ABSTRACT
OBJECTIVE: To develop a severity-adjusted, hospital-level benchmarking comparative performance report for postoperative organ space infection and antibiotic utilization in children with complicated appendicitis. BACKGROUND: No benchmarking data exist to aid hospitals in identifying and prioritizing opportunities for infection prevention or antimicrobial stewardship in children with complicated appendicitis. METHODS: This was a multicenter cohort study using NSQIP-Pediatric data from 16 hospitals participating in a regional research consortium, augmented with antibiotic utilization data obtained through supplemental chart review. Children with complicated appendicitis who underwent appendectomy from 07/01/2015 to 06/30/2020 were included. Thirty-day postoperative OSI rates and cumulative antibiotic utilization were compared between hospitals using observed-to-expected (O/E) ratios after adjusting for disease severity using mixed effects models. Hospitals were considered outliers if the 95% confidence interval for O/E ratios did not include 1.0. RESULTS: 1790 patients were included. Overall, the OSI rate was 15.6% (hospital range: 2.6-39.4%) and median cumulative antibiotic utilization was 9.0 days (range: 3.0-13.0). Across hospitals, adjusted O/E ratios ranged 5.7-fold for OSI (0.49-2.80, P=0.03) and 2.4-fold for antibiotic utilization (0.59-1.45, P<0.01). Three (19%) hospitals were outliers for OSI (1 high and 2 low performers), and eight (50%) were outliers for antibiotic utilization (5 high and 3 low utilizers). Ten (63%) hospitals were identified as outliers in one or both measures. CONCLUSIONS: A comparative performance benchmarking report may help hospitals identify and prioritize quality improvement opportunities for infection prevention and antimicrobial stewardship, as well as identify exemplar performers for dissemination of best practices.
ABSTRACT
OBJECTIVE: To evaluate whether redosing antibiotics within an hour of incision is associated with a reduction in incisional surgical site infection (iSSI) in children with appendicitis. BACKGROUND: Existing data remain conflicting as to whether children with appendicitis receiving antibiotics at diagnosis benefit from antibiotic redosing before incision. METHODS: This was a multicenter retrospective cohort study using data from the Pediatric National Surgical Quality Improvement Program augmented with antibiotic utilization and operative report data obtained though supplemental chart review. Children undergoing appendectomy at 14 hospitals participating in the Eastern Pediatric Surgery Network from July 2016 to June 2020 who received antibiotics upon diagnosis of appendicitis between 1 and 6 hours before incision were included. Multivariable logistic regression was used to compare odds of iSSI in those who were and were not redosed with antibiotics within 1 hour of incision, adjusting for patient demographics, disease severity, antibiotic agents, and hospital-level clustering of events. RESULTS: A total of 3533 children from 14 hospitals were included. Overall, 46.5% were redosed (hospital range: 1.8%-94.4%, P <0.001) and iSSI rates were similar between groups [redosed: 1.2% vs non-redosed: 1.3%; odds ratio (OR) 0.84, (95%,CI, 0.39-1.83)]. In subgroup analyses, redosing was associated with lower iSSI rates when cefoxitin was used as the initial antibiotic (redosed: 1.0% vs nonredosed: 2.5%; OR: 0.38, (95% CI, 0.17-0.84)], but no benefit was found with other antibiotic regimens, longer periods between initial antibiotic administration and incision, or with increased disease severity. CONCLUSIONS: Redosing of antibiotics within 1 hour of incision in children who received their initial dose within 6 hours of incision was not associated with reduction in risk of incisional site infection unless cefoxitin was used as the initial antibiotic.

