Morbidity and mortality conferences in general surgery: a narrative systematic review.

Background: In medical and surgical departments around the world, morbidity and mortality conferences (MMC) serve dual roles: they are cornerstones of quality-improvement programs and provide timely opportunities for education within the urgent context of clinical care. Despite the widespread adoption of MMCs, adverse events and preventable errors remain high or incompletely characterized, and opportunities to learn from and adjust to these events are frequently lost. This review examines the published literature on strategies to improve surgical MMCs. Methods: We searched OVID Medline, PubMed, Embase and CENTRAL. We defined our combination of search terms using a PICO (population, intervention, comparison, outcome) model, focusing on the use of MMCs in general surgery. Results: The MMC literature focused on 5 themes: educational value, error analysis, case selection and representation, attendance and dissemination. Strategies used to increase educational value included limiting case presentation time to 15-20 minutes, mandatory brief literature reviews, increasing audience interaction, and standardizing presentations using a PowerPoint template or SBAR (situation, background, assessment, recommendation) format. Interventions to improve error analysis included focused discussion on causative factors and taxonomic error analysis. Case selection was improved by using an electronic clinical registry, such as the National Surgery Quality Improvement Program, to better capture incidence of morbidity and mortality. Attendance was improved with teleconferencing. Dissemination strategies included MMC newsletters, incorporating MMCs into plan-do-check-act cycles, and surgeon report cards. Conclusion: Greater standardization of best practices may increase the quality improvement and educational impact of MMCs and provide a baseline to measure the effect of new MMC format innovations on the clinical and educational performance of surgical systems.

Contexte: Dans les services de médecine et de chirurgie du monde entier, les conférences sur la morbidité et la mortalité (CMM) jouent 2 rôles : elles forment la pierre angulaire des programmes d'amélioration de la qualité de soins et fournissent l'occasion de faire de l'enseignement dans le contexte même des soins cliniques immédiats. Malgré la popularité grandissante des CMM, le nombre d'événements indésirables et d'erreurs évitables demeure élevé ou mal caractérisé et on perd beaucoup d'occasions d'apprendre de ces événements et d'apporter les changements qui s'imposent. La présente revue analyse la littérature publiée sur les stratégies d'amélioration des CMM en chirurgie. Méthodes: Nous avons interrogé OVID Medline, PubMed, Embase et CENTRAL. Nous avons défini nos combinaisons de mots clés à l'aide du modèle PICO (population, intervention, comparaison et résultat [outcome]), en mettant l'accent sur l'utilisation des CMM en chirurgie générale. Résultats: La littérature sur les CMM se concentrait sur 5 thèmes : valeur didactique, analyse des erreurs, sélection et représentation des cas, participation et dissémination. Les stratégies utilisées pour accroître la valeur didactique incluaient limiter la durée des présentations de cas à 15­20 minutes, présenter de brèves revues de la littérature, favoriser les interactions avec l'auditoire et standardiser les présentations au moyen de modèles PowerPoint ou SBAR (situation, background, assessment, recommendation). Les interventions visant à améliorer l'analyse des erreurs incluaient une discussion sur les facteurs causaux et l'analyse des erreurs taxonomiques. La sélection des cas a été améliorée au moyen d'un registre clinique électronique comme le National Surgery Quality Improvement Program, pour mieux suivre l'incidence de la morbidité et de la mortalité. Les systèmes de téléconférences ont amélioré la participation. Parmi les stratégies de dissémination, mentionnons les bulletins sur les CMM, leur intégration aux cycles planifier/faire/vérifier/agir et les relevés de notes des chirurgiens. Conclusion: Une meilleure standardisation des pratiques optimales pourrait améliorer davantage la qualité des soins et augmenter l'impact didactique des CMM en plus d'offrir une base de référence pour mesurer l'effet des nouvelles mesures appliquées aux CMM sur le rendement clinique et didactique des systèmes chirurgicaux.

Integrating intraoperative physiology data into outcome analysis for the ACS Pediatric National Surgical Quality Improvement Program.

