Case Volume Is Not Associated With Outcomes After Adrenalectomy Performed by Urologic Surgeons.

INTRODUCTION: Our goal was to compare outcomes of adrenalectomy performed by low-volume and high-volume academic urologists with extensive experience in renal surgery. METHODS: A single-center retrospective review identified patients undergoing adrenalectomy by urologists from 2009 to 2023. Data were gathered on demographics, tumor characteristics, surgeon volume, surgical outcomes including length of procedure, estimated blood loss, length of stay, and complications identified by the Clavien-Dindo complication classification system. Bivariable and multivariable analyses adjusting for BMI, size of mass, age, and surgical approach compared outcomes between low- and high-volume adrenalectomy surgeons. RESULTS: A total of 304 adrenalectomies were performed by 7 urologic surgeons during the study period. One surgeon was high volume, with an average of 15 adrenalectomies per year during the study period. The remaining 6 surgeons ranged from < 1 to 4 adrenalectomies per year on average during the study period and were considered low volume. On multivariable analysis, the rate of any complication was found to be significantly different between the groups (5.3% vs 13.5%, P = .01). However, on analysis of Clavien 3 or higher complications, the rate was not found to be different (1% vs 4%, P = .22). Procedure time (130 vs 134 minutes, P = .33), estimated blood loss (30 vs 50 mL, P = .86), positive margin rate (11% vs 7%, P = .35), and length of stay (2 days vs 2 days, P = .22) were not different when the surgery was performed by a high-volume or low-volume urologist. CONCLUSIONS: Surgical volume may not affect outcomes of adrenalectomy when performed by urologists experienced in retroperitoneal surgery at a high-volume, specialized center.

Following carpel tunnel release, what factors affect whether patients return to the same or different hand surgeon for a subsequent procedure?

BACKGROUND: Following carpal tunnel release (CTR), patients may be indicated for subsequent hand surgery (contralateral CTR and/or trigger finger release [TFR]). While surgeons typically take pride in patient loyalty, the rate of returning to the same hand surgeons has not been previously characterized. METHODS: Patients undergoing CTR were isolated from 2010-2021 PearlDiver M151 dataset. Subsequent CTR or TFR were identified and characterized as being performed by the same or different surgeon, with patient factors associated with changing to a different surgeon determined by multivariable analyses. RESULTS: In total, 1,121,922 CTR patients were identified. Of these, subsequent surgery was identified for 307,385 (27.4%: CTR 289,455 [94.2%] and TFR 17,930 [5.8%]). Of the patients with a subsequent surgery, 257,027 (83.6%) returned to the same surgeon and 50,358 (16.4%) changed surgeons. Multivariable analysis found factors associated with changing surgeon (in order of decreasing odds ration [OR]) to be: TFR as the second procedure (OR 2.98), time between surgeries greater than 2-years (OR 2.30), Elixhauser-Comorbidity Index (OR 1.14 per 2-point increase), and male sex (OR 1.06), with less likely hood of changing for those with Medicare (OR 0.95 relative to commercial insurance) (p<0.001 for each). Pertinent negatives included: age, Medicaid, and having a 90-day adverse event after the index procedure. CONCLUSIONS: Over fifteen percent of patients who required a subsequent CTR or TFR following CTR did not return to the same surgeon. Understanding what factors lead to outmigration of patients form a practice may help direct efforts for patient retention.

An analysis of fellowship training of kidney transplant surgeons in a Brazilian state.

INTRODUCTION: The lack of specialized professionals potentially contributes to the inability to meet the demand for kidney transplantations. Moreover, there is no universal proposal for the training process of transplantation surgeons. We aimed to explore the characteristics of the training program and professional activities of kidney transplantation teams in the state of Minas Gerais, Brazil. METHODS: We invited the surgeons of all 19 active kidney transplantation centers in Minas Gerais to participate in this cross-sectional study. Demographic and professional training data were compared using linear and logistic regression models. RESULTS: The response rate among the centers was high (89%); half of the surgeons answered the survey (39/78). Most of the centers were public teaching institutions, under a production-based payment contract, with a mean of 6 ± 2.4 surgeons/team; 94.2% of the centers had urologists. The surgeons were 95% male (age of 46.3 ± 9.7 years) and 59% were urologists. Most were involved in organ procurement and transplantation; only one surgeon worked exclusively with transplantation. The mean period since training was 13 ± 9.4 years, with a mean of 10 ± 9.7 years as part of the transplantation team. Only 25.6% had specialized or formal training in transplantation, with only one completing a formal medical residency for kidney transplantation. The lack of training programs was the most frequently cited reason. CONCLUSION: Kidney transplantation surgeons are not exclusive and most have not completed a formal fellowship program in transplantation because they are not available. These data indicate the need to improve training programs and facilitate the formation of new kidney transplantation teams.

