Abstract
To evaluate the efficiency and long-term renal function of nephron sparing surgery (NSS) in unilateral WT patients compared with radical nephrectomy (RN). The review was performed following Cochrane Handbook guidelines and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched five databases (Pubmed, Embase, Scopus, Web of Science and Cochrane) for studies reporting the efficiency and late renal function of NSS and/or RN on February 10, 2023. Comparative studies were evaluated by Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) and RoB 2.0. Assessed outcomes included survival rate, relapse rate, eGFR, renal dysfunction and hypertension. 26 studies involving 10322 unilateral WT cases underwent RN and 657 unilateral WT cases underwent NSS were enrolled. Overall effect estimates demonstrated that NSS significantly increased eGFR at follow-up (SMD, 0.38; 95% CI 0.05-0.72; p = 0.025) compared to that at diagnosis, and RN did not significantly decrease eGFR at follow-up (SMD, - 0.33; 95% CI - 0.77-0.11; p = 0.142) compared to that at diagnosis. Moreover, no significant difference was found in outcomes of survivability (OR, 1.38; 95% CI 0.82-2.32; p = 0.226), recurrence (OR, 0.62; 95% CI 0.34-1.12; p = 0.114), eGFR at follow-up (SMD, 0.16; 95% CI - 0.36-0.69; p = 0.538), renal dysfunction (OR, 0.36; 95% CI 0.07-1.73; p = 0.200) and hypertension (OR, 0.17; 95% CI 0.03-1.10; p = 0.063). Current evidence suggests that NSS is safe and effective for unilateral WT patients, because it causes better renal function and similar oncological outcomes compared with RN. Future efforts to conduct more high-quality studies and explore sources of heterogeneity is recommended.

Hospital Variation in Mortality and Failure to Rescue after Surgery for High-Risk Neonatal Diagnoses. Neonatology 2023; 121:34-45. [PMID: 37844560 DOI: 10.1159/000533825] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Accepted: 08/23/2023] [Indexed: 10/18/2023]
Abstract
INTRODUCTION A large proportion of postoperative mortality after pediatric surgery occurs among neonates with specific high-risk diagnoses. The extent to which there is hospital-level mortality variation among patients with these diagnoses and whether this variation is associated with differences in failure to rescue (FTR) is unclear. METHODS The Pediatric Health Information System® database (2012-2020) was used to identify patients who underwent surgery for eight high-risk neonatal diagnoses: gastroschisis; volvulus; necrotizing enterocolitis; intestinal atresia; meconium peritonitis; tracheoesophageal fistula; congenital diaphragmatic hernia; and perinatal intestinal perforation. Hospitals were stratified into tertiles of reliability-adjusted inpatient mortality rates (lower than average mortality - tertile 1 [T1]; higher than average mortality - tertile 3 [T3]). Multivariable hierarchical regression was used to evaluate the association between hospital-level, reliability-adjusted mortality and FTR. RESULTS Overall, 20,838 infants were identified across 48 academic, pediatric hospitals. Adjusted hospital mortality rates ranged from 4.0% (95% CI, 0.0-8.2) to 16.3% (12.2-20.4). Median case volume (range, 80-1,238) and number of NICU beds (range, 24-126) were not significantly different across hospital tertiles. Compared to the hospitals with the lowest postoperative mortality (T1), the odds of FTR were significantly higher in hospitals with the highest (T3) postoperative mortality (odds ratio 1.97 [1.50-2.59]). CONCLUSIONS Significant variation in neonatal hospital mortality for high-risk diagnoses does not appear to be explained by hospital structural characteristics. Rather, difference in FTR suggests quality improvement interventions targeting early recognition and management of postoperative complications could improve surgical quality and safety for high-risk neonatal care.

