Patient-reported service quality on a medicine unit.

PURPOSE: Service quality, defined as patients' self-reported experience of care, is used as a metric for evaluating quality. Most studies rely on retrospective consumer surveys rather then more intensive data collection methods, possibly underestimating the incidence of service quality incidents. SUBJECTS AND METHODS: The objective of the study was to characterize patient-reported service quality deficiencies on a general medicine unit. We studied a cohort of 228 adult inpatients at a Boston teaching hospital. Investigators reviewed medical records and interviewed patients during the hospitalization and by telephone after discharge. Physician investigators classified patients' incident reports. We calculated the rate of service incidents, characterized incident types, and used multivariable Poisson and logistic regression models to examine factors associated with patient reporting and overall rating of the hospitalization. RESULTS: Eighty-eight (38.6%) of 228 patients experienced 157 service quality incidents during the admission, for a rate of 68.9 incidents per 100 admissions. The most common service quality problems involved waits and delays (n = 45), problems with communication between staff and patients (n = 36), and environmental issues and amenities (n = 35). In the multivariable analysis, men (IRR 1.6, 95% CI 1.1-2.2), patients covered by hospitalists (1.5, 1.1-2.2), and patients with more medication allergies (1.1 per allergy, 1.1-1.2) reported more service incidents; patients with Medicaid or free care reported fewer (0.5, 0.3-0.9). Patients with service quality incidents were more likely to describe the hospitalization as other than excellent (adjusted OR 1.8 per incident, 95% CI 1.3-2.5). CONCLUSION: Service quality deficiencies are common among medical inpatients, and are strongly associated with patients' dissatisfaction with the hospitalization.

Emerging credentialing practices, malpractice liability policies, and guidelines governing complementary and alternative medical practices and dietary supplement recommendations: a descriptive study of 19 integrative health care centers in the United States.

BACKGROUND: Little is known about policies governing the integration of complementary and alternative medical (CAM) therapies and providers. METHODS: To document emerging approaches in 19 US hospitals regarding credentialing, malpractice liability, and pharmacy policies governing integration of CAM therapies and providers into conventional medical settings, we surveyed 21 academic medical centers and 13 non-academically affiliated hospitals that are nationally visible and are integrating CAM therapies into conventional medical settings. Of the 19 respondents, 11 were tertiary care hospitals, 6 were community hospitals, 1 was a freestanding center associated with a community-based hospital, and 1 was a university-based rehabilitation hospital. RESULTS: Institutions had no consistent approach to provider mix and authority within the integrative care team, and minimum requirements for professional liability insurance, informed consent disclosure, and hiring status. Less than a third had a formal (stated) policy concerning dietary supplements; those selling supplements in their pharmacy lacked consistent, evidence-based rationales regarding which products and brands to include or exclude. Although many hospitals confiscated patient supplements on admission, institutions had inconsistent criteria regarding allowance of home supply. CONCLUSIONS: Hospitals are using heterogeneous approaches to address licensure, credentialing, scope of practice, malpractice liability, and dietary supplement use in developing models of integrative care. The environment creates significant impediments to the delivery of consistent clinical care and multisite evaluations of the safety, efficacy, and cost-effectiveness (or lack thereof) of CAM therapies (or integrative models) as applied to management of common medical conditions. Consensus policies need to be developed.

Association between completeness of percutaneous coronary revascularization and postprocedure outcomes.

BACKGROUND: Multivessel coronary artery revascularization may be accomplished by percutaneous coronary intervention (PCI) or coronary artery bypass graft surgery (CABG). The importance of complete revascularization is emphasized in the surgical literature, but little is known about its impact on PCI outcomes. This study evaluated multivessel PCI patients to determine the predictors of complete revascularization and the association of complete revascularization with survival, subsequent CABG, and repeat PCI. METHODS: The Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) is a clinical data collection and outcome-monitoring initiative capturing all patients undergoing cardiac catheterization and revascularization in the province of Alberta, Canada. Characteristics and long-term outcomes of 1308 patients undergoing multivessel PCI with complete revascularization were compared with those of 648 patients with incomplete revascularization. RESULTS: The significant independent predictors of complete revascularization were pre-PCI Duke jeopardy score, the presence of a total occlusion, year of PCI, age > 65 years, renal failure, and left ventricular function. With a median follow-up time of 3.0 +/- 1.8 years, the adjusted hazard ratio (HR) (95% CI) for the association between complete revascularization and outcome was 0.75 (0.54-1.04) for death, 0.55 (0.37-0.84) for subsequent CABG, and 0.93 (0.65-1.34) for repeat PCI. CONCLUSIONS: Baseline angiographic characteristics and other clinical factors can predict complete revascularization in patients undergoing multivessel PCI. Complete multivessel PCI is associated with reduced need for future CABG, a trend toward better survival, and no difference in repeat PCI.

