Development and preliminary validation of a new task-based objective procedure-specific assessment of inguinal hernia repair procedural safety.

BACKGROUND: Surgical videos coupled with structured assessments enable surgical training programs to provide independent competency evaluations and align with the American Board of Surgery's entrustable professional activities initiative. Existing assessment instruments for minimally invasive inguinal hernia repair (IHR) have limitations with regards to reliability, validity, and usability. A cross-sectional study of six surgeons using a novel objective, procedure-specific, 8-item competency assessment for minimally invasive inguinal hernia repair (IHR-OPSA) was performed to assess inter-rater reliability using a "safe" vs. "unsafe" scoring rubric. METHODS: The IHR-OPSA was developed by three expert IHR surgeons, field tested with five IHR surgeons, and revised based upon feedback. The final instrument included: (1) incision/port placement; (2) dissection of peritoneal flap (TAPP) or dissection of peritoneal flap (TEP); (3) exposure; (4) reducing the sac; (5) full dissection of the myopectineal orifice; (6) mesh insertion; (7) mesh fixation; and (8) operation flow. The IHR-OPSA was applied by six expert IHR surgeons to 20 IHR surgical videos selected to include a spectrum of hernia procedures (15 laparoscopic, 5 robotic), anatomy (14 indirect, 5 direct, 1 femoral), and Global Case Difficulty (easy, average, hard). Inter-rater reliability was assessed against Gwet's AC2. RESULTS: The IHR-OPSA inter-rater reliability was good to excellent, ranging from 0.65 to 0.97 across the eight items. Assessments of robotic procedures had higher reliability with near perfect agreement for 7 of 8 items. In general, assessments of easier cases had higher levels of agreement than harder cases. CONCLUSIONS: A novel 8-item minimally invasive IHR assessment tool was developed and tested for inter-rater reliability using a "safe" vs. "unsafe" rating system with promising results. To promote instrument validity the IHR-OPSA was designed and evaluated within the context of intended use with iterative engagement with experts and testing of constructs against real-world operative videos.

A multi-national, video-based qualitative study to refine training guidelines for assigning an "unsafe" score in laparoscopic cholecystectomy critical view of safety.

BACKGROUND: The critical view of safety (CVS) was incorporated into a novel 6-item objective procedure-specific assessment for laparoscopic cholecystectomy (LC-CVS OPSA) to enhance focus on safe completion of surgical tasks and advance the American Board of Surgery's entrustable professional activities (EPAs) initiative. To enhance instrument development, a feasibility study was performed to elucidate expert surgeon perspectives regarding "safe" vs. "unsafe" practice. METHODS: A multi-national consortium of 11 expert LC surgeons were asked to apply the LC-CVS OPSA to ten LC videos of varying surgical difficulty using a "safe" vs. "unsafe" scale. Raters were asked to provide written rationale for all "unsafe" ratings and invited to provide additional feedback regarding instrument clarity. A qualitative analysis was performed on written responses to extract major themes. RESULTS: Of the 660 ratings, 238 were scored as "unsafe" with substantial variation in distribution across tasks and raters. Analysis of the comments revealed three major categories of "unsafe" ratings: (a) inability to achieve the critical view of safety (intended outcome), (b) safe task completion but less than optimal surgical technique, and (c) safe task completion but risk for potential future complication. Analysis of reviewer comments also identified the potential for safe surgical practice even when CVS was not achieved, either due to unusual anatomy or severe pathology preventing safe visualization. Based upon findings, modifications to the instructions to raters for the LC-CVS OPSA were incorporated to enhance instrument reliability. CONCLUSIONS: A safety-based LC-CVS OPSA has the potential to significantly improve surgical training by incorporating CVS formally into learner assessment. This study documents the perspectives of expert biliary tract surgeons regarding clear identification and documentation of unsafe surgical practice for LC-CVS and enables the development of training materials to improve instrument reliability. Learnings from the study have been incorporated into rater instructions to enhance instrument reliability.

Laparoscopic cholecystectomy critical view of safety (LC-CVS): a multi-national validation study of an objective, procedure-specific assessment using video-based assessment (VBA).

