Comparison of Appendectomy Outcomes Between Senior General Surgeons and General Surgery Residents

Seniority of Surgeon in Chronic Subdural Hematoma Recurrence: A Systematic Review and Meta-analysis

Chronic subdural hematoma (CSDH) is increasingly common, particularly in the older and multimorbid population. Surgical proficiency in management is required in the early years of U.K. neurosurgical training with most cases performed by nonconsultant-grade surgeons. The aim of this systematic review was to examine the effect of surgeon seniority on recurrence for patients with CSDH. Full-text articles comparing surgical treatment for CSDH with a "senior" (consultant/attending level) or "junior" (resident/registrar or similar) lead surgeon were identified. MEDLine and EMBASE databases were searched. The primary outcome of this study was recurrence. Secondary outcomes included postoperative complications and mortality rate. A random effects meta-analysis was performed. The risk of bias was assessed using the National Institute of Health risk of bias toolkit. Five studies were included in the final analysis (n = 941 total patients). Individually, no study identified a significant difference in recurrence rate and postoperative complications between senior and junior neurosurgeons. On meta-analysis, junior-led evacuations had lower recurrence rates on pooled univariable analysis (12.0% vs. 17.9% [odds ratio 0.48, 95% confidence interval 0.29-0.78, I2 = 0%]) (3 studies). Seniority of surgeon was not associated with increased rates of recurrence patients undergoing CSDH surgery. Complexity of operation may be a confounding factor in observed lower recurrence rates with more junior operators.

Postoperative Complications Following Appendectomy: A Single-Center Retrospective Study

Background Appendicitis is a common surgical emergency with a global incidence rate of approximately 8%, necessitating prompt intervention to prevent complications. Appendectomy, either through open surgery or laparoscopy, is the standard treatment. Understanding the factors contributing to post-appendectomy complications is crucial for improving patient outcomes. Aim This retrospective study aimed to assess the surgical outcomes of various surgical approaches for appendicitis in Taif City, Saudi Arabia, specifically at King Abdulaziz Specialist Hospital. Methodology A total of 220 patients who underwent appendectomy in 2022 were included in the study. Data were obtained from medical files, and statistical analysis was performed using IBM SPSS Statistics for Windows, Version 26.0 (Released 2019; IBM Corp., Armonk, NY, USA). chi-square and Fisher's exact tests were utilized, with a significance level set at p < 0.05. Results The majority of patients fell within the 20-39 age group (n = 124, 56.4%), and males constituted 63% (n = 140) of the cohort. Mean complications post-surgery were observed in 5.5% (n = 12) of cases, with surgical site infection being the most common complication (n = 9, 75%). Patients with complicated appendicitis had a significantly higher rate of surgical complications (n = 8, 44.4%) compared to those without complicated appendicitis (n = 4, 2%, p = 0.000). Longer hospital stays were associated with a higher incidence of complications (p = 0.008). The American Society of Anesthesiologists classification showed a significant association with complications (p = 0.000). Conclusions Our study underscores the importance of early diagnosis, appropriate surgical management, and infection prevention strategies in reducing post-appendectomy complications. Factors such as complicated appendicitis, longer hospital stays, and higher ASA classification were associated with increased complication rates.

Operating room organization and surgical performance: a systematic review

BACKGROUND

Organizational factors may influence surgical outcomes, regardless of extensively studied factors such as patient preoperative risk and surgical complexity. This study was designed to explore how operating room organization determines surgical performance and to identify gaps in the literature that necessitate further investigation.

METHODS

We conducted a systematic review according to PRISMA guidelines to identify original studies in Pubmed and Scopus from January 1, 2000 to December 31, 2019. Studies evaluating the association between five determinants (team composition, stability, teamwork, work scheduling, disturbing elements) and three outcomes (operative time, patient safety, costs) were included. Methodology was assessed based on criteria such as multicentric investigation, accurate population description, and study design.

RESULTS

Out of 2625 studies, 76 met inclusion criteria. Of these, 34 (44.7%) investigated surgical team composition, 15 (19.7%) team stability, 11 (14.5%) teamwork, 9 (11.8%) scheduling, and 7 (9.2%) examined the occurrence of disturbing elements in the operating room. The participation of surgical residents appeared to impact patient outcomes. Employing specialized and stable teams in dedicated operating rooms showed improvements in outcomes. Optimization of teamwork reduced operative time, while poor teamwork increased morbidity and costs. Disturbances and communication failures in the operating room negatively affected operative time and surgical safety.

CONCLUSION

While limited, existing scientific evidence suggests that operating room staffing and environment significantly influences patient outcomes. Prioritizing further research on these organizational drivers is key to enhancing surgical performance.

Challenges and Solutions in Postoperative Complications: A Narrative Review in General Surgery

In general surgery, the goal of achieving favorable results following surgical procedures is consistently impeded by the intricate range of postoperative problems. This abstract summarizes a comprehensive narrative study that examines the numerous difficulties associated with postoperative complications and investigates potential remedies. With the progress of surgical practices, the intricacies of complications also increase, requiring a flexible comprehension of the diverse scenarios. This review examines the many factors contributing to postoperative complications, including patient-specific variables and advancing surgical procedures. It also explores the broader consequences of these problems on individual patients and healthcare systems. The economic results, such as extended hospitalizations and increased allocation of resources, highlight the need for specific solutions. This abstract also emphasizes the review's examination of novel methodologies, technology incorporations, and cooperative tactics as potential transformative factors. This abstract provides an overview of the ongoing efforts to change how postoperative complications are understood in general surgery. It highlights the importance of taking preventive measures and adopting a comprehensive approach to patient care.

