RESUMEN
OBJECTIVES: This study describes the prevalence of pain in trauma patients 1 year after hospital admission and investigates separately health-related quality of life (QoL) for patients suffering severe pain and for those without pain. Moreover, psychosocial factors are examined for their impact on pain. METHODS: Patients were contacted 12 months after admission in order to complete the following questionnaires: Medical Outcomes Study 36-Item Short Form Health Survey (SF-36), Trauma Outcome Profile (TOP), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Impact of Event Scale-Revised (IES-R) and additional questions concerning satisfaction, work and financial status. Relevant pain at follow-up was defined as <80 points on the pain subscale of the TOP. RESULTS: Two hundred and twenty patients were included. The Injury Severity Score (ISS) ranged from 1 to 41. Fifty-three percent (53 %) of patients suffered a severe trauma (ISS > 15). One year after injury, 55 % of patients had relevant pain according to the TOP. Patients with pain were older (41.4 vs. 34.4 years, p = 0.003) and had slightly more severe injuries (ISS 17.1 vs. 14.9, p = 0.115). There were significant differences between pain and no-pain patients on all domains of QoL (p < 0.001) and on the BDI, STAI and IES-R (p < 0.001). Pain patients more often experienced a stressful event and job-related and financial difficulties. Multivariate logistic regression analysis revealed post-traumatic stress disorder (PTSD) as the strongest predictor for pain [odds ratio (OR): 4.38, p = 0.015], followed by a stressful life event (OR: 4.08, p = 0.001). DISCUSSION: Pain is strongly associated with psychosocial complaints 1 year after trauma. For the treatment of pain following a traumatic event, social reintegration and emotional regulation by means of occupational rehabilitation and psychotherapy should receive more attention.
RESUMEN
PURPOSE: Due to an increasing number of survivors after multiple injuries in Western countries, the health-related quality of life (QoL) is considered to be an important outcome parameter. Up to now, measuring instruments used in this field lacked validity and comparability. Within 6 years, our working group developed a new modular instrument, called the Polytrauma Outcome (POLO) chart. This study documents the validation of the trauma-specific module specifically designed for trauma patients, the Trauma Outcome Profile (TOP). METHODS: A total of 172 multiply injured patients (mean Injury Severity Score [ISS] 26.7) recruited from eight trauma centres participating in the German Trauma Registry were compared with 166 marginally injured patients (mean ISS 3.9). The mean follow-up was 24.2 and 26.4 months, respectively. The validation questionnaires used were the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), Impact of Event Scale-Revised (IES-R), Social Support Questionnaire (F-SOZU-K-22), Barthel Index of Activities of Daily Living (ADL) and the Short Form Health Survey (SF-36). RESULTS: The internal consistency of the different dimensions of QoL assessed with the TOP was good. Factor analysis provides evidence of the construct validity of the questionnaire. Correlation with external measures gives evidence of criterion validity for the various dimensions of QoL and similar exceedance of proposed cut-off points within TOP and external measures is verified. CONCLUSION: The TOP module is a reliable and valid instrument to assess health-related QoL in patients with multiple injuries. It can be used stand-alone or as part of the POLO chart together with the Glasgow Outcome Scale (GOS), the EuroQoL and the SF-36 as a regular systematic follow-up instrument.
