Unpacking overuse of androgen deprivation therapy for prostate cancer to inform de-implementation strategies.

BACKGROUND: Many men with prostate cancer will be exposed to androgen deprivation therapy (ADT). While evidence-based ADT use is common, ADT is also used in cases with no or limited evidence resulting in more harm than benefit, i.e., overuse. Since there are risks of ADT (e.g., diabetes, osteoporosis), it is important to understand the behaviors facilitating overuse to inform de-implementation strategies. For these reasons, we conducted a theory-informed survey study, including a discrete choice experiment (DCE), to better understand ADT overuse and provider preferences for mitigating overuse. METHODS: Our survey used the Action, Actor, Context, Target, Time (AACTT) framework, the Theoretical Domains Framework (TDF), the Capability, Opportunity, Motivation-Behavior (COM-B) Model, and a DCE to elicit provider de-implementation strategy preferences. We surveyed the Society of Government Service Urologists listserv in December 2020. We stratified respondents based on the likelihood of stopping overuse as ADT monotherapy for localized prostate cancer ("yes"/"probably yes," "probably no"/"no"), and characterized corresponding Likert scale responses to seven COM-B statements. We used multivariable regression to identify associations between stopping ADT overuse and COM-B responses. RESULTS: Our survey was completed by 84 respondents (13% response rate), with 27% indicating "probably no"/"no" to stopping ADT overuse. We found differences across respondents who said they would and would not stop ADT overuse in demographics and COM-B statements. Our model identified 2 COM-B domains (Opportunity-Social, Motivation-Reflective) significantly associated with a lower likelihood of stopping ADT overuse. Our DCE demonstrated in-person communication, multidisciplinary review, and medical record documentation may be effective in reducing ADT overuse. CONCLUSIONS: Our study used a behavioral theory-informed survey, including a DCE, to identify behaviors and context underpinning ADT overuse. Specifying behaviors supporting and gathering provider preferences in addressing ADT overuse requires a stepwise, stakeholder-engaged approach to support evidence-based cancer care. From this work, we are pursuing targeted improvement strategies. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03579680.

Understanding Treatment Decision-Making in Older Women With Breast Cancer: A Survey-Based Study.

INTRODUCTION: For women ≥70 y old with early-stage hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer, the national guidelines recommend the omission of sentinel lymph node biopsy (SLNB) and post-lumpectomy radiotherapy. However, national-level data suggest these treatments remain common. We utilized a survey-based approach to explore patient-level factors driving overutilization. METHODS: We recruited women ≥70 y old with early-stage hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer within 6 mo of surgery. An exploratory cross-sectional survey captured information on offered and pursued treatments, the importance of patient-centered outcomes, and the influence of each outcome on treatment decision-making. Descriptive statistics were used for analysis. RESULTS: 31/51 patients completed the survey with a response rate of 61%. Most patients (86%) received a lumpectomy. Twenty-eight percent of patients received SLNB, and 56% of lumpectomy patients underwent adjuvant radiotherapy. When considering treatment options, the patient-centered outcomes, most important for decision-making, were overall survival, breast-specific survival, and preventing local recurrence, while breast appearance, financial costs, and avoiding the need for pills (endocrine therapy) were the least important. CONCLUSIONS: Patients' treatment decisions align with their values. The correlation between patient-stated values and treatment decisions suggests a perceived mortality benefit of low-value SLNB and radiotherapy. These findings can inform targeted efforts to deimplement low-value care in breast cancer through patient-focused tools and education.

Behavioral Interventions on Surgeons' Preoperative Decision-Making: A Scoping Review and Critical Analysis.

