A Scoping Review on Learning Health Networks Available in Pediatric Surgical Specialties.

BACKGROUND: Learning health networks (LHN) are consortia of institutions that collaborate and embrace the elements of the learning health system (LHS), including quality improvement, education, research, and stakeholder involvement. Their ultimate goal is rapid information dissemination in clinical care. Pediatric surgical specialties perform unique yet high-impact procedures that could benefit from LHN, thereby improving surgical outcomes and care through LHS approaches. Consequently, health system leaders should be aware of LHN and their importance in enhancing surgical care and improving outcomes. This scoping review aims to map and characterize the existing LHN applied in pediatric surgical specialties. METHODS: A systematic literature search was performed on Medline, EMBASE, and Scopus up to June 2022, with an update search conducted in May 2023. Additionally, Google Scholar, ProQuest and inquiry from topic experts were used for cross-referencing relevant review articles to identify grey literature. This scoping review was conducted and reported according to the PRISMA-scoping review extension. RESULTS: A total of 56 publications for 19 LHN were identified and included in this scoping review. Out of 19 identified LHN in pediatric surgical specialties, 18 were organized in North America. Eight of the networks are related to pediatric general surgery and another eight were related to pediatric transplantation. The 16 out of 19 LHN were initiated after 2001. To date, only eight of the LHNs generated reports of comparative improved outcomes. CONCLUSION: This scoping review provides an overview of the available LHNs in pediatric surgical specialties. Over the past decade, several pediatric surgical specialties have embraced the principles of learning health systems, forming inter-institutional collaborations that utilize information technology to generate big data on patient-level clinical information, engage in quality improvement cycles, adopt evidence-based practices, and actively involve patients and stakeholders.

Utilization of individual components of enhanced recovery after surgery (ERAS) protocol improves post-operative outcomes in adolescent idiopathic scoliosis: a blueprint for progressive adoption of ERAS.

PURPOSE: Enhanced recovery after surgery [ERAS] is an approach for standardization of perioperative care aimed at improving patient outcomes. The primary aim of this study was to determine if length of stay (LOS) differed by protocol type (ERAS vs. non-ERAS [N-ERAS]) in patients undergoing surgery for adolescent idiopathic scoliosis (AIS). METHODS: A retrospective cohort study was conducted. Patient characteristics were collected and compared between groups. Differences in LOS were assessed using regression adjusting for age, sex, BMI, pre-surgical Cobb angle, levels fused and year of surgery. RESULTS: Fifty nine ERAS patients were compared to 81 N-ERAS patients. Patients were comparable in their baseline characteristics. Median LOS was 3 days (IQR = 3-4) for the ERAS group, compared to 5 days (IQR = 4-5) for the N-ERAS group (p < 0.001). The ERAS group had a significantly lower adjusted rate of stay (RR = 0.75; 95% CI = 0.62-0.92). The ERAS group had significantly lower average pain on post-operative days 0 (least-squares-mean [LSM] 2.66 vs. 4.41, p < 0.001), POD1 (LSM 3.12 vs. 4.48, p < 0.001) and POD5 (LSM 2.84 vs. 4.42, p = 0.035). The ERAS group had lower opioid consumption (p < 0.001). LOS was predicted by the number of protocol elements received; those receiving two (RR = 1.54 95% CI = 1.05-2.24), one (RR = 1.49; 95% CI = 1.09-2.03) or none (RR = 1.60, 95% CI = 1.21-2.13) had significantly longer rates of stay than those receiving all four. CONCLUSION: Adoption of modified ERAS-based protocol for patients undergoing PSF for AIS led to significant reduction in LOS, average pain scores, and opioid consumption.

Scrotal flap phalloplasty as temporary neophallus in infants and children with penile agenesis: Multi-institutional experience and long-term follow-up.

