Insights
Accurate medication adherence is vital for pediatric HIV treatment. A new interview effectively identifies adherence challenges by assessing caregiver knowledge of dosing, improving patient outcomes.
Area of Science:
- Pediatric infectious diseases
- HIV/AIDS management
- Adherence research
Background:
- Medication adherence is crucial for effective pediatric HIV treatment.
- Current adherence assessment methods can be complex or infeasible.
- There is a need for improved, practical adherence measurement tools.
Purpose of the Study:
- To evaluate a novel multidimensional adherence interview for assessing pediatric HIV medication adherence.
- To determine if the interview can accurately detect potential treatment nonadherence.
- To identify factors associated with viral load (VL) in children with HIV.
Main Methods:
- Caregiver data (N = 126) from perinatally HIV-infected children were analyzed.
- A revised adherence interview guide was used to collect data.
- Bivariate and multivariate analyses examined associations between adherence indicators and VL.
Main Results:
- Viral load (VL) was not significantly associated with 3-day recall of missed doses.
- Caregiver knowledge of prescribed dosing frequencies was the only factor uniquely associated with VL in multivariate analyses.
- The interview successfully identified family struggles with medication adherence.
Conclusions:
- The modified adherence interview effectively identifies adherence challenges in pediatric HIV care.
- Caregiver knowledge of dosing is a key factor linked to treatment success.
- This tool can assist clinicians in addressing adherence barriers and improving patient outcomes.
Abstract:
Medication adherence is critical for children's HIV treatment success, but obtaining accurate assessments is challenging when complex measurement technologies are not feasible. Our goal was to evaluate a multidimensional adherence interview designed to improve on existing adherence measures. Data from caregivers (N = 126) of perinatally infected children were analyzed to determine the ability of the revised interview guide to detect potential treatment nonadherence. Questions related to viral load (VL) on a bivariate level included proportion of doses taken in the previous 3 days and 6 months, caregivers' knowledge of prescribed dosing frequencies, and caregivers' reports of problems associated with medication administration. VL was not associated with 3-day recall of missed doses. In multivariate analyses, only caregiver knowledge of prescribed dosing frequencies was uniquely associated with VL. Our modified interview appears to successfully identify family struggles with adherence and to have the capacity to help clinicians address medication adherence challenges.