Modified robotic simple prostatectomy technique: a retrospective analysis of a series of 162 surgeries performed by a high-volume surgeon.

Benign prostatic hyperplasia (BPH) affects up to 80% of men by age 80, with large-gland BPH often treated by simple prostatectomy (SP). This technique significantly improves symptoms but is associated with high rates of complications such as transfusions and infections. Minimally invasive techniques, including robotic-assisted laparoscopic simple suprapubic prostatectomy (RALSP), have emerged as alternatives. This study reports on 162 patients who underwent RALSP from May 2018 to June 2023. The mean age of the patients was 69 years, mean prostate volume 144.8 cm3, mean robot time 78.7 min, and mean blood loss 183.1 mL. Results demonstrated significant improvements in the results: prostate volume (mean decrease from 144.8 to 26.6 cm3), mean PSA level decreased from 7.8 to 0.8 (p < 0.0001), mean IPSS decreased from 23.0 to 4.4 (p < 0.0001), and mean uroflowmetry increased from 6.3 to 22.6 ml/s (p < 0.0001). No patient experienced worsening erectile function after surgery. All patients showed absence of stress urinary incontinence within 3 months. Catheterization time decreased from 4.2 to 2.6 days over the study period. The postoperative complication rate was 2.29%, with no need for surgical reintervention for complications. While RALSP showed promising results, further prospective studies are needed to compare it with other techniques. This study highlights RALSP as a viable minimally invasive option for treating large-volume BPH, offering reduced recovery times and fewer complications.

Influence of a surgeon's exposure to operating room turnover delays on patient outcomes.

BACKGROUND: A surgeon's daily performance may be affected by operating room organizational factors, potentially impacting patient outcomes. The aim of this study was to investigate the link between a surgeon's exposure to delays in starting scheduled operations and patient outcomes. METHODS: A prospective observational study was conducted from 1 November 2020 to 31 December 2021, across 14 surgical departments in four university hospitals, covering various surgical disciplines. All elective surgeries by 45 attending surgeons were analysed, assessing delays in starting operations and inter-procedural wait times exceeding 1 or 2 h. The primary outcome was major adverse events within 30 days post-surgery. Mixed-effect logistic regression accounted for operation clustering within surgeons, estimating adjusted relative risks and outcome rate differences using marginal standardization. RESULTS: Among 8844 elective operations, 4.0% started more than 1 h late, associated with an increased rate of adverse events (21.6% versus 14.4%, P = 0.039). Waiting time surpassing 1 h between procedures occurred in 71.4% of operations and was also associated with a higher frequency of adverse events (13.9% versus 5.3%, P < 0.001). After adjustment, delayed operations were associated with an elevated risk of major adverse events (adjusted relative risk 1.37 (95% c.i. 1.06 to 1.85)). The standardized rate of major adverse events was 12.1%, compared with 8.9% (absolute difference of 3.3% (95% c.i. 0.6% to 5.6%)), when a surgeon experienced a delay in operating room scheduling or waiting time between two procedures exceeding 1 h, as opposed to not experiencing such delays. CONCLUSION: A surgeon's exposure to delay before starting elective procedures was associated with an increased occurrence of major adverse events. Optimizing operating room turnover to prevent delayed operations and waiting time is critical for patient safety.

Impact of Patient- and Surgeon-Related Factors on Weight Loss after Laparoscopic Sleeve Gastrectomy-A Single-Center Study.