INTRODUCTION: Aphallia is a rare congenital disorder pertaining to genotypic males. Early surgical creation of a neophallus is recommended to reinforce the child's male gender-identity, favoring proper psychosexual development. Modern microsurgical techniques used to create a neophallus in adults are not recommended in children due to the invasiveness and complexity of the procedures, along with high complication rates. Scrotal flap phalloplasty is a simple and reproducible technique to create a temporary neophallus in prepubertal boys with aphallia. OBJECTIVE: We present a multi-institutional experience, ten years after the initial description of the scrotal flap phalloplasty (SFP) technique, in which a flap from the well-developed scrotum is used to build a temporary neophallus, without obvious scars in patients with aphallia. STUDY DESIGN: The records of surgical neophalloplasty for aphallia patients from 4 centers between 2011 and 2021 were reviewed. All patients had at least one year follow-up to assess for short and long-term complications. Age at initial operation, associated anomalies, and other related surgical procedures were analyzed. RESULTS: The post-operative aesthetic result in all patients was satisfactory and has been maintained in the long-term follow-up, with all patients presenting a cylindrical structure resembling an uncircumcised penis, without evidence of significant contraction or loss of length. (Summary Figure) DISCUSSION: Non-microsurgical neophalloplasty techniques in patients with penile agenesis are temporary procedures that help to establish the body image and preserve the psychosexual development of the patient with aphallia. These techniques do not involve tissue transplant from a distant region, and are simpler to perform, with less scarring at the donor sites. Due to significant donor scars and considerable morbidity and complexity associated with the definitive phalloplasty techniques, we created a simple, reproducible and straightforward procedure to serve as a temporary neophallus in young boys with aphallia. As affected patients usually have a well-formed scrotum with normal and orthotopic testicles, it is the ideal donor site for a temporary neo-phallus in childhood. Furthermore, other donor sites are preserved for a definitive phalloplasty. There are limitations to this study, as quality of life could not be assessed and psychological or gender-identity investigations have not been carried out. None of these children have reached puberty, and hence decision and outcomes of definitive neophallus reconstruction has not been considered to date. CONCLUSION: Scrotal flap phalloplasty is a minimally invasive, simple and reproducible technique used to create a temporary neophallus in boys with aphallia, while waiting for definitive reconstructive surgery after puberty.

Ultrasonographical features of perinatal testicular torsion: an assessment of interobserver variability among radiologists and pediatric urologists.

PURPOSE: To retrospectively compare interpretations of Doppler ultrasound (US) in newborns with confirmed perinatal testicular torsion (PTT) by an experienced faculty (staff) pediatric radiologist (SPR), pediatric radiology fellow (PRF), pediatric urology fellow (PUF) and staff pediatric urologist (SPU). METHODS: US images of 27 consecutive males with PTT between May 2000 and July 2020 were retrieved. The testicles were classified as affected or non-affected by PTT. We performed a blinded comparison of interpretation by four assessors (SPR, PRF, PUF, SPU), with respect to the US features of PTT. Paired inter-rater agreement was calculated using Cohen's Kappa (κ) and overall agreement was assessed using Fleiss' kappa. RESULTS: Overall comparison using Fleiss' kappa found fair agreement for most features except testicular echogenicity and echogenic foci at interface for which there was poor agreement. Paired comparisons revealed better agreement between the SPR and PRF compared to the remaining two pairs, suggesting a need for the pediatric urologists (PUF and SPU) to acquaint themselves with testicular ultrasonography as this may have an impact on patient risk stratification and the quality of information given to parents. CONCLUSION: This study highlights the need for focused training program for pediatric urologists to attain similar agreement as the radiologists, suggesting a need for the pediatric urologists (PUF and SPU) to acquaint themselves with testicular ultrasonography as this may have an impact on patient risk stratification and the quality of information given to parents.

Optimizing the surgical instrument tray to immediately increase efficiency and lower costs in the operating room.

BACKGROUND: Surgical trays are often poorly configured and can be ongoing sources of frustration and excess costs. We conducted an observational study to determine if the use of a customized mathematical inventory optimization model would result in a greater reduction in the number of instruments on a surgical tray than a clinician review of the tray. METHODS: Utilization of instruments on the major orthopedic tray at a large academic hospital was documented over 80 procedures. Processes in the medical device reprocessing department and operating room were observed to comprehensively quantify all associated costs. Results of the observations were applied to a customized mathematical model to determine the ideal tray configuration. For comparison, a clinician review was also performed. RESULTS: The mathematical model alone produced an ideal tray size of 47 instruments, a reduction of 41 instruments from the original size of 88 instruments (47% reduction). This represented $34 440 in annual savings. In contrast, the clinician review alone suggested an ideal tray size of 67 instruments (23% reduction), representing $17 640 in annual savings. When clinicians were provided with the additional information from the model, they reduced the tray size to 51 instruments (42% reduction), producing $31 870 in savings. The mathematical model yielded an additional 22% instrument reduction and $14 230 in savings compared with clinician review alone. CONCLUSION: Our mathematical model is generalizable and can be applied to all specialties and hospitals to determine optimal tray configuration. As such, the financial implications are broad; at our institution, application to all surgical trays would result in $205 000 of savings annually. Surgeons and managers looking to streamline surgical trays should consider this evidence-based approach.

