Characteristics of patients requesting and receiving physician-assisted death.

BACKGROUND: Surveys have shown that physicians in the United States report both receiving and honoring requests for physician assistance with a hastened death. The characteristics of patients requesting and receiving physician aid in dying are important to the development of public policy. OBJECTIVE: To determine patient characteristics associated with acts of physician-assisted suicide. DESIGN: Physicians among specialties involved in care of the seriously ill and responding to a national representative prevalence survey on physician-assisted suicide and euthanasia were asked to describe the demographic and illness characteristics of the most recent patient whose request for assisted dying they refused as well as the most recent request honored. RESULTS: Of 1902 respondents (63% of those surveyed), 379 described 415 instances of their most recent request refused and 80 instances of the most recent request honored. Patients requesting assistance were seriously ill, near death, and had a significant burden of pain and physical discomfort. Nearly half were described as depressed at the time of the request. The majority made the request themselves, along with family. In multivariate analysis, physicians were more likely to honor requests from patients making a specific request who were in severe pain (odds ratio, 2.4; 95% confidence interval, 1.01-5.7) or discomfort (odds ratio, 6.5; 95% confidence interval, 2.6-16.1), had a life expectancy of less than 1 month (odds ratio, 4.3; 95% confidence interval, 1.7-10.8), and were not believed to be depressed at the time of the request (odds ratio, 0.2; 95% confidence interval, 0.1-0.5). CONCLUSION: Persons requesting and receiving assistance in dying are seriously ill with little time to live and a high burden of physical suffering.

Cognitive impairment in hip fracture patients: timing of detection and longitudinal follow-up.

OBJECTIVES: To examine the prevalence, incidence, persistence, predictors, and outcomes of cognitive impairment after hip fracture. DESIGN: Longitudinal cohort study. SETTING: Eight hospitals in Baltimore, Maryland. PARTICIPANTS: Six hundred seventy-four hip fracture patients aged 65 and older living in the community before fracture. MEASUREMENT: Delirium at admission and postsurgery, Mini-Mental State Examination (MMSE) scores postsurgery, and prefracture proxy ratings of MMSE and dementia. Follow-up measures at 2 and 12 months postfracture included mortality, MMSE, physical activities of daily living (PADLs), instrumental activities of daily living (IADLs), social functioning, and the Center for Epidemiologic Studies-Depression Scale. RESULTS: Overall, 28% had prefracture dementia or MMSE impairment, 8% had cognitive impairment first detected presurgery, 14% had impairment first detected postsurgery, and 50% were not impaired before or during hospitalization. Incident cognitive impairment was more likely in patients who were older, male, and less educated and had more prefracture PADL impairment, intertrochanteric fractures, and higher anesthesia risk ratings. Presurgery incident cases did not differ significantly from those detected postsurgery in functional outcomes or in persistence of cognitive impairment. Cognitive impairment first noted in the hospital persisted through 2 and 12 months in more than 40% of patients. Those with cognitive impairment persisting through 2 months had poorer 12-month PADLs and social functioning. CONCLUSION: Prefracture cognitive impairment and incident cognitive impairment during hospitalization are risk factors for poor functional outcomes. Many incident cognitive problems persisted over 2 to 12 months, and per-sistence predicted later functional and social impairment.

Relationship between pain and opioid analgesics on the development of delirium following hip fracture.

BACKGROUND: Delirium and pain are common following hip fracture. Untreated pain has been shown to increase the risk of delirium in older adults undergoing elective surgery. This study was performed to examine the relationship among pain, analgesics, and other factors on delirium in hip fracture patients. METHODS: We conducted a prospective cohort study at four New York hospitals that enrolled 541 patients with hip fracture and without delirium. Delirium was identified prospectively by patient interview supplemented by medical record review. Multiple logistic regression was used to identify risk factors. RESULTS: Eighty-seven of 541 patients (16%) became delirious. Among all subjects, risk factors for delirium were cognitive impairment (relative risk, or RR, 3.6; 95% confidence interval, or CI, 1.8-7.2), abnormal blood pressure (RR 2.3, 95% CI 1.2-4.7), and heart failure (RR 2.9, 95% CI 1.6-5.3). Patients who received less than 10 mg of parenteral morphine sulfate equivalents per day were more likely to develop delirium than patients who received more analgesia (RR 5.4, 95% CI 2.4-12.3). Patients who received meperidine were at increased risk of developing delirium as compared with patients who received other opioid analgesics (RR 2.4, 95% CI 1.3-4.5). In cognitively intact patients, severe pain significantly increased the risk of delirium (RR 9.0, 95% CI 1.8-45.2). CONCLUSIONS: Using admission data, clinicians can identify patients at high risk for delirium following hip fracture. Avoiding opioids or using very low doses of opioids increased the risk of delirium. Cognitively intact patients with undertreated pain were nine times more likely to develop delirium than patients whose pain was adequately treated. Undertreated pain and inadequate analgesia appear to be risk factors for delirium in frail older adults.