New Gaps and Urgent Needs in Graduate Medical Education and Training in Abortion

Abortion is essential health care, and abortion training and education are essential at all levels of medical education. Among the most common procedures performed in obstetrics and gynecology (OB/GYN), abortion is a core competency for OB/GYN residency programs. For nearly 50 years, the procedure was federally protected by the U.S. Supreme Court's January 22, 1973, Roe v Wade decision. On June 24, 2022, amidst increasing state restrictions limiting abortion access, the Court's decision on Dobbs v Jackson Women's Health Organization effectively reversed Roe . As a result, immediate bans on abortion went into effect across the country, removing access to abortion for millions of people and newly limiting training and education in this core competency for many medical residents. As of June 2022, nearly half of U.S. OB/GYN residency programs and more than 40% of residents are located in states that have banned or are likely to ban abortion. In states where abortion is restricted or illegal, states must adapt quickly to ensure their residents meet training requirements. This adaptation may include developing and leveraging relationships with programs in states where access is protected, depending on simulation, and placing greater emphasis on education and training in pregnancy loss management and postabortion care. None of these is a comprehensive solution and even all together, they are insufficient to train residents and medical students. Ultimately, many future physicians will not receive the training they need to provide full reproductive health care to their pregnant patients. Legal and other systems of support are needed to ensure that current and future physicians can provide compassionate, evidence-based reproductive health care, including essential abortion care.

Declining Surgical Resident Operative Autonomy in Acute Care Surgical Cases

INTRODUCTION

Surgical resident operative autonomy has decreased markedly over time, reducing resident readiness for independent practice. We sought to examine operative resident autonomy for emergency acute care surgery (ACS) compared to elective cases and associated patient outcomes at veterans affairs hospitals.

METHODS

The Veterans Affairs Surgical Quality Improvement Program database was queried for ACS cases (emergency general, vascular, and thoracic) at veterans affairs hospitals from 2004 to 2019. Cases are coded prospectively for the level of supervision: attending primary surgeon (AP); attending scrubbed with resident surgeon (AR); resident primary (RP), attending not scrubbed. Baseline demographics, operative variables, and outcomes were compared.

RESULTS

A total of 61,275 ACS cases and 605,146 elective cases were performed during the study period. The ACS had a higher proportion of RP cases (7.2% versus 5.7%, P < 0.001). The proportion of ACS RP cases decreased from 9.9% to 4.1% (58.6%); elective RP cases decreased from 8.9% to 2.9% (67.4%). The most common ACS RP surgeries were appendectomy, amputations, and cholecystectomy. RP cases had lower American Society of Anesthesia class and lower median work relative value units than AP and AR. There was no difference between mortality rates of RP compared to AP (adjusted odds ratio [OR] 0.94 [0.80-1.09] or AR 0.94 [0.81-1.08]). While there was no difference in complications between the RP and AP (OR 1.01 [0.92-1.12]), there were significantly more complications in AR compared to RP (OR 1.20 [1.10-1.31]).

CONCLUSIONS

More autonomy is granted for ACS cases compared to elective cases. While both decreased over time, the decrease is less for ACS cases. Resident autonomy does not negatively impact outcomes, even in emergent cases.

Methods of assessment of the level of surgeons for minimally invasive fixation of distal radius fractures: "expertise" versus "performance"

INTRODUCTION

The results of surgical techniques vary depending on the level of the surgeon's experience. The level of expertise can be evaluated quantitatively or qualitatively. In this study, we evaluated the duration of the procedure and the size of the incision of minimally invasive fixation of distal radius fractures as a means of grading expertise and surgical performance. The null hypothesis of our study was that the level of expertise did not match the level of performance.

MATERIAL AND METHODS

The study included 52 surgeons split in five levels of expertise who had performed 467 minimally invasive fixations of distal radius fractures. The performance of the surgeons in terms of duration of the procedure and size of the incision were scored according to the five levels of surgical experience using four different methodologies: clinical (setting limits compared to data found in literature), statistical (setting statistical limits of comparison in percentiles (20th, 40th, 60th, 80th) for each of the two parameters measured), arithmetical (setting limits compared to equal intervals for each of the 2 variables), and success rate (setting a threshold for each of the 2 variables).

RESULTS

Our results showed a great disparity between levels of experience depending on the method used. The scores for levels 1 and 2 were 72% for expertise, 13% for performance according to the clinical method, 75% for the statistical method, 0% for the arithmetical method, and 57% according the success rate. The rate of level 3 was 23% for expertise, 41% for performance by the clinical method, 17% by the statistical method, 17% by the arithmetical method, and 15% by the success rate. The rates of levels 4 and 5 were 5% for expertise, 46% for performance clinical method, 8% by the statistical method, 83% by the arithmetical method, and 28% by the success rate.

DISCUSSION

The null hypothesis of our study was confirmed by the results which show that there was no correlation between levels of expertise and performance. The clinical method of assessment appears to reflect best the true level of performance of the surgeon.

CONCLUSION

Publications reporting the results of a surgical technique for a given pathology should always mention the level of performance as measured on a clinical scale.

Systematic review and meta-analysis comparing perioperative outcomes of emergency appendectomy performed by trainee vs trained surgeon

BACKGROUND

Appendectomy is a benchmark operation for trainee progression, but this should be weighed against patient safety and perioperative outcomes.

METHODS

Systematic literature review and meta-analysis comparing outcomes of appendectomy performed by trainees versus trained surgeons.

RESULTS

Of 2086 articles screened, 29 studies reporting on 135,358 participants were analyzed. There was no difference in mortality (Odds ratio [OR] 1.08, P = 0.830), overall complications (OR 0.93, P = 0.51), or major complications (OR 0.56, P = 0.16). There was no difference in conversion from laparoscopic to open surgery (OR 0.81, P = 0.12) and in intraoperative blood loss (Mean Difference [MD] 5.58 mL, P = 0.25). Trainees had longer operating time (MD 7.61 min, P < 0.0001). Appendectomy by trainees resulted in shorter duration of hospital stay (MD 0.16 days, P = 0.005) and decreased reoperation rate (OR 0.78, P = 0.05).

