Research Ethics in Training Curricula of Cameroon Health Training Institutions: A Cross-Sectional Study.

Introduction The quality of protection for research participants in Africa is still marked by the lack of trained actors in this area. The study was conducted to assess the availability of health research ethics in the curricula of health-related sciences training institutions in Cameroon. Methods The study involved a cross-sectional analysis to describe the training curricula on research ethics in health training institutions in Cameroon. Data were collected using a structured questionnaire that was administered face to face to the heads of institutions in late 2020. Results Twenty-one health training institutions were identified, and 18 (85.71%) participated. Health research ethics courses were present in the curricula of 16 (88.88%) of the institutions. Lectures were either a standalone module or part of a module in 14 (77.78%) institutions. The three first topics covered in the courses were the fundamental principles of ethics, the role of the ethics committee in the protection of research participants, and respect for research participants. A total of 14 (77.78%) institutions declared ethical clearance mandatory before the implementation of students' thesis protocols. Eight (50.00%) training institutions declared having at least one qualified lecturer to deliver training in research ethics evaluation. The organization of the training of lecturers in delivering lectures on research ethics was declared to be the main assistance needed. Conclusions The delivery of research ethics education in Cameroon's healthcare institutions is still limited by the fact that it does not cover all eligible populations, is not standardized, and does not yet promote the practice of requiring all student protocols to undergo preethical review prior to implementation. These points should be taken into account by the authorities in charge.

Training needs of health researchers in research ethics in Cameroon: a cross-sectional study.

BACKGROUND: Researchers are responsible for the protection of health research participants. The purpose of this study was to identify and prioritize the training needs of researchers involved in human health research in Cameroon. METHODS: It was a cross-sectional study conducted in all the Cameroon regions in the last quarter of 2020. It targeted researchers involved in human health research selected by systematic stratified sampling from health and training institutions, and health facilities. Data were collected using a face-to-face administered questionnaire deployed in Smartphones via the ODK-collect. The distribution of participants' exposure to research ethics training was described as well as their knowledge on the related regulatory texts. A score was used to rank the training needs identified by the participants. RESULTS: Of 168 reached participants, 134 (79.76%) participated in the study. A total of 103 (76.87%) researchers reported having received training in human health research ethics and 98 (73.13%) perceived need of training in research ethics. Of those involved in clinical, vaccine, and field trials, 63.64, 33.33, 52.53% have been exposed respectively to related training regarding participants' protection. Having received at least one training in research ethics significantly increase the proportion of researchers systematically submitting application for ethical evaluation prior to implementation (OR = 3.20 (1.31-7.78)). Training priorities identified by researchers include: guidelines and regulations on health research ethics and research participant's protection in Cameroon, procedures for evaluating research protocols, protection of research participants in clinical trials, and fundamental ethics principles. CONCLUSION: The coverage of researchers in training regarding research participant protection remains limited in a number of areas including those related to clinical trial participant protection and research participant protection in Cameroon. Improving this coverage and addressing perceived needs of researchers are expected to contribute in improving their ability in playing their role in research participant protection.

Tracking Demographic Movements and Immunization Status to Improve Children's Access to Immunization: Field-Based Randomized Controlled Trial.

BACKGROUND: Countries' Expanded Program on Immunization (EPI) contribute to the reduction of mortality and morbidity, but access to these vaccines remains limited in most low-income countries. OBJECTIVE: We aim to assess whether involving community volunteers (CVs) to track children's vaccination status and demographic movements and using recorded data to plan catch-up immunization sessions can improve children's vaccination timeliness, completeness, and coverage. METHODS: This was a field-based randomized controlled trial and communities of the Foumban health district in West Cameroon were allocated to intervention or control groups. In the intervention group, a CV per community was trained to visit households monthly for a year to assess and record in a register, details of EPI-targeted children, their demographic movements and immunization status. The scanned recorded pages were sent to the health center immunization team through WhatsApp and used to organize monthly community catch-up immunization sessions. In the control group, EPI vaccination sessions were routinely conducted. Surveys were conducted at 6 and 12 months from the beginning of the intervention in both study groups to assess and compare immunization timeliness, coverage, and completeness. RESULTS: Overall, 30 buildings per cluster were surveyed at midline and endline. Of the 633 and 729 visited households in the intervention group at midline and endline, 630 (99.5%) and 718 (98.4%), respectively, consented to participate. In the control group, 507 and 651 households were visited and 505 (99.6%) and 636 (97.7%), respectively, consented to participate. At 12 months intervention, the month one timeliness of bacille Calmette-Guerin (BCG) vaccine did not increase in the intervention group compared with the control group for the age groups 0-11 months (adjusted odds ratio [aOR] 1.1, 95% CI 0.7-1.8) and 0-59 months (aOR 1.1, 95% CI 0.9-1.4), and significantly increased for the first-year BCG vaccine administration for the age group 0-23 months (aOR 1.5, 95% CI 1.1-2.2). The coverage of diphtheria-pertussis-tetanus and hepatitis B+Hemophilus influenzae type B (DPT-Hi +Hb) dose 3 (aOR 2.0, 95% CI 1.5-2.7) and of DPT-Hi+Hb dose 1 (aOR 1.8, 95% CI 1.4-2.4) vaccines increased significantly in the intervention group compared with the control group in the age groups 12-59 months and 12-23 months, respectively. Specific (DPT-Hi+Hb dose 1 to DPT-Hi+Hb dose 3: aOR 1.9, 95% CI 1.4-2.6) and general (BCG to measles: aOR 1.5, 95% CI 1.1-2.1) vaccine completeness increased significantly in the intervention group compared with the control group. CONCLUSIONS: Findings support that involving CVs to track children's vaccination status and demographic movements and using recorded data to plan catch-up immunization sessions improve children's vaccination timeliness, completeness, and coverage. This strategy should be adopted to improve access to vaccination for EPI target populations and the consistency verified in other contexts.
