Abstract
PURPOSE To examine nurse-patient communication about preferences for cardiopulmonary resuscitation (CPR). DESIGN Prospective cohort. Sampled were patients and nurses caring for patients enrolled in SUPPORT (1989-91), a multicenter study of seriously-ill hospitalized adults at four U.S. hospitals. METHODS Information about patient preferences was obtained by interviews with patients and their designated surrogates. For selected patients, nurses were interviewed prospectively about their understanding of patients' preferences and whether they discussed these preferences with their patients. Nurse demographic information was obtained by questionnaire. Additional patient data were obtained by interview and chart review. Logistic regression was used to identify independent correlates of nurse-patient communication and nurses' understanding of patients' preferences. FINDINGS For 1,763 study patients, 1,427 nurse interviews (response rate 81%) were obtained. The median age of interviewed nurses was 29 years; 96% were women, 68% had a bachelor's or master's degree, and 62% had worked for 5 years or more as a nurse. Nurses reported discussions about CPR with 13% of their patients, and these discussions were more likely if the nurse thought the patient did not want CPR (adjusted odds ratio [AOR] 2.68; 95% CI 1.84 to 3.90), if the nurse had spent more time with the patient (AOR 1.05; 95% CI 1.02 to 1.08) per 5 additional days, if the patient had metastatic cancer (AOR 3.56; 95% CI 1.86 to 6.78), or if the patient was in an intensive care unit at the time of study entry (AOR 2.08; 95% CI 1.26 to 3.42). Diagnosis and study site were also associated with nurses' reports of discussions with patients. Of 551 patients with available data, 58% (n = 317) wanted CPR and 30% (n = 164) did not. Nurses understood patients' CPR preferences correctly for 74% of the patients. Nurses were more likely to understand patients' preferences to forego CPR if the patient was 75 years of age or older (AOR 6.6; 95% CI 2.0 to 22.0) or if the nurse and patient had discussed the patient's preferences (AOR 25.3; 95% CI 6.5 to 98.6) or if the patient had cancer (AOR 10.9; 95% CI 2.3 to 50.1). Nurses' understanding of patients' preferences for CPR was no better than that of physicians or patients' surrogate decision-makers. CONCLUSIONS In this sample of seriously ill hospitalized adults, discussions between patients and nurses about CPR were infrequent. Nurses' understanding of patients' preferences for care was similar to that of physicians and patients' surrogate decision-makers. Educational interventions should focus on increasing the frequency of nurse-patient discussions about end-of-life care and improving nurses' understanding of patients' preferences for care.

Abstract
Depression is common among HIV-infected patients, but little is known about risk factors for depression in this population. Several studies before protease inhibitors became available have reported inconsistent associations between depression and disease severity. Delivering high quality HIV care includes adequate detection and treatment of depression. The objective of this study was to describe the prevalence and correlates of depression among a contemporary group of HIV-infected patients. The setting and design for the study was a chart abstraction for HIV-infected patients in a primary care practice in Boston, Mass, in June 1997. Among 275 HIV-infected patients, depression was documented in 147 patient charts (53%), half of whom (n = 73, 27%) also received antidepressant medications. We used multivariable logistic regression to identify risk factors for depression among patients with both a chart diagnosis of depression and current antidepressant medication use. We observed increased risk of depression among patients with a history of substance use (odds ratio 2.7, 95% confidence interval 1.5-4.7), recent medical hospitalization (2.6, 1.4-5.0), and homosexual risk behavior (2.1, 1.1-4.2). Depression remains a common problem for HIV-infected patients, particularly among those with history of substance abuse, medical hospitalization, or homosexual risk behavior. Routine screening for depression in this population with special attention to those at higher risk may offer opportunities for earlier diagnosis and treatment.

