The problem to investigate
Community health staff may need to remind clients about pre-arranged appointments while juggling home visits and limited connectivity. A public messaging tool risks disclosing sensitive health information.
02 / THE BLUEPRINT
A possible solution
With programme authorisation, offer neutral opt-in appointment reminders that disclose no diagnosis and allow patients to choose or refuse contact. Staff determine scheduling and clinical priority.
03 / THE BLUEPRINT
Start without an app
A sealed paper appointment card and a consented phone call can be the safer baseline, especially for shared household phones.
04 / THE BLUEPRINT
Technology that could help
A staff-only list can store minimal contact preferences, reminder timing, opt-out and delivery failures with role-based access. Do not send clinical content through unprotected SMS.
05 / THE BLUEPRINT
Your first experiment
- Map one clinic's approved reminder process with authorised staff.
- Create fictional clients representing private and shared phone use.
- Ask patients what neutral message wording would be acceptable, with consent.
- Pilot under clinical governance and audit mistaken or unwanted messages.

People, resources and cost drivers
Needs a clinical programme owner, confidentiality policy, support budget, local-language materials and protected contact procedures. WHO primary-care digital handbook: https://www.who.int/publications/i/item/9789240093362
07 / THE BLUEPRINT
What to validate — and when to stop
Assess wrong-recipient rates, opt-out handling and whether missed reminders generate safe escalation. Stop if staff or family members access private information without permission.
08 / HYPOTHESIS TO TEST
Potential impact and how to measure it
Measure successful reminders, client satisfaction and completed appointments; do not claim improved health outcomes from reminders alone.
09 / THE BLUEPRINT
Risks and safeguards
Shared phones, coercive household relationships, stigma and misdirected messages can expose patients. Participation must be voluntary, privacy-protecting and easy to withdraw.
10 / THE BLUEPRINT
Who might pay or maintain it
A health facility may include reminder costs in its outreach budget, with explicit review of ongoing staffing and messaging charges.