BACKGROUND: A novel 6-item objective, procedure-specific assessment for laparoscopic cholecystectomy incorporating the critical view of safety (LC-CVS OPSA) was developed to support trainee formative and summative assessments. The LC-CVS OPSA included two retraction items (fundus and infundibulum retraction) and four CVS items (hepatocystic triangle visualization, gallbladder-liver separation, cystic artery identification, and cystic duct identification). The scoring rubric for retraction consisted of poor (frequently outside of defined range), adequate (minimally outside of defined range) and excellent (consistently inside defined range) and for CVS items were "poor-unsafe", "adequate-safe", or "excellent-safe". METHODS: A multi-national consortium of 12 expert LC surgeons applied the OPSA-LC CVS to 35 unique LC videos and one duplicate video. Primary outcome measure was inter-rater reliability as measured by Gwet's AC2, a weighted measure that adjusts for scales with high probability of random agreement. Analysis of the inter-rater reliability was conducted on a collapsed dichotomous scoring rubric of "poor-unsafe" vs. "adequate/excellent-safe". RESULTS: Inter-rater reliability was high for all six items ranging from 0.76 (hepatocystic triangle visualization) to 0.86 (cystic duct identification). Intra-rater reliability for the single duplicate video was substantially higher across the six items ranging from 0.91 to 1.00. CONCLUSIONS: The novel 6-item OPSA LC CVS demonstrated high inter-rater reliability when tested with a multi-national consortium of LC expert surgeons. This brief instrument focused on safe surgical practice was designed to support the implementation of entrustable professional activities into busy surgical training programs. Instrument use coupled with video-based assessments creates novel datasets with the potential for artificial intelligence development including computer vision to drive assessment automation.

Using video-based assessment (VBA) to document fellow improvement in safely completing the jejunojejunostomy portion of laparoscopic Roux-en-Y gastric bypass (RYGB) surgery.

BACKGROUND: Surgical assessment instruments are used for formative and summative trainee evaluations. To characterize the features of existing instruments and a novel 12-item objective, procedure-specific assessment tool for Roux-en-Y Gastric Bypass (RYGB-OPSA), we evaluated the progress of a single surgical fellow over 17 consecutive surgeries. METHODS: Seventeen consecutive RYGB videos completed between 8/2021 and 1/2022 by an academic hospital surgical fellow were de-identified and assessed by four board-certified bariatric surgeons using Global Operative Assessment of Laparoscopic Skills (GOALS), General Assessment of Surgical Skill (GASS), and RYGB-OPSA which includes the reflection of transverse colon, identification of ligament of Treitz, biliopancreatic and Roux limbs orientation, jejunal division point selection, stapler use, mesentery division, bleeding control, jejunojejunostomy (JJ) anastomotic site selection, apposition of JJ anastomotic site, JJ creation, common enterotomy closure of JJ, and integrity of anastomosis. The GASS measured economy of motion, tissue handling, appreciating operative anatomy, bimanual dexterity, and achievement of hemostasis. RYGB-OPSA and GASS items were scored "poor-unsafe," "acceptable-safe," or "good-safe." Change in performance was measured by linear trendline slope. RESULTS: Over the course of 17 procedures, significant improvement was demonstrated by three GOALS items, GOALS overall score, GASS bimanual dexterity, and three RYGB-OPSA tasks: JJ creation, jejunal division point selection, and stapler use. Achievement of hemostasis declined but never rated "poor-unsafe." Overall RYGB-OPSA and GOALS trendlines documented significant increase across the 17 procedures. CONCLUSION: This examination of a bariatric surgery fellow's operative training experience as measured by three surgical assessment instruments demonstrated anticipated improvements in general skills and safe completion of procedure-specific tasks. Effective surgical assessment instruments have enough sensitivity to show improvement to enable meaningful trainee feedback (low-stakes assessments) as well as the ability to determine safe surgical practice to enable promotion to greater autonomous practice.

A Practical Approach to Predicting Surgical Site Infection Risk Among Patients Before Leaving the Operating Room.

