Factors associated with older patients' satisfaction with care in an inner-city emergency department.

STUDY OBJECTIVES: We sought to assess older patients' satisfaction with care in the emergency department and to identify factors associated with global satisfaction with care. METHODS: We performed a prospective cohort study of 778 patients 65 years of age and older presenting to an urban academic ED between 1995 and 1996, of whom 79% were black and 63% were female. A baseline survey at presentation to the ED asked for demographic information, medical history, and health-related quality of life information. A follow-up satisfaction survey asked patients to rate the care they received in the ED on a 5-point Likert scale (1=excellent, 5=poor). Overall satisfaction with care, dichotomized into responses of "excellent" versus all others, was the primary dependent variable in our bivariate analyses. RESULTS: Of respondents, 40% rated their ED care as "excellent." Variables significantly correlated with high satisfaction include having the perception of time spent in the ED as not "too long," having the emergency physicians and nurses clearly answer patients' questions, having a relationship of trust with an ED staff member, being told why tests were done, feeling involved in decisions about care as much as they wanted, having pain addressed fully, having a perception of greater health status, and having fewer comorbid conditions at the time of the ED visit. Results may be applicable only to urban academic EDs and may be limited by time elapsed between ED visits and follow-up surveys. CONCLUSION: To improve quality of care for older adults in the ED, physicians should be more attentive to older patients' concerns and questions, recognize and aggressively treat pain, and reduce the patients' perception of a long waiting time.

Early revisit, hospitalization, or death among older persons discharged from the ED.

The purpose of this study to determine predictors of revisit, hospital admission, or death among older patients discharged from the emergency department (ED). We performed a prospective study of patients aged 65 or older in an urban ED. The primary outcomes were ED revisit, hospital admission, or death 30 or 90 days after discharge from an index ED visit. Of the 463 eligible patients, 75 (16%) experienced ED revisit, hospitalization, or death within 30 days, and 125 (27%) within 90 days. In multivariate proportional hazards models, physical functioning and mental health in the lowest tertile, and lack of supplemental insurance predicted revisit, hospitalization, or death within 30 days after ED discharge. Poor physical functioning, missing mini-mental state examination, comorbidity, and ambulance transport to the initial ED visit predicted 90-day outcome. Problems with physical functioning, mental health and supplemental insurance are potentially remediable precursors of early morbidity among older patients after ED discharge. Future research should examine whether addressing these issues among the elderly population will lessen ED return visits, hospitalization, and mortality.

Emergency department utilization by noninstitutionalized elders.

OBJECTIVES: To the best of the authors' knowledge, no nationally representative, population-based study has characterized the proportion of elders using the emergency department (ED) and factors associated with ED use by elders. This article describes the proportion of elder Medicare beneficiaries using the ED and identifies attributes associated with elder ED users as compared with nonusers. METHODS: The 1993 Medicare Current Beneficiary Survey was used, a national, population-based, cross-sectional survey of Medicare beneficiaries linked with Medicare claims data. The study population was limited to 9,784 noninstitutionalized individuals aged 66 years or older. The Andersen model of health service utilization was used, which explains variation in ED use through a combination of predisposing (demographic and social), enabling (access to care), and need (comorbidity and health status) characteristics. RESULTS: Eighteen percent of the sample used the ED at least once during 1993. Univariate analysis showed ED users were older; were less educated and lived alone; had lower income and higher Charlson Comorbidity Index scores; and were less satisfied with their ability to access care than nonusers (p < 0.01, chi-square). Logistic regression identified older age, less education, living alone, higher comorbidity scores, worse reported health, and increased difficulties with activities of daily living as factors associated with ED use (p < 0.05). Need characteristics predicted ED use with the greatest accuracy. CONCLUSIONS: The proportion of elder ED users is slightly higher than previously reported among Medicare beneficiaries. Need (comorbidity and health status) characteristics predict ED utilization with the greatest accuracy.

Barriers to providing diabetes care in community health centers.

