Knowledge, attitude and practice of staff of 4 hospitals in Yaoundé on the prevention of vertical transmission of hepatitis B

INTRODUCTION: Hepatitis B virus infection is a public health concern in Cameroon and worldwide. With hepatitis C virus, it is the first cause of liver cancer in Cameroon. The high prevalence of 11.9% in Cameroon is associated with the premature contamination at the perinatal period, due to vertical transmission, from mother-to-child. To put into practice the preventives measures, actors need a good knowledge on premature contamination of a baby. The general objective of this study was to evaluate the influence of level of knowledge on the attitudes and the professional practices concerning prevention of mother-to-child transmission of hepatitis B (PMTCT/HBV) in Yaoundéhospitals and environs. METHODS: We carried out a cross sectional multicentric, KAP study from 10(th) March to 15(th) December 2015 in the obstetrics services of 4 hospitals in Yaoundéand environs. For each health care provider who gave his consent, we used a pretested questionnaire to collect socio-demographics and professional data as well as their knowledges, attitudes and practices on PMTCT/HBV. After given a grade to each item, we proceeded to a quantitative analysis of data using SPSS software and Epi info 7(th) version. RESULTS: 105 health care provider took part in the study, made up of 82 women (79%) and 22 men (21%). The ages were between 23 and 60 years, with a mean age of 40.9 ± 9.2 years. Only 21% of the participants had good knowledges on HBV/PMCT. This knowledge had a significant link with the profession, the professional experience and the duration in the same service. All the nurseaids had inadequate knowledges as well as the elders in the profession. Most of the participants (64.4%) had favorableattitude on PMTCT/HBV and that was significantly associated to good knowledges. (OR:5.34; CI 95% [1.47-19.47], p = 0.006). The practices on PMTCT/HBV were inappropriate in 57.1% of the participants. There were no significant relation between good knowledge and the practices (OR: 1.818, CI 95% [0.705-4.68]; p = 0.213) as well as between good attitudes and practices on PMTCT/HBV (OR: 0.932; CI 95% [0.423-2.058]; p = 0.862). CONCLUSION: The healthcare provider in hospitals in Yaoundé and its environs are old. Their knowledge on PMTCT/HBV is inadequate and their practices inappropriate. Good knowledge doesn't always lead to good practices of PMTCT/HBV. There exist some obstacles or intermediate variables between good knowledge, good attitudes and appropriate practices of PMTCT/HBV.
