Prevalence, Location, and Interference With Daily Life of Chronic Pain in Long-Term Survivors After Discharge From a Tertiary Emergency Center.

Abstract

Background This study aimed to investigate the prevalence, location, and characteristics of new-onset chronic pain by using a new definition in long-term survivors after discharge from a tertiary emergency center. Materials and methods We conducted a single-center ambidirectional cohort study from January to May 2022. A survey of patients was conducted by postal mail two to 2.5 years after their discharge from a tertiary emergency center. We used the Brief Pain Inventory to investigate chronic pain parameters, and the painDETECT questionnaire to investigate neuropathic pain. Patient information during hospitalization was collected retrospectively from medical records. Results The survey was sent to 78 patients, 63 (81%) of whom responded and were included in the analysis. Nine of the 63 patients (14%) had new-onset chronic pain. Of these, six (67%) had chronic pain of moderate or severe intensity which interfered with daily life. The most frequent location of chronic pain was the foot/ankle (n=4, 44%). Neuropathic pain was present in four (44%) patients with new-onset chronic pain. Conclusion New-onset chronic pain may occur for up totwo to 2.5 years after discharge from a tertiary emergency center, and this may interfere with daily life. Therefore, a follow-up system for chronic pain is warranted.
