| アブストラクト | OBJECTIVES: the purpose of this study was to evaluate the likelihood that the presence of certain medical conditions in older ambulatory patients are associated with the risk of developing a new pressure ulcer. DESIGN: a cohort study. SETTING AND SUBJECTS: a large outpatient record database from the United Kingdom called the General Practice Research Database. METHODS: the frequency of disease was reported as simple percentages and the associations between the medical conditions and the development of a pressure ulcer as instantaneous rate ratios. RESULTS: we studied 75,168 older individuals. Pressure ulcers occurred in 1,211 individuals. The medical conditions that were significantly associated with the development of a pressure ulcer after adjustment were: Alzheimer's disease, congestive heart failure, chronic obstructive pulmonary disease, cerebral vascular accident, diabetes mellitus, deep venous thrombosis, hip fracture, hip surgery, limb paralysis, lower limb oedema, malignancy, malnutrition, osteoporosis, Parkinson's disease, rheumatoid arthritis, and urinary tract infections. Angina, hypertension, and pneumonia were inversely associated with the development of a pressure ulcer. CONCLUSIONS: it is important that physicians recognise that patients with many medical conditions may be at higher risk for pressure ulcers so that even in the ambulatory care environment appropriate prevention and detection strategies can be directed towards the patients who are most likely to benefit. |