BACKGROUND: The Pediatric National Surgical Quality Improvement Program (P-NSQIP) samples surgical procedures for benchmarking and quality improvement. While generally comprehensive, P-NSQIP does not collect intraoperative physiologic data, despite potential impact on outcomes. AIMS: The aims of this study were (a) to describe a methodology to augment P-NSQIP with vital signs data and (b) demonstrate its utility by exploring relationships that intraoperative hypothermia and hypotension have with P-NSQIP outcomes. METHODS: Vital signs from 2012 to 2016 were available in a research databank. Episodes of hypotension and hypothermia were extracted and recorded alongside local P-NSQIP data. Multivariable regression analyses were performed to explore associations with undesired outcomes, including: surgical site infection, wound disruption, unplanned return to the operating room, and blood transfusion. Model variables were selected with the Akaike information criterion using 2012-2014 as the training set and validated with receiver operating characteristics analysis using 2015-2016 as the testing set. RESULTS: Data from 6737 patients were analyzed, with 43.9% female, median [interquartile range] age 5.8 [1.3-12.4] years, undergoing procedures lasting 118 [75-193] minutes. Hypothermia, observed in 45% of cases, was associated with wound disruption (odds ratio 1.75, 95% CI 1.1-2.83). Hypotension, observed in 60% of cases, was associated with unplanned returns (odds ratio 1.58, 95% CI 1.02-2.51), and transfusions (odds ratio 1.95, 95% CI 1.14-3.52). Surgical site infection, wound disruption, unplanned return, and transfusion models had areas under the receiver operating characteristic curve of 0.69/0.67, 0.59/0.63, 0.78/0.79, and 0.92/0.93 for validation models including hypothermia/hypotension respectively. CONCLUSION: Adding intraoperative vital signs to P-NSQIP data allowed identification of two modifiable risk factors: hypothermia was associated with increased wound disruption, and hypotension with increased blood transfusions and unplanned returns to the operating room. These findings may motivate prospective studies and prompt other centers and P-NSQIP to augment outcome data with intraoperative physiological data.

Do Microsurgical Outcomes Differ Based on Which Specialty Does the Operation? A NSQIP Analysis.

BACKGROUND: Because plastic surgeons do not "own" a specific anatomic region, other surgical specialties have increasingly assumed procedures historically performed by plastic surgery. Decreased case volume is postulated to be associated with higher complication rates. Herein, we investigate whether volume and surgical specialty have an impact on microsurgical complications, specifically surgical site infection (SSI) and reoperation rates. METHODS: The 2005-2015 National Surgical Quality Improvement Program participant use file was queried by Current Procedural Terminology code for breast and head/neck microsurgeries. Multivariate logistic regression was performed to compare the outcomes between surgical specialties. A cumulative frequency variable was introduced to investigate the effect of case volume on complication rates. RESULTS: We captured 6,617 microsurgical cases. Multivariate logistic regression revealed that although the rate of SSI was lower in plastic surgery compared with otolaryngology for head and neck reconstructions (13.3% versus 10.5%) and compared with general surgery for breast reconstructions (5.4% versus 4.7%), there was no significant difference between specialties (P = 0.13; P = 0.96). Increased case volume is negatively correlated with complications. CONCLUSIONS: Plastic surgery is at risk given case cannibalization by other specialties. We conclude that surgical specialty does not affect the rates of SSI and reoperation. We demonstrate a correlation between lower volumes and increased complications, implying that, once a specialty has amassed critical case experience, complication rates may decrease, and outcomes can be equivalent or superior. Case breadth and volumes should be maintained to preserve skills, optimize outcomes, and maintain the specialty as it currently exists.

High-Risk Plastic Surgery: An Analysis of 108,303 Cases From the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP).

BACKGROUND: There is a lack of large-scale data that examine complications in plastic surgery. A description of baseline rates and patient outcomes allows better understanding of ways to improve patient care and cost-savings for health systems. Herein, we determine the most frequent complications in plastic surgery, identify procedures with high complication rates, and examine predictive risk factors. METHODS: A retrospective analysis of the 2012 to 2016 American College of Surgeons National Surgical Quality Improvement Program plastic surgery data set was conducted. Complication rates were calculated for the entire cohort and each procedure therein. Microsurgical procedures were analyzed as a subgroup, where multivariate logistic regression models determined the risk factors for surgical site infection (SSI) and related reoperation. RESULTS: We identified 108 303 patients undergoing a plastic surgery procedure of which 6 264 (5.78%) experienced ≥1 complication. The outcome with the highest incidence was related reoperation (3.31%), followed by SSI (3.11%). Microsurgical cases comprised 6 148 (5.68%) of all cases, and 1211 (19.33%) experienced ≥1 complication. Similar to the entire cohort, the related reoperation (12.83%) and SSI (5.66%) were common complications. Increased operative time was a common independent risk factor predictive of a related reoperation or development of an SSI (P < 001). Of all microsurgeries, 23.3% had an operative time larger than 10 hours which lead to faster increase in reoperation likelihood. CONCLUSIONS: The complication rate in plastic surgery remains relatively low but is significantly increased for microsurgery. Increased operative time is a common risk factor. Two-team approaches and staged operations could be explored, as a large portion of microsurgeries are vulnerable to increased complications.