OBJECTIVE: To compare rates of postoperative drainage and culture profiles in children with complicated appendicitis treated with the two most common antibiotic regimens with and without antipseudomonal activity (piperacillin-tazobactam [PT] and ceftriaxone with metronidazole [CM]). SUMMARY OF BACKGROUND DATA: Variation in use of antipseudomonal antibiotics has been driven by a paucity of multicenter data reporting clinically relevant, culture-based outcomes. METHODS: Retrospective cohort study of patients with complicated appendicitis (7/2015-6/2020) using NSQIP-Pediatric data from 15 hospitals participating in a regional research consortium. Operative report details, antibiotic utilization, and culture data were obtained through supplemental chart review. Rates of 30-day postoperative drainage and organism-specific culture positivity were compared between groups using mixed effects regression to adjust for clustering after propensity matching on measures of disease severity. RESULTS: 1002 children met criteria for matching (58.9% received CM and 41.1% received PT). In the matched sample of 778 patients, children treated with PT had similar rates of drainage overall (PT: 11.8%, CM: 12.1%; OR 1.44 [OR:0.71-2.94]) and higher rates of drainage associated with growth of any organism (PT: 7.7%, CM: 4.6%; OR 2.41 [95%CI:1.08-5.39]) and Escherichia coli (PT: 4.6%, CM: 1.8%; OR 3.42 [95%CI:1.07-10.92]) compared to treatment with CM. Rates were similar between groups for drainage associated with multiple organisms (PT: 2.6%, CM: 1.5%; OR 3.81 [95%CI:0.96-15.08]) and Pseudomonas (PT: 1.0%, CM: 1.3%; OR 3.42 [95%CI:0.55-21.28]). CONCLUSIONS AND RELEVANCE: Use of antipseudomonal antibiotics is not associated with lower rates of postoperative drainage procedures or more favorable culture profiles in children with complicated appendicitis.
ABSTRACT
INTRODUCTION: The American Association of Pediatrics released guidelines in 2019 recommending delay of surgical referral in children with asymptomatic umbilical hernias until 4-5 y of age. The purpose of this study was to assess contemporary rates of potentially avoidable referrals in this cohort of children, and to assess whether rates have decreased following guideline release. METHODS: Retrospective analysis of umbilical hernias referrals evaluated at a single pediatric surgery clinic from October 2014 to August 2021. Potentially avoidable referrals (PAR) were defined as asymptomatic, non-enlarging umbilical hernia referrals in a child 3 y of age or younger without a history of incarceration. Referral indication, disposition following clinic visit, and rates of PAR were compared before and after guideline release. RESULTS: A total of 803 umbilical hernia referrals were evaluated, of which 48% were in children 3 y of age or younger at time of evaluation ("early" referrals). 33% of all referrals and 68% of early referrals were categorized as a PAR, and rates were similar before and after guideline release (all referrals: 32% versus 33%, P = 0.94; early referrals: 68% versus 67%, P = 0.94). Of the 333 early referrals who were managed expectantly per guideline recommendations, 2 (0.6%) developed incarceration which was managed with successful reduction and interval repair. CONCLUSIONS: One-third of all referrals for umbilical hernia evaluation are potentially avoidable, and this rate did not change following release of American Academy of Pediatrics guidelines. Aligning expectations between surgeons and referring providers through improved education and guideline dissemination may reduce avoidable visits, lost caregiver productivity, and exposure to potentially avoidable surgery.

BACKGROUND: PCA- and block-based enhanced recovery after surgery (ERAS) pathways have been shown to decrease hospital length of stay (HLOS) and opiate use following Nuss Repair for Pectus Excavatum (NRPE). No thoracic epidural-based ERAS pathway has demonstrated similar benefits. METHODS: In this pre-post single-center study, data were retrospectively collected for patients ≤ 21 years undergoing NRPE from May 2015 to August 2019. Univariate and multivariate methods were used to evaluate whether implementation of a thoracic epidural-based ERAS in April 2017 was associated with HLOS, opiate use, or pain scores. RESULTS: There were 110 patients: 35 pre- and 75 post-ERAS. HLOS decreased from median 4.8 (1.1) to 3.3 (0.6) days with ERAS (p < 0.001). Use of rescue intravenous opiates decreased from 35.3% pre- to 9.3% with ERAS (p = 0.013). When adjusted for baseline characteristics, ERAS was associated with a 1.3 ± 0.2 day decrease in HLOS and 0.188 times the odds of rescue intravenous opiate use (p = 0.011). CONCLUSIONS: Pain scores, ED visits, and readmissions did not change with ERAS (p > 0.05). Implementation of a thoracic epidural-based ERAS following NRPE was associated with decreased HLOS and need for any rescue intravenous opiates without a change in pain scores, ED visits, or readmission.

