Abstract
Across four studies, we investigated whether perceptions of children’s pain are influenced by their socioeconomic status (SES). We found evidence that children with low SES were believed to feel less pain than children with high SES (Study 1), and this effect was not moderated by child’s age (Study 2). Next, we examined life hardship as a mediator of this effect among children, finding that children with low SES were rated as having lived a harder life and thus as feeling less pain (Study 3). Finally, we examined downstream consequences for hypothetical treatment recommendations. We found that participants perceived children with low SES as less sensitive to pain and therefore as requiring less pain treatment than children with high SES (Study 4). Thus, we consistently observe that stereotypes of low-SES individuals as insensitive to pain may manifest in judgments of children and their recommended pain care. Implications of this work for theory and medical practice are discussed.

Postgrad Med J 2021; 98:830-836. [PMID: 37063042 DOI: 10.1136/postgradmedj-2021-140735] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 08/31/2021] [Indexed: 11/03/2022]
Abstract
INTRODUCTION Hospital quality improvement and hospital performance are commonly evaluated using parameters such as average length of stay (LOS), patient safety measures and rates of hospital readmission. Thirty-day readmission (30-DR) rates are widely used as a quality indicator and a quantifiable metric for hospitals since patients are often readmitted for the exacerbation of conditions from index admission. The quality of patient education and postdischarge care can influence readmission rates. We report the 30-DR rates of patients with asthma using a national dataset for the year 2013. OBJECTIVES The aim of our study was to assess the 30- day readmission (30-DR) rate as well as, the causes and predictors of readmissions. STUDY DESIGNS/METHODS Using the Nationwide Readmission Database (NRD) (2013), we identified primary discharge diagnoses of asthma by using International Classification of Diseases, Ninth Revision, Clinical Modification code '493'. Categorical and continuous variables were assessed by a χ2 test and a Student's t-test, respectively. The independent predictors of unplanned 30-DR were detected by multivariate analysis. We used sampling weights, which are provided in the NRD, to generate the national estimates. RESULTS There were 130 490 (weighted N=311 173) inpatient asthma admissions during 2013. The overall 30-DR for asthma was 11.9%. The associated factors for 30-DR were age 45-84 years (40.32% vs 29.05%; p<0.001), enrolment in Medicare (49.33% vs 30.61% p<0.001), extended LOS (mean, 4.40±0.06 vs 3.25±0.04 days; p<0.001), higher mean cost (US$8593.91 vs US$6741.31; p<0.001) and higher disposition against medical advice (DAMA) (4.14% vs 1.51%; p<0.001). The factors that increased the chance of 30-DR were advanced age (≥45-64 vs ≤17 years; OR 4.61, 95% CI 4.04 to 5.27, p<0.0001), male sex (OR 1.19, 95% CI 1.13 to 1.26, p<0.0001), a higher Charlson Comorbidity Index (CCI) (OR 1.16, 95% CI 1.14 to 1.18, p<0.0001), DAMA (OR 2.32, 95% CI 2.08 to 2.59, p<0.0001), non-compliance with medication (OR 1.34, 95% CI 1.24 to 1.46, p<0.0001), post-traumatic stress disorder (OR 1.48, 95% CI 1.22 to 1.79, p<0.0001), alcohol use (OR 1.45, 95% CI 1.27 to 1.65, p<0.0001), gastro-oesophageal reflux disease (OR 1.20, 95% CI 1.14 to 1.27, p<0.0001), obstructive sleep apnoea (OR 1.11, 95% CI 1.03 to 1.18, p<0.0042) and hypertension (OR 1.11, 95% CI 1.06 to 1.17, p<0.0001). CONCLUSIONS We found that the overall 30-DR rate for asthma was 11.9% all-cause readmission. Major causes of 30-DR were asthma exacerbation (36.74%), chronic obstructive pulmonary disease (11.47%), respiratory failure (6.46%), non-specific pneumonia (6.19%), septicaemia (3.61%) and congestive heart failure (3.32%). One-fourth of the revisits occurred in the first week, while half of the revisits took place in the first 2 weeks. Education regarding illness and the importance of medicine compliance could play a significant role in preventing asthma-related readmission.

Abstract
Objective: This study aimed to estimate asthma control at specialist treatment centers in four Latin American countries and assess factors influencing poor asthma control.Methods: Patients aged ≥12 years with an asthma diagnosis and asthma medication prescription, followed at outpatient specialist centers in Argentina, Chile, Colombia, and Mexico, were included. The study received all applicable ethical approvals. The Asthma Control Test (ACT) was used to classify patients as having controlled (ACT 20-25) or uncontrolled (ACT ≤19) asthma. Frequency and statistical tests were used to assess the association between hospital admissions/exacerbations/emergency department (ED) visits and uncontrolled asthma; multivariate logistic regression was used to assess the association of uncontrolled asthma with clinical/demographic variables.Results: A total of 594 patients were included. Overall controlled-asthma prevalence was 43.4% (95% confidence interval [CI]: 39.0, 47.4). Patients with uncontrolled asthma were more likely to be women (adjusted odds ratio [aOR]: 1.85; p = 0.003), non-white (aOR: 2.14; p < 0.001), obese (aOR: 1.71; p = 0.036), to have a low monthly family income (aOR: 1.75; p = 0.004), to have severe asthma (aOR:1.59; p = 0.26), and, compared with patients with controlled asthma, to have a higher likelihood of asthma exacerbations (34.5% vs. 15.9%; p < 0.001), hospital admissions (6.9% vs. 3.1%; p = 0.042), and ED visits (34.5% vs. 15.9%; p < 0.001) due to asthma.Conclusions: Even in specialist ambulatory services, fewer than half of patients were classified as having controlled asthma. The proportion of uncontrolled patients varied according to clinical and demographic variables.

A patient advocate to facilitate access and improve communication, care, and outcomes in adults with moderate or severe asthma: Rationale, design, and methods of a randomized controlled trial. Contemp Clin Trials 2017; 56:34-45.

Abstract
Few interventions to improve asthma outcomes have targeted low-income minority adults. Even fewer have focused on the real-world practice where care is delivered. We adapted a patient navigator, here called a Patient Advocate (PA), a term preferred by patients, to facilitate and maintain access to chronic care for adults with moderate or severe asthma and prevalent co-morbidities recruited from clinics serving low-income urban neighborhoods. We describe the planning, design, methodology (informed by patient and provider focus groups), baseline results, and challenges of an ongoing randomized controlled trial of 312 adults of a PA intervention implemented in a variety of practices. The PA coaches, models, and assists participants with preparations for a visit with the asthma clinician; attends the visit with permission of participant and provider; and confirms participants' understanding of what transpired at the visit. The PA facilitates scheduling, obtaining insurance coverage, overcoming patients' unique social and administrative barriers to carrying out medical advice and transfer of information between providers and patients. PA activities are individualized, take account of comorbidities, and are generalizable to other chronic diseases. PAs are recent college graduates interested in health-related careers, research experience, working with patients, and generally have the same race/ethnicity distribution as potential participants. We test whether the PA intervention, compared to usual care, is associated with improved and sustained asthma control and other asthma outcomes (prednisone bursts, ED visits, hospitalizations, quality of life, FEV1) relative to baseline. Mediators and moderators of the PA-asthma outcome relationship are examined along with the intervention's cost-effectiveness.

