Abstract
Calcific aortic stenosis can be considered a model for geriatric cardiovascular conditions due to a confluence of factors. The remarkable technological development of transcatheter aortic valve replacement was studied initially on older adult populations with prohibitive or high-risk for surgical valve replacement. Through these trials, the cardiovascular community has recognized that stratification of these chronologically older adults can be improved incrementally by invoking the concept of frailty and other geriatric risks. Given the complexity of the aging process, stratification by chronological age should only be the initial step but is no longer sufficient to optimally quantify cardiovascular and noncardiovascular risk. In this review, we employ a geriatric cardiology lens to focus on the diagnosis and the comprehensive management of aortic stenosis in older adults to enhance shared decision-making with patients and their families and optimize patient-centered outcomes. Finally, we highlight knowledge gaps that are critical for future areas of study.

Abstract
Atrial fibrillation is the most common sustained cardiac arrhythmia. The scope and impact of atrial fibrillation are wide; it can affect cardiac function, functional status, and quality of life, and it confers a stroke risk. There are sex differences in atrial fibrillation across the scope of the disease process, from epidemiology and causative mechanisms to management and outcomes. The approach to management of atrial fibrillation differs between women and men, and there are sex differences in response to medical therapy and catheter ablation. There are many gaps in our knowledge of the gender differences in atrial fibrillation, and many opportunities for future research.

Abstract
Abstract
Background: WISDOM is a 100,000 healthy women preference-tolerant, pragmatic study comparing annual to personalized risk-based breast screening. The novelty of WISDOM personalized screening is the integration of previously validated genetic and clinical risk factors (age, family history, breast biopsy results, ethnicity, mammographic density) into a single risk assessment model that directs the starting age, timing, and frequency of screening. The goal of WISDOM is to determine if personalized screening, compared to annual screening, is as safe, less morbid, enables prevention, and is preferred by women. The study is registered on ClinicalTrials.gov, NCT02620852.
Methods: Women aged 40-74 years with no history of breast cancer or DCIS, and no previous double mastectomy can join the study online at wisdomstudy.org. Participants can elect randomization or self-select a study arm, and provide electronic consent and Release for Medical Information using DocuSign. For all participants, 5-year risk of developing breast cancer is calculated according to the Breast Cancer Screening Consortium (BCSC) model. Participants in the personalized arm undergo panel-based mutation testing, and their 5-year risk is calculated using the BCSC score combined with a Polygenic Risk Score (BCSC-PRS) that includes 75 single nucleotide polymorphisms (SNPs, increase to 229) known to increase breast cancer risk. SNPs and mutations (BRCA1, BRCA2, TP53, PTEN, STK11, CDH1, ATM, PALB2, and CHEK2) are assessed by saliva-based testing through Color Genomics. 5-year risk level thresholds are used to stratify for low-, moderate- and high risk. Risk stratification determines age to start, stop, and frequency of screening.
Enrollment: As of July 2018, the WISDOM study is open to all eligible women in California, North Dakota, South Dakota, Minnesota and Iowa. To date, 23,329 eligible women have registered and 14,393 women have consented to participate in the trial. We analyzed 3,255 participants who have completed risk assessment in the personalized arm. The median age was 56 years. 82% were Caucasian, 1% African-American, and 6% Asian. 9% self-reported as Hispanic. We are partnering with health insurers and self-insured companies using coverage with evidence progression. To strengthen generalizability, we are expanding to other states. WISDOM enrollment will continue past 2019.
Feasibility: To evaluate the addition of PRS, we used paired statistical tests (McNemar) to compare the distributions of BCSC, and BCSC-PRS risk estimates around low-risk (<1.3%), and very-high risk (>6%) thresholds, the latter corresponding to 5-year risk of a BRCA mutation carrier. The median 5-year risk was 1.5% (IQR 1.0-2.1%) using the BCSC model, and 1.4% (IQR 0.8-2.5%) using the BCSC-PRS model. The BCSC-PRS model classified more women into the low (<1%) and very high (≥6%) risk categories compared to the BCSC model (p < 0.001).
Conclusions: Our findings demonstrate that incorporating genetic variants into a validated clinical model is feasible and impacts risk classification compared to a model without genetic risk factors. Results at 5 years will reveal if this classification improves healthcare value by reducing screen volumes and costs without jeopardizing outcomes.

Abstract
Abstract
Introduction: The purpose of this study is to examine whether participation in a personalized screening trial is associated with anxiety or breast cancer worry. The Patient Centered Outcomes Research Institute recently funded WISDOM (Women Informed to Screen Depending On Measures of risk), which is a randomized trial that tests the safety and efficacy of basing starting age, stopping age, frequency and modality of breast cancer screening on individual risk (Clinical Trials Identifier NCT02620852).
Methods: In WISDOM, participants can be randomized to annual screening or personalized screening arm, or self-select an arm an observational cohort. This interim analysis examined the first 1817 participants to determine if the personalized risk arm is acceptable and to explore whether baseline anxiety was associated with study arm. For acceptability our target was to have >60% of participants agree to randomization. Participants completed questions about their Risk Perception, the PROMIS Anxiety short form 8a (total scores 8-40 with higher scores indicating more anxiety), and Breast Cancer Risk Worry (BCRW) survey (total scores 5-20) with higher scores indicating more worry) at baseline and before they were given information on their personal risk or study assignment. For the purposes of these analyses, we defined high anxiety to be the percentage of participants scoring =>22 on the PROMIS and >8 on the BCRW.
Results: The participants were recruited from three sites (UCSD, UCSF, Sanford Health). Of the 1817 initial participants, 1643 completed the baseline questionnaire. Participants has a mean age of 57 years (SD 9). 15.8% felt their chances of developing breast cancer was high, 19.5% felt their chance of developing breast cancer was greater than the average women, and 56.6% felt their lifetime risk of developing breast cancer was >25. Risk perception was not significantly different between women who opted to be randomized versus the observational arm.
The majority of participants were willing to be randomly assigned to an arm (1071/1643, 65.1%). Of those who joined the observational cohort, the majority selected personalized risk arm (474/572, 82.9%). Overall, PROMIS anxiety scores were low at baseline (14.0 MEAN (SD 4.6)) as were the Breast Cancer Risk Worry scores (5.7 MEAN (SD 1.05)). Less than 8% of participants had PROMIS scores >22 and that did not vary across the randomized or observational groups (P=0.2)). About 2% of participants had a BCRW scores >8. Women who worried with breast cancer were more likely to select to be in the observational (3.5%) than randomized (1.7%) arm of the study (P=0.02).
Conclusions: For the women approached to participate in Wisdom, personalized screening was acceptable alternative to annual mammography. Participants in general overestimated their lifetime risk of breast cancer, had very low anxiety and low breast cancer worry. Those who were worried about breast cancer opted more often for the observational arm of the study to allow them to choose between the personalized versus annual arm. Future analyses will follow participants prospectively to determine adherence to assigned or selected arm, and whether anxiety changes after receipt of their personalized risk information.