Factors associated with the use of mind body therapies among United States adults with musculoskeletal pain.

OBJECTIVE: To determine the prevalence of mind body therapy use and correlates of use among adults with prolonged musculoskeletal pain, a group for whom mind body therapies are recommended. DESIGN: The U.S. 1999 National Health Interview Survey. Prolonged musculoskeletal pain was defined as any soft tissue, joint, or bony pain for at least 1 month. Analyses used SUDAAN and reflect national estimates. MAIN OUTCOME MEASURES: Use of mind body medicine (relaxation techniques, imagery, biofeedback, and hypnosis) and prayer in the previous year. RESULTS: Respondents (n=6079) with musculoskeletal pain were almost twice as likely as those without (n=24,722) to use mind body medicine (9% versus 5%, respectively, p<.0001) and prayer (20% versus 12%, respectively, p<.0001). After adjustment, men were less likely than women to use mind body medicine (odds ratio 0.55 [0.43-0.71]) and prayer (odds ratio 0.56 [0.48-0.66]). Those who had a high school education were less likely than those with training beyond high school to use mind body medicine (odds ratio 0.36 [0.28-0.47]) and prayer (odds ratio 0.61 [0.52-0.71]). CONCLUSIONS: Mind body therapies are not used commonly by adults with prolonged musculoskeletal pain. Understanding barriers to their use may facilitate wider application in this population.

A comprehensive new curriculum to teach and assess resident knowledge and diagnostic evaluation of musculoskeletal complaints.

Musculoskeletal complaints are a common reason for primary care visits; however, many essential physical examination, diagnostic and treatment skills are not adequately taught. The objectives of the study were to create and implement a comprehensive clinical skills teaching model, and to evaluate its effects on residents' knowledge and diagnostic skills. A comparison of cohorts who participated and did not participate in a musculoskeletal curriculum was undertaken. Second and third year medical residents participated in comprehensive curricula to teach and evaluate musculoskeletal skills. Sixty-seven attended the first of three lectures on the painful shoulder; 61 attended all three lectures and completed pre- and post-self assessment forms and tests. Three months later 26 of these residents and 10 controls participated in an OSCE examination. Thirty-nine medical residents attended the first of three lectures on the painful knee; 32 attended all three lectures and completed pre- and post-self assessment forms and tests. Seven of these residents and eight controls participated in an OSCE examination three months later. Both the shoulder and knee curricula were associated with a significant improvement in test scores (p < 0.0001), in self-assessment of physical examination, diagnostic and procedural skills (p < 0.0001), and in OSCE results (p < 0.005). It was concluded that the skills required for the diagnosis and treatment of common musculoskeletal complaints can be effectively taught and assessed using inexpensive and simple methods.

Pharmacy-and diagnosis-based risk adjustment for children with Medicaid.

