Objectives Influenza infects millions of people each year and contributes to tens of thousands of deaths annually despite the availability of vaccines. People most at risk of influenza complications are disproportionately represented in people incarcerated in US prisons and jails. The objectives of this study were to survey health administrators in Massachusetts county jails about institutional influenza vaccine policies and practices and estimate influenza vaccination rates in Massachusetts jails from 2013 to 2020. Methods In April 2020, we administered surveys to the health services administrators in Massachusetts’ 14 county jails to gather information about influenza vaccination policies and delivery practices. To calculate influenza vaccination rates for each facility, we obtained data on influenza vaccine orders from the Massachusetts Department of Public Health for each county in Massachusetts for influenza seasons 2013-2020. We calculated summary statistics for each reporting facility and each year, conducted a Kruskal–Wallis analysis to compare vaccination rates between years, and used a linear regression model to identify predictors of vaccination rates. Results Influenza vaccination rates in Massachusetts jails ranged from 1.9% to 11.8%. We found no significant differences in vaccination rates between years. Influenza vaccine ordering and delivery practices varied by jail, and respondents had high levels of confidence in influenza policies and vaccine delivery practices. Conclusions Influenza vaccination rates in Massachusetts jails are low, and delivery practices in jails vary. Lack of influenza vaccinations in jails is a gap in health care that needs to be prioritized, especially considering the current COVID-19 pandemic. Further investigations for effective and equitable vaccination in this population should involve people who are incarcerated and people who make influenza vaccine policies in jails.

Introduction/Objectives: Health-related social needs (HRSN) screening efforts have reported high rates of identified social needs. Little is known if efforts to conduct HRSN screening in resource-constrained federally-qualified health centers (FQHC) successfully captures a representative patient population. Methods: This cross-sectional study extracted EMR data from 2016 to 2020 for 4731 screened patients from 7 affiliated clinics of a FQHC. Unscreened patients were pulled as a random sample from the study period. A multivariable logistic regression was used to identify sociodemographic traits, chronic disease diagnoses and burden, and clinic visit type and frequency associated with being screened for HRSN. Results: Our FQHC screened 4731 unique patients or <1% of the total clinic population. Screened patients had a median of 3.3 (±2.5) unmet HRSN. Medicaid patients had higher odds of being screened (aOR = 1.38, CI 1.19-1.61) relative to Medicare patients. The odds of being screened for social needs increased with more provider visits per year: compared to fewer than 1 visit per year, patients with 1 to 3 provider visits (aOR = 2.06, CI 1.73-2.32), 4 to 6 provider visits (aOR = 3.34, CI 2.89-3.87), and more than 6 provider visits (aOR = 5.16, CI 4.35-6.12) all had higher odds of social needs screening. Patients with a higher comorbid disease burden (>2 conditions, aOR = 2.80, CI 2.07-3.79) had higher odds of screening. Conclusions: Our findings demonstrate an increased likelihood to screen patients who visit outpatient services more often and have a higher comorbid disease burden. To meet state-level Medicaid requirements, resource-constrained FQHCs that implement clinic wide HRSN screening may be well served to identify a priori strategies to ensure representative and equitable screening across the patient population.

HIV and hepatitis C virus (HCV) testing for all people in jail is recommended by the CDC. In the community, there are barriers to HIV and HCV testing for minoritized people. We examined the relationship between race and infectious diseases (HIV, HCV, syphilis) testing in one Massachusetts jail, Middlesex House of Corrections (MHOC). This is a retrospective analysis of people incarcerated at MHOC who opted-in to infectious diseases testing between 2016–2020. Variables of interest were race/ethnicity, self-identified history of psychiatric illness, and ever having experienced restrictive housing. Twenty-three percent (1,688/8,467) of people who were incarcerated requested testing at intake. Of those, only 38% received testing. Black non-Hispanic (25%) and Hispanic people (30%) were more likely to request testing than white people (19%). Hispanic people (16%, AOR 1.69(1.24–2.29) were more likely to receive a test result compared to their white non-Hispanic (8%, AOR 1.54(1.10–2.15)) counterparts. Black non-Hispanic and Hispanic people were more likely to opt-in to and complete infectious disease testing than white people. These findings could be related to racial disparities in access to care in the community. Additionally, just over one-third of people who requested testing received it, underscoring that there is room for improvement in ensuring testing is completed. We hope our collaborative efforts with jail professionals can encourage other cross-disciplinary investigations.

