We read with interest the report by Perneger et al1 regarding risk factors for medically inappropriate admissions to a Swiss department of internal medicine. Of the 76 patients whose admissions were deemed inappropriate, 53 were admitted for a diagnostic workup. Reasons for admission of the remaining 23 patients were not given, but because the receipt of informal care was an important risk factor in the logistic regression model, we assume that many of these admissions were for caregiver strain, or what is sometimes called a "social admission."
