Video Review Can Measure Surgical Robotic Skill Development in a Resident Robotic Hernia Curriculum: A Retrospective Cohort Study

Background: Hernia repairs are one of the most common general surgery procedures and an essential part of training for general surgery residents. The widespread incorporation of robotic hernia repairs warrants the development of a procedure-specific robotic curriculum to assist novice surgeons in improving technical skills. Objective: To evaluate a robotic hernia simulation-based curriculum for general surgery residents using video review. Methods: Retrospective cohort study of PGY-3 general surgery residents from the University of Chicago from 2019 to 2021. The residents completed inguinal hernia repair (IHR) and ventral hernia repair (VHR) drills as part of a robotic simulation curriculum. The drills were recorded and graded according to the modified objective structured assessment of technical skills (OSATS) and time to completion. The drills were completed by 3 attending surgeons to establish gold-standard benchmarks. Results: In total, 20 residents started the curriculum, 19 completed all IHR drills and 17 completed all VHR drills. Attending surgeon total OSATS scores and time to completion were significantly better than the trainees on the first attempt (P < 0.05). When comparing 1st to 4th attempt, resident OSATS scores improved significantly for IHR (15.5 vs 23.3; P < 0.001) and VHR (16.8 vs 23.3; P < 0.001). Time also improved over 4 attempts (IHR: 28.5 vs 20.5 minutes; P < 0.001 and VHR: 29.6 vs 21.2 minutes; P < 0.001). Residents achieved attending-level OSATS scores by their fourth attempt for VHR, but not for IHR. Residents did not achieve attending-level times for either hernia drills. Conclusions: The robotic hernia curriculum improved resident performance on hernia repair drills and was well-received by the residents.

Cross-cultural adaptation and validation of Carolinas Comfort Scale to Brazilian Portuguese for inguinal hernia.

Inguinal hernias are highly prevalent worldwide and its surgical repair is one of the most common procedures in general surgery. The broad use of mesh has decreased the recurrence rates of inguinal hernia to acceptable levels, thus centering the attention on Quality of Life as a pivotal postoperative outcome. Carolinas Comfort Scale is a well-studied questionnaire designed to identify Quality of Life changes following hernia repair with mesh techniques. The aim of this study is to validate the CCS in Brazilian Portuguese for inguinal hernias. The original CCS was translated into Brazilian Portuguese according to cross-cultural adaptation guidelines. We conducted a cross-sectional study in individuals aged 18 and above who had undergone inguinal laparo-endoscopic hernia repair for at least 6months prior, between January 2019 and August 2022, at a Brazilian tertiary hospital. Participants answered an online survey containing the Brazilian CCS and the generic Patient-Reported Outcome Measure (PROM) Short-Form Health 36 (SF-36). Participants answered the same questionnaires in the follow-up after at least three weeks, with an additional question about satisfaction with surgery results. The survey was completed by 115 patients, of whom 78 (67%) responded to the follow-up questionnaire after 3 to 10weeks. CCS showed excellent internal consistency, with Cronbach's α of 0.94. Intraclass correlation coefficient ranged from 0.60 to 0.82 in the test-retest analysis. Compared to SF-36, a strong correlation was observed in the physical functioning dimension, and a moderate correlation was found in role-physical and bodily pain (Pearson's Coefficient Correlation = 0.502, 0.338 and 0.332 respectively), for construct analysis. The mean CCS score was significantly lower (p < 0.001) among satisfied patients compared to the unsatisfied ones. The Brazilian version of CCS is a valid and reliable method to assess long-term quality of life after inguinal laparo-endoscopic hernia repair.

Do We Need Preoperative Antibiotics in Common General Pediatric Surgery Procedures?