A surgical site infection (SSI) prediction model that identifies at-risk patients before leaving the operating room can support efforts to improve patient safety. In this study, eight pre-operative and five perioperative patient- and procedure-specific characteristics were tested with two scoring algorithms: 1) count of positive factors (manual), and 2) logistic regression model (automated). Models were developed and validated using data from 3,440 general and oncologic surgical patients. In the automated algorithm, two pre-operative (procedure urgency, odds ratio [OR]: 1.7; and antibiotic administration >2 hours before incision, OR: 1.6) and three intraoperative risk factors (open surgery [OR: 3.7], high-risk procedure [OR: 3.5], and operative time OR: [2.6]) were associated with SSI risk. The manual score achieved an area under the curve (AUC) of 0.831 and the automated algorithm achieved AUC of 0.868. Open surgery had the greatest impact on prediction, followed by procedure risk, operative time, and procedure urgency. At 80% sensitivity, the manual and automated scores achieved a positive predictive value of 16.3% and 22.0%, respectively. Both the manual and automated SSI risk prediction algorithms accurately identified at-risk populations. Use of either model before the patient leaves the operating room can provide the clinical team with evidence-based guidance to consider proactive intervention to prevent SSIs.

Global assessment of surgical skills (GASS): validation of a new instrument to measure global technical safety in surgical procedures.

BACKGROUND: Broad implementation of the American Board of Surgery's entrustable professional activities initiative will require assessment instruments that are reliable and easy to use. Existing assessment instruments of general laparoscopic surgical skills have limited reliability, efficiency, and validity across the spectrum of formative (low-stakes) and summative (high-stakes) assessments. A novel six-item global assessment of surgical skills (GASS) instrument was developed and evaluated with a focus upon safe versus unsafe surgical practice scoring rubric. METHODS: The GASS was developed by iterative engagement with expert laparoscopic surgeons and includes six items (economy of motion, tissue handling, appreciating operative anatomy, bimanual dexterity, achievement of hemostasis, overall performance) with a uniform three-point scoring rubric ("poor-unsafe", "adequate-safe", "good-safe"). To test inter-rater reliability, a cross-sectional study of four bariatric surgeons with experience ranging from 4 to 28 years applied the GASS and the global operative assessment of laparoscopic skills (GOALS) to 30 consecutive Roux-en-Y gastric bypass procedure operative videos. Inter-rater reliability was assessed for a simplified dichotomous "safe" versus "unsafe" scoring rubric using Gwet's AC2. RESULTS: The GASS inter-rater reliability was very high across all six domains (0.88-1.00). The GASS performed comparably to the GOALS inter-rater reliability scores (0.96-1.00). The economy of motion and bimanual dexterity items had the highest percentage of unsafe ratings (9.2% and 5.8%, respectively). CONCLUSION: The GASS, a novel six-item instrument of general laparoscopic surgical skills, was designed with a simple scoring rubric (poor-safe, adequate-safe, good-safe) to minimize rater burden and focus feedback to trainees and promotion evaluations on safe surgical performance. Initial evaluation of the GASS is promising, demonstrating high inter-rater reliability. Future research will seek to assess the GASS against a broader spectrum of laparoscopic procedures.

Hepatobiliary manifestations following two-stages elective laparoscopic restorative proctocolectomy for patients with ulcerative colitis: A prospective observational study.

BACKGROUND: Hepatobiliary manifestations occur in ulcerative colitis (UC) patients. The effect of laparoscopic restorative proctocolectomy (LRP) with ileal pouch anal anastomosis (IPAA) on hepatobiliary manifestations is debated. AIM: To evaluate hepatobiliary changes after two-stages elective laparoscopic restorative proctocolectomy for patients with UC. METHODS: Between June 2013 and June 2018, 167 patients with hepatobiliary symptoms underwent two-stage elective LRP for UC in a prospective observational study. Patients with UC and having at least one hepatobiliary manifestation who underwent LRP with IPAA were included in the study. The patients were followed up for four years to assess the outcomes of hepatobiliary manifestations. RESULTS: The patients' mean age was 36 ± 8 years, and males predominated (67.1%). The most common hepatobiliary diagnostic method was liver biopsy (85.6%), followed by Magnetic resonance cholangiopancreatography (63.5%), Antineutrophil cytoplasmic antibodies (62.5%), abdominal ultrasonography (35.9%), and Endoscopic retrograde cholangiopancreatography (6%). The most common hepatobiliary symptom was Primary sclerosing cholangitis (PSC) (62.3%), followed by fatty liver (16.8%) and gallbladder stone (10.2%). 66.4% of patients showed a stable course after surgery. Progressive or regressive courses occurred in 16.8% of each. Mortality was 6%, and recurrence or progression of symptoms required surgery for 15%. Most PSC patients (87.5%) had a stable course, and only 12.5% became worse. Two-thirds (64.3%) of fatty liver patients showed a regressive course, while one-third (35.7%) showed a stable course. Survival rates were 98.8%, 97%, 95.8%, and 94% at 12 mo, 24 mo, 36 mo, and at the end of the follow-up. CONCLUSION: In patients with UC who had LRP, there is a positive impact on hepatobiliary disease. It caused an improvement in PSC and fatty liver disease. The most prevalent unchanged course was PSC, while the most common improvement was fatty liver disease.