Abstract
BACKGROUND The effect of weight control concerns on smoking among adults is unclear. We examined the association between smoking behavior and weight control efforts among US adults. METHODS A total of 17 317 adults responded to the Year 2000 Supplement of the 1995 National Health Interview Survey (83% combined response rate). Respondents provided sociodemographic and health information, including their smoking history and whether they were trying to lose weight, maintain weight, or gain weight. RESULTS Rates of smoking were lower among adults who were trying to lose or maintain weight than among those not trying to control weight (25% vs 31%; P<.001). After adjustment for sex, race, education, income, marital status, region of the country, and body mass index, the relationship between trying to lose weight and current smoking varied according to age. Among adults younger than 30 years, those trying to lose weight were more likely to smoke currently (odds ratio, 1.36 [95% confidence interval, 1.09-1.70]), whereas older adults trying to lose weight were as likely or less likely to smoke compared with adults not trying to control weight. After adjustment, smokers of all ages who were trying to lose weight were more likely to express a desire to quit smoking. Results were similar after stratification by sex and body mass index. CONCLUSIONS Adults younger than 30 years are more likely to smoke if they are trying to lose weight. However, smokers of all ages who are trying to lose weight are more likely to want to stop smoking. Patients' weight control efforts should not discourage clinicians from counseling about smoking cessation. Education about smoking and healthy weight control methods should target young adults.

Abstract
We surveyed 241 board-certified internists affiliated with a large teaching hospital (Boston, Mass) before implementing a hospitalist service to determine attitudes towards providing inpatient care and the hospitalist model. Of physicians surveyed, 66% responded. Most disagreed that inpatient care is "an inefficient use of my time," only 10% felt a hospitalist service would improve patient satisfaction, and 54% felt it would hurt patient-doctor relationships. Multivariable analyses suggest that physicians physically furthest from their inpatient site were had more favorable attitudes toward the hospitalist model; more experienced and busier physicians were more negative. Future investigations should determine strategies for implementing the hospitalist model which address physicians' concerns.

Abstract
OBJECTIVE This study presents data on the use of complementary and alternative therapies to treat anxiety and depression in the United States. METHOD The data came from a nationally representative survey of 2,055 respondents (1997-1998) that obtained information on the use of 24 complementary and alternative therapies for the treatment of specific chronic conditions. RESULTS A total of 9.4% of the respondents reported suffering from "anxiety attacks" in the past 12 months; 7.2% reported "severe depression." A total of 56.7% of those with anxiety attacks and 53.6% of those with severe depression reported using complementary and alternative therapies to treat these conditions during the past 12 months. Only 20.0% of those with anxiety attacks and 19.3% of those with severe depression visited a complementary or alternative therapist. A total of 65.9% of the respondents seen by a conventional provider for anxiety attacks and 66.7% of those seen by a conventional provider for severe depression also used complementary and alternative therapies to treat these conditions. The perceived helpfulness of these therapies in treating anxiety and depression was similar to that of conventional therapies. CONCLUSIONS Complementary and alternative therapies are used more than conventional therapies by people with self-defined anxiety attacks and severe depression. Most patients visiting conventional mental health providers for these problems also use complementary and alternative therapies. Use of these therapies will likely increase as insurance coverage expands. Asking patients about their use could prevent adverse effects and maximize the usefulness of therapies subsequently proven to be effective.

Abstract
CONTEXT Various forms of "energy healing" have become popular in the United States. OBJECTIVE To test the assertion that an energy healer can, without physical contact, distinguish the presence or absence of internal organ pathology in individuals who lack overt physical findings. DESIGN Observational randomized study, in which we tested the assertion by a well-recognized alternative healer that he had particular skill in using energy transfer to detect the presence or absence of fertility disorders in women. PATIENTS Convenience sample of 37 women, 28 of whom had documented pathology resulting in infertility, and 9 of whom were fertile. OUTCOMES The healer was provided with no medical history and performed diagnostic evaluations without physical contact with the blindfolded, clothed, and silent subjects. We compared to random chance the ability of the healer to establish a diagnosis of fertility or fertility disorder. SETTING Teaching hospital. MAIN RESULTS The healer was unable to distinguish the presence or absence of fertility disorders in the study subjects. CONCLUSION This study points to further need for fair yet rigorous assessment of claims that energy transfer can lead to accurate clinical diagnoses.

Abstract
PURPOSE To review current research and recommendations on weight loss and weight control and provide suggestions for health care providers who furnish weight management counseling. DATA SOURCES Scientific publications, clinical guidelines, and government sources. CONCLUSIONS Research reaffirms the long-held understanding that weight loss can be accomplished only through a reduction in the number of calories consumed and an increase in exercise. Weight maintenance requires life-long behavioral change combining moderate exercise, lower fat intake, increased fruit and vegetable consumption, as well as social support. Fad diets and medications are not the answer to long-term weight maintenance. IMPLICATIONS FOR PRACTICE The essential components of a weight loss or weight management program include: calorie reduction of 300-500 calories per day, appropriate exercise, variety in food choices, increased consumption of grains, fruits, and vegetables, and reduction of fat to no more than 30% of daily calories. Clients should be referred to dietitian and exercise consultants as needed.