Background Injection drug use and needle sharing remains a public health concern due to the associated risk of HIV, HCV and skin and soft tissue infections. Studies have shown gendered differences in the risk environment of injection drug use, but data are currently limited to smaller urban cohorts. Methods To assess the relationship between gender and needle sharing, we analyzed publicly available data from the 2010–2019 National Survey on Drug Use and Health (NSDUH) datasets. Chi-square tests were conducted for descriptive analyses and multivariable logistic regression models were built adjusting for survey year, age, HIV status, and needle source. Results Among the entire sample, 19.8% reported receptive needle sharing, 18.8% reported distributive sharing of their last needle, and 37.0% reported reuse of their own needle during last injection. In comparison with men, women had 34% increased odds (OR 1.34, 95% CI 1.11–1.55) of receptive needle sharing and 67% increased odds (OR 1.67, 95% CI 1.41–1.98) of distributive needle sharing. Reuse of one's own needle did not differ by gender. Conclusions In this nationally representative sample, we found that women are more likely in comparison with men to share needles both through receptive and distributive means. Expansion of interventions, including syringe service programs, to increase access to sterile injection equipment is of great importance.

Background Studies on the impact of the novel SARS-CoV-2 virus (COVID) for healthcare workers (HCWs) rarely include the full spectrum of hospital workers, including less visible patient support roles. In the early days of the pandemic, COVID testing was preferentially available to HCWs. The objective of this study was to understand how individual experiences for all HCWs during the pandemic were associated with perceptions of access to, and receipt of COVID testing . Methods All hospital employees ( n  = 6736) in a single academic medical center in Boston, Massachusetts were invited to participate in a cross-sectional survey regarding perceived access to, and receipt of COVID testing during the first wave of the pandemic (March – August 2020). Responses were linked to human resources data. Log binomial univariate and multivariable models were used to estimate associations between individual and employment variables and COVID testing. Results A total of 2543 employees responded to the survey (38 %). The mean age was 40 years (± 14). Respondents were female (76 %), white (55 %), worked as nurses (27 %), administrators (22 %) and patient support roles (22 %); 56 % of respondents wanted COVID testing. Age (RR 0.91, CI 0.88–0.93), full time status (RR 0.85, CI 0.79–0.92), employment tenure (RR 0.96, CI 0.94–0.98), changes in quality of life (RR 0.94, CI 0.91–0.96), changes in job duties (RR 1.19, CI 1.03–1.37), and worry about enough paid sick leave (RR 1.21, CI 1.12–1.30) were associated with interest in testing. Administrators (RR 0.64, CI 0.58–0.72) and patient support staff (RR 0.85, CI 0.78–0.92) were less likely than nurses to want testing. Age (RR 1.04, CI 1.01–1.07), material hardships (RR 0.87, CI 0.79–0.96), and employer sponsored insurance (RR 1.10, CI 1.00-1.22) were associated with receiving a COVID test. Among all employees, only administrative/facilities staff were less likely to receive COVID testing (RR 0.69, CI 0.59–0.79). Conclusions This study adds to our understanding of how hospital employees view availability of COVID testing. Hazard pay or other supports for hospital workers may increase COVID testing rates. These findings may be applicable to perceived barriers towards vaccination receipt.