Association between Surgical Technical Skills and Clinical Outcomes: A Systematic Literature Review and Meta-Analysis.

Background: A systematic literature review and meta-analysis was conducted to assess the association between intraoperative surgical skill and clinical outcomes. Methods: Peer-reviewed, original research articles published through August 31, 2021 were identified from PubMed and Embase. From the 1,513 potential articles, seven met eligibility requirements, reporting on 151 surgeons and 17,932 procedures. All included retrospective assessment of operative videos. Associations between surgical skill and outcomes were assessed by pooling odds ratios (OR) using random-effects models with the inverse variance method. Eligible studies included pancreaticoduodenectomy, gastric bypass, laparoscopic gastrectomy, prostatectomy, colorectal, and hemicolectomy procedures. Results: Meta-analytic pooling identified significant associations between the highest vs. lowest quartile of surgical skill and reoperation (OR: 0.44; 95% confidence interval [CI]: 0.23, 0.83), hemorrhage (OR: 0.66; 95% CI, 0.65, 0.68), obstruction (OR: 0.33; 95% CI, 0.30, 0.35), and any medical complication (OR: 0.23, 95% CI, 0.19, 0.27). Nonsignificant inverse associations were noted between skill and readmission, emergency department visit, mortality, leak, infection, venous thromboembolism, and cardiac and pulmonary complications. Conclusions: Overall, surgeon technical skill appears to predict clinical outcomes. However, there are surprisingly few articles that evaluate this association. The authors recommend a thoughtful approach for the development of a comprehensive surgical quality infrastructure that could significantly reduce the challenges identified by this study.

A Pilot Study to Determine the Impact of Adipose Tissue Attachment to Polypropylene Fibers In Hernia Mesh.

INTRODUCTION: Prior publications have demonstrated chemical and physical alteration of hernia mesh analyzed after explantation from the body. The specific alteration documented is oxidative degradation of polypropylene mesh fibers. An animal study recently published has demonstrated that adipose tissue attachment is present instead of reparative fibrous tissue infiltration in an average of 10.9-18.9% of the intramesh healing for a variety of clinically used knitted polypropylene mesh products; 8.0% for knitted polyester meshes. This study also found that in comparison to the knitted mesh products, non-woven polypropylene mesh reduced adipose tissue attachment to 1% or less, which was a statistically significant difference. MATERIALS AND METHODS: Samples of explanted polypropylene mesh from eight patients were analyzed for the presence of adipose tissue attachment, reparative fibrous tissue infiltration, and oxidative changes. Greater adipose tissue attachment areas were compared with areas of greater reparative fibrous tissue infiltration for evidence of oxidative changes in the mesh to determine if the areas of higher adipose tissue attachment correlated with an increase in oxidative changes. RESULTS: Intra mesh healing of clinically explanted knitted meshes demonstrated adipose tissue content from 0.0% to 49.1% per analyzed segment. The oxidation index, a measure of the degree of oxidative degradation in that portion of the mesh, was higher in seven of the eight areas of greater adipose tissue attachment than areas of greater reparative fibrous tissue infiltration. CONCLUSION: Adipose tissue attachment does occur in knitted and woven polypropylene hernia meshes. The presence of adipose tissue may contribute to an increase in oxidative changes in knitted polypropylene hernia mesh fibers.

Applying systems and complexity science to real patient care.

