Risk factors for antiretroviral therapy (ART) discontinuation in a large multinational trial of early ART initiators.

OBJECTIVE: We aimed to investigate potential causes of higher risk of treatment interruptions within the multicountry Strategic Timing of AntiRetroviral Treatment (START) trial in 2015. METHODS: We defined baseline as the date of starting antiretroviral therapy (ART) and a treatment interruption as discontinuing ART for at least 2 weeks. Participants were stratified by randomization arm and followed from baseline to earliest end date of the initial phase of START, death, date of consent withdrawn or date of first treatment interruption. Cox regression was used to calculate hazard ratios and 95% confidence intervals for factors that may predict treatment interruptions in each arm. RESULTS: Of the 3438 participants who started ART, 2286 were in the immediate arm and 1152 in the deferred arm. 12.9% of people in the immediate arm and 10.5% of people in the deferred arm experienced at least one treatment interruption by 3 years after starting ART. In adjusted analyses, age [hazard ratio for 35-50 years: 0.75 (95% confidence interval: 0.59-0.97) and >50 years: 0.53 (0.33-0.80) vs. <35 years], education status [hazard ratio for postgraduate education vs. less than high-school education (0.23 (0.10-0.50))] and region [hazard ratio for United States vs. Europe/Israel (3.16 (2.09-4.77))] were significantly associated with treatment interruptions in the immediate arm. In the deferred arm, age and education status were significantly associated with treatment interruptions. CONCLUSION: Within START, we identified younger age and lower educational attainment as potential causes of ART interruption. There is a need to strengthen adherence advice and wider social support in younger people and those of lower education status.

Effect of education on blood pressure control in elderly persons: a randomized controlled trial.

BACKGROUND: It is not clear which educational strategy is most effective in helping patients to change their lifestyles. This study compared the efficacy of two different educational models on reducing blood pressure (BP). METHODS: This was a randomized controlled trial in ambulatory hypertensive patients >65 years of age. Workshops that aimed to develop self-management and patient empowerment (PEM) were compared to workshops that used a compliance-based model (CEM). The primary outcome was change in systolic BP at 3 months compared with basal values between groups (net reduction), measured by 24-h ambulatory BP monitoring. RESULTS: A total of 30 patients were educated with PEM and 30 others with CM. Both groups were statistically similar with regard to age (67 v 70 years), systolic BP (157 v 156 mm Hg) and diastolic BP (88 v 88 mm Hg), diabetes (23% v 31%), and basal natriuresis 116 v 121 mEq/day). There were more women in the PEM group (57% v 30%). The PEM group showed a significant reduction of 8 mm Hg (95% confidence interval [CI] 2 to 15), whereas the CM group showed a reduction of 3 mm Hg (95% CI -3 to 8), with a net reduction of 6 (95% CI -3 to 14). Mean net night-time systolic BP reduction was 12 mm Hg (95% CI 2 to 22). BP control was 70% in PEM group vs 45% in CM group (P = 0.045). The relative odds ratio for BP control for the PEM group after adjustment for age, sex, diabetes, basal blood pressure and changes in pharmacological treatment was 3.7 (95% CI 1.05 to 13.1). CONCLUSION: Based on these study results, the self-management education model was significantly more effective than the compliance-based model in BP control.