INTRODUCTION: Consensus is lacking regarding the optimal strategy to influence surgeons' behaviors to reduce low-value surgical care. Comprehensively describing the existing body of literature that seeks to intervene on surgeons' preoperative decision-making may aid in structuring future behavior change strategies. METHODS: We performed a scoping review using four databases (Medical Literature Analysis and Retrieval System Online, Embase, Web of Science, and Cumulated Index to Nursing and Allied Health Literature) for articles that tested the effect of behavioral-based interventions on any aspect of surgeons' decision-making in the preoperative setting. Abstracted data were characterized by summative descriptions and analyzed using the Tailored Implementation for Chronic Disease framework, mapping aspects of deimplementation strategies in the studies onto the determinant(s) that they altered. Data abstraction and mapping tools were piloted and iteratively revised before two researchers independently assessing studies and categorizing determinants, and then meeting to discuss their decisions. RESULTS: There were 1460 articles identified from the initial search, with 17 full text articles ultimately included in the scoping review. Eight studies relied on a multidisciplinary preoperative conference to accomplish their aims, while five were multifaceted in their approach to deimplementation, and four studies used only a clinical decision support tool to accomplish their aims. Mapping determinants addressed in these studies onto the Tailored Implementation for Chronic Disease framework demonstrated that most strategies attempted to close knowledge gaps, leverage communication between providers, and broadcast institutional prioritization of change. CONCLUSIONS: There is a small but growing field of implementation and deimplementation strategies in preoperative surgical decision-making, and different approaches may be equally effective in varied clinical contexts. Deliberate measurement and comparison of outcomes, as well as selection of control groups, are areas for improvement in future work.

Targets for De-implementation of Unnecessary Testing Before Low-Risk Surgery: A Qualitative Study.

INTRODUCTION: Despite multispecialty recommendations to avoid routine preoperative testing before low-risk surgery, the practice remains common and de-implementation has proven difficult. The goal of this study as to elicit determinants of unnecessary testing before low-risk surgery to inform de-implementation efforts. METHODS: We conducted focused ethnography at a large academic institution, including semi-structured interviews and direct observations at two preoperative evaluation clinics and one outpatient surgery center. Themes were identified through narrative thematic analysis and mapped to a comprehensive and integrated checklist of determinants of practice, the Tailored Implementation for Chronic Diseases framework (TICD). RESULTS: Thirty individuals participated (surgeons, anesthesiologists, primary care physicians, physician assistants, nurses, and medical assistants). Three themes were identified: (1) Shared Values (TICD Social, Political, and Legal Factors), (2) Gaps in Knowledge (TICD Individual Health Professional Factors, Guideline Factors), and (3) Communication Breakdown (TICD Professional Interactions, Incentives and Resources, Capacity for Organizational Change). Shared Values describe core tenets expressed by all groups of clinicians, namely prioritizing patient safety and utilizing evidence-based medicine. Clinicians had Gaps in Knowledge related to existing data and preoperative testing recommendations. Communication Breakdowns within interdisciplinary teams resulted in unnecessary testing ordered to meet perceived expectations of other providers. CONCLUSIONS: Clinicians have knowledge gaps related to preoperative testing recommendations and may be amenable to de-implementation efforts and educational interventions. Consensus guidelines may streamline interdisciplinary communication by clarifying interdisciplinary needs and reducing testing ordered to meet perceived expectations of other clinicians.

Incorporating Value-Based Decisions in Breast Cancer Treatment Algorithms.

Given the excellent prognosis and availability of evidence-based treatment, patients with early-stage breast cancer are at risk of overtreatment. In this review, we summarize key opportunities to incorporate value-based decisions to optimize the delivery of high-value treatment across the breast cancer care continuum.

Using Machine Learning to Predict Suitability for Surgery at an Ambulatory Surgical Center.

This Surgical Innovation describes the use of a site optimization model that uses machine learning to stratify patients according to whether they can have surgery at an ambulatory surgical center vs a hospital-based outpatient department.

Emerging From the Pandemic: How Has Academic Surgery Changed?

Academic surgery has changed along with the rest of the world in response to the COVID pandemic. With increasing rates of vaccination against COVID over the past 2 y, we have slowly but steadily made progress toward controlling the spread of the virus. Surgeons, academic surgery departments, health systems, and trainees are all attempting to establish a new normal in various domains-clinical, research, teaching, and in their personal lives. How has the pandemic changed these areas? At the 2022 Academic Surgical Congress Hot Topics session, we attempted to address these issues.

Assessing the Complex General Surgical Oncology Pipeline: Trends in Race and Ethnicity Among US Medical Students, General Surgery Residents, and Complex General Surgical Oncology Trainees.

