Beta-blockers as single-agent therapy for hypertension and the risk of mortality among patients with chronic obstructive pulmonary disease.

PURPOSE: To assess the association between the type of antihypertensive medication and all-cause mortality among patients with chronic obstructive pulmonary disease (COPD). METHODS: The cohort comprised 1966 patients (mean [+/- SD] age, 65.8 +/- 10.7 years) enrolled in general internal medicine clinics at seven Veterans Affairs medical centers between December 1996 and October 1999. Patients had a diagnosis of both COPD and hypertension and were receiving single-agent antihypertensive therapy. RESULTS: Compared with calcium channel blockers, beta-blockers were associated with a decrease in mortality from any cause after adjusting for propensity for having been prescribed a beta-blocker (hazard ratio = 0.57; 95% confidence interval: 0.33 to 0.89). The association was similar when beta-blockers were compared with all other antihypertensive medications, and the decreased risk of mortality was apparent among patients with pre-existing cardiac disease. Restriction of analyses to long-acting calcium channel blockers or to patients who used beta-agonists did not affect the point estimates. Exposure to the remaining classes of antihypertensive agents was not associated with mortality. CONCLUSION: Beta-blockers may have beneficial effects in patients who have COPD, pre-existing cardiac disease, and hypertension. Beta-blockers may not be contraindicated among patients with COPD.

Predictors of urinary tract infection after menopause: a prospective study.

PURPOSE: To describe the incidence of and risk factors for acute cystitis among nondiabetic and diabetic postmenopausal women. METHODS: We conducted a population-based, prospective cohort study of 1017 postmenopausal women, aged 55 to 75 years, who were enrolled in a health maintenance organization and followed for 2 years. A wide range of behavioral and physiologic exposures were assessed at baseline interview and follow-up clinic visits; the main outcome measure was microbiologically confirmed acute symptomatic cystitis. Follow-up was 87% at 12 months and 81% at 24 months. RESULTS: During 1773 person-years of follow-up, 138 symptomatic urinary tract infections occurred (incidence, 0.07 per person-year). Independent predictors of infection included insulin-treated diabetes (hazard ratio [HR] = 3.4; 95% confidence interval [CI]: 1.7 to 7.0) and a lifetime history of urinary tract infection (HR for six or more infections = 6.9; 95% CI: 3.5 to 13.6). Borderline associations included a history of vaginal estrogen cream use in the last month (HR = 1.8; 95% CI: 1.0 to 3.4), a history of kidney stones (HR = 1.9; 95% CI: 1.0 to 3.7), and asymptomatic bacteriuria at baseline (HR = 1.8; 95% CI: 0.9 to 3.5). Sexual activity, urinary incontinence, parity, postcoital urination, vaginal dryness, use of cranberry juice, vaginal bacterial flora, and postvoid residual bladder volume were not associated with incident acute cystitis after multivariable adjustment. CONCLUSION: Insulin-treated diabetes is a potentially modifiable risk factor for incident acute cystitis among postmenopausal women, whereas a lifetime history of urinary tract infection was the strongest predictor. Use of oral or vaginal estrogen was not protective, and a wide range of behavioral and physiologic factors was not associated with acute cystitis episodes in this generally healthy sample.

Association of body weight with condition-specific quality of life in male veterans.

PURPOSE: We hypothesized that obese adults with coronary heart disease, obstructive lung disease, or depression would report greater impairments in health-related quality of life owing to their angina, dyspnea, or depressive symptoms as compared with persons with normal body weight. METHODS: We analyzed cross-sectional data from the Ambulatory Care Quality Improvement Project, a multicenter study of veterans enrolled in general internal medicine clinics. Health-related quality of life was assessed using the Medical Outcomes Study Short Form-36, the Seattle Angina Questionnaire, the Seattle Obstructive Lung Disease Questionnaire, and the Hopkins Symptom Checklist for Depression. RESULTS: Compared with patients of normal weight (body mass index: 18.5 to 24.9 kg/m2), underweight patients (body mass index <18.5 kg/m2) reported health-related quality-of-life scores that were at least 5% lower (worse) in all 15 quality-of-life domains examined. Patients with class III obesity (body mass index > or =40 kg/m2) reported quality-of-life scores that were at least 5% lower than those of normal weight patients in eight domains. Scores of overweight patients (body mass index: 25 to 29.9 kg/m2) were higher (better) than those of normal weight patients in 11 domains. CONCLUSION: Body mass index was strongly associated with generic- and condition-specific health-related quality of life. Our results suggest that, when considering health-related quality-of-life outcomes among veterans, the optimal body mass index may be above the "normal" range. Further research should test the validity of the 1998 National Institutes of Health body mass index categories as predictors of health outcomes among veterans.