Abstract
OBJECTIVE The aim was to determine the association between risk adjusted hospital perioperative mortality rates, postoperative complications, and failure to rescue (FTR) after inpatient pediatric surgery. BACKGROUND FTR has been identified as a possible explanatory factor for hospital variation in perioperative mortality in adults. However, the extent to which this may be the case for hospitals that perform pediatric surgery is unclear. METHODS The Pediatric Health Information System database (2012-2020) was used to identify patients who underwent one of 57 high-risk operations associated with significant perioperative mortality (n=203,242). Academic, pediatric hospitals (n=48) were stratified into quintiles based on risk adjusted inpatient mortality [lower than average, quintile 1 (Q1); higher than average, quintile 5 (Q5)]. Multivariable hierarchical regression was used to evaluate the association between hospital mortality rates, complications, and FTR. RESULTS Inpatient mortality, complication, and FTR rates were 2.3%, 8.8%, and 8.8%, respectively. Among all patients who died after surgery, only 34.1% had a preceding complication (Q1, 36.1%; Q2, 31.5%; Q3, 34.7%; Q4, 35.7%; Q5, 32.2%; trend test, P =0.49). The rates of observed mortality significantly increased across hospital quintiles, but the difference was <1% (Q1, 1.9%; Q5; 2.6%; trend test, P <0.01). Relative to Q1 hospitals, the odds of complications were not significantly increased at Q5 hospitals [odds ratio (OR): 1.02 (0.87-1.20)]. By comparison, the odds of FTR was significantly increased at Q5 hospitals [OR: 1.60 (1.30-1.96)] with a dose-response relationship across hospital quintiles [Q2-OR: 0.99 (0.80-1.22); Q3-OR: 1.26 (1.03-1.55); Q4-OR: 1.33 (1.09-1.63)]. CONCLUSIONS The minority of pediatric surgical deaths are preceded by a postoperative complication, but variation in risk adjusted mortality across academic, pediatric hospitals may be partially explained by differences in the recognition and management of postoperative complications. Additional work is needed to identify children at greatest risk of postoperative death from perioperative complications as opposed to those at risk from pre-existing chronic conditions.

Abstract
INTRODUCTION Abdominal compartment syndrome (ACS) is the presence of intra-abdominal hypertension with systemic, multiorgan effects and is associated with high mortality, yet the national incidence and mortality rates of pediatric ACS remain unknown. The aim of this study is to evaluate the incidence and mortality of pediatric ACS over a 13-year period across multiple children's hospitals and between individual children's hospitals in the United States. METHODS We performed a retrospective cohort study on children (aged < 18 y) with ACS in the Pediatric Health Information Systems database from 2007 to 2019. We identified ACS patients by International Classification of Diseases codes in the ninth and 10th revision. The primary outcomes were incidence and mortality, which were analyzed by year, age, and hospital of admission. RESULTS Across 49 children's hospitals, we identified 2887 children with ACS from 2007 to 2019 in the Pediatric Health Information Systems database. The overall incidence of ACS was 0.17% and the overall mortality was 48.87%. There was no significant difference in annual incidence (P = 0.12) or mortality (P = 0.39) over the study period. There was no difference in incidence across age group (P = 0.38); however, mortality in patients 0-30 d old (58.61%) was significantly higher than older age groups (P < 0.0001). The hospital-specific incidence (0.04%-0.46%) and mortality (28.57%-71.43%) varied widely. CONCLUSIONS The annual incidence and mortality of pediatric ACS are unchanged from 2007 to 2019. ACS mortality remains high, especially in neonatal intensive care unit patients. No obvious correlation is seen between incidence rates and mortality. Differing hospital-specific incidence and mortality could suggest inconsistencies between institutions that affect pediatric ACS care, perhaps with respect to recognition and diagnosis.