Background There are limited studies on the necessity of preoperative antibiotics in surgeries for undescended testis (UDT), inguinal hernia (IH), and umbilical hernia (UH) in children. Here, we investigated the relationship between preoperative antibiotic use and surgical site infection (SSI) incidence in surgeries for UDT, IH, and UH in children. Methods Patients who underwent surgery for IH were subdivided based on the surgical form into those who underwent (i) open IH (OIH) repair and (ii) laparoscopic percutaneous extraperitoneal closure (LPEC). Medical records of patients who underwent surgeries for UDT and IH or UH were retrospectively examined. The SSI incidence was compared between patients receiving and not receiving preoperative antibiotics. In patients who underwent surgery for UH or LPEC, the relative risk of SSI postoperatively in the inguinal region (including surgery for UDT and OIH repair) was examined. Results In total, 926 patients with 1389 wounds were included in this study. SSI rates in patients who underwent surgeries for UDT and UH, OIH repair, and LPEC were 0.2% and 2.7%, 0.3%, and 0.4%, respectively. These rates were not significantly different between patients receiving and not receiving preoperative antibiotics. In patients who underwent surgery for UH, the relative risk of SSI was statistically significant at 9.8 compared with that in patients who underwent surgeries in the inguinal region (95% CI = 1.3-74; p = 0.013). Conclusions Preoperative antibiotics are unnecessary in surgeries for UDT and OIH repair. Patients undergoing surgery for UH should be given extensive care as they are at a high risk of SSI.

Toward Environmentally sustainable surgery: Waste recycling in general surgery operating room. Preliminary cognitive audit.

It is common practice to classify waste from the operating theater as "clinical". The development of sustainable policies could have a significant impact. In the first phase, our study aims to measure general surgery waste and to assess the potential financial and carbon savings of appropriate recycling. Based on this information, we will plan for a second phase in which educational interventions will be put in place to promote waste segregation in surgical environments. We conducted a preliminary cognitive audit of the most common general surgery procedures to examine the types and quantity of waste produced. We calculated the economic and environmental impacts of disposing of waste treated as clinical or general, and we measured how much of it could actually be recycled. Then, we attempted a projection of the savings we could expect if recycling policies were implemented. We found that more than 30% of total waste was actually recyclable. Considering a projection based on annual procedures performed in our hospital, we estimated that for each kind of surgical procedure, we could expect a reduction of the carbon footprint by approximately 6%, and an average 3% reduction in costs every year, only by improving waste segregation in the general surgery operating rooms. There could be a great potential for reducing environmental and economic footprint of the operating rooms by promoting waste recycling protocols. Surgeons are in a unique position to implement for these protocols. Interventions should be codesigned with theater staff to create a "green culture".

Quality of life among older patients after elective ventral hernia repair: A retrospective review

BackgroundVentral hernia repair is a common elective general surgery procedure among older patients, a population at greater risk of complications. Prior research has demonstrated improved quality of life in this population despite increased risk of complications. This study sought to assess the relationship between post–ventral hernia repair quality of life and patient frailty. We hypothesized that frail patients would report smaller gains in quality of life compared to the non-frail group. MethodsThe Abdominal Core Health Quality Collaborative was used to identify a cohort of patients 65 years of age or older undergoing elective ventral hernia repair from 2018 to 2022. Patients were categorized based on their modified frailty index scores as not frail/prefrail, frail, and severely frail. Quality of life was assessed using a patient-reported 12-item scale preoperatively, 30 days, 6 months, and 1 year postoperatively. ResultsA total of 3,479 patients were included: 30.93% non-frail, 47.17% frail, and 21.90% severely frail. Severely frail patients had lower quality of life scores at baseline (P = .001) but reported higher quality of life at both 30 days (1.24 points higher, 95% confidence interval (–1.51, 2.52), P = .010) and 6 months (0.92 points higher, 95% confidence interval (–2.29, 4.13), P = .005). Severely frail patients had higher rates of surgical site complications (P < .001) but no difference in 30-day readmissions. ConclusionOur results found that frail patients reported the greatest increase in quality of life 1 year from baseline, showing that they, when selected appropriately, can gain equal benefits and have similar surgical outcomes as their non-frail counterparts.

