Povidone-iodine intra-abdominal irrigation versus no irrigation in pediatric perforated appendicitis: A secondary economic analysis of a Bayesian randomized controlled trial.

BACKGROUND: A pilot randomized controlled trial (RCT) conducted in children (2-17 â€‹y) with perforated appendicitis demonstrated an 89% probability of reduced intra-abdominal abscess (IAA) rate with povidone-iodine (PVI) irrigation, compared with no irrigation (NI). We hypothesized that PVI also reduced 30-day hospital costs. METHODS: We conducted a retrospective economic analysis of a pilot RCT. Hospital costs, inflated to 2019 U.S. dollars, were obtained for index admissions and 30-day emergency visits and readmissions. Cost differences between groups were assessed using frequentist and Bayesian generalized linear models. RESULTS: We observed a 95% Bayesian probability that PVI reduced 30-day mean total hospital costs ($16,555 [PVI] versus $18,509 [NI]; Bayesian cost ratio: 0.90, 95% CrI, 0.78-1.03). The mean absolute difference per patient was $1,954 less with PVI (95% CI, -$4,288 to $379). CONCLUSIONS: PVI likely reduced the IAA rate and 30-day hospital costs, suggesting the intervention is both clinically superior and cost saving.

Healthcare Utilization Among Infants Discharged From the Neonatal Intensive Care Unit: A Descriptive Cost Analysis.

The cost of readmissions of neonatal intensive care unit (NICU) graduates within 6 months and a year of their life is well-studied. However, the cost of readmissions within 90 days of NICU discharge is unknown. This study's objective was to estimate the overall and mean cost of healthcare use for unplanned hospital visits of NICU graduates within 90 days of discharge A retrospective review of all infants discharged between 1/1/2017 and 03/31/2017 from a large hospital system NICUs was conducted. All unplanned hospital visits (readmissions or stand-alone emergency department (ED) visits) occurring within 90 days post NICU discharge were included. The total and mean cost of unplanned hospital visits were computed and adjusted to 2021 US dollars. The total cost was estimated to be $785 804 with a mean of $1898 per patient. Hospital readmissions accounted for 98% ($768 718) of the total costs and ED visits for 2% ($17 086). The mean cost per readmission and stand-alone ED visit were $25 624 and $475 respectively. The highest mean total cost of unplanned hospital readmission was noted in extremely low birth weight infants ($25 295). Interventions targeted to reduce hospital readmissions after NICU discharge have the potential to significantly reduce healthcare costs for this patient population.

Impact of Cryoanalgesia Use During Minimally Invasive Pectus Excavatum Repair on Hospital Days and Total Hospital Costs Among Pediatric Patients.

INTRODUCTION: Surgical repair of pectus excavatum is a painful procedure requiring multimodal pain control with historically prolonged hospital stay. This study aimed to evaluate the impact of cryoanalgesia during minimally invasive repair of pectus excavatum (MIRPE) on hospital days (HDs), total hospital costs (HCs), and complications. We hypothesized that cryoanalgesia would be associated with reduced HDs and total HCs with no increase in post-operative complications. METHODS: We conducted a retrospective review of pediatric patients who underwent MIRPE from 2011 to 2021. MIRPE details and post-operative outcomes within 90 days were abstracted. Total HDs included the index MIRPE admission and readmissions within 90 days. HCs were obtained from the hospital accounting system, retroactively adjusting for medical inflation. Bayesian generalized linear models with neutral prior assuming no effect were used. Differences between treatment groups were assessed using gamma distribution (HDs and HCs) and poisson (post-operative complications). All models used log link and controlled for age, gender, race, and Haller index. RESULTS: Forty-four patients underwent MIRPE during the study period. Cryoanalgesia was utilized in 29 (66%) patients. The probability of a reduction with cryoanalgesia vs. no cryoanalgesia was 99% for HDs (3.0 vs. 5.4 days; Bayesian RR: 0.6, 95% CrI: 0.5-0.8), 89% for HCs ($18,787 vs. $19,667; RR: 0.9, 95% CrI: 0.8-1.1), and 70% for postoperative complications (17% vs 33%; RR: 0.8, 95% CrI: 0.3-1.9). CONCLUSION: Cryoanalgesia use in MIRPE likely reduced HDs, HCs, and post-operative complications. Further research is warranted to confirm these findings in large prospective studies. LEVEL OF EVIDENCE: Level III.

Multicenter Assessment of Cryoanalgesia Use in Minimally Invasive Repair of Pectus Excavatum: A 20-center Retrospective Cohort Study.