Impact of native nephrectomy on hypertension outcomes in pediatric kidney transplant recipients: a 10-year institutional experience.

OBJECTIVE: To assess the role native nephrectomy (NN) in hypertension-related outcomes for pediatric patients undergoing renal transplantation (RT). METHODS: Renal transplants (RT) performed at our institution between 2006 and 2015 were reviewed. RT recipients who underwent NN were compared to those who did not. Primary outcomes were hypertension-related: use/number of medications pre-/post-transplant and hypertension-related readmissions. Secondary outcomes were 1-year outcomes of: readmissions, eGFR, Clavien-Dindo classification ≥ 3 complications, and graft loss. RESULTS: 135 patients were evaluated. 24 underwent NN (Group 1) and 111 did not (Group 2). Baseline characteristics were similar between Groups 1 and 2. The majority of NN indications were hypertension (10/39 kidneys) and proteinuria (12/39 kidneys). There were no differences in use/number of anti-hypertensive medications pre- or post-transplant. However, between Group 2 and subgroup of patients who underwent NN for hypertension, a significant difference was seen in medication use/numbers but not post-transplant. Number of readmissions due to hypertension was similar (7.2% vs. 12.5%). The only difference in secondary outcomes was higher readmission rates with bacterial infections for group 1 (45.8% vs. 23.4%, p = 0.041). CONCLUSION: NN, when offered to patients at higher risk of post-RT hypertension, may allow high-risk patients to achieve similar hypertension outcomes as those at lower risk.

Serious and Fatal Complications after Neonatal Circumcision.

Neonatal circumcision (NNC) is the most frequently performed surgical procedure worldwide and is generally considered safe in Western societies. Deaths attributed to NNC are seldom reported and are mostly explained by lack of adherence to medical standards. We reviewed our emergency department database for circumcision-related emergency admissions. During 2000-2013, 19 previously healthy neonates were admitted for acute complications after circumcision. Four were admitted for bleeding, with hemophilia identified in two cases and von Willebrand disease in one. Eight boys required emergency surgery, three for severe bleeding. Four boys with amputation of the glans underwent immediate surgical reconstruction. One infant was taken to the operating room to remove an obstructing Plastibell ring. Seven boys were admitted to the intensive care unit with severe bleeding or sepsis, three of whom ultimately progressed to hemorrhagic or septic shock. Two of these children died of their complications. We estimate that the annual incidence of severe complications requiring hospitalization after NNC in the Greater Toronto Area was approximately 0.01%, and the incidence of fatalities over the 14-yr review period was approximately 0.0012%. Our results indicate that the risk of serious complications and death as a result of NNC is greater than generally assumed.

Omental Procedures During Peritoneal Dialysis Insertion: A Systematic Review and Meta-Analysis.

OBJECTIVES: Peritoneal dialysis (PD) is an option for ultrafiltration for patients with end-stage renal disease. Once placed, PD catheters may malfunction often due to omental wrapping. Omental procedures such as omentectomy and omentopexy may reduce this risk. This investigation aims to perform a systematic review and meta-analysis of the literature on the role of omental procedures on PD catheter insertions. METHODS: Following protocol registration on PROSPERO (CRD42020218950), a systematic review was performed in accordance with the Cochrane Collaboration. A literature search was performed in February 2021 across Medline, EMBASE, Scopus, and Cochrane Library. Records with patients who underwent PD catheter insertion with and without omental manipulation were included. The records underwent screening, full-text review, and data extraction. Study qualities were assessed using RoBINS-I and RoB2. Effect estimates were extracted as risk ratios and corresponding 95% confidence intervals (CI) were pooled using inverse variance method with random-effect model. RESULTS: Of 510 records identified, 15 studies were included in the meta-analysis (1 RCT, 2 prospective, 12 retrospective). With omental procedures, there was decreased the likelihood of failure requiring removal of PD catheter (RR 0.47, 95% CI 0.38, 0.58) and PD catheter obstruction (RR 0.23, 95% CI 0.14, 0.39); there was no difference in likelihood of catheter malposition or migration (RR 0.87, 95% CI 0.23, 3.29) or peritonitis (RR 0.74, 95% CI 0.40, 1.35). CONCLUSION: Based on the current low to moderate quality of evidence, omental manipulation at the time of PD catheter insertion confers benefits of decreased obstruction and failure requiring removal.