Abstract
BACKGROUND Intensive dietary intervention programs may lead to benefits in vitality and other components of health quality. The Women's Health Initiative Dietary Modification (DM) intervention includes a large randomized controlled trial of an intensive intervention. OBJECTIVE To evaluate whether the intervention is associated with improved health-related quality of life (HRQoL) subscales, overall self-reported health, depression symptoms, cognitive functioning, and sleep quality. DESIGN This randomized controlled trial was analyzed as intent to treat. PARTICIPANTS Between 1993 and 1998, 48,835 women aged 50 to 79 years were recruited by 40 clinical centers across the United States. Eligibility included having fat intake at baseline ≥32% of total calories, and excluded women with any prior colorectal or breast cancer, recent other cancers, type 1 diabetes, or medical conditions with predicted survival <3 years. INTERVENTION Goals were to reduce calories from fat to 20%, increase vegetables and fruit to 5+ servings, and increase grain servings to 6+ servings a day. During the first year, 18 group sessions were held, with quarterly sessions thereafter. MAIN OUTCOME MEASURES The RAND 36-Item Health Survey was used to assess HRQoL at baseline, Year 1, and close-out (about 8 years postrandomization), and estimate differential HRQoL subscale change scores. STATISTICAL ANALYSES PERFORMED Mean change in HRQoL scores (Year 1 minus baseline) were compared by randomization group using linear models. RESULTS At 1 year, there was a differential change between intervention and comparison group of 1.7 units (95% CI 1.5, 2.0) in general health associated with the intervention. DM intervention improved physical functioning by 2.0 units (95% CI 1.7, 2.3), vitality by 1.9 units (95% CI 1.6, 2.2), and global quality of life by 0.09 units (95% CI 0.07, 0.12). With the exception of global quality of life, these effects were significantly modified by body mass index at baseline. CONCLUSIONS DM intervention was associated with small, but significant improvements in three HRQoL subscales: general health, physical functioning, and vitality at 1 year follow-up, with the largest improvements seen in the women with the greatest baseline body mass index.

Abstract
Abstract
Background: The Athena Breast Health Network is a University of California (UC) initiative to drive rapid innovation in patient-centered prevention, screening, and treatment of breast cancer. Athena is a collaborative of the five UC medical centers and UC Berkeley that integrates clinical care and research, rapidly mobilizing data and research to enable continuous improvement in patient care and outcomes. The first initiative of Athena was to implement risk assessment for women being screened for breast cancer and to offer tailored referrals for women found to be at increased risk of developing breast cancer.
Methods: Patients who enroll in Athena complete an electronic questionnaire to collect personal and family history data prior to their mammography screening visit. These data are used to generate multiple risk assessments using the NCCN and USPSTF guidelines, and BCRAT (Gail model). Data on established breast cancer risk factors such as chest wall radiation and history of hormone replacement therapy are also collected and used to identify women at potentially increased risk. Upon enrollment, women are given the opportunity to provide a blood or saliva sample for research purposes.
Women who meet Athena-defined criteria that identify them to be at increased risk receive a referral to a Breast Health Specialist (BHS). The BHS identifies individual patient needs for prevention and screening services, including genetic counseling and testing, provides referrals to a High Risk Breast Clinic or nurse practitioner, and conducts lifestyle modification counseling. BHS have special training in breast cancer risk assessment, and some are licensed genetic counselors. Primary care and/or referring providers are directly informed of risk assessment results through mailings or the electronic medical record.
Results: The recruitment goal enrollment for Athena is 150,000 and to date more than 17,000 women have been enrolled across the five centers. Of those enrolled, 32% indicated that they have a family history of cancer. 56% of the cohort consented to participate in research, and 40% provided a biospecimen for research purposes. Across the five centers, 32 educational outreach sessions about Athena were held, reaching approximately 375 providers.
Conclusion: Successful implementation of the Athena risk assessment and decision support process will enable the identification of high risk women who are most likely to benefit from tailored screening or risk reducing interventions and who otherwise may not have been referred for risk reducing measures. By identifying women at the highest risk and connecting them to screening and prevention resources, the Athena Breast Health Network aims to ultimately reduce the incidence of breast cancer in its participant cohort.

Abstract
OBJECTIVES To evaluate care provided by primary care physicians in community practice to older patients presenting with cognitive impairment and dementia. DESIGN Secondary analysis of an intervention study. SETTING Primary care clinics. PARTICIPANTS 101 patients 75 years and older enrolled in the ACOVE-2 study who presented with a new cognitive problem, new dementia, or prevalent dementia. MEASUREMENTS Patients assessment and management were evaluated from medical record review and caregiver interviews. RESULTS Among 34 patients presenting with a new cognitive problem, half received a cognitive assessment comprising of a test of memory and one other cognitive task, 41% were screened for depression and 29% were referred to a consultant. Of the 27 patients with newly diagnosed dementia, 15% received the components of a basic neurological examination, one-fifth received basic laboratory testing and for one third the medical record reflected an attempt to classify the type of dementia. Counseling was under-reported in the medical record compared to the caregiver interview for the 101 patients with dementia, but even the interview revealed that about half or fewer patients received counseling about safety and accident prevention, caregiver support or managing conflicts. Less than 10% were referred to a social worker. CONCLUSION This small but detailed evaluation suggests patients presenting with cognitive problems to primary care physicians do not consistently receive basic diagnosis and management.

