Complex cancer procedures are now performed in the ambulatory surgery setting. Remote symptom monitoring (RSM) with electronic patient-reported outcomes (ePROs) can identify patients at risk for acute hospital encounters. Defining normal recovery is needed to set patient expectations and optimize clinical team responses to manage evolving problems in real time.
To describe the patterns of postoperative recovery among patients undergoing ambulatory cancer surgery with RSM using an ePRO platform-the Recovery Tracker.
In this retrospective cohort study, patients who underwent 1 of 5 of the most common procedures (prostatectomy, nephrectomy, mastectomy, hysterectomy, or thyroidectomy) at the Josie Robertson Surgery Center at Memorial Sloan Kettering Cancer Center from September 2016 to June 2022. Patients completed the Recovery Tracker, a brief ePRO platform assessing symptoms for 10 days after surgery. Data were analyzed from September 2022 to May 2023.
Symptom severity and interference were estimated by postoperative day and procedure.
A total of 12 433 patients were assigned 110 936 surveys. Of these patients, 7874 (63%) were female, and the median (IQR) age at surgery was 57 (47-65) years. The survey response rate was 87% (10 814 patients responding to at least 1 of 10 daily surveys). Among patients who submitted at least 1 survey, the median (IQR) number of surveys submitted was 7 (4-8), and each assessment took a median (IQR) of 1.7 (1.2-2.5) minutes to complete. Symptom burden was modest in this population, with the highest severity on postoperative days 1 to 3. Pain was moderate initially and steadily improved. Fatigue was reported by 6120 patients (57%) but was rarely severe. Maximum pain and fatigue responses (very severe) were reported by 324 of 10 814 patients (3%) and 106 of 10 814 patients (1%), respectively. The maximum pain severity (severe or very severe) was highest after nephrectomy (92 of 332 [28%]), followed by mastectomy with reconstruction (817 of 3322 [25%]) and prostatectomy (744 of 3543 [21%]). Nausea (occasionally, frequently, or almost constantly) was common and experienced on multiple days by 1485 of 9300 patients (16%), but vomiting was less common (139 of 10 812 [1%]). Temperature higher than 38 °C was reported by 740 of 10 812 (7%). Severe or very severe shortness of breath was reported by 125 of 10 813 (1%).
Defining detailed postoperative symptom burden through this analysis provides valuable data to inform further implementation and maintenance of RSM programs in surgical oncology patients. These data can enhance patient education, set expectations, and support research to allow iterative improvement of clinical care based on the patient-reported experience after discharge.
Entrustable Professional Activities in Surgery: A Review.
JAMA SurgeryEntrustable professional activities (EPAs) compose a competency-based education (CBE) assessment framework that has been increasingly adopted across medical specialties as a workplace-based assessment tool. EPAs focus on directly observed behaviors to determine the level of entrustment a trainee has for a given activity of that specialty. In this narrative review, we highlight the rationale for EPAs in general surgery, describe current evidence supporting their use, and outline some of the practical considerations for EPAs among residency programs, faculty, and trainees.
An expanding evidence base for EPAs in general surgery has provided moderate validity evidence for their use as well as practical recommendations for implementation across residency programs. Challenges to EPA use include garnering buy-in from individual faculty and residents to complete EPA microassessments and engage in timely, specific feedback after a case or clinical encounter. When successfully integrated into a program's workflow, EPAs can provide a more accurate picture of residents' competence for a fundamental surgical task or activity compared with other assessment methods.
EPAs represent the next significant shift in the evaluation of general surgery residents as part of the overarching progression toward CBE among all US residency programs. While pragmatic challenges to the implementation of EPAs remain, the best practices from EPA and other CBE assessment literature summarized in this review may assist individuals and programs in implementing EPAs. As EPAs become more widely used in general surgery resident training, further analysis of barriers and facilitators to successful and sustainable EPA implementation will be needed to continue to optimize and advance this new assessment framework.

National data on the development of competence during training have been reported using the Accreditation Council for Graduate Medical Education (ACGME) Milestones system. It is now possible to consider longitudinal analyses that link Milestone ratings during training to patient outcomes data of recent graduates.
To evaluate the association of in-training ACGME Milestone ratings in a surgical specialty with subsequent complication rates following a commonly performed operation, endovascular aortic aneurysm repair (EVAR).
This study of patient outcomes followed EVAR in the Vascular Quality Initiative (VQI) registry (4213 admissions from 208 hospitals treated by 327 surgeons). All surgeons included in this study graduated from ACGME-accredited training programs from 2015 through 2019 and had Milestone ratings 6 months prior to graduation. Data were analyzed from December 1, 2021, through September 15, 2023. Because Milestone ratings can vary with program, they were corrected for program effect using a deviation score from the program mean.