OBJECTIVE: To assess the clinical implications of cryoanalgesia for pain management in children undergoing minimally invasive repair of pectus excavatum (MIRPE). BACKGROUND: MIRPE entails significant pain management challenges, often requiring high postoperative opioid use. Cryoanalgesia, which blocks pain signals by temporarily ablating intercostal nerves, has been recently utilized as an analgesic adjunct. We hypothesized that the use of cryoanalgesia during MIRPE would decrease postoperative opioid use and length of stay (LOS). MATERIALS AND METHODS: A multicenter retrospective cohort study of 20 US children's hospitals was conducted of children (age below 18 years) undergoing MIRPE from January 1, 2014, to August 1, 2019. Differences in total postoperative, inpatient, oral morphine equivalents per kilogram, and 30-day LOS between patients who received cryoanalgesia versus those who did not were assessed using bivariate and multivariable analysis. P value <0.05 is considered significant. RESULTS: Of 898 patients, 136 (15%) received cryoanalgesia. Groups were similar by age, sex, body mass index, comorbidities, and Haller index. Receipt of cryoanalgesia was associated with lower oral morphine equivalents per kilogram (risk ratio=0.43, 95% confidence interval: 0.33-0.57) and a shorter LOS (risk ratio=0.66, 95% confidence interval: 0.50-0.87). Complications were similar between groups (29.8% vs 22.1, P =0.07), including a similar rate of emergency department visit, readmission, and/or reoperation. CONCLUSIONS: Use of cryoanalgesia during MIRPE appears to be effective in lowering postoperative opioid requirements and LOS without increasing complication rates. With the exception of preoperative gabapentin, other adjuncts appear to increase and/or be ineffective at reducing opioid utilization. Cryoanalgesia should be considered for patients undergoing this surgery.

Costs associated with postoperative intra-abdominal abscess in pediatric perforated appendicitis: A retrospective cohort study.

BACKGROUND: Intra-abdominal abscess, the most common complication after perforated appendicitis, is associated with considerable economic burden. However, costs of intra-abdominal abscesses in children are unknown. We aimed to evaluate resource utilization and costs attributable to intra-abdominal abscess in pediatric perforated appendicitis. METHODS: A single-center retrospective analysis was performed of children (<18 years) who underwent appendectomy for perforated appendicitis (2013-2019). Hospital costs incurred during the index admission and within 30 postoperative days were obtained from the hospital accounting system and inflated to 2019 USD. Generalized linear models were used to determine excess resource utilization and costs attributable to intra-abdominal abscess after adjusting for confounders. RESULTS: Of 763 patients, 153 (20%) developed intra-abdominal abscesses. Eighty-one patients with intra-abdominal abscesses (53%) underwent percutaneous abscess drainage. Intra-abdominal abscess was independently associated with a nearly 8-fold increased risk of 30-day readmission (adjusted risk ratio, 7.8 [95% confidence interval, 4.7-13.0]). Patients who developed an intra-abdominal abscess required 6.1 excess hospital bed days compared to patients without intra-abdominal abscess (95% confidence interval, 5.3-7.0). Adjusted mean hospital costs for patients with intra-abdominal abscess totaled $27,394 (95% confidence interval, $25,688-$29,101) versus $15,586 (95% confidence interval, $15,102-$16,069) for patients without intra-abdominal abscess. Intra-abdominal abscess was associated with an incremental cost of $11,809 (95% confidence interval, $10,029-$13,588). Hospital room costs accounted for 66% of excess costs. CONCLUSION: Postoperative intra-abdominal abscess nearly doubled pediatric perforated appendicitis costs, primarily due to more hospital bed days and associated room costs. Intra-abdominal abscesses resulted in estimated excess costs of $1.8 million during the study period. Even small reductions in intra-abdominal abscess rates or hospital bed days could yield substantial health care savings.

Is the changing landscape of fellowship recruitment during COVID-19 here to stay?

BACKGROUND: The 2020 Pediatric Surgery (PS) fellowship selection process was heavily impacted by the COVID-19 pandemic. A review of lessons learned can help determine best practices for the future. The purpose of the study was to analyze the virtual interview experience and assess opportunities to improve the post-pandemic fellowship recruitment process. STUDY DESIGN: Using a 28-question survey of Program Directors (PDs) of PS fellowships as well as a 44-question survey of applicants to PS fellowships in the US and Canada, we gathered information on the recruitment process during the COVID-19 pandemic (2020). Dichotomous, multiple choice and open-ended questions about the changes in process, platforms used, format, comparison to on-site interviews and overall satisfaction were used for objective and subjective feedback. RESULTS: A 95% participation rate was recorded for the PD survey. 24 out of 55 programs (44%) changed their on-site interviews to virtual format due to the pandemic. Most PDs described their overall impression of virtual interviews as satisfactory (66%, 16/24) and did not have an impact on the applicant's success in the match (35/54; 65%). About 50% of PDs preferred to have on-site interviews with virtual screening in the future. While the participation rate from applicants was much less (26 of 70), responses confirmed our survey results. Majority preferred on-site interviews (17/26), 6 of which preferred virtual screening followed by on-site interviews. CONCLUSION: Components of virtual screening and interviews were found to have benefits financially and from both time and stress perspectives, and thus might survive past the pandemic.

