Development of a Standardized Algorithm for Management of Newly Diagnosed Anorectal Malformations.

Neonates with a new diagnosis of anorectal malformation (ARM) present a unique challenge to the clinical team. ARM is strongly associated with additional midline malformations, such as those observed in the VACTERL sequence, including vertebral, cardiac, and renal malformations. Timely assessment is necessary to identify anomalies requiring intervention and to prevent undue stress and delayed treatment. We utilized a multidisciplinary team to develop an algorithm guiding the midline workup of patients newly diagnosed with ARM. Patients were included if born in or transferred to our neonatal intensive care unit (NICU), or if seen in clinic within one month of life. Complete imaging was defined as an echocardiogram, renal ultrasound, and spinal magnetic resonance imaging or ultrasound within the first month of life. We compared three periods: prior to implementation (2010-2014), adoption period (2015), and delayed implementation (2022); p ≤ 0.05 was considered significant. Rates of complete imaging significantly improved from pre-implementation to delayed implementation (65.2% vs. 50.0% vs. 97.0%, p = 0.0003); the most growth was observed in spinal imaging (71.0% vs. 90.0% vs. 100.0%, p = 0.001). While there were no differences in the rates of identified anomalies, there were fewer missed diagnoses with the algorithm (10.0% vs. 47.6%, p = 0.05). We demonstrate that the implementation of a standardized algorithm can significantly increase appropriate screening for anomalies associated with a new diagnosis of ARM and can decrease delayed diagnosis. Further qualitative studies will help to refine and optimize the algorithm moving forward.

Impact of Insurance Expansion on Disposition for Pediatric Trauma Patients: A National Trauma Data Bank Cohort Study.

BACKGROUND: The insurance status of pediatric trauma patients is associated with access to post-discharge resources, including inpatient rehabilitation. Our goal was to understand the impact of changes in insurance coverage on access to post-acute care resources for pediatric trauma patients. MATERIALS AND METHODS: We utilized the National Trauma Data Bank from 2012 to 2016 for all pediatric trauma patients with a highest body region abbreviated injury score >2. Our primary outcome was hospital discharge disposition location. We used multivariable regression to adjust for salient patient and trauma center characteristics. Additionally, we performed a sensitivity analysis including only high-volume hospitals to examine the relationship between the magnitude of facility level expansion in coverage and changes in patient disposition. RESULTS: We identified 195,649 pediatric trauma patients meeting inclusion criteria. From 2012 to 2016 the proportion of patients with Medicaid (35% versus 39%, P < 0.001) and private insurance (39% versus 45%, P < 0.001) increased. Increased discharges with home health (HH) (+0.6% adjusted risk difference 2012 to 2016, P < 0.001) and decreased discharges to inpatient rehabilitation and skilled nursing facilities (-0.6% adjusted risk difference 2012 to 2016, P = 0.01) were associated with changes in insurance coverage. After stratifying high volume facilities by magnitude of increase in Medicaid and private insurance, we found that, for all groups, discharge to inpatient rehabilitation and skilled nursing facilities decreased (P < 0.01). CONCLUSIONS: Expanded insurance coverage for children was paradoxically associated with decreased discharge to inpatient rehabilitation and skilled nursing facilities after severe traumatic injury. These findings suggest that additional barriers may drive limitations in access to pediatric post-discharge services.

Impact of Botulinum Toxin on Hirschsprung-Associated Enterocolitis After Primary Pull-Through.

