Mistrust, misperceptions, and miscommunication: a qualitative study of preferences about kidney transplantation among African Americans.

BACKGROUND: Kidney transplantation rates in the United States are lower among African Americans than among whites. Well-documented racial disparities in access to transplantation explain some, but not all, of these differences. Prior survey-based research suggests that African American dialysis patients are less likely than whites to desire transplantation, but little research has focused on an in-depth exploration of preferences about kidney transplantation among African Americans. Thus, the purposes of this study were to explore preferences and to compare patients' expectations about transplantation with actual status on the transplant list. METHODS: We conducted semistructured interviews with 16 African Americans receiving chronic hemodialysis. We analyzed the interviews using the constant comparative method of qualitative analysis. We also reviewed the dialysis center's transplant list. RESULTS: Four dominant themes emerged: (1) varied desire for transplant; (2) concerns about donor source; (3) barriers to transplantation; and (4) lack of communication with nephrologists and the transplantation team. A thread of mistrust about equity in the transplantation process flowed through themes 2-4. In 7/16 cases, patients' understanding of their transplant listing status was discordant with their actual status. CONCLUSIONS: Our study suggests that many African Americans on hemodialysis are interested in kidney transplantation, but that interest is often tempered by concerns about transplantation, including misconceptions about the risks to recipients and donors. Mistrust about equity in the organ allocation process also contributed to ambivalence. The discordance between patients' perceptions of listing status and actual status suggests communication gaps between African American hemodialysis patients and physicians. Clinicians should avoid interpreting ambivalence about transplantation as lack of interest.

Combined alpha/beta-blockade versus beta 1-selective blockade in essential hypertension in black and white patients.

The purpose of this multicenter investigation was to determine the efficacy and safety of the alpha/beta-blocker labetalol versus the beta 1-selective beta-blocker atenolol in white and black patients with essential hypertension. Equal numbers of black and white patients were enlisted to form four treatment groups (white patients taking either labetalol or atenolol and black patients taking either labetalol or atenolol). Two hundred ninety-two patients (152 white and 140 black patients) with essential hypertension characterized by a standing diastolic blood pressure of 105 to 119 mm Hg (inclusive) were recruited for this trial. Patients were randomized to either labetalol (dosage titrated from 200 to 1600 mg/day) or atenolol (dosage titrated from 50 to 100 mg/day). The therapeutic goal was achievement of a standing diastolic blood pressure of 90 mm Hg or less or a fall of 15 mm Hg in diastolic pressure from baseline value at the end of the placebo run in period. At the end of the study there were no significant differences in blood pressure or heart rate changes in the supine position between the labetalol and atenolol groups. In contrast, labetalol produced greater reduction in both the standing systolic and diastolic blood pressure (-12/-13 mm Hg, respectively) compared with atenolol (-7/-9 mm Hg; p less than 0.05; p less than 0.005, respectively). The greatest decrease in blood pressure was observed in white patients receiving labetalol. In black patients the decrease in blood pressure was greater in those treated with labetalol compared with atenolol, particularly with respect to the systolic blood pressure. We conclude that the alpha 1-blocking property of labetalol provides an additional lowering of the blood pressure over that seen with beta 1-blockade alone, especially in the standing position, and this enhanced efficacy is not confined to one radical group.

Does the survival advantage of nonwhite dialysis patients persist after case mix adjustment?

