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

Exploring strategies to enhance patient safety in spine surgery: a review

Patient safety is the foundation of spine surgery, where the intricate nature of spinal procedures and the unique risks involved call for exceptional diligence and comprehensive protocols. In this high-stakes field, developing and implementing rigorous safety protocols is not only vital for minimizing complications but also for achieving the best possible outcomes and strengthening the confidence patients have in their care team. Each patient entrusts their well-being to their surgical team. This trust underscores the responsibility healthcare providers have to prioritize safety at every stage. In spine surgery, thorough preoperative planning, clear communication during informed consent, and vigilant postoperative care are all crucial for creating a safe environment tailored to each patient's needs. A commitment to patient safety requires more than individual efforts; it calls for a coordinated, multidisciplinary approach where surgeons, nurses, anesthesiologists, and rehabilitation specialists work closely together. This collaboration ensures that each step of the patient's journey is aligned with best practices for safety and care. This review highlights the critical need for ongoing evaluation and refinement of safety protocols in spine surgery. As surgical techniques and technologies advance, and as patients' needs evolve, healthcare teams must remain responsive, cultivating a culture of safety that is both proactive and adaptable. Continuous investment in quality improvement and research is essential to fine-tune these protocols, ensuring they remain both relevant and effective in addressing the unique challenges of spine surgery. Prioritizing comprehensive safety measures goes beyond improving surgical outcomes; it plays a pivotal role in strengthening the trust and confidence patients have in their healthcare providers. By committing to these robust protocols, we reaffirm our dedication to patient-centered care, enhancing not only patient safety and recovery but also fostering a deeper faith in a healthcare system that places patient well-being at the forefront.

The influence of decreasing variable collection burden on hospital-level risk-adjustment

BACKGROUND

Risk-adjustment is a key feature of the American College of Surgeons National Surgical Quality Improvement Program-Pediatric (NSQIP-Ped). Risk-adjusted model variables require meticulous collection and periodic assessment. This study presents a method for eliminating superfluous variables using the congenital malformation (CM) predictor variable as an example.

METHODS

This retrospective cohort study used NSQIP-Ped data from January 1st to December 31st, 2019 from 141 hospitals to compare six risk-adjusted mortality and morbidity outcome models with and without CM as a predictor. Model performance was compared using C-index and Hosmer-Lemeshow (HL) statistics. Hospital-level performance was assessed by comparing changes in outlier statuses, adjusted quartile ranks, and overall hospital performance statuses between models with and without CM inclusion. Lastly, Pearson correlation analysis was performed on log-transformed ORs between models.

RESULTS

Model performance was similar with removal of CM as a predictor. The difference between C-index statistics was minimal (≤ 0.002). Graphical representations of model HL-statistics with and without CM showed considerable overlap and only one model attained significance, indicating minimally decreased performance (P = 0.058 with CM; P = 0.044 without CM). Regarding hospital-level performance, minimal changes in the number and list of hospitals assigned to each outlier status, adjusted quartile rank, and overall hospital performance status were observed when CM was removed. Strong correlation between log-transformed ORs was observed (r ≥ 0.993).

CONCLUSIONS

Removal of CM from NSQIP-Ped has minimal effect on risk-adjusted outcome modelling. Similar efforts may help balance optimal data collection burdens without sacrificing highly valued risk-adjustment in the future.

Prevention of Surgical Site Infections in Neonates and Children: Non-Pharmacological Measures of Prevention

A surgical site infection (SSI) is an infection that occurs in the incision created by an invasive surgical procedure. Although most infections are treatable with antibiotics, SSIs remain a significant cause of morbidity and mortality after surgery and have a significant economic impact on health systems. Preventive measures are essential to decrease the incidence of SSIs and antibiotic abuse, but data in the literature regarding risk factors for SSIs in the pediatric age group are scarce, and current guidelines for the prevention of the risk of developing SSIs are mainly focused on the adult population. This document describes the current knowledge on risk factors for SSIs in neonates and children undergoing surgery and has the purpose of providing guidance to health care professionals for the prevention of SSIs in this population. Our aim is to consider the possible non-pharmacological measures that can be adopted to prevent SSIs. To our knowledge, this is the first study to provide recommendations based on a careful review of the available scientific evidence for the non-pharmacological prevention of SSIs in neonates and children. The specific scenarios developed are intended to guide the healthcare professional in practice to ensure standardized management of the neonatal and pediatric patients, decrease the incidence of SSIs and reduce antibiotic abuse.

