Resident versus no resident: a single institutional study on operative complications, mortality, and cost

The Effect of Resident Involvement in Hip Fracture Surgery: An Analysis of a Single Institution Before and After the Addition of an Orthopaedic Surgical Residency

INTRODUCTION

Hip fractures are common injuries that are associated with serious morbidity/mortality in the elderly and represent a substantial financial burden to healthcare systems. Previous studies demonstrated that resident involvement in orthopaedic surgeries is associated with increased surgical time and cost, with equivocal or worse outcomes. This study evaluated outcomes of hip fracture surgery at one institution, before and after the introduction of an orthopaedic residency program.

METHODS

A retrospective chart review divided patients who underwent hip fracture surgery between January 2015 and January 2018 into two groups based on resident involvement. Outcomes including surgical time, length of stay (LOS), readmission rate, and direct/indirect costs were compared as were the American Society of Anesthesiologists physical status score and procedure conducted.

RESULTS

Six hundred sixty-two hip fracture surgeries were performed in 36 months. Residents were engaged in 303 cases (45.8%) with no notable differences in the two groups regarding American Society of Anesthesiologists score, procedure conducted, or readmission rate. With resident involvement, surgical time was significantly longer (91.2 versus 78.9 minutes, P-value = 0.004), whereas LOS was significantly shorter (5.2 versus 5.6 days, P-value = 0.003). Finally, there were significant reductions in direct costs (8% reduction; P < 0.001) and OR implant costs (12% reduction; P < 0.001), but significant increase in indirect costs (7% increase; P < 0.001).

DISCUSSION

Surgical experience is critical in orthopaedic training. There are concerns regarding potential negative effects of resident involvement on surgical outcomes and healthcare costs. While resident involvement was associated with slightly increased surgical times and indirect costs, it also led to decreased LOS and direct costs. We believe this is the first study to compare patient outcomes at one institution before and after resident involvement. Our findings demonstrated, compared with attendings alone, resident involvement resulted in an overall improvement rather than compromise in patient care.

Declining Resident Surgical Autonomy and Improving Surgical Outcomes: Correlation Does Not Equal Causality

OBJECTIVE

The volume of cases that residents perform independently have decreased leaving graduating chief residents less prepared for independent practice. Outcomes are not worse when residents are given autonomy with appropriate supervision, however it is unknown if outcomes are worsening with decreasing operative autonomy experience. We hypothesize that resident autonomous cases parallel the improving outcomes in surgical care over time, however, are less complex and on lower acuity patients.

DESIGN

Retrospective study utilizing the Veterans Affairs Surgical Quality Improvement Program (VASQIP) database.

SETTING

Operative cases performed on teaching services within the VASQIP database from July 1, 2004 to September 30, 2019, were included.

PARTICIPANTS

All adult patients who underwent a surgical procedure from July 1, 2004, to September 30, 2019, at a VA hospital on a service that included residents were initially included. After inclusions and exclusions, there were 1,346,461 cases. Cases were divided into 3 sequential 5 year eras (ERA 1: 2004-2008 n = 415,614, ERA 2: 2009-2013 n = 478,528, and ERA 3: 2014-2019 n = 452,319). The main exposure of interest was level of resident supervision, coded at the time of procedure as: attending primary surgeon (AP); attending and resident (AR), or resident primary with the attending supervising but not scrubbed (RP). We compared 30 day all-cause mortality, composite morbidity, work relative value unit (wRVU), hospital length of stay, and operative time between each ERA for RP cases, as well as within each ERA for RP cases compared to AR and AP cases.

RESULTS

There was a progressive decline in the rate of RP cases in each successive ERA (ERA 1: 58,249 (14.0%) vs ERA 2: 47,891 (10.0%) vs ERA 3: 35,352 (7.8%), p < 0.001). For RP cases, patients were progressively getting older (60 yrs [53-71] vs 63 yrs [54-69] vs 66 yrs [57-72], p < 0.001) and sicker (ASA 3 58.7% vs 62.5% vs 66.2% and ASA 4/5 8.4% vs 9.6% vs10.0%, p < 0.001). Odds of mortality decreased in each ERA compared to the previous (aOR 0.71 [0.62-0.80] ERA 2 vs ERA 1 and 0.82 [0.70-0.97] ERA 3 vs ERA 2) as did morbidity (0.77 [0.73-0.82] ERA 2 vs ERA 1 and 0.72 [0.68-0.77] ERA 3 vs ERA 2). Operative and length of stay also decreased while wRVU stayed unchanged. When comparing RP cases to AP and AR within each ERA, RP cases tended to be on younger and healthier patients with a lower wRVU, particularly compared to AR cases. Mortality and morbidity were no different or better in RP compared to AR and AP.

CONCLUSIONS

Despite resident autonomy decreasing, outcomes in cases where they are afforded autonomy are improving over time. This despite RP cases being on sicker and older patients and performing roughly the same complexity of cases. They also continue to perform no worse than cases with higher levels of supervision. Efforts to increase surgical resident operative autonomy are still needed to improve readiness for independent practice.

Association of Resident Independence With Short-term Clinical Outcome in Core General Surgery Procedures

Importance

Prior studies evaluating the effect of resident independence on operative outcome draw from case mixes that cross disciplines and overrepresent cases with low complexity. The association between resident independence and clinical outcome in core general surgical procedures is not well defined.

Objective

To evaluate the level of autonomy provided to residents during their training, trends in resident independence over time, and the association between resident independence in the operating room and clinical outcome.

Design, Setting, and Participants

Using the Veterans Affairs Surgical Quality Improvement Program database from 2005 to 2021, outcomes in resident autonomy were compared using multivariable logistic regression and propensity score matching. Data on patients undergoing appendectomy, cholecystectomy, partial colectomy, inguinal hernia, and small-bowel resection in a procedure with a resident physician involved were included.

Exposures

Resident independence was graded as the attending surgeon scrubbed into the operation (AS) or the attending surgeon did not scrub (ANS).

Main Outcomes and Measures

Outcomes of interest included rates of postoperative complication, severity of complications, and death.

Results

Of 109 707 patients who met inclusion criteria, 11 181 (10%) underwent operations completed with ANS (mean [SD] age of patients, 61 [14] years; 10 527 [94%] male) and 98 526 (90%) operations completed with AS (mean [SD] age of patients, 63 [13] years; 93 081 [94%] male). Appendectomy (1112 [17%]), cholecystectomy (3185 [11%]), and inguinal hernia (5412 [13%]) were more often performed with ANS than small-bowel resection (527 [6%]) and colectomy (945 [4%]). On multivariable logistic regression adjusting for procedure type, age, body mass index, functional status, comorbidities, American Society of Anesthesiologists class, wound class, case priority, admission status, facility type, and year, factors associated with a complication included increasing age (adjusted odds ratio [aOR], 1.19 [95% CI, 1.16-1.22]), emergent case priority (aOR, 1.41 [95% CI, 1.33-1.50]), and resident independence (aOR, 1.12 [95% CI, 1.03-1.22]). On propensity score matching, AS cases were score matched 1:1 to ANS cases based on the variables listed above. Comparing matched cohorts, there was no difference in complication rates (817 [7%] vs 784 [7%]) or death (91 [1%] vs 102 [1%]) based on attending physician involvement.

