Supplemental Breast Imaging Utilization After Breast Density Legislation in North Carolina.

ABSTRACT:

Purpose

Breast density notification laws are increasingly common but little is known of how they affect supplemental screening use. The aim of this study was to investigate supplemental screening before and after density notification in North Carolina, where notification has been required since 2014.

Methods

Breast screening data from Carolina Mammography Registry participants aged 40 to 79 years with no personal histories of breast cancer or breast implants were evaluated. Supplemental screening was defined as a nondiagnostic digital breast tomosynthesis (DBT), whole-breast ultrasound, or breast MRI performed within 3 months of negative or benign results on screening mammography (2-D or DBT). Supplemental screening before (2012-2013) and after (2014-2016) the notification law was compared using logistic regression.

Results

During the study period, 78,967 women underwent 145,279 index screening mammographic examinations. Supplemental screening use was similar before and after the notification law, regardless of breast density (dense breasts: adjusted odds ratio [aOR], 1.01; 95% confidence interval [CI], 0.58-1.75; nondense breasts: aOR, 0.63; 95% CI, 0.38-1.04). Although there was no change in supplemental screening, new use of any screening DBT from 2014 to 2016 was greater for women with dense breasts (versus nondense breasts; aOR, 1.15; 95% CI, 1.08-1.23).

Conclusions

Data suggest that supplemental screening use in North Carolina did not change after enactment of a breast density notification law, though the increase in new use of any screening DBT was greater for women with dense breasts. The short-term lack of change in supplemental screening should be considered as additional notification laws are developed.

Project description:BackgroundTwenty-eight states have passed breast density notification laws, which require physicians to inform women of a finding of dense breasts on mammography.ObjectiveTo evaluate changes in breast cancer stage at diagnosis after enactment of breast density notification legislation.DesignUsing a difference-in-differences analysis, we examined changes in stage at diagnosis among women with breast cancer in Connecticut, the first state to enact legislation, compared to changes among women in control states. We used data from the Surveillance, Epidemiology, and End Results Program (SEER) registry, 2005-2013.ParticipantsWomen ages 40-74 with breast cancer.InterventionBreast density notification legislation, enacted in Connecticut in October of 2009.Main measureBreast cancer stage at diagnosis.Key resultsOur study included 466,930 women, 25,592 of whom lived in Connecticut. Legislation was associated with a 1.38-percentage-point (95 % CI 0.12 to 2.63) increase in the proportion of women in Connecticut versus control states who had localized invasive cancer at the time of diagnosis, and a 1.12-percentage-point (95 % CI -2.21 to -0.08) decline in the proportion of women with ductal carcinoma in situ at diagnosis. Breast density notification legislation was not associated with a change in the proportion of women in Connecticut versus control states with regional-stage (-0.09 percentage points, 95 % CI -1.01 to 1.02) or metastatic disease (-0.24, 95 % CI -0.75 to 0.28). County-level analyses and analyses limited to women younger than 50 found no statistically significant associations.LimitationsSingle intervention state, limited follow-up, potential confounding from unobserved trends.ConclusionsBreast density notification legislation in Connecticut was associated with a small increase in the proportion of women diagnosed with localized invasive breast cancer in individual-level but not county-level analyses. Whether this finding reflects potentially beneficial early detection or potentially harmful overdiagnosis is not known. Legislation was not associated with changes in regional or metastatic disease.

Project description:Breast cancer brain metastasis (BCBM) confers a poor prognosis and is unusual in requiring multidisciplinary care in the metastatic setting. The University of North Carolina at Chapel Hill (UNC-CH) has created a BCBM clinic to provide medical and radiation oncology, neurosurgical, and supportive services to this complex patient population. We describe organization and design of the clinic as well as characteristics, treatments, and outcomes of the patients seen in its first 3 years.Clinical and demographic data were collected from patients in a prospectively maintained database. Descriptive statistics are reported as percentages and means. The Kaplan-Meier method was used to estimate time-to-event outcomes.Sixty-five patients were seen between January 2012 and January 2015. At the time of presentation to the BCBM clinic, most patients (74%) had multiple (?2) brain metastases and had received prior systemic (77%) and whole-brain radiation therapy and/or central nervous system stereotactic radiosurgery (65%) in the metastatic setting. Seventy-eight percent returned for a follow-up visit; 32% were enrolled in a clinical trial. Median time from diagnosis of brain metastasis to death was 2.11 years (95% confidence interval [CI] 1.31-2.47) for all patients, 1.15 years (95% CI 0.4-2.43) for triple-negative breast cancer, 1.31 years (95% CI 0.51-2.52) for hormone receptor-positive/HER2- breast cancer, and 3.03 years (95% CI lower limit 1.94, upper limit not estimable) for HER2+ breast cancer (p = .0037).Patients with BCBM have unique and complex needs that require input from several oncologic disciplines. The development of the UNC-CH multidisciplinary BCBM clinic is a model that can be adapted at other centers to provide coordinated care for patients with a challenging and complex disease.Patients with breast cancer brain metastases often require unique multidisciplinary care to meet the numerous and uncommon challenges associated with their conditions. Here, the development and characteristics of a clinic designed specifically to provide for the multidisciplinary needs of patients with breast cancer brain metastases are described. This clinic may serve as a model for other institutions interested in creating specialty clinics with similar objectives.

Project description:Purpose: The emergence of the COVID-19 pandemic led health care systems and providers worldwide to rapidly adopt telehealth solutions to minimize risk and comply with isolation mandates. This article explores telehealth utilization trends in North Carolina (NC) free and charitable clinics—an ambulatory health care delivery setting where traditional third-party reimbursement policies are not a primary consideration. Methods: We surveyed NC free and charitable clinic administrators regarding clinic decisions to adopt an externally sponsored telehealth system, what services are provided by telehealth, clinic implementation processes, which populations used telehealth, how telehealth was incorporated into current clinic workflows, and perceptions of telehealth outcomes. Findings: Telehealth was rapidly adopted among free and charitable clinics after the COVID-19 outbreak. Reasons for implementing telehealth included the ability to continue providing services during a public health emergency and to increase access to patients. However, clinics report that telehealth utilization has dropped significantly since the initial pandemic surge. Patient and provider preferences for in-person services are a common reason cited for this drop. Free and charitable clinics report a strong interest in continuing to deliver services through telehealth. The majority reported continuing to offer telehealth services, but primarily as a supplement to in-person visits rather than as a replacement. They perceive that implementing telehealth has increased access to care but are less certain about the impact on cost of care and patient satisfaction. However, clinic administrators believe improvements in interoperability with other data systems, workflows, scheduling, and care delivery approaches are needed to achieve telehealth's fullest utilization. Conclusion: Telehealth can play a significant role in expanding access to services in the free and charitable clinic setting. However, continued refinements in the technology to facilitate integration with other systems and workflow processes are needed to reach its full potential.