AIMS AND OBJECTIVES: To describe the application of systems and complexity science principles to real patient care. RATIONALE: Our current global health care system is not sustainable. It is structured based on the principles of reductionist science, which was discovered and developed over the past 400 to 600 years. Because of increasing pace of change and increasing complexity in our world, we have increased fragmentation in our health care system leading to more harm and waste. Over 100 years ago, the principles of systems, or complexity, science were discovered, first in the discipline of physics. These principles accommodate the constant change and biologic variability in our world. While reductionist principles would be applicable in a static, mechanical world where parts of the system could be isolated, this does not exist in the real biologic world. METHODS: For the past decade, our abdominal wall hernia team has been applying the principles of systems science to real patient care. Some of the tools we have applied include continuous quality improvement for whole hernia patient processes and non-linear analytical tools to gain insight to improve value-based outcomes. Until we learn to apply and scale these principles across our whole global health care system, we will continue to suffer the consequences of our current unsustainable system. RESULTS: We have learned that the application of systems and complexity science to real patient care can lead to lower costs and better outcomes in the context of patients with complex hernia problems. However, these concepts have not yet been adopted in our global health care system. CONCLUSION: Applying the principles of systems and complexity science to our global health care system has the potential to lower costs and improve patient outcomes for any patient care process to which it is applied.

Improving Shared Decision-making and Treatment Planning Through Predictive Modeling: Clinical Insights on Ventral Hernia Repair.

Abdominal wall hernia repair, including ventral hernia repair, is one of the most common general surgical procedures. Nationally, at least 350 000 ventral hernia repairs are performed annually, and of those, 150 000 cases were identified as incisional hernias. Outcomes are reported to be poor, resulting in additional surgical repair rates of 12.3% at 5 years and as high as 23% at 10 years. Healthcare costs associated with ventral hernia repair are estimated to exceed $3 billion each year. Additionally, ventral hernia repair is often complex and unpredictable when there is a current infection or a history of infection and significant comorbidities. Accordingly, a predictive model was developed using a retrospectively collected dataset to associate the pre- and intra-operative characteristics of patients to their outcomes, with the primary goal of identifying patients at risk of developing complications a priori in the future. The benefits and implications of such a predictive model, however, extend beyond this primary goal. This predictive model can serve as an important tool for clinicians who may use it to support their clinical intuition and clarify patient need for lifestyle modification prior to abdominal wall reconstruction. This predictive model can also support shared decision-making so that a personalized plan of care may be developed. The outcomes associated with use of the predictive model may include surgical repair but may suggest lifestyle modification coupled with less invasive interventions.

Evaluating effectiveness of cognitive behavioral therapy within multimodal treatment for chronic groin pain after inguinal hernia repair.

INTRODUCTION: The development of chronic groin pain after inguinal hernia repair is a complex problem with many potential factors contributing to its development. Surgical options for alleviation of symptoms are limited and only performed by a few centers dedicated to its treatment. Opportunities to apply the principles of a prehabilitation program, including Cognitive Behavioral Therapy (CBT), aim to improve the surgical outcomes for this condition. METHODS AND PROCEDURES: A multi-disciplinary hernia team has implemented a clinical quality improvement (CQI) effort in an attempt to better measure and improve outcomes for patients suffering with chronic groin pain after inguinal hernia repair. Between April 2011 and August 2018, 129 patients (157 groins) underwent surgical treatment for chronic groin pain after inguinal hernia repair. Data were collected to compare outcomes for those undergoing preoperative CBT and patients who did not have CBT prior to their operation. RESULTS: Of 129 total patients, baseline demographics were similar in terms of gender, age, and BMI. In total, 27 patients (32 groins) underwent prehabilitation with CBT (20.93%). We found none of the patients who underwent preoperative CBT had new postoperative pain and all patient procedures were able to be performed on an outpatient basis. Overall, 15 (14.7%) patients had no improvement in symptoms after surgery from the non-CBT group, whereas there was improvement in chronic pain for all patients who underwent CBT. CONCLUSION: This attempt at process improvement demonstrated beneficial effects for patients who had CBT as part of a prehabilitation program prior to a surgical procedure to attempt to relieve groin pain after inguinal hernia repair. As with any CQI analysis, other factors may have contributed to these outcomes and these results may be different in another local environment.