Conclusions and Relevance

Core general surgery cases performed by senior-level trainees in such a way that the attending physician is not scrubbed into the case are being done safely with no significant difference in rates of postoperative complication.

Impact of surgeon and hospital factors on length of stay after colorectal surgery systematic review

Background

Although length of stay (LOS) after colorectal surgery (CRS) is associated with worse patient and system level outcomes, the impact of surgeon and hospital-level factors on LOS after CRS has not been well investigated. The aim of this study was to synthesize the evidence for the impact of surgeon and hospital-level factors on LOS after CRS.

Methods

A comprehensive database search was conducted using terms related to LOS and CRS. Studies were included if they reported the effect of surgeon or hospital factors on LOS after elective CRS. The evidence for the effect of each surgeon and hospital factor on LOS was synthesized using vote counting by direction of effect, taking risk of bias into consideration.

Results

A total of 13 946 unique titles and abstracts were screened, and 69 studies met the inclusion criteria. All studies were retrospective and assessed a total of eight factors. Surgeon factors such as increasing surgeon volume, colorectal surgical specialty, and progression along a learning curve were significantly associated with decreased LOS (effect seen in 87.5 per cent, 100 per cent, and 93.3 per cent of studies respectively). In contrast, hospital factors such as hospital volume and teaching hospital status were not significantly associated with LOS.

Conclusion

Provider-related factors were found to be significantly associated with LOS after elective CRS. In particular, surgeon-related factors related to experience specifically impacted LOS, whereas hospital-related factors did not. Understanding the mechanisms underlying these relationships may allow for tailoring of interventions to reduce LOS.

The Impact of Resident Involvement on Outcomes and Costs in Elective Hand and Upper Extremity Surgery

PURPOSE

The purpose of this study was to assess the impact of resident involvement on periprocedural outcomes and costs after common procedures performed at an academic hand surgical practice.

METHODS

A retrospective review was performed in all patients undergoing 7 common elective upper extremity procedures between January 2008 and December 2018: carpal tunnel release, distal radius open reduction and internal fixation (ORIF), trigger finger release, thumb carpometacarpal arthroplasty, phalanx closed reduction and percutaneous pinning, cubital tunnel release, and olecranon ORIF. The medical record was reviewed to determine the impact of surgical assistants (resident, fellow, or physician assistant) on periprocedural outcomes, periprocedural costs, and 1-year postoperative outcomes. The involvement of surgical trainees operating under direct supervision was compared with the entire operation performed by the attending surgeon with a physician assistant present.

RESULTS

A total of 396 procedures met the inclusion criteria. Analysis of the whole study sample revealed low rates of intraoperative complications, wound complications, medical complications, readmissions, and mortality. Subgroup analysis of carpal tunnel releases revealed significantly greater tourniquet times for residents compared with physician assistants (7 ± 2 min, 6 ± 1 min), as well as longer overall operating room times for residents compared to fellows or physician assistants (17 ± 5 min, 13 ± 3 min, 12 ± 3 min). Operating room times for distal radius ORIF were significantly greater among residents compared to fellows or physician assistants (68 ± 19 min, 57 ± 17 min, 56 ± 14 min). There were no differences in any other perioperative metrics or periprocedural costs for the trigger finger release or cubital tunnel release cohorts.

CONCLUSIONS

Resident involvement in select upper extremity procedures can lengthen operative times but does not have an impact on blood loss or operating room costs.

CLINICAL RELEVANCE

Surgeons should be aware that having a resident assistant slightly increases operative times in elective hand surgery.

Resident Involvement in Inguinal Hernia Repair is Safe but Associated With Increased Operative Time

INTRODUCTION

Understanding how resident participation in surgery affects outcomes is critical for academic surgeons. The purpose of this study was to evaluate if resident participation was associated with adverse outcomes for inguinal hernia repair.

METHODS

We used the Veterans Affairs Surgical Quality Improvement Program to look at 61,737 patients aged ≥18 y who had open inguinal hernia repairs from 1998 to 2018. Propensity weighting was used to compare postoperative complications and operative time for patients having surgery performed by an attending alone versus attending with a postgraduate year (PGY) 1, 3, or 5 residents.

RESULTS

There were 29,806 hernias (48%) repaired by an attending, 12,024 (19%) by an intern, 9008 (15%) by a PGY-3 resident, and 10,898 (18%) by a PGY-5 resident. After propensity weighting, there was a 0.13% (95% CI -0.11% to 0.38%, P = 0.29) increase in complications with PGY-1 participation compared to cases performed by attendings alone, a 0.3% increase (95% CI 0.01% to 0.59%, P = 0.04) for PGY-3 residents, and a 0.4% increase (95% CI 0.11% to 0.69%, P = 0.007) for PGY-5 residents. There was also an increase in operative time of 26 min (95% CI 25 to 27, P < 0.001) with PGY-1 participation, 19 min (95% CI 18 to 20, P < 0.001) with PGY-3 participation, and 23 min (95% CI 22 to 24, P < 0.001) with PGY-5 participation.

CONCLUSIONS

Resident involvement in inguinal hernia surgery was associated with a significant increase in operative time but had a minimal impact on postoperative complications. Although resident participation in hernia surgery is safe, surgical programs should focus on enhancing operative efficiency for residents.

Resident Involvement in Hip Arthroscopy Procedures Does Not Affect Short-Term Surgical Outcomes

Purpose

To evaluate whether the presence of residents in hip arthroscopy (HA) procedures affects short-term surgical outcomes.

Methods

The American College of Surgeons National Surgical Quality Improvement Program Database was used to identify patients who underwent HA from 2006 to 2012. Demographic and 30-day outcome variables were compared between cohorts of patients with and without residents. Multivariate logistic regression was used to identify whether resident involvement was an independent risk factor for adverse outcomes. Propensity score matching was performed to control for all demographic and intraoperative variables.

Results

A total of 869 patients (59.7% female) were included in this study, 626 of which reported data on resident involvement. Patients were mostly White (73.4% of cases without a resident, 51.8% with a resident, P < .05). Those with residents were younger (P = .016), had lower modified 5-item frailty index (mFI-5) scores (P = .028), and had fewer cardiac comorbidities (P = .008). There was no difference in diabetic status, dyspnea symptoms, history of chronic obstructive pulmonary disease, renal comorbidity, neurologic comorbidity, cumulative comorbidities, history of bleeding disorders, inpatient vs. outpatient treatment, preoperative functional status, smoking history, and steroid use for chronic conditions. There was no difference in all complications, operative time, length of stay, reoperation, readmission, wound complication, venous thromboembolism, blood transfusions, or sepsis. Propensity score match for demographic and intraoperative differences found no association between resident involvement and increased complications. Resident involvement was not an independent risk factor for all complications studied.