Early discharge after nonoperative management of intussusception is both safe and cost-effective.

BACKGROUND/PURPOSE: We implemented a quality improvement (QI) initiative to safely reduce post-reduction monitoring for pediatric patients with ileocolic intussusception. We hypothesized that there would be decreased length of stay (LOS) and hospital costs, with no change in intussusception recurrence rates. METHODS: A retrospective cohort study was conducted of pediatric ileocolic intussusception patients who underwent successful enema reduction at a tertiary-care pediatric hospital from January 2015 through June 2020. In September 2017, an intussusception management protocol was implemented, which allowed discharge within four hours of reduction. Pre- and post-QI outcomes were compared for index encounters and any additional encounter beginning within 24 h of discharge. An economic evaluation was performed with hospital costs inflation-adjusted to 2020 United States Dollars ($). Cost differences between groups were assessed using multivariable regression, adjusting for Medicaid and transfer status, P < 0.05 significant. RESULTS: Of 90 patients, 37(41%) were pre-QI and 53(59%) were post-QI. Patients were similar by age, sex, race, insurance status, and transfer status. Pre-QI patients had a median LOS of 23.4 h (IQR: 16.1-34.6) versus 9.3 h (IQR 7.4-14.2) for post-QI patients, P < 0.001. Mean total costs per patient in the pre-QI group were $3,231 (95% CI, $2,442-$4,020) versus $1,861 (95% CI, $1,481-$2,240) in the post-QI group. The mean absolute cost difference was $1,370 less per patient in the post-QI group (95% CI, [-$2,251]-[-$490]). Five patients had an additional encounter within 24 h of discharge [pre-QI: 1 (3%) versus post-QI: 4 (8%), p = 0.7] with four having intussusception recurrence [pre-QI: 1 (3%) versus post-QI: 3 (6%), p = 0.6]. CONCLUSIONS: Implementation of a quality improvement initiative for the treatment of pediatric intussusception reduced hospital length of stay and costs without negatively affecting post-discharge encounters or recurrence rates. Similar protocols can easily be adopted at other institutions. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective comparative treatment study.

Variability in opioid prescribing practices, knowledge, and beliefs: A survey of providers caring for pediatric surgical patients.

BACKGROUND/PURPOSE: Comprehensive opioid stewardship programs require collective stakeholder alignment and proficiency. We aimed to determine opioid-related prescribing practices, knowledge, and beliefs among providers who care for pediatric surgical patients. METHODS: A single-center, cross-sectional survey was conducted of attending physicians, residents, and advanced practice providers (APPs), who managed pediatric surgical patients. RESULTS: Of 110 providers surveyed, 75% completed the survey. Over half of respondents (n = 43, 52%) reported always/very often prescribing opioids at discharge, with residents reporting the highest rate (66%). Provider types had varying prescribing patterns, including what types of opioids and non-opioids they prescribed. There was a lack of formal training, particularly among residents, of which only 42% reported receiving formal opioid prescribing education. Finally, although only 28% of providers felt that the opioid epidemic affects children, 48% believed pediatric providers' prescribing patterns contributed to the opioid epidemic as a whole, and 80% reported changing their prescribing practices in response. CONCLUSIONS: Significant variability exists in opioid prescribing practices, knowledge, and beliefs among providers who care for pediatric surgical patients. Effective opioid stewardship requires comprehensive policies, pediatric specific guidelines, and education for all providers caring for children to align provider proficiency and optimize prescribing patterns.

Fractional Limb Volume in Spina Bifida Fetuses as an Assessment Tool for Postnatal Ambulation.