Primary care management of chronic stable angina and asymptomatic suspected or known coronary artery disease: a clinical practice guideline from the American College of Physicians.

In 1999, the American College of Physicians (ACP), then the American College of Physicians-American Society of Internal Medicine, and the American College of Cardiology/American Heart Association (ACC/AHA) developed joint guidelines on the management of patients with chronic stable angina. The ACC/AHA then published an updated guideline in 2002, which ACP recognized as a scientifically valid review of the evidence and background paper. This ACP guideline summarizes the recommendations of the 2002 ACC/AHA updated guideline and underscores the recommendations most likely to be important to physicians seeing patients in the primary care setting. This guideline is the second of 2 that provide guidance on the management of patients with chronic stable angina. This document covers treatment and follow-up of symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months. Sections addressing asymptomatic patients are also included. Asymptomatic refers to patients with known or suspected coronary disease based on a history or electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests. A previous guideline covered diagnosis and risk stratification for symptomatic patients who have not had an acute myocardial infarction or revascularization procedure in the previous 6 months and asymptomatic patients with known or suspected coronary disease based on a history or electrocardiographic evidence of previous myocardial infarction, coronary angiography, or abnormal results on noninvasive tests.

Suboptimal pharmacotherapeutic management of chronic stable angina in the primary care setting.

PURPOSE: To assess the adequacy of symptomatic treatment for chronic stable angina among primary care patients who receive care from the Department of Veterans Affairs (VA). METHODS: We conducted a cross-sectional analysis involving 7038 veterans with self-reported coronary heart disease who completed the Seattle Angina Questionnaire and who had made a primary care visit to one of seven VA general internal medicine clinics between May 1997 and January 2000. The main outcome measures included the anginal frequency scale of the questionnaire and receipt of prescriptions for antianginal medication in three classes (beta-blockers, calcium antagonists, and long-acting nitrates). RESULTS: Seventy percent of the patients experienced angina or took sublingual nitroglycerin preparations two or fewer times per week. Of the 30% of patients with more frequent symptoms, 22% were receiving no antianginal medications and 33% were receiving only one class of antianginal medication. Of the patients with frequent angina who were prescribed medications, 18% were taking no medications at the recommended therapeutic dose and 50% were receiving only one class of antianginal medication at the recommended therapeutic dose. CONCLUSION: A substantial proportion of patients with frequent episodes of chronic stable angina appeared to be receiving an inadequate antianginal regimen in terms of number of agents and dosages. While numerous studies have described inadequate treatment of asymptomatic conditions and risk factors, our results suggest similar deficiencies in addressing a serious and eminently treatable symptomatic problem.

Risk factors for urinary tract infections in postmenopausal women.

BACKGROUND: Urinary tract infections (UTI) occur frequently in postmenopausal women and account for substantial morbidity and economic costs. Although extensively studied in younger women and older, debilitated women, the risk factors for UTI among healthy community-dwelling postmenopausal women have not been well described. METHODS: We conducted a population-based, case-control study of women aged between 55 and 75 years enrolled in a large, staff-model health maintenance organization. Cases were identified using computerized laboratory and outpatient records. Controls were randomly selected from the plan's enrollment files. We interviewed subjects regarding their habits, general health, and potential risk factors for UTI. RESULTS: We interviewed 899 study subjects and 911 controls. Sociodemographic characteristics were similar in subjects and controls. Most women were insured and white. Like younger women, postmenopausal women with current UTI were more likely to be sexually active (odds ratio [OR], 1.42; 95% confidence interval [CI], 1.07-1.87) and have a history of UTI (OR, 4.20; 95% CI, 3.25-5.42). Like older debilitated women, study subjects were more likely to have diabetes mellitus (OR, 2.78; 95% CI, 1.78-4.35) and to be incontinent (OR, 1.36; 95% CI, 1.03-1.78). Oral estrogen replacement did not reduce UTI risk. CONCLUSIONS: In this population, the risk factors of healthy community-dwelling postmenopausal women reflect the health status of women as they transition toward old age. Sexual activity, history of UTI, treated diabetes, and incontinence were all associated with a higher risk of UTI. The therapeutic role of oral estrogen remains uncertain. Prospective studies in different patient populations are needed to better understand the risk factors of UTI.