Conclusion

Resident involvement in HA procedures was not a risk factor for 30-day complications between 2006 and 2012. Resident involvement did not increase the risk of adverse outcomes, readmission, reoperation, or length of stay, nor did it significantly increase operative times.

Short-term outcome of isolated lateral malleolar fracture treatment is independent of hospital trauma volume or teaching status: a nationwide retrospective cohort study

Introduction

In light of current discussions about centralisation and teaching in medicine, we wanted to investigate the differences in in-hospital outcomes after surgical treatment of isolated ankle fractures, taking into account high-volume centres (HVCs) and low-volume centres (LVCs) and teaching procedures.

Methods

A retrospective analysis of malleolar fractures recorded in a National Quality Assurance Database (AQC) from the period 01-01-1998 to 31-12-2018 was carried out. Inclusion criteria were isolated, and operatively treated lateral malleolar fractures (ICD-10 Code S82.6 and corresponding procedure codes). Variables were sought in bivariate and multivariate analyses. A total of 6760 cases were included. By dividing the total cases arbitrarily in half, 12 HVCs (n = 3327, 49%) and 56 LVCs (n = 3433, 51%) were identified.

Results

Patients in HVCs were younger (48 vs. 50 years old), had more comorbidities (26% vs. 19%) and had more open fractures (0.48% vs. 0.15%). Open reduction and internal fixation was the most common operative treatment at HVCs and LVCs (95% vs. 98%). A more frequent use of external fixation (2.5% vs. 0.55%) was reported at HVCs. There was no difference in mortality between treatment at HVCs and LVCs. A longer hospitalisation of 7.2 ± 5 days at HVCs vs. 6.3 ± 4.8 days at LVCs was observed. In addition, a higher rate of complications of 3.2% was found at HVCs compared to 1.9% at LVCs. The frequency of teaching operations was significantly higher at HVCs (30% vs. 26%). Teaching status had no influence on mortality or complications but was associated with a prolonged length of stay and operating time.

Conclusion

We found significant differences between HVCs and LVCs in terms of in-hospital outcomes for ankle fractures. These differences could be explained due to a more severely ill patient population and more complex (also open) fracture patterns with resulting use of external fixation and longer duration of surgery. However, structural and organisational differences, such as an extended preoperative stays at HVCs and a higher teaching rate, were also apparent. No difference in mortality could be detected.

Laparoscopic cholecystectomy performed by general surgery residents. Is it safe? How much does it cost?

OBJECTIVE

to evaluate the effectiveness and safety of laparoscopic cholecystectomies performed by residents of the first and second-year of a general surgery residency program. We studied the primary total cost of treatment and complication rates as primary outcomes, comparing the groups operated by senior and resident surgeons.

METHODS

this was a retrospective cohort study of patients who underwent laparoscopic cholecystectomy performed in a training hospital of large surgical volume in Brazil, in the period between June 1, 2018 and May 31, 2019. The study population comprised patients who underwent elective cholecystectomy due to uncomplicated chronic calculous cholecystitis or to the presence of gallbladder polyps with surgical indication. We divided the cases into three groups, based on the graduation of the main surgeon at the time of the procedure: first-year residents (R1), second-year residents (R2), and trained general surgeons (GS).

RESULTS

during the study period, 1,052 laparoscopic cholecystectomies were performed, of which 1,035 procedures met the inclusion criteria, with 78 (7.5%) patients operated on with the participation of first-year residents (R1), 500 (48.3%) patients with the participation of second-year residents (R2), and 457 (44.2%) with the participation of senior surgeons only. There was no difference in conversion rates, complications, and reporting of adverse events between groups. We observed a significant difference regarding hospitalization costs (p = 0.003), with a higher mean for the patients operated with the participation of R1, of US$ 2,671.13, versus US$ 2,414.60 and US$ 2,396.24 for the procedures performed by senior surgeons and R2, respectively.

CONCLUSIONS

laparoscopic cholecystectomy with the participation of residents is safe, even in their first years of training. There is an additional cost of about 10% in the treatment of patient operated with the participation of first-year residents. There was no significant difference in the cost of the group operated by second-year residents.

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.

Trainee-led emergency laparotomy operating

Background

To achieve completion of training in general surgery, trainees are required to demonstrate competency in common procedures performed at emergency laparotomy. The aim of this study was to describe the patterns of trainee-led emergency laparotomy operating and the association between postoperative outcomes.

Methods

Data on all patients who had an emergency laparotomy between December 2013 and November 2017 were extracted from the National Emergency Laparotomy Audit database. Patients were grouped by grade of operating surgeon: trainee (specialty registrar) or consultant (including post-Certificate of Completion of Training fellows). Trends in trainee operating by deanery, hospital size and time of day of surgery were investigated. Univariable and adjusted regression analyses were performed for the outcomes 90-day mortality and return to theatre, with analysis of patients in operative subgroups segmental colectomy, Hartmann's procedure, adhesiolysis and repair of perforated peptic ulcer disease.

Results

The study cohort included 87 367 patients. The 90-day mortality rate was 15·1 per cent in the consultant group compared with 11·0 per cent in the trainee group. There were no increased odds of death by 90 days or of return to theatre across any of the operative groups when the operation was performed with a trainee listed as the most senior surgeon in theatre. Trainees were more likely to operate independently in high-volume centres (highest- versus lowest-volume centres: odds ratio (OR) 2·11, 95 per cent c.i. 1·91 to 2·33) and at night (00.00 to 07.59 versus 08.00 to 11.59 hours; OR 3·20, 2·95 to 3·48).

Conclusion

There is significant variation in trainee-led operating in emergency laparotomy by geographical area, hospital size and by time of day. However, this does not appear to influence mortality or return to theatre.

Teaching in the operating room: A risk for surgical site infections?

BACKGROUND/AIM

To investigate whether teaching procedures and surgical experience are associated with surgical site infection (SSI) rates.

METHODS

This prospective cohort study of patients undergoing general, orthopedic trauma and vascular surgery procedures was done between 2012 and 2015 at two tertiary care hospitals in Switzerland/Europe.

RESULTS

Out of a total of 4560 patients/surgeries, 1403 (30.8%) were classified as teaching operations. The overall SSI rate was 5.1% (n = 233). Teaching operations (OR 0.78, 95% CI 0.57-1.07, p = 0.120), junior surgeons (OR 0.80, 95% CI 0.55-1.15, p = 0.229) and surgical experience (OR 0.997, 95% CI 0.982-1.012, p = 0.676) were overall not independently associated with the odds of SSI. However, for surgeons' seniority and experience, these associations depended on the duration of surgery.

CONCLUSIONS

In procedures of shorter and medium duration, teaching procedures and junior as well as less experienced surgeons are not independently associated with increased odds of SSI.

Does Perceived Resident Operative Autonomy Impact Patient Outcomes?

OBJECTIVE

We investigated the association of perceived trainee autonomy with patient clinical outcomes following colorectal surgery.

