Intercostal Nerve Cryoablation Reduces Opioid Use and Length of Stay Without Increasing Adverse Events: A Retrospective Cohort Study of 5442 Patients Undergoing Surgical Correction of Pectus Excavatum.

OBJECTIVE: To examine differences in opioid use, length of stay, and adverse events after minimally invasive correction of pectus excavatum (MIRPE) with and without intercostal nerve cryoablation. BACKGROUND: Small studies show that intraoperative intercostal nerve cryoablation provides effective analgesia with no large-scale evaluations of this technique. METHODS: The pediatric health information system database was used to perform a retrospective cohort study comparing patients undergoing MIRPE at children's hospitals before and after the initiation of cryoablation. The association of cryoablation use with inpatient opioid use was determined using quantile regression with robust standard errors. Difference in risk-adjusted length of stay between the cohorts was estimated using negative binomial regression. Odds of adverse events between the two cohorts were compared using logistic regression with a generalized estimating equation. RESULTS: A total of 5442 patients underwent MIRPE at 44 children's hospitals between 2016 and 2022 with 1592 patients treated after cryoablation was introduced at their hospital. Cryoablation use was associated with a median decrease of 80.8 (95% CI: 68.6-93.0) total oral morphine equivalents as well as a decrease in estimated median length of stay from 3.5 [3.2-3.9] days to 2.5 [2.2-2.9] days ( P value: 0.016). Cryoablation use was not significantly associated with an increase in any studied adverse events. CONCLUSIONS: Introduction of cryoablation for perioperative analgesia was associated with decreased inpatient opioid use and length of stay in a large sample with no change in adverse events. This novel modality for perioperative analgesia offers a promising alternative to traditional pain management in thoracic surgery.

Applying machine learning to consumer wearable data for the early detection of complications after pediatric appendectomy.

When children are discharged from the hospital after surgery, their caregivers often rely on subjective assessments (e.g., appetite, fatigue) to monitor postoperative recovery as objective assessment tools are scarce at home. Such imprecise and one-dimensional evaluations can result in unwarranted emergency department visits or delayed care. To address this gap in postoperative monitoring, we evaluated the ability of a consumer-grade wearable device, Fitbit, which records multimodal data about daily physical activity, heart rate, and sleep, in detecting abnormal recovery early in children recovering after appendectomy. One hundred and sixty-two children, ages 3-17 years old, who underwent an appendectomy (86 complicated and 76 simple cases of appendicitis) wore a Fitbit device on their wrist for 21 days postoperatively. Abnormal recovery events (i.e., abnormal symptoms or confirmed postoperative complications) that arose during this period were gathered from medical records and patient reports. Fitbit-derived measures, as well as demographic and clinical characteristics, were used to train machine learning models to retrospectively detect abnormal recovery in the two days leading up to the event for patients with complicated and simple appendicitis. A balanced random forest classifier accurately detected 83% of these abnormal recovery days in complicated appendicitis and 70% of abnormal recovery days in simple appendicitis prior to the true report of a symptom/complication. These results support the development of machine learning algorithms to predict onset of abnormal symptoms and complications in children undergoing surgery, and the use of consumer wearables as monitoring tools for early detection of postoperative events.

A Novel Pediatric Surgery Division Incentive Program Engaging Faculty, Advanced Practice Providers and Staff Around a Single Financial Growth Target.

