ABSTRACT

BACKGROUNDEngaging private health providers and community healthcare workers (CHWs) in the provision of TB care services can increase TB case notification and limit community transmission. We determined whether private pharmacy and community engagement could affect access to TB diagnostic and treatment services in Uganda.METHODSWe conducted a cross-sectional study on patients diagnosed with TB through three different pathways; by private pharmacies, CHWs, and public health facilities. We collected data on patient demographics, time between symptom recognition and TB treatment initiation, and the amount of money spent on TB care seeking.RESULTSWe collected data from 325 participants; 65.2% were male, with a mean age of 35 years (SD 11.50). The time in days between the onset of symptoms and initiation of treatment was significantly different: respectively 149 (IQR 65.5-295), 119 (IQR 51-200), and 106.5 (IQR 60-201) days for CHWs, pharmacies, and public facilities (P = 0.04). The longest time was between the first contact with a health provider and the TB diagnosis (51 days, IQR 19-104). Participants diagnosed at public health facilities incurred the highest costs.CONCLUSIONAlthough the use of CHWs and pharmacies did not shorten the TB treatment pathway, the costs incurred were lower than those in private health facilities..

ABSTRACT

OBJECTIVES: Scale-up of HIV services in sub-Saharan Africa has rapidly increased, necessitating evaluation of medication safety in these settings. Drug-drug interactions (DDIs) involving antiretrovirals (ARVs) in sub-Saharan Africa are poorly characterized. We evaluated the prevalence and type of ARV DDIs in Ugandan outpatients and identified the patients most at risk. METHODS: A total of 2000 consecutive patients receiving ARVs at the Infectious Diseases Institute, Kampala were studied. The most recent prescription for each patient was screened for clinically significant DDIs using www.hiv-druginteractions.org. Univariable and multivariable logistic regression were used to identify risk factors for DDIs. A screening tool was developed using significant risk factors and tested in a further 500 patients. RESULTS: Clinically significant DDIs were observed in 374 (18.7%) patients, with a total of 514 DDIs observed. Only 0.2% of DDIs involved a contraindicated combination. Comedications commonly associated with DDIs were antibiotics (4.8% of 2000 patients), anthelmintics (2.2%) and antifungals (3.5%). Patient age, gender, CD4 count and weight did not affect risk of DDIs. In multivariable analysis, the patient factors that independently increased risk of DDIs were two or more comedications (P < 0.0001), a PI-containing ARV regimen (P < 0.0001), use of an anti-infective (P < 0.0001) and WHO clinical stage 3-4 (P = 0.04). A scoring system based on having at least two of these risk factors identified between 75% and 90% of DDIs in a validation cohort. CONCLUSIONS: Significant ARV DDIs occur at similar rates in resource-limited settings and developed countries; however, the comedications frequently causing DDIs differ. Development of tools that are relevant to particular settings should be a priority to assist with prevention and management of DDIs.