PURPOSE: Nonwhite dialysis patients survive longer than white patients; however, their clinical characteristics differ. We examined whether case mix differences explain the apparent survival advantage of nonwhite dialysis patients. SUBJECTS AND METHODS: We performed a prospective cohort study using data from the US Renal Data System Case Mix Severity Study that included 4,797 randomly selected dialysis patients 20 years of age and older who were followed up for up to 6 years. Demographic, comorbidity, laboratory, nutritional, and functional status data were obtained. Multivariable proportional hazards models adjusted for case mix differences between nonwhite and white dialysis patients. Additional analyses examined the effects of differences in transplantation rates, withdrawal from dialysis rates, and treatment modality selection. RESULTS: Unadjusted survival rates of black, Native American, and Asian or Pacific Islander dialysis patients were similar, and better than that for white dialysis patients. Relative to whites, the unadjusted relative risk (RR) for mortality among nonwhite patients was 0.64 (95% confidence interval [CI]: 0.58 to 0.70). Adjustment for case mix reduced, but did not eliminate, the survival advantage associated with nonwhite race (RR = 0.78, CI: 0.71 to 0.86). Adjustment for differences in transplantation rates (RR = 0.83, CI: 0.75 to 0.91), withdrawal from dialysis rates (RR = 0.81, CI: 0.73 to 0.90), and initial treatment modality (RR = 0.79, CI: 0.71 to 0.87) did not explain the lower mortality among nonwhites. CONCLUSIONS: A survival advantage for nonwhite dialysis patients persists after case mix adjustment. Future studies should explore additional physiologic and socioeconomic factors that might explain this difference.

Breast cancer screening for older women in a primary care practice.

OBJECTIVE: To determine rates of breast cancer screening for older women cared for in a primary care practice and to identify associations between patient and physician characteristics and breast cancer screening. STUDY DESIGN: A retrospective cohort study of older women. SETTING: An urban hospital-based academic general medicine practice. This practice uses a computerized medical record and office procedures that facilitate tracking and ordering of mammograms. PARTICIPANTS: A random sample of 130 women aged 65 to 80 who receive primary care at a hospital-based general medicine practice. MEASUREMENTS: Data were collected from the hospital's computerized medical record. We recorded all clinical breast exams and mammograms performed or recommended during the 2-year study period. RESULTS: The median age of the 130 women studied was 71, and 21% of the women were black. Most patients had no serious comorbid illness (69%) and were independent in their activities of daily living (92%). During the 2-year study period, mammography was recommended for 95% of women and completed for 84%, and clinical breast exam was performed on 75%. Patients of male physicians had higher rates of mammography than patients of female physicians (89% vs. 75%, P = .045). Patients of faculty physicians had higher rates of clinical breast exam than patients of house officers or fellows (83% vs. 56%, P = .001). CONCLUSIONS: We report a very high rate of mammography for women cared for at a hospital-based primary care practice. The systems in place to facilitate ordering and tracking of mammograms probably contributed to the unusually high rate of mammography observed.

The last six months of life for patients with congestive heart failure.

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.

Dying with cancer: patients' function, symptoms, and care preferences as death approaches.

OBJECTIVE: To characterize the dying experience of patients with cancer over the last 6 months of life. STUDY DESIGN: A retrospective analysis of the last 6 months of life among patients with colon cancer and non-small cell lung cancer enrolled in a prospective cohort study from June 1989 to June 1991 and from January 1992 to January 1994. SETTING: Five geographically diverse tertiary care academic medical centers participating in the Study to Understand Patient Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT) Project. PARTICIPANTS: All patients enrolled in SUPPORT who had either colon cancer, metastatic to the liver or stage III or stage IV non-small cell lung cancer and died within 1 year of their index hospitalization. This report examines 316 of 520 patients with metastatic colon cancer and 747 of 939 patients with lung cancer enrolled in SUPPORT. METHODS: Data were collected by interview and chart abstraction at several time points in the SUPPORT Project. To describe progression to death, we constructed four observational windows backward in time beginning with patients' date of death and ending with their date of entry into the SUPPORT Project or 6 months before their death, whichever came first: (1) 3 days before death, (2) 3 days to 1 month before death, (3) 1 month to 3 months before death, and (4) 3 months to 6 months before death. For each outcome, patients contributed information to all windows during which they had data collected. We describe the frequency distributions of each outcome over time and report tests for trend. OUTCOME MEASURES: We examined several outcomes over time, including: percentage of days spent in a hospital; prognosis as measured by model-based prognostic estimates of 6-month survival; severity of illness as measured by the acute physiology score; functional status as measured by dependencies in activities of daily living (ADLs); severe physical and emotional symptoms, including pain, depression, and anxiety; patients' preferences for care; and the financial impact on patients' families. RESULTS: The death rate within 1 year of study entry was high among patients with metastatic colon cancer and advanced non-small cell lung cancer enrolled in SUPPORT (61% and 80%, respectively). As patients with cancer progress toward death, their estimated 6-month prognosis decreases significantly and the severity of their disease worsens. Patients' functional status also declines significantly as they approach death, such that most patients have four or more impairments within the 3 days before death. Patients with cancer experience significantly more pain and confusion as death approaches. Severe pain is common; more than one-quarter of patients with cancer experience serious pain 3 to 6 months before death and more than 40% were in serious pain during their last 3 days of life. However, dying patients are only modestly depressed and anxious during their last 3 days of life. As death approaches, patients favor comfort measures over life-extension, and about two-thirds want to forego resuscitation within 3 days of death. Families of patients dying with cancer incurred significant financial burdens during the last 6 months of life, and much of this burden was already experienced by 3 to 6 months before death. CONCLUSIONS: The last 6 months of life for patients with cancer is characterized by functional decline and poorly controlled severe pain and confusion. Although patients increasingly prefer comfort care as they near death, many die in severe pain. These findings highlight important opportunities to improve the quality of care at the end of life for patients dying with cancer.

