Opioid Treatment Is Associated with Recurrent Healthcare Visits, Increased Side Effects, and Pain
Abstract
Introduction: Pain is a major driver of visits to the emergency department (ED). Clinicians must consider not only the efficacy of treatment options but also subsequent healthcare utilization and patient-centered outcomes such as side effects from prescribed medications. Our goal in this study was to determine whether there was an association between acute pain treatment regimen (opioids, intranasal non-steroidal anti-inflammatory drugs [NSAIDs], or both) and unscheduled healthcare visits following ED discharge.
Methods: This study was a secondary analysis of the Acute Management of Pain from the Emergency Department (AMPED) prospective, observational cohort study. We used Cox proportional hazards analysis to assess the relationship between treatment regimen and time to first unscheduled healthcare visit. Repeated measures logistic regression analyses were used to determine the relationship between treatment regimen and any unscheduled visits, and to evaluate whether this relationship was mediated by pain severity and/or medication side effects.
Results: Of 831 total enrolled participants, 141 (16.9%) experienced an unplanned healthcare visit within five days of ED discharge. A majority of these visits happened one day after the ED visit. Those who were treated with intranasal NSAIDs only were less likely to have an unscheduled healthcare visit compared to those who received opioids only, with an adjusted odds ratio (AOR) of 0.63. The higher odds of unscheduled healthcare visits with opioids were mediated by both the presence of side effects and higher pain levels, with AORs of 2.24 and 1.33, respectively.
Conclusion: Opioid treatment for acute pain is associated with increased unscheduled healthcare visits compared to those treated with intranasal ketorolac. This difference can be explained by higher levels of ongoing pain and greater medication side effects.