Milestone ratings assigned to individual trainees 6 months prior to graduation, based on judgments of surgical competence.
Surgical complications following EVAR for patients treated by recent graduates during the index hospitalization, obtained using the nationwide Society for Vascular Surgery Patient Safety Organization's VQI registry, which includes 929 participating centers in 49 US states.
The study included outcomes for 4213 patients (mean [SD] age, 73.25 [8.74] years; 3379 male participants [80.2%]). Postoperative complications included 9.5% major (400 of 4213 cases) and 30.2% minor (1274 of 4213 cases) complications. After adjusting for patient risk factors and site of training, a significant association was identified between individual Milestone ratings of surgical trainees and major complications in early surgical practice in programs with lower mean Milestone ratings (odds ratio, 0.50; 95% CI; 0.27-0.95).
In this study, Milestone assessments of surgical trainees were associated with subsequent clinical outcomes in their early career. Although these findings represent one surgical specialty, they suggest Milestone ratings can be used in any specialty to identify trainees at risk for future adverse patient outcomes when applying the same theory and methodology. Milestones data should inform data-driven educational interventions and trainee remediation to optimize future patient outcomes.

Comprehensive Young Age Breast Cancer registry from clinical, genomics, and patient-reported outcomes measured with 15 years follow-up: the CHARM cohort profile.
Breast CancerIn recognition of the distinct clinical challenges and research gaps in young breast cancer (YBC) patients, we established the Comprehensive Young Age Breast Cancer (CHARM) registry to collect prospective data.
This prospective cohort included patients who were newly diagnosed with histologically confirmed breast cancer without prior treatment at the Samsung Medical Center (SMC) in April 2013. We included patients who were either 40 years old or younger at the time of diagnosis, pregnant at breast cancer diagnosis or diagnosed with breast cancer within 1 year of delivery. All data were collected using Medidata's Rave Electronic Data. Clinical data were obtained from electronic medical records. Two experienced pathologists reviewed the pathologic data. Bone mineral densitometry tests have been conducted annually. To obtain multi-omics data, tumor tissues and blood samples were prospectively collected from consenting patients in the registry during surgery. The fertility-related factor also collected collaborated with the Department of Obstetrics and Gynecology. Anti-Müllerian hormone, estradiol, follicle-stimulating hormone, and luteinizing hormone levels were measured using an additional blood sample from baseline to last follow-up. Patient-reported outcomes were assessed using mobile questionnaires.
A total of 1868 participants were included in the SMC YBC study. The average (standard deviation) age was 35.57 (3.79) and 99.8% of the participants were premenopausal. Among them, 1062 participants completed the PRO questionnaires.
The SMC YBC cohort serves as a comprehensive registry for YBC to optimize care and improve knowledge regarding the management of YBC.

Collaborative Approach toward Transplant Candidacy for Obese End-Stage Renal Disease Patients.
American College of SurgeonsAn elevated Body Mass Index (BMI) is a major cause of transplant preclusion for patients with End Stage Renal Disease (ESRD). This phenomenon exacerbates existing socioeconomic and racial disparities and increases the economic burden of maintaining patients on dialysis. Metabolic Bariatric Surgery (MBS) in such patients is not widely available. Our center created a collaborative program to undergo weight loss surgery before obtaining a kidney transplant.
We studied the outcomes of these patients post MBS and transplant surgery. One hundred and eighty-three ESRD patients were referred to the bariatric team by the transplant team between Jan 2019 through June 2023. Of these, 36 underwent MBS (20 RYGB, 16 SG), and 10 underwent subsequent transplantation, with another 15 currently waitlisted. Both surgical teams shared resources, including dieticians, social workers, and a common database, for easy transition between teams.
The mean starting BMI for all referrals was 46.4 kg/m2 and was 33.9 kg/m2 at the time of transplant. The average number of hypertension medications decreased from 2.0 (range 2.0 to 4.0) pre-surgery to 1.0 (range 1.0 to 3.0) post-surgery. Similarly, HbA1C levels improved, with pre-operative averages at 6.2 (range 5.4 to 7.6) and postoperative levels at 5.2 (range 4.6 to 5.8) All transplants are currently functioning, with a median creatinine of 1.5 (1.2 - 1.6) mg/dl (GFR 46 (36.3 - 71.0)).
A collaborative approach between bariatric and transplant surgery teams offers a pathway toward transplant for obese ESRD patients, and potentially alleviates existing healthcare disparities. ESRD patients that undergo MBS have unique complications to be aware of. The improvement in comorbidities may lead to superior post-transplant outcomes.
Barriers to Black Medical Students and Residents Pursuing and Completing Surgical Residency in Canada: A Qualitative Analysis.