DESIGN

This was a prospective multi-institutional study that consisted of surgery trainees completing a survey tool immediately after participating in colorectal resections to rate their self-perceived autonomy and case characteristics. Self-perception of autonomy was classified as observer, assistant, surgeon, or teacher. The completed trainee surveys were linked with patient information available through each hospital's internal NSQIP directory. The primary outcome was death and serious morbidity (DSM) and secondary outcome was 30-day readmissions. Separate mixed effects regression models were used to examine the association between perceived trainee autonomy and DSM or 30-day readmissions. Fixed effects were used to control for the effects of the training environment. The models were constructed to adjust for patient and trainee characteristics associated with each outcome independently.

SETTING

This study was conducted at 7 general surgery training programs (5 academic medical centers and 2 independent training programs) with general surgery or colorectal surgery services.

PARTICIPANTS

This study included a total of 63 residents and fellows rotating on surgery services that performed colorectal resections at the included 7 general surgery training programs from January until March 2016.

RESULTS

The 63 trainees that participated in this study completed 417 surveys with over a 95% response rate. National Surgical Quality Improvement Program (NSQIP) patient records were available for 67% (n = 273) of completed surveys. The clinical year of the trainees were 6.1% PGY 1/2, 36% Post graduate year (PGY) 3, 40.9% PGY 4/5, and 17% fellows. Residents perceived their participation in the case to be that of an observer in 9.2% of surveys, an assistant in 51.6% of surveys, and the surgeon/teacher in 39.3% of surveys. About 50% of patients were male, 80% were White, the majority had an American Society of Anesthesiologists classification of 3, almost half had prior abdominal surgery, and over 80% of surgeries were elective. The primary operation types performed were laparoscopic (40.3%) and open (35.9%) partial colectomies. The rate of DSM in patients was approximately 24% when trainees perceived their role as observers, 23% when trainees perceived their role as assistants, and 18% when trainees perceived their role as surgeons/teachers. After adjustment for patient, trainee, and training environment, we found that the perceived level of trainee autonomy of a surgeon/teacher was associated with a 4-fold lower rate of DSM (odds ratio: 0.23, confidence of interval: 0.05-0.97, p = 0.045) compared to observers. The rate of readmissions was approximately 20% when trainees perceived their role as observers, 14% when trainees perceived their role as assistants and 9% when trainees perceived their role as surgeons/teachers. After adjustment for patient, trainee, and training environment, we found that the perceived level of trainee autonomy of a surgeon/teacher was significantly associated with a 10-fold lower rate of 30-day readmissions (odds ratio: 0.09, confidence of interval: 0.01-0.70, p = 0.022) compared to observers.

CONCLUSIONS

There was an association between increased perceived trainee autonomy and improved patient outcomes, suggesting that when trainees identify with an increased role in the operation, patients may have improved care. Further research is needed to understand this association further.

The clinical outcomes of pediatric inguinal hernia repairs operated by surgical residents

BACKGROUND

Inguinal hernia is one of the most common surgical diseases, and surgical residents perform inguinal hernia repairs during pediatric surgery rotation. The aims of this study were to examine the clinical outcomes of pediatric inguinal herniorrhaphy performed by surgical residents and to assess the suitability for surgical training.

METHODS

We extracted data on elective unilateral inguinal hernia repairs performed in children between 2014 and 2018. All eligible cases were divided into surgical resident and attending surgeon groups according to the operator. We reviewed medical records retrospectively and compared some clinical indicators between the 2 groups.

RESULTS

Of 294 eligible cases, 163 were performed by 37 surgical residents and 131 were performed by 4 attending surgeons. The median operative times in the resident and attending surgeon groups were 30 and 19 min, respectively. Operative time was statistically longer in the resident group (p < 0.001). The complication and recurrence rates in the resident and attending surgeon groups were 11.0% and 11.5%, and 0% and 0.8%, respectively (p = 1.000 and p = 0.466).

CONCLUSION

Inguinal hernia repairs could be properly performed by surgical trainees with the assistance of attending surgeons. Hernia operation might provide good opportunities for surgical residents to practice basic surgical skills.

Impact of medical student involvement on outcomes following spine surgery: A single center analysis of 6485 patients

Medical student (MS) observation and assistance in the operating room (OR) is a critical component of medical education. Though participation in the operating room has many benefits to the medical student, the potential cost of these experiences to the patients must be taken into account. Other studies have shown differences in outcomes with resident involvement, but the effect of medical students in the OR has been poorly understood. The objective of this study was to understand how medical students and residents impacted surgical outcomes in posterior spinal fusions, anterior cervical discectomy and fusions (ACDFs), and lumbar discectomies. We conducted a retrospective study of patients undergoing posterior spinal fusions, ACDFs, and lumbar discectomies over 15 years. There were 6485 patients met the inclusion criteria of either undergoing a posterior fusion, ACDF or lumbar discectomy (1250 posterior fusion, 1381 ACDF, 3854 lumbar discectomies). Overall, little difference was observed when a medical student was present for surgical outcomes including length of stay, infection, and readmission. For ACDFs, having a medical student present had a significantly longer procedure durations (OR = 1.612, p = 0.001) than cases without. Besides slightly longer operative time (in posterior fusions), there were no major differences in outcomes when a medical student was present in the OR.

The presence of residents during orthopedic operation exerts no negative influence on outcome

BACKGROUND

Operative procedural training is a key component of orthopedic surgery residency. It is unclear how and whether residents participation in orthopedic surgical procedures impacts on post-operative outcomes.

SOURCES OF DATA

A systematic search was performed to identify articles in which the presence of a resident in the operating room was certified, and was compared with interventions without the presence of residents.

AREAS OF AGREEMENT

There is a likely beneficial role of residents in the operating room, and there is only a weak association between the presence of a resident and a worse outcome for orthopedic surgical patients.

AREAS OF CONTROVERSY

Most of the studies were undertaken in USA, and this represents a limit from the point of view of comparison with other academic and clinical realities.

GROWING POINT

The data provide support for continued and perhaps increased involvement of resident in orthopedic surgery.

AREAS OF RESEARCH

To clarify the role of residents on clinically relevant outcomes in orthopedic patients, appropriately powered randomized control trials should be planned.

Is There an Influence of Surgeon's Experience on the Clinical Course in Patients With a Proximal Femoral Fracture?

OBJECTIVES

Teaching of surgical procedures is of paramount importance. However, it can affect patients outcome. The aim of this study was to evaluate if teaching of hip fracture surgery is an independent predictor for negative in-hospital outcome.

DESIGN AND SETTING

Retrospectively, we analyzed all hip fracture patients between 2008 and 2013 recorded in a national quality measurement database (AQC). Inclusion criteria were proximal femoral fracture (ICD-10 diagnostic codes S72.00-S72.11), surgical care of those fracture and a documented teaching status of the intervention. Variables were sought in bivariate and multivariate analyses. Teaching status was entered in multiple regression analysis models for in-hospital death, complications and length of stay while controlling for confounders.

