Clinical Scorecard: Mobile Application Intervention for Preventing Unintentional Injuries in Preschoolers in Rural China: A Cluster Randomized Controlled Study

At a Glance

Key Highlights

• 12-month cluster randomized controlled trial with 3836 preschoolers and caregivers in rural China
• App-based intervention significantly reduced unintentional injury incidence (adjusted RR = 0.93)
• Intervention improved caregivers' safety attitudes, supervision behaviors, and home environment safety

Guideline-Based Recommendations

Diagnosis

• Assess unintentional injury incidence and risk factors among preschoolers in rural settings

Management

• Implement theory-driven, culturally-adapted mHealth educational interventions targeting caregivers
• Use mobile applications to deliver accessible, low-cost injury prevention education in resource-limited areas

Monitoring & Follow-up

• Track injury incidence rates and caregiver safety-related attitudes and behaviors over time
• Monitor app engagement metrics such as login frequency and usage duration

Risks

• High unintentional injury risk among rural preschoolers, especially from falls and blunt force injuries
• Challenges in traditional education delivery due to resource limitations and low professional availability

Patient & Prescribing Data

Rural Chinese preschoolers and their caregivers

App-based education is feasible with high retention (87%) and engagement, effectively reducing injury incidence and improving safety practices

Clinical Best Practices

• Leverage mobile health technology to overcome geographic and resource barriers in rural injury prevention
• Design interventions based on behavioral theory and cultural adaptation to enhance caregiver engagement
• Focus on improving caregiver supervision and home safety environment to reduce injury risk
