Abstract

OBJECTIVE:

To determine the adherence rate and its determinants among people living with HIV/AIDS on highly active antiretroviral therapy (HAART) in selected governmental hospitals from central and south Ethiopia.

METHODOLOGY:

A cross-sectional study involving both qualitative and quantitative methods was conducted between August and October 2007 in Yirgalem, Hawassa, and Shashemene Hospitals. Quantitative data collection techniques include patient self-report and unannounced pill count and the qualitative methods employed were focus group discussions (FGDs), semi-structured interviews, and observations of health facilities.

RESULTS:

Whereas females accounted for 56.4% (238), male participants were 43.6% (184) of the total participants. Adherence rate was 93.1% using 15-days self-report, but the rate came down to 88.1% when calculated using the unannounced pill count method (n = 90). Multivariate analysis revealed that being unmarried (OR = 0.119, CI = 0.016-0.901, p = 0.039), unemployment (OR = 0.011, CI = 0.000-0.288, p = 0.007); failure to disclose HIV status (OR = 0.433, CI = 0.198-0.949, p = 0.037); lack of support from family (OR = 0.393, CI = 0.163-0.947, p = 0.037); or others (OR = 0.332, CI = 0.144-0.845, p = 0.043); alcohol drinking (OR = 0.210, CI = 0.071-0.617, p = 0.003); treatment regimen, stavudine(40)-lamuvidine-nevirapine (OR = 0.174, CI = 0.033-0.923, p = 0.040), azathymidine-lamuvidine-nevirapine (OR = 0.172, CI = 0.034-0.867, p = 0.033) and dosing three times daily (OR = 0.073, CI = 0.018-0.290, p = 0.000) regimens were found to be associated with non-adherence. Moreover, time since diagnosis was associated with adherence, as those tested HIV-positive >or= 6 months prior to date of interview (OR = 4.064, CI = 1.23-19.316, p = 0.047) had better adherence rate.

CONCLUSION:

The adherence rate obtained in this study was higher than the rates seen in developed countries despite the fact that many of the participants live in very poor conditions.
