title: Complexity of care and mental illness in medical inpatients.
abstract: We investigated the complexity of medical inpatient care to learn it was associated with the presence and type of mental disorders, and with emotional distress and somatization. Six indicators of care complexity, including length of stay (LOS), were assessed for 294 consecutive medical inpatients. Patients rated their own health and physical disability, and medical consultants assessed them for chronic and life-threatening diseases. A subsample of 157 patients was assessed for ICD-10 psychiatric diagnoses by means of an extensive semi-structured interview known as Schedules for Clinical Assessment in Neuropsychiatry (SCAN). With a few exceptions, the indicators of complexity of care were not statistically significantly associated to ICD-10 mental disorders; psychological distress, measured by the SCL-8 rating scale; or somatization, measured by the Whiteley-7 rating scale. On the other hand, four of six complexity indicators were significantly associated with self-rated physical disability or health, or both, when controlling for the severity of the medical condition. In conclusion, complexity of care, including LOS, was substantially associated with the patient's own health perception but only marginally with the presence of mental illness. This is noteworthy, as previously published results concerning the same patients have shown a clear association of mental illness with utilization of admissions to nonpsychiatric departments, and with utilization of primary care resources.
