Analysis of diagnostic procedure costs for cerebrovascular disease admission to a highly specialized hospital.

Length of stay and hospital costs for cerebrovascular disease admissions depend on several hospital-, patient- and disease-related factors. To determine the incidence of each of these factors we studied 240 admissions for cerebrovascular diseases in a neurology division and in two medical divisions of a highly specialized hospital. Statistical analysis of the data collected from the case records revealed the effect of several factors. Some increased only the length of stay (severe neurological sequels on discharge; stay in general medicine, diagnosis of hemorrhage, arterial hypertension). Others increased investigation costs (length of stay, marital status), and costs were higher in a specialists ward. Length of stay was shorter where the nurse/bed ratio was higher. Old age and male sex were associated with a lower cost of diagnostic procedures.