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.

Analysis of risk factors for morbidity in children undergoing the Kasai procedure for biliary atresia

OBJECTIVE

To evaluate the perioperative risk factors for 30-day complications of the Kasai procedure in a large, cross-institutional, modern dataset.

STUDY DESIGN

The 2012-2015 National Surgical Quality Improvement Program Pediatric database was used to identify patients undergoing the Kasai procedure. Patients' characteristics were compared by perioperative blood transfusions and 30-day outcomes, including complications, reoperations, and readmissions. Multivariable logistic regression was used to identify risk factors predictive of outcomes. Propensity matching was performed for perioperative blood transfusions to evaluate its effect on outcomes.

RESULTS

190 children were included with average age of 62 days. Major cardiac risk factors were seen in 6.3%. Perioperative blood transfusions occurred in 32.1%. The 30-day post-operative complication rate was 15.8%, reoperation 6.8%, and readmission 15.3%. After multivariate analysis, perioperative blood transfusions (OR 3.94; p < 0.01) and major cardiac risk factors (OR 7.82; p < 0.01) were found to increase the risk of a complication. Perioperative blood transfusion (OR 4.71; p = 0.01) was associated with an increased risk of reoperation. Readmission risk was increased by prematurity (OR 3.88; p = 0.04) and 30-day complication event (OR 4.09; p = 0.01). After propensity matching, perioperative blood transfusion was associated with an increase in complications (p < 0.01) and length of stay (p < 0.01).

CONCLUSION

Major cardiac risk factors and perioperative blood transfusions increase the risk of post-operative complications in children undergoing the Kasai procedure. Further research is warranted in the perioperative use of blood transfusions in this population.

Review of an emergency general surgery process improvement program at a verified military trauma center

INTRODUCTION

Decreasing combat-based admissions to our military facility have made it difficult to maintain a robust trauma process improvement (PI) program. Since emergency general surgery (EGS) and trauma patients share similarities, we merged the care of our EGS and trauma patients into one acute care surgery (ACS) team. An EGS PI program was developed based on trauma PI principles to facilitate continued identification of opportunities for improvement despite our decline in trauma admissions. Analysis of the first 18 months of combined ACS PI data is presented.

METHODS

EGS registry inclusion criteria was based on published Association for the Surgery of Trauma's recommendations. Program components and PI categories were based on our existing trauma PI program. Dedicated coordinators actively reviewed and cataloged patient care and outcomes. Deviations from standard practice patterns, unplanned interventions, and other complications were abstracted, categorized, and evaluated through levels of review similar to accepted trauma PI principles. Data for the first six quarters were collated and trends were analyzed.

RESULTS

Over 18 months, 696 EGS patients met registry inclusion criteria, with 468 patients (67%) undergoing operative intervention. Over the same time, 353 trauma patients were admitted with 158 undergoing operative intervention (56.4%). Of the 696 EGS patients and 353 trauma patients, 226 (32%) and 243 (69%) PI events were identified, respectively. Common events included unplanned therapies, re-admissions, and unplanned ICU admissions. Based on analysis of all events, four new areas for improvement initiatives were identified. Results of these initiatives included implementation of a multi-disciplinary EGS PI committee, consensus protocols, and departmental and hospital-wide actions.

CONCLUSION

In an 18-month period, integration of our EGS patients into a novel, combined ACS PI program facilitated recognition of an additional 226 PI events and provided a substrate for continued improvements in patient care.

Understanding readmissions in children undergoing surgery: A pediatric NSQIP analysis

BACKGROUND

Readmission is increasingly being utilized as an important clinical outcome and measure of hospital quality. Our aim was to delineate rates, risk factors, and reasons for unplanned readmission in pediatric surgery.