BACKGROUND: Cancer incidence is expected to increase in coming decades, disproportionately so among minoritized communities. Racially and ethnically concordant care is essential to addressing disparities in cancer outcomes within at-risk groups. Here, we assess trends in racial and ethnic representation of medical students (MS), general surgery (GS) residents, and complex general surgical oncology (CGSO) fellows. METHODS: This is a retrospective review of data from the American Association of Medical Colleges and the Accreditation Council of Medical Education (ACGME) from 2015 to 2020. Self-reported race and ethnicity was obtained for MS, GS, and CGSO trainees. Race and ethnicity proportions were compared with respective representation in the 2020 US Census. Mann-Kendall, Wilcoxon rank sum, and linear regression were used to assess trends, as appropriate. RESULTS: A total of 316,448 MS applicants, 128,729 MS matriculants, 27,574 GS applicants, 46,927 active GS residents, 710 CGSO applicants, and 659 active CGSO fellows were included. With every progressive stage in training, there was a smaller proportion of URM active trainees than applicants. Further, URM, Hispanic/Latino, and Black/African American trainees were significantly underrepresented compared with 2020 Census data. While the proportion of White CGSO fellows increased over time (54.5-69.2%, p = 0.009), the proportion of Black/African American and Hispanic/Latino (URM) CGSO fellows did not significantly change over the study period, though URM representation was lower in 2020 as compared with 2015. DISCUSSION: From 2015 to 2020, minority representation decreased at every advancing stage in surgical oncology training. Efforts to address barriers for URM applicants to CGSO fellowships are needed.

Cognitive Bias and Dissonance in Surgical Practice: A Narrative Review.

A cognitive bias describes "shortcuts" subconsciously applied to new scenarios to simplify decision-making. Unintentional introduction of cognitive bias in surgery may result in surgical diagnostic error that leads to delayed surgical care, unnecessary procedures, intraoperative complications, and delayed recognition of postoperative complications. Data suggest that surgical error secondary to the introduction of cognitive bias results in significant harm. Thus, debiasing is a growing area of research which urges practitioners to deliberately slow decision-making to reduce the effects of cognitive bias.

Surgical Care for Racial and Ethnic Minorities and Interventions to Address Inequities: A Narrative Review.

OBJECTIVE: Racial and ethnic inequities in surgical care in the United States are well documented. Less is understood about evidence-based interventions that improve surgical care and reduce or eliminate inequities. In this review, we discuss effective patient, surgeon, community, health care system, policy, and multi-level interventions to reduce inequities and identifying gaps in intervention-based research. BACKGROUND: Evidenced-based interventions to reduce racial and ethnic inequities in surgical care are key to achieving surgical equity. Surgeons, surgical trainees, researchers, and policy makers should be aware of the evidence-based interventions known to reduce racial and ethnic disparities in surgical care for prioritization of resource allocation and implementation. Future research is needed to assess interventions effectiveness in the reduction of disparities and patient-reported measures. METHODS: We searched PubMed database for English-language studies published from January 2012 through June 2022 to assess interventions to reduce or eliminate racial and ethnic disparities in surgical care. A narrative review of existing literature was performed identifying interventions that have been associated with reduction in racial and ethnic disparities in surgical care. RESULTS AND CONCLUSIONS: Achieving surgical equity will require implementing evidenced-based interventions to improve quality for racial and ethnic minorities. Moving beyond description toward elimination of racial and ethnic inequities in surgical care will require prioritizing funding of intervention-based research, utilization of implementation science and community based-participatory research methodology, and principles of learning health systems.

Current clinical practice in the management of phyllodes tumors of the breast: an international cross-sectional study among surgeons and oncologists.

PURPOSE: Phyllodes tumors of the breast are rare fibroepithelial lesions that are classified as benign, borderline or malignant. There is little consensus on best practice for the work-up, management, and follow-up of patients with phyllodes tumors of the breast, and evidence-based guidelines are lacking. METHODS: We conducted a cross-sectional survey of surgeons and oncologists with the aim to describe current clinical practice in the management of phyllodes tumors. The survey was constructed in REDCap and distributed between July 2021 and February 2022 through international collaborators in sixteen countries across four continents. RESULTS: A total of 419 responses were collected and analyzed. The majority of respondents were experienced and worked in a university hospital. Most agreed to recommend a tumor-free excision margin for benign tumors, increasing margins for borderline and malignant tumors. The multidisciplinary team meeting plays a major role in the treatment plan and follow-up. The vast majority did not consider axillary surgery. There were mixed opinions on adjuvant treatment, with a trend towards more liberal regiments in patients with locally advanced tumors. Most respondents preferred a five-year follow-up period for all phyllodes tumor types. CONCLUSIONS: This study shows considerable variation in clinical practice managing phyllodes tumors. This suggests the potential for overtreatment of many patients and the need for education and further research targeting appropriate surgical margins, follow-up time and a multidisciplinary approach. There is a need to develop guidelines that recognize the heterogeneity of phyllodes tumors.

