RESUMEN
Hypertension is a leading contributor to mortality in low-middle income countries including Haiti, yet only 13% achieve blood pressure (BP) control. We evaluated the effectiveness of a community-based hypertension management program delivered by community health workers (CHWs) and physicians among 100 adults with uncontrolled hypertension from the Haiti Cardiovascular Disease Cohort. The 12-month intervention included: community follow-up visits with CHWs (1 month if BP uncontrolled ≥140/90, 3 months otherwise) for BP measurement, lifestyle counseling, medication delivery, and dose adjustments. Primary outcome was mean change in systolic BP from enrollment to 12 months. Secondary outcomes were mean change in diastolic BP, BP control, acceptability, feasibility, and adverse events. We compared outcomes to 100 age, sex, and baseline BP matched controls with standard of care: clinic follow-up visits with physicians every 3 months. We also conducted qualitative interviews with participants and providers. Among 200 adults, median age was 59 years, 59% were female. Baseline mean BP was 154/89 mmHg intervention versus 153/88 mmHg control. At 12 months, the difference in SBP change between groups was -12.8 mmHg (95%CI -6.9, -18.7) and for DBP -7.1 mmHg (95%CI -3.3, -11.0). BP control increased from 0% to 58.1% in intervention, and 28.4% in control group. Four participants reported mild adverse events. In mixed methods analysis, we found community-based delivery addressed multiple participant barriers to care, and task-shifting with strong teamwork enhanced medication adherence. Community-based hypertension management using task-shifting with CHWs and community-based care was acceptable, and effective in reducing SBP, DBP, and increasing BP control.
RESUMEN
Infection with Corynebacterium diphtheriae persists in Haiti. Twenty-six children with clinically severe respiratory diphtheria presented to a hospital in northern Haiti during a 3-year period beginning in early 2015. The mortality rate was 50%. Partial or absent vaccinations as well as delayed and limited care contributed to mortality. This cohort offer insights into the multiple challenges involved in preventing and caring for children with diphtheria in resource-limited settings.
