AbstractBackground and aims:Trauma is one of the most common causes of morbidity and mortality in people of working age. Following surgery, approximately 10% of patients develop persistent postsurgical pain. Chronic pain is a complex phenomenon that can adversely affect quality of life and is associated with psychiatric conditions such as anxiety and depression. Pharmacological treatment is normally insufficient to fully alleviate chronic pain and improve functional capacity, especially in the long term. The appropriateness of opioid treatment in chronic non-cancer pain has become increasingly examined with high numbers of serious side effects including drug dependency and death. The present study was based on clinical observations suggesting that a problematic opioid use can be initiated during trauma care, which implies the importance of evaluating opioid therapy and its effect on trauma patients. Specific attention is given to patients with known psychiatric conditions which may render them more vulnerable to develop problematic opioid use. The aim of this observational study was to broadly characterize patients referred to a pain specialist after severe trauma regarding their trauma type, psychiatric co-morbidity, and opioid prescription pattern. This was done to tentatively investigate possible risk factors for long-term opioid use following trauma.Methods:Trauma patients referred to the Pain Center at Karolinska University Hospital, Sweden (n=29) were recruited for the study over a period of 2 years. Demographic information, trauma-related data as well as psychiatric diagnoses and pharmacological prescriptions were retrieved from the registry SweTrau and electronic medical records.Results:Among the 29 participants (age range 21–55 years, median=34; 76% male), 14 (48%) were prescribed opioids at least once during the 6-months period preceding the trauma. For 21 patients (72%) opioids were prescribed 6 months after the trauma. One year after the trauma, 18 patients (62%) still had prescriptions for opioids corresponding to daily use or more, and two other patients used opioids intermittently. Twenty patients (69%) had psychiatric diagnoses before the trauma. According to the medical records, 17 patients (59%) received pharmacological treatment for psychiatric conditions in the six months period preceding the trauma. During the follow-up period, psychiatric pharmacological treatment was prescribed for 27 (93%) of the patients.Conclusion and implications:For most of the participants opioids were still being prescribed one year after trauma. The majority presented with psychiatric co-morbidity before trauma and were also prescribed psychiatric medication. Findings support the notion that patients with a complex pain situation in the acute phase following trauma are at risk for prolonged opioid prescription. These results, although tentative, point at psychiatric co-morbidity, opioid use before trauma, high injury severity, extensive surgery and extended hospital stay as risk factors for prolonged opioid prescription after severe trauma. This study is purely observational, with a small sample and non-controlled design. However, these data further emphasize the need to identify patients at risk for developing problematic long-term opioid use following trauma and to ensure appropriate pain treatment.