Retrograde stent with external string for pediatric robotic pyeloplasty: does it reduce cost and complications? J Robot Surg 2023; 17:185-189. [PMID: 35488080 DOI: 10.1007/s11701-022-01411-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2022] [Accepted: 03/27/2022] [Indexed: 10/18/2022]
Abstract
Robotic-assisted pyeloplasty (RAP) is a mainstay in the treatment of ureteropelvic junction obstruction (UPJO) in children. At our institution, to limit planned operating rooms visits we have placed a ureteral stent with an external string (SWES) immediately prior to RAP. In this study, we sought to quantify the operative time, complications, and costs associated with this approach compared to the traditional approach, requiring subsequent stent removal in the operating room. We hypothesized the SWES cohort would have decreased cost, yet with similar operative time and complications. We retrospectively collected all RAPs performed at our institution using the SWES approach (Aug 2012-July 2017). We excluded those with a redo pyeloplasty, and/or a percutaneous nephrostomy tube for post-operative drainage. We collected 30-day costs linked to the patients' MRN using the Pediatric Health Information System (PHIS) database. We compared 30-day healthare costs for all patients following RAP. We compared our SWES group to a national cohort of all pediatric RAP during the same time period. Lastly, we sent an anonymous, electronic survey to urologists of all PHIS institutions to identify the predominant postoperative drainage, nationally. Within our institution, we reviewed all those treated with SWES (n = 85) (Table 1). The median 30-day cost was $10,548 among those with SWES (Table 2). This was significantly less than the overall, national cohort of all pediatric RAP during the same period ($14,119, p < 0.001). There was a 15.5 % rate of unplanned return to the hospital in the SWES group. Of those unplanned returns, 8.2 % (7/85) had unplanned return for a procedure (3 for unplanned stent removal, 2 for nephrostomy tube for persistent obstruction, 1 for omental hernia, and 1 for stent replacement). With a 42.5 % (37/87) response rate, our nationwide survey found 84.6 % primarily leave stents WITHOUT a string, 7.7 % left nephrostomy tubes, and 7.7 % stents with strings. During pediatric RAP, placement of a SWES takes little time, carries a risk of unplanned visit to the operating room, saves the patient a certain, second anesthetic for stent removal, and amounts to a cost savings of approximately 25 %.

Abstract
INTRODUCTION Studies have shown the benefit of intensive care unit (ICU) bundled protocols; however, they are primarily derived from medical patients. We hypothesized that patients and their medication profiles are different between critically ill medical, surgical, and trauma patients. METHODS The Pediatric Health Information System 2017 dataset was used to perform a retrospective cohort study of critically ill children. The pediatric medical, surgical, and trauma cohorts were separated based on ICD-10 codes. Data collected included demographics, secondary diagnoses, outcomes, and medication data. Medications were grouped as opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, paralytics, and "other" sedatives. A non-parametric Kolmogorov-Smirnov test (KS test) and odds ratios (reference group: medical cohort) were calculated to compare medication administration between the study cohorts for the first 30 ICU days. RESULTS A total of 4488 critically ill children (medical 2078, surgical 1650, and trauma 760) were identified. The trauma cohort had increased incidence of delirium (medical 10.8%, surgical 11.5%, trauma 13.8%; p < 0.01) and mortality (medical 5.4%, surgical 2.4%, trauma 11.7%; p < 0.01). For all study cohorts, > 50% received GABA-agonists on ICU days 0-30. With the KS test, there was a significant difference in administration of opiates, GABA-agonists, alpha-2 agonists, anti-psychotics, and "other" sedatives over the first 30 days in the ICU. Relative to medical patients, trauma patients had significantly higher odds of receiving anti-psychotics on ICU days 10-20 and 22-24. CONCLUSION Critically ill pediatric trauma, medical, and surgical patients are distinctly different patient populations with differing pharmacologic profiles for analgesia, sedation, and delirium. LEVEL OF EVIDENCE Level III (Retrospective Comparative Study).