CONCLUSIONS

Appendectomy performed by trainees does not compromise patient safety. Due to statistical heterogeneity, further randomized controlled trials, with standardized reported outcomes, are required.

Operative Time Is Independently Associated With Morbidity in Pediatric Complicated Appendicitis

INTRODUCTION

Complicated appendicitis is a common cause of morbidity in children. Studies have analyzed the risk factors in the surgical treatment of this pathology, including obesity and disease severity, but not operative time (OT). We hypothesize that OT is independently associated with increased morbidity for children with complicated appendicitis.

METHODS

Data were extracted from the 2018 and 2019 National Surgical Quality Improvement Program-Pediatrics data sets. Patients aged 2-18 y who underwent laparoscopic appendectomy for complicated appendicitis were identified. Patient demographics, disease severity, and operative details were evaluated. Surgical site infections (SSIs), hospital length of stay (LOS), ≤30-d readmissions and reoperations, interventional radiologic drain (IR-drain) placement, pneumonia, and death were analyzed. Logistic and linear regression analyses were performed.

RESULTS

A total of 8168 patients were analyzed, with a mean age of 9.96 ± 3.9 y and a mean weight of 41.2 ± 21.2 kg. The mean OT was 55.8 ± 24.9 min, with a mean LOS of 5.15 ± 3.37 d. For every 1-min increase in OT, there was an independently associated increase in the likelihood of any SSI (odds ratio [OR] = 1.01; 95% confidence interval [CI] 1.008-1.013), superficial SSI (OR = 1.01; 95% CI 1.004-1.020), organ-space SSI (OR = 1.01; 95% CI 1.008-1.013), IR-drain placement (OR = 1.01; 95% CI 1.008-1.013), and readmission (OR = 1.004; 95% CI 1.000-1.007).

CONCLUSIONS

Prolonged OT is independently associated with greater likelihood of any SSI, superficial SSI, organ-space SSI, IR-drain placement, readmission and reoperation within 30 d, and longer hospital LOS. There is a need to determine modifiable factors that prolong OT to aid in the optimization of routine operations to reduce patient morbidity.

Chief Resident Indirect Supervision in Training Safety Study: Is a Chief Resident General Surgery Service Safe for Patients?

OBJECTIVE

There has been concern expressed amongst the medical educational community regarding the readiness of general surgery residents in the United States to be competent practicing attendings upon graduation and that limited autonomy may be a contributing factor to this unpreparedness. The purpose of this study was to evaluate an RRC-accredited general surgery residency chief resident acute care surgery service with indirect supervision of cases in terms of safety and outcomes compared to traditional general surgeon cases with direct supervision. The study focused on common general surgical procedures, specifically cholecystectomies, appendectomies, and inguinal and ventral hernia repairs.

DESIGN

A retrospective review was conducted of patient data from August 2016 to June 2018 to review all patients 16 years old and older who had received one of the following procedures: appendectomy, cholecystectomy, inguinal hernia repair, or ventral hernia repair. Patient characteristics, procedure type, procedure time, estimated blood loss, complications, length of hospital stay, 30-day readmission, 30-day ED visit, need for reoperation, and mortality were compared between attending direct supervision and chief resident indirect supervision surgery services.

SETTING

A single institution associated with a community based-university associated hybrid general surgery residency was included in this study.

PARTICIPANTS

Patients aged 16 years or older who underwent one of the operations of interest and were discharged between the dates of August 2016 and June 2018. The operations were performed by, or indirectly supervised by, attendings who were both private surgeons and also covered the chief resident service.

RESULTS

A total of 1000 cases were reviewed, with a total of 960 included in the final data after exclusions applied. Of the 960 cases included, 68.4% were traditional attending surgeon cases with direct supervision and 31.6% were chief resident service cases with indirect supervision. A total of 161 appendectomies, 396 cholecystectomies, 201 inguinal hernias and 202 ventral hernias were included. Overall, patients in the chief resident service were more often minorities (27.7 vs. 9.4%, p < 0.001), female (56.4 vs. 44.6%, p = 0.001), younger (40 vs. 55 years, p < 0.001), had a higher BMI (31.2 vs. 29.6, p = 0.018), and a lower ASA class (class 1+2 was 86.4 vs. 65.6%, p < 0.001). The median Charleson Comorbidity Index of the chief resident service patients was lower than that of the attending service (0 vs. 2, p < 0.001). Chief resident service cases were also more often urgent cases (40.6 vs. 22.8%, p < 0.001). Overall, the 30-day complication rate was similar between the two services (5.6 vs. 5.8%, p = 1.000). Complications observed from chief resident service and attending service supervised cases included pneumonia (0.3 vs. 0.5%, p = 1.000), surgical site infection (2.3 vs. 1.5%, p = 0.389), UTI (1.0 vs. 0.6%, p = 0.685), acute kidney injury (0.0 vs. 0.8%, p = 0.333), small bowel obstruction (0.0 vs. 0.6%, p = 0.314), cerebrovascular accident (0.0 vs. 0.2%, p = 1.000), and hematoma/seroma (2.3 vs. 1.7%, p = 0.500). There were no statistically significant differences in procedure-specific complications between services. There was one 30-day mortality in the study population, in the attending service group.

CONCLUSIONS

This study's data suggest that a chief resident acute care surgery service with indirect supervision of cases is safe in this community with regards to appendectomies, cholecystectomies and hernia repairs.

The Resident-Run Minor Surgery Clinic: A Four-Year Analysis of Patient Outcomes, Satisfaction, and Resident Education

OBJECTIVE

A resident-run minor surgery clinic was developed to increase resident procedural autonomy. We evaluated whether 1) there was a significant difference between complications and patient satisfaction when procedures were independently performed by surgical residents vs. a surgical attending and 2) if participation was associated with an increase in resident procedural confidence.