Abstract
Background Despite the urgent need for evidence to guide the end-of-life (EOL) care for patients with chronic kidney disease (CKD), we have limited knowledge of the costs and intensity of EOL care in this population. The present study examined patterns and predictors for EOL care intensity among elderly patients with CKD. Methods We conducted a retrospective nationwide cohort study utilizing the Taiwan National Health Insurance (NHI) Research Database. A total of 65,124 CKD patients aged ≥ 60 years, who died in hospitals or shortly after discharge between 2002 and 2012 were analyzed. The primary outcomes were inpatient expenses and use of surgical interventions in the last 30 days of life. Utilization of intensive care unit (ICU), mechanical ventilation, resuscitation, and dialysis was also examined in a sub-sample of 2072 patients with detailed prescription data. Multivariate log-linear and logistic regression analyses were performed to assess patient-, physician-, and facility-specific predictors and the potential impact of a 2009 payment policy to reimburse hospice care for non-cancer patients. Results During the last 30 days of life, average inpatients costs for elderly CKD patients were approximately US$10,260, with 40.9% receiving surgical interventions, 40.2% experiencing ICU admission, 45.3% undergoing mechanical ventilation, 14.7% receiving resuscitation and 42.0% receiving dialysis. Significant variability was observed in the inpatient costs and use of intensive services. Costs were lower among individuals with the following characteristics: advanced age; high income; high Charlson Comorbidity Index scores; treatment by older physicians, nephrologists, and family medicine physicians; and treatment at local hospitals. Similar findings were obtained for the use of surgical interventions and other intensive services. A declining trend was detected in the costs of EOL care, use of surgical interventions and resuscitation between 2009 and 2012, which is consistent with the impact of a 2009 NHI payment policy to reimburse non-cancer hospice care. Conclusions Overall EOL costs and rates of intensive service use among older patients with CKD were high, with significant variability across various patient and provider characteristics. Several opportunities exist for providers and policy makers to reduce costs and enhance the value of EOL care for this population.

Abstract
BACKGROUND Asthma control is increasingly used as an outcome measure in asthma trials. Economic evaluations of asthma interventions require converting the impact of interventions on control to impact on resource use. The purpose of this study was to estimate the savings in direct costs by achieving asthma symptom control as defined in the Global Initiative for Asthma (GINA) 2014 management strategy. METHODS Adolescents and adults with asthma were recruited through random digit dialing. Asthma control per GINA and the use of healthcare resources were assessed at baseline and three-monthly visits up to 1 year. We used regression models to associate costs, measured in 2012 Canadian dollars ($), with symptom control, adjusting for potential confounding variables. RESULTS The final sample included 517 individuals (average age 48.9, 65.8% female) with mostly mild-moderate asthma contributing 2033 follow-up visits. In 598 (29.4%), 809 (39.8%), and 626 (30.8%) of visits, asthma was symptomatically controlled, partially controlled, or uncontrolled, respectively. The average 3-month costs of asthma were $134.5. Of these, 20.5% were attributable to inpatient care, 47.8% to outpatient care, and 31.5% to medication. Compared to controlled asthma, partially controlled asthma was associated with a nonsignificant increase of $9.5 (95% CI -$13.6 - $32.6) in adjusted 3-month costs and uncontrolled asthma with a statistically significant increase of $81.7 (95% CI $48.5 - $114.9). CONCLUSION A substantial fraction of this population-based sample of largely mild-moderate asthmatics was symptomatically uncontrolled. Achieving symptom control was associated with a reduction in direct costs. The adjusted values from this study can be used to inform cost-effectiveness analyses of asthma treatments.

Abstract
OBJECTIVE Estimate the association between smoking and emergency care in the past 12 months among asthmatic adults in a nationally representative sample. METHODS Using the 2011 Asthma Call-Back Survey, the association between smoking status and emergency department (ED) and urgent visits among asthmatic adults (n = 12 339) was assessed through multivariable logistic regression by a cross-sectional study design. Analyses used survey weights for US population-based estimates. Attributable and population attributable risk were calculated to describe the potential benefits of smoking cessation. RESULTS Adjusting for potential confounders, during the past 12 months former smokers had 1.30 (95% CI: 0.97, 1.74) times the odds and current smokers had 1.46 (95% CI: 1.05, 2.03) times the odds of visiting the ED compared to never smokers. Former smokers had 1.28 (95% CI: 0.99, 1.65) times the odds and current smokers had 1.29 (95% CI: 0.96, 1.73) times the odds of urgent visits compared to never smokers. Among adult asthmatics, an estimated 9% of ED visits and 6% of urgent visits can be attributed to current smoking while 7% of ED visits and 7% of urgent visits can be attributed to former smoking. CONCLUSIONS Current and former smokers are more likely to need emergency care than never smokers. About 10% of emergency care visits among asthmatics can be attributed to smoking assuming smoking is causally related to emergency care. Long-term effective management of asthma, particularly the prevention and cessation of smoking, could reduce emergency care use and health care costs.

Abstract
Purpose - NIH guidelines recommend maintenance treatment of persistent moderate or severe childhood asthma with preventive anti-inflammatory medication (inhaled corticosteroids, cromolyn or nedocromil). The objective was to determine if the NIH guidelines for the treatment of childhood asthma were implemented by examining the prevalence of prescribing preventive medication.Methods - This was a non-concurrent cohort study of 311 children (aged 2 to 19 years) who were treated for asthma between January and December 1994 by nine Medicaid managed care plans in the northeastern USA.Results - Preventive medications were prescribed at least once to 61.1% of the children with moderate or severe asthma and to 27.1% of the children with mild asthma. Logistic regression analyses indicated prescribing preventive medication was associated with moderate or severe asthma (aOR 5.34, 95% CI 3.22 - 8.83) and age 5 to 19 years (aOR 2.11, 95% CI 1.19 - 3.72). Prescribing preventive medication was also associated with a prior emergency department visit (aOR 2.27, 95% CI 1.24 - 4.16), after adjusting for age.Conclusions - Prescribing preventive medications is related to sentinel clinical events and the NIH recommendations are not routinely implemented for all children with moderate or severe asthma during this study period.

Abstract
CONTEXT Computerized drug alerts for psychotropic drugs are expected to reduce fall-related injuries in older adults. However, physicians over-ride most alerts because they believe the benefit of the drugs exceeds the risk. OBJECTIVE To determine whether computerized prescribing decision support with patient-specific risk estimates would increase physician response to psychotropic drug alerts and reduce injury risk in older people. DESIGN Cluster randomized controlled trial of 81 family physicians and 5628 of their patients aged 65 and older who were prescribed psychotropic medication. INTERVENTION Intervention physicians received information about patient-specific risk of injury computed at the time of each visit using statistical models of non-modifiable risk factors and psychotropic drug doses. Risk thermometers presented changes in absolute and relative risk with each change in drug treatment. Control physicians received commercial drug alerts. MAIN OUTCOME MEASURES Injury risk at the end of follow-up based on psychotropic drug doses and non-modifiable risk factors. Electronic health records and provincial insurance administrative data were used to measure outcomes. RESULTS Mean patient age was 75.2 years. Baseline risk of injury was 3.94 per 100 patients per year. Intermediate-acting benzodiazepines (56.2%) were the most common psychotropic drug. Intervention physicians reviewed therapy in 83.3% of visits and modified therapy in 24.6%. The intervention reduced the risk of injury by 1.7 injuries per 1000 patients (95% CI 0.2/1000 to 3.2/1000; p=0.02). The effect of the intervention was greater for patients with higher baseline risks of injury (p<0.03). CONCLUSION Patient-specific risk estimates provide an effective method of reducing the risk of injury for high-risk older people. TRIAL REGISTRATION NUMBER clinicaltrials.gov Identifier: NCT00818285.