Laparoscopic Ventral Hernia Repair with a Non-Woven Hernia Mesh.

INTRODUCTION: Laparoscopic ventral hernia repair is a commonly performed procedure with a variety of mesh options. A relatively new mesh option is a non-woven polypropylene mesh with a silicone barrier designed for intraabdominal placement. This non-woven randomly oriented polypropylene microfiber hernia mesh may have benefits with potentially better biocompatibility compared with other ventral hernia repair mesh options. MATERIALS AND METHODS: A clinical quality improvement (CQI) program was initiated for ventral hernia patients to better measure and improve outcomes. From March 2013 to September 2015, 62 laparoscopic ventral hernia repairs were performed with this non-woven polypropylene mesh on 61 patients (one patient had two separate hernia repairs). Attempts were made to obtain long-term (> 2 years) follow up. RESULTS: There were 36 females and 25 males. The average age was 58.7 years (range 21-85). The average body mass index (BMI) was 36.2 (range 21.4-62.4). There were 51 (82%) incisional hernias and 11 (18%) primary hernias. There were 29 (47%) recurrent hernias. Mean hernia size was 83.4cm2 (range 1-400) and mean mesh size was 508.5cm2 (range 144-936). The mean operating room (OR) time was 108.2 minutes (range 38-418). The mean length of hospital stay was 2.7 days (range 0-13). There was one intraoperative complication-an injury to an inferior epigastric vessel that had a minor postoperative bleed that was self-limiting and required no treatment. There was one postoperative death due to aspiration on postoperative day #4. There has been one recurrence (1.6%) with long-term follow up. There were two patients (3.2%) with suture site pain postoperatively that resolved with suture site injections of local anesthetic in the clinic. There were no patients that required rehospitalization within 30 days after surgery. There were no mesh-related complications and no incidence of mesh removal was required. CONCLUSION: The results for laparoscopic ventral hernia repair, using a relatively new non-woven randomly oriented polypropylene microfiber mesh, are good with long-term follow up completed in the majority of patients. More experience with this type of mesh could generate evidence for the benefits of this mesh material in laparoscopic ventral hernia repair.

A Cost-Minimization Analysis Evaluating the Use of Liposomal Bupivacaine in Reconstructive Plastic Surgery Procedures.

BACKGROUND: Postsurgical pain management is critical to patient satisfaction and value. Several studies have evaluated liposomal bupivacaine in postoperative pain management protocols; however, its economic feasibility remains undefined. This study analyzes the economic impact of liposomal bupivacaine using a national claims database to assess postoperative clinical and financial outcomes in plastic and reconstructive procedures. METHODS: The Vizient Clinical Data Base/Resource Manager electronic database was reviewed for plastic surgery procedures (i.e., abdominoplasty, abdominal wall reconstruction, mastectomy with immediate tissue expander placement, mastectomy with direct-to-implant reconstruction, autologous breast reconstruction, and augmentation mammaplasty) at participating hospitals from July 1, 2016, to July 1, 2017. The main outcome measures were the length of stay; 7-, 14-, and 30-day readmission rates; and direct and total costs observed. RESULTS: During the study period, 958 total cases met inclusion criteria. Liposomal bupivacaine was used in 239 cases (25 percent). Compared with cases that did not use liposomal bupivacaine, liposomal bupivacaine cases had a decreased length of stay (9.2 days versus 5.8 days), decreased cost (total cost, $39,531 versus $28,021; direct cost, $23,960 versus $17,561), and lower 30-day readmission rates (4 percent versus 0 percent). The 14- and 7-day readmission rates were similar between the two groups. CONCLUSIONS: The use of liposomal bupivacaine may contribute to a reduction in length of stay, hospital costs, and 30-day readmission rates for abdominal and breast reconstructive procedures, which could contribute to a favorable economic profile from a system view. Focusing on the measurement and improvement of value in the context of whole, definable, patient processes will be important as we transition to value-based payments.

Evaluating and Exploring Variations in Surgical Resident Emotional Intelligence and Burnout.

