IMPORTANCE: Overtreatment of early-stage breast cancer results in increased morbidity and cost without improving survival. Major surgical organizations participating in the Choosing Wisely campaign ...identified 4 breast cancer operations as low value: (1) axillary lymph node dissection for limited nodal disease in patients receiving lumpectomy and radiation, (2) re-excision for close but negative lumpectomy margins for invasive cancer, (3) contralateral prophylactic mastectomy in patients at average risk with unilateral cancer, and (4) sentinel lymph node biopsy in women 70 years or older with hormone receptor–positive cancer. OBJECTIVE: To evaluate the extent to which these procedures have been deimplemented, determine the implications of decreased use, and recognize possible barriers and facilitators to deimplementation. EVIDENCE REVIEW: A systematic review of published literature on use trends in breast surgery was performed in accordance with PRISMA guidelines. The Ovid, Embase, Cumulative Index to Nursing and Allied Health Literature, and Cochrane databases were searched for original research with relevance to the Choosing Wisely recommendations of interest. Eligible studies were examined for data about use, and any patient-level, clinician-level, or system-level factors associated with use. FINDINGS: Concordant with recommendations, national rates of axillary lymph node dissection for patients with limited nodal disease have decreased by approximately 50% (from 44% in 2011 to 30% to 34% in 2012 and 25% to 28% in 2013), and national rates of lumpectomy margin re-excision have decreased by nearly 40% (from 16% to 34% before to 14% to 18% after publication of a consensus statement). Conversely, national rates of contralateral prophylactic mastectomy continue to rise each year, accounting for up to 30% of all mastectomies for breast cancer (range in all mastectomy cases: 2010-2012, 28%-30%; 1998, <2%), and rates of sentinel lymph node biopsy in women 70 years or older with low-risk breast cancer are persistently greater than 80% (range, 80%-88%). Factors associated with high rates of contralateral prophylactic mastectomy use are younger age, white race, increased socioeconomic status, and the availability of breast reconstruction; limited data exist on factors associated with high rates of sentinel lymph node biopsy in women 70 years or older. Successful deimplementation of axillary lymph node dissection and lumpectomy margin re-excision were associated with decreased costs and improved patient-centered outcomes. CONCLUSIONS AND RELEVANCE: This review demonstrates variable deimplementation of 4 low-value surgical procedures in patients with breast cancer. Addressing specific patient-level, clinician-level, and system-level barriers to deimplementation is necessary to encourage shared decision-making and reduce overtreatment.
Human brown adipose tissue (BAT) can be activated to increase glucose uptake and energy expenditure, making it a potential target for treating obesity and metabolic disease. Data on the functional ...and anatomic characteristics of BAT are limited, however. In 20 healthy young men 12 lean, mean body mass index (BMI) 23.2 ± 1.9 kg/m²; 8 obese, BMI 34.8 ± 3.3 kg/m² after 5 h of tolerable cold exposure, we measured BAT volume and activity by 18F-labeled fluorodeoxyglucose positron emission tomography/computerized tomography (PET/CT). Obese men had less activated BAT than lean men (mean, 130 vs. 334 mL) but more fat in BAT-containing depots (mean, 1,646 vs. 855 mL) with a wide range (0.1–71%) in the ratio of activated BAT to inactive fat between individuals. Six anatomic regions had activated BAT—cervical, supraclavicular, axillary, mediastinal, paraspinal, and abdominal—with 67 ± 20% of all activated BAT concentrated in a continuous fascial layer comprising the first three depots in the upper torso. These nonsubcutaneous fat depots amounted to 1.5% of total body mass (4.3% of total fat mass), and up to 90% of each depot could be activated BAT. The amount and activity of BAT was significantly influenced by region of interest selection methods, PET threshold criteria, and PET resolutions. The present study suggests that active BAT can be found in specific adipose depots in adult humans, but less than one-half of the fat in these depots is stimulated by acute cold exposure, demonstrating a previously underappreciated thermogenic potential.