New regulations require living kidney donor (LKD) follow-up for 2 years, but donor retention remains poor. Electronic communication (eg, text messaging and e-mail) might improve donor retention. To explore the possible impact of electronic communication, we recruited LKDs to participate in an exploratory study of communication via telephone, e-mail, or text messaging postdonation; communication through this study was purely optional and did not replace standard follow-up. Of 69 LKDs recruited, 3% requested telephone call, 52% e-mail, and 45% text messaging. Telephone response rate was 0%; these LKDs were subsequently excluded from analysis. Overall response rates with e-mail or text messaging at 1 week, 1 month, 6 months, 1 year, and 2 years were 94%, 87%, 81%, 72%, and 72%. Lower response rates were seen in African Americans, even after adjusting for age, sex, and contact method (incidence rate ratio (IRR) nonresponse 2.07 5.8116.36 , P = .001). Text messaging had higher response rates than e-mail (IRR nonresponse 0.11 0.280.71 , P = .007). Rates of nonresponse were similar by sex (IRR 0.68, P = .4) and age (IRR 1.00, P > .9). In summary, LKDs strongly preferred electronic messaging over telephone and were highly responsive 2 years postdonation, even in this nonrequired, nonincentivized exploratory research study. These electronic communication tools can be automated and may improve regulatory compliance and postdonation care.

Importance: A standardized severity assessment approach is needed in children with appendicitis for postoperative adverse event estimation and severity adjustment for hospital-level comparative performance reporting. Objective: To examine the association between the presence and number of National Surgical Quality Improvement Program (NSQIP) Pediatric-defined intraoperative criteria for complicated appendicitis and outcomes in a population-based sample of children. Design, Setting, and Participants: This cohort study used data from the American College of Surgeons NSQIP Pediatric Appendectomy Procedure Targeted Participant Use Data File and General Participant Use Data File for children younger than 18 years who underwent appendectomy from January 1, 2019, through December 31, 2022, at 148 hospitals participating in NSQIP Pediatric. Exposure: The presence of NSQIP Pediatric intraoperative criteria for complicated appendicitis (ie, visible perforation, intraperitoneal abscess, extraluminal fecalith, and diffuse fibrinopurulent exudate). Main Outcomes and Measures: Adverse event outcomes included postoperative rates of any surgical site infection (incisional or organ space), percutaneous drainage, sepsis, and reoperation. Resource use outcomes included operative duration and hospital length of stay, and rates of postoperative imaging, parenteral nutrition use, and revisits. Multivariable regression was used to explore the influence of individual and combinations of intraoperative criteria on outcomes after adjusting for patient characteristics. Results: Of 82â¯950 patients included, 23â¯221 (27.9%) had at least 1 finding of complicated appendicitis. Compared with cases without any criteria present, the presence of each finding of complicated appendicitis was independently associated with higher rates of any adverse events; adjusted odds ratios (AORs) by finding were 5.57 (95% CI, 5.04-6.15) for visible hole, 4.83 (95% CI, 4.17-5.59) for diffuse fibrinopurulent exudate, 7.06 (95% CI, 5.77-8.63) for abscess, and 6.62 (95% CI, 4.78-9.15) for fecalith. An increasing number of criteria was associated with a stepwise increase in risk of any adverse events; AOR by number of criteria met were 5.55 (95% CI, 5.09-6.05) for 1 criterion, 8.86 (95% CI, 8.16-9.62) for 2 criteria, and 16.65 (95% CI, 15.10-18.35) for ≥3 criteria. Similar patterns in criteria-specific and cumulative implications for outcomes were observed with each individual adverse event and resource use measure. Conclusions and Relevance: This cohort study found that postoperative complications and increased resource use are associated with the presence and number of NSQIP Pediatric criteria for complicated appendicitis. These criteria should be considered the gold standard, evidence-based severity assessment framework for estimating risk of adverse events and resource use in children with appendicitis.