Abstract
Renal cell carcinoma (RCC) is rare in children but is the most common renal tumor in adults. Pediatric RCC has different clinical characteristics, histopathology, and treatment compared with adult disease. Databases were reviewed from inception to February 2020, identifying 32 publications pertaining to 350 patients under 27 years. Surgery is the cornerstone for cure in localized RCC. Lymph node dissection remains controversial. Conventional radiotherapy has no curative role in RCC; similarly, conventional chemotherapy has not proven to be effective in large cohorts. Pediatric metastatic RCC has a poor outlook. There are no published prospective studies demonstrating which adjuvant therapy could improve outcome. Sunitinib, a tyrosine kinase inhibitor, is recommended in this group despite limited evidence. This review provides an overview for pediatric RCC, including the evolving role of precision medicine.

Abstract
Standard of care for unilateral nephroblastoma includes total nephrectomy (TN) with nodal sampling. We sought to compare the outcomes of TN and partial nephrectomy (PN). We performed a retrospective cohort study of TN and PN for nephroblastoma using the National Cancer Data Base. The outcomes included nodal sampling frequency, margin status, and survival. Categorical and continuous data were evaluated with χ2 and t tests, respectively ( P < 0.05). Generalized linear models evaluated nodal sampling and margin status. Cox regression compared survival. In total, 235 patients underwent PN and 3572 had TN. TN patients were 50 per cent more likely to undergo nodal sampling (RR: 1.47, 95% CI 1.30–1.66). There was no difference in margin status (RR: 0.91, 95% CI 0.65–1.28) or overall survival (HR 1.57; 95% CI 0.78–3.19). This study reports the largest review of patients with PN for unilateral nephroblastoma. PN patients had less nodal sampling but similar margin involvement and overall survival.

Abstract
OBJECTIVES The incidence of pediatric acute pancreatitis (AP) increased over the past 2 decades and is estimated to be 3 to 13 per 100,000. The impact of rising AP incidence on health care costs is unknown. Our aim was to examine pediatric AP admissions and associated hospital costs in the United States between years 2004 and 2014. METHODS Acute pancreatitis admission and cost data were extracted from the Pediatric Health Information System. We determined AP admission and cost percentages each year, as well as the ratio of AP cost to admission percentages to estimate AP "burden." Length of stay, costs of hospitalization, and the effect of intensive care unit care on these estimates were examined. RESULTS Between 2004 and 2014, AP admission percentages increased (P = 0.002). Length of stay decreased over time (P < 0.0001) and was longer for those requiring intensive care unit care (P < 0.0001). Acute pancreatitis admissions cost per day significantly increased over time (P < 0.0001). Median AP cost percentage remained 1.2 to 1.7 times higher than AP admission percentage. CONCLUSIONS Acute pancreatitis admissions constitute an expensive burden on the health care system relative to the percentage of all admissions. If AP admissions continue to increase, the cost of AP admissions may pose a substantial financial health care burden.

Abstract
PURPOSE To investigate the safety and efficacy of nephron-sparing surgery (NSS) in the treatment of pediatric Xp11.2 translocation renal cell carcinoma (RCC). METHODS Clinical characteristics of 9 RCC children (7 males and 2 females) with Xp11.2 translocation who received NSS between January 1973 and December 2015 were retrospectively analyzed. The mean age was 7.8years (range: 4.5-13.5years). Xp11.2 translocation RCC was found in the left side in 4 patients and right in 5. 3 tumors were located in the upper pole of the kidney, 1 in the middle dorsal, 1 in the middle ventral and 4 in the lower pole. RCC presented with painless gross hematuria in 4 patients, abdominal mass in 1, and as an incidental finding by ultrasound examination in 4 patients. The mean course of hematuria was 3months (range: 1-7months). The mean tumor diameters were 3.7cm (range: 2.2-6.9cm). RESULTS All the patients received NSS with open transperitoneal approach. The mean operative time and estimated blood loss were 115min and 40ml, respectively. The time of renal pedicle clamping was 19-25min (mean: 21.5min). No complications (such as leakage of urine, prolonged drainage or secondary bleeding) were noted. No patients experienced local recurrence during the mean of 50.1-month follow-up (range: 13-117months). Intravenous urography (IVU) or contrast-enhanced CT was conducted at 6months after surgery which showed favorable kidney function in all patients. CONCLUSION Xp11.2 translocation RCC is a predominant pathological but biologically inert type of pediatric RCC. For Xp11.2 translocation RCC sized <4-7cm in diameter and located in one pole, NSS is safe and feasible. TYPE OF STUDY Treatment Studies, LEVEL IV.

