A Tripartite Biopsychosocial Intervention Program Enhances Mental Health and Quality of Life in Elderly Patients With Depression Secondary to Geriatric Diseases

The control group received standard psychiatric care, which involved physician-led management following clinical guidelines for geriatric disease treatment, including routine medication prescriptions based on diagnostic results. At diagnosis, healthcare providers informed caregivers about the confirmed disease entity, clinical status, and necessary precautionary measures. Monthly mental health lectures were conducted for all patients, covering topics such as common psychological symptoms and coping strategies. Post-discharge, monthly outpatient follow-ups included blood pressure and glucose monitoring. Medication dosages were adjusted if patients reported changes in somatic symptoms.

The intervention group received a structured biopsychosocial program delivered by a multidisciplinary team. Geriatricians adjusted medications biweekly; rehabilitation therapists led Baduanjin sessions and monitored daily exercises via smart wristbands. Nurses provided CBT-I manuals, and psychologists offered weekly video support. Psychological care included biweekly mindfulness sessions and daily app-guided exercises, with monthly life review activities. Social support involved community events, volunteer roles, and weekly caregiver workshops. Adherence (≥70%) was tracked via app; non-compliance triggered reminders and tailored support. Exercise intensity was regulated by heart rate; patients with ≥5-point HAMD-17 increases were referred. Monthly reviews ensured ongoing quality improvement.
