This research paper is a realist review on the effectiveness of medical care for older people in the geriatric day hospital (GDH), based on trial data from a Cochrane review published in 2008. The Cochrane review indicated no overall difference between GDH care and alternative services. However, health care management and policy interventions are quite complex and methodologically more diverse than clinical treatments. Hence a ‘realist review’ is a more suitable explanatory analysis, aimed at discerning what works for whom, in what circumstances, in what respect, and how. This realist review on GDH care provides an explanatory analysis and has aimed to identify where GDH care is and is not effective.

This study compared the changes in some bio-psychosocial variables (functional independence, nutritional risk, pain, balance and walking, grip strength, general well-being, psychiatric profile, perception of social support, leisure satisfaction, and caregivers' feeling of burden) in four categories of clients during their program at a geriatric day hospital (GDH). The study also evaluated whether or not improvements, if any, were maintained 3 months after discharge. One-hundred-and-fifty-one people, categorized by primary reason for admission, were assessed at the GDH with reliable and valid tools, at admission and at discharge. Three months after discharge, they were reassessed with the same tools. Overall, two categories of clients, stroke / neurological diseases and musculoskeletal disorders / amputations, improved the most. For the gait disorders and falls group, only the functional independence score improved, but not at a clinically significant level. Finally, clients in the cognitive function disorders / psychopathologies group improved the most on their well-being scores and caregivers' burden decreased the most. All gains were maintained up to 3 months after discharge, except for leisure satisfaction. With the exception of clients who attended the GDH because of gait disorders and falls, the improvements and maintenance achieved in each category occurred in the domains where improvement had been hoped for, because of the particular disabilities in question and because of the nature of the GDH services offered.

The status of the geriatric day hospital within the National Health Service (NHS) in the UK has changed significantly over the past fifty years. We conducted a literature review starting from the inception of the geriatric day hospital, when it was viewed as the ‘shop front for geriatric services’ and was subsequently replicated in many western health systems, to the present uncertainty surrounding the model in terms of outcomes and cost effectiveness. The article also highlights the input of the Royal College of Physicians and the British Geriatric Society to the management and development of day hospitals. The geriatric day hospital has become one of the many service models under the umbrella of intermediate care services, offering comprehensive geriatric assessment and care to older people in the community. However, with the current practices of commissioning of services and ‘payment by results’, the future of this precious health resource remains uncertain.
