Abstract

Some elderly persons develop high-grade decubitus ulcers, whereas others with comparable risk factors do not. In Germany, forensic pathologists are increasingly confronted by situations that necessitate an expert opinion on whether prevention of decubitus ulcers has been neglected in cases of suspected malpractice. This investigation was carried out in an attempt to identify risk factors for decubitus ulcers. We performed a postmortem case–control study in elderly persons who developed high-grade decubitus ulcers from 6 months to 14 days before death. Deceased with decubitus ulcers graded 3 or higher and controls at comparable risk were examined before cremation. After written informed consent had been obtained from the nearest living relatives, all available nursing and medical records of the deceased were thoroughly evaluated. Decubitus ulcer cases and controls were matched according to age, gender, immobility, and cachexia. One-hundred cases of decubitus ulcers with 71 grade 3 decubitus ulcers and 29 grade 4 decubitus ulcers were compared with 100 controls with 27 decubitus ulcers graded 2 or lower and the maximal risk as assessed by the Norton scale. The mean age was 86 years, 80% were females, 86% were bedridden, and cachexia was found in 66%. The individuals with decubitus ulcers were more often severely disabled, had more immobility of joints, and were more often under treatment with antidepressive and/or sedative drugs (e.g., opioid analgesics, neuroleptics, benzodiazepines). Patients' impaired ability or unwillingness to comply or cooperate with preventive and therapeutic measures was more often recorded in cases of decubitus than in the control group. There was no evidence that supplementary nutrition or use of preventive pressure relief and protective devices differed between the decubitus cases and the controls.
