Has anyone paired REDCap pre-screeners with a HIPAA-compliant SMS tool for patient outreach? After switching to REDCap + Twilio texting and REDCap eConsent, we cut time-to-consent from 12 to 5 days and reduced missed prescreen calls by about 30%; I’d love your tips on message cadence, opt-in wording, and how you log coordinator touchpoints without duplicating work.
We’re on REDCap + Twilio too; cutting from 12 to 5 days tracks with ours. Cadence that worked: day 0 invite, 24h noon reminder, day 3 final — more than 3 texts got us filtering, ; opt-in that tested best: “Can we text you about [study]? Reply YES to consent; STOP anytime.” To avoid duplicate touchpoint notes, we log in a single repeating “Contact Log” instrument with a default [now] timestamp so coordinators just pick an outcome; Twilio’s tips here helped: https://www.twilio.com/docs/messaging/guidelines — how are you handling weekend sends?
Carrier filtering drove me nuts until we registered A2P 10DLC and used a Twilio Messaging Service — after that, delivery jumped and our 12→5 day improvement held: Programmable Messaging and A2P 10DLC | Twilio. To avoid duplicate logging, we use a repeating “Contact Log” instrument and let inbound SMS auto-create entries via the Twilio webhook to the project’s SMS survey; coordinators just add calls/voicemail notes. Opt‑in text that passes review for us: “Reply YES to join study texting (about 3 msgs/week); STOP to opt out; HELP for help” — are you sending from a long code or verified toll‑free?
Quick win: send a branded-domain survey link and feed Twilio status callbacks back to REDCap so an “engaged” flag halts the remaining texts and coordinators don’t have to re-enter notes. My opt-in line is “Reply YES to get up to 3 study texts; STOP to stop,” with 8p–8a quiet hours to keep complaints down. @lucas15 have you tried branded links, and did it bump click-through?
We saw a bump by setting quiet hours and auto-detecting timezone from ZIP so reminders don’t land at 6am; engagement rose without adding more texts. For opt-in, we do a quick double confirm: first SMS says “Reply YES to proceed — reply STOP to opt out; HELP for info,” then we send the pre-screener link to keep SMS PHI-free. To avoid duplicate logging, a tiny webhook updates a single “last touch + outcome” field from both inbound and delivery events, and if filtering pops up, @lhill81, verified toll-free has been steadier than local numbers.
Nice 12→5 drop — the biggest unlock for us was piping Twilio Studio webhooks into a repeating REDCap “Touchpoints” instrument via the API, so every text/click/delivery lands on the same record where coordinators add brief call notes. Cadence-wise, we trigger a follow-up 90 minutes after the first SMS only if we see a “clicked but no submit” event, then a final nudge at 72 hours; if your API access is tight, a nightly CSV export/import from Twilio logs is a workable fallback.