Background: Antimicrobial resistance (AMR) is a global public health crisis. A key strategy to combat AMR is to use targeted antibiotics, which is difficult in patients who report an allergy to penicillin. Increased risk for resistant infections, mortality, and healthcare costs are associated with penicillin allergies; however, up to 90% of those with a reported penicillin allergy do not have a true allergy. We investigated racial and ethnic differences related to penicillin allergy delabeling by analyzing rates of penicillin allergy reporting and referral for allergist consultation. Methods: Tufts Medical Center is a teaching medical center in Boston, Massachusetts. This study cohort contains all patients seen in 2019 by clinicians at Primary Care Boston, the main primary care practice at Tufts Medical Center. Demographic data, documented allergies, and referral history were collected from the electronic medical record. We performed univariate and multivariable analyses using logistic regression models. Covariates found to be statistically significant ( P < .05) in the univariate analyses were included in the multivariable model. Results: In total , 2,391 (11%) patients reported a penicillin allergy, but only 249 (10%) were referred to an allergist (Table 1). Black patients and Asian patients were less likely to report a penicillin allergy than White patients. We detected no differences related to Hispanic ethnicity. Black patients with penicillin allergy were more likely to be referred to an allergist. Conclusions: There were low rates of allergist referral for penicillin allergy delabeling in this cohort. We identified racial differences in both penicillin allergy reporting and allergist referral. Allergist consultation is an important opportunity to combat AMR and should be considered for all patients reporting a penicillin allergy. Future work should evaluate equitable access to allergy delabeling resources. Funding: None Disclosures: None

Healthcare workers (HCWs) experience barriers to severe acute respiratory coronavirus virus 2 (SARS-CoV-2) testing specific to their perceptions of access, and employment factors. A survey was sent to all employees at one Boston hospital to examine their perceived barriers to testing. HCWs who reported difficulty paying their bills were less likely to receive a SARS-CoV-2 test.

In preparation for institution-wide vaccination, the Middlesex Sheriff’s Office (MSO) developed and distributed two self-response surveys in December 2020 and January 2021 to assess COVID-19 vaccine willingness among people incarcerated in the jail and one for people who work at the jail. The goal of this study is to characterize vaccine willingness in these two populations of people at the Middlesex House of Correction and Jail with the ultimate goal of informing communication strategies to address concerns and increase acceptance of COVID-19 vaccination.

Abstract Hepatitis C virus (HCV) is curable, but incarcerated populations face barriers to treatment. In a cohort of incarcerated hospitalized patients in Boston, Massachusetts, HCV infection was associated with increased mortality. Access to HCV treatment in carceral settings is crucial to avoid unnecessary death and to support HCV elimination efforts.

Objective To quantify racial disparities in mortality and post-hospitalization outcomes among incarcerated individuals that were hospitalized during their incarceration period. Methods We designed a retrospective cohort study using administrative and hospital data collected from a preferred healthcare referral center for all Massachusetts jails and prisons between January 2011 and December 2018 with linkage to Massachusetts Vital Records and Statistics. We identified 4260 incarcerated individuals with complete data on race/ethnicity that were hospitalized during the study period. The primary study indicators were age, race, ethnicity, length of hospital stay, Elixhauser comorbidity score, incarceration facility type, and number of hospital admissions. The primary outcome was time to death. Results Of the incarcerated individuals that were hospitalized, 2606 identified as White, 1214 identified as Black, and 411 people who identified as some other race. The hazard of death significantly increased by 3% (OR: 1.03; 95% CI: 1.02–1.03) for each additional yearly increase in age. After adjusting for the interaction between race and age, Black race was significantly associated with 3.01 increased hazard (95% CI: 1.75–5.19) of death for individuals hospitalized while incarcerated compared to White individuals hospitalized while incarcerated. Hispanic ethnicity and being incarcerated in a prison facility was not associated with time to mortality, while increased mean Elixhauser score (HR: 1.07; 95% CI: 1.06–1.08) and ≥ 3 hospital admissions (HR: 2.47; 95% CI: 2.07–2.95) increased the hazard of death. Conclusions Our findings suggest disparities exist in the mortality outcomes among Black and White individuals who are hospitalized during incarceration, with an increased rate of death among Black individuals. Despite hypothesized equal access to healthcare within correctional facilities, our findings suggest that incarcerated and hospitalized Black individuals may experience worse disparities than their White counterparts, which has not been previously explored or reported in the literature. In addition to decarceration, advocacy, and political efforts, increased efforts to support research access to datasets of healthcare outcomes, including hospitalization and death, for incarcerated people should be encouraged. Further research is needed to identify and address the implicit and explicit sources of these racial health disparities across the spectrum of healthcare provision.