BACKGROUND: Hirschsprung-associated enterocolitis (HAEC) is a serious potential complication after primary pull-through surgery for Hirschsprung's disease (HSCR). Administration of anal botulinum toxin (BT) injection may improve obstructive symptoms at the internal anal sphincter, leading to improved fecal passage. The timing of administration and effects on delay or prevention of HAEC are unknown. We hypothesized that BT administration increased the postoperative time to HAEC and aimed to investigate whether anal BT administration after primary pull-through surgery for HSCR is associated with increased time to inpatient HAEC admission development. METHODS: We performed a retrospective cohort study examining children with HSCR at US children's hospitals from 2008 to 2018 using the Pediatric Health Information System database with an associated primary pull-through operation performed before 60 d of age. The intervention assessed was the administration of BT concerning the timing of primary pull-through, and two groups were identified: PRO (received BT at or after primary pull-through, before HAEC) and NOT (never received BT, or received BT after HAEC). The primary outcome was time from pull-through to the first HAEC admission. The Cox proportional hazards model was developed to examine the BT administration effect on the primary outcome after controlling for patient-level covariates. RESULTS: We examined a total of 1439 children (67 in the PRO and 1372 in the NOT groups). A total of 308 (21.4%) developed at least one episode of HAEC, including 76 (5.3%) who had two or more episodes. Between 2008 and 2018, the frequency of BT administration has increased from three to 20 hospitals with a frequency of administration between 2.2% and 16.2%. Prophylactic BT (PRO) was not associated with increased time to HAEC event on adjusted analysis. CONCLUSIONS: Among children with HSCR undergoing primary pull-through surgery, prophylactic BT administration did not demonstrate increased time to first HAEC event. A better-powered study with prophylactic BT is required to determine the effect on HAEC occurrence and timing. LEVEL OF EVIDENCE: Level II (retrospective cohort study).

Variability in Parenteral Nutrition Use in US Children's Hospitals.

BACKGROUND: The variability of parenteral nutrition (PN) use for pediatric inpatients is currently unknown. In this study, we aim to determine the variability in PN use in US children's hospitals and the association of PN initiation with inpatient PN use. METHODS: We performed a retrospective cohort study of children who received PN during an inpatient encounter in US children's hospitals. Hospitals were divided into tertiles based on their rates of PN use: low (<36.9 of 1000 encounters), medium (36.9-51.8 of 1000 encounters), and high (>51.8 of 1000 encounters). Multivariable regression models were developed to assess the associations between hospital PN use and time to PN initiation, PN duration, and encounter length of stay after adjustment for salient patient characteristics. RESULTS: The cohort included 82,142 patients receiving PN, and rates of hospital PN use ranged from 5.9 to 76.7 patients receiving PN per 1000 inpatient encounters. After multivariable adjustment, patients treated at high-use hospitals had a significantly shorter time to initiation of PN compared with low-use hospitals (incident rate ratio [95% CI]: 0.78 [0.69-0.89]; P < .001). There was no significant association between low- and medium- or high-use hospitals regarding PN duration or hospital length of stay. CONCLUSION: Large variation in PN use exists among US children's hospitals. High-use hospitals are more likely to start PN earlier but do not have longer PN duration or encounter length of stay. This variability makes PN use an ideal target for hospital quality improvement efforts to improve adherence to PN evidence-based guidelines.

Early use of autologous blood patch pleurodesis in children is successful in resolving persistent air leaks.

PURPOSE: Experience with autologous blood patch (ABP) pleurodesis for persistent air leak in the pediatric population is limited. The purpose of this series was to describe the experience with ABP at a single tertiary children's hospital. METHODS: A retrospective study was performed of all thoracic procedures done by the pediatric surgery service over three years. RESULTS: Ten patients underwent a total of 17 ABPs. The median age of patients was 12 years (IQR 6-16). The most common underlying reasons for a thoracic procedure included: blebectomy for spontaneous pneumothorax (2), need for lung biopsy (2), resection of known malignant tumor (2), and empyema (2). The median number of days of persistent air leak before first ABP was 7.5 days (IQR 7-10). A second ABP was performed in 6 cases with a third procedure performed in one case. None of the patients developed respiratory compromise during ABP and no infectious complications were identified following ABP. CONCLUSIONS: Our cohort demonstrates that ABP for persistent air leak following thoracic surgery is effective with minimal morbidity in children. We believe ABP can be used early and in patients with a broad range of underlying lung pathology.

Early ileal pouch anal anastomosis for ulcerative colitis in children: Similar outcome to delayed pouch construction despite higher comorbidity.

