Outcome of training of maternal and child health workers in Ifo Local Government Area, Ogun State, Nigeria, on common childhood blinding diseases: a pre-test, post-test, one-group quasi-experimental study

BACKGROUND: Maternal and child health workers (MCHWs) are often the first point of contact with pregnant women, children, and caregivers. Therefore, they can play a significant role in early detection of causes of childhood blindness, facilitate prompt referral to specialized centers and provide health education to caregivers for preventive eye care. METHODS: This is a pre-test, post-test, single group, quasi-experimental study to evaluate the outcome of training MCHWs on common blinding childhood diseases. All MCHWs in Ifo Local Government Area were selected to participate in the study. Pre-training, qualitative data was obtained from two focus group discussions while quantitative data was obtained using a self-administered questionnaire. Three months post-training, quantitative data was obtained using the same self-administered questionnaire as was used pre-training. Total and percentage scores on the pre- and post-tests were calculated for each participant. A score of ≥70% was regarded as sufficient while < 70% score was regarded as insufficient. McNemar’s test was used to determine differences in proportions between pre- and post-training quantitative measurements. RESULTS: Of the 65 MCHWs in the Local Government Area, 61 participated in the study giving a response rate of 93.8%. The age range of study participants was from 28 to 57 years with a mean age of 41 ± 8.3 years. The male: female ratio was 1:7.7. During the focus group discussions, measles was the most commonly mentioned cause of childhood blindness however, participants showed more knowledge of the signs and symptoms of new-born conjunctivitis. Based on a sufficient knowledge score of ≥70%, only one participant (1.6%) demonstrated sufficient knowledge on quantitative survey pre-training. Post-training, there was a statistically significant increase (20, 32.8%) in the proportion of participants with sufficient knowledge (McNemar’s test p = .000). CONCLUSIONS: This study demonstrated that the training of MCHWs on common childhood blinding diseases (such as congenital cataract and congenital glaucoma) had the potential to improve knowledge regarding prevention, prompt recognition and early referral of common treatable potentially blinding diseases.