Abstract
OBJECTIVES The goal of this study was to determine factors associated with receiving cardiologist care among patients with an acute exacerbation of congestive heart failure. BACKGROUND Because cardiologist care for acute cardiovascular illness may improve care, barriers to specialty care could impact patient outcomes. METHODS We studied 1,298 patients hospitalized with acute exacerbation of congestive heart failure who were cared for by cardiologists or generalist physicians. Using multivariable logistic models we determined factors independently associated with attending cardiologist care. RESULTS Patients were less likely to receive care from a cardiologist if they were black (adjusted odds ratio [AOR] 0.53, 95% confidence interval [CI] 0.35, 0.80), had an income of less than $11,000 (AOR 0.65, 95% CI 0.45, 0.93) or were older than 80 years of age (AOR 0.23, 95% CI 0.12, 0.46). Patients were more likely to receive cardiologist care if they had college level education (AOR 1.89, 95% CI 1.02, 3.51), a history of myocardial infarction (AOR 1.59, 95% CI 1.17, 2.16), a serum sodium less than 133 on admission (AOR 1.96, 95% CI 1.30, 2.95) or a systolic blood pressure less than 90 on admission (AOR 1.97, 95% CI 1.20, 3.24). Patients who stated a desire for life extending care were also more likely to receive care from a cardiologist (AOR 1.40, 95% CI 1.04, 1.90). CONCLUSIONS After adjusting for severity of illness and patient preferences for care, patient sociodemographic factors were strongly associated with receiving care from a cardiologist. Future investigations are required to determine whether these associations represent unmeasured preferences for care or inequities in our health care system.

Abstract
PURPOSE Many patients with acute respiratory failure die despite prolonged and costly treatment. Our objective was to estimate the cost-effectiveness of providing rather than withholding mechanical ventilation and intensive care for patients with acute respiratory failure due to pneumonia or acute respiratory distress syndrome. SUBJECTS AND METHODS We studied 1,005 patients enrolled in a five-center study of seriously ill patients (the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments [SUPPORT]) with acute respiratory failure (pneumonia or acute respiratory distress syndrome and an Acute Physiology Score > or =10) who required ventilator support. We estimated life expectancy based on long-term follow-up of SUPPORT patients. Utilities were estimated using time-tradeoff questions. Costs (in 1998 dollars) were based on hospital fiscal data and Medicare data. RESULTS Of the 963 patients who received ventilator support, 48% survived for at least 6 months. At 6 months, survivors reported a median of 1 dependence in activities of daily living, and 72% rated their quality of life as good, very good, or excellent. Among the 42 patients in whom ventilator support was withheld, the median survival was 3 days. Among patients whose estimated probability of surviving at least 2 months from the time of ventilator support ("prognostic estimate") was 70% or more, the incremental cost per quality-adjusted life-year (QALY) saved by providing rather than withholding ventilator support and aggressive care was $29,000. For medium-risk patients (prognostic estimate 51% to 70%), the incremental cost-effectiveness was $44,000 per QALY, and for high-risk patients (prognostic estimate < or =50%), it was $110,000 per QALY. When assumptions were varied from 50% to 200% of baseline estimates, the results ranged from $19,000 to $48,000 for low-risk patients, from $29,000 to $76, 000 for medium-risk patients, and from $67,000 to $200,000 for high-risk patients. CONCLUSIONS Ventilator support and intensive care for acute respiratory failure due to pneumonia or acute respiratory distress syndrome are relatively cost-effective for patients with >50% probability of surviving 2 months. However, for patients with an expected 2-month survival < or =50%, the cost per QALY is more than threefold greater at >$100,000.

