One caretaker reported: "Antimalarial drugs are as well not available sometimes.
The caretaker reported the total number of missed doses for the past three days.
Adherence to antiretroviral therapy was assessed using caretaker report, medication return and nevirapine plasma concentration.
The Kappa statistic was used to assess agreement between adherence measures (caretaker report, medication return and nevirapine plasma concentration).
In our study, high adherence levels to ART by caretaker report (98%) and medication return (97%) were observed.
Nevirapine plasma concentration seems to give a better estimation of adherence to ART than caretaker report and medication return.
However, there was no significant difference in the level of adherence by caretaker report and medication return (p = 0. 0.).
These findings are similar those reported from Uganda where the level of adherence assessed using medication return and caretaker reporting was relatively high [ 20].
The aim of this study was to determine the level of adherence to antiretroviral therapy (ART), measured by caretaker report, medication return and nevirapine plasma concentration.
One male caretaker reported: "Before they could bring drugs, but after five or ten days you are told drugs are out of stock.
The HUAS-lite questionnaire consisted of 21 questions and was administered only for children whose caretaker reported an episode of diarrhea during the preceding 14 days.