HISTORIQUE: Les données à grande échelle sur les complications de la chirurgie plastique font défaut. Une description des taux de référence et des résultats cliniques des patients permettrait de mieux déterminer comment améliorer les soins aux patients et réaliser des économies dans les systèmes de santé. Dans le présent article, les chercheurs recensent les complications les plus fréquentes en chirurgie plastique, dégagent les interventions aux taux de complication élevés et examinent les facteurs de risque prédictifs. MÉTHODOLOGIE: Les chercheurs ont réalisé une analyse rétrospective des données de chirurgie plastique tirées du programme national d'amélioration de la qualité chirurgicale de l'American College of Surgeons entre 2012 et 2016. Ils ont calculé les taux de complications de toute la cohorte et de chaque intervention recensée. Ils ont analysé les interventions microchirurgicales en sous-groupe, où ils ont utilisé des modèles de régression logistique multivariée pour déterminer les facteurs de risque d'infection des plaies opératoires (IPO) et de réopérations s'y rapportant. RÉSULTATS: Les chercheurs ont dénombré 108 303 patients qui avaient subi une intervention en chirurgie plastique, dont 6 264 (5,78 %) avaient souffert d'au moins une complication. Les réopérations (3,31 %), suivies des IPO (3,11 %) étaient les résultats à la plus forte incidence. Les cas de microchirurgie représentaient 6 148 (5,68 %) de toutes les occurrences, et 1211 (19,33 %) ont souffert d'au moins une complication. Tout comme dans l'ensemble de la cohorte, les réopérations (12,83 %) et les IPO (5,66 %) étaient des complications courantes. La plus longue durée de l'opération était un facteur de risque indépendant fréquent, prédicteur d'une réopération ou d'une IPO (p<0,001). Ainsi, 23,3 % des microchirurgies duraient plus de dix heures, ce qui s'associait à une plus forte augmentation du risque de réopération. CONCLUSIONS: Le taux de complications demeure relativement faible en chirurgie plastique, mais est significativement plus élevé en microchirurgie. La longue durée des opérations représente un facteur de risque courant. On pourrait explorer les approches à deux équipes et les opérations échelonnées, car une forte proportion des microchirurgies sont vulnérables à un accroissement des complications.

The relationship between preoperative nutritional state and adverse outcome following abdominal and thoracic surgery in children: Results from the NSQIP database.

INTRODUCTION: Anthropometric measurements can be used to define pediatric malnutrition. Our study aims to: (1) characterize the preoperative nutritional status of children undergoing abdominal or thoracic surgery, and (2) describe the associations between WHO-defined acute (stunting) and chronic (wasting) undernutrition (Z-scores <-2) and obesity (BMI Z-scores >+2) with 30-day postoperative outcomes. METHODS: We queried the Pediatric NSQIP Participant Use File and extracted data on patients' age 29days to 18years who underwent abdominal or thoracic procedures. Normalized anthropometric measures were calculated, including weight-for-height for <2years, BMI for ages ≥2years, and height for age. Logistic regression models were developed to assess nutritional outlier status as an independent predictor of postoperative outcome. RESULTS: 23,714 children (88% ≥2y) were evaluated. 4272 (18%) were obese, while 2640 (11.1%) and 904 (3.8%) were stunted and wasted, respectively, after controlling for gender, ASA/procedure/wound classification, preoperative steroid use, need for preoperative nutritional support, and obese children had higher odds of SSIs (OR 1.29, 95% CI 1.1-1.5, p=0.001), while stunted children were at increased risk of any 30-day postoperative complication (OR 1.16, 95% CI 1.0-1.3, p=0.036). CONCLUSION: Children who are stunted or obese are at increased risk of adverse outcome after abdominal or thoracic surgery. LEVEL OF EVIDENCE: III.

Impact of Multidisciplinary Standardization of Care for Gastroschisis: Treatment, Outcomes, and Cost.