Abstract
PURPOSE Pulmonary embolism (PE), an elusive diagnosis, is detected by a diagnostic work-up that is often guided by the physician's level of clinical suspicion. The ability to accurately assess PE risk on solely clinical grounds may increase with the physician's level of training. This study documented the ability of house staff practicing in an academic teaching hospital to accurately assess the clinical likelihood of PE in patients. METHOD During a seven-month period, all 245 patients with suspected acute PE who had had lung scans ordered via a computerized order-entry system were enrolled in the study. When ordering the lung scans, all physicians (interns, residents, and attending physicians) were required to also enter their levels of clinical suspicion on a scale of 0 to 100. The physicians' levels of clinical suspicion were correlated with the final determinations of PE, and receiver operating characteristic (ROC) curves were calculated for patients' and physicians' subgroups. RESULTS Attending physicians were most able to diagnose PE; residents were moderately able to make the diagnosis, and interns were least able to diagnose PE. The area under the ROC curve for a correct identification of patients with PE was greatest for attending physicians (0.839), intermediate for residents (0.601), and least for interns (0.594). CONCLUSION The ability to correctly assess a patient's likelihood of PE increases with a physician's level of training, suggesting that more senior physicians should be involved in the diagnostic work-up of patients with suspected acute PE. More instruction may help medical students, interns, and residents navigate clinical scenarios in which the diagnosis is uncertain or in which sequential tests must be performed to reach the correct diagnosis.

Abstract
OBJECTIVE To evaluate an Internet-based telemedicine program designed to reduce the costs of care, to provide enhanced medical, informational, and emotional support to families of very low birth weight (VLBW) infants during and after their neonatal intensive care unit (NICU) stay. BACKGROUND Baby CareLink is a multifaceted telemedicine program that incorporates videoconferencing and World Wide Web (WWW) technologies to enhance interactions between families, staff, and community providers. The videoconferencing module allows virtual visits and distance learning from a family's home during an infant's hospitalization as well as virtual house calls and remote monitoring after discharge. Baby CareLink's WWW site contains information on issues that confront these families. In addition, its security architecture allows efficient and confidential sharing of patient-based data and communications among authorized hospital and community users. DESIGN/METHODS A randomized trial of Baby CareLink was conducted in a cohort of VLBW infants born between November 1997 and April 1999. Eligible infants were randomized within 10 days of birth. Families of intervention group infants were given access to the Baby CareLink telemedicine application. A multimedia computer with WWW browser and videoconferencing equipment was installed in their home within 3 weeks of birth. The control group received care as usually practiced in this NICU. Quality of care was assessed using a standardized family satisfaction survey administered after discharge. In addition, the effect of Baby CareLink on hospital length of stay as well as family visitation and interactions with infant and staff were measured. RESULTS Of the 176 VLBW infants admitted during the study period, 30 control and 26 study patients were enrolled. The groups were similar in patient and family characteristics as well as rates of inpatient morbidity. The CareLink group reported higher overall quality of care. Families in the CareLink group reported significantly fewer problems with the overall quality of care received by their family (mean problem score: 3% vs 13%). In addition, CareLink families also reported greater satisfaction with the unit's physical environment and visitation policies (mean problem score: 13% vs 50%). The frequency of family visits, telephone calls to the NICU, and holding of the infant did not differ between groups. The duration of hospitalization until ultimate discharge home was similar in the 2 groups (68.5 +/- 28.3 vs 70.6 +/- 35.6 days). Among infants born weighing <1000 g (n = 31) there was a tendency toward shorter lengths of stay (77.4 +/- 26.2 vs 93.1 +/- 35.6 days). All infants in the CareLink group were discharged directly to home whereas 6/30 (20%) of control infants were transferred to community hospitals before ultimate discharge home. CONCLUSIONS CareLink significantly improves family satisfaction with inpatient VLBW care and definitively lowers costs associated with hospital to hospital transfer. Our data suggest the use of telemedicine and the Internet support the educational and emotional needs of families facilitating earlier discharge to home of VLBW infants. We believe that further extension of the Baby CareLink model to the postdischarge period will significantly improve the coordination and efficiency of care.