BACKGROUND: Children with ulcerative colitis (UC) may undergo a staged approach for restorative proctocolectomy and ileal pouch anal anastomosis (IPAA). Previous studies in adults suggest a decreased morbidity with delayed pouch creation, but pediatric studies are limited. We compared outcomes for delayed versus early pouch construction in children. METHODS: Patients with UC undergoing IPAA were selected from the National Surgical Quality Improvement Program Pediatric database from 2012 to 2018. Patients were categorized as early (2-stage) or delayed (3-stage) pouch construction based on Current Procedural Terminology codes. Our primary outcome was any adverse event. We used a multivariable logistic regression model to assess the relationship between timing of pouch creation and adverse events. RESULTS: We identified 371 children who underwent IPAA: 157 (42.3%) had early pouch creation and 214 (57.6%) had a delayed pouch. Those with an early pouch creation were more likely to have exposure to immunosuppressants (11% vs. 5%, p = 0.017) and steroids (30% vs. 10%, p < 0.001) at the time of surgery. After controlling for patient characteristics, there were no significant differences in adverse events between the two groups. CONCLUSIONS: Children undergoing early pouch creation have increased exposure to steroids and immune suppressants; nevertheless, no differences in adverse events were identified. LEVEL OF EVIDENCE: II.

Breast Cancer Knowledge Assessment of Health Workers in Ibadan, Southwest Nigeria.

PURPOSE: Breast cancer is the most common cancer among women, and in low- to middle-income countries late-stage diagnosis contributes to significant mortality. Previous research at the University College Hospital, a tertiary hospital in Ibadan, Nigeria, on social factors contributing to late diagnosis revealed that many patients received inappropriate initial treatment. METHODS: The level of breast cancer knowledge among health practitioners at various levels of the health system was assessed. We developed a tool tailored to local needs to assess knowledge of symptoms, risk factors, treatments, and cultural beliefs. The recruitment included doctors, nurses, and pharmacists in public hospitals, physicians and pharmacists in private practice, nurses and health care workers from primary health care centers, community birth attendants, and students in a health care field from state schools. RESULTS: A total of 1,061 questionnaires were distributed, and 725 providers responded (68%). Seventy-eight percent were female, and > 90% were Yoruba, the dominant local ethnic group. The majority were Christian, and 18% were Muslim. Median knowledge score was 31 out of 56, and the differences in scores between health care worker types were statistically significant (P < .001). Nearly 60% of the participants believed breast cancer is always deadly. More than 40% of participants believed that keeping money in the bra causes breast cancer, and approximately 10% believed that breast cancer is caused by a spiritual attack. CONCLUSION: Our questionnaire revealed that, even at the tertiary care level, significant gaps in knowledge exist, and knowledge of breast cancer is unacceptably low at the level of community providers. In addition to efforts aimed at strengthening health systems, greater knowledge among community health care workers has the potential to reduce delays in diagnosis for Nigerian patients with breast cancer.

Impact of consolidation of cases on post-operative outcomes for index pediatric surgery cases.

BACKGROUND: The effect of the consolidation of neonatal pediatric surgical cases to limited surgeons within a hospital is unknown. We elected to model the distribution of complex neonatal procedures using an economic measure of market concentration, the Herfindahl-Hirschmann Index (HHI), and study its effect on outcomes of index pediatric surgical operations. METHODS: We used data from 49 US children's hospitals between 2007 and 2017 for the following procedures: congenital diaphragmatic hernia repair (CDH), esophageal atresia and tracheoesophageal fistula repair (EA/TEF), and pull-through for Hirschsprung disease (HD). Mixed effects logistic regression modeling was used to adjust for salient patient characteristics to determine the effect of HHI on in-hospital mortality, condition-specific one-year re-operation, and one-year unplanned readmissions. RESULTS: A total of 2270 infants were identified who underwent surgery for the three conditions of interest. On multivariable analysis, increasing HHI was not associated with differences in mortality or condition-specific re-operation within the first year. A decrease in the number of unplanned readmissions at highly concentrated centers was seen for HD (RR 0.8 CI (0.69-0.97), p = 0.02) and CDH (RR 0.4 CI (0.28-0.71), p < 0.001). CONCLUSIONS: Pediatric surgical specialization did not affect mortality or condition-specific re-operation. However, it did decrease the number of unplanned readmissions following CDH repairs and pull-throughs for HD. STUDY DESIGN: Retrospective Cohort Study. LEVEL OF EVIDENCE: Level II.