ABSTRACT
BACKGROUND/PURPOSE: Cephalosporins are considered safe and first-line prophylaxis in children with non-severe penicillin allergies. However, use of second-line agents is common and is primarily driven by poor allergic response documentation and misunderstanding of cross-reactivity risk. The goal of this project was to improve compliance with cephalosporin prophylaxis through improved documentation and targeted educational efforts. METHODS: A multidisciplinary working group including representatives from allergy, surgery, infectious disease, and pharmacy developed staged interventions to facilitate compliance with cephalosporin prophylaxis. These included: (1) caregiver outreach to clarify incomplete allergy documentation, (2) a decision-support algorithm for prophylaxis use in penicillin-allergic patients, (3) standardized educational resources for surgical faculty and rotating trainees, (4) email reminders with prophylaxis recommendations sent out prior to scheduled cases, and (5) EMR-based decision support during antibiotic ordering. Rates of complete allergy documentation and cephalosporin utilization were compared for general surgery procedures between a 12-month pre-intervention and 14-month post-intervention period. RESULTS: 578 patients with penicillin allergies recorded in the EMR were included (301 pre-intervention and 277 post-intervention), 54.0% of which received prophylaxis. Compared to the pre-intervention period, complete documentation of allergic reactions increased from 57.1% to 84.2% (p < 0.001) following implementation of all interventions. Appropriate prophylaxis utilization increased from 34.5% to 88.5% following implementation of all interventions (p < 0.001), and evidence of a stepwise increase in appropriate utilization was evident with each intervention stage. Persistent compliance failures during the post-implementation period were most commonly associated with urgent and emergent add-on cases. No adverse events or allergic responses were reported before or after project implementation. CONCLUSIONS: Compliance with cephalosporin prophylaxis significantly improved following a multidisciplinary effort targeting education, allergy documentation, and clinical support at the point of care. Ongoing efforts include postoperative audits within 24 h for noncompliant cases in order to identify barriers and improve compliance for urgent and emergent add-on cases. LEVEL OF EVIDENCE: III. TYPE OF STUDY: Prospective.

Importance: Gangrenous, suppurative, and exudative (GSE) findings have been associated with increased surgical site infection (SSI) risk and resource use in children with nonperforated appendicitis. Establishing the role for postoperative antibiotics may have important implications for infection prevention and antimicrobial stewardship. Objective: To compare SSI rates in children with nonperforated appendicitis with GSE findings who did and did not receive postoperative antibiotics. Design, Setting, and Participants: This was a retrospective cohort study using American College of Surgeons' National Surgical Quality Improvement Program (NSQIP)-Pediatric Appendectomy Targeted data from 16 hospitals participating in a regional research consortium. NSQIP data were augmented with operative report and antibiotic use data obtained through supplemental medical record review. Children with nonperforated appendicitis with GSE findings who underwent appendectomy between July 1, 2015, and June 30, 2020, were identified using previously validated intraoperative criteria. Data were analyzed from October 2022 to July 2023. Exposure: Continuation of antibiotics after appendectomy. Main Outcomes and Measures: Rate of 30-day postoperative SSI including both incisional and organ space infections. Complementary hospital and patient-level analyses were conducted to explore the association between postoperative antibiotic use and severity-adjusted outcomes. The hospital-level analysis explored the correlation between postoperative antibiotic use and observed to expected (O/E) SSI rate ratios after adjusting for differences in disease severity (presence of gangrene and postoperative length of stay) among hospital populations. In the patient-level analysis, propensity score matching was used to balance groups on disease severity, and outcomes were compared using mixed-effects logistic regression to adjust for hospital-level clustering. Results: A total of 958 children (mean [SD] age, 10.7 [3.7] years; 567 male [59.2%]) were included in the hospital-level analysis, of which 573 (59.8%) received postoperative antibiotics. No correlation was found between hospital-level SSI O/E ratios and postoperative antibiotic use when analyzed by either overall rate of use (hospital median, 53.6%; range, 31.6%-100%; Spearman ρ = -0.10; P = .71) or by postoperative antibiotic duration (hospital median, 1 day; range, 0-7 days; Spearman ρ = -0.07; P = .79). In the propensity-matched patient-level analysis including 404 patients, children who received postoperative antibiotics had similar rates of SSI compared with children who did not receive postoperative antibiotics (3 of 202 [1.5%] vs 4 of 202 [2.0%]; odds ratio, 0.75; 95% CI, 0.16-3.39; P = .70). Conclusions and Relevance: Use of postoperative antibiotics did not improve outcomes in children with nonperforated appendicitis with gangrenous, suppurative, or exudative findings.

