Study ObjectivePrimary care (PC) follow-up for discharged emergency department (ED) patients provides patients with further medical attention. We conducted a pilot randomized controlled trial to determine whether using a freely-available physician appointment-booking website results in higher self-reported PC follow-up.MethodsWe randomized discharged patients whom treating physicians determined PC follow-up was important and who possessed health insurance but had no PC provider to one of three groups: (1) a PC appointment booked through the booking website prior to ED discharge; (2) written information on how to use the booking website; or (3) usual care (i.e. standard follow-up instructions). We phoned subjects two weeks after the ED visit to determine whether they had completed a PC follow-up visit. We also asked subjects about their satisfaction with obtaining a PC appointment, satisfaction with the ED visit, symptom resolution and subsequent ED visits. The self-reported PCP follow-up rate was compared among the study groups by estimating the risk difference (RD) and 95% CI between usual care and each intervention group.Results272 subjects were enrolled and randomized and 68% completed the two-week telephone follow-up interview. The self-reported PCP follow-up rate was higher (52%) among subjects whose appointment was booked on the website before ED discharge (RD = 16%; 95% CI -1%, 34%) and lower (25%) for subjects who received booking website information (RD = 13%; 95% CI -32%, 7%) compared to subjects (36%) in the usual care group. A higher percentage of subjects in the booking group were more likely to report being extremely or very satisfied with obtaining a PC appointment (78%) compared to those who received booking website information (54%) or usual care (40%).ConclusionAmong ED patients that providers judged PC follow-up is important, using a booking website to schedule an appointment before ED discharge resulted in a higher but not statistically significant self-reported PC follow-up rate. This intervention warrants further investigation in a study with a larger sample size and objective follow-up visit data.Copyright © 2019 Elsevier Inc. All rights reserved.
