Area of Science:

  • Digital Health
  • Health Informatics
  • Global Health

Background:

  • Significant global shortfall in specialized healthcare professionals, particularly in low-middle-income countries.
  • Implementation of task-shifted interventions to address healthcare worker shortages.
  • Lack of software and system guidelines for task-shifted interventions by the World Health Organization (WHO).

Purpose of the Study:

  • To formulate software requirements for computer systems supporting task-shifted interventions.
  • To address the challenge of mental health treatment delivery through task-shifting.
  • To illustrate software requirements using a mobile system for a depression intervention in Brazil.

Main Methods:

  • Identified 9 software requirements based on WHO guidance for task-shifted interventions.
  • Developed a system with mobile Android and Web interfaces for a psychosocial depression intervention.
  • Conducted a pilot study with 33 patients and 11 health workers, followed by a usability study with 8 health workers.

Main Results:

  • System usability rated between OK and Good based on qualitative and quantitative feedback.
  • Some users required technical assistance, indicating issues with correct use and skill acquisition.
  • Perceived usefulness and ease of use questionnaires highlighted areas for improvement.

Conclusions:

  • High-level software requirements effectively supported the intervention delivery.
  • Improvements needed for system usability in task-shifted interventions.
  • Key areas for enhancement include training access, supervisor data access, and robust patient data management.