Outcomes for older men and women with congestive heart failure.

OBJECTIVES: To describe and compare outcomes for men and women discharged alive following a hospitalization for congestive heart failure (CHF). DESIGN: Prospective cohort study. PARTICIPANTS: A total of 519 patients, aged > or = 65, who were discharged alive after a hospitalization for CHF (DRG = 127). MEASUREMENTS: Outcomes (Activities of Daily Living (ADLs), shortness of breath when walking, perceived health, living situation, rehospitalization, and mortality) were measured at 3 times (6 weeks, 6 months, and 1 year) post-discharge. RESULTS: The 205 men were, on average, younger (77 +/- 7 vs 80 +/- 8, P < .001), wealthier (46% vs 21% earned > or = $10,000, P < .001), and more often married (50% vs 19%, P < .001). Men were more likely than women to have a previous history of CHF (71% vs 63%, P = .052). Men also had higher 1-year mortality than women (48% vs 35%, P = .009), even after adjusting for age, comorbidity, physiological severity (APACHE II APS and RAND discharge instability), radiological evidence of CHF, prior ADLs, walking ability, living situation, and perceived health. Men and women survivors at 1-year had similar and substantial impairment for all non-fatal outcomes considered (all P values > or = .489). Their adjusted mean ADL scores were consistent with complete dependence on one essential activity (range 0-6 dependencies); 35% were short of breath walking less than 1 block; 62% had fair or poor perceived health; 32% received some formal care; and 46% were rehospitalized within 1 year of discharge. CONCLUSIONS: Men with CHF have a higher mortality than women with CHF. Men and women who survive have similar and substantial impairment for all non-fatal outcomes (ADLs, shortness of breath upon walking, perceived health, living situation, and rehospitalization).

Living and dying with chronic obstructive pulmonary disease.

OBJECTIVE: To characterize chronic obstructive pulmonary disease (COPD) over patients' last 6 months of life. STUDY DESIGN: A retrospective analysis of a prospective cohort from the Study to Understand Prognoses and Preferences for Outcomes and Risks of Treatments (SUPPORT). SETTING: Hospitalization for exacerbation of COPD at five US teaching hospitals. PARTICIPANTS: COPD patients who died within 1 year (n = 416) among 1016 enrolled. METHODS: Interview and medical record data were organized into time windows beginning with death and ending 6 months earlier. OUTCOME MEASURES: Days in hospital, prognosis, illness severity, function, symptoms, patients' preferences, and impacts on families. RESULTS: One-year survival was 59%, 39% had > or = 3 comorbidities, and 15 to 25% of the patients' last 6 months were in hospitals. Exacerbation etiologies included respiratory infection (47%) and cardiac problems (30%). Better quality of life predicted longer survival (ARR: 0.36; 95% CI, 0.19-0.87) as did heart failure etiology of exacerbation (ARR: 0.57; CI, 0.40, 0.82). Estimates of survival by physicians and by prognostic model were well calibrated, although patients with the worst prognoses survived longer than predicted. Patients' estimates of prognosis were poorly calibrated. One-quarter of patients had serious pain throughout, and two-thirds had serious dyspnea. Patients' illnesses had a major impact on more than 25% of families. Patients' preferences for Do-Not-Resuscitate orders increased from 40% at 3 to 6 months before death to 77% within 1 month of death; their decisions not to use mechanical ventilation increased from 12 to 31%, and their preferences for resuscitation decreased from 52 to 23%. CONCLUSIONS: Patients with advanced COPD often die within 1 year and have substantial comorbidities and symptoms. Adequate description anchors improved care.