OBJECTIVE: Surgery resident burnout rates are on the rise, ranging from 50% to 69%. Burnout is associated with increased risk of error and poorer patient satisfaction. Emotional intelligence (EI) is defined as the capacity to be aware of, control, and express one's emotions, and to handle interpersonal relationships judiciously and empathetically. We seek to evaluate the correlation between EI and burnout temporally as a potential target for education. This may allow us to utilize objective measures to reduce burnout among our residents. DESIGN: A prospective study of general surgery residents at a single institution was performed via self-reporting assessments on personal demographics, the Maslach Burnout Inventory (MBI), and the Scale of Emotional Functioning: Health Service Provider at 3 separate time-points. SETTING: A medium sized academic medical center in Tennessee approved to graduate 6 chief residents per year. PARTICIPANTS: All general surgery residents PGY1 to PGY5 including preliminary residents were given the assessment tools and the option of participating. Research residents were excluded. RESULTS: A total of 86 assessments were completed, including 15 residents who completed all 3 assessments. Changes in the personal achievement (PA) portion of the MBI had the strongest correlation with temporal changes in EI with a Pearson correlation coefficient of 0.606 and 0.616 (p 0.017 and 0.015, respectively). Of the 3 subscales of the MBI, residents had moderate or severe emotional exhaustion for 62% of responses, 73% for depersonalization, and 37% for PA. All categories examined (emotional exhaustion, depersonalization, PA, and EI) saw improvement in scores across 3 administrations. CONCLUSIONS: Improvements in burnout and EI scores were seen across 3 administrations of surveys without any intervention. In the future, assessing PA may have the highest potential to evaluate burnout indirectly. Designing a curriculum for EI may assist with preventing burnout.

The Value Proposition for Complex Abdominal Wall Reconstruction: How to Make It Work.

BACKGROUND: The challenge for health care in the 21st century is to understand how to measure and improve value in the context of each patient care process for the entire cycle of care. For patients who undergo an abdominal wall reconstruction, there is a great opportunity to improve value because of the high cost and variability in outcomes for this complex operation. METHODS: For almost a decade, our hernia team has been applying the principles of systems and data science to actual patient care. Tools from systems and data science applied to patient care include clinical quality improvement and nonlinear analytical methods such as factor analysis. The most important outcome to measure and improve is the value of care provided for the entire cycle of care. RESULTS: Many measurement and improvement ideas have been applied to the abdominal wall reconstruction process in our hernia program, including the use of a less costly long-term resorbable mesh, multimodal pain management and enhanced recovery process improvement ideas, and surgical technique improvements that have led to decreased wound complications and the elimination of abdominal wall drains. More recently, the data analysis has shown an opportunity to improve outcomes through a robust prehabilitation program, including cognitive therapy to induce neural rewiring before surgery. CONCLUSIONS: Improving value for patients who undergo abdominal wall reconstruction and for all patients in our global health care system should be a unifying goal. Understanding and applying systems and data science tools appropriately are necessary to achieve this goal.

Laparoscopic approach for the treatment of chronic groin pain after inguinal hernia repair : Laparoscopic approach for inguinodynia.

BACKGROUND: Traditional methods of clinical research may not be adequate to improve the value of care for patients with complex medical problems such as chronic pain after inguinal hernia repair. This problem is very complex with many potential factors contributing to the development of this complication. METHODS: We have implemented a clinical quality improvement (CQI) effort in an attempt to better measure and improve outcomes for patients suffering with chronic groin pain (inguinodynia) after inguinal hernia repair. Between April 2011 and June 2016, there were 93 patients who underwent 94 operations in an attempt to relieve pain (1 patient had two separate unilateral procedures). Patients who had prior laparoscopic inguinal hernia repair (26) had their procedure completed laparoscopically. Patients who had open inguinal hernia repair (68) had a combination of a laparoscopic and open procedure in an attempt to relieve pain. Initiatives to attempt to improve measurement and outcomes during this period included the administration of pre-operative bilateral transversus abdominis plane and intra-operative inguinal nerve blocks using long-acting local anesthetic as a part of a multimodal regimen, the introduction of a low pressure pneumoperitoneum system, and the expansion of a pre-operative questionnaire to assess emotional health pre-operatively. RESULTS: The results included the assessment of how much improvement was achieved after recovery from the operation. Forty-five patients (48%) reported significant improvement, 39 patients (41%) reported moderate improvement, and 10 patients (11%) reported little or no improvement. There were 3 (3%) complications, 13 (11%) hernia recurrences, and 15 patients (13%) developed a new pain in the inguinal region after the initial pain had resolved. CONCLUSIONS: The principles of CQI can be applied to a group of patients suffering from chronic pain after inguinal hernia repair. Based on these results additional process improvement ideas will be implemented in an attempt to improve outcomes.