Abstract
BACKGROUND Patients with moderate or severe asthma, particularly those who are minority or poor, often encounter significant personal, clinical practice, and health system barriers to accessing care. OBJECTIVE To explore the ideas of patients and providers for potentially feasible, individualized, cost-effective ways to reduce obstacles to care by providing social support using a patient advocate or navigator. METHODS The authors conducted four focus groups of adults with moderate or severe asthma. Participants were recruited from clinics serving low-income and minority urban neighborhoods. Data from these patient focus groups were shared with two additional focus groups, one of nurses and one of physicians. Researchers independently coded and agreed upon themes from all focus groups, which were categorized by types of social support: instrumental (physical aid), informational (educational), emotional (empathizing), validation (comparisons to others). RESULTS Patients and providers agreed that a patient navigator could help patients manage asthma by giving social support. Both groups found instrumental and informational support most important. However, patients desired more instrumental help whereas providers focused on informational support. Physicians stressed review of medical information whereas patients wanted information to complete administrative tasks. Providers and patients agreed that the patient navigator's role in asthma would need to address both short-term care of exacerbations and enhance long-term chronic self-management by working with practice personnel. CONCLUSIONS Along with medical information, there is a need for providers to connect patients to instrumental support relevant to acute and long-term asthma-self-management.

Abstract
Asthma is a highly prevalent chronic respiratory disease affecting 300 million people world-wide. A significant fraction of the cost and morbidity of asthma derives from acute care for asthma exacerbations. In the United States alone, there are approximately 15 million outpatient visits, 2 million emergency room visits, and 500,000 hospitalizations each year for management of acute asthma. Common respiratory viruses, especially rhinoviruses, cause the majority of exacerbations in children and adults. Infection of airway epithelial cells with rhinovirus causes the release of pro-inflammatory cytokines and chemokines, as well as recruitment of inflammatory cells, particularly neutrophils, lymphocytes, and eosinophils. The host response to viral infection is likely to influence susceptibility to asthma exacerbation. Having had at least one exacerbation is an important risk factor for recurrent exacerbations suggesting an 'exacerbation-prone' subset of asthmatics. Factors underlying the 'exacerbation-prone' phenotype are incompletely understood but include extrinsic factors: cigarette smoking, medication non-compliance, psychosocial factors, and co-morbidities such as gastroesophageal reflux disease, rhinosinusitis, obesity, and intolerance to non-steroidal anti-inflammatory medications; as well as intrinsic factors such as deficient epithelial cell production of the anti-viral type I interferons (IFN-alpha and IFN-beta). A better understanding of the biologic mechanisms of host susceptibility to recurrent exacerbations will be important for developing more effective preventions and treatments aimed at reducing the significant cost and morbidity associated with this important global health problem.

Abstract
This cross sectional descriptive study sought to identify perceived barriers to follow-up care for adult asthmatics who are followed in two community health care facilities. A second purpose of the study was to determine the effect of any barriers to Health Related Quality of Life (HRQL) and compliance in the sample. Thirty-four adults completed a demographic and health status survey, the MiniAQLQ and the EWash Access to Health Care Survey. "Long waiting time in provider's office," "someone had to miss work," "cost of care too much, "and "long wait for an appointment" were the most prevalent perceived barriers in the sample. "Lack of transportation" was significantly associated with study participants who receive health care at one site or who stated the emergency room as their usual place of care. "Someone had to miss work" was significantly correlated with the following variables: employment, a higher annual household income, 1-2 daily medications for asthma, no overnight hospitalizations for asthma and no psychological co-morbidities. A higher reported HQOL was significantly correlated with study participants whose medical care needs were met and found access to local health care services. The only perceived barrier that was significantly correlated with compliance was study participants who "sometimes" had to reschedule an appointment with a health care provider due to "lack of transportation." The present study suggests that strategies designed to decrease the perceived barriers might improve compliance with the treatment regime, thus decreasing costs, absenteeism, and lack of continuity.

Abstract
OBJECTIVES Prescribing alerts generated by computerized drug decision support (CDDS) may prevent drug-related morbidity. However, the vast majority of alerts are ignored because of clinical irrelevance. The ability to customize commercial alert systems should improve physician acceptance because the physician can select the circumstances and types of drug alerts that are viewed. We tested the effectiveness of two approaches to medication alert customization to reduce prevalence of prescribing problems: on-physician-demand versus computer-triggered decision support. Physicians in each study condition were able to preset levels that triggered alerts. DESIGN This was a cluster trial with 28 primary care physicians randomized to either automated or on-demand CDDS in the MOXXI drug management system for 3,449 of their patients seen over the next 6 months. MEASUREMENTS The CDDS generated alerts for prescribing problems that could be customized by severity level. Prescribing problems included dosing errors, drug-drug, age, allergy, and disease interactions. Physicians randomized to on-demand activated the drug review when they considered it clinically relevant, whereas physicians randomized to computer-triggered decision support viewed all alerts for electronic prescriptions in accordance with the severity level they selected for both prevalent and incident problems. Data from administrative claims and MOXXI were used to measure the difference in the prevalence of prescribing problems at the end of follow-up. RESULTS During follow-up, 50% of the physicians receiving computer-triggered alerts modified the alert threshold (n = 7), and 21% of the physicians in the alert-on-demand group modified the alert level (n = 3). In the on-demand group 4,445 prescribing problems were identified, 41 (0.9%) were seen by requested drug review, and in 31 problems (75.6%) the prescription was revised. In comparison, 668 (10.3%) of the 6,505 prescribing problems in the computer-triggered group were seen, and 81 (12.1%) were revised. The majority of alerts were ignored because the benefit was judged greater than the risk, the interaction was known, or the interaction was considered clinically not important (computer-triggered: 75.8% of 585 ignored alerts; on-demand: 90% of 10 ignored alerts). At the end of follow-up, there was a significant reduction in therapeutic duplication problems in the computer-triggered group (odds ratio 0.55; p = 0.02) but no difference in the overall prevalence of prescribing problems. CONCLUSION Customization of computer-triggered alert systems is more useful in detecting and resolving prescribing problems than on-demand review, but neither approach was effective in reducing prescribing problems. New strategies are needed to maximize the use of drug decision support systems to reduce drug-related morbidity.

Abstract
OBJECTIVE This long-term prospective study was conducted in African Americans with persistent asthma to examine the safety and effectiveness of the combination of the inhaled corticosteroid, fluticasone propionate (FP), and the long-acting beta-agonist, salmeterol, compared with FP alone. RESEARCH AND DESIGN METHODS This was a randomized, double-blind, parallel group, multi-center trial in adolescent and adult subjects >/=12 years of age symptomatic on a low dose of an inhaled corticosteroid (ICS). The study consisted of a 2-week screening period on low dose ICS; a 4-week open-label FP 250 mcg twice daily (BID) run-in; a 52-week double-blind period (FP/salmeterol [FSC] 100/50 mcg [n=239] or FP 100 mcg [n=236] BID), and a 4-week FP 250 mcg BID run-out period. Annualized exacerbation rate was the primary outcome for comparing the two treatments. Other measures of asthma control included peak expiratory flow, asthma symptoms, and albuterol use. Safety was assessed through adverse events. RESULTS Exacerbation rates were not significantly different in those treated with FSC 100/50 mcg (0.449 per year) compared with FP 100 mcg (0.529 per year, p=0.169). When the per-protocol analysis was applied, the rates were 0.465 and 0.769 per year for FSC 100/50 mcg and FP 100 mcg, respectively. Treatment with FSC 100/50 mcg provided statistically greater improvements in lung function measures and nighttime awakenings (p</=0.050) and demonstrated numerically lower daily symptoms (p=0.216) and albuterol use (p=0.122). Two subjects treated with FSC 100/50 mcg were hospitalized for an asthma exacerbation compared to three treated with FP 100 mcg. The overall incidence of adverse effects during double-blind treatment was similar between the FSC 100/50 mcg and FP 100 mcg treatment groups (61% and 68%, respectively). Frequent study visits were required of subjects during this long-term study, and it remains unknown whether this intervention may affect generalizability. CONCLUSION In this large, prospective study among African Americans with asthma, the addition of salmeterol to FP resulted in a similar low rate of exacerbations and improved other markers of asthma control. Both FSC 100/50 mcg and FP 100 mcg were well-tolerated, and the overall safety-profiles were similar over 1 year of treatment.