MATERIALS AND METHODS

Retrospective review of pediatric patients (n=130,274) undergoing surgery (2013-2014) at hospitals enrolled in the Pediatric National Surgical Quality Improvement Program (NSQIP-P) was performed. Logistic regression was used to model factors associated with unplanned 30-day readmission. Reasons for readmission were reviewed to determine the most common causes of readmission.

RESULTS

There were 6059 (n=4.7%) readmitted children within 30days of the index operation. Of these, 5041 (n=3.9%) were unplanned, with readmission rates ranging from 1.3% in plastic surgery to 5.2% in general pediatric surgery, and 10.8% in neurosurgery. Unplanned readmissions were associated with emergent status, comorbidities, and the occurrence of pre- or postdischarge postoperative complications. Overall, the most common causes for readmission were surgical site infections (23.9%), ileus/obstruction/gastrointestinal (16.8%), respiratory (8.6%), graft/implant/device-related (8.1%), neurologic (7.0%), or pain (5.8%). Median time from discharge to readmission was 8days (IQR: 3-14days). Reasons for readmission, time until readmission, and need for reoperative procedure (overall 28%, n=1414) varied between surgical specialties.

CONCLUSION

The reasons for readmission in children undergoing surgery are complex, varied, and influenced by patient characteristics and postoperative complications. These data inform risk-stratification for readmission in pediatric surgical populations, and help to identify potential areas for targeted interventions to improve quality. They also highlight the importance of accounting for case-mix in the interpretation of hospital readmission rates.

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.

Safety and postoperative adverse events in pediatric airway reconstruction: Analysis of ACS-NSQIP-P 30-day outcomes

OBJECTIVES

Prior research has shown that airway reconstructive procedures comprise significant composite morbidity compared to the whole of pediatric otolaryngologic cases evaluated in the American College of Surgeon's National Surgery Quality Improvement Program-Pediatric (ACS-NSQIP-P) platform. We describe postoperative sequelae of pediatric airway reconstructive procedures and identify predictive factors for adverse events.

METHODS

Current procedural terminology (CPT) codes were used to identify children undergoing included procedures in the 2012 to 2014 ACS-NSQIP-P public use files (PUF). Targeted variables included patient demographics and 30-day postoperative events (reoperation, readmission, and complications). Event rates were determined and compared within subgroups. Multivariate logistic regression was performed to identify predictive factors for major adverse events.

RESULTS

In 3 years of PUF data (183,283 total cases), 198 cases (0.11%) were airway reconstructive procedures. The most common was laryngoplasty (CPT 31580, 31582; n = 111, 56.1%), followed by cervical tracheoplasty (CPT 31750; n = 47, 23.7%), tracheal resection (CPT 31780; n = 24, 12.1%), and cricoid split (CPT 31587, n = 16, 8.1%). There were 131 premature children (66.2%) and 94 children (47.5%) with history of bronchopulmonary dysplasia. Thirty-day postoperative sequelae included readmissions (n = 42, 21.2%), complications (n = 27, 13.6%), and reoperations (n = 14, 7.1%). On univariate analysis, children less than 3 years of age were more likely to undergo an unplanned reoperation. There were no significant predictive factors for readmission or complication. On multivariate analysis, there was a trend toward higher rates of unplanned reoperations in children less than 3 years of age.

CONCLUSION

The 30-day adverse event rate in pediatric airway surgery is high, with no identifiable predictors noted in the analysis of these data. Findings imply that systematic collection of variables and outcomes specific to pediatric airway surgery, in addition to standard NSQIP workflow, will be essential for NSQIP-P to truly effect quality improvement in these high-risk procedures.

Race and 30-Day Morbidity in Pediatric Urologic Surgery

BACKGROUND AND OBJECTIVE

Quality improvement in surgery involves identifying patients at high risk for postoperative complications. We sought to assess the impact of race and procedure type on 30-day surgical morbidity in pediatric urology.