Outcomes and quality of life of frail patients following elective ventral hernia repair: Retrospective review of a national hernia collaborative

BackgroundVentral hernia repair (VHR) is one of the most common general surgery procedures among older adults but is often deferred due to a higher risk of complications. This study compares postoperative quality of life (QOL) and complications between frail and non-frail patients undergoing elective VHR. We hypothesized that frail patients would have higher complication rates and smaller gains in quality of life compared to non-frail patients. Study designPatients 65 years of age and older, undergoing elective VHR between 2018 and 2022 were selected from the ACHQC (Abdominal Core Health Quality Collaborative) and grouped based on frailty scores obtained using the Modified Frailty Index (mFI-5). Logistic regression adjusting for hernia characteristics (size, recurrent, parastomal, incisional) were performed for 30-day outcomes including surgical site infections (SSI), surgical site occurrences (SSO), surgical site infections/occurrences requiring procedural intervention (SSOPI), and readmission. Multivariable analyses controlling for patient and procedure characteristics were performed comparing QOL scores (HerQLes scale, 0–100) at baseline, 30 days, 6 months and 1 year postoperatively. ResultsA total of 4888 patients were included, 29.17% non-frail, 47.87% frail, and 22.95% severely frail. On adjusted analysis, severely frail patients had higher odds of SSO (most commonly seroma formation) but no evidence of a difference in SSI, SSOPI, readmission or mortality. Severely frail patients had lower median QOL scores at baseline (48.3/100, IQR 26.1–71.7, p ​= ​0.001) but reported higher QOL scores at both 30-days (68.3/100, IQR 41.7–88.3, p ​= ​0.01) and 6-months (86.7/100, IQR 65.0–93.3, p ​= ​0.005). ConclusionSeverely frail patients reported similar increases in QOL and similar complications to their not frail counterparts. Our results demonstrate that appropriately selected older patients, even those who are severely frail, may benefit from elective VHR in the appropriate clinical circumstance.

Implementation of Guidelines Limiting Postoperative Opioid Prescribing at a Children's Hospital.

Variability in opioid-prescribing practices after common pediatric surgical procedures at our institution prompted the development of opioid-prescribing guidelines that provided suggested dose limitations for narcotics. The aims of this study were to improve opioid prescription practices through implementation of the developed guidelines and to assess compliance and identify barriers preventing guideline utilization. We conducted a single-center cohort study of all children who underwent the most common outpatient general surgery procedures at our institution from August 1, 2018, to February 1, 2020. We created guidelines designed to limit opioid prescription doses based on data obtained from standardized postoperative telephone interviews. Three 6-month periods were evaluated: before guideline implementation, after guideline initiation, and after addressing barriers to guideline compliance. Targeted interventions to increase compliance included modification of electronic medical record defaults and provider educations. Differences in opioid weight-based doses prescribed, filled, and taken, as well as protocol adherence between the 3 timeframes were evaluated. A total of 1033 children underwent an outpatient procedure during the 1.5-year time frame. Phone call response rate was 72.22%. There was a significant sustained decrease in opioid doses prescribed ( P < 0.0001), prescriptions filled ( P = 0.009), and opioid doses taken ( P = 0.001) after implementation, without subsequent increase in reported pain on postoperative phone call ( P = 0.96). Protocol compliance significantly improved (62.39% versus 83.98%, P < 0.0001) after obstacles were addressed. Implementation of a protocol limiting opioid prescribing after frequently performed pediatric general surgery procedures reduced opioids prescribed and taken postoperatively. Interventions that addressed barriers to application led to increased protocol compliance and sustained decreases in opioids prescribed and taken without a deleterious effect on pain control.

