Variations in Persistent Use of Low-Value Breast Cancer Surgery

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.

Patient Preferences in Cases of Inter-system Medical Error Discovery (IMED)

OBJECTIVE

This study analyzes patients' preferences around disclosure in cases of IMED.

BACKGROUND

Patients prefer that physicians disclose their self-discovered medical errors, and disclosure expectations and practices have changed accordingly. Patient preferences about disclosure when physicians discover another provider's error are unknown.

METHODS

We conducted telephone interviews beyond thematic saturation (N = 30) from January to March 2018 with patient volunteers in Michigan. Participants responded to 2 medical error vignettes, the first involving a single physician discovering their own error, and the second involving an IMED scenario. Interviews were conducted concurrently with thematic coding, coded independently by 2 investigators, and discussed until consensus was reached. Analysis proceeded after the inductive and comparative approach of interpretive description.

RESULTS

Patients considered IMED essentially equivalent to self-discovered errors, and strongly preferred disclosure in both scenarios. Patients preferred disclosure for a variety of reasons, most commonly describing an inherent value in knowing about their own health, a belief that physicians should practice honesty and transparency, and a desire to participate in future care in an informed manner. Patients said they would likely take certain actions after disclosure of another physician's error, ranging from confronting the responsible physician to changing providers to pursuing legal action, with the latter being only in cases of irreversible and debilitating errors.

CONCLUSIONS

This study explores a new domain within the field of error disclosure, concluding that patients preferred disclosure of errors in cases of IMED. Overall, these findings provide motivation to devise systems-level solutions to enable and facilitate IMED disclosure.

Women Surgeons' Perspectives on System-level Strategies to Address Interpersonal Workplace Conflict

OBJECTIVE

We sought to gain a comprehensive understanding of the current methods for conflict resolution and the ways in which women surgeons would prefer workplace conflicts to be adjudicated.

SUMMARY OF BACKGROUND DATA

Interprofessional workplace conflicts are poorly studied, particularly for women in surgery. These conflicts may negatively impact surgical team dynamic and be detrimental to patient safety. Moreover, workplace conflicts and their management are a proposed driver of decreased professional satisfaction and achievement. How women surgeons experience workplace conflicts and how these are managed remains unexplored.

METHODS

We conducted 30 semi-structured interviews with women surgeons across the United States who had experienced workplace conflict that resulted in action by a nonphysician. Surgeons were diverse with respect to demographics, specialty, and institutional settings. Through thematic analysis using NVivo, we analyzed and reported patterns within the data.

RESULTS

Although the majority of women asserted resilience in how they engage with these situations, many also cited ways in which these events could better be adjudicated. Recommendations included (1) more direct conflict resolution, (2) more transparency in reporting processes, (3) greater opportunity to address complaints, (4) explicit policies for events that repeatedly result in workplace conflict, and (5) divorcing interpersonal complaints from patient safety reporting mechanisms.

CONCLUSION

This study motivates and informs best practices around adjudication of workplace conflict to help protect women surgeons and nonclinicians. Going forward, best practices should include more objective criteria for how conflicts are adjudicated. Continued efforts at an institutional level are needed to help mitigate inequities against women surgeons.

Trends in Contralateral Prophylactic Mastectomy Utilization for Small Unilateral Breast Cancer

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Trends in Breast Cancer Treatment De-Implementation in Older Patients with Hormone Receptor-Positive Breast Cancer: A Mixed Methods Study

INTRODUCTION

Guidelines allow for the omission of sentinel lymph node biopsy (SLNB) and post-lumpectomy radiotherapy in women ≥ 70 years of age with hormone receptor-positive (HR +) breast cancer. Despite this, national data suggest these procedures have not been widely de-implemented.

OBJECTIVES

Our objectives were to evaluate trends in SLNB and post-lumpectomy radiotherapy utilization in patients who are eligible for omission, and evaluate patient preferences as a target for de-implementation of low-value care.

METHODS

We performed a sequential explanatory mixed-methods study by first analyzing an institutional database of patients ≥ 70 years of age with HR + breast cancer who received surgical treatment from 2014 to 2018. Based on the quantitative data, we conducted semi-structured interviews with women identified as high or low utilizers of breast cancer treatments to elicit patient perspectives on de-implementation.