BACKGROUND: Risk adjustment is useful for adjusting health care payments based on patients' health status. OBJECTIVE: This work seeks to examine how well pharmacy- and diagnosis-based risk adjusters predict child health expenditures in Medicaid populations. RESEARCH DESIGN: We used 1994-1995 Medicaid claims files for all children ages 0-18 years who were not covered by managed care in 3 states: Georgia, New Jersey, and Wisconsin. We examined separately 6 risk adjustment methods, 2 pharmacy-based and 4 diagnosis-based. We compared predictive accuracy of the methods for the whole sample and stratified by state and Medicaid enrollment category. FINDINGS: Models with risk adjustment (either diagnosis- or pharmacy-based) had better predictive accuracy than demographic models. The pharmacy and diagnosis-based models had similar predictive accuracy. Risk adjuster performance differed by Medicaid enrollment category and state. Risk-adjusted models generally underpredict expenditures in populations with worse health status (eg, those in the Supplemental Security Income program [SSI]). The pharmacy-based models performed well for children in SSI relative to children in foster care. CONCLUSIONS: Both pharmacy- and diagnosis-based risk adjustment improved the prediction of health expenditures compared models without risk adjustment. No single risk adjuster performed best in all situations, suggesting that optimal choices of risk adjusters may differ by purpose and context.

Stage of readiness to control weight and adopt weight control behaviors in primary care.

BACKGROUND: While the majority of adults are attempting weight loss at any given time, few engage in optimal diet and exercise. We examined factors associated with being in advanced stages of behavior change for weight loss, diet, and exercise. METHODS: We surveyed primary care patients about their health, health habits, and perception and advice about weight as health risk, and about stage of readiness to lose weight, improve diet (control food portions, limit fat intake, increase fruits and vegetables), and increase planned exercise using the Prochaska Stage of Behavior Change model. We conducted bivariable analyses to describe the association between being at the preparation (change in 1 month), action (changing now), and maintenance (maintaining change) stages of change for weight loss and being at 1 of these 3 advanced stages for improving diet and exercise. We also conducted multivariable analyses to examine factors associated with being at these advanced stages of readiness to concurrently lose weight, improve diet, and increase exercise. RESULTS: Of 365 patients (response rate of 60%), 33% were overweight (body mass index [BMI], 25.0-29.9 kg/m(2)) and 27% were obese (BMI, 30.0+kg/m(2)). Of 199 respondents at the preparation, action, or maintenance stage of losing weight, 61% were also at an advanced stage for improving diet and exercise. Those perceiving weight as a health risk were more likely to be at advanced stages of readiness to concurrently lose weight, improve diet, and increase exercise (adjusted odds ratio [AOR], 5.6; 95% CI, 2.5 to 12.5) after adjustment for confounders; this perception was associated with BMI ([AOR, 1.2; 95% CI, 1.1 to 1.3 for each unit increment in BMI]) and being advised by a physician about weight as a health risk (AOR, 6.7; 95% CI, 3.0 to 15.1). Demographic factors, having obesity-related comorbidities, and mental and physical functioning did not appear important. CONCLUSIONS: A large proportion of primary care patients are at advanced stages of readiness to lose weight, improve diet, and increase exercise. Future studies should examine the effectiveness of primary care interventions to help patients optimize weight-related behavior.

Trends in breast conserving surgery among Asian Americans and Pacific Islanders, 1992-2000.

BACKGROUND: Breast-conserving surgery (BCS) has been the recommended treatment for early-stage breast cancer since 1990 yet many women still do not receive this procedure. OBJECTIVE: To examine the relationship between birthplace and use of BCS in Asian-American and Pacific-Islander (AAPI) women, and to determine whether disparities between white and AAPI women persist over time. DESIGN: Retrospective cohort study. SETTING AND PARTICIPANTS: Women with newly diagnosed stage I or II breast cancer from 1992 to 2000 in the Surveillance, Epidemiology, and End Results program. OUTCOME: Receipt of breast -conserving surgery for initial treatment of stage I or II breast cancer. MAIN RESULTS: Overall, AAPI women had lower rates of BCS than white women (47% vs 59%; P<.01). Foreign-born AAPI women had lower rates of BCS than U.S.-born AAPI and white women (43% vs 56% vs 59%; P<.01). After adjustment for age, marital status, tumor registry, year of diagnosis, stage at diagnosis, tumor size, histology, grade, and hormone receptor status, foreign-born AAPI women (adjusted OR [aOR], 0.49; 95% CI, 0.32 to 0.76) and U.S.-born AAPI women (aOR, 0.77; 95% CI, 0.62 to 0.95) had lower odds of receiving BCS than white women. Use of BCS increased over time for each racial/ethnic group; however, foreign-born AAPI women had persistently lower rates of BCS than non-Hispanic white women. CONCLUSIONS: AAPI women, especially those who are foreign born, are less likely to receive BCS than non-Hispanic white women. Of particular concern, differences in BCS use among foreign-born and U.S.-born AAPI women and non-Hispanic white women have persisted over time. These differences may reflect inequities in the treatment of early-stage breast cancer for AAPI women, particularly those born abroad.