American College of SurgeonsThe limited available data suggest that the Canadian surgical workforce does not reflect the racial diversity of the patient population it serves, despite the well-established benefits of patient-provider race concordance. There have been no studies to date that characterize the systemic and individual challenges faced by Black medical students in matching to and successfully finishing training in a surgical specialty within a Canadian context that can explain this underrepresentation.
Using critical qualitative inquiry and purposive sampling to ensure gender, geographical, and student/trainee year heterogeneity, we recruited self-identifying Black medical students and surgical residents across Canada. Online in-depth semi-structured interviews were conducted and transcribed verbatim. Transcripts were analyzed through an inductive reflexive narrative thematic process by four analysts.
27 participants including 18 medical students and 9 residents, were interviewed. The results showed three major themes that characterized their experiences: journey to and through medicine, perceptions of the surgical culture, and recommendations to improve the student experience. Medical students identified lack of mentorship and representation, as well as experiences with racism as the main barriers to pursuing surgical training. Surgical trainees cited systemic racism, lack of representation and insufficient safe spaces as the key deterrents to program completion. The intersection with gender exponentially increased these identified barriers.
Except for a few surgical programs, medical schools across Canada do not offer a safe space for Black students and trainees to access and complete surgical training. An urgent change is needed to provide diverse mentorship that is transparent, acknowledges the real challenges related to systemic racism and biases, and is inclusive of different racial and ethnic backgrounds.
A prospective comparison study utilizing patient-reported outcomes of taxane-related peripheral neuropathy between nab-paclitaxel and standard paclitaxel in patients with breast cancer.
Breast CancerBACKGROUND: Characteristics of taxane-induced peripheral neuropathy (PN) could be different between paclitaxel and nab-paclitaxel. The purpose of this prospective observational multicenter cohort study was to compare tri-weekly nab-paclitaxel to weekly standard paclitaxel regarding the severity, onset and recovery of sensory and motor PN in patients with breast cancer.
Patients with histologically confirmed breast cancer who were scheduled to receive standard weekly paclitaxel (80 mg/m2) or tri-weekly nab-paclitaxel (260 mg/m2) at institutions in our multicenter group were eligible for this study. Sensory and motor PN were evaluated every 3 weeks until PN improved for up to one year using patient-reported outcome.
Between February 2011 and April 2013, 115 patients were enrolled, including 57 and 58 in the paclitaxel and nab-paclitaxel groups, respectively. The incidence of moderate or severe sensory PN was not significantly different between the two groups (p = 0.40). The incidence of moderate or higher motor PN was more frequent in the nab-paclitaxel group than in the paclitaxel group (p = 0.048). The median period for demonstrating PN were shorter in the nab-paclitaxel group than in the paclitaxel group (sensory, p = 0.003; motor, p = 0.001). The recovery of motor PN was slower in the nab-paclitaxel group than in the paclitaxel group (p = 0.035), while the recovery period of sensory PN was not statistically different.
Nab-paclitaxel induced sensory PN sooner than paclitaxel, and no difference was observed in the severity and recovery duration between the two agents. Motor PN was more severe, started sooner, and improved over a longer period in the nab-paclitaxel-treated patients than in the paclitaxel-treated patients.
Correlation between postoperative treatment selection and prognosis determined using the Oncotype DX® test data: a retrospective multicenter study in Japan.
Breast CancerOncotype DX® is a frequently used multigene assay for hormone receptor-positive breast cancers. However, limited evidence is available regarding its application in Japan owing to the lack of insurance coverage. Therefore, we conducted this large-scale, retrospective study by collecting data from nine Japanese institutes and assessed postoperative treatment choice and prognosis by using Oncotype DX®.
Six hundred thirty-two patients who underwent breast surgery and whose recurrence score (RS) data were available were included. They were divided into RS 0-25 and RS ≥ 26 groups. The groups were compared in terms of clinicopathological factors, treatment options, and prognosis.
After the median follow-up period of 10.1 years, the disease-free survival (DFS) rates were significantly better in the RS 0-25 group (p = 0.02). Per the recurrent event type, there was no significant intergroup difference in locoregional recurrence (p = 0.139). However, a trend toward better distant DFS was observed in the RS 0-25 group (p = 0.08). Overall survival was also significantly better in this group (p = 0.027). Considering chemotherapy use, DFS worsened among chemotherapy-treated patients with an RS of 0-25 and those with an RS ≥ 26 who did not receive chemotherapy (p < 0.001). Seven (1.35%) chemotherapy-treated patients with an RS of 0-25 showed disease recurrence.
This study presents the largest database-derived prognostic data in Japanese patients, utilizing the Oncotype DX® treatment selection. Further studies are needed to determine the impact on treatment choice, considering the clinical risk, and the need for additional postoperative treatment.
