The first part of this study aims to identify the occurence of depression in the elderly. In the second part, older patients with depression will be invited to a collaborative care with his or her family physician and a psychiatrist specialized in psychiatry in the elderly in accordance with a study protocol. The intervention includes two sessions where the patient will meet the psychiatrist together with the family physician, and between the two sessions the patient will have three treatment sessions with the family physician based on the evaluation by the psychiatrist. Following the last session with the psychiatrist the intervention ends with three more treatment sessions with the family physician.
The frequency of depression in the elderly is little known and experiences from family practice indicate that older people not always communicate their mental health issues or present physical complaints which may arise from a state of depression. In this study we aim to register the occurence of depression among all patients at the age of 65 or older who visit their family physician. During a period of four weeks, all patients meeting the eligibility criteria will be asked to answer a questionnaire about mental and physic health issues. Those who respond in a manner that gives reasons to believe there is a depression will be contacted by their family physician to meet for a consultation and examination. If this examination confirms the diagnosis the patient will either be treated as usual by their family physician (control group) or be invited to a collaborative care with the family physician in cooperation with a psychiatrist who is specialized in psychiatry in the elderly (intervention group). In the control group the patients will receive usual care at their family physician or be referred to a psychiatrist or a psychologist if appropriate. In the intervention group the patients will have a evaluation session with the family physician and the psychiatrist together. Following this session, the patient and the family physician will meet for three treatment consultations based on the evaluation and recommendations given by the psychiatrist. Then there will be one more joint session with the patient, the family physician and the psychiatrist and the whole treatment program ends with three more treatment consultations at the family physician. - The aim of this intervention is to examine whether this treatment program is more or equally efficient to treat depression in the elderly as usual care and at lower cost and use of specialized care.
