How a brief phone call can transform emergency room recovery
In short: In a major Hong Kong hospital, researchers tested a simple idea: could a quick telephone intervention combined with mobile messaging help patients stay healthy after leaving the emergency department? The results suggest that digital support can significantly boost the chances of breaking harmful habits.
A randomized controlled trial conducted in a major public hospital in Hong Kong investigated whether a digitally augmented health promotion strategy could help patients abstain from health-risk behaviors. The study focused on adults aged 18 to 65 who were triaged as semi-urgent or non-urgent and had access to smartphones. Participants were required to have at least one existing health-risk behaviour and access to a smartphone.
The intervention used the AWARD model—Ask, Warn, Advise, Refer, and Do-it-again—delivered via a brief telephone call at discharge, followed by weekly WhatsApp or WeChat messages for six months. Researchers compared this to a control group that received only brief telephone advice. This method paired short telephone consultations with support via mobile instant messaging. The study was designed as an assessor-blinded randomized controlled trial.
The findings revealed that at the six-month mark, 30.1% of the intervention group achieved self-reported abstinence from at least one health-risk behavior, compared to 19.9% in the control group. Physical inactivity saw the most significant improvement, with 31.7% of the intervention group reporting abstinence versus 16.2% of the control group. The intervention group showed a significantly higher likelihood of reducing risky behaviours at both the six-month and 12-month intervals. Statistical analysis confirmed these improvements were significant.
While the digital support showed short-term benefits, the study noted that the effect was not sustained at the 12-month follow-up. This suggests that while telephone and messaging interventions are powerful tools for immediate behavior change, longer-term maintenance strategies may be necessary to ensure lasting health improvements. The researchers concluded that multicenter trials with longer follow-up periods are warranted. Such studies would help evaluate the long-term effectiveness of these digital strategies.