Variation in Competence of Graduating General Surgery Trainees

To examine the readiness of general surgery residents in their final year of training to perform 5 common surgical procedures based on their documented performance during training. Intraoperative performance ratings were analyzed using a Bayesian mixed effects approach, adjusting for rater, trainee, procedure, case complexity, and postgraduate year (PGY) as random effects as well as month in academic year and cumulative, procedure-specific performance per trainee as fixed effects. This model was then used to estimate each PGY 5 trainee's final probability of being able to independently perform each procedure. The actual, documented competency rates for individual trainees were then identified across each of the 5 most common general surgery procedures: appendectomy, cholecystectomy, ventral hernia repair, groin hernia repair, and partial colectomy. This study was conducted using data from members of the SIMPL collaborative. A total of 17,248 evaluations of 927 PGY5 general surgery residents were analyzed from 2015 to 2021. The percentage of residents who requested a SIMPL rating during their PGY5 year and achieved a ≥90% probability of being rated as independent, or "Practice-Ready," was 97.4% for appendectomy, 82.4% for cholecystectomy, 43.5% for ventral hernia repair, 24% for groin hernia repair, and 5.3% for partial colectomy. There is substantial variation in the demonstrated competency of general surgery residents to perform several common surgical procedures at the end of their training. This variation in readiness calls for careful study of how surgical residents can become more adequately prepared to enter independent practice.

MORPHOLOGICAL FEATURES OF THE REPARATIVE PROCESS IN THE PLASTIC SECTION OF THE MUSCLE-APONEUROTIC DEFECT IN THE EXPERIMENT USING STEM CELLS

Abstract. Anterior abdominal wall hernia repair is one of the most common procedures in general surgery. Very often, the parameters of the quality of life of operated patients with ventral hernias of the anterior abdominal wall during the fi rst year after the operation, according to a number of criteria, are signifi cantly better with alloplastic with polypropylene mesh, in contrast to the use of hernioplasty with the use of inert suture material. Hernias of the anterior abdominal wall (ventral hernias) most often occur after surgical intervention on the organs of the abdominal cavity and are considered postoperative complications arising in anatomically weak areas and under the infl uence of mechanical factors. The goal of the work. To experimentally investigate the eff ect of mesenchymal stem cells on the regeneration of muscle fi bers and their reparative properties in the area of postoperative wounds. When modeling a muscle- aponeurotic defect of the anterior abdominal wall with plasticity with own tissues and plasticity with an allograft in combination with injections of mesenchymal stem cells. The study was conducted on 38 white rats of both sexes, the initial weight of each animal was 215±12 g, the experimental animals were kept in the same conditions with full compliance with bioethical norms. All animals of groups 1 and 2 were experimentally modeled a muscle- aponeurotic defect of the anterior abdominal wall by an acute method up to 2.5 cm in diameter, followed by layer-by-layer suturing of this defect with a continuous wraparound single-row suture, «Vicryl» 3/0 with a barb was used as suture material with a needle In the 2nd group, plastic surgery was performed using the «on lay» technique with polypropylene mesh and suture material «Vicryl» 3/0 with a barbed needle, and mesenchymal stem cell injections were additionally performed. At the plastic site of the muscle- aponeurotic defect, the tissue of the anterior abdominal wall was taken in full layers for further histological examination. Histological examination of the wound tissues of animals of the control group 10 days after surgery showed that the wound defect was fi lled with granulation tissue at an early stage of maturation. After 30 days, the wound defect was fi lled with young loose connective tissue, in which there were sporadic islands of granulation tissue. In the area of the wound defect of 2 groups of experimental animals, after 10 days we detected maturing granulation tissue. Visually, the area of the lesion itself decreased. On the 30th day of the study, there was no granulation tissue, the wound defect was fi lled with fully matured newly formed and vascularized connective tissue. During the histological examination, it was found that as a result of the combined use of polypropylene mesh and stem cells, the regeneration of the wound defect is intensifi ed and its healing is accelerated.

Missing Narrative: Examining the Impact of Disability on Post-Operative Infectious Complications.

