Factors Associated with Treatment Success among Pulmonary Tuberculosis and HIV Co-infected Patients in Oyo State, South West-Nigeria

Background The co-existence of Tuberculosis (TB) and Human immunodeficiency Virus (HIV) is  known to increase morbidity and mortality in patients. The determinants of treatment success in TBHIV co-infection are not yet well studied. Such information can help optimise treatment and reduce morbidity and mortality.Objective To determine factors associated with antitubercular treatment success among TB I HIV coinfected patients.Methods A cross sectional study was carried out in fifty  three DOT clinics and treatment centres  using tuberculosis patient's records from January 2009 to December 2010 in Oyo state, Nigeria. The study population consisted of 7905 tuberculosis patients. Information on variables of interest were obtained with the use of data extraction forms. Chi-square and logistic regression were used to test the relationship between TB I HIV coinfection and socio-demographic variables, clinical characteristics and treatment success.Results Prevalence ofTB I HIV co-infection was found to be 14.2%. Patients with TB-HIV co-infection  were younger and more likely to be females. There were statistically significant association between treatment success and gender, marital status and patient point of care. After adjusting for other variables, it was found that patients receiving treatment in private facilities were independently less likely to be successfully treated compared with those receiving care in Public facilities. Female patients were also independently more likely to have better treatment outcome than male.Conclusion In addition to patients' point of care, gender of the patients can adversely impact on their treatment success. Efforts from the government to strengthening the private public mix, health education and media awareness on adherence to treatment to improve treatment success should be intensified in the country.Keywords: Tube rc ulosis; Human immunodeficiency virus, Directly observe therapy short-course;  Treatment success, Coinfection

An appraisal of the contextual drivers of successful antimicrobial stewardship implementation in Nigerian health care facilities

ABSTRACT: Objectives: Antimicrobial resistance (AMR) is a consequence of inappropriate actions, including irrational antimicrobial prescribing and use. Antimicrobial resistance remains an emergent and significant public health threat, particularly in low and middle-income countries (LMICs), including Nigeria. Optimizing antimicrobial (AM) use through functional hospital antimicrobial stewardship (AMS) programs is one of the strategies to control the spread of AMR. Literature is replete with evidence, but few studies examined the contextual factors limiting AMS functionality at the facility levels. This study explored the intrinsic contextual factors shaping AMS practice at the three-tiered levels of care. Methods: This was a qualitative case study with a purposeful sample size of 30 participants drawn from two primary, two secondary, and two tertiary health facilities in Nigeria. Data were coded and categorized for thematic analysis. Results: Emergent themes include lack of AMS programs, inadequate guidelines, lack of modern equipment and incorrect diagnosis, absence of continuous medical education, imbalance of power among professionals, and pervasive external influence of pharmaceutical marketing companies. These findings demonstrate that the AMS program is lacking or poorly implemented at the three-tiered level of care. Conclusion: We recommended that health facilities establish AMS programs in line with the World Health Organization's stepwise approach. These challenges, if addressed, will promote the successful performance of the AMS program, contributing to rational AM use at all levels of care. Since primary health centres constitute 85.4% of all health facilities, customizing the AMS core elements at this level will contribute to achieving the goals of universal health coverage