Abstract
Analysis of data from large administrative databases and patient registries is increasingly being used to study childhood cancer care, although the value of these data sources remains unclear to many clinicians. Interpretation of large databases requires a thorough understanding of how the dataset was designed, how data were collected, and how to assess data quality. This review will detail the role of administrative databases and registry databases for the study of childhood cancer, tools to maximize information from these datasets, and recommendations to improve the use of these databases for the study of pediatric oncology.

Abstract
INTRODUCTION Radical nephrectomy (RN, or total nephrectomy) is the current gold-standard surgical treatment for children with Wilms tumors (WT). However, nephron-sparing surgery (NSS, or partial nephrectomy) has recently been gaining increasing attention. The objective of this systematic review is to compare the effectiveness of NSS as compared with RN for the treatment of children with WT. METHODS We searched the Cochrane Controlled Trials Register, clinicaltrials.gov, MEDLINE, EMBASE, Google Scholar, and recently presented meeting abstracts for reports in English. The bibliographies of included studies were then hand-searched for any missed articles. The protocol was prospectively registered. Manuscripts were assessed and data abstracted in duplicate with differences resolved by the senior author. Owing to high heterogeneity among the final included studies, only a qualitative systematic review was performed; no formal meta-analysis was undertaken. RESULTS We identified 694 articles, 118 of which were selected for full-text review and 66 of which were included in the final analysis. Most studies were single- or multi-institution retrospective case series (60, 91%), with a small number of prospective cohort studies (6, 9%) and 1 administrative database analysis. Most studies were from Europe (27, 41%) or North America (21, 32%). Nearly half (32, 48%) of studies those were included were dated from 2010 or later. In total, data on 4,002 patients were included, of whom 1,040 (26%) underwent NSS and 2,962 (74%) underwent NSS. Reported rupture rates were similar between RN and NSS (13% vs. 7%), as were recurrence rates (12% vs. 11%) and survival rates (85% vs. 88%). However, these comparisons are limited by inherent biases in the design and reporting of most included studies. CONCLUSIONS Most contemporary studies reporting the use of NSS in children with WT report similar long-term outcomes to RN. However, most existing studies are limited by their small numbers, inconsistent reporting, and methodological biases. There are significant opportunities for future research on the use of NSS in children with WT, including issues related to surgical quality, optimal technique, timing and duration of chemotherapy, and variation in the use of NSS among centers.

