Length of stay and antipsychotic treatment costs of patients with acute psychosis admitted to hospital in Spain. Description and associated factors. The Psychosp study.
OBJECTIVE
The aim of this study was to describe the length of stay, cost of drug treatment, diagnostic tests and other therapeutic measures in acute psychotic patients admitted to acute in-patient psychiatric units and to analyse the factors associated with these.


METHODS
A retrospective review was made of medical records of 200 patients admitted for acute psychosis in eight Spanish hospitals. Information was collected concerning the length of stay, cost of drug treatment and diagnostic tests; bivariate and multivariate analysis was made of factors associated with length of stay and cost of antipsychotic drug treatment.


RESULTS
The average admission cost ranged between 2,830.29 and 3,624.95 euros, with a wide variability among hospitals. Of this cost, 94.3% corresponded to fixed costs, 3.4% to diagnostic tests and 2.4% to drug treatment (84.2% of this latter cost corresponded to antipsychotic drugs). Age younger than 25 years and a diagnosis of schizophrenia were associated with longer hospital stays; longer length of stay, the presence of aggressiveness/agitation, a diagnosis of schizophrenia, age younger than 25 years and the use of atypical antipsychotics were associated with higher costs in antipsychotic drug treatment.


CONCLUSIONS
The hospital admission cost of an acute psychotic episode is mostly dependent on the structural costs derived from in-patient treatment. The differences in costs seem to be related to the different length of stay schemes used by the various hospitals rather than to the clinical characteristics of patients or the drugs used.
