Mammography Use Among Women Ages 40-49 After the 2009 U.S. Preventive Services Task Force Recommendation
ABSTRACT BACKGROUND: In 2009, the U.S. Preventive Service Task Force changed its recommendation regarding screening mammography in average-risk women aged 40-49 years. OBJECTIVE: To evaluate the effects of the 2009 recommendation on reported mammogram use in a population-based survey. DESIGN: Secondary data analysis of data collected in the 2006, 2008, and 2010 Behavioral Risk Factor Surveillance System surveys. PARTICIPANTS: Women ages 40-74 years in the 50 states and Washington, DC who were not pregnant at time of survey and reported data on mammogram use during the 2006, 2008, or 2010 survey. MAIN MEASURES: Mammogram use was compared between women ages 40-49 and women ages 50-74 before and after the recommendation. We performed a difference-in-difference estimation adjusted for access to care, education, race, and health status, and stratified analyses by whether women reported having a routine checkup in the prior year. KEY RESULTS: Reported prevalence of mammogram use in the past year among women ages 40-49 and 50-74 was 53.2 % and 65.2 %, respectively in 2008, and 51.7 % and 62.4 % in 2010. In 2010, mammography use did not significantly decline from 2006-2008 in women ages 40-49 relative to women ages 50-74. CONCLUSION: There was no reduction in mammography use among younger women in 2010 compared to older women and previous years. Patients and providers may have been hesitant to comply with the 2009 recommendation.

ABSTRACT: The 2009 US Preventive Services Task Force breast cancer screening update recommended against routine screening mammography for women aged 40-49; confusion and release of conflicting guidelines followed. We examined the impact of the USPSTF update on population-level screening mammography rates in women ages 40-49. We conducted a retrospective, interrupted time-series analysis using a nationally representative, privately-insured population from 1/1/2006-12/31/2011. Women ages 40-64 enrolled for ≥1 month were included. The primary outcome was receipt of screening mammography, identified using administrative claims-based algorithms. Time-series regression models were estimated to determine the effect of the guideline change on screening mammography rates. 5.5 million women ages 40-64 were included. A 1.8 per 1,000 women (p = 0.003) decrease in monthly screening mammography rates for 40-49 year-old women was observed two months following the guideline change; no initial effect was seen for 50-64 year-old women. However, two years following the guideline change, a slight increase in screening mammography rates above expected was observed in both age groups. We detected a modest initial drop in screening mammography rates in women ages 40-49 immediately after the 2009 USPSTF guideline followed by an increase in screening rates. Unfavorable public reactions and release of conflicting statements may have tempered the initial impact. Renewal of the screening debate may have brought mammography to the forefront of women's minds, contributing to the observed increase in mammography rates two years after the guideline change. This pattern is unlikely to reflect informed choice and underscores the need for improved translation of evidence-based care and guidelines into practice.PLoS ONE 03/2014; 9(3):e91399.

ABSTRACT: Background: This study investigates factors that are associated with nonadherence to mammography screening guidelines in Utah, a state where mammography screening rates have remained consistently lower than national averages. Methods: We examined data on reported mammography use among women aged 40-74 years from the 2008 and 2010 Utah Behavioral Risk Factor Surveillance System (n=5,197, weighted n=417,064). Logistic regression models were used to estimate the effects of individual-level and geographic (travel time to nearest mammography facility, geographic accessibility, and rural/urban residence) factors on the odds of a woman not reporting receiving a mammogram in the last 2 years. Results: In 2008 and 2010, a disproportionate number of women aged 40-49 (43.1%, 95% confidence interval [CI] 39.9%-46.3%) reported not receiving a mammogram within the last 2 years compared to women 50-74 (26.8%, 95% CI 24.9%-28.7%). None of the geographic factors were significant predictors of screening adherence. Based on covariate adjusted models, statistically significant (p<0.05) factors associated with increased odds of not receiving mammogram within the last 2 years included not having a regular physician, no health insurance, being aged 40-49, income less than $25,000, and the presence of three or more children in the home. Conclusion: Mammography screening efforts in Utah should focus on improving access to insurance or a regular source of health care. Future research should also consider how best to address extreme time demands and competing priorities that present potential barriers for women with large families, resulting in lower screening levels among these women.Journal of Women's Health 05/2014; 23(8).

ABSTRACT: BACKGROUND In October 2008, the Centers for Medicare & Medicaid Services (CMS) stopped reimbursing hospitals for the marginal cost of treating certain preventable hospital-acquired conditions. OBJECTIVE This study evaluates whether CMS’s refusal to pay for hospital-acquired pulmonary embolism (PE) or deep vein thrombosis (DVT) resulted in a lower incidence of these conditions. DESIGN We employ difference-in-differences modeling using 2007–2009 data from the Nationwide Inpatient Sample, an all-payer database of inpatient discharges in the U.S. Discharges between 1 January 2007 and 30 September 2008 were considered “before payment reform;” discharges between 1 October 2008 and 31 December 2009 were considered “after payment reform.” Hierarchical regression models were fit to account for clustering of observations within hospitals. PARTICIPANTS The “before payment reform” and “after payment reform” incidences of PE or DVT among 65–69-year-old Medicare recipients were compared with three different control groups of: a) 60–64-year-old non-Medicare patients; b) 65–69-year-old non-Medicare patients; and c) 65–69-year-old privately insured patients. Hospital reimbursements for the control groups were not affected by payment reform. INTERVENTION CMS payment reform for hospital-based reimbursement of patients with hip and knee replacement surgeries. MAIN MEASURES The outcome was the incidence proportion of hip and knee replacement surgery admissions that developed pulmonary embolism or deep vein thrombosis. KEY RESULTS At baseline, pulmonary embolism or deep vein thrombosis were present in 0.81 % of all hip or knee replacement surgeries for Medicare patients aged 65–69 years old. CMS payment reform resulted in a 35 % lower incidence of hospital-acquired pulmonary embolism or deep vein thrombosis in these patients (p = 0.015). Results were robust to sensitivity analyses. CONCLUSION CMS’s refusal to pay for hospital-acquired conditions resulted in a lower incidence of hospital-acquired pulmonary embolism or deep vein thrombosis after hip or knee replacement surgery. Payment reform had the desired direction of effect.Journal of General Internal Medicine 12/2014; 30(5). DOI:10.1007/s11606-014-3087-3 · 3.45 Impact Factor