Abstract
The Treating to New Targets (TNT) clinical trial found that intensive 80 mg atorvastatin (A80) treatment reduced cardiovascular events by 22% when compared to 10 mg atorvastatin (A10) treatment. We evaluated the cost-effectiveness of intensive A80 vs A10 treatment in the United Kingdom (UK), Spain, and Germany. A lifetime Markov model was developed to predict cardiovascular disease-related events, costs, survival, and quality-adjusted life-years (QALYs). Treatment-specific event probabilities were estimated from the TNT clinical trial. Post-event survival, health-related quality of life, and country-specific medical-care costs were estimated using published sources. Intensive treatment with A80 increased both the per-patient QALYs and corresponding costs of care, when compared to the A10 treatment, in all three countries. The incremental cost per QALY gained was <euro> 9,500, <euro> 21,000, and <euro> 15,000 in the UK, Spain, and Germany, respectively. Intensive A80 treatment is estimated to be cost-effective when compared to A10 treatment in secondary cardiovascular prevention.

Abstract
BACKGROUND AND PURPOSE Raloxifene, a selective estrogen receptor modulator, reduces risk of invasive breast cancer and osteoporosis, but the effect on risk for stroke and venous thromboembolism in different patient subgroups is not established. The purpose of this analysis was to evaluate the effect of raloxifene on the incidence of all strokes, stroke deaths, and venous thromboembolic events according to participant subgroups. METHODS This was a secondary end point analysis of an international, randomized, placebo-controlled clinical trial of 10 101 postmenopausal women with or at increased risk of coronary heart disease followed a median of 5.6 years. Strokes, venous thromboembolic events, and deaths were adjudicated by expert centralized committees. Strokes were categorized as ischemic, hemorrhagic, or undetermined and venous thromboembolic events were subclassified. RESULTS The incidences of all strokes did not differ between raloxifene (incidence rate per 100 woman-years=0.95) and placebo (incidence rate=0.86) treatment groups (P=0.30). In women assigned raloxifene versus placebo, there was a higher incidence of fatal strokes (incidence rates=0.22 and 0.15, respectively, P=0.0499) and venous thromboembolic events (incidence rates=0.39 and 0.27, respectively, P=0.02). No significant subgroup interactions were found except that there was a higher incidence of stroke associated with raloxifene use among current smokers. CONCLUSIONS In postmenopausal women at increased risk for coronary events, the incidences of venous thromboembolism and fatal stroke but not all strokes were higher in those assigned raloxifene versus placebo. Raloxifene's effect did not differ across subgroups, except that the risk of stroke differed by smoking status. Treatment decisions about raloxifene should be based on a balance of projected absolute risks and benefits.

Abstract
1530 Background: RUTH enrolled 10,101 postmenopausal women at increased risk for major coronary events. Women were not enrolled based on their risk for breast cancer. The incidence of invasive breast cancer in the placebo group was low for this older population of women (mean age 67.5 years). The aim of this analysis was to determine whether CHD risk factors and selected cardiac medications were protective against invasive breast cancer in this population at increased risk for coronary events. Methods: Covariates assessed were baseline factors that are known CHD risk factors and selected medications ( Table ). Univariate analyses were performed for all covariates using placebo data. Results: The effect of baseline CHD risk factors and selected cardiac medications on the incidence of invasive breast cancer in women receiving placebo in RUTH (N=5057) Conclusions: In these postmenopausal women at increased risk for major coronary events, baseline CHD risk factors and selected cardiac medications assessed individually did not protect against invasive breast cancer. The low incidence of invasive breast cancer in the RUTH population does not appear to be due to the presence of CHD risk factors or use of cardiac medications. [Table: see text] [Table: see text]

Sex-specific effects of diabetes on adverse outcomes after percutaneous coronary intervention: trends over time. Am Heart J 2007; 153:970-8. [PMID: 17540197 DOI: 10.1016/j.ahj.2007.03.036] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2007] [Accepted: 03/15/2007] [Indexed: 01/14/2023]
Abstract
BACKGROUND Diabetes is a stronger risk factor for coronary heart disease in women than in men. Whether diabetes also poses greater risks to women after percutaneous coronary intervention (PCI) has not been examined. METHODS We examined 20586 PCI procedures at Emory University Hospitals (Atlanta, GA) between 1990 and 2003. Hazard ratios (HRs) for 1-year major adverse cardiac events were calculated comparing diabetic with nondiabetic patients by sex and study year. Data were adjusted for demographic and clinical factors using Cox proportional hazards models. RESULTS Despite increasing patient age and comorbidity burden, diabetic and nondiabetic men had a significant improvement in PCI outcomes between 1990 and 2003 (P < .001). Diabetic women also tended to have improved PCI outcomes over time (P = .073), but not nondiabetic women (P = .206). Overall, diabetes had a stronger association with adverse outcomes in women (HR 1.93, 95% CI 1.55-2.40) than in men (HR 1.26, 95% CI 1.09-1.47) (P = .002 for the interaction between sex and diabetes). The excess risk associated with diabetes in women, however, was largely driven by early study years (1990-1993). This excess risk associated with diabetes in women declined over time, and diabetes had a similar effect on outcomes in both women and men in more recent years (P = .010 for the interaction between sex, diabetes, and time). CONCLUSIONS Percutaneous coronary intervention outcomes of diabetic and nondiabetic men have improved in recent years. However, among women, diabetic patients had greater improvements in outcomes after PCI compared with nondiabetic patients. As a result, diabetes is no longer a stronger risk factor for adverse outcomes after PCI in women than in men.