PARTICIPANTS

In the 6-year study period, a total of 4397 patients at a mean age of 80 years met the inclusion criteria. Totally, 48% (n = 2107) of the procedures were conducted as teaching interventions. The rest of our examined cases (n = 2290) were conducted as nonteaching procedures.

RESULTS

There was no association between teaching and mortality, but complications (odds ratio = 1.3; 95% CI: 1.04-1.5; p = 0.018) and prolonged hospitalization (standardized beta = 0.045, p = 0.002) were more likely to occur in the teaching group while controlling for confounders.

CONCLUSIONS

There appears to be no effect of the educational status on the in-hospital death in patients with a proximal femoral fracture. However, teaching was an independent predictor of complications and longer length of stay. Although the differences were significant, the clinical outcome was comparable in both groups, thus justifying the benefits of resident teaching.

Quantification of Resident Work in Colorectal Surgery

OBJECTIVE

To examine resident intraoperative participation, perceived autonomy, and communication patterns between residents and attending surgeons using a novel survey tool.

DESIGN

This was a prospective multi-institutional study. Operative residents completed the survey tool immediately after each colorectal resection performed during the study period. Resident intraoperative participation was quantified including degree of involvement in the technical aspects of the case, self-perception of autonomy, and communication strategies between the resident and attending.

SETTING

This study was conducted at 7 general surgery residency programs: 5 academic medical centers, and 2 independent training programs.

PARTICIPANTS

Residents and fellows rotating on a colorectal surgery service or general surgery service.

RESULTS

Sixty-three residents participated in this study with 417 surveys completed (range 19-79 per institution) representing a 95.4% response rate across all sites. Respondents ranged from clinical year 1 (CY1) to fellows. CY3s (35.7%) and CY5s (34.7%) were most heavily represented. Residents completed ≥50% of the skin closure in 88.7% of cases, ≥50% of the fascial closure in 87.1%, and t ≥ 50% of the anastomosis in 78.4% of the cases. Increasing resident participation was associated with advancing resident CY across all technical aspects of the case. This trend remained significant when controlling for site (p < 0.001). Resident self-perception of autonomy revealed learners of all stages: Observer (11.5%, n = 48), Assistant (53.7%, n = 224), Surgeon (33.8%, n = 141), and Teacher (0.96%, n = 4). Level of perceived autonomy increased with resident CY when controlling for site (p < 0.001). Residents who discussed the case before the day of surgery were twice as likely to rate themselves as Surgeon or Teacher (OR = 2.01) when controlling for CY (p = 0.011).

CONCLUSIONS

Brief surveys can easily capture resident work in the operating room. Resident intraoperative involvement and perceived autonomy are associated with CY. Early communication with the attending is significantly associated with increased perception of autonomy regardless of CY.

Involvement of Residents Does Not Increase Postoperative Complications After Open Reduction Internal Fixation of Ankle Fractures: An Analysis of 3251 Cases

Ankle fractures are common injuries frequently treated by foot and ankle surgeons. Therefore, it has become a core competency for orthopedic residency training. Surgical educators must balance the task of training residents with optimizing patient outcomes and minimizing morbidity and mortality. The present study aimed to determine the effect of resident involvement on the 30-day postoperative complication rates after open reduction and internal fixation of ankle fractures. A second objective of the present study was to determine the independent risk factors for complications after this procedure. We identified patients in the American College of Surgeons National Surgical Quality Improvement Program database who had undergone open reduction internal fixation for ankle fractures from 2005 to 2012. Propensity score matching was used to help account for a potential selection bias. We performed univariate and multivariate analyses to identify the independent risk factors associated with short-term postoperative complications. A total of 3251 open reduction internal fixation procedures for ankle fractures were identified, of which 959 (29.4%) had resident involvement. Univariate (2.82% versus 4.54%; p = .024) and multivariate (odds ratio 0.71; p = .75) analyses demonstrated that resident involvement did not increase short-term complication rates. The independent risk factors for complications after open reduction internal fixation of ankle fractures included insulin-dependent diabetes, increasing age, higher American Society of Anesthesiologists score, and longer operative times.

Tutorial Assistance for Board Certification in Surgery: Frequency, Associated Time and Cost

BACKGROUND

Tutorial assistance is related to extra time and cost, and the hospitals' financial compensation for this activity is under debate. We therefore aimed at quantifying the extra time and resulting cost required to train one surgical resident in the operating theatre for board certification in Switzerland as an example of a training curriculum involving several surgical subspecialties. Additionally, we intended to quantify the percentage of tutorial assistance.

METHODS

We analysed 200,700 operations carried out between 2008 and 2012. Median duration of procedure categories was calculated according to four different seniority levels. The extra time if the procedure was performed by residents, and resulting cost were analysed. The percentage of procedures carried out by residents as compared to more experienced surgeons was assessed over time.

RESULTS

On average, residents performed about a third of all operations including typical teaching procedures like appendectomies. An increase in duration and cost of well-defined procedures categories, e.g. cholecystectomies was demonstrated if a resident performed the procedure. In less well-defined categories, residents seemed to perform less difficult procedures than senior consultants resulting in shorter durations of surgery.

CONCLUSIONS

The financial impact of tutorial assistance is important, and solutions need to be found to compensate for this activity. The low percentage of procedures performed by trainees may make it difficult to fulfil requirements for board certification within a reasonable period of time. This should be addressed within the training curriculum.

Use of Risk Model for Assessment of Residents' Perception of Complexity of Surgical Steps: Example of Modular Component Steps of Lumbar Spinal Fusion Surgery

BACKGROUND

Quality improvement projects increasingly emphasize standardization of surgical work flow to optimize operative room efficiency. Removing special cause variability resulting from nonsurgical waste is an obvious target; however, resident surgical education must be maintained, even in the setting of process improvement.

OBJECTIVE

To describe the impact of resident-identified "risky" or "uncomfortable" procedural steps on operative time during transforaminal lumbar interbody fusion (TLIF).

METHODS

TLIF procedure steps were defined. An 8 2-part questions survey regarding comfort level and perceived risk assessment at each step was developed and completed by junior (17) and senior residents (10), and by faculty (6) from orthopedic, and neurological surgery. A risk matrix was constructed defining 2 zones: a "danger zone"; responses were high risk (3-5) and low comfort (1-3), and a "safe zone"; responses were low risk (1-2) and high comfort (4-5). One-tailed Chi-square with Yates correction was performed.

RESULTS

Risk matrix analysis showed a statistical difference among "danger zone" respondents between junior resident and faculty groups for exposure, pedicle screw placement, neural decompression, interbody placement, posterolateral fusion, and hemostasis. A radar graph identifies percent of respondents who fall within the "danger zone".

CONCLUSION

Resident perception of surgical complexity can be evaluated for procedural steps using a risk matrix survey. For TLIF, residents may assign more risk and may be less comfortable performing steps in a training-level-dependent manner. Identification of particular high-risk or uncomfortable steps should prompt strict faculty oversight to improve patient safety, monitor resident education, and reduce operative time.