Survey of student mistreatment experienced during the core clinical clerkships.

BACKGROUND: The goal of this study was to learn more about the potential impact of medical student mistreatment on patient safety and care. METHODS: A web-based survey was sent to members of the class of 2021 and 2022 who have completed their core clerkships at a single academic institution. Descriptive statistics were performed to understand how prior and future mistreatment impacted communication among students and team members. RESULTS: We received 290 of 376 responses (77.1%). 26% of respondents indicated that past mistreatment negatively impacted their communication with other team members. 30% of respondents reported that fear of future mistreatment negatively impacted their communication with other team members. CONCLUSION: Mistreatment of medical students has many sources and occurs throughout the clinical curriculum. Past and fear of future student mistreatment can negatively impact intrateam communication and therefore negatively impact patient care, with the potential of causing poor patient outcomes.

International Center-Level Variation in Utilization of Completion Lymph Node Dissection and Adjuvant Systemic Therapy for Sentinel Lymph Node-Positive Melanoma at Major Referral Centers.

OBJECTIVE: The aim of this study was to determine overall trends and center-level variation in utilization of completion lymph node dissection (CLND) and adjuvant systemic therapy for sentinel lymph node (SLN)-positive melanoma. SUMMARY BACKGROUND DATA: Based on recent clinical trials, management options for SLN-positive melanoma now include effective adjuvant systemic therapy and nodal observation instead of CLND. It is unknown how these findings have shaped practice or how these contemporaneous developments have influenced their respective utilization. METHODS: We performed an international cohort study at 21 melanoma referral centers in Australia, Europe, and the United States that treated adults with SLN-positive melanoma and negative distant staging from July 2017 to June 2019. We used generalized linear and multinomial logistic regression models with random intercepts for each center to assess center-level variation in CLND and adjuvant systemic treatment, adjusting for patient and disease-specific characteristics. RESULTS: Among 1109 patients, performance of CLND decreased from 28% to 8% and adjuvant systemic therapy use increased from 29 to 60%. For both CLND and adjuvant systemic treatment, the most influential factors were nodal tumor size, stage, and location of treating center. There was notable variation among treating centers in management of stage IIIA patients and use of CLND with adjuvant systemic therapy versus nodal observation alone for similar risk patients. CONCLUSIONS: There has been an overall decline in CLND and simultaneous adoption of adjuvant systemic therapy for patients with SLN-positive melanoma though wide variation in practice remains. Accounting for differences in patient mix, location of care contributed significantly to the observed variation.

Prophylactic mastectomy and occult malignancy: Surgical and imaging considerations.

BACKGROUND: Sentinel node biopsy (SLNB) is not routinely recommended for patients undergoing prophylactic mastectomy (PM), yet omission remains a subject of debate among surgeons. A modern patient cohort was examined to determine occult malignancy (OM) incidence within PM specimens to reinforce current recommendations. METHODS: All PM performed over a 5-year period were retrospectively identified, including women with unilateral breast cancer who underwent synchronous or delayed contralateral PM or women with elevated cancer risk who underwent bilateral PM. RESULTS: The study population included 772 patients (598 CPM, 174 BPM) with a total of 39 OM identified: 17 invasive cancers (14 CPM, 3 BPM) and 22 DCIS (19 CPM, 3 BPM). Of the 86 patients for whom SLNB was selectively performed, 1 micrometastasis was identified. In the CPM cohort, risk of OM increased with age, presence of LCIS of either breast, or presence of a non-BRCA high-penetrance gene mutation, while preoperative magnetic resonance imaging was associated with lower likelihood of OM. CONCLUSIONS: Given the low incidence of invasive OM in this updated series, routine SLNB is of low value for patients undergoing PM. For patients with indeterminate radiographic findings, discordant preoperative biopsies, LCIS, or non-BRCA high-penetrance gene mutations, selective SLNB implementation could be considered.

Implementation of melanoma guidelines in the multidisciplinary setting: A qualitative analysis.