Abstract
BACKGROUND The Americans With Disabilities Act defines disability on the basis of physical or mental impairments or external perceptions of impairment. OBJECTIVES The objective of this study was to examine perceptions of disability among people with lower-extremity mobility difficulties. RESEARCH DESIGN This study used a cross-sectional, nationally representative survey, the 1994 to 1995 National Health Interview Survey-Disability (NHIS-D) supplement. Using SAS-callable SUDAAN for all analyses, we produced national population estimates. SUBJECTS This study included 142,572 noninstitutionalized, civilian residents of the United States who were > or =18 years of age, with 80,423 self-respondents and 49,883 proxy respondents. MEASURES We created a 4-level mobility variable using NHIS-D questions about the ability to walk, climb stairs, stand and the use of mobility aids. We examined associations between mobility and answers to 2 questions about self- and external perceptions of disability. RESULTS The results showed that 3.1% (estimated 5.82 million persons) reported major mobility difficulties, including 3.7% of self-respondents and 2.7% of those with proxy respondents. Among persons with major mobility problems, 70.8% perceived themselves as disabled, whereas 64.8% thought other people see them as disabled. Also, 80.5% of manual wheelchair users saw themselves as disabled. Proxies were somewhat more likely to perceive disability than self-respondents, although differences were not generally statistically significant. In multivariable regressions, mobility level was the strongest predictor of self-perceived disability, followed by general health status. CONCLUSIONS Mobility problems increase the likelihood that people will see themselves as disabled, but these perceptions are not universal. Although the schematic of wheelchair users has become an international symbol of disability, many people with serious mobility problems do not view themselves as disabled.

Abstract
In this retrospective study, 37 patients with myelomeningocele who had undergone gait analysis were examined. Patients were divided into groups based on the level of involvement (29 sides: L4; 26 sides: L5; 19 sides: S1-2). Results showed increased knee flexion and associated knee extensor moments with increasing level of neurologic involvement. The mean coronal plane knee position in stance was normal in all groups and not related to coronal plane knee moment. However, there was an increased incidence of a net knee adductor moment in stance with increasing involvement (mean, 0.02 +/-0.18 N.m/kg for the L4 group). The presence of a visual valgus thrust based on video records was not reliable in predicting an abnormal knee coronal plane moment. An abnormal knee adductor moment in stance was most highly related to coronal plane trunk motion (r = -0.62) and not tibial torsion (r = -0.340). Increased transverse plane range of motion of the knee was most highly related to transverse plane trunk motion (r = 0.67).

Abstract
BACKGROUND Hospital discharge diagnoses, coded by use of the International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM), increasingly determine reimbursement and support quality monitoring. Prior studies of coding validity have investigated whether coding guidelines were met, not whether the clinical condition was actually present. OBJECTIVE To determine whether clinical evidence in medical records confirms selected ICD-9-CM discharge diagnoses coded by hospitals. RESEARCH DESIGN AND SUBJECTS Retrospective record review of 485 randomly sampled 1994 hospitalizations of elderly Medicare beneficiaries in Califomia and Connecticut. MAIN OUTCOME MEASURE Proportion of patients with specified ICD-9-CM codes representing potential complications who had clinical evidence confirming the coded condition. RESULTS Clinical evidence supported most postoperative acute myocardial infarction diagnoses, but fewer than 60% of other diagnoses had confirmatory clinical evidence by explicit clinical criteria; 30% of medical and 19% of surgical patients lacked objective confirmatory evidence in the medical record. Across 11 surgical and 2 medical complications, objective clinical criteria or physicians' notes supported the coded diagnosis in >90% of patients for 2 complications, 80% to 90% of patients for 4 complications, 70% to <80% of patients for 5 complications, and <70% for 2 complications. For some complications (postoperative pneumonia, aspiration pneumonia, and hemorrhage or hematoma), a large fraction of patients had only a physician's note reporting the complication. CONCLUSIONS Our findings raise questions about whether the clinical conditions represented by ICD-9-CM codes used by the Complications Screening Program were in fact always present. These findings highlight concerns about the clinical validity of using ICD-9-CM codes for quality monitoring.

Abstract
OBJECTIVE The use of administrative data to identify inpatient complications is technically feasible and inexpensive but unproven as a quality measure. Our objective was to validate whether a screening method that uses data from standard hospital discharge abstracts identifies complications of care and potential quality problems. DESIGN This was a case-control study with structured implicit physician reviews. SETTING Acute-care hospitals in California and Connecticut in 1994. PATIENTS The study included 1,025 Medicare beneficiaries greater than 265 years of age. METHODS Using administrative data, we stratified acute-care hospitals by observed-to-expected complication rates and randomly selected hospitals within each state. We randomly selected cases flagged with 1 of 17 surgical complications and 6 medical complications. We randomly selected controls from unflagged cases. MAIN OUTCOME MEASURE Peer-review organization physicians' judgments about the presence of the flagged complication and potential quality-of-care problems. RESULTS Physicians confirmed flagged complications in 68.4% of surgical and 27.2% of medical cases. They identified potential quality problems in 29.5% of flagged surgical and 15.7% of medical cases but in only 2.1% of surgical and medical controls. The rate of physician-identified potential quality problems among flagged cases exceeded 25% in 9 surgical screens and 1 medical screen. Reviewers noted several potentially mitigating circumstances that affected their judgments about quality, including factors related to the patients' illness, the complexity of the case, and technical difficulties that clinicians encountered. CONCLUSIONS For some types of complications, screening administrative data may offer an efficient approach for identifying potentially problematic cases for physician review. Understanding the basis for physicians' judgments about quality requires more investigation.