OBJECTIVE: We aimed to identify barriers to improving care for individuals with diabetes in community health centers. These findings are important because many such patients, as in most other practice settings, receive care that does not meet evidence-based standards. RESEARCH DESIGN AND METHODS: In 42 Midwestern health centers, we surveyed 389 health providers and administrators about the barriers they faced delivering diabetes care. We report on home blood glucose monitoring, HbA1c tests, dilated eye examinations, foot examinations, diet, and exercise, all of which are a subset of the larger clinical practice recommendations of the American Diabetes Association (ADA). RESULTS: Among the 279 (72%) respondents, providers perceived that patients were significantly less likely than providers to believe that key processes of care were important (overall mean on 30-point scale: providers 26.8, patients 18.2, P = 0.0001). Providers were more confident in their ability to instruct patients on diet and exercise than on their ability to help them make changes in these areas. Ratings of the importance of access to care and finances as barriers varied widely; however, >25% of the providers and administrators agreed that significant barriers included affordability of home blood glucose monitoring, HbA1c testing, dilated eye examination, and special diets; nonproximity of ophthalmologist; forgetting to order eye examinations and to examine patients' feet; time required to teach home blood glucose monitoring; and language or cultural barriers. CONCLUSIONS: Providers in health centers indicate a need to enhance behavioral change in diabetic patients. In addition, better health care delivery systems and reforms that improve the affordability, accessibility, and efficiency of care are also likely to help health centers meet ADA standards of care.

Variations in the care of elderly persons with diabetes among endocrinologists, general internists, and geriatricians.

BACKGROUND: The American Diabetes Association (ADA) clinical practice recommendations have been widely promoted, but they lack a geriatric-specific approach to care. We aimed to determine the style of care that endocrinologists, general internists, and geriatricians provided to their elderly patients with diabetes and to what extent these medical professionals adhered to the ADA standards. METHODS: We performed a retrospective cohort study of a stratified sample of 531 diabetic patients aged 65 years and older from the endocrinology, general internal medicine, and geriatrics clinics of an urban academic medical center. RESULTS: Patients of geriatricians were older, had higher comorbidity, and were more likely to be demented. The average number of diabetic complications was similar across the specialties, although patients of endocrinologists had higher prevalence of neuropathy and retinopathy compared with patients of geriatricians. Endocrinologists were more likely to use insulin, multiple types of insulin, and combined oral hypoglycemic and insulin therapies. Most patients had hemoglobin A1c measured, and average values were similarly high across specialties at 8.6%. Blood pressures were above 130/85 mm Hg in 85% of the patients. All specialties rarely measured urine microalbumin; geriatricians seldom performed fractionated cholesterol tests, and ophthalmology visits occurred in only half of the patients. CONCLUSION: Endocrinologists had the most aggressive, complex diabetes treatment regimens, although geriatricians had older patients with more dementia and lower prevalence of microvascular complications. Average hemoglobin A1c levels and blood pressures were higher than recommended among patients of all three specialties. Screening for diabetic complications and hyperlipidemia was lower than advised.

Quality of diabetes care in community health centers.

OBJECTIVES: This study assessed the quality of diabetes care in community health centers. METHODS: In 55 midwestern community health centers, we reviewed the charts of 2865 diabetic adults for American Diabetes Association measures of quality. RESULTS: On average, 70% of the patients in each community health center had measurements of glycosylated hemoglobin, 26% had dilated eye examinations, 66% had diet intervention, and 51% received foot care. The average glycosylated hemoglobin value per community health center was 8.6%. Practice guidelines were independently associated with higher quality of care. CONCLUSIONS: Rates of adherence to process measures of quality were relatively low among community health centers, compared with the targets established by the American Diabetes Association.

Specialty differences in the care of older patients with diabetes.