RESULTS

SLNB and post-lumpectomy radiotherapy were performed in 68% and 43% of patients, respectively, who met the criteria for omission. There was a significant decrease in SLNB rates from 2014 to 2018. Forty-nine percent of patients were classified as high utilizers and 26% were classified as low utilizers. Qualitative analysis found that the most important factors influencing decision making regarding SLNB and post-lumpectomy radiotherapy omission for both high and low utilizers were trust in their provider and a desire for peace of mind.

CONCLUSIONS

Despite efforts to de-implement low-value care, older women with HR + breast cancer remain at risk of overtreatment. Patient perspectives suggest that multi-level de-implementation strategies will need to target provider practice patterns and patient-provider communication to promote high-quality decision making and reduction in breast cancer overtreatment.

Impact of Breast Cancer Pretreatment Nodal Burden and Disease Subtype on Axillary Surgical Management

BACKGROUND

The management of clinically node-positive breast cancer after neoadjuvant chemotherapy (NAC) has progressed with the potential to avoid the morbidity of axillary lymph node dissection in patients with complete response to therapy. This study addresses the impact of pretreatment nodal burden and tumor subtype on axillary pathologic complete response (AXpCR) in patients treated with NAC to better inform axillary surgical management.

METHODS

A prospective database was reviewed to identify clinically node-positive patients who underwent NAC followed by axillary lymph node dissection. Patients were stratified in accordance with abnormal nodal burden on pretreatment axillary imaging defined as low (1-2 nodes) or high (≥3 nodes), and biologic subtype defined by hormone receptor (HR+, HR-) and HER2 (human epidermal growth factor receptor 2) status. The primary outcome was AXpCR.

RESULTS

AXpCR was 43% in the study population. There was no difference in AXpCR between low and high nodal burden groups (44% versus 42%, P = 0.87). Subtype correlated to AXpCR (P < 0.001) with the highest rate (78%) in the HR-/HER2+ group. Overall, HER2+ patients had a significantly higher AXpCR than HER2- subtypes (66% versus 28% P < 0.001). HR and HER2 status were also predictive of AXpCR when comparing patient, tumor, and treatment variables.

CONCLUSIONS

Biologic subtype better correlated with rates of AXpCR than nodal burden alone with the highest rates of AXpCR in HER2+ patients. Consideration of tumor biology is more informative than nodal burden when evaluating options for axillary management after NAC.

Opioid prescribing exceeds consumption following common surgical oncology procedures

BACKGROUND AND OBJECTIVES

Surgical oncology patients are vulnerable to persistent opioid use. As such, we aim to compare opioid prescribing to opioid consumption for common surgical oncology procedures.

METHODS

We prospectively identified patients undergoing common surgical oncology procedures at a single academic institution (August 2017-March 2018). Patients were contacted by telephone within 6 months of surgery and asked to report their opioid consumption and describe their discharge instructions and opioid handling practices.

RESULTS

Of the 439 patients who were approached via telephone, 270 completed at least one survey portion. The median quantity of opioid prescribed was significantly larger than consumed following breast biopsy (5 vs. 2 tablets of 5 mg oxycodone, p < .001), lumpectomy (10 vs. 2 tablets of 5 mg oxycodone, p < .001), and mastectomy or wide local excision (20 tablets vs. 2 tablets of 5 mg oxycodone, p < .001). The majority of patients reported receiving education on taking opioids, but only 27% received instructions on proper disposal; 82% of prescriptions filled resulted in unused opioids, and only 11% of these patients safely disposed of them.

CONCLUSIONS

This study demonstrates that opioid prescribing exceeds consumption following common surgical oncology procedures, indicating the potential for reductions in prescribing.

Women Surgeons' Experiences of Interprofessional Workplace Conflict

IMPORTANCE

Gender differences in interprofessional conflict may exist and precipitate differential achievement, wellness, and attrition in medicine.

OBJECTIVE

Although substantial attention and research has been directed toward improving gender equity in surgery and addressing overall physician wellness, research on the role of interprofessional conflict has been limited. The objective of this study was to understand scenarios driving interprofessional conflict involving women surgeons, the implications of the conflict on personal, professional, and patient outcomes, and how women surgeons navigate conflict adjudication.