Abstract
OBJECTIVES This study examined the validity of the Complications Screening Program (CSP) by testing whether (1) ICD-9-CM codes used to identify a complication are coded completely and accurately and (2) the CSP algorithm successfully separates conditions present on admission from those occurring in the hospital. METHODS We compared diagnosis and procedure codes contained in the Medicare claim with codes abstracted from an independent re-review of more than 1,200 medical records from Connecticut and California. RESULTS Eighty-nine percent of the surgical cases and 84% of the medical cases had their CSP trigger codes corroborated by re-review of the medical record. For 13% of the surgical cases and 58% of the medical cases, the condition represented by the code was judged to be present on admission rather than occurring in-hospital. The positive predictive value of the claim was greater than 80% for the surgical risk pool, suggesting the value of the CSP as a screening tool. CONCLUSIONS The CSP has validity as a screen for most surgical complications but only for 1 medical complication. The CSP does not have validity as a "stand-alone" tool to identify more than a few in-hospital surgery-related events. The addition of an indicator to the Medicare claim to capture the timing of secondary diagnoses would improve the validity of the CSP for identifying both surgical and medical in-hospital events.

Abstract
We aim to develop and validate a questionnaire that examines quality of care from the patient's perspective for limited-English-proficient Asian Americans (AA) of Chinese and Vietnamese descent. We will conduct focus groups of patients to identify issues important to them, with an emphasis on communication and access to care. We will then draft a questionnaire and test its validity using standard survey research methods and direct observation of patient-provider encounters. Subsequent field testing will involve face-to-face patient interviews 1 month after an outpatient visit. We will evaluate alternate modes of administration to test feasibility and to maximize response. The result of our study will be a validated, culturally sensitive, patient-centered instrument that measures health care quality for limited-English-proficient AA patients. Our research will provide a template for developing future quality measures for other vulnerable populations.

Abstract
Although the most important component of an effective scientific exhibit is content, the way in which an exhibit is constructed can greatly influence its overall effectiveness. Choice of format should be determined by carefully analyzing the purpose of one's exhibit, expected audience, and data at hand, as well as type of meeting and funding. Depending on the type of data to be presented and available equipment and budget, the most appropriate style for a scientific exhibit may be a traditional mat board, computer-generated tiles or large-print backboard panel, traditional mat board with viewbox exhibit, matted transparency tiles with viewbox exhibit, or computer-generated large-film display. The authors analyzed 993 of 1, 041 (95.4%) scientific exhibits on display at the 84th RSNA Scientific Assembly and Annual Meeting and categorized each exhibit according to the following characteristics: display type and size, color scheme, display font size, and graphic styles. These characteristics were then correlated with scientific exhibit and design awards as well as invitations for submission to RadioGraphics. Chance of winning an award or being asked to publish the presentation in RadioGraphics was significantly increased for viewbox exhibits (compared with backboard panel exhibits) and for larger exhibits (compared with smaller exhibits).

Abstract
We determined the relationship between patients' socioeconomic status and discussions with their primary care physicians about hormone replacement therapy (HRT) among women facing a decision about HRT within the prior year. The study included telephone interviews and medical record reviews. The setting was a general medicine practice of an urban teaching hospital in Boston, Mass. Women ages 50-65 visiting an academic teaching practice over a 3-month period were selected randomly. Of the 198 potential subjects, 118 (60%) agreed to participate in the survey. We examined discussions of HRT by women who had faced the decision to initiate HRT within the previous year. Women who were not on HRT or had been on therapy for less than 1 year were asked if they had discussed HRT with their physician in the past year. Socioeconomic factors and comorbidities were elicited during the survey and abstracted by chart review. The mean age of the 118 participants was 57; 36% were black, 54% were white, 10% were other race, 17% had less than a high school education, 14% had diabetes, 31% had had a hysterectomy, and 7% had a history of breast cancer. Of the 80 women who did not use HRT or had used it for less than 1 year, 49 (61%) reported a discussion of HRT. In bivariable analysis, patients of white race were more likely to report a discussion than black patients (72% versus 43%, odds ratio [OR] 3.6, 95% confidence interval [CI] 1.3-9.7). After adjustment for history of osteoporosis and age, white patients were more likely to report a discussion (adjusted OR 3.3, 95% CI 1.1-9.8). Further adjustment for the presence of 2 or more cardiac risk factors did not change the result. Neither level of education nor family income were significantly associated with HRT discussion. Compared with white women, the African-American women we studied were less likely to discuss HRT with their physicians. Further study is needed to determine whether the failure to discuss HRT is due to failure to initiate a discussion on the part of patients, physicians, or both.

