Project description:BackgroundMenopausal hormone therapy (MHT) can elevate venous thromboembolism (VTE) risk, but less is known about formulations and routes of exposures.ObjectiveTo estimate hormone-associated VTE risk by route and formulation in exposed and unexposed women aged 50 to 64 years in the US.MethodsIn a nested case-control study of US commercially insured women aged 50 to 64 years (2007-2019), cases were defined as incident VTE diagnoses and matched to 10 controls by date of VTE and age, excluding prior VTE, inferior vena cava filter placement, or anticoagulants. Filled prescriptions in the prior year defined hormone exposures. International Classification of Diseases and Current Procedural Terminology codes identified risk factors and comorbidities.ResultsOdds ratios (ORs) were estimated with conditional logistic regression controlling for differences between cases (n = 20,359) and controls (n = 203,590) in comorbidities and VTE risk factors. For exposures within 60 days, oral MHT risk was almost twice as high as transdermal MHT (OR = 1.92; 95% CI, 1.43-2.60); transdermal MHT did not elevate risk compared with no exposure (unopposed OR = 0.70; 95% CI, 0.59-0.83; combined OR = 0.73; 95% CI, 0.56-0.96). Risk was highest for MHT combinations with ethinyl estradiol, followed by conjugated equine estrogen (CEE) (ethinyl estradiol-CEE: OR = 1.55; 95% CI, 1.07-2.25), and lowest for estradiol (CEE-estradiol: OR = 1.33; 95% CI, 1.02-1.72). Combined hormonal contraceptives elevated risk 5 times higher than no exposure (OR = 5.22; 95% CI, 4.67-5.84) and 3 times higher than oral MHT (OR = 3.65; 95% CI, 3.09-4.31).ConclusionThe risk of VTE is much lower with MHT than combined hormone contraceptives and varies by hormone formulation and route of exposure. Transdermal MHT did not elevate risk. Oral MHT combinations with estradiol were lower risk than other forms of estrogen. Oral combined hormone contraceptives had much higher risk than oral combined hormonal MHT.

Project description:PurposeWe examined 12-year trends in BRCA testing rates and costs in the context of clinical guidelines, national policies, and other factors.MethodsWe estimated trends in BRCA testing rates and costs from 2003 to 2014 for women aged 18-64 years using private claims data and publicly reported revenues from the primary BRCA testing provider.ResultsThe percentage of women with zero out-of-pocket payments for BRCA testing increased during 2013-2014, after 7 years of general decline, coinciding with a clarification of Affordable Care Act coverage of BRCA genetic testing. Beginning in 2007, family history accounted for an increasing proportion of women with BRCA tests compared with personal history, coinciding with BRCA testing guidelines for primary care settings and direct-to-consumer advertising campaigns. During 2013-2014, BRCA testing rates based on claims grew at a faster rate than revenues, following 3 years of similar growth, consistent with increased marketplace competition. In 2013, BRCA testing rates based on claims increased 57%, compared with 11% average annual increases over the preceding 3 years, coinciding with celebrity publicity.ConclusionThe observed trends in BRCA testing rates and costs are consistent with possible effects of several factors, including the Affordable Care Act, clinical guidelines and celebrity publicity.

Project description:BackgroundDigital breast tomosynthesis (DBT) may have a higher cancer detection rate and lower recall compared with 2-dimensional (2 D) mammography for breast cancer screening. The goal of this study was to evaluate screening outcomes with DBT in a real-world cohort and to characterize the population health impact of DBT as it is widely adopted.MethodsThis observational study evaluated breast cancer screening outcomes among women screened with 2 D mammography vs DBT. We used deidentified administrative data from a large private health insurer and included women aged 40-64 years screened between January 2015 and December 2017. Outcomes included recall, biopsy, and incident cancers detected. We used 2 complementary techniques: a patient-level analysis using multivariable logistic regression and an area-level analysis evaluating the relationship between population-level adoption of DBT use and outcomes. All statistical tests were 2-sided.ResultsOur sample included 7 602 869 mammograms in 4 580 698 women, 27.5% of whom received DBT. DBT was associated with modestly lower recall compared with 2 D mammography (113.6 recalls per 1000 screens, 99% confidence interval [CI] = 113.0 to 114.2 vs 115.4, 99% CI = 115.0 to 115.8, P < .001), although younger women aged 40-44 years had a larger reduction in recall (153 recalls per 1000 screens, 99% CI = 151 to 155 vs 164 recalls per 1000 screens, 99% CI = 163 to 166, P < .001). DBT was associated with higher biopsy rates than 2 D mammography (19.6 biopsies per 1000 screens, 99% CI = 19.3 to 19.8 vs 15.2, 99% CI = 15.1 to 15.4, P < .001) and a higher cancer detection rate (4.9 incident cancers per 1000 screens, 99% CI = 4.7 to 5.0 vs 3.8, 99% CI = 3.7 to 3.9, P < .001). Point estimates from the area-level analysis generally supported these findings.ConclusionsIn a large population of privately insured women, DBT was associated with a slightly lower recall rate than 2 D mammography and a higher cancer detection rate. Whether this increased cancer detection improves clinical outcomes remains unknown.

