Abstract

SETTING: Government-funded public health clinics in and around Gaborone, Botswana.

OBJECTIVE: To explore the challenges faced by care givers of children on treatment for tuberculosis (TB) to inform a more child-friendly approach to Botswana's National TB Programme (NTP) strategy.

DESIGN: Qualitative study using 28 in-depth interviews with care givers of children receiving anti-tuberculosis treatment.

RESULTS: Care givers identified five main challenges: long delays in their child's diagnosis, difficulty attending clinic for daily treatment, difficulty administering TB medications, stock-outs of TB medications leading to treatment interruptions, and inadequate TB education. Care givers prioritized these same five areas to improve the overall management of their child's TB.

CONCLUSION: Our findings suggest that despite accessing care through an NTP that adheres to World Health Organization guidelines, care givers for children on treatment in Botswana continue to encounter significant challenges. While each of these represents a potential threat to successful treatment, they can be addressed with relatively small systematic and programmatic adjustments. These results will inform the next version of the Botswana NTP guidelines towards a more child- and care giver-centered approach.

Abstract

<p><strong>PURPOSE: </strong>This study aimed to determine if disclosure of HIV status to adolescents impacted their medication adherence and how medication autonomy might explain observed effects.</p>

<p><strong>METHODS: </strong>Three hundred adolescents on HIV treatment using electronic medication monitors were followed for 24&nbsp;months while undergoing routine care. One hundred six of the adolescents were HIV disclosure-naïve and HIV status disclosure in this group was assessed quarterly. Analyses included data from the 75 adolescents who experienced disclosure during the study providing adherence and autonomy data both predisclosure and postdisclosure. Segmented generalized estimating equations were used to examine the trend of adherence and autonomy predisclosure and postdisclosure. Covariates assessed include age at disclosure, sex, and orphan status.</p>

<p><strong>RESULTS: </strong>Median age at study entry was 12.2&nbsp;years (interquartile range 11.6-12.9). Incident disclosure occurred in 75 (71%) of the adolescents at a median age of 13.1&nbsp;years (interquartile range 12.5-13.9). Adherence decreased by 11% (95% confidence interval [CI] 7-15, p &lt; .001) during the predisclosure period and by 22% (95% CI 9-36, p&nbsp;= .001) during the postdisclosure period. Adolescents' autonomy over their medication-taking increased over time, but disclosure did not impact the rate of increase in measured medication-taking autonomy. On a scale of 1-4 assessing autonomy (1&nbsp;= receiving directly observed therapy and 4&nbsp;= taking medicines mostly without supervision), autonomy increased by an average of .03 units/month (95% CI .02-.03, p &lt; .001) predisclosure and by .05 units/month (95% CI&nbsp;-.01 to .11, p&nbsp;= .42) postdisclosure.</p>

<p><strong>CONCLUSIONS: </strong>The findings suggest that, among perinatally HIV infected adolescents, HIV status disclosure may adversely impact treatment adherence. Postdisclosure support to HIV infected adolescents should be intensified.</p>

Pharmacy Refill Data are Poor Predictors of Virologic Treatment Outcomes in Adolescents with HIV in Botswana.

Abstract

<p>In adults living with HIV, pharmacy refill data are good predictors of virologic failure (VF). The utility of pharmacy refill data for predicting VF in adolescents has not been reported. We evaluated data from 291 adolescents on antiretroviral therapy. The main outcome measure was VF, defined as two consecutive HIV viral load measurements ≥ 400 copies/mL during 24-months of follow-up. Pharmacy refill non-adherence was defined as two consecutive refill adherence measurements &lt; 95% during the same period. Fifty-three (18%) adolescents experienced VF. One hundred twenty-eight (44%) adolescents had refill non-adherence. Refill non-adherence had poor discriminative ability for indicating VF (receiver operating characteristic AUC = 0.60). Sensitivity and specificity for predicting VF was poor (60% (95% CI 46-74%) and 60% (95% CI 53-66%), respectively). The lack of a viable surrogate for VF in adolescents highlights the urgent need for more access to virologic testing and novel methods of monitoring adolescent treatment adherence.</p>

Abstract

<p>Levels of adherence to HIV treatment are lower among adolescents compared with older and younger individuals receiving similar therapies. We purposely sampled the most and least adherent adolescents from a 300-adolescent longitudinal HIV treatment adherence study in Gaborone, Botswana. Multiple objective and subjective measures of adherence were available and study participants were selected based on sustained patterns of either excellent or poor adherence over a one-year period. Focus group discussions (FGD) and in-depth interviews (IDI) were conducted with the adolescents and a subset of their caregivers with the goal of revealing barriers and facilitators of adherence. Focus groups were segregated by adherence classification of the participants. Following coding of transcripts, matrices were developed based on participants' adherence classifications in order to clarify differences in themes generated by individuals with different adherence characteristics. 47 adolescents and 25 adults were included. The non-adherent adolescents were older than the adherent adolescents (median age 18 years (IQR 16-19) vs. 14 years (IQR 12-15 years)), with median time on treatment near 10 years in both groups. Interference with daily activities, concerns about stigma and discrimination, side effects, denial of HIV status, and food insecurity arose as challenges to adherence among both those who were consistently adherent and those who were poorly-adherent to their medications. Low outcome expectancy, treatment fatigue, mental health and substance use problems, and mismatches between desired and received social support were discussed only among poorly adherent adolescents and their caregivers. Challenges raised only among adolescents and caregivers in the non-adherent groups are hypothesis-generating, identifying areas that may have a greater contribution to poor outcomes than challenges faced by both adherent and non-adherent adolescents. The contribution of these factors to poor outcomes should be explored in future studies.</p>

Brief Report: Apparent Antiretroviral Over-adherence by Pill Count is Associated with HIV Treatment Failure in Adolescents.

Abstract

<p>Pill counts with calculated adherence percentages are used in many settings to monitor adherence, but can be undermined by patients discarding pills to hide non-adherence. Pill counts suggesting that &gt;100% of prescribed doses were taken can signal "pill dumping." We defined "over-adherence" (OA) among a cohort of 300 HIV-infected adolescents as having &gt;1/3 of pill counts with &gt;100% adherence during a year of follow-up. Apparent over-adherence was more common in those with virologic failure than those with suppressed viral loads (33% vs 13%, chi p=0.001). Pill count adherence repeatedly &gt;100% may identify HIV-infected adolescents at increased risk of treatment failure.</p>