METHODS

The National Surgical Quality Improvement Program-Pediatrics (NSQIP-P) is a prospective registry of surgical cases from 50 and 56 pediatric hospitals in 2012 and 2013, respectively. We performed a cohort study of children followed in NSQIP-P who underwent urologic surgery. Forty unique operations were stratified into 6 clinically related procedure groups: ureteral, testicular, renal, urinary diversion, penile and urethral, or bladder procedures. Outcomes were 3 different composite measures of 30-day morbidity. Primary predictors were patient race and procedural group. Multivariate logistic regression was used to identify associations between race, procedure type, and postoperative morbidity.

RESULTS

Of 114 395 patients in the NSQIP-P cohort, 11 791 underwent pediatric urologic procedures. Overall 30-day complication rate was 5.9% and was higher in bladder and urinary diversion procedures. On multivariate analyses, non-Hispanic black compared with non-Hispanic white children had higher odds of 30-day overall complications (odds ratio 1.34; 95% confidence interval, 1.03-1.74) and 30-day hospital-acquired infection (odds ratio 1.54; 95% confidence interval, 1.08-2.20). Bladder and urinary diversion procedures relative to testicular procedures had significantly higher odds of surgical morbidity across all composite outcome measures.

CONCLUSIONS

Black race and bladder and urinary diversion operations were significantly associated with 30-day surgical morbidity. Future efforts should identify processes of care that decrease postoperative morbidity among children.

Measuring Surgical Site Infections in Children: Comparing Clinical, Electronic, and Administrative Data

BACKGROUND

Surgical site infections (SSIs) are an important end point and measure of quality of care. Surgical site infections can be identified using clinical registries, electronic surveillance, and administrative claims data. This study compared measurements of SSIs using these 3 different methods and estimated their implication for health care costs.

STUDY DESIGN

Data were obtained from 5,476 surgical patients treated at a single academic children's hospital (January 1, 2010 through August 31, 2014). Surgical site infections within 30 days were identified using a clinical registry in the NSQIP Pediatric, an electronic surveillance method (Nosocomial Infection Marker; MedMined), and billing claims. Infection rates, diagnostic characteristics, and attributable costs were estimated for each of the 3 measures of SSI.

RESULTS

Surgical site infections were observed in 2.24% of patients per NSQIP Pediatric definitions, 0.99% of patients per the Nosocomial Infection Marker, and 2.34% per billing claims definitions. Using NSQIP Pediatric as the clinical reference, Nosocomial Infection Marker had a sensitivity of 31.7% and positive predictive value of 72.2%, and billing claims had a sensitivity of 48.0% and positive predictive value of 46.1% for detection of an SSI. Nosocomial Infection Marker and billing claims overestimated the costs of SSIs by 108% and 41%, respectively.

CONCLUSIONS

There is poor correlation among SSIs measured using electronic surveillance, administrative claims, and clinically derived measures of SSI in the pediatric surgical population. Although these measures might be more convenient, clinically derived data, such as NSQIP Pediatric, may provide a more appropriate quality metric to estimate the postoperative burden of SSIs in children.

Subspecialization within pediatric surgical groups in North America

PURPOSE

The purpose of this study was to assess the current status of subspecialization in North American pediatric surgical practices and to evaluate factors associated with subspecialization.

METHODS

A survey was sent to each pediatric surgical practice in the United States and Canada. For each of 44 operation types, ranging in complexity and volume, the respondents chose one of the following responses: 1. everyone does the operation; 2. group policy--only some surgeons do the operation; 3. group policy--anyone can do it but mentorship required; 4. only some do it due to referral patterns; 5. no one in the group does it. Association of various factors with degree of subspecialization was analyzed using nonparametric statistics with p<0.05 considered significant.

RESULTS

Response rate was 70%. There was significant variability in subspecialization among groups. Factors found to be significantly associated with increased subspecialization included free-standing children's hospitals, pediatric surgery training programs, higher number of surgeons, higher case volume, and greater volume of tertiary/quaternary cases.

