TB pillbox reminders beat SMS for doses
In a China cluster RCT, medication-monitor reminders cut poor TB adherence 40–50%, while text messages mainly reduced loss to follow-up.

Effectiveness of Electronic Reminders to Improve Medication Adherence in Tuberculosis Patients: A Cluster-Randomised Trial
What they did
Across 36 clusters, investigators randomized pulmonary TB patients to control, SMS, medication monitor, or combined reminders and tracked missed doses and follow-up.
What they found
Medication monitors reduced poor adherence by 40–50% vs standard care; SMS alone did not improve adherence but cut loss to follow-up by 58%; 4,173 patients were analyzed.
The limits
What it doesn't show
Whether better adherence translates to microbiologic cure in this report, or how well monitors work outside China’s NTP.