Practice patterns and outcomes of pediatric partial nephrectomy in the United States: Comparison between pediatric urology and general pediatric surgery. J Pediatr Urol 2015; 11:171.e1-5. [PMID: 26052003 DOI: 10.1016/j.jpurol.2015.04.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2015] [Accepted: 04/20/2015] [Indexed: 11/15/2022]
Abstract
BACKGROUND In the United States, both pediatric urologists (PUROs) and general pediatric surgeons (GPSs) perform nephrectomies in children, with PUROs performing more nephrectomies overall, most commonly for benign causes. GPSs perform more nephrectomies for malignant causes. We questioned whether the same trends persisted for partial nephrectomy. OBJECTIVE We hypothesized that PUROs performed more partial nephrectomies for all causes, including malignancy. Our primary aim was to characterize the number of partial nephrectomies performed by PUROs and GPSs. We also compared short-term outcomes between subspecialties. STUDY DESIGN We analyzed the Pediatric Health Information System (PHIS), a database encompassing data from 44 children's hospitals. Patients were ≤18 years old and had a partial nephrectomy (ICD-9 procedure code 554) carried out by PUROs or GPSs between 1 January, 2004 and June 30, 2013. Queried data points included surgeon subspecialty, age, gender, 3M™ All Patient Refined Diagnosis Related Groups (3M™ APR DRG) code, severity level, mortality risk, length of stay (LOS), and medical/surgical complication flags. Data points were compared in patients on whom PUROs and GPSs had operated. Statistical analysis included the Student t test, chi-square test, analysis of covariance, and logistic regression. RESULTS Results are presented in the table. While PUROs performed the majority of partial nephrectomies, GPSs operated more commonly for malignancy. For surgeries performed for non-malignant indications, PURO patients had a shorter LOS and lower complication rate after controlling for statistically identified covariates. There was no difference in LOS or complication rate for patients with malignancy. DISCUSSION A Pediatric Health Information System study of pediatric nephrectomy demonstrated PUROs performed more nephrectomies overall, but GPSs performed more surgeries for malignancy. The difference was less dramatic for partial nephrectomies (63% GPS, 37% PURO) than for radical nephrectomies (90% GPS, 10% PURO). PUROs performed more partial nephrectomies for benign indications (94% PURO, 6% GPS) at an even greater rate than nephrectomies (88% PURO, 12% GPS). As a national database study, there are a number of inherent limitations: applicability of results to non-participating hospitals, possibility of inaccurate data entry/coding, and lack of data points that would be relevant to the study. CONCLUSIONS While most partial nephrectomies in the United States are performed by PUROs, GPSs perform the majority of surgeries for malignancy. There is no difference in LOS or complication rate undergoing nephron-sparing surgery for malignant disease; however, PUROs had a shorter LOS and lower complication rate when operating for benign diseases.

Abstract
OBJECTIVE Given the negative long-term effects of renal insufficiency, nephron-sparing surgery (NSS) is increasingly discussed for the treatment of pediatric renal tumors. We sought to examine variation in practice patterns of NSS among children with renal tumors. MATERIALS AND METHODS We performed a retrospective cohort analysis of claims data for pediatric inpatient admissions captured by the Kids Inpatient Database (1997-2009). We identified children with renal tumors who underwent surgery, including radical nephrectomy (RN) and NSS. We used multivariable logistic regression to assess the relationship between use of NSS and various clinical, demographic, and geographic predictors of interest. RESULTS We identified 10,108 pediatric inpatient admissions for renal tumors. Of these, 1657 were surgical admissions, with 1501 patients (90.5%) undergoing RN and 156 (9.5%) undergoing NSS. On multivariable analysis, NSS was associated only with a concomitant diagnosis of renal insufficiency (relative ratio [RR] 3.37, p = 0.01) and surgery in the Northeastern USA (RR 3.07, p = 0.03). Race/ethnicity, age, payer type, procedure year, and other non-clinical factors were not significantly associated with NSS. CONCLUSION In a large, nationwide pediatric cohort, RN remains the most common surgical intervention for renal tumors. NSS is significantly associated with a diagnosis of renal insufficiency, but not non-clinical factors such as patient gender or race. © 2014 Published by Elsevier Ltd on behalf of Journal of Pediatric Urology Company.

Trends in the Rates of Pediatric Pyeloplasty for Ureteropelvic Junction Obstruction over 19 Years: A PHIS Database Study. Adv Urol 2014; 2014:142625.

