Background: The World Health Organization (WHO) strongly recommends that brief tobacco interventions should be routinely offered in primary care. However, medical doctors do not consistently and effectively intervene during their encounters with cigarette smokers. There is a paucity of studies assessing the effect of training on the tobacco intervention competency of primary care doctors in Nigeria., Aim: To evaluate the effectiveness of online training in improving competency in brief tobacco interventions among primary care doctors in Delta State, Nigeria., Methods: A cluster-randomized controlled trial was conducted among eligible doctors working in government-owned facilities. The 22 eligible Local Government Areas (LGAs) served as clusters. The intervention group received a WHO six-hour online course on brief tobacco cessation intervention, delivered via Zoom. The control group received no intervention. A structured questionnaire was sent to participants via WhatsApp before and six months after the training. The primary outcome variables were scores for knowledge, attitude, self-efficacy, and practice. Differences in change of scores between intervention and control groups were assessed with t-test. To adjust for clustering, these inter-group differences were further analyzed using linear mixed-effects regression modeling with study condition modeled as a fixed effect, and LGA of practice entered as a random effect., Results: The intervention group had a significantly higher mean of change in scores for knowledge (effect size 0.344) and confidence (effect size 0.52)., Conclusion: The study shows that training, even online, positively affects clinician competency in brief tobacco intervention. This is important for primary care systems in developing countries. Mandatory in-service training and promotion of the WHO modules are recommended., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Moeteke et al.

Context: The undiagnosed and untreated tuberculosis (TB) cases underpin the experience of accelerating deaths. Everyone should be engaged in managing TB patients to revert the current trend., Aims: In this context, we assessed the outcome of an education intervention on the knowledge of TB and referral practice of presumptive TB cases to directly observed therapy strategy amongst patent medicine vendors (PMVs)., Settings and Design: The study was quasi-experimental, conducted amongst 647 PMVs in Delta State, Nigeria., Methods: A structured questionnaire was administered to obtain baseline data on knowledge of TB. An educational intervention on knowledge of TB was then given. A post-intervention assessment of TB knowledge was subsequently conducted using the same questionnaire. The exact number of referrals of presumptive TB cases by PMVs and the number that tested positive amongst the referred presumptive TB cases, 3 months before and after the training were obtained from the state TB database., Statistical Analysis Used: SPSS v. 26 was used for data analysis., Results: The pre-training knowledge average score was 15.45 ± 6.45, while the post-training average score was 19.44 ± 7.03 (P < 0.001). The pre-training average number of presumptive cases referred was 146 ± 124.7, and the post-training was 205.67 ± 255.4, P = 0.41. The pre-training average number of cases that turned out positive was 9.5 ± 6.3, and the post-training was 13.5 ± 11.3, P = 0.42., Conclusion: There was a significant improvement in PMVs' knowledge of TB post-intervention. However, while an increase in the number of cases referred and positives detected was observed, this was not significant. Periodic training and updates to PMVs in keeping with current trends and best practices in TB management are recommended.

Objective: The study aimed to examine health workers' perceptions of the coronavirus disease 2019 (COVID-19) vaccine in Nigeria and their willingness to receive the vaccine when it becomes available., Methods: This multi-center cross-sectional study used non-probability convenience sampling to enroll 1,470 hospital workers aged 18 and above from 4 specialized hospitals. A structured and validated self-administered questionnaire was used for data collection. Data entry and analysis were conducted using IBM SPSS ver. 22.0., Results: The mean age of respondents was 40±6 years. Only 53.5% of the health workers had positive perceptions of the COVID-19 vaccine, and only slightly more than half (55.5%) were willing to receive vaccination. Predictors of willingness to receive the COVID-19 vaccine included having a positive perception of the vaccine (adjusted odds ratio [AOR], 4.55; 95% confidence interval [CI], 3.50-5.69), perceiving a risk of contracting COVID-19 (AOR, 1.50; 95% CI, 1.25-3.98), having received tertiary education (AOR, 3.50; 95% CI, 1.40-6.86), and being a clinical health worker (AOR, 1.25; 95% CI, 1.01-1.68)., Conclusion: Perceptions of the COVID-19 vaccine and willingness to receive the vaccine were sub-optimal among this group. Educational interventions to improve health workers' perceptions and attitudes toward the COVID-19 vaccine are needed.
