RESUMO
OBJECTIVE: To ascertain and develop recommendations for analgesic management, discharge planning and further healthcare utilisation of adults presenting to an Australian tertiary ED with radicular or low back pain (LBP). METHODS: This prospective cohort study included adults presenting with non-specific LBP or radicular pain to an Australian tertiary ED. Participants with trauma/cancer-related pain, and those requiring hospital admission or surgical interventions were excluded. The primary outcome was pharmacological and non-pharmacological management delivered in ED, retrospectively collected via electronic medical records. The secondary outcomes include discharge management use, and changes made due to post-discharge healthcare utilisation, as observed by weekly telephone questionnaires over 4-weeks follow-up. RESULTS: Of the 100 participants recruited, 94 completed follow-up. In ED, pharmacological management was received by 85%, including opioids (62%) and non-steroidal anti-inflammatory drugs (NSAIDS, 63%). Non-pharmacological management was received by 73%, including patient education (71%) and exercise prescription (37%). In the first-week post-discharge, changes to initial discharge plan occurred in 50%, mostly carried out by GPs (76%). Over the follow-up period, 51% received additional investigations/referrals. Pharmacological use decreased by 38% and non-pharmacological use decreased by 10%. 16% of opioid-naïve patients continued using opioids 4-weeks post-discharge. CONCLUSION: ED presentations for LBP were more often treated pharmacologically than non-pharmacologically, with opioids commonly prescribed and NSAIDs potentially under-utilised. Post-discharge, additional investigations/referrals, discharge analgesia reductions and maintenance of non-pharmacological management were common. Opioid initiation as a result of LBP presentations, signifies a potential 'gateway' towards unintentional long-term use. Key study findings form our nine recommendations to inform ED LBP pain management.