Abstract
Background. Over the past 20 years, the management of ureteropelvic junction obstruction (UPJ) has shifted. While many urologists note a decrease in the number of pyeloplasties performed over time, the nature of the change in practice has yet to be defined. In the current study, we utilize a national, multi-institutional database of children's hospitals to evaluate trends in patients undergoing pyeloplasty as well as the rate of surgical reconstruction over the past 20 years. Material/Methods. We queried the Pediatric Health Information System (PHIS) database for all children undergoing primary pyeloplasty between 1992 and 2011. Clinical variables, including age at time of surgery, gender, length of stay (LOS), and geographic region, were determined. Age-adjusted rate of repair was also calculated per 100,000 PHIS inpatients. Results. 6,013 patients were included in the study, of which 71.6% were male and 64.2% were under the age of 24 months at time of surgery. Over the study period, the median age at time of surgery increased from 2-4 months to 12-14 months (P < 0.01). LOS decreased from a median of 5 days to 2 days (P < 0.001). The rate of surgery increased by 10.6 pyeloplasties per 100,000 PHIS inpatients from 1992 to 2011 (P < 0.01). The highest rate of pyeloplasty was in the northeast. The increase in pyeloplasties performed from 1992 to 1999 was specific to children aged greater than 24 months, while rates stayed the same in infants younger than 2 years during the same time period. In contrast, from 1999 to 2011, the rate of pyeloplasty decreased in patients less than 2 years of age, while the rate remained constant in patients over age 2. Conclusion. The rate of pyeloplasty increased in PHIS hospitals from 1992 to 2011. Trends are due to an increase in surgery in infants younger than 2 years from 1992 to 1999, followed by a progressive surgical rate decline, characterized by a shift towards patients older than 2 years of age.

Abstract
BACKGROUND/PURPOSE Administrative databases include large multi-institutional cohorts of patients with rare congenital anomalies that can potentially be used to characterize these diseases and study variations in practice and outcomes. The purpose of this study was to develop a methodology to accurately identify a cohort of patients with a rare disease (esophageal atresia and tracheoesophageal fistula, EA/TEF) in the Pediatric Health Information System (PHIS) database. METHODS Patients with EA/TEF treated from 2001 to 2010 were identified by chart review at two institutions and then located within the PHIS database to find ICD-9-CM coding patterns unique to EA/TEF. Subsequently, a step-wise search strategy for PHIS was developed to identify patients with EA/TEF: this included searching the ICD-9-CM diagnosis code for congenital EA/TEF; adding the ICD-9-CM code for acquired TEF; limiting age to ≤ 30 days; and adding at least one of a number of specified ICD-9-CM procedure codes. The PHIS search results were subsequently validated by chart review at each institution. RESULTS The institutional chart reviews identified 207 patients with EA/TEF. The most refined PHIS search strategy identified 221 patients. The positive predictive value of the search increased incrementally from 65% with using only the correct ICD-9 code to 96% with the full methodology. A cohort of 2977 patients with EA/TEF is identified when this search strategy is applied to the entire PHIS database. CONCLUSION Administrative databases such as PHIS can be utilized to identify cohorts of patients with rare congenital anomalies; however, cohort development requires a systematic search strategy and validation process to ensure correct identification of patients.

Abstract
OBJECTIVE To describe inter-center hospital variation in inhaled nitric oxide (iNO) administration to infants born prior to 34 weeks' gestation at US children's hospitals. METHODS This was a retrospective cohort study using the Pediatric Health Information System to determine the frequency, age at first administration, and length of iNO use among 22 699 consecutive first admissions of unique <34 weeks' gestation infants admitted to 37 children's hospitals from January 1, 2007, through December 31, 2010. RESULTS A total of 1644 (7.2%) infants received iNO during their hospitalization, with substantial variation in iNO use between hospitals (range across hospitals: 0.5%-26.2%; P < .001). The age at which iNO was started varied by hospital (mean: 20.0 days; range: 6.0-65.1 days, P < .001), as did the duration of therapy (mean: 13.1 days; range: 1.0-31.1 days; P < .001). Preterm infants who received iNO were less likely to survive (36.3% mortality vs 8.3%; odds ratio: 6.27; P < .001). The association between the use of iNO and mortality persists in propensity score-adjusted analyses controlling for demographic factors and diagnoses associated with the use of iNO (odds ratio: 3.79; P < .0001). CONCLUSIONS iNO practice patterns in preterm infants varied widely among institutions. Infants who received iNO were less likely to survive, suggesting that iNO is used in infants already at high risk of death. Adherence to National Institutes of Health consensus guidelines may decrease variation in iNO use.
