmission; studies directly comparing the impact of ≥3 versus ≥6 feet of physical distancing policies in school settings are lacking. Thus, our objective was to compare incident cases of SARS-CoV-2 in students and staff in Massachusetts public schools among districts with different physical distancing requirements. State guidance mandates masking for all school staff and for students in grades 2 and higher; the majority of districts required universal masking. Methods Community incidence rates of SARS-CoV-2, SARS-CoV-2 cases among students in grades K-12 and staff participating in-person learning, and district infection control plans were linked. Incidence rate ratios (IRR) for students and staff members in districts with ≥3 versus ≥6 feet of physical distancing were estimated using log-binomial regression; models adjusted for community incidence are also reported. Results Among 251 eligible school districts, 537,336 students and 99,390 staff attended in-person instruction during the 16-week study period, representing 6,400,175 student learning weeks and 1,342,574 staff learning weeks. Student case rates were similar in the 242 districts with ≥3 feet versus ≥6 feet of physical distancing between students (IRR, 0.891, 95% CI, 0.594-1.335); results were similar after adjusting for community incidence (adjusted IRR, 0.904, 95% CI, 0.616-1.325). Cases among school staff in districts with ≥3 feet versus ≥6 feet of physical distancing were also similar (IRR, 1.015, 95% CI, 0.754-1.365). Conclusions Lower physical distancing policies can be adopted in school settings with masking mandates without negatively impacting student or staff safety.

Abstract
Introduction: Coronavirus disease 2019 (COVID-19) has led to unprecedented modifications to
healthcare delivery in the U.S. To preserve resources in preparation for a
COVID-19 surge, Boston Medical Center (BMC) implemented workflows to
decrease ambulatory in-person visits effective March 16th, 2020.
Telemedicine was incorporated into clinical workflows and much preventive
care, including Hepatitis C (HCV) testing, was not routinely performed. Objective: To explore the impact that the COVID-19 rapid restructuring response has had
on HCV testing and identification hospital-wide and in ambulatory
settings. Methods: BMC utilizes reflex confirmatory testing for HCV. When a sample is HCV Ab
positive, it is automatically reflexed for confirmatory RNA and genotype
testing. HCV test results for patients were collected daily. We compared
unique patient tests for 3.5 month periods before and after March 16th,
2020. Descriptive statistics showed total tests and total new HCV RNA+
before versus after, both hospital-wide and in ambulatory clinics alone.
Mean daily tests completed were compared. Results: Hospital-wide, total HCV testing decreased by 49.6%, and new HCV+ patient
identification decreased by 42.1%. In ambulatory clinics, testing decreased
by 71.9%, and new HCV+ identification decreased by 63.3%. Hospital-wide,
mean daily tests decreased by 22.9 tests per day (95% CI: 17.9-28.0,
P < .001), and mean daily new HCV+ identification
decreased by 0.36 (95% CI: 0.20-0.53, P < .001). In
ambulatory clinics, mean daily tests decreased by 22.1 tests per day (95%
CI: 17.5-26.7, P < .001) and mean daily HCV+ decreased
by 1.40 (95% CI: 1.03-1.76, P < .001). Conclusion: The COVID-19 systematic emergency response led to decreased HCV testing and
identification, and in this regard telemedicine acts as a barrier to HCV
care. Other public health initiatives must be monitored in the context of
telemedicine workflows. Continued monitoring of HCV screening trends is
vital, and adaptive approaches to work toward the goal of HCV elimination
are needed.

Point-of-care Lung Ultrasound Is More Sensitive than Chest Radiograph for Evaluation of COVID-19. West J Emerg Med 2020; 21:771-778. [PMID: 32726240 PMCID: PMC7390587 DOI: 10.5811/westjem.2020.5.47743] [Citation(s) in RCA: 46] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2020] [Revised: 06/01/2020] [Accepted: 05/30/2020] [Indexed: 01/01/2023] Open
Abstract
INTRODUCTION Current recommendations for diagnostic imaging for moderately to severely ill patients with suspected coronavirus disease 2019 (COVID-19) include chest radiograph (CXR). Our primary objective was to determine whether lung ultrasound (LUS) B-lines, when excluding patients with alternative etiologies for B-lines, are more sensitive for the associated diagnosis of COVID-19 than CXR. METHODS This was a retrospective cohort study of all patients who presented to a single, academic emergency department in the United States between March 20 and April 6, 2020, and received LUS, CXR, and viral testing for COVID-19 as part of their diagnostic evaluation. The primary objective was to estimate the test characteristics of both LUS B-lines and CXR for the associated diagnosis of COVID-19. Our secondary objective was to evaluate the proportion of patients with COVID-19 that have secondary LUS findings of pleural abnormalities and subpleural consolidations. RESULTS We identified 43 patients who underwent both LUS and CXR and were tested for COVID-19. Of these, 27/43 (63%) tested positive. LUS was more sensitive (88.9%, 95% confidence interval (CI), 71.1-97.0) for the associated diagnosis of COVID-19 than CXR (51.9%, 95% CI, 34.0-69.3; p = 0.013). LUS and CXR specificity were 56.3% (95% CI, 33.2-76.9) and 75.0% (95% CI, 50.0-90.3), respectively (p = 0.453). Secondary LUS findings of patients with COVID-19 demonstrated 21/27 (77.8%) had pleural abnormalities and 10/27 (37%) had subpleural consolidations. CONCLUSION Among patients who underwent LUS and CXR, LUS was found to have a higher sensitivity than CXR for the evaluation of COVID-19. This data could have important implications as an aid in the diagnostic evaluation of COVID-19, particularly where viral testing is not available or restricted. If generalizable, future directions would include defining how to incorporate LUS into clinical management and its role in screening lower-risk populations.

