Abstract
BACKGROUND: Depression is assumed to be common in chronically ill patients during their last phase of life and is associated with poorer outcomes. The prevalence of depression is widely varying in previous studies due to the use of different terminology, classification, and assessment methods. AIM: To explore the reported incidence of depressive disorder, as registered in the last phase of life of patients who died from cardiovascular disease, cancer or COPD, in a sample of primary care patients. DESIGN AND SETTING: A historic cohort study, using a 20-year period registration database of medical records in four Dutch general practices (a dynamic population based on the Continuous Morbidity Registration database). METHOD: Medical history of the sample cohort was analysed for the diagnosis of a new episode of depressive disorder and descriptive statistics were used. RESULTS: In total 982 patients were included, and 19 patients (1.9%) were diagnosed with a new depressive disorder in the last year of their life. The lifetime prevalence of depressive disorder in this sample was 8.2%. CONCLUSION: The incidence of depressive disorder in the last phase of life is remarkably low in this study. These data were derived from actual patient care in general practice. Psychiatric diagnoses were made by GPs in the context of both patient needs and delivered care. A broader concept of depression in general practice is recommended to improve the diagnosis and treatment of mood disorders in patients in the last phase of life.