A controlled trial of including symptom data in computer-based care suggestions for managing patients with chronic heart failure.

BACKGROUND: Heart failure is common and associated with considerable morbidity and cost, yet physician adherence to treatment guidelines is suboptimal. We conducted a randomized controlled study to determine if adding symptom information to evidence-based, computer-generated care suggestions would affect treatment decisions among primary care physicians caring for outpatients with heart failure at two Veterans Affairs medical centers. METHODS: Physicians were randomly assigned to receive either care suggestions generated with electronic medical record data and symptom data obtained from questionnaires mailed to patients within 2 weeks of scheduled outpatient visits (intervention group) or suggestions generated with electronic medical record data alone (control group). Patients had to have a diagnosis of heart failure and objective evidence of left ventricular systolic dysfunction. We assessed physician adherence to heart failure guidelines, as well as patients' New York Heart Association (NYHA) class, quality of life, satisfaction with care, hospitalizations, and outpatient visits, at 6 and 12 months after enrollment. RESULTS: Patients in the intervention (n = 355) and control (n = 365) groups were similar at baseline. At 12 months, there were no significant differences in adherence to care suggestions between physicians in the intervention and control groups (33% vs. 30%, P = 0.4). There were also no significant changes in NYHA class (P = 0.1) and quality-of-life measures (P >0.1), as well as no differences in the number of outpatient visits between intervention and control patients (6.7 vs. 7.1 visits, P = 0.48). Intervention patients were more satisfied with their physicians (P = 0.02) and primary care visit (P = 0.02), but had more all-cause hospitalizations at 6 months (1.5 vs. 0.7 hospitalizations, P = 0.0002) and 12 months (2.3 vs. 1.7 hospitalizations, P = 0.05). CONCLUSION: Adding symptom information to computer-generated care suggestions for patients with heart failure did not affect physician treatment decisions or improve patient outcomes.

Effects of sustained audit/feedback on self-reported health status of primary care patients.

PURPOSE: Because limited audit/feedback of health status information has yielded mixed results, we evaluated the effects of a sustained program of audit/feedback on patient health and satisfaction. METHODS: We conducted a group-randomized effectiveness trial in which firms within Veterans Administration general internal medicine clinics served as units of randomization, intervention, and analysis. Respondents to a baseline health inventory were regularly mailed the 36-Item Short Form (SF-36) and, as relevant, questionnaires about six chronic conditions (ischemic heart disease, diabetes, chronic obstructive pulmonary disease, depression, alcohol use, and hypertension) and satisfaction with care. Data were reported to primary providers at individual patient visits and in aggregate during a 2-year period. RESULTS: Baseline forms were mailed to 34,050 patients; of the 22,413 respondents, 15,346 completed and returned follow-up surveys. Over the 2-year study, the difference between intervention and control groups (as measured by difference in average slope) was -0.26 (95% confidence interval [CI]: -0.79 to 0.27; P=0.28) for the SF-36 Physical Component Summary score and -0.53 (95% CI: -1.09 to 0.03; P=0.06) for the SF-36 Mental Component Summary score. No significant differences emerged after adjusting for deaths. There were no significant differences in condition-specific measures or satisfaction between groups after adjustment for provider type, panel size, and number of intervention visits, or after analysis of patients who completed all forms. CONCLUSION: An elaborate, sustained audit/feedback program of general and condition-specific measures of health/satisfaction did not improve outcomes. To be effective, such data probably should be incorporated into a comprehensive chronic disease management program.

Association between chronic heart failure and inhaled beta-2-adrenoceptor agonists.