What can hospitalized patients tell us about adverse events? Learning from patient-reported incidents.

PURPOSE: Little is known about how well hospitalized patients can identify errors or injuries in their care. Accordingly, the purpose of this study was to elicit incident reports from hospital inpatients in order to identify and characterize adverse events and near-miss errors. SUBJECTS: We conducted a prospective cohort study of 228 adult inpatients on a medicine unit of a Boston teaching hospital. METHODS: Investigators reviewed medical records and interviewed patients during the hospitalization and by telephone 10 days after discharge about "problems,""mistakes," and "injuries" that occurred. Physician investigators classified patients' reports. We calculated event rates and used multivariable Poisson regression models to examine the factors associated with patient-reported events. RESULTS: Of 264 eligible patients, 228 (86%) agreed to participate and completed 528 interviews. Seventeen patients (8%) experienced 20 adverse events; 1 was serious. Eight patients (4%) experienced 13 near misses; 5 were serious or life threatening. Eleven (55%) of 20 adverse events and 4 (31%) of 13 near misses were documented in the medical record, but none were found in the hospital incident reporting system. Patients with 3 or more drug allergies were more likely to report errors compared with patients without drug allergies (incidence rate ratio 4.7, 95% CI 1.7, 13.4). CONCLUSION: Inpatients can identify adverse events affecting their care. Many patient-identified events are not captured by the hospital incident reporting system or recorded in the medical record. Engaging hospitalized patients as partners in identifying medical errors and injuries is a potentially promising approach for enhancing patient safety.

Health care expenditures associated with overweight and obesity among US adults: importance of age and race.

OBJECTIVES: We estimated health care expenditures associated with overweight and obesity and examined the influence of age, race, and gender. METHODS: Using 1998 Medical Expenditure Panel Survey data, we employed 2-stage modeling to estimate annual health care expenditures associated with high body mass index (BMI) and examine interactions between demographic factors and BMI. RESULTS: Overall, the mean per capita annual health care expenditure (converted to December 2003 dollars) was $3338 before adjustment. While the adjusted expenditure was $2127 (90% confidence interval [CI]=$1927, $2362) for a typical normal-weight White woman aged 35 to 44 years, expenditures were $2358 (90% CI=$2128, $2604) for women with BMIs of 25 to 29.9 kg/m(2), $2873 (90% CI=$2530, $3236) for women with BMIs of 30 to 34.9 kg/m(2), $3058 (90% CI=$2529, $3630) for women with BMIs of 35 to 39.9 kg/m(2), and $3506 (90% CI=$2912, $4228) for women with BMIs of 40 kg/m(2) or higher. Expenditures related to higher BMI rose dramatically among White and older adults but not among Blacks or those younger than 35 years. We found no interaction between BMI and gender. CONCLUSIONS: Health care costs associated with overweight and obesity are substantial and vary according to race and age.

Use of complementary and alternative medical therapies among racial and ethnic minority adults: results from the 2002 National Health Interview Survey.

