Background: The influence of tube feeding on survival in hospitalized patients with advanced dementia is controversial., Objective: To assess long-term survival in an inception cohort, incident tube feeding placement during the index hospitalization, and the influence of tube feeding on survival in this group of patients., Subjects and Methods: Ninety-nine hospitalized patients with advanced dementia and an available surrogate decision maker were followed up through and after the index hospitalization for mortality and placement of a feeding tube. Other variables measured included advance directive status, presence of a long-term primary care physician, level of involvement of the surrogate decision maker, admitting diagnosis, prior hospitalizations, comorbidities, and diagnosis related group diagnostic category., Results: A new feeding tube was placed in 50% (51/99) of the study patients during the index hospitalization, 31% (31/99) left the hospital without a feeding tube, and 17% (17/99) were admitted with a feeding tube already in place. By stepwise logistic regression analysis, predictors of new feeding tube placement included African American ethnicity (odds ratio, 9.43; 95% confidence interval, 2.1-43.2) and residence in a nursing home (odds ratio, 4.9; 95% confidence interval, 1.02-2.5). Median survival of the 99 patients was 175 days. Eighty-five (85%) survived the index hospitalization, and 28 (28%) were still alive at last follow-up, a range of 1.3 to 4.2 years after enrollment in the study. Tube feeding was not associated with survival (P =.90). An admitting diagnosis of infection was associated with higher mortality (odds ratio, 1.9; 95% confidence interval, 1.01-3.6)., Conclusions: In this cohort of hospitalized patients with advanced dementia, risk of receiving a new feeding tube is high, associated with African American ethnicity, and prior residence in a nursing home, and has no measurable influence on survival. With or without a feeding tube, these patients have a 50% six-month median mortality.

Objectives: To ascertain the most common causes of delirium, to establish the initiation and timing of delirium, and to determine the duration of delirium in patients with hip fracture., Methods: Five hundred seventy-one (88%) of 650 patients with hip fracture admitted to 4 New York City hospitals were prospectively interviewed on a daily basis, 5 days a week, with the Confusion Assessment Method for the presence of delirium. The patients were enrolled within 48 hours of admission. Their medical charts and the data collected by the study staff were reviewed and summarized. Two of us (R.S.M. and A.L.S.) reviewed the case summaries independently and assigned a cause based on a previously developed classification system, estimated the onset of the delirious episode, and determined whether the delirium had cleared, improved, or persisted at discharge. Subsequently, discrepancies in cause, timing of initiation, and mental status on discharge between the 2 physicians reviewers were discussed until consensus was reached., Results: The prevalence of delirium was 9.5% (54/ 571; 95% confidence interval, 7.0-11.9). Seven percent of episodes were assigned a definite cause, 20% a probable cause, 11% a possible cause, and 61% were attributable to 1 or more comorbid conditions. Twenty-eight (53%) of 54 subjects developed delirium after surgery. The delirium had cleared or improved in 40 (74%) of 54 subjects at the time of discharge., Conclusions: Delirium in patients with hip fracture appears to be a different syndrome from that observed in patients who are otherwise medically ill; it also appears to follow a different clinical course. These results have important implications for the management of delirium in patients with hip fracture.

Background: Advance directives have not been uniformly used by different segments of the US population and studies have consistently shown a lower prevalence of advance directives among African Americans and Hispanics compared with non-Hispanic whites., Objective: To examine barriers to completion of health care proxies for different ethnic groups., Methods: One hundred ninety-seven subjects aged 65 years or older self-identified as African American (n = 65), Hispanic (n = 65), or non-Hispanic white (n = 67) attending a geriatrics and internal medicine outpatient clinic of a large New York City teaching hospital were administered a questionnaire. Questionnaires were developed to examine potential barriers to completion of health care proxies. Barriers were drawn from the literature and from focus groups., Results: Significant predictors of proxy completion using logistic regression analysis included knowledge of health care proxies, availability of a health care agent, exposure to mechanical ventilation, age, and self-reported health status as fair to poor. Subjects who believed that a health care agent was irrelevant in the setting of involved family were significantly less likely to have completed a health care proxy. Although there were significant differences in the baseline completion rates of health care proxies for the 3 ethnic groups, ethnicity did not predict prior appointment of a health care agent in multivariate analysis., Conclusions: Differences in health care proxy completion rates across white, African American, and Hispanic elderly individuals in this New York City population seem to be related to potentially reversible barriers such as lack of knowledge and the perceived irrelevance of advance directives in the setting of involved family. Enhanced educational efforts of both health care personnel and patients could increase the rate of formal health care proxy appointment.