Abstract
OBJECTIVES To evaluate the applicability of process-of-care quality indicators (QIs) to vulnerable elders and to measure the effect of excluding indicators based on patients' preferences and for advanced dementia and poor prognosis. DESIGN The Assessing Care of Vulnerable Elders (ACOVE) project employed 203 QIs for care of 22 conditions (including six geriatric syndromes and 11 age-associated diseases) for community-based persons aged 65 and older at increased risk of functional decline or death. Relevant QIs were excluded for persons deciding against hospitalization or surgery. A 12-member clinical committee (CC) of geriatric experts rated whether each QI should be applied in scoring quality of care for persons with advanced dementia (AdvDem) or poor prognosis (PoorProg). Using content analysis, CC ratings were formulated into a model of QI exclusion. Quality scores with and without excluded QIs were compared. SETTING Enrollees in two senior managed care plans, one in the northeast United States and the other in the southwest. PARTICIPANTS CC members evaluated applicability of QIs. QIs were applied to 372 vulnerable elders in two senior managed care plans. MEASUREMENTS Frequency and type of QIs excluded and the effect of excluding QIs on quality of care scores. RESULTS Of the 203 QIs, a patient's preference against hospitalization or surgery excluded 10 and eight QIs, respectively. The CC voted to exclude 81.5 QIs (40%) for patients with AdvDem and 70 QIs (34%) for patients with PoorProg. Content analysis of the CC votes revealed that QIs aimed at care coordination, safety or prevention of decline, or short-term clinical improvement or prevention with nonburdensome interventions were usually voted for inclusion (90% and 98% included for AdvDem and PoorProg, respectively), but QIs directed at long-term benefit or requiring interventions of moderate to heavy burden were usually excluded (16% and 19% included, respectively). About half of QIs aimed at age-associated diseases were voted for exclusion, whereas fewer than one-quarter of QIs for geriatric syndromes were excluded. Thirty-nine patients (10%) in our field trial held preferences or had clinical conditions that would have excluded 68 QIs. This accounted for 5% of all QIs triggered by these 39 patients and 0.6% of QIs overall. The quality score without exclusion was 0.57 and with exclusion was 0.58 (P =.89). CONCLUSION Caution is required in applying QIs to vulnerable elders. QIs for geriatric syndromes are more likely to be applicable to these individuals than are QIs for age-associated diseases. The objectives of care, intervention burdens, and interval before anticipated benefit affect QI applicability. At least for patients with AdvDem and PoorProg, identification of applicable or inapplicable QIs is feasible. In a community-based sample of vulnerable elders, few QIs are excluded.

Abstract
CONTEXT The Heart and Estrogen/progestin Replacement Study (HERS) found no overall reduction in risk of coronary heart disease (CHD) events among postmenopausal women with CHD. However, in the hormone group, findings did suggest a higher risk of CHD events during the first year, and a decreased risk during years 3 to 5. OBJECTIVE To determine if the risk reduction observed in the later years of HERS persisted and resulted in an overall reduced risk of CHD events with additional years of follow-up. DESIGN AND SETTING Randomized, blinded, placebo-controlled trial of 4.1 years' duration (HERS) and subsequent unblinded follow-up for 2.7 years (HERS II) conducted at outpatient and community settings at 20 US clinical centers. PARTICIPANTS A total of 2763 postmenopausal women with CHD and average age of 67 years at enrollment in HERS; 2321 women (93% of those surviving) consented to follow-up in HERS II. INTERVENTION Participants were randomly assigned to receive 0.625 mg/d of conjugated estrogens and 2.5 mg of medroxyprogesterone acetate (n = 1380), or placebo (n = 1383) during HERS; open-label hormone therapy was prescribed at personal physicians' discretion during HERS II. The proportions with at least 80% adherence to hormones declined from 81% (year 1) to 45% (year 6) in the hormone group, and increased from 0% (year 1) to 8% (year 6) in the placebo group. MAIN OUTCOME MEASURES The primary outcome was nonfatal myocardial infarction and CHD death. Secondary cardiovascular events were coronary revascularization, hospitalization for unstable angina or congestive heart failure, nonfatal ventricular arrhythmia, sudden death, stroke or transient ischemic attack, and peripheral arterial disease. RESULTS There were no significant decreases in rates of primary CHD events or secondary cardiovascular events among women assigned to the hormone group compared with the placebo group in HERS, HERS II, or overall. The unadjusted relative hazard (RH) for CHD events in HERS was 0.99 (95% confidence interval [CI], 0.81-1.22); HERS II, 1.00 (95% CI, 0.77-1.29); and overall, 0.99 (0.84-1.17). The overall RHs were similar after adjustment for potential confounders and differential use of statins between treatment groups (RH, 0.97; 95% CI, 0.82-1.14), and in analyses restricted to women who were adherent to randomized treatment assignment (RH, 0.96; 95% CI, 0.77-1.19). CONCLUSIONS Lower rates of CHD events among women in the hormone group in the final years of HERS did not persist during additional years of follow-up. After 6.8 years, hormone therapy did not reduce risk of cardiovascular events in women with CHD. Postmenopausal hormone therapy should not be used to reduce risk for CHD events in women with CHD.

Abstract
OBJECTIVE To distinguish the effects of drug abuse, mental disorders, and problem drinking on antiretroviral therapy (ART) and highly active ART (HAART) use. DESIGN Prospective population-based probability sample of 2,267 (representing 213,308) HIV-infected persons in care in the United States in early 1996. MEASUREMENTS Self-reported ART from first (January 1997-July 1997) to second (August 1997-January 1998) follow-up interviews. Drug abuse/dependence, severity of abuse, alcohol use, and probable mental disorders assessed in the first follow-up interview. Adjusted odds ratios (AORs) and 95% confidence intervals (CIs) estimated from weighted models for 1) receipt of any ART, and 2) receipt of HAART among those on ART. RESULTS Of our study population, ART was reported by 90% and HAART by 61%. Over one third had a probable mental disorder and nearly half had abused any drugs, but drug dependence (9%) or severe abuse (10%) was infrequent. Any ART was less likely for persons with dysthymia (AOR, 0.74; CI, 0.58 to 0.95) but only before adjustment for drug abuse. After full adjustment with mental health and drug abuse variables, any ART was less likely for drug dependence (AOR, 0.58; CI, 0.34 to 0.97), severe drug abuse (AOR, 0.52; CI, 0.32 to 0.87), and HIV risk from injection drug use (AOR, 0.55; CI, 0.39 to 0.79). Among drug users on ART, only mental health treatment was associated with HAART (AOR, 1.57; CI, 1.11 to 2.08). CONCLUSIONS Drug abuse-related factors were greater barriers to ART use in this national sample than mental disorders but once on ART, these factors were unrelated to type of therapy.