PURPOSE: Complementary and alternative medicine (CAM) use among ethnic minority populations is poorly understood. We sought to examine CAM use in Hispanics, non-Hispanic blacks and non-Hispanic whites. METHODS: We analyzed data from the Alternative Health Supplement to the 2002 National Health Interview Survey (NHIS), including information on 19 different CAM therapies used in the past 12 months. RESULTS: An estimated 34% of Hispanic, non-Hispanic black and non-Hispanic white adults in the United States used at least one CAM therapy (excluding prayer) during the prior 12 months (2002). CAM use was highest for non-Hispanic whites (36%), followed by Hispanics (27%) and non-Hispanic blacks (26%). Non-Hispanic whites were more likely to use herbal medicine, relaxation techniques and chiropractic more frequently than Hispanics and non-Hispanic blacks. After controlling for other sociodemographic factors, Hispanic and non-Hispanic black races/ethnicities were associated with less CAM use, with adjusted odds ratios (95% confidence intervals) of 0.78 (0.70, 0.87) and 0.71 (0.65, 0.78), respectively. Hispanics cited using CAM because conventional medical treatments were too expensive more frequently than non-Hispanic blacks or whites. Hispanics had the highest provider nondisclosure rates (68.5%), followed by non-Hispanic blacks (65.1%) and non-Hispanic whites (58.1%). CONCLUSIONS: Excluding prayer, Hispanics and non-Hispanic blacks used CAM less frequently than non-Hispanic whites and were less likely to disclose their use to their healthcare provider. Further research is needed to improve our understanding of the disparities in CAM use.

Heavy metal content of ayurvedic herbal medicine products.

CONTEXT: Lead, mercury, and arsenic intoxication have been associated with the use of Ayurvedic herbal medicine product (HMPs). OBJECTIVES: To determine the prevalence and concentration of heavy metals in Ayurvedic HMPs manufactured in South Asia and sold in Boston-area stores and to compare estimated daily metal ingestion with regulatory standards. DESIGN AND SETTING: Systematic search strategy to identify all stores 20 miles or less from Boston City Hall that sold Ayurvedic HMPs from South Asia by searching online Yellow Pages using the categories markets, supermarkets, and convenience stores, and business names containing the word India, Indian cities, and Indian words. An online national directory of Indian grocery stores, a South Asian community business directory, and a newspaper were also searched. We visited each store and purchased all unique Ayurvedic HMPs between April 25 and October 24, 2003. MAIN OUTCOME MEASURES: Concentrations (microg/g) of lead, mercury, and arsenic in each HMP as measured by x-ray fluorescence spectroscopy. Estimates of daily metal ingestion for adults and children estimated using manufacturers' dosage recommendations with comparisons to US Pharmacopeia and US Environmental Protection Agency regulatory standards. RESULTS: A total of 14 (20%) of 70 HMPs (95% confidence interval, 11%-31%) contained heavy metals: lead (n = 13; median concentration, 40 microg/g; range, 5-37,000), mercury (n = 6; median concentration, 20,225 microg/g; range, 28-104,000), and/or arsenic (n = 6; median concentration, 430 microg/g; range, 37-8130). If taken as recommended by the manufacturers, each of these 14 could result in heavy metal intakes above published regulatory standards. CONCLUSIONS: One of 5 Ayurvedic HMPs produced in South Asia and available in Boston South Asian grocery stores contains potentially harmful levels of lead, mercury, and/or arsenic. Users of Ayurvedic medicine may be at risk for heavy metal toxicity, and testing of Ayurvedic HMPs for toxic heavy metals should be mandatory.

Effects of tai chi mind-body movement therapy on functional status and exercise capacity in patients with chronic heart failure: a randomized controlled trial.

PURPOSE: To examine the effects of a 12-week tai chi program on quality of life and exercise capacity in patients with heart failure. METHODS: Thirty patients with chronic stable heart failure and left ventricular ejection fraction < or =40% (mean [+/- SD] age, 64 +/- 13 years; mean baseline ejection fraction, 23% +/- 7%; median New York Heart Association class, 2 [range, 1 to 4]) were randomly assigned to receive usual care (n = 15), which included pharmacologic therapy and dietary and exercise counseling, or 12 weeks of tai chi training (n = 15) in addition to usual care. Tai chi training consisted of a 1-hour class held twice weekly. Primary outcomes included quality of life and exercise capacity. Secondary outcomes included serum B-type natriuretic peptide and plasma catecholamine levels. For 3 control patients with missing data items at 12 weeks, previous values were carried forward. RESULTS: At 12 weeks, patients in the tai chi group showed improved quality-of-life scores (mean between-group difference in change, -25 points, P = 0.001), increased distance walked in 6 minutes (135 meters, P = 0.001), and decreased serum B-type natriuretic peptide levels (-138 pg/mL, P = 0.03) compared with patients in the control group. A trend towards improvement was seen in peak oxygen uptake. No differences were detected in catecholamine levels. CONCLUSION: Tai chi may be a beneficial adjunctive treatment that enhances quality of life and functional capacity in patients with chronic heart failure who are already receiving standard medical therapy.