DESIGN

Third year general surgery residents participated in a weekly procedure clinic from 2014-2018. Post-procedure complications and patient satisfaction were compared between patients operated on by residents vs. the staff surgeon. Residents were surveyed regarding their confidence in independently performing a variety of clinic-based patient care tasks.

SETTING

Massachusetts General Hospital General in Boston, MA; an academic tertiary care general surgery residency program.

PARTICIPANTS

Post-graduate year three general surgery residents that ran the clinic as part of a general surgery rotation.

RESULTS

1230 patients underwent 1592 procedures (612 in resident clinic, 980 in attending clinic). There was no significant difference in the 30-day complication rate between patients operated on by the resident vs. attending (2.5% vs. 1.9%, p = 0.49). 459 patient satisfaction surveys were administered with a 79.1% response rate. There was no significant difference in the overall quality of care rating between residents and the attending surgeon (87.5% top-box rating vs. 93.1%, p = 0.15). Twenty-one residents completed both a pre- and post-rotation survey (77.8% response rate). The proportion of residents indicating that they could independently perform a variety of patient care tasks significantly increased across the rotation (all p < 0.05).

CONCLUSION

Mid-level general surgery residents can independently perform office-based procedures without detriment to safety or patient satisfaction. The resident-run procedure clinic serves as an environment for residents to grow in confidence in both technical and non-technical skills. Given the high rate at which patients provide resident feedback, future work may investigate how to best incorporate patient derived evaluations into resident assessment.

Independent Operating by General Surgery Residents: An ACS-NSQIP Analysis

OBJECTIVE

Surgical resident autonomy during training is paramount to independent practice. We sought to determine prevalence of general surgery resident autonomy for surgeries commonly performed on emergency general surgery services and identify trends with time.

DESIGN

We queried ACS-NSQIP for patients undergoing one of 7 emergency general surgery operations. We evaluated trends in independent operating (defined as a resident operating alone, without attending having scrubbed) over the study period. Other outcomes of interest: operative time, 30-day-mortality and complications.

SETTING

The ACS-NSQIP database.

PARTICIPANTS

Patients undergoing one of 7 emergency general surgery operations.

RESULTS

Data regarding resident involvement was only available for the years 2005-2010. 90,790 operations were performed, 922 (1%) by residents operating independently. Appendectomy accounted for 61% independent cases. Independent resident operating was associated with a longer operative time (65 versus 58 minutes, p < 0.001), but lower risk of bleeding requiring transfusion (p < 0.001) and progressive renal insufficiency (p = 0.02). Independent operating was not associated with increased risk of complications/mortality.

CONCLUSION

Independent resident operating is rare, even with increasing attention to its importance, and is not associated with increased complications or mortality. National data on this subject is old and not currently collected. There is need for a national registry on resident involvement to understand the current effect of independent operating on outcomes.

Examining the Development of Operative Autonomy in Vascular Surgery Training and When Trainees and Program Directors Agree and Disagree

BACKGROUND

Lack of autonomy in the operating room (OR) during general surgery residency is a major contributing factor to low confidence operating independently after graduation. Although attempts to address decreased autonomy and development of entrustment in the OR are being made in general surgery programs, this issue has not been examined thoroughly in vascular surgery. We sought to determine barriers and opportunities for developing operative autonomy during vascular surgery training by surveying program directors (PDs) and trainees (integrated residents and fellows) in U.S. vascular surgery training programs.

METHODS

An anonymous electronic survey was sent via email to all PDs (n = 155) and trainees (n = 516) in United States vascular surgery training programs. Demographics, academic characteristics, and responses regarding factors impacting the development of entrustment were collected.

RESULTS

Thirty-five PDs and 100 trainees completed the survey (22.5% and 19.4% response rate, respectively). Sixty percent of trainees were integrated residents and 40% were fellows. Twenty percent of PDs and 33% of trainees were female, and 5% of all PDs and trainees were from underrepresented minorities. The single most positive factor affecting the development of autonomy according to trainees and PDs is familiarity of the faculty with the trainee. Both PDs and trainees thought the trainee's preparation for the case positively affected development of autonomy; however, more PDs believed that involvement with preoperative preparation in particular (marking the patient, consenting the patient, filling out a history and physical, prepping and draping the patient) was important (P < 0.05). PDs believed that duty-hour limitations negatively affected the trainee's ability to develop autonomy in the OR, whereas more trainees believed that hospital or OR efficiency policies played a negative role (P < 0.05). Finally, compared with trainees, PDs believed that the appropriate amount of time for safe struggle before the attending should take over the case was when OR efficiency was compromised or at any moment the trainee is unsure of themselves (P < 0.05); trainees believed that the attending should take over the case after the limit of their skill set or troubleshooting ability was reached (P < 0.05).

CONCLUSIONS

Familiarity of the attending physician with the trainee is an important positive factor for development of entrustment and autonomy in vascular surgery trainees. Duty-hour limitations and belief of the need for hospital efficiency may negatively impact operative independence of trainees. An open discussion about balancing OR efficiency and trainees' safe struggle is essential to address the growth of independent operative skills in vascular surgery trainees.

Appendectomy as Teaching Operation: No Compromise in Safety-An Audit of 17,106 Patients

OBJECTIVE

In a surgical career, teaching of surgical procedures plays a central role. In this study we want to evaluate the influence of teaching in appendectomies on the in-hospital outcome.

DESIGN AND SETTING

Retrospectively, 26,436 cases from the national quality measurement database (AQC) between the years 2009 and 2017 were evaluated using the diagnosis and the procedure codes. Included were all cases with appendicitis (International Classification of Diseases diagnostic codes K35-K37), surgical treatment (appendectomy), and a documented teaching status of the procedure. Variables were sought in bivariate and multivariate analyses. The occurrence of any complication was the primary outcome, whereas in-hospital mortality was the secondary outcome.

PARTICIPANTS

A total of 17,106 patients with a mean age of 37 ± 19 years remained for final analysis. A total of 6267 operations (37%), were conducted as teaching-operations. Seventy-four percent of all teaching procedures were performed by residents.

