Comparison of Emergency Department Attendance After Emergency Care Recommendations from Nurse and Online eHealth...

Online self-triage is a newer eHealth modality, and there is a paucity of research on patient adherence to self-triage recommendations. We evaluated patient compliance with online self-triage guidance to seek emergency care and compared to nurse-triage adherence rates.

We reviewed primary care empaneled patients who had either nurse phone triage or an online self-triage encounter that resulted in an emergency care recommendation between January 1, 2023, and November 30, 2024. Patients triaged for mood concerns, abdominal pain, chest pain, constipation, cough, and diarrhea were included. We reviewed whether patients had an emergency department visit within 24 h of their triage encounter. For self-triage encounters, we also examined whether patients called nurse triage within 24 h of their self-triage encounter.

There were 689 self-triage and 2,385 nurse triage encounters with an emergency care endpoint. Adherence to the emergency care recommendation was substantially lower after self-triage (22%) than after nurse triage (61%). Patients who underwent nurse triage were significantly more likely to seek emergency care than those who self-triaged (odds ratio of 5.4 [95% CI: 4.5-6.6] p < 0.001). Both male and female patients were less likely to follow emergency care recommendations after self-triage compared to nurse triage (p < 0.001). There were 258 patients with an emergency care endpoint from self-triage who chose to call nurse triage (median time between encounters of 16 min). Only 78 (30.2%) also received an endpoint recommendation for emergency care, and 73% of those patients sought emergency care within 24 h.

Patient compliance with online self-triage recommendations to seek emergency care was poor and significantly less than nurse triage. Follow-up calls to nurse triage led to higher compliance. Health systems using online symptom checkers should consider employing mechanisms to follow up on emergency care recommendations. Further research should elucidate factors that contribute to patients' willingness to follow care recommendations.