Background: More than 20% of the population in the United States suffers from a disability, yet the impact of disability on post-operative outcomes remains understudied. This analysis aims to characterize post-operative infectious complications in patients with disability. Patients and Methods: This was a retrospective review of the National Readmission Database (2019) among patients undergoing common general surgery procedures. As per the U.S. Centers for Disease Control and Prevention (CDC), disability was defined as severe hearing, visual, intellectual, or motor impairment/caregiver dependency. A propensity-matched analysis comparing patients with and without a disability was performed to compare outcomes, including post-operative septic shock, sepsis, bacteremia, pneumonia, catheter-associated urinary tract infection (CAUTI), urinary tract infection (UTI), catheter-associated blood stream infection, Clostridioides Difficile infection, and superficial, deep, and organ/space surgical site infections during index hospitalization. Patients were matched using age, gender, comorbidities, illness severity, income, neighborhood, insurance, elective procedure, and the hospital's bed size and type. Results: A total of 710,548 patients were analysed, of whom 9,451(1.3%) had at least one disability. Motor disability was the most common (3,762; 40.5%), followed by visual, intellectual, and hearing impairment. Patients with disability were older (64 vs. 57 years; p < 0.001), more often insured under Medicare (65.2% vs. 37.3% p < 0.001) and had more medical comorbidities (Elixhauser comorbidity score ≥3; 69.2% vs. 41.9%; p < 0.001). After matching, 9,292 pairs were formed. Patients with a disability had a higher incidence of pneumonia (10.1% vs. 6.5%; p < 0.001), aspiration pneumonia (5.2% vs. 1.4%; p < 0.001), CAUTI (1.0% vs. 0.4%; p < 0.001), UTI (10.4% vs. 6.2%; p < 0.001), and overall infectious complications (21.8% vs. 14.5%; p < 0.001). Conclusions: Severe intellectual, hearing, visual, or motor impairments were associated with a higher incidence of infectious complications. Further investigation is needed to develop interventions to reduce disparities among this high-risk population.

The Effect of Mesh Fixation Methods on Pain Sensation After Laparoscopic Inguinal Hernia Repair

Aim: Groin hernia repair is one of the most common surgical procedure in general surgery. The use of prosthetic meshs has reduced the recurrence rate after inguinal hernia repair to less than 5%. Chronic pain is thought to be multi-factorial. Among these, surgical-related factors are the types of mesh used and fixation methods. It was aimed to evaluate the effect of the use of absorbable and non-absorbable screws for mesh fixation on post-operative pain during TEP repair.&#x0D; Material and Methods: The data of patients who were operated on by a single surgeon and who underwent TEP repair for unilateral or bilateral inguinal hernia were reviewed retrospectively. Post-operative first-week pain sensations were compared between patient groups in which absorbable and non-absorbable screws were used for patch fixation.&#x0D; Results: A total of 35 patients who were operated by a single surgeon and who underwent laparoscopic total extraperitoneal (TEP) repair for unilateral or bilateral inguinal hernia were included in the study. It was found that patients in the absorbable screw group felt statistically significantly less pain [VAS: 3 (2-7) vs. 4 (2-8); p=0.03].&#x0D; Conclusion: Chronic pain after patchy hernia repair is also seen as a late complication that can last up to 6 months. This study, which proves that the use of absorbable stabilizers leads to less pain in the early period, reveals that this method may also be a suitable method for preventing the development of possible chronic pain.

1129 LaCON: A Quality Improvement Project on Laparoscopic Cholecystectomy Operation Notes

Abstract Aim Accurate and comprehensive operation notes are crucial for patient care, quality assurance and medico-legal purposes. Laparoscopic cholecystectomy (LC) is one of the most common procedures in General Surgery, either in an Elective or Emergency setting. Therefore, there is a need for an accurate and standard way to document the operation notes for a safe immediate and late post-operative care, including follow-up. The LaCON project aims to evaluate and improve the quality of the operation notes. Method A retrospective review of operation notes of LCs performed at our institution between August-November 2022. Electronic notes were assessed against the Royal College of Surgeons’ Good Surgical Practice standard, consisting of 18 items. Results A total of 80 operation notes were reviewed. There was 100% compliance in surgeon’s name, operation procedure, incision, port sites, and closure technique. Other high-scoring items were indication (98%), operative findings (98%), operation date (91%) and assistant’s name (90%). Among the lowest-scoring items were detailed postoperative instructions (46%), designation as elective or emergency (38%), operative diagnosis (16%) and estimated blood loss (EBL) (8%). Conclusions We identified several areas for improvement in LC operation notes, such as a detailed and robust post-operative plan, a precise intraoperative diagnosis and information about EBL. The LaCON project highlighted the need to implement an electronic evidence-based proforma to standardise notes. This proforma will be accessible through a secure online app, in line with the local Hospital policies, and will allow accurate and contemporaneous record keeping and efficient extraction of operative data for analysis.

