Enhancing recovery in pediatric surgery: a review of the literature

BACKGROUND Enhanced recovery after surgery (ERAS), guidelines entail a strategy of perioperative management proven to hasten postoperative recovery and reduce complications in adult populations. Relatively few studies have investigated the applicability of this paradigm to pediatric populations. Our objective was to perform a systematic review of existing evidence regarding the use and efficacy of enhanced recovery protocols (ERPs) in the pediatric population. MATERIALS AND METHODS Data were collected through a PubMed/MEDLINE literature search. Study eligibility criteria included a pediatric population and implementation of at least four components of published ERAS Society recommendations. RESULTS One retrospective and four prospective cohort studies evaluating children undergoing gastrointestinal, urologic, and thoracic surgeries were identified. The overall quality of reporting was fair with few studies acknowledging limitations and bias and inconsistent outcome reporting. Studies included six or fewer interventions compared to 20 recommended interventions in most adult ERAS Society guidelines. None of the studies were well controlled. Nevertheless, these studies suggest that ERPs applied to the appropriate pediatric surgical populations may be associated with decreased length of stay, decreased narcotic use, and no detectable increase in complications. CONCLUSIONS There is a paucity of high-quality literature evaluating implementation of ERPs in pediatric populations. The limited literature available indicates that ERPs would be safe and potentially effective. More studies are needed to assess the efficacy of ERPs in pediatric surgery.

Implementation of an enhanced recovery protocol in pediatric colorectal surgery

PURPOSE Enhanced recovery protocols (ERPs) have been shown to improve outcomes in adult surgical populations. Our purpose was to compare outcomes before and after implementation of an ERP in children undergoing elective colorectal surgery. METHODS A pediatric-specific colorectal ERP was developed and implemented at a single center starting in January 2015. A retrospective review was performed including 43 patients in the pre-ERP period (2012-2014) and 36 patients in the post-ERP period (2015-2016). Outcomes of interest included number of ERP interventions received, length of stay (LOS), complications, and readmissions. RESULTS The median number of ERP interventions received per patient increased from 5 to 11 from 2012 to 2016. The median LOS decreased from 5days to 3days in the post-ERP period (p=0.01). We observed a simultaneous decrease in median time to regular diet, mean dose of narcotics, and mean volume of intraoperative fluids (p<0.001). The complication rate (21% vs. 17%, p=0.85) and 30-day readmission rate (23% vs. 11%, p=0.63) were not significantly different in the pre- and post-ERP periods. CONCLUSIONS Implementation of a pediatric-specific ERP in children undergoing colorectal surgery is feasible, safe and may lead to improved outcomes. Further experience may highlight other opportunities for increased compliance and improved care. LEVEL OF EVIDENCE Treatment Study. Level III.

Challenge of balancing duration of stay and readmissions in children's operation

Background. Surgeons balance competing interests of minimizing duration of stay with readmissions. Complications that occur early after discharge often result in readmissions. This study examines the relationship between duration of stay, timing of complications, and readmission risk. Methods. Cases from the 2012–2014 National Surgical Quality Improvement Project—Pediatric were organized into 30 procedural groups. Procedures where duration of stay approximated the median day of complication were identified. A theoretical model was applied to minimize readmissions by extending duration of stay. Results. From 30 procedure groups, 3 were identified where duration of stay approximated median day of compilations: complicated appendectomy, antireflux operation, and abdominal operation without bowel resection. The complicated appendectomy readmission rate drops from 12.2% to 8.2%, increasing duration of stay from 3 to 8 days at the cost of 16,428 additional hospital days among 4,740 patients (3.5 days/patient). Readmission optimization tapers after duration of stay of 8 days. Similar findings were observed for antireflux operation and abdominal operation without bowel resection with readmission optimization at duration of stay of 5 days (2.6 days/patient) and 7 days (5.3 days/patient), respectively. Conclusion. Our theoretical model aimed at balancing readmissions by extending duration of stay to capture early complications results in a substantial increase in hospital days illustrating the conflict between competing quality metrics and limited resources.