Variability in mammography use among older women.

OBJECTIVE: To determine rates of and explore factors associated with mammography use among older women. DESIGN: Retrospective review of part B (physician) bills submitted to Medicare during 1990. SETTING: Health Care Financing Administration (HCFA) data, including sociodemographic information and part B physician bills for all services delivered to Medicare-eligible women in 1990. PATIENTS/PARTICIPANTS: Women age 65 or older as of January 1, 1990, residing in one of 10 states with part B coverage through December 31, 1990. MEASUREMENTS AND MAIN RESULTS: The outcome was receipt of a mammogram (yes/no). We explored factors associated with mammography use within three age groups: 65 to 74, 75 to 84, and 85+. The factors considered were race, state, median income of ZIP Code of residence (from the 1990 US Census, and used to divide the population into quintiles within each state), and number of primary care visits (0, 1, 2, and 3+). Overall, 15% of women had a mammogram: 20% of women age 65 to 74, 12% of women age 75 to 84, and 4% of women age 85 and older. Mammography use was lowest in Oklahoma and highest in Washington. However, in each state the older the age category, the less the mammography use (e.g., 9% vs 5% vs 2% in Oklahoma and 25% vs 16% vs 5% in Washington for women 65-74, 75-84, and 85+, respectively). Mammography use was lower for black than for white women age 65 to 74 (14% vs 21%, P < .001) and 75 to 84 (9% vs 12%, P < .001). Women in each of these two age groups had lower mammography use if they resided in the lowest income quintile and highest if they resided in the highest income quintile (17% vs 23% 65-74, and 10% vs 13% 75-84, P values < .001). Among the oldest women (those 85+), mammography use was low (4%) and varied minimally by race and income (P = .907 and .003, respectively). In all age groups, mammography use was lowest among women who did not have a primary care visit, was greater among women who had at least one visit, and continued to rise with increasing numbers of visits (all P values < .001). For example, among women age 75 to 84, mammography use increased from 5% to 10%, 14%, and 17% for those with 0, 1, 2, and 3+ visits. CONCLUSIONS: We found that mammography use was less for women who were older, of black race, who did not visit a primary care provider, and who lived in areas with lower median income and certain geographic locations (states). Similar factors influenced mammography use in women age 65 to 74, where there is greater consensus as to who should receive a mammogram, and women age 75 to 84, where there is neither consensus nor data. Surprisingly, neither race nor income had much influence on mammography use among women age 85 or older.

Mammography use, breast cancer stage at diagnosis, and survival among older women.