DESIGN, SETTING, AND PARTICIPANTS

A qualitative approach was used to explore the nature, implications, and ways of navigating interprofessional workplace conflict experienced by women surgeons. The setting was a national sample of US women surgeons. Purposive and snowball sampling were used to recruit women surgeons in training or practice from annual surgical society meetings. Participants were eligible if they were currently in a surgical training program or surgical practice. Nearly all participants had experienced at least 1 workplace conflict with a nonphysician staff member resulting in a formal write-up.

EXPOSURES

A workplace conflict was defined as any conflict resulting in the nonphysician staff member taking action such as confronting the woman surgeon, reporting the event to supervisors, or filing a formal report.

MAIN OUTCOMES AND MEASURES

Interviews were conducted between February 19, 2019, and June 21, 2019. Recordings were transcribed and deidentified. Inductive thematic analysis was used to examine data in relation to the research questions.

RESULTS

Thirty US women surgeons (8 [27%] age 25-34 years, 16 [53%] age 35-44 years, 5 [17%] age 45-54 years, and 1 [3%] age 55-64 years) of varying surgical specialties were interviewed. Conflicts were often reported as due to a breakdown in communication or from performance-related disputes. Participants perceived personal and professional implications including self-doubt, depression, frustration, anxiety, loss of sleep, reputational harms, and delays to advancement. Participants also described potential patient safety implications primarily due to decreased communication resulting from some surgeons being hesitant to engage in subsequent interactions. Participants described a variety of navigation strategies including relationship management, rapport building, and social capital. The success of these processes tended to vary by individual circumstances, including the details of the conflict, practice setting, level of support of leadership, and individual personality of the surgeon.

CONCLUSIONS AND RELEVANCE

This qualitative study highlights women surgeons' experiences with interprofessional workplace conflict. Interprofessional culture building, broader dissemination of implicit bias training, and transparent and equitable adjudication systems are potential strategies for avoiding or mitigating the implications of these conflicts.

Management of the positive sentinel lymph node in the post-MSLT-II era

BACKGROUND AND OBJECTIVES

The publication of MSLT-II shifted recommendations for management of sentinel lymph node biopsy positive (SLNB+) melanoma to favor active surveillance. We examined trends in immediate completion lymph node dissection (CLND) following publication of MSLT-II.

METHODS

Using a prospective melanoma database at a high-volume center, we identified a cohort of consecutive SLNB+ patients from July 2016 to April 2019. Patient and disease characteristics were analyzed with multivariate logistic regression to examine factors associated with CLND.

RESULTS

Two hundred and thirty-five patients were included for analysis. CLND rates were 67%, 33%, and 26% for the year before, year after, and second-year following MSLT-II. Factors associated with undergoing CLND included primary located in the head and neck (59% vs 33%, P = .003 and odds ratio [OR], 5.22, P = .002) and higher sentinel node tumor burden (43% vs 10% for tumor burden ≥0.1 mm, P < .001 and OR, 8.64, P = .002).

CONCLUSIONS

Rates of CLND in SLNB+ melanoma decreased dramatically, albeit not uniformly, following MSLT-II. Factors that increased the likelihood of immediate CLND were primary tumor located in the head and neck and high sentinel node tumor burden. These groups were underrepresented in MSLT-II, suggesting that clinicians are wary of implementing active surveillance recommendations for patients perceived as higher risk.

Patient Perspectives on Treatment Options for Older Women With Hormone Receptor-Positive Breast Cancer: A Qualitative Study

Importance

Women aged 70 years or older with hormone receptor-positive breast cancer have an excellent prognosis, but because of their age and comorbidities, they are at higher risk for treatment-related adverse events. Despite studies demonstrating the safety of omitting previously routine therapies, including sentinel lymph node biopsy (SLNB) and postlumpectomy radiotherapy, these treatments continue to be used at high rates. Physicians cite patient preference as one factor associated with overuse. However, little is known about how women view potential de-escalation of therapies.

Objective

To evaluate older women's preferences for SLNB and radiotherapy in the setting of guidelines recommending them or allowing for their omission.

Design, Setting, and Participants

This qualitative study was performed from October 2019 to January 2020. Midwestern women aged 70 years and older who had never received a diagnosis of breast cancer were recruited online and interviewed. Guided by an interpretive description approach, interviews were analyzed to produce a thematic description. Data analysis was performed from January to March 2020.

Exposures

Participants were presented with hypothetical scenarios in which they received a diagnosis of low-risk, hormone receptor-positive breast cancer and were given treatment options in accordance with current guidelines.