BACKGROUND: Productivity-based financial incentive programs for faculty are common. We implemented a novel Division wide clinical productivity incentive sharing professional fee collections across faculty, nurses, and staff with half of bonuses reserved to be given out proportionally to achievement of the annual growth target. METHODS: A novel bonus plan was formulated to incentivize collection of professional fees to achieve a 15% annual growth target. The 15% was divided equally between the clinical provider, the responsible provider's center(s) of excellence, and all Division members. 50% of the bonus pool was paid out monthly and the remaining 50% was held for an end of the year payout proportional to achievement of the Divisional professional fee collection annual growth target. PRINCIPAL FINDINGS: During the initial year of the program, overall Division collections and charges grew 30% and 17%, respectively. Average monthly bonuses paid through the new incentive program for faculty, advanced practice providers, and staff were $1,700, $700, and $200, respectively. The program cost $525,000 in additional bonuses over the previous year while the Division saw an increase of 2 million dollars in collections over the previous year. CONCLUSION: A clinical productivity incentive program based upon professional fee collections distributed across faculty, nurses, and staff was feasible and successful in its first year. Collections increased by a significantly higher percentage than charges, we believe collections incentive including support staff will be most useful in practices with lower rates of charge collection. Further study is needed to measure the effects of different components of the program. LEVEL OF EVIDENCE: Level IV. STUDY TYPE: Cost Effectiveness Study.

Discordance between Subjective and Objective Assessments of Activity after Pediatric Appendectomy.

BACKGROUND: Physical activity recovery after pediatric surgery can be assessed using objective measures such as step counts, but practice currently relies on subjective assessment by proxy. It is unclear how subjective and objective assessments of activity relate. We compared caregiver assessment of return to normal physical activity after pediatric appendectomy to step count recovery measured by a Fitbit. METHODS: Pediatric patients who underwent appendectomy were recruited between 2020 and 2022 to be monitored for 21 d with a Fitbit. Patients were grouped by the postoperative day (POD) (7, 14, or 21) their caregiver first reported their activity was "back to normal." Objective return to normal step count was estimated for each group by modeling the inflection point from increasing steps to a plateau. These measures were determined discordant if the subjective report remained outside the modeled 95% confidence interval (CI) for the day the group plateaued. RESULTS: Thirty-nine simple appendicitis and 40 complicated appendicitis patients were recruited. Among simple appendicitis patients, daily steps plateaued on POD 10.8 (95% CI 7.4-14.3), POD 14.0 (95% CI 11.0-17.1), and POD 11.1 (95% CI 6.9-15.3) for the day 7, day 14, and day 21 groups, respectively. Complicated appendicitis groups plateaued on POD 12.8 (95% CI 8.7-16.9), POD 15.2 (95% CI 11.1-19.3), and POD 16.7 (95% CI 12.3-21.0), respectively. Significant discordance was observed between subjective and objective assessments for the day 7 and day 14 simple groups and for the day 7 complicated group. CONCLUSIONS: There was significant discordance between caregiver and accelerometer-assessed activity recovery after pediatric surgery. Development of objective measures of recovery could help standardize assessment of children's recovery after surgery.

Effect of consumer-grade wearable device data on clinician decision making during post-discharge telephone calls after pediatric surgery.

BACKGROUND: During post-discharge telephone calls after pediatric surgery, clinicians must rely on parents/caregivers' assessment of symptoms, which can be inaccurate and often lead to unnecessary emergency department (ED) visits. Physiology (heart rate and physical activity) data from consumer-grade wearables, e.g., Fitbit™, may inform clinical decision making, yet there has been little study of clinician interpretation of this data. This study assessed whether wearable data availability, during simulated telephone calls about postoperative, post-discharge pediatric patients, affects clinician decision making. METHODS: Three simulated telephone call scenarios were presented to a diverse group of pediatric surgery clinicians. The scenarios were based on actual postoperative patients (scenarios 1 and 3 have worrisome symptoms and scenario 2 has non-worrisome symptoms) who had worn a Fitbit™ postoperatively. Each scenario was presented to clinicians (1) without any wearable data; (2) with "concerning" wearable data; and (3) with "reassuring" wearable data. Clinicians rated their likelihood, on a scale of 1-10, of recommending an emergency department (ED) visit for the three instances of each scenario, 10 being definitely ED. RESULTS: Twenty-four (24) clinicians participated in the study. When presented with "reassuring" wearable data, clinicians' likelihood of recommending an ED visit decreased from a median score of 6 to 1 (p < 0.001) for scenario 1 and from 9 to 3 (p < 0.001) for scenario 3. When presented with "concerning" wearable data, the median likelihood of recommending an ED visit increased from 1 to 6 (p = 0.003) for scenario 2. CONCLUSION: This study showed that wearable data affect clinicians' decision making and may be useful in triaging postoperative, post-discharge pediatric patients. LEVEL OF EVIDENCE: V.