BACKGROUND: Women age 65 years and older account for most newly diagnosed breast cancers and deaths from breast cancer. Yet, older women are least likely to undergo mammography, perhaps because mammography's value is less well demonstrated in older women. OBJECTIVE: To investigate the relationship between prior mammography use, cancer stage at diagnosis, and breast cancer mortality among older women with breast cancer. DESIGN: Retrospective cohort study using the Linked Medicare-Tumor Registry Database. SETTING: Population-based data from three geographic areas included in the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) program. PARTICIPANTS: Women aged 67 and older diagnosed with a first primary breast cancer, from 1987 to 1993, residing in Connecticut, metropolitan Atlanta, Georgia, or Seattle-Puget Sound, Washington. MEASUREMENTS: Medicare claims were reviewed and women were classified according to their mammography use during the 2 years before diagnosis: nonusers (no prior mammograms), regular users (at least two mammograms at least 10 months apart), or peri-diagnosis users (only mammogram(s) within 3 months before diagnosis). Mammography utilization was linked with SEER data to determine stage at diagnosis and cause of death. Our main outcome variables were (1) stage at diagnosis, classified as early (in situ/Stage I) or late (Stage II or greater), and (2) breast cancer mortality, measured from diagnosis until death from breast cancer or end of the follow-up period (December 31, 1994). RESULTS: Older women who were nonusers of mammography were diagnosed with breast cancer at Stage II or greater more often than regular users (adjusted odds ratio (OR), 3.12; 95% confidence interval (CI), 2.74-3.58). This association was present within each age group studied. Nonusers of mammography were at significantly greater risk of dying from their breast cancer than regular users for all women (adjusted hazard ratio (HR), 3.38; 95% CI, 2.65-4.32) and for women within each age group. Even assuming a lead time of 1.25 years, nonusers of mammography continued to be at increased risk of dying from breast cancer. Our findings remained significant for all women and for the two youngest age groups (67-74 years, 75-85 years), although the benefit was no longer statistically significant for the oldest women (85 years and older). CONCLUSIONS: Older women who undergo regular mammography are diagnosed with an earlier stage of disease and are less likely to die from their disease. These data support the use of regular mammography in older women and suggest that mammography can reduce breast cancer mortality in older women, even for women age 85 and older.

How much better can we predict dialysis patient survival using clinical data?

OBJECTIVE: To use three approaches to compare dialysis survival prediction based on variables included in the Standardized Mortality Ratio (SMR) with prediction based on a clinically enriched set of variables. DATA SOURCE: The United States Renal Data System Case Mix Severity data set containing demographic, clinical, functional, nutritional, and treatment details about a random sample of 4,797 adult dialysis patients from 291 treatment units, incident to dialysis in 1986 and 1987. STUDY DESIGN: This observational study uses baseline patient characteristics in two proportional hazards survival models: the BASE model incorporates age, race, sex, and cause of end-stage renal disease (ESRD); the FULL model includes these and additional clinical information. We compare each model's performance using (1) the c-index, (2) observed median survival in strata of predicted risk, and (3) predicted survival for patients with different characteristics. PRINCIPAL FINDINGS: The FULL model's c-index (0.709, 0.708-0.711) is significantly higher than that of the BASE model (0.675, 0.675-0.676), indicating better discrimination. Second, the sickest patients identified by the FULL model were in fact sicker than those identified as sickest by the BASE model, with observed median survival of 451 days versus 524. Third, survival predictions for sickest patients using the FULL model are one-third shorter than those based on the BASE model. CONCLUSIONS: The model with more detailed clinical information predicted survival better than the BASE model. Clinical characteristics enable more accurate predictions, particularly for the sickest patients. Thus, clinical characteristics should be considered when making quality assessments for dialysis patients.

Effect of a hospital nonsmoking policy on patients' knowledge, attitudes, and smoking behavior.

PURPOSE: To explore patients' knowledge of and attitudes toward a hospital nonsmoking policy and to examine changes in patients' smoking behavior before admission and after discharge. DESIGN: Patients were surveyed by mail 1 week after hospitalization. SETTING: A 379-bed Boston tertiary teaching hospital. SUBJECTS: Seven hundred twenty-six patients were surveyed. There were 337 respondents, yielding a response rate of 59%. OUTCOME MEASURES: Policy knowledge, policy satisfaction, and smoking cessation assistance. Smoking status was assessed retrospectively by self-report 1 week before admission and at the time of the survey. RESULTS: Bivariate and multiple logistic regression techniques were used to explore relationships among explanatory variables and outcomes. Knowledge of the policy was fair, although satisfaction with the policy was high. Twenty percent of patients reported that they had quit smoking at the time of the survey; 53% of quitters said they quit because of the policy. Thirty-nine percent of patients reported receiving assistance from medical providers, and 88% were satisfied with this help. Smoking cessation assistance was not associated with quitting but was related to smoking less (p < 0.02). CONCLUSIONS: A hospital nonsmoking policy was well accepted by patients and may have had a favorable impact on patients' smoking behavior. Because intervention by health care providers was limited but appeared to be effective, smoking cessation assistance programs need to be developed and implemented in other hospitals so that these results can be generalizable.