BACKGROUND: Prenatal fractional limb volume (FLV) can be used to assess muscle atrophy in fetuses with myelomeningocele. OBJECTIVE: We hypothesize that FLV in fetal myelomeningocele (fMMC) repair is different from postnatal repair (PNR). Assessing intrauterine muscle development can predict ambulation. METHODS: A prospective observational study was performed from July 2012 to April 2016. Demographics, clinical outcomes, and FLV of the fetal thigh were assessed by ultrasound. Ambulation videos were collected from patients over 30 months of age. FLV was compared between the fMMC and PNR groups and between ambulators and non-ambulators. Two-sample t test, ANOVA, Spearman's rho correlation, and Bland-Altman plots were used for analysis. A p value <0.05 was used for statistical significance. RESULTS: Fifty-nine patients were included, 24 had fMMC and 35 had PNR. Videos were obtained in 47 cases (73%). There was no difference in baseline demographics between the groups. There was no significant change in the fMMC group between the FLV at initial presentation and the repeat at 34 weeks gestation (54.5 ± 28.2 and 62.2% ± 16.4; p = 0.6). In contrast, the FLV in the PNR decreased between the initial evaluation and the repeat at 34 weeks (54.1 ± 27.7 to 35.8 ± 34.1%; p = 0.04). FLV at 34 weeks gestation was higher in the fMMC group as compared to the PNR group (62.2 ± 16.4 vs. 35.8 ± 34.1%; p = 0.02). There was no difference in FLV between ambulators and non-ambulators either at initial evaluation (p = 0.8) or at 34 weeks gestation (p = 0.6). CONCLUSION: Lower FLV in the PNR group compared to fMMC may suggest in utero muscle atrophy. No correlation was seen between FLV and subsequent ambulation; however, future larger studies may be needed.

The Impact of Sociodemographic and Hospital Factors on Length of Stay Before and After Pyloromyotomy.

BACKGROUND: The aim of the study was to determine whether racial or ethnic and insurance disparities exist in pre- and post-operative length of stay (LOS) in patients with hypertrophic pyloric stenosis (HPS). MATERIALS AND METHODS: The Healthcare Cost and Utilization Project Kid's Inpatient Database database (years 2006, 2009, and 2012) was analyzed for patients aged <1 y with HPS with a primary procedure of pyloromyotomy. Multivariate logistic regression was performed to determine the association between race or ethnicity and insurance status with the primary outcomes of prolonged pre- and post-operative LOS (defined as >1 d). Odds ratios (ORs) and 95% confidence intervals (CIs) were tabulated using SPSS v24. RESULTS: A total of 13,706 cases were identified: 8503 (62%) non-Hispanic whites, 3143 (23%) Hispanics, 1007 (7%) non-Hispanic blacks (NHB), and 1053 (8%) non-Hispanic other race or ethnicity. NHB and Hispanics were 45% and 37%, respectively, more likely to have prolonged preoperative LOS compared with non-Hispanic whites (OR = 1.45, 95% CI: 1.19-1.77; OR = 1.37, 95% CI: 1.18-1.60, respectively). Children with public insurance had 21% increased odds of increased preoperative LOS (OR = 1.21, 95% CI: 1.06-1.38). All minority groups had increased odds of postoperative LOS (NHB OR 1.36, 95% CI: 1.17-1.54; Hispanic OR 1.14, 95% CI: 1.03-1.26; NHO OR 1.31, 95% CI: 1.15-1.51). CONCLUSIONS: We conclude that NHB, Hispanics, and other race or ethnicity were more likely to have prolonged pre- and post-operative LOS. In addition, children with public insurance were more likely to have prolonged preoperative LOS. Further work is needed to better characterize and eliminate disparities in the management and outcomes of children with HPS.

Preventing patient harm via adverse event review: An APSA survey regarding the role of morbidity and mortality (M&M) conference.

INTRODUCTION: Peer-review endeavors represent the continual learning environment critical for a culture of patient safety. Morbidity and mortality (M&M) conferences are designed to review adverse events to prevent future similar events. The extent to which pediatric surgeons participate in M&M, and believe M&M improves patient safety, is unknown. METHODS: A cross-sectional survey of the American Pediatric Surgical Association membership was conducted to evaluate participation in and perception of M&M conferences. Closed and open-ended questions were provided to gauge participation and perceptions of M&M effectiveness. Standard frequency analyses and tests of associations between M&M program attributes and surgeons' perceptions of effectiveness were performed. RESULTS: The response rate was 38% (353/928). Most surgeons (85%) reported that they always participate in M&M, but only 64% believe M&M is effective in changing practice or prevention of future adverse events. Effective M&Ms were more likely to emphasize loop closure, multidisciplinary participation, standardized assessment of events, and connection to quality improvement efforts. CONCLUSIONS: Most pediatric surgeons participate in M&M, but many doubt its effectiveness. We identified attributes of M&M conferences that are perceived to be effective. Further investigation is needed to identify how to optimally utilize peer-review programs to prevent adverse events and improve patient safety. LEVEL OF EVIDENCE: V.

