Bundling HIV and TB Care at a District-Level Center in Sierra Leone: A high-yield method for diagnosing co-infection with TB and antiretroviral treatment failure among people living with HIV

Abstract

Background: Protocols for HIV care are widely accepted by all international organizations and are proven to reduce mortality and complications from living with HIV. Unfortunately, executing best practice recommendations in Sierra Leone is difficult due to shortages in staff, training, and medications. Methods: From June 2016 to August 2016, we implemented both an HIV guideline-based clinical evaluation protocol and a patient-centered workflow for TB screening and CD4 testing in the HIV clinic at Koidu Government Hospital (KGH) in rural Sierra Leone. The primary outcome of interest was how often this service center resulted in a clinically significant change in the patients’ HIV regimen. Reasons for changing regimen included diagnosis of co-infection with tuberculosis (TB), diagnosis of clinical or presumed immunologic treatment failure of antiretroviral (ART) medications and, need for adherence to weight-based dosing in pediatric patients. Findings: A total of 188 patients with HIV were seen in the clinic; 49 (26%) of these patients had a clinically significant change in their HIV regimen. The most common reason for regimen change was TB co-infection diagnosis in 38 (20%) patients. The other reasons for HIV regimen changes included: eight children whose ART was adjusted to meet appropriate levels for weight-based guidelines, five patients diagnosed with presumed immunologic treatment failure (some also co-infected with tuberculosis), and two patients with a serious side effect to ART. Interpretation: A comprehensive, patient-centric HIV clinic can result in high rates of case detection for tuberculosis and recognition of immunological ART failure.