Use of screening and preventive services among women with disabilities.

Roughly 54 million Americans have some disability; at older ages, women are more likely to be disabled than men. Many people with disabilities today live virtually normal life spans, and therefore routine screening and preventive services are essential to their overall quality of care. We used the 1994-1995 National Health Interview Survey (NHIS), with Disability, Family Resources, and Healthy People 2000 supplements, to examine screening and preventive service use for adult women with disabilities living in the community--about 18.4% of women (estimated 18.28 million). Disability was associated with higher age-adjusted rates of: poverty; living alone; low education; inability to work; obesity; and being frequently depressed or anxious. Disabled women generally reported screening and preventive services at rates comparable to all women. Women with major lower extremity mobility difficulties had much lower adjusted odds of Papanicolaou smears (odds ratio, 0.6; 95% confidence interval, 0.4-0.9), mammograms (odds ratio, 0.7; 95% confidence interval, 0.5-0.9), and smoking queries (odds ratio, 0.6; 95% confidence interval, 0.5-0.8). Various approaches exist to improve access for disabled women to health care services.

Postoperative adverse events of cholecystectomy in the Medicare population.

We explored the use of postoperative adverse events of cholecystectomy as possible screens for poor quality of care. Retrospective analysis of clinical data abstracted from hospital charts between 1985-1986 was conducted on a random sample of 3,182 cholecystectomy cases. Severity of illness models were developed predicting adverse events following cholecystectomy in patients with and without bile duct exploration. Outcome measures included 17 nonfatal adverse events and death within 30 days of admission. Adverse event rates were 23.2% for cases with bile duct exploration and 14.4% for cases without bile duct exploration. Cross-validated R-squareds and C-statistics showed that models had real, although modest, predictive power. We conclude that clinically meaningful adverse events of cholecystectomy can be successfully identified through chart abstraction.

Marital status as a predictor of survival in idiopathic dilated cardiomyopathy: the Washington, DC dilated cardiomyopathy study.

Marital status and other socioeconomic and clinical factors were examined as predictors of survival in idiopathic dilated cardiomyopathy using data from a hospital-based study in Washington, DC. Twenty-five (18.1%) of the cases (n = 138) were single, 66 (47.8%) were married, 25 (18.1%) were divorced or separated, and 22 (15.9%) were widowed. Married patients were more likely to be male, to have an annual household income greater than $15,000, and to live with another person (p < or = 0.01) as compared with those who were single, widowed, divorced or separated. Widowed patients were older on average and more likely to abstain from drinking alcohol. The cumulative survival among widowed patients at 12 and 24 months was 54.6 and 48.5%, respectively, as compared with 75.8 and 59.0% among single patients and 80.0 and 71.2% among married patients. The survival of divorced or separated patients was relatively good with a cumulative survival of 84.0% at both 12 and 24 months. Older age, lower ejection fraction, ventricular arrhythmias, bundle branch block, and marital status were significant predictors of survival in univariate analysis using the proportional hazards model. In multivariable analysis, age, race, ejection fraction, and marital status were statistically significant independent predictors of survival, with single patients with idiopathic dilated cardiomyopathy having a poorer survival than those who were married (adjusted RR = 2.5, 95% CI 1.1-6.2, p < 0.05). The observed association with marital status may be explained by psychosocial factors not examined in the present study such as quality of social network or psychological stress.

Screening for cervical and breast cancer: is obesity an unrecognized barrier to preventive care?

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.

Mobility impairments and use of screening and preventive services.

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.

Physician counseling about exercise.