Complementary and alternative medical therapies for chronic low back pain: What treatments are patients willing to try?

BACKGROUND: Although back pain is the most common reason patients use complementary and alternative medical (CAM) therapies, little is known about the willingness of primary care back pain patients to try these therapies. As part of an effort to refine recruitment strategies for clinical trials, we sought to determine if back pain patients are willing to try acupuncture, chiropractic, massage, meditation, and t'ai chi and to learn about their knowledge of, experience with, and perceptions about each of these therapies. METHODS: We identified English-speaking patients with diagnoses consistent with chronic low back pain using automated visit data from one health care organization in Boston and another in Seattle. We were able to confirm the eligibility status (i.e., current low back pain that had lasted at least 3 months) of 70% of the patients with such diagnoses and all eligible respondents were interviewed. RESULTS: Except for chiropractic, knowledge about these therapies was low. Chiropractic and massage had been used by the largest fractions of respondents (54% and 38%, respectively), mostly for back pain (45% and 24%, respectively). Among prior users of specific CAM therapies for back pain, massage was rated most helpful. Users of chiropractic reported treatment-related "significant discomfort, pain or harm" more often (23%) than users of other therapies (5-16%). Respondents expected massage would be most helpful (median of 7 on a 0 to 10 scale) and meditation least helpful (median of 3) in relieving their current pain. Most respondents indicated they would be "very likely" to try acupuncture, massage, or chiropractic for their back pain if they did not have to pay out of pocket and their physician thought it was a reasonable treatment option. CONCLUSIONS: Most patients with chronic back pain in our sample were interested in trying therapeutic options that lie outside the conventional medical spectrum. This highlights the need for additional studies evaluating their effectiveness and suggests that researchers conducting clinical trials of these therapies may not have difficulties recruiting patients.

Breast carcinoma screening and risk perception among women at increased risk for breast carcinoma: results from a national survey.

BACKGROUND: The Gail model is validated to estimate breast carcinoma risk. The authors assessed the association of Gail risk scores with screening and cancer risk perception. METHODS: Using the 2000 National Health Interview Survey, the authors studied women ages 41-70 without a cancer history. Gail scores > or = 1.66% defined increased risk. The authors used logistic regression to assess associations between breast carcinoma risk and previous and recent (< or = 1 year) mammography and clinical breast examination (CBE). RESULTS: Of 6410 women, 15.7% had increased risk. High-risk women more frequently reported previous mammograms (94% vs. 85%; P < 0.0001), previous CBE (93% vs. 88%; P < 0.0001), recent mammograms (70% vs. 54%; P < 0.0001), recent CBE (71% vs. 61%; P < 0.0001), and high cancer risk perception (20% vs. 9%; P < 0.0001). However, 30% of high-risk women had not received a recent mammogram. After adjustment for sociodemographic factors, access to care factors, and cancer risk perception, high-risk women remained more likely to have received recent mammography (adjusted odds ratio [OR], 1.45, 95% confidence interval [95% CI], 1.19-1.77), recent CBE (OR, 1.32; 95% CI, 1.08-1.61]), and previous mammography than average-risk women. The authors observed an interaction between risk and age, with women ages 41-49 years more frequently reporting previous mammography (OR, 4.79; 95% CI, 1.55-4.81) than average-risk, same-age women. For women age > or = 50 years, the odds of previous mammography were similar regardless of risk. CONCLUSIONS: In a nationally representative sample, 15.7% of women had increased breast carcinoma risk using the Gail model. High-risk women perceived higher cancer risk and more often received screening. However, nearly one in three high-risk women did not receive recent screening and most of these women did not perceive increased risk.

Prayer for health concerns: results of a national survey on prevalence and patterns of use.