Abstract
Asthma is a common, chronic illness with substantial morbidity, especially for racial and ethnic minorities in the United States. The care of the patient with asthma is complex and depends ideally on excellent communication between patients and health-care providers. Communication is essential for the patient to communicate the severity of his or her illness, as well as for the health-care provider to instruct patients on pharmacologic and nonpharmacologic care. This article describes evidence for poor provider/patient communication as a contributor to health-care disparities for minority patients with asthma. Communication problems stem from issues with patients, health-care providers, and health-care systems. It is likely that asthma disparities can be improved, in part, by improving patient/provider communication. While much is known presently about the problem of patient/provider communication in asthma, there is a need to improve and extend the evidence base on the role of effective communication of asthma care and the links to outcomes for minorities. Additional studies are needed that document the extent to which problems with doctor/patient communication lead to inadequate care and poor outcomes for minorities with asthma, as well as mechanisms by which these disparities occur.

Abstract
BACKGROUND The use of acute health care resources for asthma is considerable. Disease severity is an established risk factor, but ethnicity and health care factors are less well studied. OBJECTIVE To investigate the independent associations of ethnicity and health care factors with acute resource use for asthma. METHODS Longitudinal data from a national adult asthma management program providing universal access to care were analyzed. Outcome measures were unscheduled physician visits with urgent nebulization, emergency department (ED) visits, and hospitalizations. RESULTS In multivariate analyses, markers of disease severity were found to be significantly associated with all acute resource use. After controlling for disease severity, ethnicity was associated with increased risk of all acute resource use; Indian (vs Chinese) ethnicity was associated with increased risk of unscheduled physician visits (hazard ratio [HR], 1.32; 95% confidence interval [CI], 1.03-1.70), ED visits (HR, 1.61; 95% CI, 1.12-2.32), and hospitalizations (HR, 1.49; 95% CI, 1.03-2.16). Malay ethnicity was associated with unscheduled physician visits (HR, 1.30; 95% CI, 1.01-1.68) and ED visits (HR, 1.55; 95% CI, 1.09-2.19). Default of follow-up appointments was associated with unscheduled physician visits (HR, 1.47; 95% CI, 1.08-2.00), ED visits (HR, 2.35; 95% CI, 1.59-3.45), and hospitalizations (HR, 1.74; 95% CI, 1.09-2.76). Poor inhaler technique was associated with ED visits (HR, 1.86; 95% CI, 1.05-3.30) and smoking with unscheduled physician visits (HR, 1.38; 95% CI, 1.09-1.76). CONCLUSIONS In addition to markers of asthma severity, ethnicity, smoking, discontinuity of care, and self-care behavior are risk factors for acute resource utilization and represent target groups and elements of asthma intervention for improving asthma outcomes.

Abstract
RATIONALE Hospitalizations for asthma exacerbations are common in the United States, but there are no national estimates of outcomes in this population. It is also not known if race disparities in asthma deaths exist among hospitalized patients. OBJECTIVES To estimate outcomes of patients hospitalized for asthma in the United States and to determine if the risk of death in this population is higher among black patients compared with white patients. METHODS We used the Nationwide Inpatient Sample for 2000. Admissions for asthma exacerbations among patients > 5 yr of age were included. Mortality was the primary outcome; secondary outcomes were length of stay and total hospital charges. MEASUREMENTS AND MAIN RESULTS In-hospital asthma mortality was 0.5% (99% confidence interval [CI], 0.4-0.6), with mean hospital stay of 2.7 d (99% CI, 2.6-2.8 d) and 9,078 dollars (99% CI, 8,300-9,855 dollars) in hospital charges. Deaths in this population accounted for about one-third of all asthma deaths reported in the United States. Black patients hospitalized for asthma exacerbations were less likely to die when compared with white patients (0.3 vs. 0.6%; p < 0.001). However, in multivariable analyses, there were no significant race differences in hospital deaths. CONCLUSIONS Mortality among patients hospitalized for asthma exacerbations accounts for one-third of all deaths from asthma. The higher overall risk of death from asthma in black patients compared with white patients in the United States is not explained by race differences in hospital deaths and therefore is attributable to factors preceding hospitalization.

Abstract
RATIONALE African Americans acutely ill with asthma come to emergency departments more frequently and are admitted to hospital more often than whites but the reasons are unclear. OBJECTIVES To determine whether such phenomena represent racial differences in attack severity or limited effectiveness of beta(2)-agonist therapy. METHODS AND MAIN RESULTS We contrasted clinical features, airflow limitation, and albuterol responsiveness in adults acutely ill with asthma, 155 of whom where African American and 140 white, as they presented to eight emergency departments. Assessments were standardized across institutions using a care path, and admission and discharge decisions were made according to predetermined criteria. The degree of obstruction was measured by peak expiratory flow rates. The clinical features of both groups were similar. The African Americans, however, had lower flow rates (p = 0.002), and more of them experienced severe or potentially life threatening episodes (p < 0.001). Albuterol was equally efficacious in both populations and there were no differences in the post-treatment flow rates achieved irrespective of the initial attack intensity. There were no racial differences in admission/discharge ratios. CONCLUSIONS Our data indicate that African Americans with asthma tend to present with somewhat more intense attacks than whites, but they respond equally well to routine treatment. Similarly, there were no racial disparities in hospitalizations when standard criteria are employed.

Abstract
Asthma is a chronic disease of airway inflammation that affects all age groups. Despite national treatment recommendations and the availability of effective controller medications, asthma morbidity remains pervasive and currently represents a considerable socioeconomic burden. Asthma may be intermittent or persistent; persistent asthma may be mild, moderate, or severe. Many factors influence asthma severity, both on a short-term basis and over time. In individual patients, asthma severity may fluctuate because of physiologic, environmental, socioeconomic, or behavioral factors. Inhaled corticosteroids (ICSs) are safe and well tolerated, and are the preferred long-term treatment for controlling persistent asthma of all severities in adults and children. Awareness of episodic changes in asthma severity, with subsequent tailored adjustment in guideline-based ICS therapy, should enable optimal control of asthma with minimal medication requirements.

Abstract
Adherence is important with all medications. It can be more difficult with inhaled steroids in light of concern about adverse effects. Although the degree of fear regarding inhaled steroids is difficult to quantify, it appears to be an important factor in adherence. These fears exist for several reasons, including misinformation obtained from such sources as the Internet. To improve adherence and decrease morbidity and mortality, it is vital that health care providers are aware of potential barriers to adherence. Measures such as simplifying and properly explaining medication regimens are helpful. Just as important is the establishment of a strong patient-provider relationship. This makes it easier to convince patients of the need for recommended medications. If the provider is able to effectively communicate and convince the patient of the benefit/risk ratio of steroids, improved patient outcomes can be achieved.