Perinatal testicular torsion: The clear cut, the controversial, and the "quiet" scenarios.

BACKGROUND: Perinatal testicular torsion (PTT) is a catastrophic event that occurs in utero or up to 30 days postnatally, with testicular loss being the most common outcome. OBJECTIVE: To assess clinical evaluation, surgical management and clinical outcomes in patients with PTT in a quaternary referral pediatric center, to determine testicular salvageability and propose future management options. METHODS: We retrospectively reviewed a cohort of males born outside the quaternary center with a diagnosis of PTT, from May 2000 to July 2020. Data collection included mode of delivery, gestational age, birth weight, testicular examination at birth, clinical presentation, ultrasound results at diagnosis, surgical management and findings, perioperative complications, and follow-up. RESULTS: 62 patients, including 2 patients with bilateral asynchronous PTT, were identified. Median (IQR) gestational age and birth weight were 39 (38-39.4) weeks and 3.4 (3.1-3.72) kg, respectively. Abnormal testicular examination at birth was found in 69% (Table 1). Doppler ultrasound was performed in all but 1 patient. 59 patients underwent surgery, 21 within 4 h, with bilateral exploration in 44 cases. Affected and non-affected testicles were explored in 76% and 98% of cases, respectively. 3 "nubbins" were found, of which 2 were excised. 3 nonsurgical complications were identified. During a median (IQR) follow-up of 3 (3-3) months, 63 testicles were removed or found to be non-functional, with compensatory hypertrophy in 38% of patients. CONCLUSION: Given that 3% of our patients presented with asynchronous bilateral PTT, as well as the safety of general anesthesia in a referral pediatric hospital, early bilateral scrotal exploration of PTT is recommended. LEVEL OF EVIDENCE: IV.

Comparison of interventions and outcomes of enhanced recovery after surgery: a systematic review and meta-analysis of 2456 adolescent idiopathic scoliosis cases.

PURPOSE: The objective of this meta-analysis and systematic review is to compare the methodology and evaluate the efficacy of Enhanced recovery after Spine Surgery (ERAS) for adolescent idiopathic scoliosis (AIS) and to compare the outcomes with traditional discharge (TD) pathways. METHODS: Using major databases, a systematic search was performed. Studies comparing the implementation of ERAS or ERAS-like and TD pathways in patients with AIS were identified. Data regarding methodology and outcomes were collected and analyzed. RESULTS: Fourteen studies (n = 2456) were included, comprising 1081 TD and 1375 ERAS or ERAS-like patients. Average age of patients was 14.6 ± 0.4 years. Surgical duration was on average 35.6 min shorter for the ERAS group compared to TD cohort ([2.8, 68.3], p = 0.03), and blood loss was 112.3 milliliters less ([102.4, 122.2], p < 0.00001). ERAS group reached first ambulation 29.6 h earlier ([11.2, 48.0], p-0.002), patient-controlled-analgesia (PCA) discontinuation 0.53 day earlier ([0.4, 0.6], p < 0.00001), urinary catheter discontinuation 0.5 day earlier ([0.4, 0.6], p < 0.00001), and length-of-stay (LOS) was 1.6 days shorter ([1.4, 1.8], p < 0.00001). Rates of complications and 30-day-readmission-to-hospital were similar between both groups. Pain scores were significantly lower for ERAS group on days 0 through 2 post-operatively. CONCLUSIONS: Use of ERAS after AIS is safe and effective, decreasing surgical duration and blood loss. ERAS methodology effectively focused on reducing time to first ambulation, PCA discontinuation, and urinary catheter removal. Outcomes showed significantly decreased LOS without a significant increase in complications. There should be efforts to incorporate ERAS in AIS surgery. Further studies are necessary to assess patient satisfaction. LEVEL OF EVIDENCE III: Meta-analysis of Level 3 studies.

A systematic review of outcomes of Deflux® treatment for vesicoureteral reflux following pediatric renal transplantation.

