Antiretroviral stewardship in a tertiary academic hospital: The need for a clinical pharmacist.

ABSTRACT

Background: South Africa has the highest prevalence of people living with HIV globally. Although antiretroviral therapy provides solutions, evidence of antiretroviral resistance emerged, requiring the application of antiretroviral-stewardship programmes to curb medication-related problems. Aim: Identify and describe antiretroviral-stewardship pharmacist interventions in an active antiretroviral-stewardship programme. Setting: HIV-positive adults admitted to medical wards at a tertiary academic hospital in South Africa. Methods: A descriptive quantitative study was performed, utilising an antiretroviral-stewardship assessment tool to determine antiretroviral-related recommendations in the treatment of HIV-positive adults. The study employed purposive sampling. Treatment charts were evaluated to identify antiretroviral-stewardship recommendations. The number of recommendations highlighted the need for a clinical pharmacist in an active antiretroviral-stewardship programme. Descriptive data analysis with Pearson correlations was employed to display the data. Results: Medication-related problems were identified in 100% of study patients (n = 41), with an average of 2.46 interventions per patient. One-hundred-and-one medication-related problems were identified by using the antiretroviral-stewardship assessment tool. The identified problems included a lack of viral load testing (41, 100%), lack of CD4 count monitoring (15; 36.6%) and lack of prophylactic treatment against opportunistic infections (10; 24.4%). Medication-related problems included the presence of clinically significant drug-drug interactions and serious side effects, CD4 count decline despite being on antiretroviral therapy, unnecessary treatment interruptions including risk for IRIS, inappropriate antiretroviral therapy regimen, non-adherence and absence of treating tuberculosis as co-morbidity. Conclusion: Present study demonstrates the need of an active antiretroviral-stewardship programme's benefits. The possible role of the clinical pharmacist as active participant and leader in this programme is highlighted. Contribution Highlight the role of clinical pharmacists in antiretroviral stewardship.