BACKGROUNDMirabegron is a β3-adrenergic receptor (β3-AR) agonist approved only for the treatment of overactive bladder. Encouraging preclinical results suggest that β3-AR agonists could also improve ...obesity-related metabolic disease by increasing brown adipose tissue (BAT) thermogenesis, white adipose tissue (WAT) lipolysis, and insulin sensitivity.METHODSWe treated 14 healthy women of diverse ethnicities (27.5 ± 1.1 years of age, BMI of 25.4 ± 1.2 kg/m2) with 100 mg mirabegron (Myrbetriq extended-release tablet, Astellas Pharma) for 4 weeks in an open-label study. The primary endpoint was the change in BAT metabolic activity as measured by 18F-2-fluoro-d-2-deoxy-d-glucose (18F-FDG) PET/CT. Secondary endpoints included resting energy expenditure (REE), plasma metabolites, and glucose and insulin metabolism as assessed by a frequently sampled intravenous glucose tolerance test.RESULTSChronic mirabegron therapy increased BAT metabolic activity. Whole-body REE was higher, without changes in body weight or composition. Additionally, there were elevations in plasma levels of the beneficial lipoprotein biomarkers HDL and ApoA1, as well as total bile acids. Adiponectin, a WAT-derived hormone that has antidiabetic and antiinflammatory capabilities, increased with acute treatment and was 35% higher upon completion of the study. Finally, an intravenous glucose tolerance test revealed higher insulin sensitivity, glucose effectiveness, and insulin secretion.CONCLUSIONThese findings indicate that human BAT metabolic activity can be increased after chronic pharmacological stimulation with mirabegron and support the investigation of β3-AR agonists as a treatment for metabolic disease.TRIAL REGISTRATIONClinicaltrials.gov NCT03049462.FUNDINGThis work was supported by grants from the Intramural Research Program of the NIDDK, NIH (DK075112, DK075116, DK071013, and DK071014).
IMPORTANCE: Through the Choosing Wisely campaign, surgical specialties identified 4 low-value breast cancer operations. Preliminary data suggest varying rates of deimplementation and have identified ...patient-level and clinician-level determinants of continued overuse. However, little information exists about facility-level variation or determinants of differential deimplementation. OBJECTIVE: To identify variation and determinants of persistent use of low-value breast cancer surgical care. DESIGN, SETTING, AND PARTICIPANTS: Retrospective cohort study in which reliability-adjusted facility rates of each procedure were calculated using random-intercept hierarchical logistic regression before and after evidence demonstrated that each procedure was unnecessary. The National Cancer Database is a prospective cancer registry of patients encompassing approximately 70% of all new cancer diagnoses from more than 1500 facilities in the United States. Data were analyzed from November 2019 to August 2020. The registry included women 18 years and older diagnosed as having breast cancer between 2004 and 2016 and meeting inclusion criteria for each Choosing Wisely recommendation. MAIN OUTCOMES AND MEASURES: Rate of each low-value breast cancer procedure based on facility type and breast cancer volume categories before and after the release of data supporting each procedure’s omission. RESULTS: The total cohort included 920 256 women with a median age of 63 years. Overall, 86% self-identified as White, 10% as Black, 3% as Asian, and 4.5% as Hispanic. Most women in this cohort were insured (51% private and 47% public), were living in a metropolitan or urban area (88% and 11%, respectively), and originated from the top half of income-earning households (65.5%). While there was significant deimplementation of axillary lymph node dissection and lumpectomy reoperation in response to guidelines supporting omission of these procedures, rates of contralateral prophylactic mastectomy and sentinel lymph node biopsy in older women increased during the study period. Academic research programs and high-volume facilities overall demonstrated the greatest reduction in use of these low-value procedures. There was significant interfacility variation for each low-value procedure. Facility-level axillary lymph node dissection rates ranged from 7% to 47%, lumpectomy reoperation rates ranged from 3% to 62%, contralateral prophylactic mastectomy rates ranged from 9% to 67%, and sentinel lymph node biopsy rates ranged from 25% to 97%. Pearson correlation coefficient for each combination of 2 of the 4 procedures was less than 0.11, suggesting that hospitals were not consistent in their deimplementation performance across all 4 procedures. Many were high outliers in one procedure but low outliers in another. CONCLUSIONS AND RELEVANCE: Interfacility variation demonstrates a performance gap and an opportunity for formal deimplementation efforts targeting each procedure. Several facility-level characteristics were associated with differential deimplementation and performance.
