Inside the Health Disparities Collaboratives
BACKGROUND: Quality improvement collaboratives (QICs) based on the Chronic Care Model (CCM) are widely used models for improving medical care, but there has been little information to date about the specific projects undertaken by participants in these collaboratives and their outcomes. OBJECTIVES: To describe initiatives undertaken by community health centers (CHCs) participating in QICs (the Health Disparities Collaboratives) for asthma, cardio…
Reducing Racial/Ethnic Disparities in Female Breast Cancer
Objectives. We assessed whether population rates of mammography screening, and their changes over time, were associated with improvements in breast cancer stage at diagnosis and whether the strength of this association varied by race/ethnicity. Methods. We analyzed state cancer registry data linked to socioeconomic characteristics of patients’ areas of residence for 1990–1998 time trends in the likelihood of early stage diagnosis. We appended eac…
Examining the Relationship of Patients’ Attitudes and Beliefs With Their Self-Reported Level of Participation in Medical Decision-Making
OBJECTIVE: We applied constructs from the transtheoretical model (TTM) of behavior change to identify modifiable determinants of patient participation in medical decision-making. METHOD: We surveyed a convenience sample of 621 primary care patients at one Boston hospital (response rate 60.6%). With a random half of the sample, we examined the factor structure of a new Patient Attitudes and Beliefs Scale (PABS) that focused on issues about partici…
The Effect of Managed Care Market Share on Appropriate Use of Coronary Angiography among Traditional Medicare Beneficiaries
Evidence suggests that when managed care market share increases in a geographic area, expenditures in Medicare's fee-for-service sector decrease. But it is unclear how expenditure reductions relate to the quality of medical care for traditional Medicare beneficiaries. We estimated how managed care market share varied with the proportion of fee-for-service Medicare beneficiaries who were admitted for acute myocardial infarction (AMI) and underwent…
Understanding Individual and Small Area Variation in the Underuse of Coronary Angiography Following Acute Myocardial Infarction
BACKGROUND: Underuse of coronary angiography is common among patients with acute myocardial infarction (AMI) and the magnitude of underuse varies across geographic areas. OBJECTIVES: To examine the influence of patient demographic, clinical and hospital characteristics on underuse of coronary angiography, and the contribution of these factors to variation in underuse across geographic regions. RESEARCH DESIGN: Cohort study using data from the Coo…
Patient Demographic and Socioeconomic Characteristics in the Seer-Medicare Database
Users of the linked SEER-Medicare database commonly perform analyses that focus on the complex interactions among patient characteristics, cancer treatments, and outcomes. The authors review the source and scope of the patient-specific data elements, with a focus on three domains--demographic characteristics, socioeconomic characteristics, and survival status. They offer some concrete recommendations regarding the use of these data elements. In p…
Validating recommendations for coronary angiography following acute myocardial infarction in the elderly
Identifying a Cohort of Patients With Early-Stage Breast Cancer
BACKGROUND: Hospital discharge data are a potential source of information for quality of care; however, they lack detailed clinical data. OBJECTIVES: To assess the usefulness of hospital discharge data for describing patterns of care. RESEARCH DESIGN: Cohort study comparing hospital discharge data with data collected from medical records and patients. PATIENTS: Women diagnosed with early-stage breast cancer in Massachusetts and Minnesota (1993-19…
Impact of Underuse, Overuse, and Discretionary Use on Geographic Variation in the Use of Coronary Angiography After Acute Myocardial Infarction
BACKGROUND: Geographic variation in the use of medical procedures has been well documented. However, it is not known whether this variation is due to differences in use when procedures are indicated, discretionary, or contraindicated. OBJECTIVES: To examine whether use of coronary angiography after acute myocardial infarction (AMI) according to appropriateness criteria varied across geographic regions and whether underuse, overuse, or discretiona…
The Treating Physician as Active Gatekeeper in the Recruitment of Research Subjects
BACKGROUND: Institutional Review Boards vary in regard to the conditions imposed on investigators concerning contacting potential subjects to participate in health-services research studies. OBJECTIVE: The impact of more active involvement of the treating physician was examined in the approval process for recruiting study subjects. DESIGN: In recruiting subjects for a Massachusetts-based, multihospital (n = 17), health-services research study of …
Discussion of Treatment Options for Early-Stage Breast Cancer
OBJECTIVES: To describe the physicians with whom breast cancer patients discuss treatment options and assess whether discussing surgical options with a medical oncologist is associated with type of surgery and satisfaction. RESEARCH DESIGN: Medical record abstraction and survey. SUBJECTS: Women with early-stage breast cancer numbering 2,426 in two states-Massachusetts, where the rate of breast-conserving surgery is high, and Minnesota, where it i…
The influence of race on approaching families for organ donation and their decision to donate
OBJECTIVES: This study examined whether patients' race was associated with their families' being approached for organ donation and agreeing to donation. METHODS: Logistic regression models were applied to data collected from records at 112 hospitals. RESULTS: The odds that a family of a White patient was approached for donation were nearly twice those for a family of an African American. The odds of donation also differed by race, but the magnitu…

How Consistent Is Patient-Reported Pre-admission Health Status When Collected During and After Hospital Stay
Efforts to establish the effectiveness of medical care or to assess the quality of care rely increasingly on patients' reports of change in their health status. Such efforts typically require measurement of health status before an intervention takes place (i.e., a baseline assessment) and again at a later, clinically meaningful time. The assessment of baseline health status is not always possible before an intervention, and patients often are ask…
The influence of socioeconomic status on change in health status after hospitalization
A Comparison of Pattern Matching Indices
A common problem in multivariate applications is the comparison of pattern matrices obtained from two independent studies. We compared the performance of four pattern matching indices (the coefficient of congruence [c], the s-statistic [s], Pearson's r [r], and kappa [k]) under a variety of experimental conditions. We constructed population pattern matrices by varying (a) saturation or the size of the loadings, (b) sample size, (c) the number of …
Patterns of Change
Patterns of change occurring in a combined cross-sectional and longitudinal (cross-sequential) analysis of 14 variables were investigated in a two-year study of self-change approaches to smoking cessation. Every six months for five rounds, subjects (N = 544) were assessed on 10 change processes, self-efficacy, temptations to smoke, and their decisions weighing the pros and cons of smoking. Subjects were also assessed on which of the following fou…
