Risk factors influencing the epidemiology of drug resistant tuberculosis patients enrolled for treatment at the National Tuberculosis Referral Hospital, Swaziland

Abstract

The purpose of this study was to establish empirical evidence on risk factors influencing drug-resistant tuberculosis (DR-TB) in Swaziland. Globally factors have been identified and specific programmatic interventions were implemented to counter the emergence of DR-TB, but the case still remains with Swaziland. The research question was “What are the risk factors influencing the epidemiology of DR-TB patients enrolled for treatment at the National Tuberculosis Referral Hospital? The research objectives were to investigate factors that influence the emergence of DR-TB in Swaziland, to establish the relationship between DR-TB and HIV and to develop a poster that will exhibit the findings on the study on risk factors influencing the epidemiology of DR-TB. A mixed method was used. A qualitative study of participants using the in-depth one on one interview with a grand tour question “ What are the risk factors that resulted in you having DR-TB” and probing questions. The quantitative retrospective part was utilised to review medical records. Convenience sampling was utilised to recruit participants using an interview guide to collect data and random sampling for the quantitative aspect using a checklist to collect data. Risk factors influencing the development of DR-TB were identified to be previous treatment with anti-tuberculosis drugs, human immunodeficiency virus (HIV). The findings showed that the prevalence of HIV in DR-TB was 61% for HIV positive and 39% for negative and the quantitative data showed 77% HIV positive and 23% negative to HIV. Lack of education for patients and their families on precautionary measures to take when caring for a family member, and what to do in cases of developing side effects. This study concludes that both the need to ensure that bacteriologically confirmed patients are initiated to treatment, adhere to their treatment and complete treatment and due to the number of direct cases being infected with DR-TB ensuring that infection control strategies are put in place at work and at home settings