Background and Objectives: Surgical treatment for obesity is becoming increasingly popular. Surgeons have been trying to find a simple way to predict the type of surgical intervention that is best for a specific patient. This study aimed to determine the patient- and surgeon-related factors that affect weight loss after laparoscopic sleeve gastrectomy (LSG). Materials and Methods: A total of 129 patients underwent LSG in one surgical department. The following factors were analyzed: gender; age; highest preoperative and 6-month postoperative weight; the occurrence of obesity-related diseases, such as type 2 diabetes and hypertension; the number of surgeons involved in the surgery; and who performed the surgery, a resident or specialist. The outcomes also included length of hospital stay, operative time and complications. Statistical significance was defined as p ≤ 0.05. Results: A total of 129 patients (94 female) with a median age of 43 years and BMI of 43.1 kg/m2 underwent LSG, while a total of 109 (84.5%) patients achieved ≥50% of excess BMI loss (%EBMIL). Preoperative weight loss had no impact on %EBMIL (p = 0.95), operative time (p = 0.31) and length of hospital stay (p = 0.2). Two versus three surgeons in the operating team had no impact on surgery time (p = 0.1), length of stay (p = 0.98) and %EBMIL (p = 0.14). The operative time and length of hospital stay were similar for specialists and surgeons in training. %EBMIL was higher in the residents' surgery without statistical significance (p = 0.19). Complications occurred in 3.9% without mortality or leaks. Conclusions: Preoperative comorbidities, surgeons' experience and the number of surgeons in the operating team do not impact the complication rate, length of hospital stay, operative time and postoperative weight loss after LSG.

Gender Disparities in Surgical Subspecialties: A CMS Data Analysis.

INTRODUCTION: The persistent under-representation of women in surgery remains a critical concern within the medical profession, prompting a need for a nuanced analysis of gender distribution. Despite advancements in medical education, historical gender disparities in surgery persist, necessitating an exploration of the specific realms where gaps are most pronounced. Leveraging the 2023 Center for Medicare & Medicaid Services National Downloadable Database, this study aims to contribute insights into the multifaceted dynamics of gender representation within surgical disciplines. METHODS: Data from 1,168,064 physicians in the 2023 Center for Medicare & Medicaid Services National Downloadable Database were analyzed to distinguish between surgeons and physicians in medicine subspecialties. Univariable and multivariable logistic regression explored demographic variables, practice settings, and temporal trends to comprehensively understand factors contributing to the observed gender gap. RESULTS: The analysis revealed a statistically significant gender difference, with only 16.7% of surgeons identified as female. Temporal trends indicated a slow increase in female surgeon representation, and specialty-specific analysis unveiled variations, such as lower likelihoods of females in cardiac surgery and higher likelihoods in colorectal surgery. Multivariable logistic regression emphasized factors influencing the odds of physicians practicing surgery, with female physicians exhibiting a lower likelihood. Regional and graduation year variations also played roles in surgical practice. CONCLUSIONS: This study provides evidence-based insights into the persistent gender gap within surgical specialties, emphasizing the need for targeted interventions to enhance inclusivity and equity in the surgical workforce. The findings highlight intricate interplays of demographic, temporal, and specialty-specific factors, laying a foundation for future initiatives promoting a more diverse and inclusive surgical environment.

National Institutes of Health Funding Among Society of Asian Academic Surgery Members.

INTRODUCTION: External funding is fundamental to surgeon-scientists and many Society of Asian Academic Surgeons (SAAS) members have received funding through National Institutes of Health (NIH) grants. The amount of funding through NIH awards amongst SAAS members has yet to be evaluated. Our objective was to quantify the amount and type of NIH funding among SAAS members. METHODS: A list of all active SAAS members was compiled. The NIH Research Portfolio Online Reporting Tool's Expenditure and Results was queried to identify NIH funding among active members. RESULTS: Among 585 active SAAS members, 165 (28%) received NIH funding during their career. Of these, 110 members (66.6%) were male and 55 members (33.3%) were female. A total of 420 NIH grants have been awarded totaling $518.7 million in funding. There are currently 47 active grants totaling $34.1 million in funding. When analyzing by type, there were 226 R research grants, 63 K career development awards, 53 T and F research training and fellowships awards, and 78 other awards. Of the 63 members who received a K award, 35 members (55%) have subsequently received an R award. CONCLUSIONS: SAAS members are highly funded with 28% of members having received NIH funding totaling $518.7 million. SAAS' mission is to foster the personal and professional development of academic surgeons and we found that many SAAS members have the experience to mentor other surgeon-scientists through the process of obtaining NIH funding. Participation in organizations like SAAS can help nurture the success of future generations of surgeon-scientists.

Physician practices in referring rheumatoid hand and thumb carpometacarpal arthritis cases to hand surgeons.

