Community health workers experiences with a digital clinical decision support system for longitudinal hypertension and diabetes care in rural Lesotho: a mixed-methods study

In rural Lesotho, 103 community health workers reported high usability of the ComBaCaL Community Health Toolkit app, with a mean System Usability Scale score of 75.6 (SD 13.0).

• Why it matters: CHWs delivering chronic hypertension and diabetes care need support for complex, longitudinal workflows in resource-constrained settings, where guidance and coordination can be difficult to sustain.
• What they did: Within the ComBaCaL project, all 103 CHWs completed a 38-item questionnaire and 22 joined interviews or focus groups to assess usability, satisfaction, benefits, and challenges.
• The result: Usability was high (98% satisfied or very satisfied; 98% rated general functions and diagnosis/treatment tasks easy or very easy), with benefits like task reminders (92%) and structured guidance (87%), while challenges included lengthy questionnaires and limited internet connectivity.