Main Outcomes and Measures

The interviews elicited perspectives on breast cancer treatment, including surgery, SLNB, chemotherapy, and postlumpectomy radiotherapy.

Results

The median (interquartile range) age of the 30 participants was 72.0 (71.0-76.5) years. Most of the women were White (26 participants [87%]), lived in metropolitan areas (29 participants [97%]), and were college educated (20 participants [67%] had a 4-year degree or higher). Overall, women expressed the belief that age-based guidelines were appropriate on the basis of decreased recurrence risk and increased frailty in older patients. However, many participants stated that these guidelines should not apply to healthy older women with a long life expectancy. Some participants struggled to understand that the basis for treatment de-escalation in older patients is a favorable, not poor, prognosis. Women who said they would undergo SLNB (12 participants [40%]) perceived the procedure as low risk and providing peace of mind. Most participants (22 participants [73%]) expressed a preference for omitting postlumpectomy radiotherapy because of the perceived risks, lack of benefit, and inconvenience.

Conclusions and Relevance

Positive reframing of the excellent prognosis driving national recommendations for de-escalation may reduce breast cancer overtreatment in older women. Strategies for reducing SLNB use will likely require education on the risks vs benefits and addressing patient preferences for peace of mind. In contrast, efforts to reduce radiotherapy use may need to address clinician or organizational factors.

Deimplementation of the Choosing Wisely Recommendations for Low-Value Breast Cancer Surgery

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.

Medical error professionals' perspectives on Inter-system Medical Error Discovery (IMED): Consensus, divergence, and uncertainty

Best practices for how to respond are unclear when a medical error is discovered in a different system (inter-system medical error discovery or IMED). This qualitative study explored medical error professionals' views on disclosure, feedback, and reporting in these scenarios.We conducted semi-structured telephone interviews from January to September 2018 with 15 medical error professionals from 5 regions of the United States. Interview guides addressed perspectives on best practice, minimum obligations, and mediating factors with respect to IMED. Each transcript was coded independently by two investigators. Analysis followed the inductive approach of interpretive description.Medical error professionals expressed diverse views about minimum obligations and best practices for physicians when responding to IMED events. All cited practical barriers to disclosure, feedback, and reporting in these scenarios. There was general consensus that clear-cut, harmful errors should be disclosed to patients, and most advised investigation and feedback prior to disclosure. Respondents diverged in recommended best practices and thresholds for taking action. All noted the lack of guidance specific to IMED scenarios but differed in how they would extrapolate from more general guidance.While medical error professionals expressed consensus regarding obligations to disclose obvious errors, they differed on particulars. Guidelines or an algorithm could be very useful. Efforts to develop clear guidelines for IMED must take into account these factors, as well as practical and political challenges to communication about errors discovered across systems.

Gaps in Online Breast Cancer Treatment Information for Older Women

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.

Medical Maximizing-Minimizing Preferences in Relation to Low-Value Services for Older Women with Hormone Receptor-Positive Breast Cancer: A Qualitative Study

BACKGROUND

Multiple studies have demonstrated the safety of omitting therapies in older women with breast cancer. Despite de-implementation guidelines, up to 65% of older women continue to receive one or more of these low-value services. Previous work has investigated the role of both provider and patient attitudes as barriers to de-implementation; however, the importance of the patient's maximizing-minimizing preferences within this context remains unclear.

METHODS

In this qualitative study, we conducted 30 semi-structured interviews with women ≥ 70 years of age without a previous diagnosis of breast cancer to elicit perspectives on breast cancer treatment in relation to their medical maximizing-minimizing preferences, as determined by the single-item maximizer-minimizer elicitation question (MM1). We used an interpretive description approach in analysis to produce a thematic survey.

RESULTS

Participants were relatively evenly distributed across the MM1 (minimizer, n = 8; neutral, n = 13; maximizer, n = 9). Despite being told of recommendations allowing for the safe omission of sentinel lymph node biopsy and post-lumpectomy radiotherapy, maximizers consistently stated preferences for more medical intervention and aggressive therapies over minimizers and neutral individuals.

CONCLUSION

Medical maximizing-minimizing preferences in older women correspond with preferences for breast cancer treatment options that guidelines identify as potentially unnecessary. Increased awareness of patient-level variability in maximizing-minimizing preferences may be valuable in developing optimal intervention strategies to reduce utilization of low-value care.
