In Hospital Care and Welfare Standard

The current organization of hospital care for older patients with complex healthcare needs is of insufficient quality, safety and efficiency. Frail older patients have a higher risk for development of complications and consequently a higher length of hospital stay, a higher risk of functional decline, and higher care needs after discharge. As nearly half of the patients admitted to Dutch hospitals is over 65 years, it is highly necessary to adapt the organization of hospital care to their needs. Besides having introduced the medical specialty geriatrics, hospital management has not started to provide hospital wide healthcare tailored to frail older patients. Therefore, the purpose of this study is to develop and examine the effectiveness of an intervention program for frail older patients admitted to hospital aimed at preventing functional decline and other hospital related negative outcomes.

The long-term objective of this study is to examine the effectiveness and efficiency of an intervention program for frail older patients admitted to hospital. The specific aims are:

* To develop a model of integrated hospital care, according to the principle of the Chronic Care Model, focusing both on optimizing care and wellbeing. Feasibility of such a model of care was first evaluated in a pilot study.
* To conduct a before-after study to evaluate the outcomes associated with the proposed model of hospital care in frail older inpatients. Information on outcome indicators, including autonomy, quality of life, physical and cognitive functioning, and service utilization will be collected and compared before and after implementation of the proposed model of hospital care.

We expect that older patients who participate in the intervention program after one year of implementation, compared to patients who were admitted to hospital before implementation of the intervention program, will:

* have less functional decline during admission and after three months follow-up compared to two weeks before admission;
* have a lower incidence, severity and duration of delirium during admission;
* have less cognitive decline during admission;
* are more likely to be discharged directly to their own homes;
* have less weight loss between admission and discharge;
* experience less falls during admission;
* experience less readmissions within one month after discharge;
* have a shorter length of stay;
* have a significant different pattern of use of health care services after three months follow-up;
* experience more autonomy during hospital admission and better quality of life after three months follow-up.

Additionally, we expect that the knowledge and attitudes toward care for older patients among nurses and physicians will change positively during implementation of the intervention program.