Effect of the COVID-19 pandemic on presentation and severity of traumatic injury due to physical child abuse across US children's hospitals.

BACKGROUND: Physical child abuse affects 9 in every 1,000 children in the United States and associated traumatic injuries are often identified by the healthcare system. The COVID-19 pandemic has intensified risk factors for physical child abuse and increased avoidance of the healthcare system. This study examined the effect of the COVID-19 pandemic on presentation and severity of physical child abuse. METHODS: A retrospective, cross-sectional study utilizing the Pediatric Health Information System was performed. An interrupted time series analysis estimated the effect of the COVID-19 pandemic on the number of children <15 years old presenting with physical child abuse to children's hospitals from March 1st to June 30th of 2020 by comparing to those presenting during the same period for years 2016-2019. Hierarchical regression models estimated the effect of the pandemic on likelihood of operative intervention, ICU admission, traumatic brain injury, and mortality. RESULTS: Over the study period, 20,346 physical child abuse encounters were reported by 47 children's hospitals. An interrupted times series model predicted a significant decline in cases due to the effect of the COVID-19 pandemic, representing a deficit of 2,645 cases (p = 0.001). Children presenting during the pandemic had increased odds of requiring ICU admission (p = 0.03) and having a traumatic brain injury in those under 5 years of age (p=<0.001). CONCLUSIONS: The number of children with physical child abuse presenting to children's hospitals significantly declined during the COVID-19 pandemic, but those that did were more likely to be severe. The pandemic may be a risk factor for worse outcomes associated with physical child abuse.

Association of Operative Volume and Odds of Surgical Complication for Patients Undergoing Repair of Pectus Excavatum at Children's Hospitals.

OBJECTIVE: To determine whether procedure-specific provider volume is associated with outcomes for patients undergoing repair of pectus excavatum at tertiary care children's hospitals. STUDY DESIGN: We performed a cohort study of patients undergoing repair of pectus excavatum between January 1, 2013 and December 31, 2019, at children's hospitals using the Pediatric Health Information System database. The main exposures were the pectus excavatum repair volume quartile of the patient's hospital and the pectus excavatum repair volume category of their surgeon. Our primary outcome was surgical complication, identified using International Classification of Diseases, Ninth Revision, Clinical Modification, and International Classification of Diseases, Tenth Revision, Clinical Modification codes from Pediatric Health Information System. Secondary outcomes included high-cost admission and extended length of stay. RESULTS: In total, 7183 patients with an average age of 15.2 years (SD 2.0), 83% male, 74% non-Hispanic White, 68% no comorbidities, 72% private insurance, and 82% from metro areas were analyzed. Compared with the lowest-volume (≤10 cases/year) quartile of hospitals, patients undergoing repair of pectus excavatum at hospitals in the second (>10-18 cases/year), third (>18-26 cases/year), and fourth (>26 cases/year) volume quartiles had decreased odds of complication of OR 0.52 (CI 0.34-0.82), 0.51 (CI 0.33-0.78), and 0.41 (CI 0.27-0.62), respectively. Patients with pectus excavatum who underwent repair by surgeons in the second (>1-5 cases/year), third (>5-10 cases/year), and fourth (>10 cases/year) volume categories had decreased odds of complication of OR 0.91 (CI 0.68-1.20), OR 0.73 (CI 0.51-1.04), and OR 0.55 (CI 0.39-0.76), respectively, compared with the lowest-volume (≤1 case/year) category of surgeons. CONCLUSIONS: Procedure-specific case volume is an important factor when considering providers for elective surgery, even among specialized centers providing comprehensive patient care.