BACKGROUND: Recent reports suggest an association between beta-agonists and the risk of incident chronic heart failure (CHF). We sought to examine the association between inhaled beta-agonists and risk of incident and nonincident heart failure. METHODS: We performed a nested case-control study within the Ambulatory Care Quality Improvement Project (ACQUIP). Case subjects were defined as having had a hospitalization with a primary discharge diagnosis of CHF. Controls were randomly selected from the ACQUIP cohort. The exposure was the number of beta-agonist canisters filled in the 90 days before an index date. RESULTS: After adjusting for potentially confounding factors, there appeared to be no association between the use of inhaled beta-agonists and the risk of heart failure (1-2 canisters per month, OR 1.3 [95% CI 0.9, 1.8], > or =3 canisters per month, 1.1 [95% CI 0.8, 1.6]). However, among the cohort that had a history of CHF, there appeared to be a dose-response association between the number of inhaled beta-agonists and the risk of hospitalization for chronic heart failure (1-2 canisters per month, adjusted OR 1.8 [95% CI 1.1, 3.0], > or =3 canisters per month, adjusted OR 2.1 [95% CI 1.2, 3.8]). CONCLUSION: beta-Agonists did not appear to be associated with incident heart failure but were associated with risk of CHF hospitalization among those subjects with a previous CHF diagnosis. Although a causal relationship cannot be inferred from these findings, further research is warranted to determine the safety and effectiveness of inhaled beta-agonists for patients with CHF.

Intraindividual change in SF-36 in ambulatory clinic primary care patients predicted mortality and hospitalizations.

OBJECTIVE: We sought to determine whether change in SF-36 scores over time is associated with the risk of adverse outcomes. STUDY DESIGN AND SETTING: 7,702 participants in the Ambulatory Care Quality Improvement Project who completed a baseline and 1-year SF-36. Using logistic regression methods we estimated the 1-year risk of hospitalization and death based on previous 1-year changes in the physical (PCS) and mental (MCS) component summary scores. RESULTS: After adjusting for baseline PCS scores, age, VA hospital site, distance to VA, and comorbidity, a >10-point decrease in PCS score was associated with an increased risk of death (OR 2.3, 95% CI 1.6-3.4) and hospitalization (OR 1.8, 1.4-2.2). An increased risk was also seen with a >10-point decrease in the MCS (OR for death, 1.6, 1.1-2.3; OR for hospitalization 1.5, 1.2-1.8). CONCLUSION: Change in SF-36 PCS and MCS scores is associated with mortality and hospitalizations, and provides important prognostic information over baseline scores alone.

Using alcohol screening results and treatment history to assess the severity of at-risk drinking in Veterans Affairs primary care patients.

BACKGROUND: Primary care providers need practical methods for managing patients who screen positive for at-risk drinking. We evaluated whether scores on brief alcohol screening questionnaires and patient reports of prior alcohol treatment reflect the severity of recent problems due to drinking. METHODS: Veterans Affairs general medicine outpatients who screened positive for at-risk drinking were mailed questionnaires that included the Alcohol Use Disorders Identification Test (AUDIT) and a question about prior alcohol treatment or participation in Alcoholics Anonymous ("previously treated"). AUDIT questions 4 through 10 were used to measure past-year problems due to drinking (PYPD). Cross-sectional analyses compared the prevalence of PYPD and mean Past-Year AUDIT Symptom Scores (0-28 points) among at-risk drinkers with varying scores on the CAGE (0-4) and AUDIT-C (0-12) and varying treatment histories. RESULTS: Of 7861 male at-risk drinkers who completed questionnaires, 33.9% reported PYPD. AUDIT-C scores were more strongly associated with Past-Year AUDIT Symptom Scores than the CAGE (p < 0.0005). The prevalence of PYPD increased from 33% to 46% over the range of positive CAGE scores but from 29% to 77% over the range of positive AUDIT-C scores. Among subgroups of at-risk drinkers with the same screening scores, patients who reported prior treatment were more likely than never-treated at-risk drinkers to report PYPD and had higher mean Past-Year AUDIT Symptom Scores (p < 0.0005). We propose a simple method of risk-stratifying patients using AUDIT-C scores and alcohol treatment histories. CONCLUSIONS: AUDIT-C scores combined with one question about prior alcohol treatment can help estimate the severity of PYPD among male Veterans Affairs outpatients.

The future of general internal medicine. Report and recommendations from the Society of General Internal Medicine (SGIM) Task Force on the Domain of General Internal Medicine.