OBJECTIVES: To investigate the referral practices across different medical specialties and identify possible barriers to hand surgery referral. Rheumatoid hand deformities (RHDs) and thumb carpometacarpal (CMC) arthritis may require surgery once deformities occur. However, in Saudi Arabia, the rate of referrals to hand surgeons remains low. METHODS: This was a cross-sectional study that included 102 consultants of family medicine, rheumatology, and orthopedics across various regions of Saudi Arabia. A total of 30 institutions were contacted and requested to distribute a survey questionnaire to their physicians; these institutions included 8 private hospitals, 16 government hospitals, and 6 primary healthcare centers. The survey included questions on the incidence, rate, management, knowledge, and referral of patients with RHD and CMC arthritis using a 5-point Likert scale. The Kruskal-Wallis H test was utilized in our analysis to evaluate the differences in responses among the 3 specialties. RESULTS: For RHD and thumb CMC arthritis, the referral rate was higher among orthopedic surgeons compared to rheumatologists and family medicine physicians. The main barriers to referral were patient refusal, medical treatment alone being deemed adequate, and a lack of awareness of surgical options for management. CONCLUSION: Our findings highlight discrepancies in patterns of physician referral of RHD and thumb CMC arthritis cases to hand surgeons, indicating the need for targeted interventions to improve referral rates and enhance patient outcomes.

Association of surgeon volume with complications following direct anterior approach (DAA) total hip arthroplasty: a population-based study.

BACKGROUND AND PURPOSE:  Total hip arthroplasty (THA) can be performed through various surgical approaches, including direct anterior (DAA). DAA-THA may offer faster recovery but carries a higher risk of complications, which may be mitigated by surgeon volume and experience. We examined the association of surgeons' annual surgical volume with major complications after DAA-THA in a population-based sample. METHODS:  A population-based retrospective cohort study was carried out on primary DAA-THA patients in Ontario between April 2016 and March 2021. We used restricted cubic splines to visually define the association between annual DAA surgeon volume and the risk of major surgical complications (fractures, dislocations, infections, and revisions) within 1 year of surgery. We further compared the complication rates amongst different DAA volume categories (< 30, 30-60, and > 60 cases/year). RESULTS: The study encompassed 9,672 DAA-THA patients (52% female, median age 67 years). We showed a sharp decline in the probability of complications as the surgical volume of DAA-THA increased within the lower range of 0-30 cases/year; the probability slightly increased after the surgical volume exceeded 60 cases/year. The overall complication rates were 3.09%, 2.24%, and 2.18% for the surgical experience group of < 30 cases/year, 30-60 cases/year, and > 60 cases/year, respectively. CONCLUSION:  There was an inverse relationship between surgical volume and complication rates in DAA-THA within the lower volume ranges. Maintaining a surgical volume of at least 30 DAA-THA cases/year can minimize complications, emphasizing the importance of surgical volume in this approach.

Surgeon Perceptions and Variations in Surgical Morbidity and Mortality Conference: Report of a Survey from the American College of Surgeons Board of Governors.

OBJECTIVE: To highlight the evolution of surgical morbidity and mortality conferences (MMCs) from the early 20th century as a means of identifying surgeon error into current practices as identifying hospital-based system factors that contribute to adverse patient events. Further, to elucidate differences in the perception of MMCs between trainees and attending surgeons as well as differences in the structure of MMCs geographically and by institution type. DESIGN: We developed a survey that was distributed to current American College of Surgeon members through Survey Monkey. SETTING: Survey-based study. PARTICIPANTS: Current members of the American College of Surgeons, including Board of Governors, surgeons, and trainees. RESULTS: There were a total of 1,396 responses to the survey, 814 (58%) from surgical trainees and 582 (42%) from attending surgeons. Both surgical trainees and attending surgeons noted that the most common day for MMCs was Wednesday and that the most common time for MMCs was before 7:30 AM. Further, most surgical trainees and attending surgeons noted that there was no structured format to their institution's MMCs and that increased attending surgeon engagement would make MMCs more educational. Significant variations in MMCs existed across both geographic region and by institution type. CONCLUSION: The results from this survey highlight key aspects of MMCs that contribute to their educational value. Staff engagement was noted to be the most educational aspect of MMCs. While geographic and institutional differences will likely persist, efforts should be made to increase staff engagement at MMCs in addition to a more structured approach.

A calculator for musculoskeletal injuries prediction in surgeons: a machine learning approach.