Establishing a standardized and comprehensive framework for defining surgical quality is essential for meaningful performance measurement and process improvement efforts. The goal of this chapter is to provide a conceptual framework for defining surgical quality based on the perspectives of relevant stakeholders, and to identify infrastructure and care processes necessary for the delivery of high-quality surgical care. Central to this framework are the complementary approaches for quality assessment as outlined by the Institute of Medicine and Donabedian paradigms, and how these should be used together to develop a robust and granular taxonomy of quality constructs relevant to all surgical conditions. The utility of balancing and composite measures for quality assessment is also reviewed, as are practical considerations for identifying and prioritizing process improvement opportunities based on procedure volume and perioperative risk.

BACKGROUND: The goal of this study was to characterize contemporary performance benchmarks and risk factors associated with negative appendectomy (NA) in children with suspected appendicitis. METHODS: A multicenter retrospective cohort analysis of children undergoing appendectomy for suspected appendicitis was performed using data from the 2016-2021 NSQIP-Pediatric Appendectomy Targeted Public Use Files. Multivariable regression was used to evaluate the influence of year, age, sex, and WBC count on NA rate, and to generate rate estimates for NA based on different combinations of demographic characteristics and WBC profiles. RESULTS: 100,322 patients were included from 140 hospitals. The overall NA rate was 2.4%, and rates decreased significantly during the study period (2016: 3.1% vs. 2021: 2.3%, p < 0.001). In adjusted analyses, the highest risk for NA was associated with a normal WBC (<9000/mm3; OR 5.31 [95% CI: 4.87-5.80]), followed by female sex (OR 1.55 [95% CI: 1.42-1.68]) and age <5 years (OR 1.64 [95% CI 1.39, 1.94]). Model-estimated risk for NA varied significantly across demographic and WBC strata, with a 14.4-fold range in rates between subgroups with the lowest and highest predicted risk (males 13-17 years with elevated WBC [1.1%] vs. females 3-4 years with normal WBC [15.8%]). CONCLUSIONS: Contemporary NA rates have decreased over time, however NA risk remains high in children without a leukocytosis, particularly for girls and children <5 years of age. These data provide contemporary performance benchmarks for NA in children with suspected appendicitis and identify high-risk populations where further efforts to mitigate NA risk should be targeted.