Background
Recognizing the need to raise awareness of core diversity, equity, and inclusion (DEI) issues in the healthcare system, our previously developed Cultural Complications Curriculum aims to ...support institutions in reducing cultural error. As we continue program deployment, we discuss the opportunity to apply the Cultural Complications Curriculum to multidisciplinary audiences, such as in cancer programs.
Methods
We discuss applicability of the Cultural Complications Curriculum to cancer programs and practices, including how to tailor case discussions to oncology audiences. By emphasizing the unique characteristics of the multidisciplinary care environment and anticipating potential barriers to curriculum implementation, we demonstrate how the Cultural Complications Curriculum may support culture improvement across broad audiences.
Results
The successful application of the Cultural Complication Curriculum to multidisciplinary care programs will depend on appreciating differences in background knowledge, tailoring discussions to audience needs, and adapting material by incorporating new data and addressing emerging DEI issues. Multidisciplinary environments may require innovative approaches to education including virtual platforms, increased collaboration across centers and systems, and support from professional societies. In integrated care environments, like oncology, effective DEI discussions call for the engagement of a variety of medical specialties and departments.
Conclusions
To meet the needs of an increasingly diverse patient population and workforce, our approach to DEI education must embrace the interdependent nature of care delivery. In oncology and other multidisciplinary care environments, application of the Cultural Complications Curriculum may be the first step to combating cultural error by engaging a broader demographic within our healthcare system.
For average-risk women with unilateral breast cancer, contralateral prophylactic mastectomy (CPM) offers no survival benefit and contributes to increased costs and patient harm. Despite ...recommendations from professional societies against CPM, utilization of this service is increasing, partly due to patients’ desire for breast symmetry when undergoing mastectomy. Most women with small tumors are candidates for breast-conserving surgery (BCS) and could avoid CPM. We describe CPM utilization in women with small, unilateral tumors, and identify determinants of possible overuse.
Using the National Cancer Database, we identified women with unilateral, T1 breast cancer. We evaluated utilization of BCS, unilateral mastectomy, and CPM and assessed patient, tumor, and facility factors associated with CPM.
Of 765,487 women with small, unilateral breast cancer, 69% underwent BCS and 31% chose mastectomy. Of 176,673 women ≥70 y, 75% underwent BCS and 25% chose mastectomy. CPM rates in both cohorts have increased since 2006. Decreased adjuvant radiotherapy in older women was associated with increased BCS rates. Patient factors (younger age, white race, private insurance, and breast reconstruction), tumor factors (lobular histology, higher grade, and human epidermal growth factor receptor 2 positive/estrogen receptor negative status), and facility factors (type and geographic location) were associated with increased CPM rates compared with unilateral mastectomy in multivariable models.
Most women with small unilateral breast cancer are candidates for BCS, yet one-third elects to undergo a mastectomy, of which a rising percentage opts for CPM. Tailoring deimplementation strategies to factors influencing treatment may help reduce CPM utilization and associated financial toxicity, pain, and disability.
Unnecessary health care not only drive up costs, but also contribute to avoidable patient harms, underscoring an ethical obligation to eliminate practices which are harmful, lack evidence, and ...prevent spending on more beneficial services. To date, de-implementation ethics discussions have been limited and focused on clinical ethics principles. An analysis of de-implementation ethics in the broader context of the health care system is lacking.