Project description:ObjectiveTo assess national trends in out-of-pocket (OOP) costs among adults aged 18-64 years with diabetes in the U.S.Research design and methodsUsing data from the 2001-2017 Medical Expenditure Panel Survey, we estimated total per person annual OOP costs (insurance premiums, prescription drug costs, inpatient and outpatient deductibles, copays, and other payments not covered by insurance) and high OOP cost rate, defined as the percentage of people with OOP spending >10% of their family's pretax income. We examined trends overall, by subgroup (insurance type, income level, insulin use, size of patient's employer, and whether the patient was enrolled in a high deductible health plan), and by type of service. Changes in trends were identified using joinpoint analysis; costs were adjusted to 2017 U.S. dollars.ResultsFrom 2001 to 2017, OOP costs decreased 4.3%, from $4,328 to $4,139, and the high OOP cost rate fell 32%, from 28 to 19% (P < 0.001). Changes in the high OOP cost rate varied by subgroup, declining among those with public or no insurance and those with an income <200% of the federal poverty level (P < 0.001) but remaining stable among those with private insurance and higher income. Drug prescription OOP costs decreased among all subgroups (P < 0.001). Decreases in total (-$58 vs. -$37, P < 0.001) and prescription (-$79 vs. -$68, P < 0.001) OOP costs were higher among insulin users than noninsulin users.ConclusionsOOP costs among U.S. nonelderly adults with diabetes declined, especially among those least able to afford them. Future studies may explore factors contributing to the decline in OOP costs and the impact on the quality of diabetes care and complication rates.

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:PurposeImmediate-release forms of generic mixed amphetamine salts (MAS) have been the subject of passive surveillance reports signaling lack of effectiveness. We examined switching patterns that might suggest whether long-term users of specific MAS are more likely to switch away or switch back after use of the MAS of interest in the FDA's Sentinel Distributed Database.MethodsWe required at least 60-day continuous supply of selected MAS grouped by Abbreviated New Drug Application (ANDA) to describe patterns of switching away from and to generics approved under the ANDAs of interest among individuals ages 15-64 years with attention deficit hyperactivity disorder or narcolepsy during 2013-2019.ResultsWe observed the greatest number of treatment episodes for ANDA 040422 (n = 525 771), followed by ANDA 202424 (n = 181 693), ANDA 040439 (n = 62 363), ANDA 040440 (n = 21 143), and ANDA 040480 (n = 8792). Of those with switches away from their original ANDA, episodes initiated on generic products under ANDA 040422 (48.6%) and ANDA 202424 (43.0%) were most likely to switch back, while those initiated on generic product under ANDA 040480 were least likely (24.1%). Of those episodes with switches to a generic under an ANDA of interest, about one-third (range 27.1% to 37.0%) switched back to the same product. These switches back had a median time to switch of about 30 days.ConclusionsThese descriptive analyses, although subject to limitations, did not suggest increased switching away or switching back after use of the generics of interest. Continued post-marketing surveillance is warranted.

Project description:ObjectiveTo estimate trends of annual antipsychotic medication use by privately insured young children (aged 2-7 years) in the United States, and to describe the clinical and treatment characteristics of these children.MethodThe study population included young children from a nationwide commercial claims database (2007-2017). We estimated annual antipsychotic use by age and sex, defined as the number of children dispensed an antipsychotic per year divided by the number enrolled. We described clinical diagnoses and mental health service use in those with prescription antipsychotic use in 2009 and 2017.ResultsAnnual antipsychotic use in young children was 0.27% in 2007, peaked at 0.29% in 2009, and statistically significantly declined to 0.17% by 2017 (linear trend: -0.017% per year, 95% CI: -0.018 to -0.016). Antipsychotic use was higher in boys than in girls. A greater proportion of antipsychotic users received a mental disorder diagnosis in 2017 (89%) than in 2009 (86%, p < .01). The most common clinical diagnoses in antipsychotic users, under a hierarchical classification, were pervasive developmental disorder (2009 = 27%, 2017 = 38%, p < .01), conduct or disruptive behavior disorder (2009 = 15%, 2017 = 21%, p < .01), and attention-deficit/hyperactivity disorder (2009 = 24%, 2017 = 18%, p < .01). Among 2017 antipsychotic users, 32% had 4+ psychotherapy claims, 43% had a psychiatrist visit, and the majority used another psychotropic medication, most commonly a stimulant (boys = 57%, girls = 50%).ConclusionIn privately insured young children, antipsychotic use declined from 2009 to 2017, with shifts toward indications with some supporting evidence. Nevertheless, a majority of use remains off label and for conditions lacking effectiveness and safety data. Improving antipsychotic prescribing in young children remains a challenge.