Abstract
CONTEXT High-dose chemotherapy poses considerable challenges to emesis management. Although prior studies suggest that acupuncture may reduce nausea and emesis, it is unclear whether such benefit comes from the nonspecific effects of attention and clinician-patient interaction. OBJECTIVE To compare the effectiveness of electroacupuncture vs minimal needling and mock electrical stimulation or antiemetic medications alone in controlling emesis among patients undergoing a highly emetogenic chemotherapy regimen. DESIGN Three-arm, parallel-group, randomized controlled trial conducted from March 1996 to December 1997, with a 5-day study period and a 9-day follow-up. SETTING Oncology center at a university medical center. PATIENTS One hundred four women (mean age, 46 years) with high-risk breast cancer. INTERVENTIONS Patients were randomly assigned to receive low-frequency electroacupuncture at classic antiemetic acupuncture points once daily for 5 days (n = 37); minimal needling at control points with mock electrostimulation on the same schedule (n = 33); or no adjunct needling (n = 34). All patients received concurrent triple antiemetic pharmacotherapy and high-dose chemotherapy (cyclophosphamide, cisplatin, and carmustine). MAIN OUTCOME MEASURES Total number of emesis episodes occurring during the 5-day study period and the proportion of emesis-free days, compared among the 3 groups. RESULTS The number of emesis episodes occurring during the 5 days was lower for patients receiving electroacupuncture compared with those receiving minimal needling or pharmacotherapy alone (median number of episodes, 5, 10, and 15, respectively; P<.001). The electroacupuncture group had fewer episodes of emesis than the minimal needling group (P<.001), whereas the minimal needling group had fewer episodes of emesis than the antiemetic pharmacotherapy alone group (P =.01). The differences among groups were not significant during the 9-day follow-up period (P =.18). CONCLUSIONS In this study of patients with breast cancer receiving high-dose chemotherapy, adjunct electroacupuncture was more effective in controlling emesis than minimal needling or antiemetic pharmacotherapy alone, although the observed effect had limited duration.

Abstract
OBJECTIVE The objective of this work was to identify similarities and differences in primary attending physicians' (generalists' versus oncologists') care practices and outcomes for seriously ill hospitalized patients with malignancy. DESIGN This was a prospective cohort study (SUPPORT project). SETTING Subjects were recruited from 5 US teaching hospitals; data were gathered from 1989 to 1994. SUBJECTS Included in the study was a matched sample of 642 hospitalized patients receiving care for non-small-cell lung cancer, colon cancer metastasized to the liver, or multiorgan system failure associated with malignancy with either a generalist or an oncologist as the primary attending physician. MEASUREMENTS Care practices and patient outcomes were determined from hospital records. Length of survival was identified with the National Death Index. Physicians' perceptions of patient's prognosis, preference for cardiopulmonary resuscitation (CPR), and length of relationship were assessed by interview. A propensity score for receiving care from an oncologist was constructed. After propensity-based matching of patients, practices and outcomes of oncologists' and generalists' patients were assessed through group comparison techniques. RESULTS Generalist and oncologist attendings showed comparable care practices, including the number of therapeutic interventions, eg, "rescue care" and chemotherapy, and the number of care topics discussed with patients/ families. Length of stay, discharge to supportive care, readmission, total hospital costs, and survival rates were similar. For both physician groups, perception of patients' wish for CPR was associated with rescue care (P < 0.03), and such care was related to higher hospital costs (P < 0.000). Poorer prognostic estimates predicted aggressiveness-of-care discussions by both types of physicians. Length of the patient-doctor relationship was associated with oncologists' care practices. More documented discussion about aggressiveness of care was related to higher hospital costs and shorter survival for patients in both physician groups (P < 0.001). CONCLUSIONS Generalists and oncologists showed similar care practices and outcomes for comparable hospitalized late-stage cancer patients. Physicians' perceptions about patients' preferences for CPR and prognosis influenced decision making and outcomes for patients in both physician groups. Length of relationship with patients was associated only with oncologists' care practices. Rescue care increased hospital costs but had no effect on patient survival. Future studies should compare physicians' palliative care as well as acute-care practices in both inpatient and ambulatory care settings. Patients' end-of-life quality and interchange between physician groups should also be documented and compared.

Abstract
OBJECTIVE To employ the behavioral model of health services use in examining the extent to which predisposing, enabling, and need factors explain the treatment of the HIV-positive population in the United States with highly active antiretroviral therapy (HAART). DATA SOURCE A national probability sample of 2,776 adults under treatment for human immunodeficiency virus (HIV) infection. STUDY DESIGN The article uses data from the baseline and six-month follow-up surveys. The key independent variables describe vulnerable population groups including women, drug users, ethnic minorities, and the less educated. The dependent variable is whether or not a respondent received HAART by December 1996. DATA COLLECTION All interviews were conducted using computer-assisted personal interview instruments designed for this study. Ninety-two percent of the baseline interviews were conducted in person and the remainder over the telephone. PRINCIPAL FINDINGS A multistage logit regression shows that the predisposing factors that have previously described vulnerable groups in the general population with limited access to medical care also define HIV-positive groups who are less likely to gain early access to HAART including women, injection drug users, African Americans, and the least educated (odds ratios, controlling for need, ranged from 0.35 to 0.59). CONCLUSIONS Those HIV-positive persons with the greatest need (defined by a low CD4 count) are most likely to have early access to HAART, which suggests equitable access. However, some predisposing and enabling variables continue to be important as well, suggesting inequitable access, especially for African Americans and lower-income groups. Policymakers and clinicians need to be sensitized to the continued problems of African Americans and other vulnerable populations in gaining access to such potentially beneficial therapies. Higher income, anonymous test sites, and same-day appointments are important enabling resources.

Abstract
BACKGROUND Previous studies suggest that specialty care is more costly but may produce improved outcomes for patients with acute cardiac illnesses. OBJECTIVE To determine whether patients with congestive heart failure who are cared for by cardiologists experienced differences in costs, care patterns, and survival compared with patients of generalists. DESIGN Prospective cohort study. SETTING 5 U.S. teaching hospitals between 1989 and 1994. PATIENTS 1298 patients hospitalized with an exacerbation of congestive heart failure. MEASUREMENTS Hospital costs; average daily Therapeutic Intervention Scoring System (TISS) score; and survival censored at 30, 180, and 365 days and 31 December 1994. RESULTS Compared with patients of generalists, patients of cardiologists were younger (mean age, 63.3 and 71.4 years; P < 0.001) and had lower Acute Physiology Scores at the time of admission (35.1 and 36.7; P < 0.001) but were more likely to have a history of ventricular arrhythmias (21.0% and 10.2%; P < 0.001). At 6 months, 201 (27%) patients of cardiologists and 149 (27%) patients of generalists had died. After adjustment for sociodemographic characteristics and severity of illness, patients of cardiologists incurred costs that were 42.9% (95% CI, 27.8% to 59.8%) higher and average daily TISS scores that were 2.83 points (CI, 1.96 to 3.68 points) higher than those of patients of generalists. Patients of cardiologists were more likely to undergo right-heart catheterization (adjusted odds ratio, 2.9 [CI, 1.7 to 4.9]) or cardiac catheterization (adjusted odds ratio, 3.9 [CI, 2.4 to 6.2]) and had higher odds for transfer to an intensive care unit and electrocardiographic monitoring. Adjusted survival did not differ significantly between groups at 30 days; however, there was a trend toward improved survival among patients of cardiologists at 1 year (adjusted relative hazard, 0.82 [CI, 0.65 to 1.04]) and at maximum follow-up (adjusted relative hazard, 0.80 [CI, 0.66 to 0.96]). CONCLUSIONS In this observational study of patients hospitalized with congestive heart failure, cardiologist care was associated with greater costs and resource use and no difference in survival at 30 days of follow-up. Whether the trend toward better survival at longer follow-up represents differences in care or unadjusted illness severity is uncertain.