To better understand the ethical considerations of de-implementation, recognizing it as a health care systems issue, we applied Krubiner and Hyder's bioethical framework for health systems activity. We examine ethics principles relevant to de-implementation, which either call for or facilitate the reduction of low value surgery.
From 11 health systems principles proposed by Krubiner and Hyder, we identified the 5 principles most pertinent to the topic of de-implementation: evidence and effectiveness, transparency and public engagement, efficiency, responsiveness, and collaboration. An analysis of de-implementation through the lens of these principles not only supports de-implementation but proves an obligation at the health system level to eliminate low value care. Recognizing the challenge of defining “value,” the proposed framework may increase the legitimacy and objectivity of de-implementation.
While there is no single ideal ethical framework from which to approach de-implementation, a health systems framework allows for consideration of the systems-level factors impacting de-implementation. Framing de-implementation as a health systems issue with systems-wide ethical implications empowers providers to think about new ways to approach potential roadblocks to reducing low-value care.
Background
For women older than 70 years with early-stage breast cancer, the routine use of sentinel lymph node biopsy (SLNB) and adjuvant radiotherapy offers no overall survival benefit and may be ...perceived as undesirable by many women. National guidelines allow possible omission of these practices for older women. This study aimed to assess the availability of web-based educational materials targeting older women and their age-specific treatment recommendations.
Methods
The study systematically assessed the websites of the top 25 “Best Hospitals for Cancer” ranked by the
U.S. News & World Report,
as well as the websites of four prominent national cancer organizations.
Results
Websites for the leading cancer hospitals and national cancer organizations contain extremely limited information directed toward older patients with breast cancer. Both SLNB and adjuvant radiotherapy are described as treatments “typically,” “most often,” or “usually” used in combination with breast-conserving surgery without circumstances noted for possible omission. Specifically, no hospital website and only one national organization in this study included information on the recommendation to avoid routine SLNB. Only two hospitals and two national organizations included information suggesting possible omission of adjuvant radiotherapy for patients older than 70 years.
Conclusion
The absence of online material for older patients with breast cancer represents a gap potentially contributing to overtreatment by framing SLNB and adjuvant radiotherapy as necessary. Informational resources available to women aged 70 years or older may aid in informed physician–patient communication and decision-making, which may reduce SLNB and adjuvant radiotherapy for patients who might opt out of these procedures if fully informed about them.
Secrecy about a child’s difference of sex development (DSD) can lead to internalized shame and stigma. We explored how teenagers and adults with DSD, parents, healthcare providers, and allied ...professionals value and perceive patient education.
Stakeholders (n = 110) completed qualitative semi-structured interviews. Relevant themes for educational content were queried and organized.
Education was consistently identified as essential to successful outcomes. There was less consistency in how to educate patients. Disagreement existed regarding who should champion the education process. Participants believed medically relevant information should be shared gradually with attention to developmental capacity. Details were lacking regarding how much or what information to share. Participants noted that vetted resources were helpful. Benefits of sharing condition-specific information with patients included supporting their psychosocial development. Barriers included parental resistance to sharing information due to shame/stigma, and cultural and/or family dynamics.
Stakeholders’ different perspectives regarding patient DSD education warrant future research to focus on the design, evaluation, and implementation of education-focused interventions.
Healthcare providers are responsible for supporting the education of children and teenagers with DSD about their condition. When considering barriers, adopting a cultural or family systems framework can reduce parental resistance and promote open dialogue.
•Who: Providers and parents play a key role in supporting patient DSD education.•When: Educate gradually, considering patient questions and provider input.•What: Strike a balance between providing too much versus just enough information.•How: Use simple, positive language, educational materials, and repeat information.•Why: Educating children about their DSD is a key element of patient-centered care.