Transabdominal Preperitoneal Versus Lichtenstein Procedure for Inguinal Hernia Repair in Adults: A Comparative Evaluation of the Early Postoperative Pain and Outcomes.

Inguinal hernia repairs are one of the most common procedures in general surgery. In addition to classical open surgery, laparoscopic techniques, such as transabdominal preperitoneal (TAPP) and total extraperitoneal (TEP) hernia repair, have gained acceptance and are increasingly used for inguinal hernia repairs, and these three techniques arethe only standards for inguinal hernia repairs. This study aimed to compare the results of inguinal hernia repairs in adult patients using the TAPP patch technique and Lichtenstein techniques regarding the level of pain perceived one day after surgery and the number of days of hospitalization. A two-year study was performed on 129 patients who underwent TAPP vs. 109 patients who underwent Liechtenstein hernia repair. Our results revealed statistical significance for both variables (Tpain(233) = -7.12, p<0.001, d=2.92; Tdays of hospitalization(233) = -31.34, p<0.001, d=4.01). TAPP is a safe method for inguinal hernia repairs, allowing quick recovery and less postoperative pain than the classical Liechtenstein technique.

Surgical confidence when operating among residents in surgery – a cross-sectional study (SCAR study)

BackgroundSelf-confidence, is one of the critical variables influencing surgical resident’s abilities, and lack of confidence maybe a reason for not entering medical practice immediately. Measuring the level of confidence of senior surgical residents (SSRs) is a crucial step in assessing preparedness to practice. In this study, we aim to measure their confidence level and the factors that might contribute to it.MethodsCross-sectional survey conducted at King Abdulaziz University Hospital on SSRs in Saudi Arabia (SA). We approached 142 SSRs, 127 responded. Statistical analysis was performed using RStudio v 3.6.2. Descriptive statistics were performed using counts and percentages for categorical variables and using mean ± standard deviation for continuous variables. Multivariate linear regression (t-statistics) was used to assess the factors associated with confidence in performing essential procedures, while the association between demographics and residency-related factor with the number of completed cases was tested using Chi-square. The level of significance was determined as 0.05.ResultsResponse rate was 89.4%. Among surveyed residents, 66% had completed < 750 cases as a primary surgeon. More than 90% of SSRs were confident in performing appendectomy, open inguinal hernia repair, laparoscopic cholecystectomy, and trauma laparotomy, while 88% were confident in being on-call in level-I trauma center. No difference was noted in confidence level in relation to the number of performed cases. Residents from the Ministry of Health accounted for 56.3% of the study population and showed a higher confidence level compared to others. 94% of SSRs plan to pursue fellowship training program.ConclusionThe study showed that the confidence of SSRs in performing common general surgery procedures was as expected. However, it’s important to recognize that confidence doesn’t necessarily reflect competence. Considering the majority of SSRs planned to pursue fellowship training programs, it may be time to consider changing the structure of surgical training in SA to a modular format to allow earlier and more intensive exposure.

What factors impact surgical operative time when teaching a resident in the operating room