CONCLUSIONS

There is wide variation in the degree of subspecialization among North American pediatric surgery practices. These data will help to inform ongoing debate around strategies that may be useful in optimizing pediatric surgical care and patient outcomes in the future.

Improving surgical care for children through multicenter registries and QI collaboratives

The role of the healthcare organization is shifting and must overcome the challenges of fragmented, costly care, and lack of evidence in practice, to reduce cost, ensure quality, and deliver high-value care. Notable gaps exist within the expected quality and delivery of pediatric healthcare, necessitating a change in the role of the healthcare organization. To realize these goals, the use of collaborative networks that leverage massive datasets to provide information for the development of learning healthcare systems will become increasingly necessary as efforts are made to narrow the gap in healthcare quality for children. By building upon the lessons learned from early collaborative efforts and other industries, operationalizing new technologies, encouraging clinical-community partnerships, and improving performance through transparent pursuit of meaningful goals, pediatric surgery can increase the adoption of best practices by developing collaborative networks that provide evidence-based clinical decision support and accelerate progress toward a new culture of delivering high-quality, high-value, and evidenced-based pediatric surgical care.

Innovating for quality and value: Utilizing national quality improvement programs to identify opportunities for responsible surgical innovation

Innovation in surgical techniques, technology, and care processes are essential for improving the care and outcomes of surgical patients, including children. The time and cost associated with surgical innovation can be significant, and unless it leads to improvements in outcome at equivalent or lower costs, it adds little or no value from the perspective of the patients, and decreases the overall resources available to our already financially constrained healthcare system. The emergence of a safety and quality mandate in surgery, and the development of the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) allow needs-based surgical care innovation which leads to value-based improvement in care. In addition to general and procedure-specific clinical outcomes, surgeons should consider the measurement of quality from the patients' perspective. To this end, the integration of validated Patient Reported Outcome Measures (PROMs) into actionable, benchmarked institutional outcomes reporting has the potential to facilitate quality improvement in process, treatment and technology that optimizes value for our patients and health system.

Safety and postoperative adverse events in pediatric otologic surgery: analysis of American College of Surgeons NSQIP-P 30-Day outcomes

OBJECTIVES

Describe safety and postoperative sequelae of pediatric otologic surgery and identify predictive factors for postoperative events.

STUDY DESIGN

Retrospective cohort study of the American College of Surgeons National Surgery Quality Improvement Program-Pediatric (NSQIP-P) database.

SETTING

Data pooled from the 2012 NSQIP-P public use file (50 institutions).

SUBJECTS AND METHODS

Current procedural terminology codes were used to identify children who underwent otologic surgery. Variables of interest included demographics and 30-day postoperative events grouped as reoperation, readmission, and complication. Event rates were determined and prevalence of events compared by procedure type and within patient subgroups according to chi-square analysis. Multivariate logistic regression evaluated predictive factors for postoperative events.

RESULTS

Of 37,319 pediatric operations, 2556 (6.8%) were otologic procedures. The most common procedure was tympanoplasty (n = 893, 34.9%), followed by myringoplasty (n = 741, 30.0%), cochlear implantation (n = 464, 18.2%), and tympanomastoidectomy (n = 458, 17.9%). There were 9 reoperations (0.4%), 32 readmissions (1.3%), and 18 complications (0.7%). Children undergoing tympanomastoidectomy or cochlear implantation were more likely to be readmitted irrespective of other factors (odds ratio = 5.5, P = .010; odds ratio = 3.5, P = .083). Children <3 years old were 4 times more likely to be readmitted than older children (odds ratio = 4.4, P < .001).

CONCLUSION

Pediatric otologic procedures are common and have low rates of global 30-day postoperative events. Tympanomastoidectomy and cochlear implantation have the highest risk of 30-day readmission. Young children (<3 years) are more likely to be readmitted following these procedures. Further optimization of the NSQIP-P to include specialty and procedure-specific variables is necessary to assess complete, actionable outcomes of pediatric otologic surgery, however the present study provides a foundation to build upon for safety and quality improvement initiatives in pediatric otology.