Abstract
BACKGROUND Patient age may influence decisions to withhold life-sustaining treatments, independent of patients' preferences for or ability to benefit from such treatments. Controversy exists about the appropriateness of using age as a criterion for making treatment decisions. OBJECTIVE To determine the effect of age on decisions to withhold life-sustaining therapies. DESIGN Prospective cohort study. SETTING Five medical centers participating in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). PATIENTS 9105 hospitalized adults who had one of nine illnesses associated with an average 6-month mortality rate of 50%. MEASUREMENTS Outcomes were the presence and timing of decisions to withhold ventilator support, surgery, and dialysis. Adjustment was made for sociodemographic characteristics, prognoses, baseline function, patients' preferences for life-extending care, and physicians' understanding of patients' preferences for life-extending care. RESULTS The median patient age was 63 years; 44% of patients were women, and 53% survived to 180 days. In adjusted analyses, older age was associated with higher rates of withholding each of the three life-sustaining treatments studied. For ventilator support, the rate of decisions to withhold therapy increased 15% with each decade of age (hazard ratio, 1.15 [95% CI, 1.12 to 1.19]); for surgery, the increase per decade was 19% (hazard ratio, 1.19 [CI, 1.12 to 1.27]); and for dialysis, the increase per decade was 12% (hazard ratio, 1.12 [CI, 1.06 to 1.19]). Physicians underestimated older patients' preferences for life-extending care; adjustment for this underestimation resulted in an attenuation of the association between age and decisions to withhold treatments. CONCLUSION Even after adjustment for differences in patients' prognoses and preferences, older age was associated with higher rates of decisions to withhold ventilator support, surgery, and dialysis.

Abstract
PURPOSE To describe characteristics, outcomes, and decision making in patients with colorectal cancer metastatic to the liver, and to examine the relationship of doctor-patient communication with patient understanding of prognosis and physician understanding of patients' treatment preferences. PATIENTS AND METHODS The Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) was a prospective cohort study conducted at five teaching hospitals in the United States between 1989 and 1994. Participants in this study were hospitalized patients 18 years of age or older with known liver metastases who had been diagnosed with colorectal cancer at least 1 month earlier. Data were collected by patient interview and chart review at study entry; patients were interviewed again at 2 and 6 months. Data collected by physician interview included estimates of survival and impressions of patients' preferences for cardiopulmonary resuscitation (CPR). Patients and physicians were also asked about discussions about prognosis and resuscitation preferences. RESULTS We studied 520 patients with metastatic colorectal cancer (median age 64, 56% male, 80% white, 2-month survival 78%, 6-month survival 56%). Quality of life (62% "good" to "excellent") and functional status (median number of disabilities = 0) were high at study entry and remained so among interviewed survivors at 2 and 6 months. Of 339 patients with available information, 212 (63%) of 339 wanted CPR in the event of a cardiopulmonary arrest. Factors independently associated with preference for resuscitation included younger age, better quality of life, absence of lung metastases, and greater patient estimate of 2-month prognosis. Of the patients who preferred not to receive CPR, less than half had a do-not-resuscitate note or order written. Patients' self-assessed prognoses were less accurate than those of their physicians. Physicians incorrectly identified patient CPR preferences in 30% of cases. Neither patient prognostication nor physician understanding of preferences were significantly better when discussions were reported between doctors and patients. CONCLUSIONS A majority of patients with colorectal cancer have preferences regarding end of life care. The substantial misunderstanding between patients and their physicians about prognosis and treatment preferences appears not to be improved by direct communication. Future research focused on enhancing the effectiveness of communication between patients and physicians about end of life issues is needed.

Abstract
CONTEXT Previous studies have documented that cancer patients tend to overestimate the probability of long-term survival. If patient preferences about the trade-offs between the risks and benefits associated with alternative treatment strategies are based on inaccurate perceptions of prognosis, then treatment choices may not reflect each patient's true values. OBJECTIVE To test the hypothesis that among terminally ill cancer patients an accurate understanding of prognosis is associated with a preference for therapy that focuses on comfort over attempts at life extension. DESIGN Prospective cohort study. SETTING Five teaching hospitals in the United States. PATIENTS A total of 917 adults hospitalized with stage III or IV non-small cell lung cancer or colon cancer metastatic to liver in phases 1 and 2 of the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). MAIN OUTCOME MEASURES Proportion of patients favoring life-extending therapy over therapy focusing on relief of pain and discomfort, patient and physician estimates of the probability of 6-month survival, and actual 6-month survival. RESULTS Patients who thought they were going to live for at least 6 months were more likely (odds ratio [OR], 2.6; 95% confidence interval [CI], 1.8-3.7) to favor life-extending therapy over comfort care compared with patients who thought there was at least a 10% chance that they would not live 6 months. This OR was highest (8.5; 95% CI, 3.0-24.0) among patients who estimated their 6-month survival probability at greater than 90% but whose physicians estimated it at 10% or less. Patients overestimated their chances of surviving 6 months, while physicians estimated prognosis quite accurately. Patients who preferred life-extending therapy were more likely to undergo aggressive treatment, but controlling for known prognostic factors, their 6-month survival was no better. CONCLUSIONS Patients with metastatic colon and lung cancer overestimate their survival probabilities and these estimates may influence their preferences about medical therapies.