Variation in Preoperative Testing and Antireflux Surgery in Infants

By using the PHIS database, this study characterizes national variation in diagnostic testing and surgical utilization for infants with GERD. BACKGROUND: Despite the availability of objective tests, gastroesophageal reflux disease (GERD) diagnosis and management in infants remains controversial and highly variable. Our purpose was to characterize national variation in diagnostic testing and surgical utilization for infants with GERD. METHODS: Using the Pediatric Health Information System, we identified infants <1 year old diagnosed with GERD between January 2011 and March 2015. Outcomes included progression to antireflux surgery (ARS) and use of relevant diagnostic testing. By using adjusted generalized linear mixed models, we compared facility-level ARS utilization. RESULTS: Of 5 299 943 infants, 149 190 had GERD (2.9%), and 4518 (3.0%) of those patients underwent ARS. Although annual rates of GERD and ARS decreased, there was a wide range of GERD diagnoses (1.8%–6.2%) and utilization of ARS (0.2%–11.2%). Facilities varied in the use of laparoscopic versus open ARS (mean: 66%, range: 23%–97%). Variation in facility-level ARS rates persisted after adjustment. Overall 3.8% of patients underwent diagnostic testing, whereas 22.8% of ARS patients underwent diagnostic testing. The proportion of surgeries done laparoscopically was independently associated with ARS utilization (odds ratio: 1.57; 95% confidence interval: 1.21–2.02). Facility-level utilization of diagnostics (P > .1) and prevalence of GERD (P > .1) were not associated with utilization of ARS. CONCLUSIONS: There is notable variation in the overall utilization of ARS and in the surgical and diagnostic approach in infants with GERD. Fewer than 4% of infants with GERD undergo diagnostic testing. This variation in care merits development of consensus guidelines and further research.

Appropriateness of a pediatric-specific enhanced recovery protocol using a modified Delphi process and multidisciplinary expert panel

PURPOSE Despite Enhanced Recovery After Surgery (ERAS) protocols demonstrating improved outcomes in a wide variety of adult surgical populations, these protocols are infrequently and inconsistently being used in pediatric surgery. Our purpose was to develop a pediatric-specific ERAS protocol for use in adolescents undergoing elective intestinal procedures. METHODS A modified Delphi process including extensive literature review, iterative rounds of surveys, and expert panel discussions was used to establish ERAS elements that would be appropriate for children. The 16-member multidisciplinary expert panel included surgeons, gastroenterologists, anesthesiologists, nursing, and patient/family representatives. RESULTS Building upon a national survey of surgeons in which 14 of 21 adult ERAS elements were considered acceptable for use in children, the 7 more contentious elements were investigated using the modified Delphi process. In final ranking, 5 of the 7 controversial elements were deemed appropriate for inclusion in a pediatric ERAS protocol. Routine use of insulin to treat hyperglycemia and avoidance of mechanical bowel preparation were not included in the final recommendations. CONCLUSIONS Using a modified Delphi process, we have defined an appropriate ERAS protocol comprised of 19 elements for use in adolescents undergoing elective intestinal surgery. Prospective validation studies of ERAS protocols in children are needed. LEVEL OF EVIDENCE Level V, Expert opinion.

Defining the association between operative time and outcomes in children's surgery

INTRODUCTION Prolonged operative time (OT) is considered a reflection of procedural complexity and may be associated with poor outcomes. Our purpose was to explore the association between prolonged OT and complications in childrens surgery. METHODS 182,857 cases from the 2012-2014 NSQIP-Pediatric were organized into 33 groups. OT for each group was analyzed by quartile, and regression models were used to determine the relationship between prolonged OT and complications. RESULTS Variations in OT existed for both short and long procedures. Cases in the longest quartile had twice the odds of postoperative complications after adjusting for age, sex and BMI (OR 1.85; 95% CI 1.78-1.91). Procedure-specific prolonged OT was associated with postoperative complications for the majority (85%) of procedural groupings. Prolonged OT was associated with minor complications in gynecologic (OR 4.17; 95% CI 2.19-7.96), urologic (OR 2.88; 95% CI 2.40-3.44), and appendix procedures (OR 2.88; 95% CI 2.49-3.34). There were increased odds of major complications in foregut (OR 6.56; 95% CI 4.99-8.64), gynecologic (OR 3.07; 95% CI 1.84-5.13), and spine procedures (OR 2.99; 95% CI 2.57-3.28). CONCLUSIONS Prolonged OT is associated with increased odds of postoperative complications across a spectrum of childrens surgical procedures. Factors contributing to prolonged OT merit further investigation and may serve as a target for future quality improvement. LEVEL OF EVIDENCE Level III.