The Society of General Internal Medicine asked a task force to redefine the domain of general internal medicine. The task force believes that the chaos and dysfunction that characterize today's medical care, and the challenges facing general internal medicine, should spur innovation. These are our recommendations: while remaining true to its core values and competencies, general internal medicine should stay both broad and deep-ranging from uncomplicated primary care to continuous care of patients with multiple, complex, chronic diseases. Postgraduate and continuing education should develop mastery. Wherever they practice, general internists should be able to lead teams and be responsible for the care their teams give, embrace changes in information systems, and aim to provide most of the care their patients require. Current financing of physician services, especially fee-for-service, must be changed to recognize the value of services performed outside the traditional face-to-face visit and give practitioners incentives to improve quality and efficiency, and provide comprehensive, ongoing care. General internal medicine residency training should be reformed to provide both broad and deep medical knowledge, as well as mastery of informatics, management, and team leadership. General internal medicine residents should have options to tailor their final 1 to 2 years to fit their practice goals, often earning a certificate of added qualification (CAQ) in special generalist fields. Research will expand to include practice and operations management, developing more effective shared decision making and transparent medical records, and promoting the close personal connection that both doctors and patients want. We believe these changes constitute a paradigm shift that can benefit patients and the public and reenergize general internal medicine.

Alcohol screening results in elderly male veterans: association with health status and mortality.

OBJECTIVES: To evaluate the association between alcohol screening results and health status or mortality in elderly patients. DESIGN: Cross-sectional and longitudinal cohort studies. SETTING: Primary care clinics at seven Veterans Affairs medical centers. PARTICIPANTS: A total of 16,958 male patients aged 65 and older. MEASUREMENTS: Alcohol screening questionnaires were used to divide patients into four mutually exclusive groups: drinkers who screened negative or positive for problem drinking and nondrinkers (in the previous year) who screened negative or positive for problem drinking. A subset of patients (n=12,491) completed a measure of health status, the Medical Outcomes Study Short Form (SF-36). All-cause mortality was ascertained using Veterans Affairs data over a mean follow-up of 2.8 years. RESULTS: Forty-eight percent of participants reported drinking in the previous year. Half of the drinkers and nondrinkers screened positive for problem drinking. The SF-36 item scores were consistently higher for drinkers than for nondrinkers and for patients who screened negative for problems than for those who screened positive. Similarly, survival was consistently better in drinkers than nondrinkers (mortality hazard ratio (HR)=0.74, 95% confidence interval (CI)=0.68-0.82) and in patients who screened negative for problem drinking than in those who screened positive (mortality HR=0.87, 95% CI=0.80-0.95). Nondrinkers who screened positive for problem drinking had the poorest health status and survival, whereas drinkers who screened negative for problem drinking had the best health status and survival. CONCLUSION: Elderly patients who reported drinking alcohol and those who screened negative for problem drinking had consistently better health status and survival than those who did not drink and those who screened positive.

Alcohol-related advice for Veterans Affairs primary care patients: Who gets it? Who gives it?

OBJECTIVE: Most patients who misuse alcohol do not receive alcohol counseling from their providers. This study evaluated primary care patient and provider characteristics associated with receipt of alcohol-related advice and whether patients were advised to drink less or to abstain. METHOD: Outpatients from seven Veterans Affairs (VA) general medicine clinics were eligible if they screened positive for alcohol misuse, completed the Alcohol Use Disorders Identification Test (AUDIT) and answered questions about alcohol-related treatment and advice. Hierarchical logistic regression was used to evaluate patient and provider characteristics associated with patient reports of alcohol-related advice from a primary care provider in the past year. RESULTS: Among 5191 patients with alcohol misuse in the past year, 1554 (30%) reported receiving alcohol-related advice from their primary care provider during that time. Of patients advised, 73% reported advice to abstain. The likelihood of reporting advice increased as AUDIT scores increased: from 13% of patients with AUDIT scores <8 to 71% of those with scores > or =20. After adjustment for important confounders, measures reflecting the severity of alcohol misuse were most strongly associated with receipt of alcohol-related advice. Adjusted analyses also revealed increased odds of receiving advice among patients who reported liver disease, hypertension, current smoking or continuity of care. No measured provider characteristic was associated with giving advice in the fully adjusted model. CONCLUSIONS: This multisite VA study found that most patients with alcohol misuse did not receive alcohol counseling from a primary care provider. Moreover, providers predominantly offered advice to abstain, and they appeared to focus on patients with the most severe problems due to drinking or medical contraindications to drinking.

Cardiovascular risk factor control among veterans with diabetes: the ambulatory care quality improvement project.

