OBJECTIVES: To examine nonpsychiatric hospitalizations in people with schizophrenia and to describe the epidemiological features of these admissions. METHODS: We analyzed the 2000-2004 Spanish National Hospital Discharge Registry, identified records coded for schizophrenia (295.xx), selected admissions due to non-psychiatric causes and characterized the physical diseases using the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) system and the Deyo-Charlson Index. RESULTS: From all 2000-2004 hospitalizations in subjects with schizophrenia, 21 484 records (34%) were eligible for analysis. The mean age was 53 years, 61% were men. The mean number of ICD-9-CM codes was 2.3. The main diagnoses at discharge were injury-poisoning (19%) and respiratory (15%), digestive (14%) and circulatory diseases (12%), but there were significant age and gender-related differences. Inhospital mortality was 6.9% and the mean age of death was 63 years. Circulatory, respiratory diseases and neoplasms accounted for 21%, 18% and 17% of deaths, respectively. Inhospital mortality significantly correlated with age, the Deyo-Charlson Index and some specific processes. CONCLUSIONS: Hospitalizations due to physical disease are frequent among people with schizophrenia and associated with a substantial burden and in-hospital mortality in Spain. This information may prove useful for the design and application of preventive and therapeutic programs in the early and silent phases of the most prevalent physical diseases.