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

Importance

In some centers, the presence of a senior general surgeon (SGS) is obligatory in every procedure, including appendectomy, while in others it is not. There is a relative paucity in the literature of reports comparing the outcomes of appendectomies performed by unsupervised general surgery residents (GSRs) with those performed in the presence of an SGS.

Objective

To compare the outcomes of appendectomies performed by SGSs with those performed by GSRs.

Design, Setting, and Participants

A retrospective analysis was performed of all patients 16 years or older operated on for assumed acute appendicitis between January 1, 2008, and December 31, 2015. The cohort study compared appendectomies performed by SGSs and GSRs in the general surgical department of a teaching hospital.

Main Outcomes and Measures

The primary outcome measured was the postoperative early and late complication rates. Secondary outcomes included time from emergency department to operating room, length of surgery, surgical technique (open or laparoscopic), use of laparoscopic staplers, and overall duration of postoperative antibiotic treatment.

Results

Among 1649 appendectomy procedures (mean [SD] patient age, 33.7 [13.3] years; 612 female [37.1%]), 1101 were performed by SGSs and 548 by GSRs. Analysis demonstrated no significant difference between the SGS group and the GSR group in overall postoperative early and late complication rates, the use of imaging techniques, time from emergency department to operating room, percentage of complicated appendicitis, postoperative length of hospital stay, and overall duration of postoperative antibiotic treatment. However, length of surgery was significantly shorter in the SGS group than in the GSR group (mean [SD], 39.9 [20.9] vs 48.6 [20.2] minutes; P < .001).

Conclusions and Relevance

This study demonstrates that unsupervised surgical residents may safely perform appendectomies, with no difference in postoperative early and late complication rates compared with those performed in the presence of an SGS.

Transumbilical laparoscopic appendectomy performed by residents is safe and feasible

INTRODUCTION

The aim of this study was to compare the clinical outcomes of single-incision transumbilical laparoscopy-assisted appendectomy performed by surgical residents and attending surgeons.

METHODS

We reviewed the clinical outcomes of 131 transumbilical laparoscopy-assisted appendectomies performed from January 2011 to June 2014. During the study period, 13 residents and 6 board-certified attending surgeons performed the procedures. For all operations performed by residents and attending surgeons, we reviewed and compared gender, age, BMI, body temperature, white blood cell count, C-reactive protein serum level, and the presence of a fecalith or abscess. Clinical outcomes including operative time, estimated blood loss, need for additional ports, conversion to open surgery, intraoperative complications, postoperative complications, and postoperative hospital stay were compared between the two groups.

RESULTS

The mean preoperative white blood cell count in the resident-operated group was significantly higher than in the attending-operated group (14.0 vs 10.8 ×10³ /mm³ , P = 0.007). There were no other significant differences in clinical variables between the two groups. Outcomes show that estimated blood loss was significantly higher (23.4 vs 9.8 mL, P = 0.031) and operative time tended to be longer (86.0 vs 72.0 min, P = 0.056) in the resident-operated group. No other significant differences were observed.

CONCLUSION

Transumbilical laparoscopy-assisted appendectomy performed by residents is feasible and safe. It is an acceptable as a part of routine surgical training.

Clinical strategies to aim an adequate safety profile for patients and effective training for surgical residents: The laparoscopic cholecystectomy model

Background

Training programs for resident surgeons represent a challenge for the mentoring activity. The aim of the present study is to investigate the impact of our training program for laparoscopic cholecystectomy on patient's safety and on the modulation of the residents' exposure to clinical scenario with different grades of complexity.

Material and methods

This is a retrospective study based on a clinical series of laparoscopic cholecystectomy performed in a teaching hospital. Study population was grouped according to the expertise of the attending primary operator among resident surgeons. Four groups were identified: consultant (C), senior resident (SR); intermediate level resident (IR); junior resident (JR). The intraoperative and postoperative outcomes were confronted to evaluate the patient's safety profile.

Results

447 patients were submitted to LC: 96 cases were operated by a C, 200 by SR, 112 by IR and 39 by JR. The mean operative time was the longest for the JR group. A statistically higher rate of conversion to open approach was registered in C and IR groups in comparison to JR and SR groups. However, in C and IR groups, patients had worse ASA score, higher BMI and more frequent past history of previous abdominal surgery, cholecystitis or pancreatitis. Overall, it was not registered any statistically significant difference among the groups in terms of length of hospital stay and prevalence of major postoperative complications.

Conclusion

Applying an educational model based on both graduated levels of responsibility and modulated grade of clinical complexity can guarantee an high safety profile.

•

Practical training is an essential part in postgraduate programs for Residents.

•

Laparoscopy represents a challenging procedure in terms of mentoring.

•

Our Program seems to be economically sustainable and clinically feasible.

Effect of Residents on Operative Time and Complications: Focus on Laparoscopic Cholecystectomy in the Community

OBJECTIVE

To better understand important aspects of resident education in the perioperative setting, given that there are conflicting data regarding resident training and outcomes (e.g., operative times and complications). To study continuity of care in a resident-run outpatient hospital clinic.

DESIGN

Retrospective analysis of 2 databases.

SETTING

The study was set up in a community teaching hospital.

RESULTS

Of 4603 cases in a cholecystectomy database, 3302 (72%) were assisted by residents, with operative times ranging from 19 to 383 minutes, and 1576 (22.9%) were assisted by nonresidents. The average times were 93 and 77 minutes for resident- and non-resident-assisted cases, respectively. Complications were almost 3 times more likely for urgent vs. elective but were similar for resident-assisted vs. non-resident-assisted cases. The operative time was similar across PGY levels. Of 149 cases in a resident-run outpatient clinic, 100 (67%) of the residents participated in preoperative, intraoperative, and postoperative phases of case, but in only 4% of cases was it the same resident.

CONCLUSION

Resident assistance increased operative times but not complications. Counterbalanced effects of increasing skill and increasing participation may explain this time stability across PGY levels. Continuity of care is preserved in the era of the 80-hour workweek, but not to a patient-specific degree.

Comparative Outcomes of Resident vs Attending Performed Surgery: A Systematic Review and Meta-Analysis

OBJECTIVE

To determine whether outcomes are different when surgery is performed by resident or attending surgeons, and which variables may affect outcomes.

DESIGN

MEDLINE, EMBASE, and the Cochrane Library were searched from inception to May 2014 alongside the bibliographies of all included or relevant studies. Any study comparing outcomes from surgery performed by resident vs attending surgeons was eligible for inclusion. The main outcome measures were surgical complications (classified by Clavien-Dindo grade), death, operative time, and length of stay. Data were extracted independently by 2 authors and analyzed using the random-effects model.

RESULTS

The final analysis included 182 eligible studies that enrolled 141 555 patients. Resident performed surgery took longer by 10.2 minutes (95% confidence interval (CI): 8.38-11.95), and had more Clavien-Dindo grade 1 (rate ratio = 1.14, 95% CI: 1.02-1.29) and grade 3a complications (rate ratio = 1.22, 95% CI: 1.04-1.44). Resident performed surgery resulted in fewer deaths (risk ratio = 0.83, 95% CI: 0.70-0.999) with a shorter length of stay of -0.49 days (95% CI: -0.77 to -0.21). Significant heterogeneity was present in 7 of 10 outcomes, which persisted during multiple subgroup analyses.

