Qualitative Assessment of Washington State Medicaid Health Plan Readiness to Implement Systems-Based Approaches to Colorectal Cancer Screening
Implementation of population-based colorectal cancer screening programs by Medicaid health plans could address colorectal cancer screening disparities. Our objective is to identify facilitators and barriers to implementation of a population-based colorectal cancer screening program by Washington State Medicaid health plans. We conducted semi-structured interviews with leadership from 2 statewide and 3 national Medicaid plans. We organized the int…
Determination of Colonoscopy Indication From Administrative Claims Data
BACKGROUND: Colonoscopy outcomes, such as polyp detection or complication rates, may differ by procedure indication. OBJECTIVES: To develop methods to classify colonoscopy indications from administrative data, facilitating study of colonoscopy quality and outcomes. RESEARCH DESIGN: We linked 14,844 colonoscopy reports from the Clinical Outcomes Research Initiative, a national repository of endoscopic reports, to the corresponding Medicare Carrier…
Quality of Care for Myocardial Infarction in Rural and Urban Hospitals
BACKGROUND: In the mid-1990s, significant gaps existed in the quality of acute myocardial infarction (AMI) care between rural and urban hospitals. Since then, overall AMI care quality has improved. This study uses more recent data to determine whether rural-urban AMI quality gaps have persisted. METHODS: Using inpatient records data for 34,776 Medicare beneficiaries with AMI from 2000-2001, unadjusted and logistic regression analysis compared rec…
Geographic Differences in Use of Home Oxygen for Obstructive Lung Disease
RATIONALE: Home oxygen is the most expensive equipment item that Medicare purchases ($1.7 billion/year). OBJECTIVES: To assess geographic differences in supplemental oxygen use. METHODS: Retrospective cohort analysis of oxygen claims for a 20% random sample of Medicare patients hospitalized for obstructive lung disease in 1999 and alive at the end of 2000. MEASUREMENTS AND MAIN RESULTS: While 33.7% of the 34,916 hospitalized patients used supplem…
Trends in Perinatal and Infant Health Disparities Between Rural American Indians and Alaska Natives and Rural Whites
Objectives. We examined disparities in perinatal care, birth outcomes, and infant health between rural American Indian and Alaska Native (AIAN) persons and rural Whites over time. Methods. We compared perinatal and infant health measures for 217 064 rural AIAN births and 5 032 533 rural non-Hispanic White births. Results. Among American Indians and Alaska Natives, unadjusted rates of inadequate prenatal care (1985–1987, 36.3%; 1995–1997, 26.3%) a…
No Pain, But No Gain? The Disappearance of Angina Hospitalizations, 1992–1999
BACKGROUND: Hospitalization for angina is commonly considered an ambulatory care sensitive hospitalization and used as a measure of access to primary care. OBJECTIVE: To analyze time trends in angina-related hospitalizations and seek possible explanations for an observed, marked decline during 1992 to 1999. RESEARCH DESIGN: We analyzed Medicare claims of SEER-Medicare control subjects for occurrence of angina hospital discharges, using the Agency…
The Contribution of Longitudinal Comorbidity Measurements to Survival Analysis
BACKGROUND: Many clinical and health services research studies are longitudinal, raising questions about how best to use an individual's comorbidity measurements over time to predict survival. OBJECTIVES: To evaluate the performance of different approaches to longitudinal comorbidity measurement in predicting survival, and to examine strategies for addressing the inevitable issue of missing data. RESEARCH DESIGN: Retrospective cohort study using …
Continuity of Care and Cancer Screening Among Health Plan Enrollees
CONTEXT: Although having a usual source of care has been associated with cancer screening, whether there is additional benefit from continuity with a specific physician is uncertain. In addition, little is known about the relationship between continuity of care and receipt of colorectal and prostate cancer screening. METHODS: Subjects were enrolled in a Washington State health plan that operates an integrated delivery system that emphasizes acces…
Differences Among the Elderly in the Treatment Costs of Colorectal Cancer
BACKGROUND: Medical expenditures adjusted for price differences are a barometer of total resources devoted to patient care and thus may reflect treatment differentials. OBJECTIVE: We sought to estimate costs of the surgical and adjuvant treatment phases of colorectal cancer (CRC) care and cost differences by race (African American-white) and other patient characteristics. METHODS: We used the linked Surveillance, Epidemiology, and End Results (SE…
In Search of the Perfect Comorbidity Measure for Use With Administrative Claims Data
BACKGROUND: Numerous measures of comorbidity have been developed for health services research with administrative claims. OBJECTIVE: We sought to compare the performance of 4 claims-based comorbidity measures. RESEARCH DESIGN AND SUBJECTS: We undertook a retrospective cohort study of 5777 Medicare beneficiaries ages 66 and older with stage III colon cancer reported to the Surveillance, Epidemiology, and End Results Program between January 1, 1992…
Perinatal and Infant Health Among Rural and Urban American Indians/Alaska Natives
Objectives. We sought to provide a national profile of rural and urban American Indian/Alaska Native (AI/AN) maternal and infant health. Methods. In this cross-sectional study of all 1989–1991 singleton AI/AN births to US residents, we compared receipt of an inadequate pattern of prenatal care, low birthweight ( Results. Receipt of an inadequate pattern of prenatal care was significantly higher for rural than for urban mothers of AI/AN infants (1…
Linking Physician Characteristics and Medicare Claims Data
BACKGROUND: Increasingly, investigators are using administrative databases to answer research questions requiring physician characteristics information. This article provides a roadmap for investigators who use Medicare data to answer such questions, focusing on use of the Surveillance, Epidemiology, and End Results (SEER)-Medicare files. METHODS: Three data sources that can be linked to identify physician characteristics-Medicare claims, the Uni…
How Well Do Birth Certificates Describe the Pregnancies They Report? The Washington State Experience with Low-Risk Pregnancies