BACKGROUND: The objective of this study was to evaluate the clinical utility of a routine predischarge WBC count (RPD-WBC) for predicting postdischarge organ space infection (OSI) in children with complicated appendicitis. STUDY DESIGN: This was a multicenter study using NSQIP-Pediatric data from 14 hospitals augmented with RPD-WBC data obtained through supplemental chart review. Children with fever or surgical site infection diagnosed during the index admission were excluded. The positive predictive value (PPV) for postdischarge OSI was calculated for RPD-WBC values of persistent leukocytosis (≥9.0 × 10 3 cells/µL), increasing leukocytosis (RPD-WBC > preoperative WBC), quartiles of absolute RPD-WBC, and quartiles of relative proportional change from preoperative WBC. Logistic regression was used to calculate predictive values adjusted for patient age, appendicitis severity, and use of postdischarge antibiotics. RESULTS: A total of 1,264 children were included, of which 348 (27.5%) had a RPD-WBC obtained (hospital range: 0.8 to 100%, p < 0.01). The median RPD-WBC was similar between children who did and did not develop a postdischarge OSI (9.0 vs 8.9; p = 0.57), and leukocytosis was absent in 50% of children who developed a postdischarge OSI. The PPV of RPD-WBC was poor for both persistent and increasing leukocytosis (3.9% and 9.8%, respectively) and for thresholds based on the quartiles of highest RPD-WBC values (>11.1, PPV: 6.4%) and greatest proportional change (<32% decrease from preoperative WBC; PPV: 7.8%). CONCLUSIONS: Routine predischarge WBC data have poor predictive value for identifying children at risk for postdischarge OSI after appendectomy for complicated appendicitis.

BACKGROUND: The objective was to explore the hospital-level relationship between routine pre-discharge WBC utilization (RPD-WBC) and outcomes in children with complicated appendicitis. METHODS: Multicenter analysis of NSQIP-Pediatric data from 14 consortium hospitals augmented with RPD-WBC data. WBC were considered routine if obtained within one day of discharge in children who did not develop an organ space infection (OSI) or fever during the index admission. Hospital-level observed-to-expected ratios (O/E) for 30-day outcomes (antibiotic days, imaging utilization, healthcare days, and OSI) were calculated after adjusting for appendicitis severity and patient characteristics. Spearman correlation was used to explore the relationship between hospital-level RPD-WBC utilization and O/E's for each outcome. RESULTS: 1528 children were included. Significant variation was found across hospitals in RPD-WBC use (range: 0.7-100%; p < 0.01) and all outcomes (mean antibiotic days: 9.9 [O/E range: 0.56-1.44, p < 0.01]; imaging: 21.9% [O/E range: 0.40-2.75, p < 0.01]; mean healthcare visit days: 5.7 [O/E 0.74-1.27, p < 0.01]); OSI: 14.1% [O/E range: 0.43-3.64, p < 0.01]). No correlation was found between RPD-WBC use and antibiotic days (r = +0.14, p = 0.64), imaging (r = -0.07, p = 0.82), healthcare days (r = +0.35, p = 0.23) or OSI (r = -0.13, p = 0.65). CONCLUSIONS: Increased RPD-WBC utilization in pediatric complicated appendicitis did not correlate with improved outcomes or resource utilization at the hospital level. LEVEL OF EVIDENCE: III.

Importance: The clinical significance of gangrenous, suppurative, or exudative (GSE) findings is poorly characterized in children with nonperforated appendicitis. Objective: To evaluate whether GSE findings in children with nonperforated appendicitis are associated with increased risk of surgical site infections and resource utilization. Design, Setting, and Participants: This multicenter cohort study used data from the Appendectomy Targeted Database of the American College of Surgeons Pediatric National Surgical Quality Improvement Program, which were augmented with operative report data obtained by supplemental medical record review. Data were obtained from 15 hospitals participating in the Eastern Pediatric Surgery Network (EPSN) research consortium. The study cohort comprised children (aged ≤18 years) with nonperforated appendicitis who underwent appendectomy from July 1, 2015, to June 30, 2020. Exposures: The presence of GSE findings was established through standardized, keyword-based audits of operative reports by EPSN surgeons. Interrater agreement for the presence or absence of GSE findings was evaluated in a random sample of 900 operative reports. Main Outcomes and Measures: The primary outcome was 30-day postoperative surgical site infections (incisional and organ space infections). Secondary outcomes included rates of hospital revisits, postoperative abdominal imaging, and postoperative length of stay. Multivariable mixed-effects regression was used to adjust measures of association for patient characteristics and clustering within hospitals. Results: Among 6133 children with nonperforated appendicitis, 867 (14.1%) had GSE findings identified from operative report review (hospital range, 4.2%-30.2%; P < .001). Reviewers agreed on presence or absence of GSE findings in 93.3% of cases (weighted κ, 0.89; 95% CI, 0.86-0.92). In multivariable analysis, GSE findings were associated with increased odds of any surgical site infection (4.3% vs 2.2%; odds ratio [OR], 1.91; 95% CI, 1.35-2.71; P < .001), organ space infection (2.8% vs 1.1%; OR, 2.18; 95% CI, 1.30-3.67; P = .003), postoperative imaging (5.8% vs 3.7%; OR, 1.70; 95% CI, 1.23-2.36; P = .002), and prolonged mean postoperative length of stay (1.6 vs 0.9 days; rate ratio, 1.43; 95% CI, 1.32-1.54; P < .001). Conclusions and Relevance: In children with nonperforated appendicitis, findings of gangrene, suppuration, or exudate are associated with increased surgical site infections and resource utilization. Further investigation is needed to establish the role and duration of postoperative antibiotics and inpatient management to optimize outcomes in this cohort of children.

