HIV and hepatitis B virus co-infection in Mozambique: Policy review and health professionals’ knowledge and practices

Abstract

Background Human Immunodeficiency Virus (HIV) and Hepatitis B Virus (HBV) co-infection is a public health problem affecting 2.7 million worldwide. In Mozambique, the prevalence of this co-infection is 9.1%, calling for specific policies on prevention, diagnosis and adequate management in health facilities caring for HIV patients. This study aimed to review the existing policies and to assess the knowledge and practices of health professionals about HIV/HBV co-infection. Methods A document and literature review to describe the existing policies and guidelines on HIV/HBV co-infection in Mozambique was performed. Key informants were contacted to clarify or add information. Health Professionals who care for HIV-positive patients in four health centers in Maputo City, the capital of Mozambique, responded to a questionnaire on knowledge and practices about this co-infection. Qualitative analysis was done to identify main themes using content analysis. Descriptive statistics of socio-demographic, knowledge and practice variables was presented using the SPSS Program version 20 and bivariate analysis was applied to describe the association between variables. Results Twenty-one policy documents were found, and five key informants were interviewed. Fifty-two participants answered the questionnaire. Only one policy document explicitly referred to HIV/HBV co-infection treatment. Most Health Professionals (96%) were aware of HIV/HBV co-infection. Although the only existing policy is on the treatment, few (33%) referenced antiretroviral formulations containing Tenofovir and Lamivudine. Only 29% of Health Professionals reported screening HIV patients for HBV and 21% practiced HIV/HBV co-infection counselling. No statistically significant differences were found when relating the socio-demographic variables with knowledge and practices. Conclusion Policy documents relating to prevention, diagnosis and clinical management of HIV/HBV co-infection were rare or absent. Health Professionals had little knowledge about HIV/HBV co-infection. Defining adequate policies and training of Health Professionals may help increase awareness, increase counselling of patients for disease prevention, diagnosis and proper management of HIV/HBV co-infected patients.
