Risk factors and predictors of prolonged hospital stay in the clinical course of major amputations of the upper and lower extremity a retrospective analysis of a level 1-trauma center

PurposeThe objective was to analyze the treatment and complications of the patients after a major amputation of the upper and lower extremities. Risk factors and predictors of a prolonged hospital stay should be outlined.MethodsThis is a retrospective study of a national Level-1 Trauma center in Germany. In a 10-year period, patients were identified by major amputations in the upper and lower extremities. The medical reports were considered and the results were split into four main groups with analysis on basic-, clinical data, the course on intensive care unit and the outcome. A recovery index was established. The patients' degree of recovery was summed up. Statistical analysis was performed.Results81 patients were included. A total of 39 (48.1%) major amputations were carried out on the lower leg and 34 (42.0%) involved the thigh. There were two instances (2.5%) of hip joint disarticulation. 6 major amputations were done on the upper extremities (n = 3 on the upper arm, n = 3 on the forearm). 13.83 +/- 17.10 days elapsed between hospital admission and major amputation. The average length of hospital stay was 38.49 +/- 26,75 days with 5.06 +/- 11.27 days on intensive care unit. Most of the patients were discharged home followed by rehabilitation. A significant correlation was found between the hospital length of stay and the increasing number of operations performed (p = 0.001). The correlation between the hospital length of stay and the CRP level after amputation was significant (p = 0.003).ConclusionsMajor amputations in trauma patients lead to a prolonged stay in hospital due to severe diseases and complications. Especially infections and surgical revisions cause such lengthenings.