PurposeResident involvement would likely lead to prolonged operative time of a surgical case performed at academic medical centers. However, little is known about factors beneath this phenomenon. The purpose of this study was to investigate whether factors from case (procedure type, surgical case complexity, and surgical approach), teacher (attending surgeon experience and gender), and learner (resident postgraduate training year and gender) would influence operative time of surgical cases involved teaching a resident (SCT). MethodsA single-institution retrospective analysis of 3 common general surgery procedures, including cholecystectomies, colectomies, and inguinal hernia, with involvement of general surgery residents between 2016 and 2020 was conducted. Surgical operative time was defined as the "cut-to-close” time from incision to completion of wound closure. Analysis of variance for continuous variables and multivariable linear regression were applied. ResultsA total of 4,417 eligible SCT were included. The average operative time was 114.8 ± 78.7 min. SCT with male resident involvement showed a significantly longer operative time than those with female residents (117 vs. 112, p = 0.01). Comparable operative time was observed between male and female attending surgeon cases (115.5 vs. 110.8, p = 0.15). SCT operating time decreased with increased resident training level, except for SCT with involvement of Year2 residents. SCT with Year5 residents demonstrated the lowest time to case completion (110.5 min); SCT with major complications took least time to complete (105.7 min). Univariate and multivariate analysis revealed resident training year level, resident gender, and case complexity as factors associated with significant differences in operative time. Attending surgeon experience, surgeon gender, surgical approach, and procedure type did not impact SCT operative time. ConclusionOur study findings suggest resident training level, resident gender, and case complexity are factors significantly associated with SCT operative time of cholecystectomies, colectomies, and inguinal hernia. Attending surgeons are recommended to factor them into pre-operative planning.

An Outcomes-Focused Analysis of Laparoscopic and Open Surgery in a Nigerian Hospital.

The benefits of laparoscopic surgery such as swifter recovery and fewer wound complications, elude much of the developing world. Nigeria, a lower middle-income country, is the most populous sub-Saharan nation; an excellent model for studying the impact of laparoscopy in resource-constrained environments. The Department of Surgery at the Obafemi Awolowo University Teaching Hospital and the University of Utah's Center for Global Surgery present a study of laparoscopic surgery cases in sub-Saharan Africa. A retrospective chart review of 261 patients compared open and laparoscopic surgical outcomes for three common general surgery procedures: open versus laparoscopic cholecystectomy and appendectomy, and open laparotomy versus diagnostic laparoscopy for biopsy of intra-abdominal mass. The primary outcome was total length of stay (LOS); secondary outcomes included wound complications, analgesia and antibiotic use, time to oral intake, and patient charges. Total LOS for laparoscopic surgery was significantly shorter compared to analogous open procedures (4.7 vs 11.5 days). Postoperative LOS was also shorter (2.6 vs 8.2 days). There were no differences in wound complications. Median charges to patients were lower for laparoscopic versus open procedures ($184 vs $217 USD). The introduction of laparoscopy allows for significantly shorter LOS and equivalent wound complications in the context of a sub-Saharan teaching hospital. Concerns regarding higher costs of care for patients do not appear to be a significant issue. Further work is needed to evaluate costs to the hospital system as a whole, including procurement and maintenance of laparoscopic equipment.

Social Vulnerability and Emergency General Surgery among Medicare Beneficiaries.

Although the Social Vulnerability Index (SVI) was created to identify vulnerable populations after unexpected natural disasters, its ability to identify similar groups of patients undergoing unexpected emergency surgical procedures is unknown. We sought to examine the association between SVI and outcomes after emergency general surgery. This study is a cross-sectional review of 887,193 Medicare beneficiaries who underwent 1 of 4 common emergency general surgery procedures (appendectomy, cholecystectomy, colectomy, and ventral hernia repair) performed in the urgent or emergent setting between 2014 and 2018. These data were merged with the SVI at the census-track level of residence. Risk-adjusted outcomes (30-day mortality, serious complications, readmission) were evaluated using a logistic regression model accounting for age, sex, comorbidity, year, procedure type, and hospital characteristics between high and low social vulnerability quintiles and within the 4 SVI subthemes (socioeconomic status; household composition and disability; minority status and language; and housing type and transportation). Compared with beneficiaries with low social vulnerability, Medicare beneficiaries living in areas of high social vulnerability experienced higher rates of 30-day mortality (8.56% vs 8.08%; adjusted odds ratio 1.07; p < 0.001), serious complications (20.71% vs 18.40%; adjusted odds ratio 1.17; p < 0.001), and readmissions (16.09% vs 15.03%; adjusted odds ratio 1.08; p < 0.001). This pattern of differential outcomes was present in subgroup analysis of all 4 SVI subthemes but was greatest in the socioeconomic status and household composition and disability subthemes. National efforts to support patients with high social vulnerability from natural disasters may be well aligned with efforts to identify communities that are particularly vulnerable to worse postoperative outcomes after emergency general surgery. Policies targeting structural barriers related to household composition and socioeconomic status may help alleviate these disparities.

