Background and Objectives: There is scarce data about the epidemiology, clinical features, investigations, diagnosis, treatment, and outcome in patients attending Singapore emergency departments (EDs) with nontraumatic headache. We sought to describe these characteristics of adult patients presenting to the ED with a primary complaint of headache. Materials and Methods: We performed a cross-sectional study on adult patients with nontraumatic headache over 4 consecutive weeks from 18 March 2019 to 14 April 2019 across four EDs in Singapore. Exclusion criteria were history of head trauma within 48 h of presentation, missing records, interhospital transfers, representation with the same headache as a recent previous visit and headache as an associated symptom. Results: During the study period, 579 patients (representing 1.8% of the total ED census) comprising 55.3% males and with a median age of 36 years presented to the four Singapore EDs with a primary complaint of nontraumatic headache. Paracetamol (41.5%), non-steroidal anti-inflammatory drugs (34.4%) and tramadol (31.5%) were the three commonest analgesics used either singly or in combination. Prochlorperazine (22.9%) and metoclopramide (17.4%) were frequent anti-emetic adjuncts. One-third of patients had computed tomography of the brain performed, which found abnormalities among 20.9% of them. ED diagnoses of primary headache conditions were made in 73.6% of patients. Conclusions: Primary headaches constituted most ED headache diagnoses. ED imaging of selected patients yielded a relatively high pick-up rate for significant intracranial abnormalities. Opioid use for symptomatic relief of headaches in the ED was found to be high, underscoring the need for improvement in headache analgesia relief practices in the ED.

Aims: Ultrasound guided nerve blocks have been shown to be an effective analgesia option for patients with hip fracture. An education program was developed to train Emergency Department doctors and it received positive feedback from partici-pants who demonstrated competency after the training. We aimed to evaluate the education program at the behavioral level of the Kirkpatrick Model by determining the translation of training to practice of ultrasound guided nerve blocks in patients with a hip fracture at the Emergency Department. Materials and methods: A retrospective review of medical records was carried out from 18 August 2018 to 31 December 2020. Data on patient demographics, type of hip fracture, pain score, analgesia pro-vided and complications were collected using a standardized form and analyzed. Results: Among 634 patients, their median age was 79 years old (Interquartile range (IQR): 70 to 85) and 416 (65.6%) were female. The median pain score was 6 (IQR: 5 to 8) and analgesia was provided for 561 (88.5%) patients. Analgesia was administered most frequently via the intravenous route (n=407, 72.5%) and tramadol (n=293, 52.2%) was most commonly used. Ultrasound guided nerve block was performed in 26 (4.7%) patients – all were performed successfully without complications. The utilization increased from 1.0% before to 4.7% after the conduct of the training workshops (p=0.16). Conclusion: A significant gap still exists in the translation of training to practice. Barriers must be identified and overcome so that ultimately, the education program can bring about an organizational impact to benefit patients and improve their outcomes.