BACKGROUND: Data suggest variation in utilization of completion lymph node dissection (CLND) and adjuvant systemic therapy (AT) for sentinel lymph node-positive melanoma. We aimed to explore how clinicians consider multidisciplinary treatment options. METHODS: We conducted semi-structured interviews of surgical oncologists, medical oncologists, and otolaryngologists to produce a thematic analysis. RESULTS: Participants (n = 26) described melanoma care as inherently "multidisciplinary," noting the importance of conversations facilitated by shared clinic days or space. Despite believing that their practice mirrored other clinicians, participants revealed diverging perspectives on CLND and AT. Multidisciplinary care presented challenges for surveillance as surgeons expressed desire to retain ownership of patients but did not feel comfortable overseeing AT needs. Participants questioned the fidelity of nodal ultrasounds, noted redundancy in their roles, and described a "surveillance burden" for patients. CONCLUSION: Opportunities exist to improve multidisciplinary melanoma care through broader consensus of how to translate emerging data into patient care and delineating surveillance roles.

Surgeon Perspectives on Determinants of Same-Day Mastectomy: A Roadmap for Implementing Change.

BACKGROUND: Same-day discharge after mastectomy without immediate reconstruction (MwoR) has been shown to be safe, with improved patient satisfaction when compared with patients discharged 1 or more days after surgery. Nevertheless, only 16% of patients undergoing MwoR in Michigan are discharged on the day of surgery, with significant variation between facilities (3-88%). Our objective was to explore determinants of same-day discharge and offer strategies for broader implementation of this practice. METHODS: We conducted semi-structured interviews with surgeons performing MwoR across the state of Michigan. Recruitment utilized purposeful and snowball sampling methods. The Tailored Implementation in Chronic Disease (TICD) framework was used to inform the creation of the interview guide. Interviews were transcribed and then analyzed using directed content analysis guided by the TICD framework. Salient determinants were organized into patient, provider, and system-level factors. RESULTS: Participants (n = 26) included general surgeons, breast surgeons, and surgical oncologists. Most surgeons (n = 18, 69%) reported that they discharged fewer than 60% of patients the same day after MwoR. The most common barriers included patient knowledge at the patient level; awareness of evidence, surgeon dogma, and peer influence at the provider level; and team processes and operating room logistics at the system level. CONCLUSION: We identified surgeon-defined determinants of same-day discharge after MwoR. For the identified barriers, potential implementation strategies could include incorporation of preoperative drain teachings for patients, utilizing consensus statements and opinion leaders to disseminate evidence supporting same-day mastectomies, and conducting workshops with relevant stakeholders to establish consistent facility practice patterns among surgical teams.

Avoiding Overtreatment of Women ≥70 With Early-Stage Breast Cancer: A Provider-Level Deimplementation Strategy.

INTRODUCTION: National guidelines recommend against routine axillary staging with sentinel lymph node biopsy (SLNB) and adjuvant radiotherapy (RT) in women ≥70 y with early-stage, hormone receptor-positive, HER2-negative breast cancer and clinically negative axilla; however, these practices remain common. METHODS: We conducted a prospective pilot study from August 2021 to 2022 using an intervention targeting breast surgeons and radiation oncologists in Michigan that aimed to reduce SLNB and RT in eligible patients. The intervention consisted of (1) a geriatric assessment, (2) an assessment of the patient's medical maximizing-minimizing preferences, and (3) a tailored script with counterpoints to reasons patients commonly seek SLNB or RT. At the end of the study period, participants completed a survey providing feedback with the primary outcomes being: acceptability, appropriateness, feasibility, and intention and motivation to use the materials based on validated measures. RESULTS: Participants (n = 23) included 15 breast surgeons and 8 radiation oncologists. Collectively, the materials were used with 115 patients. Considering all materials holistically, acceptability, appropriateness, and feasibility of the intervention were high; participants also intended and were motivated to use the intervention. Scores across all measures were highest for the geriatric assessment and lowest for the tailored script. The major barriers to using the intervention were limited time and instances of disagreement on treatment recommendations among surgeons and radiation oncologists. CONCLUSIONS: The omission of SLNB and adjuvant RT should be discussed in appropriately selected patients. A multifaceted provider-level deimplementation strategy may be an effective means for achieving this goal.