CONTEXT: The increase in sedentary lifestyle may contribute to the rise in obesity nationally. Although guidelines suggest that physicians counsel all patients about exercise, physicians counsel only a minority of their patients. Whether patient factors influence physician counseling is not well established. OBJECTIVES: To examine and to identify factors associated with exercise counseling by US physicians. DESIGN AND SETTING: National population-based supplemental (Year 2000) survey to the 1995 National Health Interview Survey. PARTICIPANTS: Of the 17317 respondents to the Year 2000 supplemental survey, 9711 adults had seen a physician in the previous year, and 9299 responded when asked about physician counseling on exercise. MAIN OUTCOME MEASURE: Physician counseling to begin or to continue to exercise. RESULTS: Of 9299 respondents, 34% reported being counseled about exercise at their last visit. After adjustment for other sociodemographic and clinical factors, women were slightly more likely to be counseled, with an adjusted odds ratio (AOR) of 1.15 (95% confidence interval [CI], 1.02-1.29). Physicians counseled older patients (>30 years) more often than younger patients; those aged 40 to 49 years were counseled most often (AOR, 1.71 [95% CI, 1.34-2.20]). Patients with incomes above $50000, those with higher levels of physical activity, college graduates, and patients who were overweight to obese (body mass index: 25 to > or =30 kg/m2) were more likely to be counseled, as were patients with cardiac disease (AOR, 1.81 [95% CI, 1.52-2.14]) and diabetes (AOR, 1.87 [95% CI, 1.46-2.38]). Counseling did not vary by physician specialty or patient race. CONCLUSION: The rate of physician counseling about exercise is low nationally. Physicians appear to counsel as secondary prevention and are less likely to counsel patients at risk for obesity. The failure to counsel younger, disease-free adults and those from lower socioeconomic groups may represent important missed opportunities for primary prevention.

Prevalence of domestic violence in an inpatient female population.

Studies have evaluated the prevalence of domestic violence in populations of patients in emergency and primary care settings, but there are little data on patients admitted to hospitals. We undertook a study to evaluate the prevalence of domestic violence among female inpatients. Of 131 consecutive female patients between the ages of 18 and 60 admitted to a nontrauma urban teaching hospital asked to complete a self-administered survey about domestic violence, 101 completed the questionnaire. Twenty-six percent of the respondents reported being in an abusive relationship at one time. Two patients felt that domestic violence contributed to their current reason for admission. No respondents were asked about domestic violence by health care providers. Domestic violence is an uncommon but important precipitant to nontrauma hospital admissions. Physicians should query all female inpatients about domestic assault.

Mobility difficulties are not only a problem of old age.

BACKGROUND: Lower extremity mobility difficulties often result from common medical conditions and can disrupt both physical and emotional well-being. OBJECTIVES: To assess the national prevalence of mobility difficulties among noninstitutionalized adults and to examine associations with demographic characteristics and other physical and mental health problems. DESIGN: Cross-sectional survey using the 1994-1995 National Health Interview Survey-Disability Supplement (NHIS-D). We constructed measures of minor, moderate, and major lower extremity mobility difficulties using questions about ability to walk, climb stairs, and stand, and use of mobility aids (e.g., canes, wheelchairs). Age and gender adjustment used direct standardization methods in Software for the Statistical Analysis of Correlated Data (SUDAAN). PARTICIPANTS: Noninstitutionalized, civilian U.S. residents aged 18 years and older. National Health Interview Survey sampling weights with SUDAAN provided nationally representative population estimates. RESULTS: An estimated 19 million people (10.1%) reported some mobility difficulty. The mean age of those with minor, moderate, or major difficulty ranged from 59 to 67 years. Of those reporting major difficulties, 32% said their problems began at aged 50 years or younger. Adjusted problem rates were higher among women (11.8%) than men (8.8%), and higher among African American (15.0%) than whites (10.0%). Persons with mobility difficulties were more likely to be poorly educated, living alone, impoverished, obese, and having problems conducting daily activities. Among persons with major mobility difficulties, 30.6% reported being frequently depressed or anxious, compared to 3.8% for persons without mobility difficulties. CONCLUSIONS: Reports of mobility difficulties are common, including among middle-aged adults. Associations with poor performance of daily activities, depression, anxiety, and poverty highlight the need for comprehensive care for persons with mobility problems.