RESULTS

We found no statistical association between teaching operations and complication rates or mortality. However, the teaching group showed longer duration of surgery (+ 11%).

CONCLUSIONS

There was no influence of the training status of the appendectomy procedure on complication rates and in-hospital mortality. However, there was a prolonged duration of surgery. Despite these statistically significant differences, a comparable clinical outcome was observed in all patients, thus justifying the benefits of resident training.

Quantifying the effect of resident education on outcomes in pediatric appendicitis

BACKGROUND/PURPOSE

Surgical residents are involved in the care of patients in a climate where quality of care is an important outcome measure. The purpose of this study was to evaluate the effect of resident involvement on appendectomy outcomes.

METHODS

We retrospectively reviewed appendectomies, ages 0-18, from January 2016 to December 2018. Operative time, operative charges, and postoperative outcomes were evaluated for cases with and without a resident. Data were analyzed using Wilcoxon rank and Fisher's exact tests.

RESULTS

Of 1842 appendectomies (1267 resident present and 575 no resident present), there was no difference in postoperative stay, abscess formation, readmission, or emergency room visits for simple or complex appendicitis. Operative time was significantly longer for cases of simple appendicitis by 10 min (p = <0.0001) and charges significantly higher by $600 (p = <0.0001) when a resident was involved in the case. These differences held true for complex appendicitis (time longer by 9 min, p = <0.0001 and charges higher by $500, p = 0.03).

CONCLUSION

Resident involvement results in an increase in operative time and charges, with no difference in length of stay or complications. These results highlight the cost of resident involvement, without an increase in complications experienced by patients.

LEVEL OF EVIDENCE

Level III evidence.

Impact of Trainee Involvement on Video-Assisted Thoracoscopic Lobectomy for Cancer

BACKGROUND

Previous literature in other surgical disciplines regarding the impact of resident and fellow involvement on operative time and outcomes has yielded mixed results. The impact of trainee involvement on minimally invasive thoracic surgery is unknown. This study compared risk-adjusted differences in operative time and outcomes of video-assisted thoracoscopic lobectomy for cancer between cases performed with and without residents and fellows involved.

METHODS

All patients undergoing elective video-assisted thoracoscopic lobectomy for cancer between 2008 and 2018 were identified in the Veterans Affairs Surgical Quality Improvement Program database. Patients were stratified into 2 cohorts: cases with residents and fellows involved, and cases performed only by attending surgeons. Primary outcomes included operative time, postoperative hospital length of stay, and composite 30-day morbidity and mortality. Secondary outcomes included factors associated with high and low trainee operative autonomy.

RESULTS

A total of 3678 patients met study inclusion criteria. In all, 1780 cases were performed with residents and fellows involved (median postgraduate year, 5; interquartile range, 4-7). Multivariate analysis showed that operative time was significantly shorter in resident- and fellow-involved cases compared with attending-only cases (mean [SD], 3.6 [1.4] versus 3.8 [1.6] hours; P < .001). There were no significant differences in composite 30-day morbidity and mortality (16.0% versus 17.1%; adjusted odds ratio = 0.93; 95% confidence interval, 0.77-1.11; P = .40) or length of stay. Substratification of trainees by postgraduate year resulted in similar findings. Cases performed in July through October and those in the Northeastern United States were associated with low autonomy.

CONCLUSIONS

Current training paradigms in thoracic surgery are safe, and the involvement of motivated and skilled trainees with appropriate supervision may benefit operative duration.

Laparoscopic appendectomy as an index procedure for surgical trainees: clinical outcomes and learning curve

Surgical training is essential to maintain safety standards in healthcare. The aim of this study is to evaluate learning curves and short-term postoperative outcomes of laparoscopic appendectomy (LA) performed by trainees (TRN) and attendings (ATT). The present study included the medical records of patients with acute appendicitis who underwent a fully LA in our department between January 2013 and December 2018. Cases were divided into trainees (TRN and ATT groups based on the experience of the operating surgeon. The primary outcome measures were 30-day morbidity and mortality. Preoperative patients' clinical characteristics, intraoperative findings, operative times, and postoperative hospitalization were compared. Operative times were used to extrapolate learning curves and evaluate the effects of changes in faculty using CUSUM charts. A propensity score matching analysis was performed to reduce differences between cohorts regarding both preoperative characteristics and intraoperative findings. A total of 1173 patients undergoing LA for acute appendicitis were included, of whom 521 (45%) in the TRN group and 652 (55%) in the ATT group. No significant differences were found between the two groups in terms of complication rates, operative times and length of hospital stay. However, CUSUM chart analysis showed decreased operating times in the TRN group. Operative times improved more quickly for advanced cases. The results of this study indicate that LA can be performed by trainees without detrimental effects on clinical outcomes, procedural safety, and operative times. However, the learning curve is longer than previously acknowledged.

Operating Room Times For Teaching and Nonteaching Cases are Converging: Less Time for Learning?

OBJECTIVE

To compare differences in operating room (OR) times between teaching and nonteaching cases across calendar years. We hypothesize that time devoted to intraoperative resident education is decreasing, therefore, OR times for teaching and nonteaching cases will be converging.

BACKGROUND

Teaching cases take longer than similar nonteaching cases, in part due to intraoperative resident education. Pressures to improve OR efficiency and patient safety may threaten resident education and leave less time for intraoperative learning; however, the magnitude of impact is unknown.

SETTING/PARTICIPANTS

National Surgical Quality Improvement Program (NSQIP) deidentified national databases from 2006 to 2012, queried for 30 most common General surgery procedures and case teaching status (i.e., teaching vs. nonteaching cases).