Abstract
OBJECTIVES Primary care for people with disabilities often concentrates on underlying debilitating disorders to the exclusion of preventive health concerns. This study examined use of screening and preventive services among adults with mobility problems (difficulty walking, climbing stairs, or standing for extended periods). METHODS The responses of non-institutionalized adults to the 1994 National Health Interview Survey, including the disability and Healthy People 2000 supplements, were analyzed. Multivariable logistic regressions predicted service use on the basis of mobility level, demographic characteristics, and indicators of health care access. RESULTS Ten percent of the sample reported some mobility impairment; 3% experienced major problems. People with mobility problems were as likely as others to receive pneumonia and influenza immunizations but were less likely to receive other services. Adjusted odds ratios for women with major mobility difficulties were 0.6 (95% confidence interval [CI] = 0.4, 0.9) for the Papanicolaou test and 0.7 (95% CI = 0.5, 0.9) for mammography. CONCLUSIONS More attention should be paid to screening and preventive services for people with mobility difficulties. Shortened appointment times, physically inaccessible care sites, and inadequate equipment could further compromise preventive care for this population.

Abstract
BACKGROUND Compared with thinner women, obese women have higher mortality rates for breast and cervical cancer. In addition, obesity leads to adverse social and psychological consequences. Whether obesity limits access to screening for breast and cervical cancer is unclear. OBJECTIVE To examine the relation between obesity and screening with Papanicolaou (Pap) smears and mammography. DESIGN Population-based survey. SETTING United States. PARTICIPANTS 11 435 women who responded to the "Year 2000 Supplement" of the 1994 National Health Interview Survey. MEASUREMENTS Screening with Pap smears and mammography was assessed by questionnaire. RESULTS In women 18 to 75 years of age who had not previously undergone hysterectomy (n = 8394), fewer overweight women (78%) and obese women (78%) than normal-weight women (84%) had had Pap smears in the previous 3 years (P < 0.001). After adjustment for sociodemographic information, insurance and access to care, illness burden, and provider specialty, rate differences for screening with Pap smears were still seen among overweight (-3.5% [95% CI, -5.9% to -1.1%]) and obese women (-5.3% [CI, -8.0% to -2.6%]). In women 50 to 75 years of age (n = 3502), fewer overweight women (64%) and obese women (62%) than normal-weight women (68%) had had mammography in the previous 2 years (P < 0.002). After adjustment, rate differences were -2.8% (CI, -6.7% to 0.9%) for overweight women and -5.4% (CI, -10.8% to -0.1%) for obese women. CONCLUSIONS Overweight and obese women were less likely to be screened for cervical and breast cancer with Pap smears and mammography, even after adjustment for other known barriers to care. Because overweight and obese women have higher mortality rates for cervical and breast cancer, they should be targeted for increased screening.