BACKGROUND: Prayer is a common practice in the United States, yet little is known about the prevalence and patterns of use of prayer for health concerns. OBJECTIVE: To determine the prevalence and patterns of use of prayer for health concerns. METHODS: We conducted a national survey in 1998 (N = 2055, 60% weighted response rate) on use of prayer. Data were also collected on sociodemographics, use of conventional medicine, and use of complementary and alternative medical therapies. Factors associated with the use of prayer were analyzed using multivariable logistic regression. RESULTS: We found that 35% of respondents used prayer for health concerns; 75% of these prayed for wellness, and 22% prayed for specific medical conditions. Of those praying for specific medical conditions, 69% found prayer very helpful. Factors independently associated with increased use of prayer (P<.05) included age older than 33 years (age 34-53 years: odds ratio [OR], 1.6 [95% confidence interval (CI), 1.3-2.1]; age > or =54 years: OR, 1.5 [95% CI, 1.1-2.0]); female sex (OR, 1.4 [95% CI, 1.1-1.7]); education beyond high school (OR, 1.5 [95% CI, 1.2-1.8]); and having depression, chronic headaches, back and/or neck pain, digestive problems, or allergies. Only 11% of respondents using prayer discussed it with their physicians. CONCLUSIONS: An estimated one third of adults used prayer for health concerns in 1998. Most respondents did not discuss prayer with their physicians. Prayer was used frequently for common medical conditions, and users reported high levels of perceived helpfulness.

Using a multihospital survey to examine the safety culture.

BACKGROUND: A culture of safety survey was used to study features of the safety culture and their relationship with patient safety indicators. STUDY DESIGN: Anonymous written surveys were collected from 455 of 1,027 (44%) workers at four Massachusetts hospitals. Respondents characterized their organizations' patient safety, workplace safety, and features of a safety culture, such as leadership commitment, professional salience, presence of a nonpunitive environment, error reporting, and communication. RESULTS: Employees universally regarded patient safety as an essential part of their job. Two-thirds of workers worried at least once a day about making a mistake that could injure a patient; 43% said that the work load hindered their ability to keep patients safe. Workers' overall assessment of patient safety was associated with their perceptions of workplace safety (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.02-3.43, p = .044) and leadership commitment to patient safety (OR 3.20, 95% CI 1.97-5.19, p < .001). Incident reporting rates correlated with survey results, while adoption of best practices and expert opinion did not. DISCUSSION: Patient safety is salient to workers, who universally embraced patient safety as an essential part of their job. Independent indicators of patient safety did not line up neatly with safety culture survey results. Incident reporting rates correlated directly, while adoption of best practices and expert opinion varied inversely with survey results. The safety culture is a complex phenomenon that requires further study.

A comparison of endometrial cancer outcomes in Ontario.

OBJECTIVE: To compare endometrial cancer treatment strategies and outcomes across the province of Ontario, Canada. METHODS: A retrospective cohort study was conducted of 195 women diagnosed with endometrial cancer in Ontario between 1996 and 1998, as a sample of the population. The women's charts were randomly selected by the medical records departments at 5 tertiary care centres in Ontario. The outcomes measured included 5-year overall survival (OS) and disease-free survival (DFS), use of adjuvant radiotherapy, treatment complications, and prognostic factors for survival. RESULTS: The 2 main treatment strategies were (1) total abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH BSO) and (2) surgical staging (defined as TAH BSO and pelvic lymph node dissection with or without cytology, peritoneal biopsies, and omentectomy). Surgical staging rates across the province ranged from 0% to 88%. Stratified survival analysis revealed a significant difference in OS among centres (log rank P =.039). Crude survival analysis revealed no difference in 5-year OS or DFS between the 2 treatment strategies. The Cox proportional hazards model identified advanced stage of tumour as being the most predictive factor of DFS, and the woman's age at diagnosis and tumour grade as predictive of OS. DISCUSSION: There was a significant difference in 5-year OS among the 5 tertiary care centres. There was no significant difference between surgical staging and TAH BSO with respect to 5-year DFS or OS. CONCLUSION: As there were significant differences in the treatment of endometrial carcinoma and OS across the province, a population-based study of endometrial cancer treatment strategies and outcomes is required.