DESIGN

The NSQIP database was retrospectively reviewed to identify the 30 most common General Surgery procedures. Teaching cases included all operations in which a resident participated. Multivariable regression analyses were constructed to determine the impact of resident involvement on OR times, controlling for year, resident participation, procedure, and patient demographics and comorbidities. Difference-in-difference analysis was performed to assess OR time differences between teaching and nonteaching cases across calendar years and within subpopulations.

RESULTS

A total of 693,223 cases met inclusion criteria. Average overall OR times were 98.89 minutes (teaching) vs. 74.22 minutes (nonteaching), with a difference of 24.67 minutes (95% confidence interval [CI] 24.34-24.99 minutes, p < 0.001). In multivariable analyses, the difference between teaching and nonteaching cases was 21.94 minutes (95% CI = 21.11-22.76) in 2006 and 13.95 minutes (95% CI = 10.62-17.28) in 2012, with a difference-in-difference of 7.99 minutes per case. A similar trend was observed across individual PGYs and several individual procedures.

CONCLUSIONS

OR times for teaching and nonteaching cases converged by approximately 8 minutes per general surgery procedure during the 7-year study period, representing a 36% reduction in the difference between groups. We must seek to better understand the source of this convergence, and in doing so ensure to preserve and enhance the intraoperative learning experience of surgical trainees.

Three years mortality analysis in general surgery patients

Objective:

Surgical patient mortality is progressively being measured for providing better management and care in different healthcare systems world-wide. The aim of this study was to assess mortality within a surgical department and to evaluate components associated with surgical and non- surgical deaths.

Methods:

We retrospectively collected data including all admissions, both operative and non-operative, surgical procedures and reason of admission (for non-operative) and mortalities within three-year period (2015-2017) from Surgical Unit-2, JPMC Karachi. We assessed type of operations, admission, patient related factors including age, sex, co-morbid factors, reason, time and onset of presentation, operative notes, events, clinical cause and date/ time of death.

Results:

The total admissions of 5730 patients were observed in surgical ward-2 during the period of 1^st of January 2015 and 31^st of December 2017. There were a total of 291 deaths during this period (5.07% overall mortality rate). GIT related (peritonitis/ obstruction) (58.41%), biliarytract/ pancreatic causes (10.9%), road traffic accidents/ blunt trauma (7.21%), firearm injuries (1.71%) followed by GIT malignancies (4.81%) and Non-GIT malignancies (2.06%) were observed to be the main/ leading causes of death. Of the 291 deaths, males were 179 (6.70%) and females were 112 (3.66%). Male to female ratio of morality came out to be 1.6:1. The cause of death in our patients was sepsis (58.41%), cardiopulmonary arrest (13.0%), trauma/ gunshot injuries 8.93%, advanced malignancies (6.87%), pulmonary embolism (6.18%), myocardial infarction (5.49%) and post op bleeding (1.03%). Mortality due to delayed presentation of patient i.e. after five days of onset of symptoms (62.88%), Surgical decision/ exploration after 24 hours (33.67%). The lack of availability of ICU/ HDU in hospital contributed (51.01%) to the total surgical mortality.

Conclusions:

As per the study of three years (2015-2017) a fluctuating mortality pattern is observed. The increment of death was mainly among the unavoidable deaths such as GIT and Non GIT related sepsis, advanced malignancies, trauma and firearm injuries, pulmonary embolism myocardial infarction, a moderate role has also been played by miscellaneous group of patients. Delayed presentation of the patients after appearance of first symptom/ symptoms, delayed surgical decision/ exploration also came out to be significantly important factors in our studies elaborating the major difference in mortality rate.

Is Chief Resident Autonomy Safe for Patients? An Analysis of Quality in Training Initiative (QITI) Data to Assess Chief Resident Performance

OBJECTIVE

A chief resident service (CRS) provides a unique environment to assess competence throughout all aspects of patient care. The American College of Surgeons National Surgical Quality Improvement Program and Quality in Training Initiative databases are utilized to assess patient outcomes by individual residents with institutional and national comparisons. We hypothesized that residents on the CRS would have equivalent patient care outcomes to peers not on CRS and to chief residents nationally.

DESIGN

An institutional National Surgical Quality Improvement Program database was queried from 2014 to 2019 for operations performed on the CRS. Thirty-day complications were compared between CRS and non-CRS postgraduate year (PGY)-5 residents. Quality in Training Initiative reports were used to compare residents on CRS to national PGY-5 residents. Statistical analysis included chi-square tests, and multivariate logistic regression.

SETTING

Independent academic medical center.

PARTICIPANTS

Chief general surgery residents.

RESULTS

A total of 1031 cases were included in the analysis; 562 while off CRS and 469 while on CRS. Thirty-day outcomes were similar for CRS vs non-CRS cases for any complication (8% vs 12%, p = 0.05), unplanned readmissions (6% vs 5%, p = 0.58), and mortality (2% vs 2%, p = 0.99). Adjusting for patient and operative risk factors and procedure type, the rate of any complication after an operation on CRS vs off CRS was similar (odds ratio = 1.46, 95%confidence interval 0.82-2.60; p = 0.20). CRS residents had higher rates of postoperative renal failure (1.3% vs 0.5%, p = 0.008), but lower rates of organ space surgical site infection (0.6% vs 2.9%, p < 0.001), myocardial infarction (0 vs 0.6%, p = 0.04), pneumonia (0.3% vs 1.6%, p = 0.006), septic shock (0.1% vs 1.0%, p = 0.02), transfusion (2.7% vs 8.3%, p < 0.001), and fewer unplanned readmissions (6.1% vs 8.4%, p = 0.029) when compared to PGY-5 residents nationally.

CONCLUSIONS

Patient care outcomes provided by PGY-5 residents on a CRS are comparable to those on non-CRS rotations and to PGY-5 residents nationally.

Laparoscopic Appendectomy Performed by Surgical Interns: Is it Too Early?

BACKGROUND

Laparoscopic appendectomy (LA) is a common procedure among surgical trainees. However, first-year residents' involvement in this procedure is scarcely studied. We aimed to determine the safety and outcomes of LA performed by surgical interns early in their first year of surgical training.

