Understanding Regional Variation in the Cost of Breast Cancer Screening Among Privately Insured Women in the United States.

ABSTRACT:

Background

Breast cancer screening for women aged 40-49 years is prevalent and costly, with costs varying substantially across US regions. Newer approaches to mammography may improve cancer detection but also increase screening costs. We assessed factors associated with regional variation in screening costs.

Methods

We used Blue Cross Blue Shield Axis, a large US commercial claims database accessed through secure portal, to assess regional variation in screening utilization and costs. We included screening mammography±digital breast tomosynthesis (DBT), screening ultrasound, diagnostic mammography±DBT, diagnostic ultrasound, magnetic resonance imaging and biopsy, and evaluated their utilization and costs. We assessed regional variation in annual per-screened-beneficiary costs and examined potential savings from reducing regional variation.

Results

Of the 2,257,393 privately insured women, 41.2% received screening mammography in 2017 (range: 26.6%-54.2% across regions). Wide regional variation was found in the DBT proportion (0.7%-91.1%) and mean costs of DBT ($299; range: $113-714) and 2-dimensional (D) mammograms ($213; range: $107-471). In one-fourth of the regions, the mean DBT cost was lower than the mean 2D mammography cost in the full sample. Regional variation in the per-screened-beneficiary cost (mean: $353; range: $151-751) was mainly attributable to variation in the cost of DBT (accounting for 23.4% of regional variation) and 2D mammography (23.0%). Reducing regional variation by decreasing the highest values to the national mean was projected to save $79-335 million annually.

Conclusions

The mean mammogram cost for privately insured women ages 40-49 varies 7-fold across regions, driving substantial variation in breast cancer screening costs. Reducing this regional variation would substantially decrease the screening costs.

Project description:BackgroundInfants younger than 6 months are at increased risk of complications and mortality from pertussis infection. In October 2012, the Advisory Committee on Immunization Practices revised its recommendation to include a Tdap dose during each pregnancy, ideally between 27 and 36 weeks gestation.ObjectiveAssess trends in Tdap vaccination coverage among privately insured pregnant women from 2009 to 2016 including timing of Tdap vaccination (before, during, or after pregnancy), trimester of vaccination for women vaccinated during pregnancy, and missed vaccination opportunities for unvaccinated women. Identify factors associated with vaccination during the optimal period of 27-36 weeks gestation.Study designRetrospective analysis of privately insured women 15-49 years who delivered live births during 2009-2016 conducted using 2009-2016 MarketScan data. Tdap vaccination coverage and the timing of Tdap vaccine administration were assessed for women continuously enrolled from 6 months before pregnancy to 1 month after delivery. Multivariable logistic regression was performed to identify factors independently associated with receipt of Tdap vaccine at 27-36 weeks gestation.ResultsTdap vaccination coverage during pregnancy increased from 0.4% in 2009 to 6.2% in 2012 and to 53.2% in 2016. The proportion of vaccinated women receiving Tdap at 27-36 weeks gestation increased from <10% in 2009 to nearly 90% in 2016, with most vaccination occurring at 27-32 weeks gestation. Women of older age, residing in a metropolitan statistical area, residing outside the South, and having a capitated health insurance plan were more likely to receive Tdap at 27-36 weeks gestation than their counterparts. Among women not vaccinated during pregnancy, 77.7% had a pregnancy-related medical claim between 27 and 36 weeks gestation.ConclusionTdap vaccination coverage during pregnancy increased significantly from 2009 to 2016, with the greatest increase occurring after the revised Advisory Committee on Immunization Practices recommendation. Most women who did not receive Tdap vaccine had a missed vaccination opportunity during pregnancy, indicating potential for much higher vaccination coverage and consequent infant protection against pertussis.