BACKGROUND: Surgical specialists experience significant musculoskeletal strain as a consequence of their profession, a domain within the healthcare system often recognized for the pronounced impact of such issues. The aim of this study is to calculate the risk of presenting musculoskeletal injuries in surgeons after surgical practice. METHODS: Cross-sectional study carried out using an online form (12/2021-03/2022) aimed at members of the Spanish Association of Surgeons. Demographic variables on physical and professional activity were recorded, as well as musculoskeletal pain (MSP) associated with surgical activity. Univariate and multivariate analysis were conducted to identify risk factors associated with the development of MSP based on personalized surgical activity. To achieve this, a risk algorithm was computed and an online machine learning calculator was created to predict them. Physiotherapeutic recommendations were generated to address and alleviate each MSP. RESULTS: A total of 651 surgeons (112 trainees, 539 specialists). 90.6% reported MSP related to surgical practice, 60% needed any therapeutic measure and 11.7% required a medical leave. In the long term, MSP was most common in the cervical and lumbar regions (52.4, 58.5%, respectively). Statistically significant risk factors (OR CI 95%) were for trunk pain, long interventions without breaks (3.02, 1.65-5.54). Obesity, indicated by BMI, to lumbar pain (4.36, 1.84-12.1), while an inappropriate laparoscopic screen location was associated with cervical and trunk pain (1.95, 1.28-2.98 and 2.16, 1.37-3.44, respectively). A predictive model and an online calculator were developed to assess MSP risk. Furthermore, a need for enhanced ergonomics training was identified by 89.6% of surgeons. CONCLUSIONS: The prevalence of MSP among surgeons is a prevalent but often overlooked health concern. Implementing a risk calculator could enable tailored prevention strategies, addressing modifiable factors like ergonomics.

Effect of surgeon-patient sex discordance on ventral hernia repair outcomes.

PURPOSE: Concordance is an important dimension of the physician-patient relationship that may be linked to health care disparities. The purpose of this study was to determine if sex discordance between surgeon and patient impacts surgical outcomes. METHODS: A retrospective review of prospectively collected data obtained from the Abdominal Core Health Quality Collaborative (ACHQC) registry was performed on all patients who underwent ventral hernia repair. Surgical site occurrences (SSO), surgical site infections (SSI), surgical site occurrence requiring procedural intervention (SSOPI) and 30-day readmission rates were recorded. RESULTS: Female patients operated on by male surgeons have increased odds of having an SSI/SSO (OR 1.099, 95% CI 1.022-1.181), SSOPI (OR 1.156, 95% CI 1.031-1.297), and readmission (OR 1.259, 95% CI 1.128-1.406) when compared to male patients operated on by male surgeons. There was no significant difference in adverse outcomes between patient groups when operated on by female surgeons. CONCLUSION: Sex discordance between surgeon and patient is associated with increased odds adverse outcomes when male surgeons operate on female patients.

Association of Acute Care Surgeon Involvement With Post-Surgery Complications.

INTRODUCTION: Acute care surgeons are experts in trauma treatment, emergency surgery, and critical surgical care. Here, we analyzed the association of acute care surgeons on postoperative outcomes of emergency general surgery. METHODS: This retrospective study included 92 patients who underwent emergency general surgery at our institution between January 2020 and September 2021. Propensity score matching was used to analyze postoperative outcomes. The primary outcome was postoperative complications, while secondary outcomes included perioperative management and surgery-related and postoperative complications. Logistic regression analysis was used to estimate the odds ratios for all complications. In this study, acute care surgeons were defined as acute care surgery (ACS)-certified surgeons by the Japanese Society for Acute Care Surgery. RESULTS: Overall, 30 patients were treated by an acute care surgeon and general surgeons (ACS group), and 62 patients were treated by general surgeons (non-ACS group), respectively. Propensity score matching identified 30 patients with balanced baseline covariates, in each group. The ACS group had lower complication rates (Clavien-Dindo classification ≥2) than the non-ACS group (17% versus 40%, P = 0.08). The ACS group had a significantly shorter surgery duration than the non-ACS group (75 min versus 96 min, P = 0.014). In the logistic analysis, acute care surgeon involvement was identified as an independent predictor for the decrease in all complications (odds ratio, 0.15; 95% confidence interval, 0.02-0.64). CONCLUSIONS: It was suggested that the involvement of acute care surgeons may reduce the overall complication rate in emergency general surgery.

Does practice make perfect? Studying the relationship between surgeon experience and patient outcomes for paraesophageal hernia repairs.