Abstract
OBJECTIVES To investigate racial/ethnic differences in acute asthma among adults presenting to the emergency department (ED), and to determine whether observed differences are attributable to socioeconomic status (SES). DESIGN Prospective cohort studies performed during 1996 to 1998 by the Multicenter Airway Research Collaboration. Using a standardized protocol, researchers provided 24-h coverage for a median duration of 2 weeks per year. Adults with acute asthma were interviewed in the ED and by telephone 2 weeks after hospital discharge. PARTICIPANTS Sixty-four North American EDs. RESULTS A total of 1,847 patients were enrolled into the study. Black and Hispanic asthma patients had a history of more hospitalizations than did whites (ever-hospitalized patients: black, 66%; Hispanic, 63%; white, 54%; p < 0.001; patients hospitalized in the past year: black, 31%; Hispanic, 33%; white, 25%; p < 0.05) and more frequent ED use (median use in past year: black, three visits; Hispanic, three visits; white, one visit; p < 0.001). The mean initial peak expiratory flow rate (PEFR) was lower in blacks and Hispanics (black, 47%; Hispanic, 47%; white, 52%; p < 0.001). For most factors, ED management did not differ based on race/ethnicity. After accounting for several confounding variables, blacks and Hispanics were twice as likely to be admitted to the hospital. Blacks and Hispanics also were more likely to report continued severe symptoms 2 weeks after hospital discharge (blacks, 24%; Hispanic, 31%; white, 19%; p < 0.01). After adjusting for sociodemographic factors, the race/ethnicity differences in initial PEFR and posthospital discharge symptoms were markedly reduced. CONCLUSION Despite significant racial/ethnic differences in chronic asthma severity, initial PEFR at ED presentation, and posthospital discharge outcome, ED management during the index visit was fairly similar for all racial groups. SES appears to account for most of the observed acute asthma differences, although hospital admission rates were higher among black and Hispanic patients after adjustment for confounding factors. Despite asthma treatment advances, race/ethnicity-based deficiencies persist. Health-care providers and policymakers might specifically target the ED as a place to initiate interventions designed to reduce race-based disparities in health.

Abstract
The aim was to compare health-related quality of life (HRQL) in patients with asthma from 4 countries, and to investigate the correlations between HRQL and clinical indices.341 patients; 140 (Sweden), 54 (Norway), 65 (the Netherlands) and 82 (Greece) were treated with formoterol fumarate 4.5 microg or with terbutaline sulphate 0.5mg for 12 weeks inhaled 'on demand' via Turbuhaler. The Asthma Quality of Life Questionnaire (AQLQ) and clinical indices were assessed. The mean baseline AQLQ overall scores in Sweden (4.97), in the Netherlands (5.04), in Norway (4.68) and in Greece (4.68) were in the same range, however, with a significant difference between the four countries (p=0.038). When comparing AQLQ, activity limitation and symptoms domains, the differences between the countries were not statistically significant. The cross-sectional correlations between AQLQ overall score and the clinical indices were similar in all four countries. The magnitude of change in AQLQ was consistent with the other clinical variables. The correlations between change in AQLQ overall score and change in clinical indices were low to medium in all countries. In conclusion, the consistency of cross-sectional correlations between the AQLQ overall and clinical indices across countries supports the validity of translations of the AQLQ used in this study. There were differences in baseline values between the countries. The treatment response in AQLQ differed to the same extent as other clinical indices. When combining HRQL data from different countries, there might be cultural, gender and socio-economic differences, explaining different responses to treatment.

Abstract
From October 2001 through September 2002, reports of clinical research on asthma in adults focused on the epidemiology of asthma, the investigation of pharmacologic and immunologic therapy in the context of new national guidelines, and discussions of medical economics. Epidemiologic findings include the observation that overall mortality has declined and hospitalizations have remained constant in the United States since 1995, although these rates are at least twice as high in Blacks. Socially and economically disadvantaged groups receive poorer health care for asthma. Young children who have fewer than 5 episodes of wheezing in conjunction with respiratory infections generally have a good prognosis and do not have compromised lung function as adults. Pharmacologic reports and the National Asthma Education and Prevention Program Update recommend low- to medium-dose inhaled steroids combined with a long-acting beta-agonist as the preferred therapy for moderate persistent asthma. The use of chlorofluorocarbon-free medications for asthma is increasing. Medications comprise the largest cost category for asthma.

Abstract
We evaluated the relation between socioeconomic factors and hospitalization as well as emergency department (ED) visits among asthmatic children who had universal access to health care. Newly diagnosed asthmatic children 3-4 years of age were followed up for a period of 6 years. Information on hospitalization and ED visits was obtained by interviewing parents. Socioeconomic status (SES) was measured by paternal occupation, race, type of dwelling, and an index of crowding. After adjusting for asthma severity, logistic regression analysis showed that children with fathers in the economically least advantaged occupations were more likely to be hospitalized due to their asthma [father's occupation group 3 (FOG3), odds ratio (OR)=2.1, 95% confidence interval (95% CI)=0.2-19.8; father's occupation group 4 (FOG4), OR=13.9, 95% CI=1.1-181.4]. The probability of emergency department visits was not significantly different according to the studied variables. Emergency department visits were not influenced by SES variables, probably due to the absence offinancial barriers to access health care. However, SES differences in hospitalization may suggest differential management and/or treatment practices according to socioeconomic status at the emergency departments.

Abstract
BACKGROUND Studies of the use of anti-inflammatory asthma therapy have been limited to selected populations or have been unable to assess the appropriateness of therapy for individuals. OBJECTIVE We sought to describe the current use of asthma medication in the United States population and to examine the influence of symptoms and sociodemographics on medication use. METHODS This study was based on a cross-sectional, national, random-digit-dial household telephone survey in 1998 designed to identify adult patients and parents of children with current asthma. Respondents were classified as having current asthma if they had a physician's diagnosis of asthma and were either taking medication for asthma or had asthma symptoms during the past year. RESULTS One or more persons met the study criteria for current asthma in 3273 (7.8%) households in which a screening questionnaire was completed. Of these, 2509 persons (721 children <16 years) with current asthma were interviewed. Current use of anti-inflammatory medication was reported by 507 (20.1%). Of these, most were using inhaled corticosteroids (72.5%), with use of antileukotrienes reported by 11.4% and use of cromolyn-nedocromil reported by 18.6%. Of persons with persistent asthma symptoms in the past month, 26.2% reported current use of some form of anti-inflammatory medication. In bivariate analysis persons reporting lower income, less education, and present unemployment, as well as smokers, were significantly (P <.001) less likely to report current anti-inflammatory use than were other populations. In a multiple regression model nonsmokers and those of white, non-Hispanic ethnicity, as well as persons reporting less asthma control, were more likely to report current anti-inflammatory medication use. CONCLUSION In the United States use of appropriate asthma therapy remains inadequate. Strategies to increase use of anti-inflammatory therapy among patients with asthma are needed. These might include methods to increase access to asthma care for minorities and the socioeconomically disadvantaged.

Abstract
The purpose of this study was to examine relationships between patient- and disease-related variables and health-related quality of life (HQL). This cross-sectional study surveyed adults with asthma enrolled in a managed care organization (MCO). Data were obtained from a mailed questionnaire and the MCO's patient and claims databases. The Asthma Quality of Life Questionnaire (AQLQ) and the SF-36 instruments were used. The behavioral Model of Health Services Utilization was used to characterize independent variables and their relationships to HQL. Independent variables included predisposing (age, gender, education, race, number of comorbidities, years with asthma, social support, health-belief questions); enabling (income, number of metered dose inhaler (MDI) instructors, perceived inconvenience of accessing the physician); and illness level (perceived and symptom-derived asthma severity). Multivariate linear regression models were developed to examine the relationships between the independent variables and the domain and summary scores of the AQLQ and the SF-36. The survey response rate was 63% (n=603). for the AQLQ, symptom-derived severity perceived severity education level, and the health-belief factor Barriers were significant in all five models. Symptom-derived severity had consistently higher standardized regression coefficients than perceived severity Barriers had the highest coefficient in all but the Symptoms domain model. Number of Comorbidities was significant in all eight domain and two summary score SF-36 models. Symptom-derived and/or perceived severity were also significant in all but the Mental Health domain model. Other frequently significant variables included the health-belief factor Barriers and Yearly Household Income. When assessing HQL of a population, such as this group of patients with asthma, one must consider patient and disease variables that may influence the results.