EGS P15 Role of electronic consent in emergency surgery – A QIP in a high volume surgical emergency unit at a tertiary hospital

Abstract Background The Royal College of Surgeons of England discusses the significance of maintaining a written record of consent in addition to completing the consent form under section 4.10 of the supported decision-making guide to good practice - “any written information given to the patient should also be recorded and copies should be included in the patient's notes”. Studies show high error rates (27–50%) with handwritten consent forms due to poor legibility, incomplete/ inaccurate information, increased variability, and risk of misplacement. The consequences of these errors can lead to poor patient experience as well as unfavourable outcomes at the operational and institutional levels. Missing or incomplete consent is also the most common reason for first case delay (average 1–75mins). This prompted the QIP and generation of a standard template for the common emergency general surgery procedures in a high-volume Surgical Emergency Unit (SEU) at the John Radcliffe Hospital. Methods Procedure-specific Electronic Surgical Consent (eSConsent) template for common emergency general surgery operations was added to the online database to easily be added to the electronic patient record. The format, as outlined below, was designed to allow even junior surgical trainees to adapt and perform the consent process early on in their placement- Results The consent for all the emergency general surgery cases in a given week was reviewed and the compliance to maintaining eSConsent was audited. The first cycle between 20th-26th September 2021 showed compliance of only 18% (9 out of 49 operations). After discussing the audit findings with the members of the surgical team involved in the consenting process in the local meeting and implementing eSConsent, the compliance increased to 83.7% (36 of 43 cases) in the following week, 78% (33 of 43 cases) between 12th-18th November 2021 and 73% (28/38 operations) in the beginning of March 2022. Conclusions A consent form is a medicolegal document. Health care systems have taken advantage of technology to facilitate accuracy and robust monitoring. The emergency surgical consent process can benefit from this to avoid delays, errors and litigation. This transition is justifiable from our results and easily translated to practice particularly by using simple technology demonstrated in our QIP. Challenges including trainee changeover and new recruitments will expectedly affect the compliance of eSConsent but a proper induction to ensure adequate staff education will help overcome this.

Social Vulnerability and Emergency General Surgery among Medicare Beneficiaries

INTRODUCTION: Although the Social Vulnerability Index (SVI) was created to identify vulnerable populations after natural disasters, its ability to identify similar groups of patients after emergency general surgery is unknown. We aimed to examine the association between SVI and outcomes after emergency general surgery. METHODS: Cross-sectional review of 887,193 Medicare beneficiaries who underwent 1 of 4 common emergency general surgery procedures (appendectomy, cholecystectomy, colectomy, and ventral hernia repair) performed in the urgent or emergent setting between 2014 and 2018. These data were merged with the SVI at the census track level of residence. Risk-adjusted outcomes (30-day mortality, serious complication, readmission) were evaluated using a logistic regression model accounting for age, sex, comorbidity, year, procedure type, and hospital characteristics between high and low social vulnerability quintiles and within the 4 SVI subthemes (socioeconomic status, household composition/disability, minority status/language, and housing type/transportation). RESULTS: Compared with beneficiaries with low social vulnerability, Medicare beneficiaries living in areas of high social vulnerability experienced higher rate of 30-day mortality (8.6% vs 8.1%; adjusted odds ratio [OR] 1.07; p < 0.001), serious complication (20.7% vs 18.4%; OR 1.17; p < 0.001), and readmission (16.1% vs 15.0%; OR 1.08; p < 0.001). This pattern of differential outcomes was present in subgroup analysis of all 4 SVI subthemes but was greatest in the housing/transportation subtheme. CONCLUSION: National efforts to support patients with high social vulnerability from natural disasters may be well aligned with efforts to identify communities that are particularly vulnerable to worse postoperative outcomes after emergency general surgery. Policies targeting housing/transportation may help alleviate these disparities.