OBJECTIVES: To determine differences in health status, quality of care, and resource utilization among older diabetic Medicare patients cared for by endocrinologists, internists, family practitioners, and general practitioners. METHODS: The authors analyzed 1,637 patients with diabetes age 65 years or older in the 1994 Medicare Current Beneficiary Survey, a database that links patient surveys to 12 months of Medicare claims data. MEASURES: Measures of morbidity were Basic and Instrumental Activities of Daily Living, health perception, Charlson Comorbidity Index score, and diabetic complications. Quality of care markers were measurement of ophthalmologic visit, lipid testing, glycosylated hemoglobin measurement, mammography, influenza vaccination, early hospital readmission, outpatient follow-up, and patient satisfaction. Resource utilization included reimbursement, relative value units, physician and emergency department visits, and hospitalizations. Age, gender, race, and education were adjusted for in multivariable analyses. RESULTS: Compared with patients of family practitioners, patients of endocrinologists and internists had more comorbidity and diabetic complications but similar health perception and deficiencies in activities of daily living. The patients of endocrinologists also had higher utilization of ophthalmologic screening, lipid testing, and glycosylated hemoglobin measurement than the patients of generalist physicians, but similar rates of influenza vaccination. Patients of endocrinologists and internists had higher total reimbursement than those of family practitioners and general practitioners. Patient satisfaction was generally similar. CONCLUSIONS: Older diabetic patients of endocrinologists had higher utilization of diabetes-specific process of care measures and had similar functional status despite more diabetic complications. However, they received a more costly style of care than patients of family practitioners and general practitioners. Future work needs to explore the optimal coordination of care of diabetic patients among different health providers.

Screening and intervention for alcohol problems. A national survey of primary care physicians and psychiatrists.

OBJECTIVE: To describe adult primary care physicians' and psychiatrists' approach to alcohol screening and treatment, and to identify correlates of more optimal practices. DESIGN: Cross-sectional mailed survey. PARTICIPANTS: A national systematic sample of 2,000 physicians practicing general internal medicine, family medicine, obstetrics-gynecology, and psychiatry. MEASUREMENTS: Self-reported frequency of screening new outpatients, and treatment recommendations in patients with diagnosed alcohol problems, on 5-point Likert-type scales. MAIN RESULTS: Of the 853 respondent physicians (adjusted response rate, 57%), 88% usually or always ask new outpatients about alcohol use. When evaluating patients who drink, 47% regularly inquire about maximum amounts on an occasion, and 13% use formal alcohol screening tools. Only 82% routinely offer intervention to diagnosed problem drinkers. Psychiatrists had the most optimal practices; more consistent screening and intervention was also associated with greater confidence in alcohol history taking, familiarity with expert guidelines, and less concern that patients will object. CONCLUSIONS: Most primary care physicians and psychiatrists ask patients about alcohol use, but fewer use recommended screening protocols or offer formal treatment. A substantial minority of physicians miss the opportunity to intervene in alcohol problems. Efforts to improve physicians' screening and intervention for alcohol problems should address their confidence in their skills, familiarity with expert recommendations, and beliefs that patients object to their involvement

Developing a conceptual framework for understanding illness and attitudes in older, urban African Americans with diabetes.

PURPOSE: This study was conducted to better understand how older African Americans with diabetes view their illness, and to develop a conceptual framework for approaching their care. METHODS: Researchers conducted interviews of 19 African American patients 65 years or older who attended clinics at an urban academic medical center. The mean age of the patients was 73 years, 58% were female, 63% had a complication from diabetes, and 58% were taking insulin. Patients were asked open-ended questions about how diabetes affected their lives and their attitudes toward treatment. Data were analyzed through a grounded-theory perspective. RESULTS: Patients showed variation in the degree to which they believed that diabetes affected their lives and how aggressive they wished treatment to be. Themes included issues of quality of life, health beliefs, and the social context. Paradoxical, contradictory statements were common, expressing ambivalence and uncertainty regarding the effect of the illness and the treatment. CONCLUSIONS: Wide variation exists in the attitudes of older African Americans toward their diabetes and treatment. Patients frequently expressed ambivalence toward the care of their illness. Providers should explore these issues and help patients resolve their ambivalence if patient preferences are to be respected in the overall treatment plan.