False Elevation of Volume Determined by Bladder Scanner Secondary to Bowel Obstruction. Clin Pract Cases Emerg Med 2020; 4:158-160.

Abstract
Bladder scanners allow for quick determination of bladder volumes (BV) with minimal training. BV measured by a machine is generally accurate; however, circumstances exist in which falsely elevated BVs are reported. This case details a patient with a significant small bowel obstruction (SBO) due to superior mesenteric artery syndrome causing a falsely elevated BV. We believe this is the first case report of a SBO causing an elevated BV by bladder scanner. Emergency physicians should be aware of the pitfalls of using bladder scanners, and use their point-of-care ultrasound skills when possible to expand their differential.

Abstract
Background It is unclear whether sites that screen large numbers of patients for Hepatitis C Virus but achieve limited follow-up are more or less effective at having patients succeed through linkage and treatment than lower volume sites that have higher linkage percentages. The objective was to compare the rates of HCV identification, linkage to care, and treatment success between different study sites including the Emergency Department, 3 outpatient clinics with unique patients, and the inpatient setting at one medical center Methods This is a descriptive analysis of 2 years of data from a protocol that integrated HCV screening and treatment into clinical services throughout multiple departments in one medical center. The program used a best practice advisory to prompt testing at all sites, with different triggers for it to fire at each site, and one central navigation program that attempted to link all patients diagnosed with hepatitis C virus to outpatient care. Outcomes included volume of tests performed in each site, Antibody and RNA rates at each site, demographic data, navigation and linkage outcomes, and post-linkage treatment completion. Results 28,435 patients were screened across 5 clinical locations. RNA+ rates and absolute numbers linked to MD (linkage rates among all RNA+) were: ED 7.2% RNA+, 224 (22.6%) linked; Inpatient 14.8% RNA+, 27 (17.6%) linked, General Internal Medicine 3.9% RNA+, 269 (65.8%) linked, Infectious Diseases 4.0% RNA+, 34(70.8%) linked, Family Medicine 2.0% RNA+, 28 (75.7%) linked. Demographics, linkage barriers, and treatment initiation rates were different at all sites. Conclusion Among sites there were differences in the sociodemographic characteristics of patients diagnosed with HCV, as well as differences in the success linking patients to outpatient care. At this medical center, the ED screened the most patients, the inpatient area had the highest RNA positivity rate, the FM clinic had the highest linkage rate, GIM linked the most patients by absolute number, and GIM also had the highest number of patients start treatment.

Abstract
INTRODUCTION Availability of anti-viral agents and need to isolate infected patients increases the need to confirm the diagnosis of influenza before determining patient disposition. OBJECTIVES We sought to determine if time-to-disposition (TTD) was shorter among patients tested for influenza using an Emergency Department (ED) Point-of-care (POC) test compared to core laboratory (lab) test and to determine difference in antibiotic use between groups. METHODS We prospectively enrolled a convenience sample of ED patients for whom influenza testing was ordered during influenza season 2017. Participants were randomized to POC or lab. Data collected included demographics, chief complaint, influenza test results, turnaround time (TAT), whether antibiotics were given, and TTD. Descriptive statistics were calculated and group comparisons conducted using chi squared and Wilcoxon Rank Sum tests. RESULTS Study population included 100 in the POC group and 97 in the lab group. Demographics were similar between POC and lab participants. More flu positive results were reported in the POC group compared to the lab group (51.0% vs. 33.0% p = 0.01). The median TTD was 146.5 min (IQR 98.5) for POC group and 165.5 min (IQR 127) for lab group (p = 0.26). The median TAT was 30.5 min (IQR 7.5) for POC group and 106.0 min (IQR 55) for core lab group (p = 0.001). Antibiotics were given to 14.0% of POC participants and 14.4% of lab participants (p = 0.93). CONCLUSIONS Although use of a POC influenza test provided more rapid TAT than use of a core lab test, there was no significant difference in TTD or antibiotic use between groups.

