Implementations of a text-message intervention to increase linkage from the emergency department to outpatient treatment for substance use disorders.

AIM

To determine acceptability and explore potential usefulness of a text messaging (SMS) program aimed at increasing attendance at outpatient treatment for substance use disorders (SUD) after emergency department (ED) referral.

METHOD

A retrospective analysis of 377 adult patients from 2 urban EDs seeking treatment for SUD (opioids (n = 168), alcohol (n = 188), benzodiazepines (n = 21)) referred to outpatient treatment and offered an SMS program which included daily (1) motivational messages focused on positive thinking, (2) ecological momentary assessments (EMA) related to craving with tailored behavioral strategy messages, (3) EMA of drug use with tailored feedback to reduce abstinence violation effects, and (4) reminders about treatment location and phone number. We assessed acceptability by examining opt-in rates, EMA completion rates over the first week and end-of-program qualitative feedback. We assessed how individuals who opt in differ in outcomes from those who opt out by examining rates of outpatient SUD treatment attendance recorded from the medical record.

RESULTS

167 patients (44%) opted in to the SMS program. Over 7 days, around 33% of EMA were completed. Median helpfulness score was 8 (IQR 6 to 10) out of 10 and 84% would recommend the SMS program to someone else. Individuals who opted in to the SMS program had higher rates of SUD treatment initiation than individuals who did not opt-in (70.7% vs. 40.9%).

CONCLUSIONS

We found evidence supporting acceptability and potential usefulness of an automated text message program to assist treatment attendance for some individuals with SUDs discharged from the ED. A controlled trial is needed to examine whether SMS program exposure is associated with improved treatment attendance compared to standard care.
