Heart Failure, Functional and Cognitive Decline, and Psychiatric Symptoms in Nursing Home Patients
The Effect of Congestive Heart Failure on Functional and Cognitive Decline and Neuropsychiatric Symptoms in Residents of Long-term Care Facilities

Detailed Description
The prevalence of Heart Failure (HF) is rising, primarily among the elderly. HF has been diagnosed in 15 and 30% of elderly residents of long-term care facilities (LTCF). HF is associated with a high mortality rate and is the most common reason elderly persons are hospitalized. The economic impact of HF is substantial. Despite advances in the management of HF, the elderly are less likely to receive recommended therapies. This may reflect under-representation of the frail elderly in clinical trials of HF treatment. The elderly are more likely to experience adverse effects. In addition, HF trials have focused on mortality and hospitalization as outcome measures, which may be less relevant to the frail elderly who may be more concerned about preventing disability and preserving cognition.
Recent studies have demonstrated an association between functional decline, cognitive impairment and HF. Functional decline is defined as a loss in the ability to independently perform basic activities of self-care. In addition, patients with HF may be more likely to suffer from behavioural and psychological difficulties those without HF. The primary hypothesis of this study is that elderly residents of LTCF with a history of HF experience a more rapid rate of functional decline than residents without such a history. The secondary hypotheses are that elderly residents of LTCF with HF also experience a more rapid rate of cognitive decline and a greater burden of associated behavioural and psychological symptoms.
We propose to conduct a prospective cohort study in 25 LTCF in Hamilton, 9 LTCF in Kitchener-Waterloo, and 7 LTCF in Cambridge, all in Ontario. All newly admitted residents to these facilities will be considered for inclusion. Residents for whom consent cannot be obtained or who are not expected to survive more than eight weeks due to an underlying malignancy, end-stage neurological illness or other palliative diagnosis will be excluded. Approximately 600 patients will be recruited, 20% of which are expected to have a history of HF.
Residents for whom consent is obtained will be assessed by a research nurse. The assessment consists of a standardized history and physical examination, review of pertinent medical records, and an assessment of function (Barthel Index), cognition (MDS-COGS), and neuropsychiatric symptoms (Cohen-Mansfield Agitation Inventory and Neuropsychiatric Inventory). These measurements will be obtained at baseline and every three months thereafter for up to a year. The diagnosis of HF will be confirmed by two specialists using standard criteria. Residents with a history of HF will be compared to those without this history. Mortality, emergency room visits, acute hospitalizations, and falls will be measured.
Thus far, no studies have prospectively examined functional and cognitive decline in LTCF residents with HF. No studies have examined the relationship between HF and psychological and behavioural symptoms in these patients. As elderly residents of LTCF represent the frailest of the frail elderly, the results of this study are likely to be generalizable to the frail elderly in the community. We hope to apply the results of this study to future research aiming to determine whether treatment of HF can be optimized to reduce functional and cognitive decline in LTCF residents with HF, in order to preserve their independence and current level of disability as long as possible.
