Cellulitis in the Emergency Department: A prospective cohort study with patient-centred follow-up.

OBJECTIVE: There is substantial practice variation in the management of cellulitis with limited prospective studies describing the course of cellulitis after diagnosis. We aimed to describe the demographics, clinical features (erythema, warmth, swelling and pain), patient-reported disease trajectory and medium-term follow-up for ED patients with cellulitis. METHODS: Prospective observational cohort study of adults diagnosed with cellulitis in two EDs in Southeast Queensland, Australia. Patients with (peri)orbital cellulitis and abscess were excluded. Data were obtained from a baseline questionnaire, electronic medical records and follow-up questionnaires at 3, 7 and 14 days. Clinician adjudication of day 14 cellulitis cure was compared to patient assessment. Descriptive analyses were conducted. RESULTS: Three-hundred patients (mean age 50 years, SD 19.9) with cellulitis were enrolled, predominantly affecting the lower limb (75%). Cellulitis features showed greatest improvement between enrolment and day 3. Clinical improvement continued gradually at days 7 and 14 with persistent skin erythema (41%) and swelling (37%) at day 14. Skin warmth was the feature most likely to be resolved at each time point. There was a discrepancy in clinician and patient assessment of cellulitis cure at day 14 (85.8% vs. 52.8% cured). CONCLUSIONS: A clinical response of cellulitis features can be expected at day 3 with ongoing slower improvement over time. Over one third of patients had erythema or swelling at day 14. Patients are less likely than clinicians to deem their cellulitis cured at day 14. Future research should include parallel patient and clinician evaluation of cellulitis to help develop clearer definitions of treatment failure and cure.

The Headache in Emergency Departments study: Opioid prescribing in patients presenting with headache. A multicenter, cross-sectional, observational study.

OBJECTIVE: To describe the patterns of opioid use in patients presenting to the emergency department (ED) with nontraumatic headache by severity and geography. BACKGROUND: International guidelines recognize opioids are ineffective in treating primary headache disorders. Globally, many countries are experiencing an opioid crisis. The ED can be a point of initial exposure leading to tolerance for patients. More geographically diverse data are required to inform practice. METHODS: This was a planned, multicenter, cross-sectional, observational substudy of the international Headache in Emergency Departments (HEAD) study. Participants were prospectively identified throughout March 2019 from 67 hospitals in Europe, Asia, Australia, and New Zealand. Adult patients with nontraumatic headache were included as identified by the local site investigator. RESULTS: Overall, 4536 patients were enrolled in the HEAD study. Opioids were administered in 1072/4536 (23.6%) patients in the ED, and 386/3792 (10.2%) of discharged patients. High opioid use occurred prehospital in Australia (190/1777, 10.7%) and New Zealand (55/593, 9.3%). Opioid use in the ED was highest in these countries (Australia: 586/1777, 33.0%; New Zealand: 221/593, 37.3%). Opioid prescription on discharge was highest in Singapore (125/442, 28.3%) and Hong Kong (12/49, 24.5%). Independent predictors of ED opioid administration included the following: severe headache (OR 4.2, 95% CI 3.1-5.5), pre-ED opioid use (OR 1.42, 95% CI 1.11-1.82), and long-term opioid use (OR 1.80, 95% CI 1.26-2.58). ED opioid administration independently predicted opioid prescription at discharge (OR 8.4, 95% CI 6.3-11.0). CONCLUSION: Opioid prescription for nontraumatic headache in the ED and on discharge varies internationally. Severe headache, prehospital opioid use, and long-term opioid use predicted ED opioid administration. ED opioid administration was a strong predictor of opioid prescription at discharge. These findings support education around policy and guidelines to ensure adherence to evidence-based interventions for headache.

Rural and Remote Intubations in an Australian Air Medical Retrieval Service: A Retrospective Cohort Study.

OBJECTIVE: Critically unwell patients in rural and remote areas of Queensland, Australia, often require airway management with rapid sequence intubation before retrieval to a tertiary center. Retrieval Services Queensland coordinate retrievals and support rural hospitals, including via telehealth. This study compared the demographics of patients intubated by a retrieval team including a LifeFlight Retrieval Medicine doctor with those intubated by the local hospital team. METHODS: This was a retrospective cohort study of patients intubated in hospitals in Queensland, Australia, requiring subsequent air medical retrieval between January and December 2019. The data collected included the time of day, mission priority, geographic location, diagnosis, and failure/assistance with intubation. Descriptive statistics were complemented by regression analyses. RESULTS: In 2019, 684 patients were intubated in hospitals in Queensland, Australia, requiring air medical retrieval by a team including a LifeFlight Retrieval Medicine doctor. One hundred thirty-one (19.2%) were intubated by the retrieval team, and 553 (80.8%) were intubated by the hospital team. In the most rural and remote areas, 64 (43.2%) of the patients were intubated by the retrieval team compared with 84 (56.8%) by the hospital team. CONCLUSION: A retrieval team is more likely to intubate patients in remote hospitals in Queensland, Australia. Remote hospitals should be given preference for dispatch of the retrieval team for assistance with critical patients.