BACKGROUND: It has been reported that higher surgeon experience leads to better patient outcomes. In this study, we look at surgeon experience and its association with postoperative outcomes and variation among the practice of surgeons performing paraesophageal hernia repairs (PEH). METHOD: This was a retrospective study of 1155 patients who underwent PEH repair at a single institution (2010-2023). Surgeon experience was defined as the number of surgeries performed per surgeon and was split using the median surgeries (n = 100), with surgeons performing at or above the median categorized as high-experience and below the median as low-experience surgeons. A multivariable logistic regression model was used to test correlation between surgeon experience and variables, including demographics and intra- and post-operative outcomes. RESULTS: High-experience surgeons performed more elective cases (93.4% vs 85.5%), but low-experience surgeons operated more on emergent (2.7% vs 0.9%), semi-elective (2.3% vs 1.4%), and urgent cases (9.5% vs 4.3%). Low-experience surgeons operated more on patients who were older (67.5 vs 63.2 years, p < 0.001) and had an increased risk of CVD (72.9% vs 61.5%, p < 0.001). Intraoperative OR time was considerably less for high-experience surgeons (115.8 vs 172.9 min, p < 0.001). Low-experience surgeons had increased risk of intra-operative complications (4.5% vs 1.8%, p = 0.021) and post-op pneumonia within 30 days (1.8% vs 0.3%). However, long-term outcomes such as hernia recurrence (OR: 1.10, CI: 0.78-1.54) and redo-operations for hiatal hernia (OR: 1.10, CI: 0.65-1.75) were similar for both groups. CONCLUSION: High-experience surgeons perform more complex revisional surgeries in less time with fewer complications. Low-experience surgeons operated more on patients with higher comorbidities but had significantly higher OR times. Long-term results of recurrence and redo-operations were comparable. These variations suggest that high-experience surgeons are more efficient while operating on more complex cases. These findings have pivotal implications to facilitate mentorship and education among less-experienced surgeons.

Is surgeon annual case volume related with intra and postoperative complications after ventral hernia repair? Uni- and multivariate analysis of prospective registry-based data.

BACKGROUND: Literature on a potential relationship between surgeon case volume and intra- or postoperative complications after ventral hernia repair remains scarce. METHODS: Patients who underwent ventral hernia repair between 2011 and 2023 were selected from the prospectively maintained French Hernia-Club Registry. Outcome variables were: intraoperative events, postoperative general complications, surgical site occurrences, surgical site infections, length of intensive care unit (ICU), and patient-reported scar bulging during follow-up. Surgeons' annual case volume was categorized as 1-5, 6-50, 51-100, 101-125, and > 125 cases, and its association with outcome volume was evaluated using uni- and multivariable analyses. RESULTS: Over the study period, 199 titular or temporary members registered 15,332 ventral hernia repairs, including 7869 primary, 6173 incisional, and 212 parastomal hernia repairs. In univariate analysis, surgeons' annual case volume was significantly related with all the postoperative studied outcomes. After multivariate regression analysis, annual case volume remained significantly associated with intra-operative complications, postoperative general complications and length of ICU stay. A primary repair was independently associated with fewer intra- and post-operative complications. CONCLUSION: In the present multivariable analysis of a large registry on ventral hernia repairs, higher surgeon annual case volume was significantly related with fewer postoperative general complications and a shorter length of stay, but not with fewer surgical site occurrences, nor with less patient-reported scar bulging. Factors in the surgeons' case mix such as the type of hernia have significant impact on complication rates.

Antibiotic Prophylaxis in Breast Cancer Surgery: A Multicontinental Survey Study.

INTRODUCTION: Prophylactic antibiotic (PPA) usage is a common practice in breast cancer surgery. However, there is limited information on the global patterns of antibiotic usage in this setting. This study aimed to investigate the prevalence and preferences of PPA usage in breast cancer surgery among surgeons across different continents. METHODS: A multicontinental survey study was conducted among 295 surgeons who were actively involved in breast cancer surgery around the world. The survey collected information on PPA usage, preferred antibiotic choice, and factors influencing antibiotic prescribing patterns. RESULTS: The survey revealed that PPA usage was widespread, with an overall prevalence of 89% among respondents. Cephalosporins were the most preferred antibiotics for prophylaxis. Antibiotic usage was similar and high among surgeons practicing in Europe (90%), in Asia (87%), and in other continents (91%). Academic surgeons and those dedicating a larger portion of their practice to breast cancer surgery reported a more frequent use of PPAs. Surgeons with >25 y of practice had the lowest rate of PPA use. CONCLUSIONS: This multicontinental survey study highlights the high prevalence of PPA usage in breast cancer surgery among surgeons around the world, with cephalosporins being the preferred choice. Furthermore, academic surgeons and those specializing in breast cancer surgery were more likely to prescribe PPAs. These findings provide valuable insights into the current practices and trends in antibiotic usage in breast cancer surgery, emphasizing the need for further research and guidelines to optimize antibiotic stewardship in this surgical setting.