Abstract
BACKGROUND Renal failure requiring dialysis in the setting of hospitalization for serious illness is a poor prognostic sign, and dialysis and aggressive care are sometimes withheld. OBJECTIVE To evaluate the clinical outcomes and cost-effectiveness of initiating dialysis and continuing aggressive care for seriously ill hospitalized patients. DESIGN Prospective cohort study and cost-effectiveness analysis. SETTING Five geographically diverse teaching hospitals. PATIENTS 490 patients (median age, 61 years; 58% women) enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) in whom dialysis was initiated. MEASUREMENTS Survival, functional status, quality of life, and health care costs. Life expectancy was estimated by extrapolating survival data (up to 4.4 years of follow-up) using a declining exponential function. Utilities (quality-of-life weights) were estimated by using time-tradeoff questions. Costs were based on data from SUPPORT and published Medicare data. RESULTS Median duration of survival was 32 days, and only 27% of patients were alive after 5 months. Survivors reported a median of one dependency in activities of daily living, and 62% rated their quality of life as "good" or better. Overall, the estimated cost per quality-adjusted life-year saved by initiating dialysis and continuing aggressive care rather than withholding dialysis and allowing death to occur was $128,200. For the 103 patients in the worst prognostic category, the estimated cost per quality-adjusted life-year was $274,100; for the 94 patients in the best prognostic category, the cost per quality-adjusted life-year was $61,900. CONCLUSIONS For the few patients who survived, clinical outcomes were fairly good. With the exception of patients with the best prognoses, however, the cost-effectiveness of initiating dialysis and continuing aggressive care far exceeded $50,000 per quality-adjusted life-year, a commonly cited threshold for cost-effective care.

Abstract
OBJECTIVE Would increasing the documentation of advance directives (ADs) lead to a reduction in resource utilization? We examined this question by conducting three secondary analyses: (1) we tested for a change in resource use among those who died in the hospital at a time before and after an intervention that increased the documentation of ADs in the medical record; (2) we replicated analyses of published studies that reported an association of chart documentation of ADs and hospital resource use; and (3) we examined whether a potential explanation of the observed association is biased documentation of ADs among patients who have completed an AD. DESIGN Replication of analysis of previous published studies using data from a prospective cohort study and block-randomized controlled trial. SETTING Five teaching hospitals in the United States. PATIENTS A total of 9105 seriously ill patients were enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT), including 4301 patients in the 2 years (1989-91) before the Patient Self-Determination Act (PSDA) and 4804 in the 2 years (1992-94) after the PSDA implementation, with 2652 patients receiving the intervention and 2152 serving as controls. INTERVENTIONS The SUPPORT intervention provided a nurse to facilitate communication among patients, surrogates, and physicians about preferences for and outcomes of treatments. Documenting existing advance directives was also one of this nurse's tasks. The Patient Self-Determination Act required that health care institutions inquire about and document existing advance directives at the time of hospital admission. MEASUREMENT Hospital resource use was derived from the Therapeutic Intensity Scoring System and hospital length of stay, converted into 1994 dollars. RESULTS Chart documentation of existing advance directives at the time of study admission increased with both the PSDA and the SUPPORT intervention. We found that intervention patients were more likely to have pre-existing ADs documented. Despite this increase, there was no corresponding change in hospital resource use for those who died during the enrollment hospitalization. Replication of analyses from published studies using data from the block randomized controlled trial found that ADs documented by the third day of serious illness were associated with a 23% reduction in hospital resource use among control patients ($21,284 with ADs documented compared with $26,127 without, 95% CI 1-48% reduction). However, this association was not observed among intervention patients, who had more pre-existing ADs documented in the medical record. Intervention patients with early documentation of ADs showed a trend toward greater cost ($28,017 compared with $24,178 among those without AD documentation, 95% CI 0-25% increase). The rate of documentation and characteristics of those with documentation differed between control and intervention patients. Intervention patients were more likely (as reported by patient or surrogate interview) to have ADs documented in the medical record by the third day (55% vs 32%, P < .001). In contrast to intervention patients, control patients who were older, less wealthy, less educated, more likely to prefer to forgo CPR, and more likely to want life-sustaining treatment limited had their ADs documented. These associations were not found among intervention patients when comparison was made between those with and those without an AD documented in the medical record. CONCLUSION Increasing the documentation of pre-existing ADs was not associated with a reduction in hospital resource use. ADs documented without further intervention by the third day of a serious illness were associated with decreased hospital resource use. However, we did not find this association with an intervention that increased AD documentation. One potential explanation of these findings is that classification of those with an AD was based on cha

Abstract
OBJECTIVE To assess the effectiveness of written advance directives (ADs) in the care of seriously ill, hospitalized patients. In particular, to conduct an assessment after ADs were promoted by the Patient Self-Determination Act (PSDA) and enhanced by the effort to improve decision-making in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT), focusing upon the impact of ADs on decision-making about resuscitation. DESIGN Observational cohort study conducted for 2 years before (PRE) and for 2 years after (POST) the PSDA, with a randomized, controlled trial of an additional intervention to improve decision-making after PSDA (POST+SUPPORT). SETTING Five teaching hospitals in the United States. PATIENTS A total of 9105 seriously ill patients treated in five teaching hospitals. INTERVENTIONS The PSDA mandated patient education about ADs at hospital entry and documentation of ADs in the medical record. The SUPPORT intervention, in addition, provided a nurse to facilitate communication among patients, surrogates, and physicians about preferences for and outcomes of treatment alternatives and, when clinically appropriate, to encourage completion and utilization of ADs. MEASUREMENTS Interviews were conducted with patients, surrogates, and attending physicians about awareness, completion, and impact of ADs. Medical records were reviewed for discussion about preferences concerning resuscitation, timing and writing of "Do Not Resuscitate" (DNR) orders, evidence of ADs, and the use or forgoing of resuscitation at the time of death. RESULTS In the three cohorts, PRE, POST, and POST+SUPPORT, average age was 63. One-quarter of patients died during the initial hospitalization, one-half were dead within 6 months, and one-half were unconscious for their last 3 days. Before the PSDA (PRE), 62% were familiar with a living will, and 21% had an AD. These rates were similar for the POST and POST+SUPPORT cohorts. Just 36 (6%) of these directives were mentioned in the medical records for PRE, but a stable 35% were documented for POST, and POST+SUPPORT had an increasing rate averaging 78% (P < .001). As previously reported for PRE patients, the POST patients with and without ADs had no significant differences in the rates of medical record documentation of discussions about resuscitation (33% vs 38%, POST without AD vs POST with AD), DNR orders among those who wanted to forgo resuscitation (54% vs 58%), and attempted resuscitations at death (17% vs 9%). The POST+SUPPORT patients had similar results, with no evidence that the intervention enhanced the effect of ADs on these three measures of resuscitation decision-making. Patients with ADs more often reported that preferences about resuscitation were discussed with a physician (e.g., for POST patients, 30% for those with no AD and 43% for those with an AD, P < .05). Only 12% of patients with ADs had talked with a physician when completing the AD. Only 42% reported ever having discussed the AD with their physician. By the second study week, only one in four physicians was aware of patients' ADs. CONCLUSIONS In these seriously ill patients, ADs did not substantially enhance physician-patient communication or decision-making about resuscitation. This lack of effect was not altered by the PSDA or by the enhanced efforts in SUPPORT, although these interventions each substantially increased documentation of existing ADs. Current practice patterns indicate that increasing the frequency of ADs is unlikely to be a substantial element in improving the care of seriously ill patients. Future work to improve decision-making should focus upon improving the current pattern of practice through better communication and more comprehensive advance care planning.