Abstract
OBJECTIVE To characterize the experiences of patients with congestive heart failure (CHF) during their last 6 months of life. DESIGN A retrospective analysis of data from a prospective cohort study. SETTING Five geographically diverse tertiary care academic medical centers. PARTICIPANTS A total of 1404 patients enrolled in the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) with a diagnosis of an acute exacerbation of CHF, of whom 539 patients died within 1 year of their index hospitalization. METHODS Data from interviews with patients or their surrogates were collected and chart abstractions performed at several time points in SUPPORT. To describe progression to death, we constructed four observational windows backward in time, beginning with patients' dates of death and ending with their date of entry into the SUPPORT project or 6 months before death, whichever came first. For each outcome, patients contributed information to all windows for which they had data collected. We describe frequency distributions for each outcome over time and report tests for trend. OUTCOME MEASURES Outcomes examined over time included: percentage of days spent in a hospital; model-based prognostic estimates of 6-month survival; functional status; occurrence of severe physical and emotional symptoms, including pain, depression and anxiety; patients' preferences for care; and the financial impact of patients' illnesses on their families. RESULTS As death approached, patients' prognoses became poorer and illnesses more severe. Median Acute Physiology Scores for hospitalized patients rose from 33 in the interval 6 months to 3 months before death, to 44 within 3 days of death. However, the median model-based estimate of 6-month survival was 54% even within 3 days of death. Number of functional impairments, median depression scores and percent of patients reporting severe pain or dyspnea increased as death approached, with 41% of patient surrogates reporting that the patient was in severe pain and 63% reporting that the patient was severely short of breath during the 3 days before death. Perceived quality of life did not change appreciably, with 29 to 58 % of patients reporting good to excellent quality of life in all intervals before death. As death approached, patients were more likely to prefer Do Not Resuscitate (DNR) status, with the percent of patients preferring DNR rising from 33% at 6 months to 3 months before death to 47% at 1 month to 3 days before death (P < .05). The frequency with which DNR orders were written for hospitalized patients also increased as death approached. The patients' illnesses had marked financial impact on their families, with 23 % of patients' families reporting the loss of most or all of family savings at the time of the patient's death. CONCLUSIONS As death approaches during the last 6 months of life in CHF, illness becomes more severe, disability and the experience of certain symptoms more frequent, and patient preference not to be resuscitated more common. However, there is no significant decrement in quality of life as death approaches. Reflecting the unpredictable course of CHF during the last month of life, many patients have good median model-based 6-month prognoses and enjoy good to excellent quality of life.

Abstract
PURPOSE Often, it seems that the patient history provided by the referring clinician on the sonography requisition form differs from that given by the patient during the sonographic examination. Because such a discrepancy in the history may delay the scan and disrupt the daily work flow while the referring clinician is contacted for clarification, we sought to document the incidence and cause of such discrepancies at our institution. METHODS During a 3-month period, all outpatients who were referred for a pelvic sonographic examination were asked to indicate their understanding of why the examination had been requested. The health care providers' reasons for requesting sonography were recorded using a computer order entry system. Each pair of responses (health care provider and patient) were classified as either concordant or discordant. Patient and physician characteristics were fit into a logistic regression model with concordance of history as the outcome variable. RESULTS One hundred fifty-six (90%) of the 173 patients enrolled in our study indicated that their health care provider had discussed with them the reason for ordering the sonographic examination. The histories provided by the patient and health care provider were concordant in 134 (77%) of 173 cases. The histories provided by the patient and health care provider were more likely to be concordant if the patient's insurance was a managed care plan or if the patient had a college or graduate level education, had been cared for by the same health care provider for more than 2 years, or had been seen by a female health care provider. Concordance of history was not associated with a higher incidence of abnormal sonographic findings. CONCLUSIONS It appears that health care providers, despite increased demands on their time, adequately discuss with their patients the reasons for ordering a pelvic sonographic examination. However, our study suggests that health care providers may need to spend additional time with patients whose education is limited and that male physicians may need to pay particular attention to their communication with female patients.

Abstract
BACKGROUND A vascular task force (VTF) consisting of two vascular surgeons and other key personnel was established to reduce costs and improve efficiency in the management of patients on a vascular surgery service. METHODS The VTF met monthly beginning in 1994 to study and implement changes in the management of patients with (1) abdominal vascular, (2), carotid endarterectomy (3) distal bypass, and (4) other vascular procedures, including amputations. Length of stay, and fixed and variable costs were assessed for change over time using Pearson correlation coefficients. RESULTS Improvements in efficiency (length of stay) and decreases in costs (fixed and variable costs) from fiscal year 1993 to fiscal year 1996 were significant for the total group of vascular patients (P </=0.001), with some intergroup differences. The major improvements were in the abdominal vascular and carotid endarterectomy groups, where length of stay and fixed and variable costs were reduced significantly (P </=0.01). Management of distal bypass and other vascular surgery patients showed less striking improvement. CONCLUSION Vascular surgeons in collaboration with other dedicated personnel involved in the care of vascular patients can improve efficiency and reduce costs. Advances were greatest in patients who required operations for carotid and abdominal vascular disorders and least for patients who required distal bypasses and other vascular procedures.