CONCLUSIONS

Resident performed surgery appears to be safe in carefully selected patients. The significant amount of heterogeneity present in the study outcomes prevents generalizability of these results to specific clinical contexts.

Financial Contribution of Residents When Billing as "Junior Associates" in the "Surgical Firm"

OBJECTIVE

There is an increasing number of proposals to change the way Graduate Medical Education is funded. This study attempts to estimate the potential financial contribution of surgical residents using an alternative funding mechanism similar to that used by law firms, which would allow surgery departments to bill for resident activity as "junior associates."

METHODS

Following 24 residents over a period of 12 weeks, we were able to estimate the annual revenue that they generated from operating room procedures, independent consultations, patient management, and minor procedures using Medicare reimbursement rates. The appropriate first assistant modifier was used to calculate the operating room procedure fees, but full price was used to calculate the revenue for minor procedures, patient management, and consultations done independently. We adjusted for vacation time and academic activities.

RESULTS

Including postgraduate year 1 residents, the estimated yearly revenue generated per resident in first assistant operative services was $33,305.67. For minor procedures, patient management, and independent consultations, the estimated yearly revenue per resident was $37,350.66. The total estimated financial contribution per resident per year was $70,656.33. Excluding postgraduate year 1 residents, as most states require completion of the intern year before full licensure, the estimated yearly revenue generated per resident in first assistant operative services was $38,914.56. For minor procedures, patient management, and independent consultations, the estimated yearly revenue per resident was $55,957.33. The total estimated financial contribution per resident per year was $94,871.89.

CONCLUSIONS

Residents provide a significant service to hospitals. If resident activity was compensated at the level of supervised "junior associates" of a surgery department, more than 75% of the direct educational costs of training could be offset. Furthermore, we believe this value is underestimated. Given the foreseeable changes in Graduate Medical Education funding, it is imperative that alternative approaches for funding be explored.

Bariatric outcomes are significantly improved in hospitals with fellowship council-accredited bariatric fellowships

BACKGROUND

With the increasing demand of bariatric surgery, there is a need to train more surgeons, while identifying institutional factors associated with improved outcomes. Little is known regarding the impact of a fellowship training program on institutional outcomes. This study examines the effect of bariatric fellowship program status on perioperative outcomes within New York state.

METHODS

Using the New York statewide planning and research cooperative system, 47,342 adult patients in 91 hospitals were identified who underwent a laparoscopic bariatric surgery over a 6-year period. Hospitals with fellowships were identified from the Fellowship Council. Statistical comparison between patient demographics, payer source, comorbidities, bariatric procedure performed, and perioperative outcomes in hospitals with and without fellowship were performed.

RESULTS

On univariate analysis, fellowship accreditation status was found to be associated with increased rates of cardiac complications and shock and decreased rates of pneumonia. Overall complication rate was not significantly different in fellowship versus non-fellowship institutions. However, when controlled for patient demographic, payer source, comorbidity, and operative procedure, there were significantly improved bariatric outcomes among institutions with fellowship programs.

CONCLUSIONS

The presence of a fellowship program correlates with improved hospital outcomes, mitigating potential concerns about possible negative effects of trainees on hospitals and patients.

The costs of operative complications for ankle fractures: a case control study

As our healthcare system moves towards bundling payments, it is vital to understand the potential financial implications associated with treatment of surgical complications. Considering that surgical treatment of ankle fractures is common, there remains minimal data relating costs to postsurgical intervention. We aimed to identify costs associated with ankle fracture complications through case-control analysis. Using retrospective analysis at a level I trauma center, 28 patients with isolated ankle fractures who developed complications (cases) were matched with 28 isolated ankle fracture patients without complications (controls) based on ASA score, age, surgery type, and fracture type. Patient charts were reviewed for demographics and complications leading to readmission/reoperation and costs were obtained from the financial department. Wilcoxon tests measured differences in the costs between the cases and controls. 28 out of 439 patients (6.4%) developed complications. Length of stay and median costs were significantly higher for cases than controls. Specifically, differences in total costs existed for infection and hardware-related pain. This is the first study to highlight the considerable costs associated with the treatment of complications due to isolated ankle fractures. Physicians must therefore emphasize methods to control surgical and nonsurgical factors that may impact postoperative complications, especially under a global payment system.

Outcomes associated with resident involvement in laparoscopic colorectal surgery suggest a need for earlier and more intensive resident training

PURPOSE

The aim of this study is to determine if resident involvement in a large cohort of laparoscopic colorectal surgery (LCS) cases negatively impacts outcomes and ultimately increases costs.

METHODS

The American College of Surgeons National Surgical Quality Improvement Program database was queried for patients who underwent LCS between 2005 and 2010. Patients were classified into two groups: postgraduate year (PGY; resident involvement) or Attending Only. A subgroup analysis was then conducted among the individual PGY levels (1-2, 3-5, ≥6) and Attending Only group.

RESULTS

A total of 4,836 patients were included in the PGY group and 2,418 in the Attending Only group. Mean operative time (163.9 ± 66.7 vs. 140.7 ± 67.2 minutes, P < .001) and length of hospital stay (5.8 ± 5.4 vs. 5.6 ± 5.4 days, P = .015) were significantly longer in the PGY group. Surgical and nonsurgical complications and overall morbidity and mortality rates were similar between the two groups. Each individual PGY group was associated with longer operative time (P < .001), and PGY ≥ 6 was associated with an increased length of stay (P < .001).

CONCLUSION

Although resident participation in LCS does not affect overall mortality or morbidity, it may negatively impact hospital costs through increased operative time and length of hospital stay. Early and intensive laparoscopy training may be necessary for improving residents' laparoscopy skills before their involvement in LCS.

Resident involvement does not influence complication after total hip arthroplasty: an analysis of 13,109 cases

Our study aimed to determine the impact of resident involvement on the 30-day postoperative complication rates following primary total hip arthroplasty (THA). Using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database, 13,109 primary THAs were identified, of which 3462 (26.4%) had resident involvement. Neither univariate (4.45% vs 4.52%, P = 0.86) nor multivariate (OR 1.04, P = 0.75) analyses demonstrated an increased complication rate with resident involvement following THA. We did find, however, that increased operative time, comorbidities, age, obesity, prior history of stroke and/or cardiac surgery were all independent risk factors for short-term complication. Our findings suggest that resident involvement does not increase 30-day complication rates following primary THA.

Does resident involvement impact post-operative complications following primary total knee arthroplasty? An analysis of 24,529 cases

Little is known about the impact of resident involvement on complication rates following total knee arthroplasty (TKA). The goal of our study was to determine the impact of resident involvement on complications following primary TKA. Using the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database (2005-2012) we identified 24,529 patients who underwent primary TKA. Of these, 5960 (24.3%) had a resident involved in a primary TKA. Using a multivariate logistic regression which incorporated propensity score adjustment, no differences were seen in morbidity and mortality following those cases with resident involvement (OR: 1.15, P = 0.129). In the first large scale, comprehensive analysis of resident impact on short-term morbidity and mortality, no increase in complications was observed with resident involvement in primary TKA.