Abstract
OBJECTIVE To evaluate whether the lack of effect of advance directives (ADs) on decision-making in SUPPORT might arise, in part, from the content of the actual documents. DESIGN Advance directives placed in the medical records were abstracted for date of completion and content of additional written instructions. We examined directives with instructions to forgo life-sustaining treatment in the current state of health to determine whether care given was consistent with preferences noted in those directives. SETTINGS Five teaching hospitals in the United States. PATIENTS A total of 4804 patients with at least one of nine serious illnesses were admitted to five teaching hospitals in the 2 years following implementation of the Patient Self-Determination Act. Patients were part of a randomized controlled trial to improve decision-making and outcomes. RESULTS From the medical records of 4804 patients, a total of 688 directives were collected from 569 patients. The majority of these directives (66%) were durable powers of attorney; in addition, 31% were standard living wills or other forms of written instructions (3%). Only 90 documents (13%) provided additional instructions for medical care beyond naming a proxy or stating the preferences of a standard living will. Only 36 contained specific instructions about the use of life-sustaining medical treatment, and only 22 of these directed forgoing life-sustaining treatment in the patient's current situation. For these, the treatment course was consistent with the instruction for nine patients. In two cases, patients may have changed an inconsistent directive after discussion with hospital staff. CONCLUSION Advance directives placed in the medical records of seriously ill patients often did not guide medical decision-making beyond naming a healthcare proxy or documenting general preferences in a standard living will format. Even when specific instructions were present, care was potentially inconsistent in half of the cases.

Abstract
BACKGROUND Alleviating the problems faced by dying persons and their families has drawn substantial public attention, but little is known about the experience of dying. OBJECTIVE To characterize the experience of dying from the perspective of surrogate decision makers, usually close family members (89%). DESIGN Prospective cohort study. SETTING Five teaching hospitals. PATIENTS Persons who had one of nine serious medical conditions or were 80 years of age or older who died and for whom a surrogate decision maker completed an interview about the death. MEASUREMENTS Medical records were reviewed and surrogate decision makers were interviewed. RESULTS 4124 of 9105 seriously ill patients died (46%); 408 of 1176 elderly patients died (35%). The patients' family members were interviewed after 3357 persons (73%) had died. Of 1541 patients who survived the enrollment hospitalization, 46% died during a later hospitalization. In the last 3 days of life, 55% of patients were conscious. Among these patients, pain, dyspnea, and fatigue were prevalent. Four in 10 patients had severe pain most of the time. Severe fatigue affected almost 8 in 10 patients. More than 1 in 4 patients had moderate dysphoria. Sixty-three percent of patients had difficulty tolerating physical or emotional symptoms. Overall, 11% of patients had a final resuscitation attempt. A ventilator was used in one fourth of patients, and a feeding tube was used in four tenths of patients. Most patients (59%) were reported to prefer a treatment plan that focused on comfort, but care was reported to be contrary to the preferred approach in 10% of cases. CONCLUSIONS Most elderly and seriously ill patients died in acute care hospitals. Pain and other symptoms were commonplace and troubling to patients. Family members believed that patients preferred comfort, but life-sustaining treatments were often used. These findings indicate important opportunities to improve the care of dying patients.

Factors associated with do-not-resuscitate orders: patients' preferences, prognoses, and physicians' judgments. SUPPORT Investigators. Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment. Ann Intern Med 1996; 125:284-93.

Abstract
BACKGROUND Medical treatment decisions should be based on the preferences of informed patients or their proxies and on the expected outcomes of treatment. Because seriously ill patients are at risk for cardiac arrest, examination of do-not-resuscitate (DNR) practices affecting them provides useful insights into the associations between various factors and medical decision making. OBJECTIVE To examine the association between patients' preferences for resuscitation (along with other patient and physician characteristics) and the frequency and timing of DNR orders. DESIGN Prospective cohort study. SETTING 5 teaching hospitals. PATIENTS 6802 seriously ill hospitalized patients enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatment (SUPPORT) between 1989 and 1994. MEASUREMENTS Patients and their surrogates were interviewed about patients' cardiopulmonary resuscitation preferences, medical records were reviewed to determine disease severity, and a multivariable regression model was constructed to predict the time to the first DNR order. RESULTS The patients' preference for cardiopulmonary resuscitation was the most important predictor of the timing of DNR orders, but only 52% of patients who preferred not to be resuscitated actually had DNR orders written. The probability of surviving for 2 months was the next most important predictor of the timing of DNR orders. Although DNR orders were not linearly related to the probability of surviving for 2 months, they were written earlier and more frequently for patients with a 50% or lower probability of surviving for 2 months. Orders were written more quickly for patients older than 75 years of age, regardless of prognosis. After adjustment for these and other influential patient characteristics, the use and timing of DNR orders varied significantly among physician specialties and among hospitals. CONCLUSIONS Patients' preferences and short-term prognoses are associated with the timing of DNR orders. However, the substantial variation seen among hospital sites and among physician specialties suggests that there is room for improvement. In this study, DNR orders were written earlier for patients older than 75 years of age, regardless of prognosis. This finding suggests that physicians may be using age in a way that is inconsistent with the reported association between age and survival. The process for making decisions about DNR orders needs to be improved if such orders are to routinely and accurately reflect patients' preferences and probable outcomes.