Background: Most Americans die in the acute care hospital, where aggressive, life-prolonging interventions are readily performed. Although patients with incurable illness might prefer palliative care, perceived differences in prognosis by physicians may influence the type of care provided. Patients with advanced cancer and advanced dementia represent 2 extremes in the use of hospice services and may also be treated differently in the acute care hospital. We tested this hypothesis and quantitated the use of nonpalliative interventions in hospitalized, incurably ill patients., Methods: Charts of elderly patients with advanced dementia or metastatic solid tumor malignancy who died during a 13-month period in a tertiary care acute teaching hospital were reviewed. Main outcome measures included the number of patients receiving invasive of noninvasive (but complex) diagnostic tests, invasive nonpalliative treatments, cardiopulmonary resuscitation, systemic antibiotics, and do-not-resuscitate orders., Results: Charts of 164 patients (80 with dementia and 84 with cancer) were reviewed. Overall, 47% received invasive nonpalliative treatments. Controlling for age, sex, length of stay, and insurance status, the groups were equally likely to receive nonpalliative treatments (P = .75), but patients with dementia were more likely to receive new feeding tubes (P = .02). Cardiopulmonary resuscitation was attempted for 24% of each group. Patients with cancer more often received invasive (41% vs 13%; P = .002) and complex noninvasive diagnostic tests (49% vs 23%; P = .02). Overall, 88% received antibiotics, often empirically, but, controlling for neutropenia and invasive tests and treatments, patients with dementia were significantly more likely to receive antibiotics for an identifiable infection (P = .004)., Conclusions: Incurably ill patients often receive nonpalliative interventions at the end of life. Patients with cancer receive more diagnostic tests, but patients with dementia receive more enteral tube feeding. Patients commonly receive systemic antibiotics, often empirically. Cardiopulmonary resuscitation is equally applied, but is out of proportion to expected survival.

Background: Advance directives provide a means for patients to retain influence on their medical care should decisional capacity be lost. Several studies have now demonstrated that advance directives that are completed in the ambulatory care setting are rarely available and recognized when patients are admitted to the acute care hospital., Objective: To evaluate a generalizable model for improving recognition of previously completed advance directives and for promoting appointment of health care proxies in hospitalized patients., Methods: Hospitalized elderly patients were randomly assigned to receive the intervention or usual care (n = 190). Intervention patients with capacity were counseled by hospital patient representatives about advance directives and encouraged to complete health care proxies. Patients with existing proxies had this information noted in their charts. For patients without capacity, counselors reviewed their charts for proxy documentation and if absent, contacted patients' next of kin and private physicians to determine proxy status. Usual care patients were not contacted by patient representatives., Results: Forty-eight percent of intervention patients completed a new proxy or had a previously completed proxy identified compared with 6% of controls (P < .001). For patients with capacity, 22% of intervention patients had a previously appointed proxy agent identified compared with 6% of controls (P < .001). Thirty-six percent of intervention patients appointed a proxy decision maker compared with 0% of controls (P < .02). For patients without capacity, 31% of intervention patients had previously appointed proxies identified compared with 6% of controls (P < .001)., Conclusions: Counseling by hospital patient representatives is an effective and generalizable means of improving recognition and execution of advance directives in the acute care hospital.