Appropriateness of medication selection for older persons in an urban academic emergency department.

OBJECTIVES: To determine the frequency of potentially inappropriate medication selection for older persons presenting to the ED, the most common problematic drugs, risk factors for suboptimal medication selection, and whether use of these medications is associated with worse outcomes. METHODS: The authors performed a prospective cohort study of 898 patients 65 years or older who presented to an urban academic ED in 1995 and 1996. Seventy-nine percent of the patients were African-American and 43% did not graduate from high school. Potentially inappropriate medications and adverse drug-disease interactions were identified using the 1997 Beers explicit criteria for elders. During the three months after the initial visit, revisits to the ED or hospital, death, and changes in health-related quality of life were analyzed as measured by validated questions adapted from the Medical Outcomes Study. RESULTS: Upon presentation, 10.6% of the patients were taking a potentially inappropriate medication, 3.6% were given one in the ED, and 5.6% were prescribed one upon discharge from the ED. The most frequently prescribed potentially inappropriate medications in the ED were diphenhydramine, indomethacin, meperidine, and cyclobenzaprine. Emergency physicians added potentially inappropriate medications most often to patients with discharge diagnoses of musculoskeletal disorder, back pain, gout, and allergy or urticaria. Potentially adverse drug-disease interactions were relatively uncommon at presentation (5.2%), in the ED (0.6%), and on discharge from the ED (1.2%). Potentially inappropriate medications and adverse drug-disease interactions prescribed in the ED were not associated with higher rates of revisit to the ED, hospitalization, or death, but were correlated with worse physical function and pain. However, confidence intervals were wide for analyses of revisits and death. CONCLUSIONS: Suboptimal medication selection was fairly common and was associated with worse patient-reported health-related quality of life.

Older patients' health-related quality of life around an episode of emergency illness.

STUDY OBJECTIVES: We sought to describe older patients' health-related quality of life during a 4-month period surrounding a visit to the emergency department and to identify factors associated with less recovery. METHODS: We prospectively studied 983 patients 65 years or older who presented to an urban academic ED in 1995 and 1996. Eighty percent of the patients were African American, and 63% were women. The primary outcome measures were the Katz Index of Activities of Daily Living and revised validated questions from the Medical Outcomes Study Health Survey at 1 month before the ED visit, the time of the ED visit, and 2-week and 3-month follow-up periods. RESULTS: In general, patients worsened markedly during the illness and then improved, although not to baseline levels. After adjustment for demographic and social factors, the most consistently powerful predictors of poor recovery were more deficiencies in activities of daily living at baseline, reports of needing more help with everyday tasks, increasing Charlson Comorbidity Index scores, and requiring a proxy for the initial survey. CONCLUSION: Emergency physicians and primary care physicians should consider inquiring about functional status and the adequacy of help at home in addition to comorbid conditions for their acutely ill older patients to target those at greatest risk for poor recovery. Future work needs to test interventions that may improve the health-related quality of life of these vulnerable patients.

The effect of alcohol abuse on the health status of older adults seen in the emergency department.

OBJECTIVE: To examine the effect of alcohol abuse on the subsequent health status of elderly patients seen in an emergency department (ED). PATIENTS AND METHODS: A sample of 966 patients aged 65 or older who presented to one urban academic ED between the hours of 8 A.M. and 12 midnight was followed for 1 year. A personal interview was administered during the ED visit. Current problem drinkers had a score of 1 or greater on the CAGE questionnaire at ED presentation and drank within the prior 6 months; former problem drinkers had a score of 1 or greater on the CAGE questionnaire at ED presentation and a last drink more than 6 months previously. We used 13 items from the Medical Outcomes Study short form adapted to the ED setting and 6 items from the Index of Activities of Daily Living (ADL) to measure health status. RESULTS: In multivariate models for repeated-measures controlling for potential confounding factors, current problem drinkers had worse overall health (parameter estimate beta -3.6; 95% CI -7.1 to -0.04), and former problem drinkers had worse mental health (beta -3.6; CI -6.9 to -0.24) on follow-up. We could find no effect of problem drinking on physical health or social function. CONCLUSIONS: Current problem drinking is associated with worse self-perceived health among elderly patients in the year following presentation to an ED. The magnitude of decline in health perception may approximate the effect of having back pain, sciatica, or other musculoskeletal complaints. Elderly former problem drinkers suffer from more severe mental health problems over that same period.

