Insights
Implementing the World Health Organization HEARTS model for integrated hypertension and diabetes care in Guatemala was feasible and acceptable. This pilot study offers valuable insights for scaling up cardiovascular disease management in primary care settings.
Area of Science:
- Global Health
- Primary Care Management
- Cardiovascular Disease Risk Factors
Background:
- The World Health Organization HEARTS Technical Package aims to enhance primary care for cardiovascular disease risk factors globally.
- This study piloted an integrated hypertension and diabetes management approach based on the HEARTS model in Guatemala.
Purpose of the Study:
- To report outcomes from a pilot implementation trial of integrated hypertension and diabetes management using the HEARTS model.
- To assess the feasibility and acceptability of the HEARTS-aligned strategies in Guatemalan primary care facilities.
Main Methods:
- A 6-month single-arm pilot implementation trial was conducted in 11 Guatemalan Ministry of Health primary care facilities.
- Five HEARTS-aligned strategies were evaluated to improve pharmacological treatment for hypertension and diabetes.
- Feasibility and acceptability were assessed via staff interviews, enrollment, and retention data.
Main Results:
- The pilot enrolled 964 patients with hypertension and/or diabetes.
- Feasibility and acceptability scores among staff exceeded benchmarks (median 5.0).
- While patient follow-up rates were lower than targeted (36%), hypertension treatment rates increased significantly.
Conclusions:
- Integrated hypertension and diabetes management based on the HEARTS model demonstrated general feasibility and acceptability in Guatemala's Ministry of Health.
- Findings can inform national scale-up efforts in Guatemala and guide similar HEARTS implementation projects internationally.
Background:
The World Health Organization HEARTS Technical Package is a widely implemented global initiative to improve the primary care management of cardiovascular disease risk factors. The study's objective is to report outcomes from a pilot implementation trial of integrated hypertension and diabetes management based on the HEARTS model in Guatemala.
Methods:
We conducted a single-arm pilot implementation trial over 6 months from October 2023 to May 2024 in 11 Guatemalan Ministry of Health primary care facilities in two districts. The pilot evaluated a package of five HEARTS-aligned implementation strategies to improve the pharmacological treatment of hypertension and diabetes. The primary outcomes were feasibility and acceptability, measured through 20 structured interviews with Ministry of Health employees and by examining enrollment and retention. Secondary outcomes included a suite of implementation and clinical outcomes, including treatment rate.
Results:
The study enrolled 964 patients, of whom 58.8% had hypertension only, 30.4% had diabetes only, and 10.8% had both conditions. Surveys on feasibility and acceptability among Ministry of Health staff had a median score of 5.0 (IQR: 5.0 to 5.0) and 5.0 (IQR range: 4.8 to 5.0), respectively, exceeding the prespecified benchmark of ≥3.5. Both districts achieved the prespecified benchmark of enrolling ≥25 hypertension patients and ≥25 diabetes patients. Only 36% of patients attended a follow-up visit within three months, lower than the prespecified benchmark of ≥75%. M treatment rates during the pilot increased by 22.3 (95% CI: 16.2 to 28.4; P<0.001) and 3.5 (95% CI: -1.6 to 8.7; P=0.17) patients per month for hypertension and diabetes, respectively.
Conclusions:
Implementation of an integrated hypertension and diabetes model based on HEARTS was generally feasible and acceptable in the Ministry of Health in Guatemala. Findings can refine national scale-up in Guatemala and inform HEARTS implementation projects in other settings.
