The Contribution of First-name Information to the Accuracy of Racial-and-Ethnic Imputations Varies by Sex and Race-and-Ethnicity Among Medicare Beneficiaries
BACKGROUND: Data on race-and-ethnicity that are needed to measure health equity are often limited or missing. The importance of first name and sex in predicting race-and-ethnicity is not well understood. OBJECTIVE: The objective of this study was to compare the contribution of first-name information to the accuracy of basic and more complex racial-and-ethnic imputations that incorporate surname information. RESEARCH DESIGN: We imputed race-and-et…

What Role Does Efficiency Play in Understanding the Relationship Between Cost and Quality in Physician Organizations
BACKGROUND: The belief that there is inefficiency, or the potential to improve patient health at current levels of spending, is driving the push for greater value in health care. Previous studies demonstrate overuse of a narrow set of services, suggesting provider inefficiency, but existing studies neither quantify inefficiency more broadly nor assess its variation across physician organizations (POs). DATA AND METHODS: We used data on quality of…
Evaluation of a Center of Excellence Program for Spine Surgery
BACKGROUND: The Centers for Medicare and Medicaid Services and many private health plans are encouraging patients to seek orthopedic care at hospitals designated as centers of excellence. No evaluations have been conducted to compare patient outcomes and costs at centers of excellence versus other hospitals. The objective of our study was to assess whether hospitals designated as spine surgery centers of excellence by a group of over 25 health pl…
Evaluation of Centers of Excellence Program for Knee and Hip Replacement
BACKGROUND: Medicare and private plans are encouraging individuals to seek care at hospitals that are designated as centers of excellence. Few evaluations of such programs have been conducted. This study examines a large national initiative that designated hospitals as centers of excellence for knee and hip replacement. OBJECTIVE: Comparison of outcomes and costs associated with knee and hip replacement at designated hospitals and other hospitals…
Impact of Socioeconomic Adjustment on Physicians’ Relative Cost of Care
BACKGROUND: Ongoing efforts to profile physicians on their relative cost of care have been criticized because they do not account for differences in patients' socioeconomic status (SES). The importance of SES adjustment has not been explored in cost-profiling applications that measure costs using an episode of care framework. OBJECTIVES: We assessed the relationship between SES and episode costs and the impact of adjusting for SES on physicians' …
Impact of Physician–Patient Discussions on Patient Satisfaction
BACKGROUND: When 2 treatment choices (ie, mastectomy vs. breast conserving therapy) show no difference in a primary clinical outcome (ie, survival), patient satisfaction becomes an important marker of the quality of care received. OBJECTIVES: To assess the impact of physician-patient discussion of primary surgical treatment outcomes on patients' satisfaction with medical care (MC) among women with incident breast cancer (BC). METHOD: We used self…
Patient Centered Experiences in Breast Cancer
BACKGROUND: Among breast cancer patients, tamoxifen use is associated with reduced risk of disease relapse and death, but it is often difficult for women to sustain therapy during the 5 years required to obtain maximum benefit. OBJECTIVES: We sought to examine the influence of patient-centered care activities on ongoing tamoxifen use 4 years after initiation, we examined key components of patient-centered care and rates of ongoing tamoxifen. METH…
What is the Concordance Between the Medical Record and Patient Self-Report as Data Sources for Ambulatory Care
BACKGROUND: The validity of quality of care assessments relies upon data quality, yet little is known about the relative completeness and validity of data sources for evaluating the quality of care. OBJECTIVES: We evaluated concordance between ambulatory medical record and patient survey data. Levels of concordance, variations by type of item, sources of disagreement between data sources, and implications for quality of care assessment efforts ar…
Use of Preventive Services by Men Enrolled in Medicare+Choice Plans
Objectives. We examined the effect of demographic and socioeconomic factors on use of preventive services (prostate-specific antigen testing, colorectal cancer screening, and influenza vaccination) among elderly men enrolled in 2 Medicare+Choice health plans. Methods. Data were derived from administrative files and a survey of 1915 male enrollees. We used multivariate logistic regression to assess the effects of enrollee characteristics on preven…
User Control Of Isarithmic Mapping
Cartographers modify isarithmic maps to improve aesthetics and to reduce map error. Bayesian statisticians incorporate prior knowledge into their scientific enquiry, but insist on being explicit about their interventions. This paper proposes that cartographers should adopt a similar explicitness and to be prepared to modify original data. Existing computer algorithms allow for many such manipulations. Three additional interventions are suggested …
