Modernizing mental health services for older people: a case study

Area of Science:

• Geriatric Mental Health Services
• Healthcare Program Evaluation
• Complex Intervention Methodology

Background:

• Evaluation of a UK Department of Health-stimulated redevelopment program for an inner-city mental health service for older people.
• The Improving Quality of Care for Older People in Lambeth (IQCOL) program aimed to modernize services, enhance access, embed new functions, and align with community needs.
• The evaluation sought to advance knowledge in service planning and the methodology for assessing complex interventions.

Purpose of the Study:

• To evaluate the progress and outcomes of a multifaceted mental health service redevelopment program.
• To assess the achievement of program objectives, including improved access and community responsiveness.
• To contribute methodological insights into evaluating complex service changes.

Main Methods:

• A realist evaluation approach was employed, focusing on both utility and generalizability.
• A pragmatic, longitudinal design utilized iterative qualitative and quantitative methods.
• Methods were chosen to explain the change process and measure objective achievement.

Main Results:

• High participation in evaluation activities was achieved, with general workforce acceptance.
• Improved access was evidenced by a 13% increase in referrals, with earlier dementia case referrals suggested.
• Challenges included understaffing and resistance to change in one team, while localized provision requires adequate resources and support; carer support was implemented, but outreach faced boundary issues.

Conclusions:

• Successful whole-system change in services requires prioritizing the needs of implementing staff.
• Context is critical for generating generalizable evidence in service development.
• The study offers valuable methodological insights for evaluating complex healthcare interventions.