OBJECTIVE: To describe the extent to which hyperglycemia, hypertension, and dyslipidemia are currently detected, treated, and controlled in U.S. veterans with diabetes with and without ischemic heart disease (IHD). RESEARCH DESIGN AND METHODS: A cohort of 3,769 veterans who self-reported diabetes and who received all health care from the Veterans Administration (VA) medical centers were selected from subjects enrolled in the Ambulatory Care Quality Improvement Project, a randomized health services intervention at seven VA primary care clinics. IHD was defined by a self-reported history of myocardial ischemia, infarction, or revascularization. Mean values of HbA(1c), blood pressure, and cholesterol subfractions were collected from computerized laboratory databases. Medication data were collected from computerized pharmacy databases. RESULTS: Mean HbA(1c) and optimal control (HbA(1c) <7%) did not differ for those without and with IHD: 8.1 vs. 8.0%, and 26 vs. 24%, respectively. Veterans with IHD were more likely to have hypertension (73 vs. 64%), to be treated (88 vs. 78%), and to have optimal blood pressure control (19 vs. 10%) compared with veterans without IHD (all P values <0.01). Veterans with IHD were more likely to have dyslipidemia (81 vs. 53%), were equally likely to be treated (54 vs. 50%), and were more likely to have optimal LDL levels (30 vs. 16%) compared with veterans without IHD, all P values <0.01. CONCLUSIONS: Optimal cardiovascular risk factor control was the exception in this cohort of diabetic veterans attending primary care clinics. More aggressive management of cardiovascular risk factors in veterans with diabetes may be warranted, especially among those without prevalent IHD.

Diabetes quality improvement in Department of Veterans Affairs Ambulatory Care Clinics: a group-randomized clinical trial.

OBJECTIVE: To conduct a group-randomized clinical trial to determine whether regular feedback to primary care providers of synthesized information on patients' health, function, and satisfaction would demonstrate improved outcomes for their patients with diabetes. RESEARCH DESIGN AND METHODS: Patients in General Internal Medicine Clinics Department of Veterans Affairs (VA) Medical Centers were randomized into seven intervention or control firms. Patient self-reported information was collected by mail on general health, diabetes, and up to five other chronic conditions. Patients with diabetes received the Seattle Diabetes Questionnaire, the 36-item Medical Outcomes Study short form (SF-36), and a validated patient satisfaction questionnaire at regular intervals. Data from self-report, clinical, pharmacy, and laboratory sources were synthesized into patient-specific feedback reports that intervention providers received before patients' visits. RESULTS: The timely delivery to primary care providers of state-of-the-art patient-feedback reports that identified patient issues and areas for improvement did not result in significant improvements in patient outcomes between the intervention and control firms. CONCLUSIONS: Outcomes in diabetic patients whose providers received synthesized patient data before visits were no better than in those receiving care from control firms. Future studies may benefit from substantial involvement in patients discussing, problem solving, and goal setting in addition to use of timely synthesized patient data.

Inhaled corticosteroids in chronic obstructive pulmonary disease and risk of death and hospitalization: time-dependent analysis.

Observational studies of inhaled corticosteroids in chronic obstructive pulmonary disease (COPD) have shown improved survival whereas randomized trials have not. It has been suggested that this difference may be due to immortal time bias. To investigate this further, we performed a prospective cohort study of patients with COPD, using time-dependent methods to determine whether use of inhaled corticosteroids more than 80% of the time reduced the risk of all-cause mortality and COPD exacerbations. Of 8,033 patients, 2,686 (33%) received inhaled corticosteroids. We did not find a significant reduction in mortality for average inhaled steroid use at either low (hazard ratio [HR], 0.96; 95% confidence interval [CI], 0.69-1.33) or medium/high dose (HR, 0.86; 95% CI, 0.67-1.10). Similarly, recent inhaled corticosteroid use was not associated with a reduction in mortality at low (HR, 0.80; 95% CI, 0.60-1.07) or medium/high doses (HR, 0.88; 95% CI, 0.71-1.09). There was no association between inhaled corticosteroid use and hospitalizations or exacerbations due to COPD. Patients using medium/high-dose inhaled corticosteroids did not have a significantly lower risk of COPD hospitalizations (HR, 0.85; 95% CI, 0.64-1.13) or COPD exacerbations (HR, 1.13; 95% CI, 0.94-1.36). In a time-dependent study of outpatients with COPD, adherence to inhaled corticosteroid use was not associated with a decreased risk of mortality or exacerbations.