INTRODUCTION: Vesicoureteral reflux (VUR) after renal transplant in the pediatric population may be associated with an increased incidence of urinary tract infection (UTIs) leading to increased morbidity, including graft dysfunction and graft loss. The non-orthotopic location of the transplanted ureter, and lack of submucosal tunnel may pose challenges in correcting the VUR using endoscopic injection techniques. Herein we report the results of a systematic review evaluating the outcomes of endoscopic treatment of VUR using Deflux® in this population. METHODS: Pubmed and Embase databases were searched from October 2001 to April 2019. Full-text English articles involving patients less than 18 years old at the time of transplant, with a diagnosis of VUR post-transplantation, who underwent Deflux® treatment were included. Figure 1 outlines our PRISMA-compliant search strategy. RESULTS: We found 6 eligible studies describing Deflux® treatment outcomes in 67 pediatric patients with post-transplant VUR where voiding cystourethrogram (VCUG) confirmed the diagnosis and resolution of VUR. The mean success rate was 36.8%. Ureteral obstruction occurred in 7/67 cases (10.4%). In all these 7 cases of obstruction, ureteric stenting was the initial management, but was only successful in 1 patient. Open ureteroneocystostomy (UNC) was performed in 4/7 cases, while 2/7 were managed expectantly (unknown outcomes). Persistent VUR with UTI despite Deflux® were reported in 20 out of 67 cases. Of these, 7 were managed with prophylactic antibiotics, and 13 with UNC. Success rates were consistently low for UNC after failed Deflux® in comparison to redo UNC in transplant ureters without prior injection. CONCLUSION: Low success rates are seen following injection techniques for VUR after pediatric renal transplant. Although an appealing option, Deflux® may prove counterintuitive due to the high rate of obstruction and suboptimal results if open reimplantation is required. A multi-institutional prospective study with a larger population size may further elucidate these results.

Unnecessary ultrasounds in children with undescended testes: An interrogation of the impact of the Choosing Wisely campaigns and clinical practice guidelines.

OBJECTIVES: Over the past decade, clinical practice guidelines and educational campaigns have counselled against the use of routine ultrasound (US) in the diagnosis of undescended testes (UDT). We aimed to establish whether or not there has been change in the proportion of children with UDT undergoing pre-referral US prior to referral to our centre over this period. We also sought to determine whether type of referring specialist, UDT diagnosis, and patient distance from the hospital had impacted the rate of pre-referral US. METHODS: A select sample of hospital charts of children undergoing orchidopexy at a single tertiary paediatric urological referral centre between 2010 and 2019 were reviewed. Data regarding age at surgery, cryptorchidism diagnosis, type of referring physician, patient distance from institution, and evidence of US as part of diagnostic work-up were extracted. RESULTS: Five hundred charts were examined. Referring provider specialty impacted the number of US ordered (P=0.01). On subset analysis, paediatricians ordered fewer US for children with palpable UDT in 2014 (P=0.03). In 2018, community urologists ordered no US (P=0.02). These findings had temporal relationships with guideline release. The proportion of children undergoing US each year remained consistently between 50% and 62%, except in 2014, when only 36% had US. Distance from hospital and UDT diagnosis were of no significance. CONCLUSION: Despite clinical practice guidelines and Choosing Wisely campaign recommendations, significant numbers of children with UDT still undergo US. Transient changes in sub-specialty guideline adherence are observed. Strategies to improve sustained guideline awareness in referring clinicians need to be considered.

Comparative analysis of suturing technique in pediatric pyeloplasty on surgical outcomes.

PURPOSE: Pyeloplasty for ureteropelvic junction obstruction is the gold standard for surgical repair. There are currently no reports outlining optimal suturing technique. This paper compares the effect of suturing technique in dismembered pediatric pyeloplasty (open and laparoscopic) on post-operative outcomes. METHODS: A non-concurrent cohort study assessed different suturing techniques in both open and laparoscopic dismembered pyeloplasty performed two senior urologists at a tertiary referral pediatric center. Cases were stratified according to different suturing techniques for ureteropelvic anastomosis and subgroup analysis was performed according to open or laparoscopic approach. RESULTS: A total of 185 renal units were evaluated. The overall comparative analysis of different anastomotic suturing techniques and clustered analysis according to open and laparoscopic approach showed no significant differences on post-operative complication rate, leakage, stenosis, redo-pyeloplasties, operative time and hospital stay. There was a significant difference between suturing techniques on stent duration, age and weight of the patient. There was no effect of suture type or size on post-operative complication rate, leakage, UPJ stenosis and redo pyeloplasty rates, however, sample sizes were small. CONCLUSION: Suturing technique has no significant effect on the surgical outcomes assessed regardless of open or laparoscopic technique.