Project description:OBJECTIVE:To analyze utilization of, and payments for, pelvic organ prolapse procedures after the 2011 U.S. Food and Drug Administration (FDA) communication regarding transvaginal mesh. METHODS:This is a retrospective cohort study examining private claims from three insurance providers for inpatient and outpatient prolapse procedures from 2010 to 2013 in the Health Care Cost Institute. Primary outcomes were the change in utilization of prolapse procedures, with and without mesh, before and after the July 2011 FDA communication. Secondary outcomes were the changes in payments and reimbursements for these procedures. Utilization rates and payments were compared using generalized linear models and interrupted time-series analysis. RESULTS:Utilization of prolapse procedures decreased from 12.3 to 9.7 per 10,000 woman-years (P=.027) with a decrease of 30.7% (3.9 in 2010 to 2.7 in 2013, P=.05) in number of mesh procedures and 16.6% (8.4 in 2010 to 7.0 in 2013, P=.011) for nonmesh procedures. Quarterly utilization of mesh procedures was increasing before the FDA communication and then significantly declined after its release (slope=0.024 vs -0.025, P=.002). Nonmesh procedures, however, were already slightly decreasing before July 2011 and continued to decline at a more rapid pace after that time, although not significantly (slope=-0.004 vs -0.022, P=.47). Inpatient utilization decreased 52.2% (P=.002), whereas outpatient utilization increased 18.5% (P=.132). Payments for individual inpatient procedures, with and without mesh, increased by 12.0% ($8,315 in 2010 to $9,315 in 2013, P=.001) and 15.6% ($7,826 in 2010 to $9,048 in 2013, P=.005), respectively, whereas those for outpatient procedures increased by 41% ($4,961 in 2010 to $6,981 in 2013, P=.006) and 30% ($3,955 in 2010 to $5,149 in 2013, P=.004), respectively. CONCLUSION:Use of prolapse surgery declined during the study period. After the 2011 FDA communication regarding transvaginal mesh, there was a significant decrease in the utilization of procedures with mesh but not for those without mesh. A shift toward outpatient surgeries was observed, and payments for both individual inpatient and outpatient cases increased.

Project description:Importance:To achieve the World Health Organization goal of viral hepatitis elimination by 2030, it is important to estimate current rates of chronic hepatitis B (CHB) diagnosis and treatment. Objective:To provide an accurate accounting of the number of patients with CHB aged 6 years or older who have not yet been diagnosed in the United States. Design, Setting, and Participants:This cross-sectional study used the commercial US Truven Health MarketScan Database (138 634 154 privately insured individuals in January 2007 to December 2014) to identify patients with CHB diagnosis and the National Health and Nutrition Examination Survey to estimate the actual number of privately insured persons with CHB. Based on sex and age distribution derived from the US Census Bureau, we calculated the total population with CHB and the proportion of those who remained undiagnosed among the 198 073 302 privately insured individuals. Next, we identified diagnosed CHB patients who received 1 or more prescription for CHB medications to calculate the treatment rate for those with severe disease states, such as cirrhosis and hepatocellular carcinoma, that would warrant treatment. Analyses were performed from October 2017 to January 2020. Main Outcomes and Measures:The rate and number of patients with CHB who remained undiagnosed and treatment rates for patients with CHB who have cirrhosis or hepatocellular carcinoma. Results:Among the 198 073 302 privately insured individuals (48.55% male; 15.52% aged 6-17 years; 84.48% aged ≥18 years), there were 511 029 (95% CI, 317 733-704 325) individuals with CHB, but only 95 075 of these had been diagnosed, yielding a diagnosis rate of only 18.60% (95% CI, 13.50%-29.92%), meaning that 81.40% (95% CI, 70.08%-86.50%) were undiagnosed. The treatment rates were 34.79% (95% CI, 33.31%-36.27%) for those with cirrhosis and 48.64% (95% CI, 45.59%-51.69%) for those with hepatocellular carcinoma. Conclusions and Relevance:In this study, only approximately 1 in 5 privately insured patients with CHB had been diagnosed. Only one-third of patients with CHB who had cirrhosis and one-half who had hepatocellular carcinoma received antiviral therapy. Further efforts are needed to improve the current situation of poor connection to care for patients with CHB, especially for those with advanced liver disease.
