BACKGROUND The Surveillance, Epidemiology and End Results (SEER)-Medicare-linked database combines clinical information from population-based cancer registries with claims information from the Medicare program. The use of this database to study cancer screening, treatment, outcomes, and costs has grown in recent years. RESEARCH DESIGN This paper provides(More)
Important comorbidities recorded on outpatient claims in administrative datasets may be missed in analyses when only inpatient care is considered. Using the comorbid conditions identified by Charlson and colleagues, we developed a comorbidity index that incorporates the diagnostic and procedure data contained in Medicare physician (Part B) claims. In the(More)
OBJECTIVE The purpose of this report is to examine (a) gender-specific correlates of colorectal cancer test use using recent national data from 2003 and (b) patterns of colorectal cancer screening by gender and test modality over time. METHODS We analyze data from the 1987, 1992, 1998, 2000, and 2003 National Health Interview Surveys. Our sample consists(More)
BACKGROUND Screening is effective in reducing the incidence and mortality of colorectal cancer. Rates of colorectal cancer test use continue to be low. METHODS The authors analyzed data from the National Health Interview Survey concerning the use of the home-administered fecal occult blood test (FOBT) and sigmoidoscopy/colonoscopy/proctoscopy to estimate(More)
PURPOSE We evaluated (i) how combining comorbid conditions identified from Medicare inpatient or physician claims into a single comorbidity index compared with three other comorbidity indices and (ii) the need for comorbid condition weights that are specific to different cancer sites. METHODS This observational study used the SEER-Medicare linked(More)
BACKGROUND Recommended colorectal cancer (CRC) screening tests for adults ages 50 to 75 years include home fecal occult blood tests (FOBT), sigmoidoscopy with FOBT, and colonoscopy. A newer test, computed tomographic (CT) colonography, has been recommended by some, but not all, national organizations. METHODS We analyzed 2010 National Health Interview(More)
BACKGROUND Medicare claims include codes for chemotherapy administration and specific drugs given, and researchers are increasingly using these data to measure the use of chemotherapy. However, the validity and completeness of these data as a source of information has not been established. OBJECTIVES This analysis is intended to assess the utility of the(More)
BACKGROUND Although use of colonoscopy has increased substantially among elderly Medicare beneficiaries, no one has described colonoscopy-related adverse events in a representative sample of Medicare patients. OBJECTIVE To determine risk for adverse events after outpatient colonoscopy in elderly patients. DESIGN Population-based, matched cohort study.(More)
BACKGROUND Evaluating trends in colorectal cancer (CRC) screening use is critical for understanding screening implementation, and whether population groups targeted for screening are receiving it, consistent with guidelines. This study examines recent national trends in CRC test use, including among vulnerable populations. METHODS We used the 2000, 2003,(More)
BACKGROUND Recent research has supported the use of colorectal cancer (CRC) tests to reduce disease incidence, morbidity, and mortality. A new health survey has provided an opportunity to examine the use of these tests in California's ethnically diverse population. The authors used the 2001 California Health Interview Survey (CHIS 2001) to evaluate 1) rates(More)