Real-World Clinical Quality Improvement for Complex Abdominal Wall Reconstruction.

INTRODUCTION: Traditional methods of clinical research may not be adequate to improve the value of care for patients undergoing abdominal wall reconstruction (AWR). These patients are prone to high complication rates and high costs. Here, we describe a clinical quality improvement (CQI) effort to enhance outcomes for patients undergoing AWR. MATERIALS AND METHODS: CQI was applied for the entire care cycle for consecutive patients who underwent AWR from August 2011-September 2015. Initiatives for improving value during this period included use of long-term resorbable synthetic mesh as well as administration of preoperative bilateral transversus abdominus plane (TAP), and intraoperative abdominal wall blocks using long-acting bupivacaine as a part of a multimodal regimen. Outcomes data that measure value in the context of AWR were collected to compare outcomes for the patients who received TAP blocks only, TAP and intraoperative blocks, and those who received no block. RESULTS: One hundred and two patients who had AWR for abdominal wall pathology were included. Outcomes including total opioid use, duration of stay and opioid use in the postanesthesia care unit (PACU), length of hospital stay (LOS), major wound complications, and costs, all improved over time. Specifically, PACU opioid use, total opioid use, and LOS were decreased in the two groups that received blocks versus a group that did not have any type of block. CONCLUSIONS: CQI program implementation in patients undergoing AWR resulted in measurable improvement of value-based outcomes over time. A CQI effort applied to the entire patient cycle of care should be routinely utilized.

A Clinical Quality Improvement (CQI) Project to Improve Pain After Laparoscopic Ventral Hernia Repair.

Patients who undergo laparoscopic ventral hernia repair can have significant post-operative pain and discomfort from both somatic pain due to mesh fixation and visceral pain due to CO2 insufflation pressure. In an attempt to improve outcomes, a Clinical Quality Improvement (CQI) project was implemented by a multi-disciplinary hernia team. CQI tools were applied for consecutive patients who underwent laparoscopic ventral hernia repair from June 2012 through September 2015 (39 months). Initiatives for improved patient outcomes during this period included the administration of a transversus abdominis plane (TAP) block and/or an intra-operative block with long-acting local anesthetic first, and then a low pressure pneumoperitoneum (LPP) system was implemented later in the project. One-hundred-twenty patients who underwent a laparoscopic ventral/incisional hernia repair were included in the analysis. Fifty-three patients had no block and had conventional insufflation at 15 mmHg (No Block-No LPP group). Outcomes for this group included a median time in the Post-Anesthesia Care Unit (PACU) of 126 minutes, a median length of stay of 4.0 days, a median use of opioid morphine equivalents (MEQ) in the PACU of 10.0, and a total use of opioid MEQ for the entire hospital stay of 100.0. Thirty-seven patients had blocks with a long-acting local anesthetic and conventional insufflation at 15 mmHg (Block only group). Outcomes for this group showed improvement for all outcomes, but none were statistically significant. Thirty patients had blocks with a long-acting local anesthetic and a low pressure pneumoperitoneum system with a standard pressure of 8 mmHg. Outcomes for this group included a median time in PACU of 83.6 minutes, a median length of stay of 1.5 days, a median amount of opioid use in the PACU of 5.0 MEQ, and a median use of opioid use for the entire hospital stay of 26.0 MEQ. All of these outcomes were statistically significant improvements compared with the No Block-No LPP and Block only groups. Implementation of a CQI program, including long-acting local anesthetic blocks and a low pressure pneumoperitoneum system as part of a multi-modal pain strategy for patients who underwent laparoscopic ventral hernia repair, was associated with decreased PACU time, decreased length of stay, and less opioid use in the PACU and for the entire hospital stay.
