Preliminary study of Hepatitis B surface antigen on mental health care workers at federal neuropsychiatric hospital Barnawa, Kaduna Nigeria

Background: This study was designed to determine retrospectively, HBsAg status, marker of HBV infection, among Mental Health Care Workers (MHCWs) at Federal Neuropsychiatric Hospital (FNPH), Barnawa Kaduna, North West, Nigeria. Two hundred and fifty one, apparently healthy HBV vaccine naïve, MHCWs, who voluntarily participate prior to HBV-vaccination. Materials and Methods: The screening was carried out using atlas latex haemagglutination test kit, between the months of December, 2000 through March, 2001. The MHCWs were categorized into senior and junior staff. Their ages, years of service, occupation, and department were obtained from year 2000 staff nominal roll. Prior to the study ethical approval was obtained from the hospital ethical committee. Two hundred and fifty one, participant were tested for HBsAg in a pre-HBV-vaccination exercise. Results: The number and percentages of participants by gender were 127 (50.6%) males and 124 (49.4%) females, respectively. The age range was 19-60 years with a mean age of 37 ± 2 years. The Number and percentages of junior and senior staff were 163 (65.0%) and 88 (35.0%), respectively. The incidence of HBsAg was 72 (28.7%). Incidence rates was highest among the males 41 (32.3%) compared to females 31(25.0%) and51-60yrs (50.0%), the incidence among Junior Staff was 52 (31.9%), while in Senior staff was 20 (22.7%) respectively. MHCWs who served between 26-30 years were 2 (66.7%) and those within 21-25 years were 6 (26.1%). Medical Record Staff were 3 (60.0%) and staff from other departments were Pharmacy 3 (50.0%), Artisans 7 (46.7%), Security 15(42.9%), Occupational Therapy Staff 2 (40.0%), Account Staff 6 (30.0%), Social Welfare 1 (25.0%), Hospital Maids 14 (23.7%), Administration Staff 11 (23.4%), Nurses 8 (17.0%), Medical Laboratory Staff 0 (0.0%), respectively. Statistical analysis obtained using Chisquare (x2) test showed no statistically significant association (p >0.05) between incidence of HBV-infection and years of service, Sex, Age, Cadre and Occupation. Conclusions: Due to a high prevalence of HbsAg, a marker of HBV infection, among MHCWs, Pre-vaccination screening should be instituted in Nigeria’s mental health facilities for early detection of HBV-infection and selective treatment.
