Deepening Our Understanding of COVID-19 Vaccine Decision-Making amongst Healthcare Workers in Southwest Virginia, USA Using Exploratory and Confirmatory Factor Analysis.

Vaccine hesitancy amongst healthcare workers (HCWs) has been a major challenge throughout the COVID-19 pandemic. While many studies have identified HCW characteristics and specific attitudes associated with COVID-19 vaccine hesitancy, researchers are still working towards developing a holistic understanding of the psychological constructs that influence COVID-19 vaccine decision-making in this population. Between 15 March and 29 March 2021, we distributed an online survey assessing individual characteristics and vaccine-related perceptions to employees of a not-for-profit healthcare system in Southwest Virginia (N = 2459). We then performed exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) to describe patterns of vaccine-related thought amongst HCWs and identify latent psychometric constructs involved in vaccine decision-making. The goodness of model fit was assessed using the Tucker-Lewis Index (TLI), the Comparative Fit Index (CFI), and the Root Mean Square Error of Approximation (RMSEA). Internal consistency and reliability of each factor were assessed using Cronbach's alpha. EFA identified four latent psychometric constructs: Lack of trust in the COVID-19 vaccine; Anti-science sentiment; Adverse side-effects; and Situational risk assessment. The goodness of EFA model fit was adequate (TLI > 0.90, RMSEA ≤ 0.08) with acceptable internal consistency and reliability for three of four factors (Cronbach's alpha > 0.70). The CFA model also had adequate goodness of fit (CFI > 0.90, RMSEA ≤ 0.08). We believe the psychometric constructs identified in this study can provide a useful framework for interventions to improve vaccine uptake amongst this critical population.

When Should Healthcare Workers With Coronavirus Disease 2019 (COVID-19) Return to Work? An Analysis of Follow-up Antigen Test Results After a Positive COVID Test.

A high percentage of healthcare workers (HCWs) who had met the Centers for Disease Control and Prevention criteria for returning to work 5 days after symptom onset remained positive for their return-to-work COVID-19 antigen test, suggesting continued infectiousness. Boosted HCWs were more likely to be antigen positive on their return-to-work test compared to unvaccinated HCWs, which merits further research.

Examining drivers of coronavirus disease 2019 (COVID-19) vaccine hesitancy among healthcare workers.

OBJECTIVE: To assess characteristics and perceptions associated with vaccine hesitancy among healthcare workers to increase coronavirus disease 2019 (COVID-19) vaccine uptake in this population. DESIGN: Cross-sectional quantitative survey. SETTING: A not-for-profit healthcare system in southwestern Virginia. PARTICIPANTS: A convenience sample of 2,720 employees of a not-for-profit healthcare system. METHODS: Between March 15 and 29, 2021, we conducted an Internet-based survey. Our questionnaire assessed sociodemographic and work-related characteristics, vaccine experience and intentions, agreement with vaccine-related perceptions, the most important reasons for getting or not getting vaccinated, and trusted sources of information about COVID-19. We used χ2 analyses to assess the relationship between vaccine hesitancy and both HCW characteristics and vaccine-related perceptions. RESULTS: Overall, 18% of respondents were classified as vaccine hesitant. Characteristics significantly associated with hesitancy included Black race, younger age, not having a high-risk household member, and prior personal experience with COVID-19 illness. Vaccine hesitancy was also significantly associated with many vaccine-related perceptions, including concerns about short-term and long-term side effects and a belief that the vaccines are not effective. Among vaccine-acceptant participants, wanting to protect others and wanting to help end the pandemic were the most common reasons for getting vaccinated. Personal physicians were cited most frequently as trusted sources of information about COVID-19 among both vaccine-hesitant and vaccine-acceptant respondents. CONCLUSIONS: Educational interventions to decrease vaccine hesitancy among healthcare workers should focus on alleviating safety concerns, emphasizing vaccine efficacy, and appealing to a sense of duty. Such interventions should target younger adult audiences. Personal physicians may also be an effective avenue for reducing hesitancy among their patients through patient-centered discussions.

Using financial diaries to understand the economic lives of HIV-positive pregnant women and new mothers in PMTCT in Zomba, Malawi.

BACKGROUND: Economic strengthening (ES) interventions can address economic barriers to retention and adherence (R&A) to antiretroviral therapy in prevention of mother-to-child transmission (PMTCT) services. To inform tailoring of ES activities for PMTCT, we used financial diaries to understand the economic lives of women in PMTCT and examine associations between participants' finances and their R&A. METHODS: We collected financial data from a stratified sample (n = 241) of HIV-positive pregnant women and new mothers enrolled in PMTCT from three clinics in Zomba, Malawi. For 30 weeks, participants met with staff to record cash and in-kind inflows and outflows. We used clinical records to calculate a measure of R&A for each participant. We summarized diary data using R and used cox proportional hazard models to examine the relationship between R&A and participant characteristics and behavior. RESULTS: There were 68,097 cash transactions over 30 weeks, with 10% characterized as inflows. The median value of cash inflows was US$3.54 compared with US$0.42 for cash outflows. Fewer than 7% of total transactions were considered related to PMTCT, with the majority classified as food or drink. Participants in the rural site had the lowest hazard of non-adherence. Decreased hazard of non-adherence was also linked to having dependents and years on ART. There were significant differences in cash inflows and outflows between those who were always adherent and those who were not. CONCLUSIONS: Financial inflows were large and erratic, whereas outflows were small but consistent. PMTCT expenses comprised a small proportion of overall expenses and focused on proper nutrition. The influence of inflows and outflows on adherence was significant but small; however, always adherent participants demonstrated smoother inflows and outflows, indicating an association between greater adherence and economic stability. Participants would benefit from interventions that bolster and stabilize their economic lives, including income generating activities in the agricultural industry and inclusion in village banks.

Economic strengthening for HIV testing and linkage to care: a review of the evidence.

Delayed HIV diagnosis and enrollment in HIV care can lead to negative health outcomes for individuals and pose major barriers to achieving the UNAIDS 90-90-90 treatment targets. Household economic strengthening (HES) initiatives are increasingly used to alleviate the direct and indirect costs of HIV testing and linkage to care for those who are diagnosed. The evidence linking HES with a range of HIV outcomes is growing, and this evidence review aimed to comprehensively synthesize the research linking 15 types of HES interventions with a range of HIV prevention and treatment outcomes. The review was conducted between November 2015 and October 2016 and consisted of an academic database search, citation tracking of relevant articles, examination of secondary references, expert consultation, and a gray literature search. Given the volume of evidence, the results are presented and discussed in three papers. This is the second paper in the series and focuses on the 20 studies on HIV testing, diagnosis, and enrollment in care. The results indicate that financial incentives are consistently and independently linked with higher testing uptake and yield among adults. Limited evidence indicates they may also be beneficial for enrollment in care. Evidence for other HES interventions is too sparse to identify clear trends.
