Effect of Telephone Call and Text Message Reminders on Patient Return to Acupuncture Follow-Up Treatment: A Pilot...

Background: Telephone calls and text messages function as cues to elicit patient behavior. Objective: We tested the effect of telephone call and text message reminders on patient return to acupuncture follow-up treatment. Design: This is a randomized controlled trial. Setting and Subjects: We recruited adults visiting an acupuncture clinic for a new treatment consultation. Our sample contained 120 participants with 40 per study group. Interventions: Consenting patients were randomized to 1 of 3 study exposures: single voice call, single text message, or treatment as usual (TAU/no reminder). Exposures were sent 3 days after patient's initial treatment. Outcome Measures: Data from clinic charts were abstracted to quantify the absence/presence of a follow-up treatment return in the 30 days after initial treatment. Participants provided self-report of pain symptoms 10 and 30 days after initial treatment on the pain disability index (PDI) to measure change in PDI by return to follow-up treatment as a secondary outcome. Results: Telephone call (56%, P = 0.98) and text message (57%, P = 0.99) groups showed similar proportion of follow-up treatment returns compared with TAU group (57%). Presence of a follow-up appointment scheduled at the initial treatment predicted patient treatment return (odds ratio: 5.87, P < 0.01). Follow-up treatment return predicted reduced PDI scores at day 30 (β = -3.09, P = 0.02). Conclusions: Adding a 1-time telephone call or text message reminder to standard clinic practice did not improve patient return to acupuncture follow-up treatment within 30 days of initial treatment. Scheduling a future appointment date at initial treatment visit may improve treatment return, and return attendance appears protective of pain disability in the short term.