Implementation of a Quality Improvement Initiative to Decrease Opioid Prescribing in General Surgery.

BACKGROUND: There is increasing need to avoid excess opioid prescribing after surgery. We prospectively assessed overprescription in our hospital system and used these data to design a quality improvement intervention to reduce overprescription. MATERIALS AND METHODS: Beginning in January 2017, an e-mail-based survey to assess the quantity of opioids used postoperatively as well as patient-reported pain control was sent to all surgical patients in a 23-hospital system. In January 2018, as a quality improvement initiative, guidelines were given to surgeons based on patient consumption data. Prescription and consumption were then tracked prospectively. Wilcoxon signed-rank, analysis of variance, and Cuzick trend tests were used to assess for overprescription and changes over time in opioid prescribing and consumption. RESULTS: We included 2239 patients in our cohort. The amount prescribed (median [IQR]: 30 [24-45] versus 18 [12-30], P < 0.001) and consumed (median [IQR]: 12 [7-20] versus 8 [3-15], P < 0.001) each decreased between the first and last quarter studied. Academic hospitals prescribed fewer opioids than nonacademic hospitals (median [IQR]: 24[15-40] versus median [IQR]: 30 [20-45], P < 0.001). There was no difference in the quantity of opioids consumed between patients treated at academic and nonacademic facilities (median [IQR]: 10[3-19] versus 10.5 [4-20], P = 0.08). Patients consumed a median of 42% of the opioids prescribed, and there was no significant trend in the percent consumed over time (P = 0.8). CONCLUSIONS: Patients used far fewer opioids than prescribed after common adult general surgery procedures. When surgeons were provided with patient consumption data, the number of opioids prescribed decreased significantly.

Hirschsprung-associated enterocolitis in children treated at US children's hospitals.

BACKGROUND: The incidence of and risk factors for Hirschsprung's-associated enterocolitis (HAEC) following pull-through have been limited to single institutions studies. We characterized the incidence of, risk factors for, and consequences of post-operative HAEC. METHODS: We identified children with Hirschsprung's Disease (HD) at US Children's Hospitals from 2007 to 2017 with and an associated pull-through operation at less than 1 year of age. HAEC readmissions were identified using ICD9/10 Diagnosis Codes and antibiotic administration. Hierarchical logistic regression models were developed for the risk factors for HAEC after pull-through and effects of recurrent HAEC on HD-related reoperations. RESULTS: We identified 2030 children with HD, and 138 (7%) who had two or more readmissions related to HAEC. The frequency of recurrent HAEC by hospital ranged from 0 to 33%. Pre-operative HAEC, history of central nervous system infection, and congenital neurologic anomalies were associated with increased risk of recurrent HAEC. Recurrent HAEC was associated with HD-specific re-operation (OR 5.2, CI 3.3-8.1, p < 0.001); however, it was not associated with risk of in-hospital mortality (OR 3.3, CI 0.88-12.1, p = 0.08). CONCLUSIONS: HAEC following pull-through occurs in a large proportion of infants with HD and predicts reoperation. Multicenter studies are needed to develop prediction models and treatment protocols for HAEC. LEVEL OF EVIDENCE: II TYPE OF STUDY: Retrospective cohort study.

Opioid Prescribing and Use in Ambulatory Otolaryngology.

