RESUMO
The Vanderbilt-Nigeria Biostatistics Training Program (VN-BioStat) aims to establish a research and training platform for biostatisticians doing HIV-related research in Nigeria, including enhancing mid-level biostatistics capacity through annual workshops. This paper describes findings from the inaugural workshop in Kano, Nigeria. Participants were surveyed before and after the workshop to assess their self-perceived familiarity with and confidence in their abilities to use statistical software and apply specific statistical techniques, as well as to gather feedback regarding the conduct of the workshop and future topic areas. Of the 23 participants enrolled in the workshop, 22 (96%) completed both pre- and post-workshop assessments. In both pre-workshop and post-workshop surveys, participants ranked their confidence in statistical skills using Likert scales. Scores were transformed to a 0-100 scale, and averages computed. Participants also shared open-ended feedback about the workshop and suggested future topic areas. Before the training, the average participant reported having either a "beginner" (30% of participants) or "moderate" (43%) level of familiarity with R. Many participants (65%) rated themselves as having "moderate" or "expert" familiarity with SPSS. Pre-workshop averages for confidence ranged from 26 to 64, with lowest confidence in "expanding continuous covariates in regression models and interpret results" and highest confidence in "fitting and interpreting results from a linear regression model". Post-workshop averages for confidence were all above 70. The lowest post-workshop score (74) was for "fit and interpret results from a semiparametric linear transformation model". The greatest increase in confidence was observed in "expanding continuous covariates in regression models using splines and interpreting results" and the lowest increase was in "fitting and interpreting results from a linear regression model." Participants offered positive feedback on instructor effectiveness (4.9/5) and overall course quality (4.9/5). While the overall course was rated on a 0-100 scale as "moderately difficult" (mean ± SD: 40.5 ± 17.5), the participants felt the course was highly organized (87.7 ± 17.8), and the information was moderately easy to learn (81.9 ± 15.9). Suggestions for future workshops included providing supplementary resources for out-of-classroom learning and releasing codes in advance to enhance participants' preparation. Among suggestions for future workshop topics, 80% of respondents listed survival analysis. Lessons learned provide insight into how short-term training opportunities can be leveraged to build biostatistics capacity in similar settings.
RESUMO
This study examined the support for vaccine mandates and uptake among clinical and non-clinical staff at a tertiary hospital in northern Nigeria, focusing on variation of survey responses based on job position, socio-demographic characteristics, and perceived risk of infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Using an explanatory, sequential, mixed-methods design and deploying a pragmatic paradigm, 370 healthcare workers were administered structured questionnaires. This was followed by in-depth interviews with a sub-sample of respondents to further clarify the responses regarding support for the coronavirus disease 2019 (COVID-19) vaccine mandate. Findings demonstrated that less than one-half of respondents supported the COVID-19 mandate, and only one in three had received the recommended COVID-19 vaccine doses. Support for the vaccine mandate and vaccine uptake were predicted by profession, work experience, number of children, health status, and risk perception. Support for the vaccine mandate was ascribed to ethical and professional duty, whereas opposition was associated with respect for autonomy and human rights. This study documents the need to enhance support for vaccine mandates and uptake among healthcare workers through sustainable strategies, as Nigeria's healthcare workers are considered a source of trust and role models for the rest of society.
