Sponsor's own description
This study tested whether mobile health (mHealth) tools can affect referral uptake among schoolchildren with vision problems.Visual impairment in children often goes untreated in low- and middle-income countries, even when detected during school screenings, because parents do not follow up on referral advice. In this randomized controlled trial, children aged 5-15 years from two government schools in Rawalpindi, Pakistan, were screened for vision problems using a smartphone-based application. Those identified with possible impairment were randomly assigned to one of two groups. The control group received the usual printed referral form, while the intervention group received the printed referral plus automated, multicomponent SMS reminders in the local language. These reminders included health promotion messages, a visual depiction of the child's vision, and practical instructions about how to reach the hospital. The main outcome was the proportion of referred children who attended the hospital within eight weeks. Secondary analysis examined whether referral uptake was linked with child and family characteristics such as age, sex, and parental education. This was a minimal-risk, school-based trial with 80 participants. The study was ethically approved by the Army Medical College Ethics Review Committee (NUMS). Findings are expected to provide new evidence on the usefulness of mobile phone-based reminders for improving eye health care among children in resource-limited settings.
