A study tested various SMS invitations to encourage participation in digital Health Checks among Londoners aged 40-74 without cardiovascular disease. The four-week study included 1700 individuals and utilized a six-arm randomized controlled trial (RCT) design. The uptake rates varied, with the shortest SMS yielding a 20% response rate compared to 12% for the standard SMS. Multi-modal reminders, notably postal reminders, proved more effective, increasing participation substantially. Incorporating digital options into traditional services could enhance overall healthcare screening uptake.
Digital screening may divert lower-risk individuals to online options and offer acceptable alternatives for higher-risk non-responders, suggesting a mixed-modality approach may enhance uptake.
Uptake varied significantly across different SMS reminder strategies, highlighting an increase from 12% with standard SMS to 20% with the shortest SMS, demonstrating the impact of communication length.
The most effective reminder method proved to be postal reminders, achieving a +7% increase in uptake compared to +3% from SMS reminders, showcasing the value of multi-modal communication.
Incorporating digital care into in-person services has the potential to boost screening uptake by 10%, raising total participation rates from 50% to 60%.