MATERIALS AND METHODS

A retrospective review of all patients who underwent LA for acute appendicitis from 2006 to 2019 was performed. All patients operated by surgical interns were included. The sample was divided into 2 groups: LA performed during the first (G1) and last 3 months (G2) of their first year of residency. Demographics, operative variables, and postoperative outcomes were compared between groups.

RESULTS

A total of 2009 LA were performed during the study period; 1647 (82%) were done by surgical interns. A total of 934 LA were performed at both ends of the year; 505 belonged to G1 and 429 to G2. Each surgical intern performed a mean of 40 LA. Demographics, complicated appendicitis rates, and presence of peritonitis were comparable between groups. Operative time was longer in G1 (G1: 61 vs. G2: 52 min, P<0.0001). Major morbidity (G1: 2.1% vs. G2: 3.4%, P=0.2), postoperative intra-abdominal abscess rates (G1: 2.8% vs. G2: 2.8%, P=0.66), median length of hospital stay (G1: 1.9 vs. G2: 1.8 d, P=0.59), and readmission rates (G1: 1.6% vs. G2: 2%, P=0.73) were similar between groups. There was no mortality in the series.

CONCLUSIONS

LA can be safely performed by supervised surgical interns early in their training. Despite a longer operative time, postoperative outcomes were favorable and similar as those achieved at the end of surgical internship.

Single-incision laparoscopic appendectomy is a safe procedure for beginners to perform: experience from 1948 cases

BACKGROUND

Single-incision laparoscopic appendectomy (SIL-A) has recently become an option for treating appendicitis. The aim of this study was to evaluate the safety, feasibility, and surgical outcomes of SIL-A by residents and surgeons during the learning period.

METHODS

A total of 1948 consecutive patients who underwent SIL-A from May 2008 to November 2014 were studied retrospectively. Surgeries were performed by residents and eight surgeons. Prior to the first case, surgeons and residents had been trained in a training protocol during the learning period. Three initial cases of SIL-A were performed under the supervision of experienced surgeons. Patients were divided into two groups: group 1 (learning period, n = 483), the first 40 cases by each surgeon and resident; and group 2 (experienced period, n = 1465), cases after the 40th procedure performed by each surgeon. Surgical results were compared between the two groups by performing propensity score matching analysis.

RESULTS

After propensity score matching, there was no significant difference in patient demographics and characteristics of appendicitis between the two groups. The operating time was longer in group 1 than in group 2 (45.3 ± 18.0 vs. 33.9 ± 16.1 min, p < 0.001). The morbidity rate (7.0% vs. 6.5%, p = 0.795) was similar between the two groups. Readmission rate (2.1% vs. 1.3%, p = 0.414) and reoperation rate (0.8% vs. 0.8%, p = 0.348) were also similar between the two groups. However, the rate of incisional hernia occurrence (0.6% vs. 0%, p = 0.066) tended to be larger in group 1 than in group 2 without showing a significant difference.

CONCLUSION

SIL-A is a technically feasible and safe procedure when it is performed by residents and surgeons during learning period under an appropriate training protocol. However, residents and surgeons in the learning period should perform it carefully to prevent incisional hernias.

The impact of surgical simulation on patient outcomes: a systematic review and meta-analysis

The use of simulation in surgical training is ever growing. Evidence suggests such training may have beneficial clinically relevant effects. The objective of this research is to investigate the effects of surgical simulation training on clinically relevant patient outcomes by evaluating randomized controlled trials (RCT). PubMed was searched using PRISMA guidelines: "surgery" [All Fields] AND "simulation" [All Fields] AND "patient outcome" [All Fields]. Of 119 papers identified, 100 were excluded for various reasons. Meta-analyses were conducted using the inverse-variance random-effects method. Nineteen papers were reviewed using the CASP RCT Checklist. Sixteen studies looked at surgical training, two studies assessed patient-specific simulator practice, and one paper focused on warming-up on a simulator before performing surgery. Median study population size was 22 (range 3-73). Most articles reported outcome measures such as post-intervention Global Rating Scale (GRS) score and/or operative time. On average, the intervention group scored 0.42 (95% confidence interval 0.12 to 0.71, P = 0.005) points higher on a standardized GRS scale of 1-10. On average, the intervention group was 44% (1% to 87%, P = 0.04) faster than the control group. Four papers assessed the impact of simulation training on patient outcomes, with only one finding a significant effect. We found a significant effect of simulation training on operative performance as assessed by GRS, albeit a small one, as well as a significant reduction to operative time. However, there is to date scant evidence from RCTs to suggest a significant effect of surgical simulation training on patient outcomes.

How Does a New General Surgery Residency Program's Junior Residents Impact Hospital Efficiency and Productivity?

OBJECTIVE

The general surgery workforce deficit is projected to grow to 15% to 21% by 2050. An estimated 6.6% increase to existing general surgery residency (GSR) programs is needed to meet this shortfall. The purpose of this study was to examine the impact of a new GSR program on efficiency and productivity at a regional healthcare center.

STUDY DESIGN

An institutional database was retrospectively queried for all GSR related procedures between July 2015 and June 2018. Procedures done prior to GSR initiation (pre-GSR) were compared to those done after (post-GSR). Univariate and multivariate analyses were performed.

RESULTS

We reviewed 10,617 procedures (6365 pre-GSR vs. 4252 post-GSR). Patients had lower preoperative Hierarchical Condition Category scores in the post-GSR group (0.71 vs. 0.58, p < 0.01). Operative times increased post-GSR (101.7 vs. 109.1 minutes, p < 0.01), but length of stay decreased (6.4 vs. 5.5 days, p = 0.01). Thirty-day readmissions (4.0% vs. 3.4%, p = 0.11) were comparable, but reoperations significantly decreased post-GSR (10.1% vs. 8.6%, p = 0.01). Average hospital costs remained unchanged ($10,765 vs. $10,140, p = 0.12). Multivariate analysis revealed no statistical difference in operative times, length of stay, 30-day readmissions and reoperations, and hospital costs between the 2 groups. Subset analysis based on surgical service also showed no statistical difference. Productivity increased on the general surgery service post-GSR (7.1 vs. 7.8 cases per day, p = 0.02). Patient satisfaction increased post-GSR (76% vs. 81%, p = 0.31), but without statistical significance.