Depressive symptoms and 3-year mortality in older hospitalized medical patients.

BACKGROUND: Depressive symptoms are common in hospitalized older persons. However, their relation to long-term mortality is unclear because few studies have rigorously considered potential confounders of the relation between depression and mortality, such as comorbid illness, functional impairment, and cognitive impairment. OBJECTIVE: To measure the association between depressive symptoms and long-term mortality in hospitalized older persons. DESIGN: Prospective cohort study. SETTING: General medical service of a teaching hospital. PATIENTS: 573 patients 70 years of age or older. MEASUREMENTS: Depressive symptoms (Geriatric Depression Scale score), severity of acute illness (Acute Physiology and Chronic Health Evaluation II score), burden of comorbid illness (Charlson comorbidity index score), physical function (a nurse assessed dependence in six activities of daily living), and cognitive function (modified Mini-Mental State Examination) were measured at hospital admission. Mortality over the 3 years after admission was determined from the National Death Index. Mortality rates among patients with six or more depressive symptoms were compared with those among patients with five or fewer symptoms. RESULTS: The mean age of the patients was 80 years; 68% of patients were women. Patients with six or more depressive symptoms had greater comorbid illness, functional impairment, and cognitive impairment at admission than patients with fewer depressive symptoms. Three-year mortality was higher in patients with six or more depressive symptoms (56% compared with 40%; hazard ratio, 1.56 [95% CI, 1.22 to 2.00]; P < 0.001). After adjustment for age, acute illness severity, comorbid illness, functional impairment, and cognitive impairment at the time of admission, patients with six or more depressive symptoms continued to have a higher mortality rate during the 3 years after admission (hazard ratio, 1.34 [CI, 1.03 to 1.73]). Although depressive symptoms contributed less to the mortality rate than did the total burden of comorbid medical illnesses, the excess mortality rate associated with depressive symptoms was greater than that conferred by one additional comorbid medical condition. CONCLUSIONS: Depressive symptoms are associated with long-term mortality in older patients hospitalized with medical illnesses. This association is not fully explained by greater levels of comorbid illness, functional impairment, and cognitive impairment in patients with more depressive symptoms.

Carboxy-substituted cinnamides: a novel series of potent, orally active LTB4 receptor antagonists.

A series of carboxy-substituted cinnamides were investigated as antagonists of the human cell surface leukotriene B4 (LTB4) receptor. Binding was determined through measurement of [3H]LTB4 displacement from human neutrophils. Receptor antagonism was confirmed through a functional assay, which measures inhibition of Ca2+ release in human neutrophils. Potent antagonists were discovered through optimization of a random screening hit, a p-(alpha-methylbenzyloxy)cinnamide, having low-micromolar activity. Substantial improvement of in vitro potency was realized by the attachment of a carboxylic acid moiety to the cinnamide phenyl ring through a flexible tether, leading to identification of compounds with low-nanomolar potency. Modification of the benzyloxy substituent, either through ortho-substitution on the benzyloxy phenyl group or through replacement of the ether oxygen with a methylene or sulfur atom, produced achiral antagonists of equal or greater potency. The most potent compounds in vitro were assayed for oral activity using the arachidonic acid-induced mouse ear edema model of inflammation. Several compounds in this series were found to significantly inhibit edema formation and myeloperoxidase activity in this model up to 17 h after oral administration. Representatives of this series have been shown to be potent and long-acting orally active inhibitors of the LTB4 receptor.