Improving ultrasound for appendicitis through standardized reporting of secondary signs

OBJECTIVE Our aim was to implement a standardized US report that included secondary signs of appendicitis (SS) to facilitate accurate diagnosis of appendicitis and decrease the use of computed tomography (CT) and admissions for observation. METHODS A multidisciplinary team implemented a quality improvement (QI) intervention in the form of a standardized US report and provided stakeholders with monthly feedback. Outcomes including report compliance, CT use, and observation admissions were compared pretemplate and posttemplate. RESULTS We identified 387 patients in the pretemplate period and 483 patients in the posttemplate period. In the posttemplate period, the reporting of SS increased from 5.4% to 79.5% (p<0.001). Despite lower rates of appendix visualization (43.9% to 32.7%, p<0.001) with US, overall CT use (8.5% vs 7.0%, p=0.41) and the negative appendectomy rate remained stable (1.0% vs 1.0%, p=1.0). CT utilization for patients with an equivocal ultrasound and SS present decreased (36.4% vs 8.9%, p=0.002) and admissions for observations decreased (21.5% vs 15.3%, p=0.02). Test characteristics of RLQ US for appendicitis also improved in the posttemplate period. CONCLUSION A focused QI initiative led to high compliance rates of utilizing the standardized US report and resulted in lower CT use and fewer admissions for observation.

Parent reported long-term quality of life outcomes in children after congenital diaphragmatic hernia repair

PURPOSE The aim of this study was to determine long-term outcomes for congenital diaphragmatic hernia (CDH) patients including quality of life (QoL), symptom burden, reoperation rates, and health status. METHODS A chart review and phone QoL survey were performed for patients who underwent CDH repair between 2007 and 2014 at a tertiary free-standing childrens hospital. Comprehensive outcomes were collected including subsequent operations and health status. Associations with QoL were tested using Wilcoxon Rank-Sum tests and Pearson correlation coefficients. RESULTS Of 102 CDH patients identified, 46 (45.1%) patient guardians agreed to participate with mean patient age of 5.8 (SD, 2.2) years at time of follow-up. Median PedsQLTM and PedsQLTM Gastrointestinal scores were 91.8 (IQR, 84.8-95.8) and 95.8 (IQR, 93.0-98.2), out of 100. Thoracoscopic repair was associated with higher PedsQLTM scores while defects with an intrathoracic stomach were associated with increased gas and bloating. No difference in QoL was found when comparing defect side, patch vs primary repair, prenatal diagnosis, extracorporeal membrane oxygenation, or recurrence. Older age weakly correlated with worse school functioning and heartburn. CONCLUSION Children with CDH have reassuring QoL scores. Given the correlation between older age and poor school function, longer follow-up of patients with CDH may be warranted. LEVEL OF EVIDENCE III (Retrospective comparative study).

Exploring regional variability in utilization of antireflux surgery in children

BACKGROUND There is significant variation surrounding the indications, surgical approaches, and outcomes for children undergoing antireflux procedures (ARPs) resulting in geographic variation of care. Our purpose was to quantify this geographic variation in the utilization of ARPs in children. METHODS A cross-sectional analysis of the 2009 Kids Inpatient Database was performed to identify patients with gastroesophageal reflux disease or associated diagnoses. Regional surgical utilization rates were determined, and a mixed effects model was used to identify factors associated with the use of ARPs. RESULTS Of the 148,959 patients with a diagnosis of interest, 4848 (3.3%) underwent an ARP with 2376 (49%) undergoing a laparoscopic procedure. The Northeast (2.0%) and Midwest (2.2%) had the lowest overall utilization of surgery, compared with the South (3.3%) and West (3.4%). After adjustment for age, case-mix, and surgical approach, variation persisted with the West and the South demonstrating almost two times the odds of undergoing an ARP compared with the Northeast. Surgical utilization rates are independent of state-level volume with some of the highest case volume states having surgical utilization rates below the national rate. In the West, the use of laparoscopy correlated with overall utilization of surgery, whereas surgical approach was not correlated with ARP use in the South. CONCLUSIONS Significant regional variation in ARP utilization exists that cannot be explained entirely by differences in patient age, race/ethnicity, case-mix, and surgical approach. In order to decrease variation in care, further research is warranted to establish consensus guidelines regarding indications for the use ARPs for children.

Cost comparison of initial lobectomy versus fine-needle aspiration for diagnostic workup of thyroid nodules in children

BACKGROUND Though uncommon in children, pediatric thyroid nodules carry a higher risk of malignancy than adult nodules. While fine-needle aspiration (FNA) has been well established as the initial diagnostic test in adults, it has been more slowly adopted in children. The purpose of this study was to examine the comparative cost of FNA versus initial diagnostic lobectomy (DL) in the pediatric patient with an ultrasound-confirmed thyroid nodule. METHODS A decision tree model was created using an adolescent with an asymptomatic thyroid nodule as the reference case. Probabilities were defined based on review of the pediatric and adult literature. Costs were determined from previous literature and the publicly available Medicare physician fee schedule. Tornado plot and sensitivity analyses were performed to assess sources of cost variation. RESULTS Using decision analysis, FNA was less costly than DL with an estimated cost of