CONCLUSION

The initiation of a new GSR program did not negatively impact operative times, length of stay, 30-day readmissions and reoperations, hospital costs, case volume, or patient satisfaction.

Evaluating the impact of resident involvement during the laparoscopic nephrectomy

Introduction

Laparoscopic nephrectomy (LN) is the most performed laparoscopic procedure by urologic residents (Res). A large amount of data exists on laparoscopic nephrectomies in terms of safety and surgical outcomes, but only a little is known about the influence of residents. The purpose of this study was to evaluate this influence on the clinical outcome of a laparoscopic nephrectomy.

Material and methods

Retrospectively, patients who had undergone a LN between 2010 and 2018 were assessed. Data included patient demographics, date of surgery, pre- and postoperative results and complications. The patients who had undergone a LN were divided into two groups: one where residents were involved and another group where only a staff surgeon (Sur) performed the operation. All training residents had a questionnaire sent to them to evaluate their role during the LN.

Results

A total of 229 patients met the study criteria, of which 78 patients were operated together with a resident and 151 by a staff surgeon alone. Both groups were homogeneous in terms of age, comorbidities, left/right sided LN and tumor-stage. Between these two groups, no significant differences were observed in median estimated blood loss (Res 87 ml vs. Sur 100 ml), intraoperative adverse events (Res 10.3% vs. Sur 6% p = 0.24), conversion to open surgery (Res 6.4% vs. Sur 6%) and high-grade postoperative complications (Res 3.9% vs. Sur 4.6%). However, when a resident participated, the LN lasted on average 20 minutes longer (Res mean 130 min vs. Sur 110 min p ≤0.001).

Conclusions

Our data shows that involvement of a resident in laparoscopic nephrectomy has no effect on the clinical outcome. Therefore, it is safe to perform a laparoscopic nephrectomy together with a resident, but it is important to take the additional surgical time into account.

Risk factors for serious morbidity, prolonged length of stay and hospital readmission after laparoscopic appendectomy - results from Pol-LA (Polish Laparoscopic Appendectomy) multicenter large cohort study

Laparoscopic appendectomy (LA) for treatment of acute appendicitis has gained acceptance with its considerable benefits over open appendectomy. LA, however, can involve some adverse outcomes: morbidity, prolonged length of hospital stay (LOS) and hospital readmission. Identification of predictive factors may help to identify and tailor treatment for patients with higher risk of these adverse events. Our aim was to identify risk factors for serious morbidity, prolonged LOS and hospital readmission after LA. A database compiled information of patients admitted for acute appendicitis from eighteen Polish and German surgical centers. It included factors related to the patient characteristics, peri- and postoperative period. Univariate and multivariate logistic regression models were used to identify risk factors for serious perioperative complications, prolonged LOS, and hospital readmissions in acute appendicitis cases. 4618 laparoscopic appendectomy patients were included. First, although several risk factors for serious perioperative complications (C-D III-V) were found in the univariate analysis, in the multivariate model only the presence of intraoperative adverse events (OR 4.09, 95% CI 1.32-12.65, p = 0.014) and complicated appendicitis (OR 3.63, 95% CI 1.74-7.61, p = 0.001) was statistically significant. Second, prolonged LOS was associated with the presence of complicated appendicitis (OR 2.8, 95% CI: 1.53-5.12, p = 0.001), postoperative morbidity (OR 5.01, 95% CI: 2.33-10.75, p < 0.001), conversions (OR 6.48, 95% CI: 3.48-12.08, p < 0.001) and reinterventions after primary procedure (OR 8.79, 95% CI: 3.2-24.14, p < 0.001) in the multivariate model. Third, although several risk factors for hospital readmissions were found in univariate analysis, in the multivariate model only the presence of postoperative complications (OR 10.33, 95% CI: 4.27-25.00), reintervention after primary procedure (OR 5.62, 95% CI: 2.17-14.54), and LA performed by resident (OR 1.96, 95% CI: 1.03-3.70) remained significant. Laparoscopic appendectomy is a safe procedure associated with low rates of complications, prolonged LOS, and readmissions. Risk factors for these adverse events include complicated appendicitis, postoperative morbidity, conversion, and re-intervention after the primary procedure. Any occurrence of these factors during treatment should alert the healthcare team to identify the patients that require more customized treatment to minimize the risk for adverse outcomes.

See one, do one, but never teach one? An analysis of resident teaching assist cases under various levels of attending supervision

BACKGROUND

Surgical training has traditionally relied on increasing levels of resident autonomy. We sought to analyze the outcomes of senior resident teaching assist (TA) cases performed with a structured policy including varying levels of staff supervision.

METHODS

Retrospective review at a military medical center of TA cases from 2009 to 2014. The level of staff supervision included staff scrubbed (SS), staff present and not scrubbed (SP), or staff not present but available (NP). Operative variables were analyzed. An anonymous survey of residents and attendings at 6 military programs regarding experience and opinions on TA cases was distributed.

RESULTS

389 TA cases were identified. The majority (52%) were performed as NP. Operative times were shorter for NP cases (p < 0.05). Overall complication rate and length of stay were not different between groups (p > 0.05). Survey results demonstrated agreement amongst staff and residents that allowing selective NP was critical for achieving resident competence.

CONCLUSION

There were no identified adverse effects on intraoperative or postoperative complications. This practice is a critical component of training senior residents to transition to independent practice.