Abstract
The relationship between socioeconomic variables and the health-related quality of life (HQL) of children with asthma and their caregivers was examined. The Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and Pediatric Asthma Caregivers Quality of Life Questionnaire (PACQLQ) were administered to 99 pediatric asthmatic patients and caregivers in two specialty clinics. Sociodemographic data was obtained from medical records and additional questions. The relationship between sociodemographic variables and HQL was determined using multiple linear regression. The mean patient age was 12.6+/-2.1 years, more were male and from a minority race. The mean age of caregivers was 41.2+/-8.5 years; most were female and were fom a minority race. Patients tended to rate their asthma severity as mild to moderate, while caregivers tended to rate patients in the moderate to severe category. Based on prescribed medications, most patients had mild to moderate asthma. Household income was consistently associated with patient-perceived HQL. Less consistent associations were seen with other variables. Household income and the caregiver's perception of asthma severity were associated with all caregiver HQL domains. It was concluded that household income was most consistently associated with the HQL of asthmatic pediatric patients and their caregivers.

Abstract
BACKGROUND Asthma is a disease with physical symptoms that can impair a person's functioning to the point of interfering with school, work, and social activities. OBJECTIVE Describe how disease (asthma) and patient characteristics affect perceived work performance and absenteeism. METHODS Using a cross-sectional study design, 369 adults with asthma from a managed care organization responded to a mailed questionnaire which included a perceived work performance scale (WPS) and an item assessing absenteeism. Analysis consisted of psychometric testing of the scale (internal consistency and construct validity); trend observation of influence of perceived and symptom-derived severity on WPS and absenteeism distribution; and regression analysis to examine the relationship between patient/disease characteristics and the work-related outcomes. RESULTS The mean WPS score was 88.0 +/- 16.2 (of a possible 100), with a Cronbach's alpha of 0.79. Most respondents (84.7%) did not miss any work in the previous 4 weeks. WPS scores declined and the percentage of respondent absenteeism increased as perceived and symptom-derived severity worsened. The regression model for WPS produced an adjusted R2 of 0.32 and included the number of other illnesses, health beliefs, race, income, and perceived and symptom-derived asthma severity. The regression model for absenteeism included number of other illnesses, race, health beliefs, and symptom-derived severity. Perceived work performance and absenteeism are outcomes measures that are distinctive and complementary. CONCLUSIONS Disease severity, race, income, and health beliefs also contribute and should be considered in health services research related to asthma.

Abstract
BACKGROUND The morbidity and mortality from asthma have markedly increased since the late 1970s. The hospitalization rate, an important marker of asthma severity, remains substantial. METHODS In adults with health care access, we prospectively studied 242 with asthma, aged 18-50 years, recruited from a random sample of allergy and pulmonary physician practices in Northern California to identify risk factors for subsequent hospitalization. RESULTS Thirty-nine subjects (16%) reported hospitalization for asthma during the 18-month follow-up period. On controlling for asthma severity in multiple logistic regression analysis, non-white race (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.1-8.8) and lower income (OR, 1.1 per $10,000 decrement; 95% CI, 0.9-1.3) were associated with a higher risk of asthma hospitalization. The severity-of-asthma score (OR, 3.4 per 5 points; 95%, CI 1.7-6.8) and recent asthma hospitalization (OR, 8.3; 95%, CI, 2.1-33.4) were also related to higher risk, after adjusting for demographic characteristics. Reliance on emergency department services for urgent asthma care was also associated with a greater likelihood of hospitalization (OR, 3.2; 95% CI, 1.0-9.8). In multivariate analysis not controlling for asthma severity, low income was even more strongly related to hospitalization (OR, 1.2 per $10,000 decrement; 95% CI, 1.02-1.4). CONCLUSION In adult asthmatics with access to health care, non-white race, low income, and greater asthma severity were associated with a higher risk of hospitalization. Targeted interventions applied to high-risk asthma patients may reduce asthma morbidity and mortality.

Abstract
OBJECTIVES To identify factors associated with asthma patients' perceptions of the propensity of pulmonologists to involve them in treatment decision-making, and its association with asthma outcomes. DESIGN Cross-sectional observational study performed from June 1995 to December 1997. SETTING Pulmonary unit of a university teaching hospital. PATIENTS Adult patients with asthma (n = 128). MEASUREMENTS AND RESULTS By patient self-report, mean physician's participatory decision-making (PDM) style score was 72 (maximum 100, 95% CI 65, 79). PDM scores were significantly correlated (P < .0001) with the duration of clinic visits (r = .63), patient satisfaction (r = .53), duration of tenure of doctor-patient relationship (r = .37), and formal education (r = .22, P = .023). Significantly higher PDM style scores were reported when visits lasted longer than 20 minutes and when a patient had a >6-month relationship with a particular doctor. PDM scores were also significantly correlated with possession of a written asthma action plan (r = .54, P < .0001), days affected by asthma (r = .36, P = .0001), asthma symptoms (r = .23, P = .017), and preferences for autonomy in asthma management decisions (r = .28, P = .0035). Those with PDM scores <50 reported significantly lower quality of life for all domains of a disease-specific instrument and the Short-Form 36 health survey version 1.0. In multiple regression analysis, PDM style was associated with the length of the office visit and the duration of tenure of the physician-patient relationship (R2 = 0.47, P = .0009). The adjusted odds ratio, per standard deviation decrease in PDM scores, for an asthma hospitalization was 2.0 (95% CI 1.2, 3.2) and for rehospitalization was 2.5 (95% CI 1.2, 4.2). CONCLUSIONS Patients' report of their physician's PDM style is significantly associated with health-related quality of life, work disability, and recent need for acute health services. Organizational factors, specifically longer visits and more time seeing a particular physician, are independently associated with more participatory visits. This has significant policy implications for asthma management.

Abstract
We determined access and satisfaction of 2,598 recipients of Virginia's Medicaid program, comparing its health maintenance organizations (HMOs) to its primary care case management (PCCM) program. Positive responses were summed as sub-domains either of access, satisfaction, or of utilization, and adjusted odds ratios were calculated for HMO (vs. PCCM) sub-domain scores. The response rate was 47 per cent. We found few significant differences in perceived access, satisfaction, and utilization. Both HMO adults and children more often perceived good geographic access (adults, OR, [CI] = 1.50, [1.04-2.16]; children, OR, [CI] = 1.773 [1.158, 2.716]). But HMO patients less often reported good after-hours access (adults, OR, [CI] = 0.527 [0.335, 0.830]; children, OR, [CI] = 0.583 [0.380, 0.894]). Among all patients reporting poorer function, HMO patients more often reported good general and preventive care (OR, [CI] = 2.735 [1.138, 6.575]). We found some differences between Medicaid HMO versus PCCM recipients' reported access, satisfaction, and utilization, but were unable to validate concerns about access and quality under more restrictive forms of Medicaid managed care.