Assessing differences in care needs and service utilization in geriatric palliative care patients.

Little is known of the palliative care needs and experiences of older adults. This study explored whether these needs differed from those of younger patients. We performed a retrospective data analysis of 1184 palliative care consultations in a major teaching hospital. There were statistically significant differences across age groups in patient demographic and clinical characteristics, advance care planning, and service utilization. Patients over age 80 had a reduced prevalence of cancer, a higher prevalence of dementia and incapacity, more frequent decisions to withhold or withdraw life-sustaining treatments, and fewer interventions for symptom management. The palliative care needs of older adults appear to be substantially different from those of younger patients. Dementia and incapacity profoundly influence decision-making, requiring more time and communication with patients and families.

The effect of do-not-resuscitate orders on physician decision-making.

The effect of do-not-resuscitate (DNR) orders on physicians' decisions to provide life-prolonging treatments other than cardiopulmonary resuscitation (CPR) for patients near the end of life was explored using a cross-sectional mailed survey. Each survey presented three patient scenarios followed by 10 treatment decisions. Participants were residents and attending physicians who were randomly assigned surveys in which all patient scenarios included or did not include a DNR order. Response to three case scenarios when a DNR order was present or absent were measured. Response from 241 of 463 physicians (52%) was received. Physicians agreed or strongly agreed to initiate fewer interventions when a DNR order was present versus absent (4.2 vs 5.0 (P =.008) in the first scenario; 6.5 vs 7.1 (P =.004) in the second scenario; and 5.7 vs 6.2 (P =.037) in the third scenario). In all three scenarios, patients with DNR orders were significantly less likely to be transferred to an intensive care unit, to be intubated, or to receive CPR. In some scenarios, the presence of a DNR order was associated with a decreased willingness to draw blood cultures (91% vs 98%, P =.038), central line placement (68% vs 80%, P =.030), or blood transfusion (75% vs 87%, P =.015). The presence of a DNR order may affect physicians' willingness to order a variety of treatments not related to CPR. Patients with DNR orders may choose to forgo other life-prolonging treatments, but physicians should elicit additional information about patients' treatment goals to inform these decisions.

Assessing the outcome of a palliative care educational initiative.

PURPOSE: In 1997, a biweekly, 18-month Palliative Care Seminar Series was started at Mount Sinai School of Medicine as a way to explore participants' beliefs about palliative care and to instill the knowledge, skills, and attitudes needed to improve care at the end of life. The goal of this study was to examine the effects of Mount Sinai's Palliative Care Seminar Series on faculty development and personal growth. METHODS: Twenty of 42 respondents were interviewed immediately after completing the Seminar Series. Subjects identified themselves as physicians (n = 16) or nurses (n = 4). The same open-ended questions and follow-up probes were asked of each interviewee and transcripts were coded for confidentiality. The questions were developed to examine the impact of the Seminar Series on practitioners' knowledge of and attitude toward end-of-life care. Content analysis of the coded transcripts was performed by a group consisting of one physician, one medical student, and two social scientists. RESULTS: Content analysis of interview transcripts revealed five common themes: subjects perceived a gain in palliative care knowledge and skills; they believed themselves to be more confident in the practice of palliative care; they believed themselves to be more confident that what they were doing is appropriate; and they felt less isolated in their beliefs as a result of regular interactions with supportive peers. CONCLUSIONS: Five common themes arose from the transcripts of both physicians and nurses: participants perceived a gain in palliative care "practice" skills, participants perceived a gain in palliative care "process" skills, participants believed themselves to be more confident that palliative care was appropriate care for dying patients, participants believed themselves to be more confident in their ability to practice and teach palliative care, and participants felt less isolated in their beliefs through regular interactions with supportive peers.
