A Pilot Randomized Controlled Trial of Text Messages to Improve Well-Child Visit Attendance After No-Show.

OBJECTIVE: Evaluate the effectiveness of text messages to systematically engage parents/guardians ("caregivers") to reschedule a well-child visit (WCV) that was missed ("no-show") and attend that rescheduled WCV visits. METHODS: Patients <18 years in one of five pediatrics or family medicine clinics, in one health system in the Southeast US, were eligible. Patients without a rescheduled WCV after a no-show were randomized into intervention (text messages) or care-as-usual comparison, stratified by language (English/Spanish). Enrollment occurred May-July 2022. Up to three text messages were sent to caregivers one week apart via REDCap and Twilio, advising how to reschedule the missed appointment by phone or health portal. Primary outcomes were 1) rescheduling a WCV within 6 weeks of no-show and 2) completing a rescheduled WCV within 6 weeks. Risk differences (RD) and odds ratios (OR) were used to evaluate the effect of text messages. RESULTS: Seven hundred and twenty patients were randomized and analyzed (texts: 361, comparison: 359). The proportion rescheduling WCV after text versus usual care was English: 18.85% versus 15.02%, respectively, and Spanish: 5.94% versus 8.14%, with overall RD+ 1.98% (95% CI: -1.85, 5.81) and OR 1.21 (95% CI: 0.79, 1.84; P-value .38). Completed WCV rates in text or usual care were English: 13.08% versus 6.59%, and Spanish: 5.81% versus 5.94% with texts associated with RD+ 2.83% (95% CI: 1.66, 4.00) and OR 1.86 (95% CI: 1.09, 3.19). CONCLUSION: Text message follow-up after a no-show WCV may positively impact attendance at WCVs rescheduled in the subsequent 6 weeks. TRIAL REGISTRATION: ClinicalTrials.gov NCT05086237.