BACKGROUND/PURPOSE: Elimination of unnecessary practice variation through standardization creates opportunities for improved outcomes and cost-effectiveness. A quality improvement (QI) initiative at our institution used evidence and consensus to standardize management of gastroschisis (GS) from birth to discharge. METHODS: An interdisciplinary team utilized best practice evidence and expert opinion to standardize GS care. Following stakeholder engagement and education, care standardization was implemented in September 2014. A comparative cohort study was conducted on consecutive patients treated before (n=33) and after (n=24) standardization. Demographic, treatment, and outcome measures were collected from a prospective GS registry. Direct costs were estimated, and protocol compliance was audited. RESULTS: BW, GA, and bowel injury severity were comparable between groups. Key practice changes were: closure technique (pre-88% primary fascial, post-83% umbilical cord flap; p<0.001), closure location (pre-97% OR, post-67% NICU; p<0.001), and GA avoidance (pre-0%, post-48%; p<0.001). Median post-closure ventilation days were shorter (pre-4, post-1; p<0.001), and SSI rates trended lower (pre-21%, post-8%; p=0.3) in the post-implementation group with no differences in TPN days or LOS. No significant difference was seen in average per-patient costs: pre-$85,725 ($29,974-221,061), post-$76,329 ($14,205-176,856). CONCLUSION: Care standardization for GS enables practice transformation, cost-effective outcome improvement, and supports an organizational culture dedicated to continuous improvement. LEVEL OF EVIDENCE: III.

What Is the Best Way to Measure Surgical Quality? Comparing the American College of Surgeons National Surgical Quality Improvement Program versus Traditional Morbidity and Mortality Conferences.

BACKGROUND: Morbidity and mortality conferences have played a traditional role in tracking complications. Recently, the American College of Surgeons National Surgical Quality Improvement Program Pediatrics (ACS NSQIP-P) has gained popularity as a risk-adjusted means of addressing quality assurance. The purpose of this article is to report an analysis of the two methodologies used within pediatric plastic surgery to determine the best way to manage quality. METHODS: ACS NSQIP-P and morbidity and mortality data were extracted for 2012 and 2013 at a quaternary care institution. Overall complication rates were compared statistically, segregated by type and severity, followed by a subset comparison of ACS NSQIP-P-eligible cases only. Concordance and discordance rates between the two methodologies were determined. RESULTS: One thousand two hundred sixty-one operations were performed in the study period. Only 51.4 percent of cases were ACS NSQIP-P eligible. The overall complication rates of ACS NSQIP-P (6.62 percent) and morbidity and mortality conferences (6.11 percent) were similar (p = 0.662). Comparing for only ACS NSQIP-P-eligible cases also yielded a similar rate (6.62 percent versus 5.71 percent; p = 0.503). Although different complications are tracked, the concordance rate for morbidity and mortality and ACS NSQIP-P was 35.1 percent and 32.5 percent, respectively. CONCLUSIONS: The ACS NSQIP-P database is able to accurately track complication rates similarly to morbidity and mortality conferences, although it samples only half of all procedures. Although both systems offer value, limitations exist, such as differences in definitions and purpose. Because of the rigor of the ACS NSQIP-P, we recommend that it be expanded to include currently excluded cases and an extension of the study interval.

ACS national surgical quality improvement program: targeting quality improvement in Canadian pediatric surgery.

PURPOSE: The pediatric NSQIP program is in the early stages of facilitated surgical quality improvement for children. The objective of this study is to describe the initial experience of the first Canadian Children's Hospital participant in this program. METHOD: Randomly sampled surgical cases from the "included" case list were abstracted into the ACS-NSQIP database. These surgical procedure-specific data incorporate patient risk factors, intraoperative details, and 30 day outcomes to generate annual reports which provide hierarchical ranking of participant hospitals according to their risk-adjusted outcomes. RESULTS: Our first risk-adjusted report identified local improvement opportunities based on our rates of surgical site infection (SSI) and urinary tract infection (UTI). We developed and implemented an engagement strategy for our stakeholders, performed literature reviews to identify practice variation, and conducted case control studies to understand local risk factors for our SSI/UTI occurrences. We have begun quality improvement activities targeting reduction in rates of SSI and UTI with our general surgery division and ward nurses, respectively. CONCLUSIONS: The NSQIP pediatric program provides high quality outcome data that can be used in support of quality improvement. This process requires multidisciplinary teamwork, systematic stakeholder engagement, clinical research methods and process improvement through engagement and culture change.