Safety assessment of resident grade and supervision level during emergency appendectomy: analysis of a multicenter, prospective study

BACKGROUND

Resident surgeons have been identified as a risk factor for worse outcome after appendectomy. The context of grade of resident and impact of supervision require further investigation. The objective of this study was to determine whether grade and supervision level of resident-performed appendectomy affects patient outcome.

METHODS

A multicenter, prospective cohort study was performed for consecutive patients undergoing appendectomy during May and June 2013. The primary endpoint for this analysis was the 30-day adverse event rate. Supervision was defined as resident-performed appendectomy with an attending scrubbed. Multivariable binary logistic regression was used to take into account case mix and produce adjusted odds ratios (OR).

RESULTS

From 2,867 appendectomies, 87% were performed by residents, and 72% were performed unsupervised. Residents operated on significantly younger patients with lower American Society of Anesthesiologists scores. Although wound infection rates were similar between attendings, and senior and junior residents (4.1%, 3.8%, 3.4% respectively; P = .486), pelvic abscess rate was greater for attendings (5.2%, 2.7%, 2.4%; P = .045). In adjusted models, supervised senior, supervised junior, and unsupervised junior residents showed no difference in 30-day adverse event rates compared with attendings (OR, 1.07 [P = .834], 0.93 [P = .773], and 0.83 [P = .264] respectively); unsupervised senior residents had a lesser rate of adverse events (OR, 0.71; P = .045). All resident groups showed no difference for rates of histopathologically normal appendectomy compared with attendings.

CONCLUSION

Resident-performed appendectomy does not worsen patient outcomes. These findings support independent resident operating rights for selected cases. The system relies on mutual credentialing of competency between residents and supervising attendings.

Adrenalectomy outcomes are superior with the participation of residents and fellows

BACKGROUND

Adrenalectomy is a complex procedure performed in many settings, with and without residents and fellows. Patients often ask, "Will trainees be participating in my operation?" and seek reassurance that their care will not be adversely affected. The purpose of this study was to determine the association between trainee participation and adrenalectomy perioperative outcomes.

STUDY DESIGN

We performed a cohort study of patients who underwent adrenalectomy from the 2005 to 2011 American College of Surgeons NSQIP database. Trainee participation was classified as none, resident, or fellow, based on postgraduate year of the assisting surgeon. Associations between trainee participation and outcomes were determined via multivariate linear and logistic regression.

RESULTS

Of 3,694 adrenalectomies, 732 (19.8%) were performed by an attending surgeon with no trainee, 2,315 (62.7%) involved a resident, and 647 (17.5%) involved a fellow. The participation of fellows was associated with fewer serious complications (7.9% with no trainee, 6.0% with residents, and 2.8% with fellows; p < 0.001). In a multivariate model, the odds of serious 30-day morbidity were lower when attending surgeons operated with residents (odds ratio = 0.63; 95% CI, 0.45-0.89). Fellow participation was associated with significantly lower odds of overall (odds ratio = 0.51; 95% CI, 0.32-0.82) and serious (odds ratio = 0.31; 95% CI, 0.17-0.57) morbidity. There was no significant association between trainee participation and 30-day mortality.

CONCLUSIONS

In this analysis of multi-institutional data, the participation of residents and fellows was associated with decreased odds of perioperative adrenalectomy complications. Attending surgeons performing adrenalectomies with trainee assistance should reassure patients of the equivalent or superior care they are receiving.

Does resident experience affect outcomes in complex abdominal surgery? Pancreaticoduodenectomy as an example

OBJECTIVES

Understanding the factors contributing to improved postoperative patient outcomes remains paramount. For complex abdominal operations such as pancreaticoduodenectomy (PD), the influence of provider and hospital volume on surgical outcomes has been described. The impact of resident experience is less well understood.

METHODS

We reviewed perioperative outcomes after PD at a single high-volume center between 2006 and 2012. Resident participation and outcomes were collected in a prospectively maintained database. Resident experience was defined as postgraduate year (PGY) and number of PDs performed.

RESULTS

Forty-three residents and four attending surgeons completed 686 PDs. The overall complication rate was 44 %; PD-specific complications (defined as pancreatic fistula, delayed gastric emptying, intraabdominal abscess, wound infection, and bile leak) occurred in 28 % of patients. The overall complication rates were similar when comparing PGY 4 to PGY 5 residents (55.3 vs. 43.0 %; p > 0.05). On univariate analysis, there was a difference in PD-specific complications seen between a PGY 4 as compared to a PGY 5 resident (44 vs. 27 %, respectively; p = 0.016). However, this was not statistically significant when adjusted for attending surgeon. Logistic regression demonstrated that as residents perform more cases, PD-specific complications decrease (OR = 0.97; p < 0.01). For a resident's first PD case, the predicted probability of a PD-specific complication is 27 %; this rate decreases to 19 % by resident case number 15.

CONCLUSIONS

Complex cases, such as PD, provide unparalleled learning opportunities and remain an important component of surgical training. We highlight the impact of resident involvement in complex abdominal operations, demonstrating for the first time that as residents build experience with PD, patient outcomes improve. This is consistent with volume-outcome relationships for attending physicians and high-volume hospitals. Maximizing resident repetitive exposure to complex procedures benefits both the patient and the trainee.

Impact of tutorial assistance in laparoscopic sigmoidectomy for acute recurrent diverticulitis

PURPOSE

Adequate training and close supervision by an experienced surgeon are crucial to assure the patient safety during laparoscopic training. This study evaluated the impact of tutorial assistance on the duration of surgery and postoperative complications after laparoscopic sigmoidectomy.

METHODS

The data from 235 patients undergoing laparoscopic sigmoidectomy were collected. Operating surgeons were classified as either residents/registrars (group A, tutorial assistance) or consultants operating autonomously (group B). Groups were compared concerning the duration of surgery and in-hospital complications using a multivariable regression model accounting for the most relevant confounders.

RESULTS

The median duration of the operation in group A (n = 75) was 221 min, and that in group B (n = 160) 189 min (p < 0.001). The risk of developing any in-hospital complication (Clavien-Dindo classification I-V) was 36.0 % in Group A and 32.5 % in group B (95 % CI -16.6, 9.6 %). The risk of developing moderate to severe surgical complications (Clavien-Dindo classification II-V) was 16.0 % in group A and 12.5 % in group B (95 % CI -13.3, 6.3 %).

CONCLUSIONS

We were unable to demonstrate a clear impact of tutorial assistance on the risk of postoperative complications. Although associated with a longer duration of surgery, laparoscopic sigmoidectomy for acute recurrent sigmoid diverticulitis conducted by a junior supervised surgeon appears to be a safe surgical modality.