OBJECTIVES: The objective of this study was to evaluate surgeon-prescribing patterns and opioid use for patients undergoing common otolaryngology surgeries. We hypothesized that there was little consistency across surgeons in prescribing patterns and that surgeons prescribed significantly more opioids than consumed by patients. METHODS: E-mail-based surveys were sent to all postoperative patients across a 23-hospital system. The survey assessed quantity of opioids consumed postoperatively, patient-reported pain control, and methods of opioid disposal. We compared patient-reported opioid consumption to opioids prescribed based on data in the electronic data warehouse. RESULTS: There was wide variation in prescribing between providers both in the quantity and type of opioids prescribed. Patients used significantly less opioids than they were prescribed (10 vs. 30 tablets, P < 0.001) for both opioid-exposed and opioid-naïve patients. More than 75% of patients had excess opioids remaining. CONCLUSION: Opioids are consistently overprescribed following ambulatory head and neck surgery. Otolaryngologists have an important role in the setting of the national opioid epidemic and should be involved in efforts to reduce excess opioids in their community. LEVEL OF EVIDENCE: 4 Laryngoscope, 130: 1913-1921, 2020.

Prescription vs. consumption: Opioid overprescription to children after common surgical procedures.

BACKGROUND: In the setting of a national opioid epidemic there are concerns about routine overprescription of opioids postoperatively in both children and adults, which introduces excess opioids into the community. PURPOSE: We sought to examine current opioid prescribing practices by surgeons and consumption of prescribed opioids by pediatric surgical patients following discharge. METHODS: Starting in January 2017 we began an emailed survey for all postoperative patients in a 23-hospital system about the opioids they were prescribed and consumed following discharge. They were then asked if their pain was controlled. Responses of pediatric patients (age 10-18) were examined. FINDINGS: Data from 277 patients were analyzed. After surgical procedures, patients were prescribed significantly more opioids (given in hydrocodone 5 mg equivalents) than they consumed: for appendectomy (median 10 vs. 2) cholecystectomy (12 vs. 5), hernia repair (20 vs. 14), tonsillectomy (30 vs. 17), sinus surgery (30 vs. 5), septoplasty (27 vs. 9.5), knee arthroscopy (30 vs. 12.5), open reduction and internal fixation (ORIF) of the hand and wrist (20 vs. 8.5), and ORIF of the foot and ankle (27 vs. 13.5). The majority (84%) of patients agreed or strongly agreed with the statement that their pain was controlled. Of patients with excess opioids, 64% reported keeping them in their home. CONCLUSIONS: Providers prescribed more opioid tablets than were used by patients. Despite using fewer tablets, patients reported good pain control. Current prescribing practices contribute to excess opioids in the community and represent an opportunity to alter the current epidemic. LEVEL OF EVIDENCE: III.

Using Natural Language Processing to improve EHR Structured Data-based Surgical Site Infection Surveillance.

Surgical Site Infection surveillance in healthcare systems is labor intensive and plagued by underreporting as current methodology relies heavily on manual chart review. The rapid adoption of electronic health records (EHRs) has the potential to allow the secondary use of EHR data for quality surveillance programs. This study aims to investigate the effectiveness of integrating natural language processing (NLP) outputs with structured EHR data to build machine learning models for SSI identification using real-world clinical data. We examined a set of models using structured data with and without NLP document-level, mention-level, and keyword features. The top-performing model was based on a Random Forest classifier enhanced with NLP document-level features achieving a 0.58 sensitivity, 0.97 specificity, 0.54 PPV, 0.98 NPV, and 0.52 F0.5 score. We further interrogated the feature contributions, analyzed the errors, and discussed future directions.

Colonic diverticulosis in an infant: A clue to total colonic Hirschsprung disease.

Total colonic aganglionosis is a rare phenotype of Hirschsprung disease (HD). While the diagnosis is generally established within the neonatal period there are reports of delayed presentation. In this case, we describe a 9-month old girl with no previous medical or surgical history who presented with a small bowel obstruction. A contrast enema performed as part of the work up demonstrated right sided colonic diverticula with no other anatomical abnormalities. Surgical intervention was required to manage the obstruction and colonic biopsies were consistent with HD. This case highlights the association of the unusual finding of colonic diverticula with total colonic HD in infants.
