P149: Benign headache management in Alberta emergency departments: a chart review study to explore gaps in practice

Abstract

Introduction: Variation in medication management and image ordering for HA presentation to emergency departments (ED) has been documented. This study examined benign HA (i.e., migraine, cluster, tension) management in order to identify the consistency and appropriateness of HA management in EDs in Alberta. Methods: Patients were identified by primary discharge diagnosis in the National Ambulatory Care Reporting System using ICD-10-CA codes for benign HA (G43, G44, R51). Patients presenting to study sites from January 1, 2017 to September 30, 2017 were eligible for inclusion, provided they were adults (≥18 years), were not transferred from another institution or directly admitted to a service, and had an active HA at presentation. One hundred eligible patients were randomly selected for chart review. Data were extracted on standardized forms. Preliminary data on 50 patients (n = 150) from three Edmonton study sites is presented. Results: Most patients arrived to the ED via personal transportation (93%) and were assigned a Canadian Triage and Acuity Scale (CTAS) score of 3 (71%). The majority of patients were female (75%); mean age was 45 years (standard deviation: 18). Triage pain score was not documented for 21%. When documented, pain scores were most frequently between 4 and 7 (49%). Nearly 10% of patients left without being seen. For those who were assessed, physicians most frequently used ketorolac and metoclopramide as first or second line treatments or as a combination treatment. Consults were infrequent (14%). Nearly half of the patients (47%). had computed tomography (CT) in the ED. Pain re-assessment was completed for 69% of patients. Most patients were discharged from the ED (88%) and given some form of discharge instruction (78%). The most common instructions were to return to ED as needed (45%) and follow-up with their primary care physician (28%). Across all patients, 13% returned to the ED with headache within 30 days. Conclusion: Physicians treat patients with benign headaches appropriately and hospitalization is infrequent; however, one in eight patients relapse. Missing pain scale documentation reveals a potential problem for ED clinicians in assessing management effectiveness and ensuring patients leave the ED following pain relief. Half of the patients received a CT scan, highlighting the urgent need for an intervention to address CT overuse for patients with benign HA within this geographic region.