Abstract
BACKGROUND Acquisition of the Helicobacter pylori infection usually occurs in childhood. The prevalence of infection differs among ethnic groups and in adults is inversely related to the socioeconomic status of the individual's family during childhood. This study investigates the seroprevalence of H. pylori infection in children of different ethnic groups in relation to socioeconomic class and investigates the prevalence of acute H. pylori infection among children who have had recent onset of abdominal pain. METHODS Serum samples were collected from 797 children, aged 6 months to 18 years, of various socioeconomic and ethnic backgrounds, at a large urban children's hospital. H. pylori status was determined by an anti-H. pylori immunoglobulin (Ig)G enzyme-linked immunosorbent assay (ELISA) validated for pediatric use. To determine the prevalence of acute H. pylori infection, children brought to the emergency center with abdominal symptoms without diarrhea and overt signs of acute abdomen were evaluated with both serology and the 13C-urea breath test. Acute H. pylori was defined as a positive 13C-urea breath test result and negative IgG serology for H. pylori. RESULTS The overall seroprevalence of H. pylori was 12.2% and increased with age (e.g., 8.3% at 6-11.9 months and 17.9% at 13 years). The prevalence was inversely related to socioeconomic status (6.6%, moderate to high vs. 15%, low socioeconomic status). The difference in seroprevalence among blacks (16.8%), Hispanics (13.3%), and whites (8.3%; P < 0.01) could be accounted for by differences in socioeconomic status. Eighteen percent of children who were evaluated at the emergency center for recent-onset abdominal pain had acute H. pylori infections. CONCLUSIONS Socioeconomic status, not ethnic group, is the more important risk factor for acquisition of H. pylori infection during childhood. Acute H. pylori infection was a relatively common cause of recent-onset, nonsurgical abdominal pain.

Abstract
Medical schools' affirmative action policies traditionally focus on race and give relatively little consideration to applicants' socioeconomic status or "social class." However, recent challenges to affirmative action have raised the prospect of using social class, instead of race, as the basis for preferential admissions decisions in an effort to maintain or increase student diversity. This article reviews the evidence for class-based affirmative action in medicine and concludes that it might be an effective supplement to, rather than a replacement for, race-based affirmative action. The authors consider the research literature on (1) medical students' socioeconomic background, (2) the impact of social class on medical treatment and physician-patient communication, and (3) correlations between physicians' socioeconomic origins and their service patterns to the disadvantaged. They also reference sociological literature on distinctions between race and class and Americans' discomfort with "social class."

Abstract
STUDY OBJECTIVE The prevalence of respiratory symptoms has been found in some studies to vary with social class. One explanation of this link may be the effect of exposure to cigarette smoke. To investigate this, the relation between social class, smoking and respiratory symptoms was explored in a population based survey. DESIGN A cross sectional survey using a validated questionnaire. SETTING Two general practices in Staffordshire, United Kingdom. PATIENTS A random sample of 4237 patients aged 16 and over from two general practices in Staffordshire were mailed a questionnaire enquiring about respiratory symptoms and their severity. MAIN RESULTS The severity of respiratory symptoms increased with increasing exposure to cigarette smoke and was greater among manual social classes. Current smokers (odds ratio (OR) = 2.9, 95% confidence limits (CI) 2.3, 3.6), past smokers (OR = 1.5, 95% CI 1.2, 1.8) and passive smokers (OR = 1.4, 95% CI 1.0, 1.8) were more likely to report the more severe respiratory symptoms compared with non-smokers. Responders from social class V (OR = 2.4, 95% CI 1.3, 4. 4) were more likely to report the more severe respiratory symptoms compared with social class I, as were responders from social classes IIIM (OR = 1.3, 95% CI 0.9, 1.9) and IV (OR = 1.4, 95% CI 0.9, 2.1). These effects were independent of each other. CONCLUSIONS This study has shown that social class is linked to the severity of respiratory symptoms, independently of smoking. Although the need to reduce and quit smoking in manual class households remains a crucial preventive issue, other mechanisms by which social class differences may influence symptom occurrence and severity need to be explored.

Abstract
INTRODUCTION Little is known of the approaches of United States hospitals to the management of persons with asthma. The purpose of this study is to characterize the extent to which hospitals within a large community have implemented various types of asthma-specific health-care delivery processes. METHODS A cross-sectional, self-administered survey was mailed to a "key informant" in asthma care at each of the hospitals in the Chicago area. The survey instrument covered the following content areas: asthma-related inpatient services, asthma-related outpatient services, selected asthma-related quality improvement activities, and asthma-related community outreach. The survey was administered between August 1996 and January 1997. RESULTS Data were collected from respondents at 59 of the 89 eligible hospitals, yielding a response rate of 66.3%. Of the responding hospitals, 42.4% indicated they had clinical practice guidelines for inpatient asthma management, and 37.3% reported using critical pathways. Four selected aspects of bedside care were also explored. All of the responding hospitals reported routine provision of nebulization therapy at the bedside, and nearly all routinely obtained peak flow measurements (96.6%). In the area of patient instruction, 93.2% provided bedside evaluation of proper inhaler technique, and 86.4% routinely provided instruction on the use of peak flowmeters. Only 54.0% of the hospitals reported routinely administering some type of asthma education program prior to discharge. The hospitals with clinical practice guidelines in place were also more likely to have critical pathways (p < 0.01); to have asthma-specific ICU policies/guidelines/critical pathways (p < 0.01); to provide bedside instruction on the use of peak flowmeters (p < 0.01); to provide an asthma education (p < 0.01) prior to discharge; and to conduct utilization review. Very few hospitals indicated that they had community outreach programs for asthma care. CONCLUSION The results of this survey suggest that among Chicago-area hospitals appropriate bedside care for persons with asthma is provided, but there are large variations in other types of asthma services and programs. The hospitals that have adopted asthma clinical practice guidelines are more likely to have other asthma-specific quality improvement activities than hospitals without guidelines. This relationship between use of guidelines and quality of services needs further exploration, as it may prove to be an important marker for hospitals with staff that are interested in improving asthma care.

Abstract
Lay definitions of asthma were elicited through a single open-ended question from a population-based sample of mostly Puerto Rican, inner-city residents in Buffalo, New York. One hundred fifty-five household responses to the question, "What do you think asthma is?" were analyzed qualitatively using the editing approach. Five common codes emerged in order of significance: "symptoms," "disease," "triggers," "threat," and "coping." Overall, expressions of illness reflected a largely symptomatic perception of asthma regardless of asthma status. Perceptions of "disease" increased with higher level of education. Patients' definitions of illness should be considered to help reduce interpersonal barriers to asthma care.

Abstract
The objective of this study was to determine whether racial differences in patterns of asthma care persist in a healthcare environment when financial barriers to health care are minimized. The study cohort consisted of African-American (AA) and Caucasian (C) patients, 18-50 years old, enrolled in a large HMO and hospitalized for asthma in 1993-1995. Baseline and 1-year follow-up data were collected from the HMO computerized database. Of the 193 patients in the cohort, 124 (65.3%) were AA and 67 (34.7%) were C. AAs were younger (mean = 36.2, SD = 9.9) than Cs (mean = 39.4, SD = 9.1), had a lower median household income, and made more asthma-related emergency department (ED) visits (45.2%) than Cs (22.4%) during the 1 year after the initial hospitalization (all p values <0.001). During the same time period, Cs made more asthma-related primary care (70.2%) and allergy/pulmonary visits (38.8%) than AAs (47.6% and 27%, respectively). Although there were no significant racial differences in the rehospitalization rate, AA Medicaid contract patients (32%) had more rehospitalizations for asthma than AA regular contract patients (15.8%). These differential patterns in the use of asthma-related healthcare in this study indicate that the provision of health insurance alone is not sufficient to promote optimal levels of asthma management by all beneficiaries. Asthma education programs targeted for low-income AA patients may improve inappropriate healthcare use patterns.

Abstract
Racial and ethnic minorities of low socioeconomic status residing in urban environments currently referred to as inner cities appear to represent a population that is disproportionately at high risk for asthma morbidity and mortality. Epidemiologic studies suggest that key risk factors contributing to asthma morbidity within the inner city include social demography, the physical environment (indoor and outdoor), and health care access and quality. This epidemiologic literature has helped to define opportunities for successful intervention strategies in these high-risk populations. Studies of the effectiveness of community-based and health system-based interventions with specific focus on inner-city populations are beginning to emerge in the literature.

