Number of children and risk of dementia
BACKGROUND: Findings on the link between the number of children and dementia risk are inconsistent, mostly studied in females, suggesting pregnancy-related changes may be a key factor in this association. METHODS: The Adult Changes in Thought Study is a cohort of adults aged ≥65 years from Kaiser Permanente Washington. The primary exposure was the number of children (0, 1, 2, 3 or ≥4), and the outcome was an incident dementia diagnosis. Cox propo…
Does Living near Trees and Other Vegetation Affect the Contemporaneous Odds of Asthma Exacerbation among Pediatric Asthma Patients
Stability of food insecurity status in paediatric primary care
Objective: The American Academy of Pediatrics recommends screening for food insecurity (FI) at all well-child visits due to well-documented negative effects of experiencing FI in childhood. Before age 3, children have twelve recommended primary care visits at which screening could occur. Little is known regarding the stability of FI status at this frequency of screening. Design: Data derived from electronic health records were used to retrospecti…
An Electronic Health Record–based Algorithm to Ascertain the Date of Second Breast Cancer Events
OBJECTIVES: Studies of cancer recurrences and second primary tumors require information on outcome dates. Little is known about how well electronic health record-based algorithms can identify dates or how errors in dates can bias analyses. RESEARCH DESIGN: We assessed rule-based and model-fitting approaches to assign event dates using a previously published electronic health record-based algorithm for second breast cancer events (SBCE). We conduc…
Breast MRI in the Diagnostic and Preoperative Workup Among Medicare Beneficiaries With Breast Cancer
PURPOSE: We compared the frequency and sequence of breast imaging and biopsy use for the diagnostic and preoperative workup of breast cancer according to breast magnetic resonance imaging (MRI) use among older women. MATERIALS AND METHODS: Using SEER-Medicare data from 2004 to 2010, we identified women with and without breast MRI as part of their diagnostic and preoperative breast cancer workup and measured the number and sequence of breast imagi…
Validation of a Medicare Claims-based Algorithm for Identifying Breast Cancers Detected at Screening Mammography
BACKGROUND: The breast cancer detection rate is a benchmark measure of screening mammography quality, but its computation requires linkage of mammography interpretive performance information with cancer incidence data. A Medicare claims-based measure of detected breast cancers could simplify measurement of this benchmark and facilitate mammography quality assessment and research. OBJECTIVES: To validate a claims-based algorithm that can identify …
Characterization of Dementia and Alzheimer’s Disease in an Older Population
Objectives. We estimated dementia incidence rates, life expectancies with and without dementia, and percentage of total life expectancy without dementia. Methods. We studied 3605 members of Group Health (Seattle, WA) aged 65 years or older who did not have dementia at enrollment to the Adult Changes in Thought study between 1994 and 2008. We estimated incidence rates of Alzheimer’s disease and dementia, as well as life expectancies with and witho…
Distinguishing Screening From Diagnostic Mammograms Using Medicare Claims Data
BACKGROUND: Medicare claims data may be a fruitful data source for research or quality measurement in mammography. However, it is uncertain whether claims data can accurately distinguish screening from diagnostic mammograms, particularly when claims are not linked with cancer registry data. OBJECTIVES: To validate claims-based algorithms that can identify screening mammograms with high positive predictive value (PPV) in claims data with and witho…
Timeliness of Abnormal Screening and Diagnostic Mammography Follow-up at Facilities Serving Vulnerable Women
BACKGROUND: Whether timeliness of follow-up after abnormal mammography differs at facilities serving vulnerable populations, such as women with limited education or income, in rural areas, and racial/ethnic minorities is unknown. METHODS: We examined receipt of diagnostic evaluation after abnormal mammography using 1998-2006 Breast Cancer Surveillance Consortium-linked Medicare claims. We compared whether time to recommended breast imaging or bio…
Effects of Digital Mammography Uptake on Downstream Breast-related Care Among Older Women
BACKGROUND: Digital mammography is the dominant modality for breast cancer screening in the United States. No previous studies have investigated as to how introducing digital mammography affects downstream breast-related care. OBJECTIVE: Compare breast-related health care use after a screening mammogram before and after introduction of digital mammography. RESEARCH DESIGN AND SUBJECTS: Longitudinal study of screening mammograms from 14 radiology …
Assessing Health Care Use and Cost Consequences of a New Screening Modality
BACKGROUND: Full-field digital mammography (FFDM) has largely replaced screen-film mammography (SFM) for breast cancer screening, but how this affects downstream breast-related use and costs is unknown. OBJECTIVES: To compare breast-related health care use and costs among Medicare beneficiaries undergoing SFM versus FFDM from 1999 to 2005. DESIGN: Retrospective cohort study. SUBJECTS: Medicare-enrolled women aged 66 and older with mammograms in B…
Cold-related cardiac mortality in King County, Washington, USA 1980–2001
Cold temperatures may be an important triggering factor in bringing on the onset of life-threatening cardiac events, even in regions with relatively mild winters. Public health efforts stressing cold exposure while out of doors may play a prominent role in encouraging a reduction in cold stress, especially among seniors and those already at higher risk of cardiac death
