In 30 seconds
This randomized controlled trial evaluated a digitally augmented health promotion intervention for emergency department patients in Hong Kong. Among 572 adults with health-risk behaviors, 30.1% in the intervention group achieved self-reported abstinence at 6 months compared to 19.9% in the control group (RR = 1.51; P = 0.006).
Key findings
- 30.1% of intervention participants achieved abstinence at 6 months versus 19.9% in controls (RR = 1.51; P = 0.006).
- The intervention increased the likelihood of fewer risky behaviors at 6 months (RR = 1.54; P = 0.01).
- Physical inactivity improved significantly at 6 months (31.7% vs 16.2%; P < 0.001).
- Effects diminished after cessation of booster messaging.
Why it matters
This study highlights the potential of using digital tools to promote behavior change in patients discharged from emergency departments, addressing modifiable risk factors for noncommunicable diseases.
What to keep in mind
Limitations include reliance on self-reported outcomes, a single-center design, and loss to follow-up, which may affect generalizability.