The role of bariatric surgery on kidney transplantation: A systematic review and meta-analysis.

INTRODUCTION: Obesity (body mass index [BMI] >35 kg/m2) remains a relative contraindication for kidney transplant, while patients after kidney transplantation (KTX) are predisposed to obesity. The present study aims to investigate the role of bariatric surgery in improving transplant candidacy in patients prior to KTX, as well its safety and efficacy in KTX patients postoperatively. METHODS: A systematic search was conducted up to March 2020. Both comparative and non-comparative studies investigating the role of bariatric surgery before or after KTX were considered. Outcomes included change in BMI, rates of mortality and complications, and the rate of patients who underwent KTX following bariatric surgery. Pooled estimates were calculated using the random effects meta-analysis of proportions. RESULTS: Twenty-one studies were eligible for final review; 11 studies investigated the role of bariatric surgery before KTX. The weighted mean BMI was 43.4 (5.7) kg/m2 at baseline and 33.9 (6.3) kg/m2 at 29.1 months followup. After bariatric surgery, 83% (95% confidence interval [CI] 57-99) were successfully listed for KTX and 83% (95% CI 65-97) of patients subsequently received successful KTX. Ten studies investigated the role of bariatric surgery after kidney transplant. Weighted mean baseline BMI was 43.8 (2.2) kg/m2 and mean BMI at 19.5 months followup was 34.2 (6.7) kg/m2. Overall, all-cause 30-day mortality was 0.5% for both those who underwent bariatric surgery before or after receiving a KTX. The results of this study are limited by the inclusion of only non-randomized studies, limited followup, and high heterogeneity. CONCLUSIONS: Bariatric surgery may be safe and effective in reducing weight to improve KTX candidacy in patients with severe obesity and can also be used safely following KTX.

Evolving trends in peri-operative management of pediatric ureteropelvic junction obstruction: working towards quicker recovery and day surgery pyeloplasty.

OBJECTIVE: To describe the evolution of practice patterns for pediatric pyeloplasty and determine how these changes have impacted length of stay (LOS), reoperation rates and return emergency department (ER) visits. METHODS: We reviewed our pyeloplasty database from 2008 to 2020 at a quaternary pediatric referral center and we included children 0-18 years undergoing pyeloplasty. Variables captured included: age, sex, baseline and follow-up anteroposterior diameter (APD) and differential renal function (DRF). We also collected data on the use of drains, catheters and/or stents, nausea and vomiting prophylaxis, opioids, regional anesthesia, and non-opioid analgesia. Outcomes were LOS, reoperation rates and ER visits. RESULTS: A total of 554 patients (565 kidneys) were included. Reoperation rate was 7%, redo rate 4% and ER visits 17%. There was a trend towards less opioids, indwelling catheters and internal stents and increasing non-opioid analgesia, externalized stents, and regional anesthesia during the study period. Same-day discharge (SDD) was possible for 88 (16%) children with no differences in reoperation or readmission rates between SDD and admitted (ADM). There was a difference in ER visits (21 [24%] vs. 26 [6%]; p = 0.04) for SDD vs. ADM, respectively. On multivariate analysis, the only predictor of ER visits was younger age. Patients < 7 months were more likely to present to ER (15/41; 37% vs. 6/47, 13%; p = 0.009). Multivariate analysis determined indwelling catheters and opioids were associated with ADM while dexamethasone and ketorolac with SDD. CONCLUSION: Progressive changes in care have contributed to a shorter LOS and increasing rates of SDD for pyeloplasty patients. SDD appears to be feasible and does not result in higher complication rates. These data support the development of a pediatric pyeloplasty ERAS protocol to maximize quicker recovery and foster SDD as a goal.

Utility of pre-transplant lower urinary tract investigation in pediatric renal transplant population after referral: A 16-year institutional experience.