BACKGROUND: Significant intercenter variation exists in mortality and death-censored graft loss (DCGL) after transplantation. Failure to rescue (FTR, death after a major complication) is an emerging tool in quality improvement and may underlie this variation. This study is the first effort to investigate the relationship between FTR and outcomes in transplantation to assess its utility in care improvement. METHODS: Using the Studies of Pediatric Liver Transplantation database, we identified 2330 children undergoing primary liver transplants at 21 centers. Centers were ranked by risk-adjusted mortality and sorted into tertiles. We then compared mortality, complications, and FTR across tertiles. RESULTS: Overall mortality was 4.9%, ranging from 1.4% to 8.1% in the low and high mortality tertiles (P < 0.01). The low mortality tertile had significantly lower rates of complications (30.9% vs 38.5% and 40.4%, P < 0.01) as well as FTR (4.6% vs 9.9% and 14.3%, P < 0.01). A similar trend was seen in the DCGL analysis. CONCLUSIONS: Our results demonstrate that although centers with higher mortality and DCGL have more frequent major complications, they exhibit 3-fold the rate of FTR. Efforts to standardize perioperative care, and thus minimize FTR, will have value to pediatric liver transplantation recipients. This preliminary study indicates that FTR may provide a useful quality improvement tool for the field of transplantation and warrants further investigation.

Photic cues influence daily patterns of activity via two complementary mechanisms: (1) entraining the internal circadian clock and (2) directly increasing or decreasing activity, a phenomenon referred to as "masking". The direction of this masking response is dependent on the temporal niche an organism occupies, as nocturnal animals often decrease activity when exposed to light, while the opposite response is more likely to be seen in diurnal animals. Little is known about the neural mechanisms underlying these differences. Here, we examined the masking effects of light on behavior and the activation of several brain regions by that light, in diurnal Arvicanthis niloticus (Nile grass rats) and nocturnal Mus musculus (mice). Each species displayed the expected behavioral response to a 1h pulse of light presented 2h after lights-off, with the diurnal grass rats and nocturnal mice increasing and decreasing their activity, respectively. In grass rats light induced an increase in cFOS in all retinorecipient areas examined, which included the suprachiasmatic nucleus (SCN), the ventral subparaventricular zone (vSPZ), intergeniculate leaflet (IGL), lateral habenula (LH), olivary pretectal nucleus (OPT) and the dorsal lateral geniculate (DLG). In mice, light led to an increase in cFOS in one of these regions (SCN), no change in others (vSPZ, IGL and LH) and a decrease in two (OPT and DLG). In addition, light increased cFOS expression in three arousal-related brain regions (the lateral hypothalamus, dorsal raphe, and locus coeruleus) and in one sleep-promoting region (the ventrolateral preoptic area) in grass rats. In mice, light had no effect on cFOS in these four regions. Taken together, these results highlight several brain regions whose responses to light suggest that they may play a role in masking, and that the possibility that they contribute to species-specific patterns of behavioral responses to light should be explored in future.