Abstract
Point of Care Testing (POCT) provides the capability for rapid laboratory test results in patient care environments where a traditional clinical laboratory is not available. POCTs have shorter turn-around times (TATs), they may be performed by non-laboratory personnel, and the need for transport time is eliminated. The Food and Drug Administration (FDA) recently granted Clinical Laboratory Improvements Amendment (CLIA) waiver status to the cobas® Influenza A/B & RSV assay, a rapid, accurate point-of-care test for Influenza and respiratory syncytial virus (RSV) performed on the Liat® System. The performance characteristics of this test were determined though a multi-site study consisting of different point of care testing environments. Prospectively collected Nasopharyngeal (NP) swabs from 1361 patients seen at 8 primary care clinics and 4 emergency departments (EDs) and 295 retrospectively identified specimens were tested for Influenza A/B and RSV on the cobas® Liat® platform. Performance characteristics were determined through comparison to ProFlu+, a laboratory-based PCR test for Influenza A/B and RSV (reference test). Discordant specimens were adjudicated following bi-directional sequencing. The cobas® Influenza A/B and RSV assay showed sensitivities of 99.6%, 99.3%, and 96.8% for Influenza A, Influenza B, and RSV, respectively as determined from percent positive agreement (PPA) following comparison to the reference test. Sequencing confirmed cobas® Influenza A/B and RSV results in 49.2% of reference test discordant specimens, while crossing threshold data suggest increased sensitivity compared to the reference test. The cobas® Influenza A/B and RSV assay was found to be a rapid, sensitive POCT for the detection of these viruses, and provides laboratory-quality PCR-based diagnostic results in point of care settings.

Abstract
Severe hyperkalemia (serum potassium N 7.0 mmol/L) is an uncommon electrolyte abnormality in patients undergoing maintenance peritoneal dialysis (PD). Hemodialysis (HD) has been suggested as the definitive therapy for severe hyperkalemia in this population,although there is limited data regarding renal replacement options.We report a case of life-threatening hyperkalemia with electrocardiogram changes in a nonadherent PD patient who was successfully treated with standard medical therapy and manual exchanges initiated by emergency department (ED) personnel. The patient did not require HD. This case demonstrates the potential utility of PD as a treatment option for severe hyperkalemia in established dialysis patients when EDs are prepared to deliver exchanges. This report maybe particularly relevant due to the increasing prevalence rate of PD and for centers with limited HD access.

Abstract
Background With the recent growth of fellowships in international emergency medicine, the authors sought to evaluate medical students’ attitudes toward international emergency medicine and to determine the effects these attitudes have on their residency selection. Methods Study design: Cross-sectional survey. Data collection: An anonymous, eight-question online survey was distributed to all members of the American Academy of Emergency Medicine Resident and Student section. This survey was also distributed to fourth-year medical students rotating through the Emergency Department at Los Angeles County and the University of Southern California. Results Ninety-eight surveys were collected, 61 from rotating students and 37 from the AAEM mailing. There were no statistically significant differences in responses between the two groups. Of the respondents, 49.4% of have been exposed to IEM, and 46.9% have participated in international health projects. Ninety-four percent agree that IEM is an exciting career option. Seventy-nine percent said programs with IEM opportunities are more appealing than those without, and 45% said the presence of IEM opportunities would be an important factor in rank list; 53% believe that IEM requires formal public health training, and 63% believe it requires tropical medicine training; 68.3%of respondents speak a language in addition to English. This subset was more likely to have participated in IEM projects previously (p = 0.026) but not more likely to make match choices based on IEM. Conclusions Half of medical students surveyed had prior experience in international health, and most agree that international emergency medicine is an exciting career option. Over two thirds believe that the presence of IEM opportunities will be a factor in their match list decision.

Abstract
STUDY OBJECTIVE Methicillin-resistant Staphylococcus aureus (MRSA) is one of the most common causes of skin and soft tissue infections in patients presenting to the emergency department (ED). The prevalence of asymptomatic MRSA colonization in ED patients is less well described, particularly in the absence of a skin and soft tissue infection-related complaint. The goals of this study are to assess the prevalence of nasal and extranasal staphylococcal colonization in ED patients, evaluate risk factors, and molecularly characterize the strains. METHODS We performed active surveillance for methicillin-susceptible S aureus (MSSA) and MRSA colonization in 400 subjects presenting to an urban ED. Risk factor assessment was performed and culture testing was conducted on anterior nares, oropharynx, palms, groin, perirectal area, wounds, and catheter insertion sites. Multiplex polymerase chain reaction was used to identify the USA300/400 clonal types. RESULTS The prevalence of colonization with MSSA was 39% (95% confidence interval 34.2% to 44.0%), and prevalence of colonization with MRSA was 5% (95% confidence interval 3.1% to 7.6%). Among MRSA-colonized subjects, an extranasal site tested positive in 80% of subjects, and 45% had exclusive extranasal colonization. USA300 was identified in 55% of MRSA-colonized subjects. The main risk factors for MRSA colonization included HIV infection, diabetes, and participation in contact sports. CONCLUSION The overall prevalence of MRSA colonization in this ED population was lower than that reported in other high-risk ambulatory care settings. However, extranasal colonization was present in more than half of MRSA-colonized subjects, and USA300 was the predominant clonal type.