To evaluate the clinical utility of pre-renal transplant LUT investigations in pediatric populations after their referral for transplant evaluation based on the etiology of their ESRD. A 16 year retrospective review of patients undergoing RT performed at our institution was performed. Patients were stratified into two groups: Group 1-non-urologic and Group 2-urologic etiology for ESRD. Baseline characteristics, pre-transplant LUT investigations, and urologic interventions were assessed. One-year clinical outcomes were compared between those with and without LUT investigations following referral for renal transplantation (RT). 227 patients and 97 patients were identified for Groups 1 and 2, respectively. 19% of Group 1 and 73% of Group 2 had VCUG, while 1% and 13%, respectively, had UDS ordered following referral for RT. In both groups, >50% of VCUG and UDS were ordered without specific clinical concerns. These had low likelihood of prompting interventions, both pre-transplant (Group 1-VCUG 0%, UDS 0%; Group 2-VCUG 0%, UDS 8%) or post-transplant (Group 1-0%, Group 2-5%). In both groups, LUT investigation following referral for RT did not lead to differences in 1 year outcomes assessed. In anticipation of pediatric RT, LUT investigations ordered without clinical indications did not provide information that altered management prior to transplantation.

Time Driven Activity Based Costing of Management Pathways for Vesicoureteral Reflux.

INTRODUCTION: The approach to the management of vesicoureteral reflux remains variable despite being a common pediatric diagnosis, which makes costing unpredictable. The aim of our study is to employ time driven activity based costing to characterize institutional costs of 3 management pathways for vesicoureteral reflux. METHODS: We developed process maps for vesicoureteral reflux management based on practice guidelines applicable to a hypothetical female patient with vesicoureteral reflux index with grade 3 unilateral reflux without bowel bladder dysfunction at our institution. The costs of 3 management pathways were described, including watch and wait, minimally invasive endoscopic surgery with dextranomer/hyaluronic acid and open re-implantation surgery. Costs for each pathway were calculated using the capacity cost rate ($/minute) for institutional resources and time estimates of resource use captured through direct observation and electronic medical record data. Clinical outcomes such as the breakthrough urinary tract infections or renal scarring were not addressed in this cost description. RESULTS: A substantial range of total costs ($CAD) was observed for all pathways including watch and wait ($1,683.58 to $2,041.12), minimally invasive endoscopic surgery ($2,616.35 to $4,012.89) and open re-implantation surgery ($3,317.76 to $3,924.82). Total costs for a single dimercaptosuccinic acid scan accounted for 8% to 15% of any pathway's overall costs. Material costs for voiding cystourethrogram imaging and endoscopic surgery were high at 59% and 64% to 76% of their individual total costs, respectively. For open re-implantation surgery, high costs were attributable to the longer use of operating room space and inpatient postoperative stay. CONCLUSIONS: Time driven activity based costing demonstrates significant cost variability in vesicoureteral reflux treatment modalities and identified local cost drivers to target. Results from this study may be used to inform future cost-effectiveness analyses.

Do post-operative phone calls enhance family satisfaction and outcomes after outpatient pediatric urological surgeries? A prospective study.

INTRODUCTION: This study assesses whether post-operative check-in phone calls (POPC) performed within 48 h of outpatient pediatric urological surgeries by a non-medical professional (NMP) would increase patient/family satisfaction and minimize extraneous resource use by increasing email/telephone communication, while reducing emergency department (ED) visits within 30 days of that procedure. METHODS: Families of patients undergoing ambulatory pediatric urology surgeries were enrolled over 8 weeks. Group 1 did not receive POPC. Group 2 received a POPC within 48 h of their operation by a NMP. Both groups received a phone-call survey 2 weeks after surgery to assess families' perioperative satisfaction. RESULTS: In total, 74 families were enrolled (Group 1 = 44, Group 2 = 31). The response rates to phone surveys for Groups 1 and 2 were 59.1% and 77.4%, respectively. POPC did not improve perioperative satisfaction, nor did it significantly promote the use of nursing email/telephone communication (19.2% vs. 4.2%, p = 0.128) or reduce ED visits (15.4% vs. 0.0%, p = 0.111). However, all families in Group 2 thought POPC was timed appropriately and 79.1% perceived it to be helpful in reducing post-operative anxiety. CONCLUSION: POPC by a NMP within 48 h of surgery may not affect perioperative satisfaction of families of patients undergoing same-day pediatric urology surgery but may have an impact in reducing post-operative anxiety.
