Improving Follow-Up for Discharged Emergency Care Patients

Telemedicine is a modern field of clinical medicine that strives to incorporate telecommunication and information technology for diagnosing and managing health care at a distance. Interventions range from telephone reminders to remote physician consultation by streamed by webcam. Simple technology such as telephone and SMS texting are becoming common forms of communication and may improve patient adherence and engagement. Automated telephone appointment reminders have improved adherence with follow-up appointments in some settings, but have mixed results in patients discharged from the emergency department (ED). Increasing adherence to follow-up care has been a priority in the ED to improve patient outcomes and reduce unnecessary future visits.

An electronic intervention platform has been developed by Epharmix (now HealthSignal), uses SMS text messaging for adherence tracking and data collection applications, to supplement clinical care. Specific messages include: proactively asking patients or a designated patient advocate if the patient has experienced a medical event; requesting specific care-related information; and providing health care education. Patients receiving the messages are also provided with key contact information for their designated health care provider to promote patient engagement, as well as prompt and appropriate medical follow-up care. The service will maintain both a dedicated SMS and phone line for recording events or adverse reactions. Events designated as critical prompt a phone call from nursing staff. Overall, this study aims to determine whether an electronic intervention system that sends SMS text messages will improve adherence to follow-up appointments after an ED visit.

Patients age 18 years or older at Barnes Jewish Hospital are included in this study. We conducted a prospective randomized open, blinded end-point (PROBE) trial of 278 adult patients discharged from the ED and referred to a provider for follow-up care. Participants in the intervention arm received a self-scheduling text or phone message using the Epharmix (now HealthSignal) platform that connected them to their referral provider to schedule a follow-up appointment and sent them appointment reminders. Those in the control arm received standard-of-care written instructions to contact listed referral providers. The primary outcome was time to appointment. The secondary outcome was time to return visit to the ED.