Abstract
Surveys of women's perceptions of quality and satisfaction with healthcare are widely administered and reported, yet no similar studies of women physicians' perceptions have been conducted. We analyzed related data from the Women Physicians' Health Study, a nationally representative sample of 4501 U.S. women physicians. Among U.S. women physicians, 39% thought the healthcare they personally received was excellent, 37% considered it to be very good, 19% good, 4% fair, and 1% judged their healthcare to be poor quality. Physicians may be especially rigorous judges of healthcare quality, and their assessment of the healthcare they receive is generally positive, an encouraging finding. However, as physicians are highly qualified to assess and potentially obtain high-quality healthcare and as they generally did not judge the care they received to be excellent, the findings also suggest that there are opportunities for improvements in the quality of women's healthcare.

Abstract
Although a substantial body of epidemiological and economic literature on asthma exists, relatively little is known about the impact of asthma on health-related quality of life (HRQL). The purpose of this review was to synthesize results from recent studies, profile the factors influencing HRQL in asthmatics, discuss the impact of treatment on HRQL outcomes, and offer recommendations for further research. The results of this review support the premise that asthma can adversely affect the physical, psychological, and social domains of HRQL. Published data suggest that females, those from lower socioeconomic groups, and ethnic minorities experience poorer quality of life as a result of their asthma symptoms. Results of published clinical trials indicate treatment regimens can have a significant impact on HRQL outcomes. Pharmacological interventions appear to effect change primarily in the physical domain and behavioral interventions lead to improvements in both physical and psychosocial domains. Future research should focus on precise a priori delineation of research hypotheses, including the selection of primary and secondary endpoints, the clarification and consistent application of criteria for defining asthma severity, thoughtful selection of HRQL instruments appropriate for the research hypotheses and target population, and careful delineation of clinically meaningful change scores of asthma-specific outcome measures.

Abstract
STUDY OBJECTIVES To determine the relationship of literacy to asthma knowledge and ability to use a metered-dose inhaler (MDI) among patients with asthma. DESIGN Cross-sectional survey. SETTING Emergency department and asthma clinic at an urban public hospital. PATIENTS Convenience sample of 273 patients presenting to the emergency department for an asthma exacerbation and 210 patients presenting to a specialized asthma clinic for routine care. INTERVENTIONS Measurement of literacy with the Rapid Estimate of Adult Literacy in Medicine, asthma knowledge (20 question oral test), and demonstration of MDI technique (six-item assessment). MEASUREMENTS AND RESULTS Only 27% of patients read at the high-school level, although two thirds reported being high-school graduates; 33% read at the seventh- to eighth-grade level, 27% at the fourth- to sixth-grade level, and 13% at or below the third-grade level. Mean asthma knowledge scores (+/-SD) were directly related to reading levels: 15.1+/-2.5, 13.9+/-2.5, 13.4+/-2.8, 11.9+/-2.5, respectively (p < 0.01). Patient reading level was the strongest predictor of asthma knowledge score in multivariate analysis. Poor MDI technique (< or =3 correct steps) was found in 89% of patients reading at less than the third-grade level compared with 48% of patients reading at the high-school level. In multivariate regression analyses, reading level was the strongest predictor of MDI technique. CONCLUSIONS Inadequate literacy was common and strongly correlated with poorer knowledge of asthma and improper MDI use.

Abstract
The purpose of this study was to evaluate the reliability and validity of the Asthma Quality of Life Questionnaire (AQLQ) in a population-based sample of low-income adults with asthma. A total of 112 subjects (46 African American, 66 Caucasian; mean age = 33 +/- 9 yr; 26% male) were recruited from the Baltimore County, Maryland and Atlanta, Georgia metropolitan areas. Internal consistency reliability (Cronbach's alpha) was high for the overall scale (0. 96); 2-wk reproducibility (intraclass correlation, ICC) was 0.82 (n = 38). Overall score was significantly correlated with FEV1 percentage of predicted (r = 0.20), and the Asthma Disease Severity Scale (r = -0.38). Correlations between overall score and the SF-36 Physical Component Summary (r = 0.49), SF-36 Mental Component Summary (r = 0.37), Cantril's Ladder (r = 0.23), and the Health Utilities Index (r = 0.22) supported the validity of the AQLQ in this sample. Comparison of reliability and validity estimates across racial groups found few substantive differences. Internal consistency, reproducibility, and validity estimates found in this sample were consistent with those of a reliable and valid measure and were comparable to those found in other populations. These results suggest the AQLQ is a useful indicator of health- related quality of life in low-income asthmatics.

Abstract
Poor adherence to medication regimens may be contributing to the recent increase in asthma morbidity and mortality. We examined patient characteristics that may influence adherence to twice-daily inhaled steroid regimens. Fifty adults with moderate to severe asthma completed questionnaires examining sociodemographics, asthma severity, and health locus of control. Adherence was electronically monitored for 42 d. Following monitoring, patients' understanding of asthma pathophysiology and the function of inhaled corticosteroids were assessed. Patient beliefs about the effectiveness and convenience of these medications, and their perception of communications with their clinician were measured. Mean adherence was 63% +/- 38%; 54% of subjects recorded at least 70% of the prescribed number of inhaled-steroid actuations. Factors associated with poor adherence were less than 12 yr of formal education (p < 0. 001), poor patient-clinician communication (p < 0.001), household income less than $20,000 (p = 0.002), Spanish as primary language (p = 0.005), and minority status (p = 0.007). In a multiple logistic regression analysis, less than 12 yr of formal education (OR: 6.72; CI: 1.10 to 41.0) and poor patient-clinician communication (OR: 1.2; CI: 1.01 to 1.55) were independently associated with poor adherence. These results emphasize the importance of socioeconomic status and adequate patient-clinician communication for adherence to inhaled-steroid schedules.

Abstract
The proportion of the United States population without health insurance continues to grow. How will this affect the health of the nation? Prior research suggests that the uninsured are at risk for poor health outcomes. They use fewer medical services and have higher mortality rates than do insured persons. The episodic nature of uninsurance and its prevalence among disadvantaged groups makes it difficult to ascertain the health effects of uninsurance. The goal of this review is to assist researchers and policy makers in choosing methodologies to assess the effects of uninsurance. It provides a compendium of methods that have been used to examine the health consequences of uninsurance, the populations in which these methods have been used, and the strengths and weaknesses of different approaches. The review highlights the need for more longitudinal studies that focus on community-based samples of the uninsured.

Abstract
STUDY OBJECTIVES To explicate the interrelationship between asthma hospitalization and race/ethnicity and income. DESIGN Small area ecologic analysis using census and administrative data. SETTING AND PARTICIPANTS All asthma hospitalizations in California were identified using the 1993 California Hospital Discharge file. Small area analyses of Los Angeles (LA) were compared with published rates in New York City (NYC). RESULTS In 1993, the age-adjusted asthma hospitalization rate in California for nonelderly blacks was 42.5/10,000-approximately four times higher than other populations. Black rates remained fourfold higher after stratification by age, income, and urbanicity. Multivariate analyses suggest that the association between black race and asthma hospitalization is independent of income. Regardless of race, children and persons living in poverty were at increased risk for asthma hospitalization. Urbanicity was not a predictor for asthma hospitalization. Overall, asthma hospitalization rates in NYC were 2.8 times higher compared with rates in LA; while rates were similar among blacks (60 vs 40/10,000, respectively), Puerto Rican Hispanics in NYC had dramatically higher rates compared with Mexican Hispanics in LA (63 vs 14/10,000, respectively). CONCLUSIONS After controlling for socioeconomic status, notable differences in asthma hospitalization by race and ethnicity persist. The reasons for the significantly elevated risk of asthma morbidity among blacks remain unclear.