Are we missing the near misses in the OR?-underreporting of safety incidents in pediatric surgery.

BACKGROUND: Electronic hospital variance reporting systems used to report near misses and adverse events are plagued by underreporting. The purpose of this study is to prospectively evaluate directly observed variances that occur in our pediatric operating room and to correlate these with the two established variance reporting systems in our hospital. MATERIALS AND METHODS: Trained individuals directly observed pediatric perioperative patient care for 6 wk to identify near misses and adverse events. These direct observations were compared to the established handwritten perioperative variance cards and the electronic hospital variance reporting system. All observations were analyzed and categorized into an additional six safety domains and five variance categories. The chi-square test was used, and P-values < 0.05 were considered statistically significant. RESULTS: Out of 830 surgical cases, 211 were audited by the safety observers. During this period, 137 (64%) near misses were identified by direct observation, while 57 (7%) handwritten and 8 (1%) electronic variance were reported. Only 1 of 137 observed events was reported in the handwritten variance system. Five directly observed adverse events were not reported in either of the two variance reporting systems. Safety observers were more likely to recognize time-out and equipment variances (P < 0.001). Both variance reporting systems and direct observation identified numerous policy and process issues. CONCLUSIONS: Despite multiple reporting systems, near misses and adverse events remain underreported. Identifying near misses may help address system and process issues before an adverse event occurs. Efforts need to be made to lessen barriers to reporting in order to improve patient safety.

The digital divide in adoption and use of mobile health technology among caregivers of pediatric surgery patients.

PURPOSE: The purpose of this study was to identify mobile Health (mHealth) technology utilization among caregivers of pediatric surgery patients. METHODS: We provided a modified version of the 2012 mobile health survey from the Pew Research Center to English and Spanish-speaking caregivers of children aged <18years presenting to pediatric surgical outpatient clinics from June to July of 2016. RESULTS: A total of 171 caregivers completed the survey and included 57 (34%) whites, 30 (18%) blacks, 75 (44%) Hispanics, and 6 (4%) other races. Among these, 160 (94%) were smartphone owners. mHealth users were identified as individuals who used their phone to look up health information online, receive text updates from healthcare providers or pharmacists, or use any health-related smartphone applications. On univariate ordered logistic regression, race/ethnicity, primary language, education level, and income quartile were associated with level of mHealth technology use. The majority of responders (n=126, 76%) said that they would be very or moderately interested in trying a new smartphone app related to management of their child's health. CONCLUSION: While the majority of pediatric caregivers are smartphone owners, there are significant racial and socioeconomic differences in mHealth usage. Understanding these differences may be important in identifying barriers to adoption of mHealth technology. LEVEL OF EVIDENCE: Level IV case series with no comparison group.

Approaching zero: Implications of a computed tomography reduction program for pediatric appendicitis evaluation.

PURPOSE: Because of awareness of iatrogenic radiation exposure, there is a national trend of diminishing computed tomography (CT) use for pediatric suspected appendicitis. The purpose of this study was to evaluate the effects of a CT reduction program for evaluation of appendicitis. METHODS: A multidisciplinary group (emergency medicine, radiology, and surgery) at a children's hospital developed a reduction program which included: ultrasound (U/S) first (2012), magnetic resonance imaging (MRI) second (2014), and standardized U/S reports (2016). Imaging modality, negative appendectomy rate, time from first image to incision, and imaging costs were evaluated over time. RESULTS: Of the 571 patients evaluated from 2012 to 2016, there was a significant decrease in CT use and increase U/S and MRI use over the study period (all p<0.01). CT use approached zero in 2016. Time from first image to incision (median 10.7h, IQR 5.6-15.5) and negative appendectomy rate (mean 3.7±0.2%) did not change. Median imaging costs ($88, IQR $52-$169) and radiology percent of total costs (range 0.8%-3.9%) increased over time (both p<0.01). CONCLUSION: Approaching zero CT use for evaluation of pediatric appendicitis is possible through a multidisciplinary protocol without impacting clinical outcomes. However, increased MRI use led to higher costs. Cost-effectiveness of replacing CT with MRI warrants further study. TYPE OF STUDY: Retrospective comparative study. LEVEL OF EVIDENCE: Level III.

Focused assessment with sonography for trauma in children after blunt abdominal trauma: A multi-institutional analysis.

INTRODUCTION: The utility of focused assessment with sonography for trauma (FAST) in children is poorly defined with considerable practice variation. Our purpose was to investigate the role of FAST for intra-abdominal injury (IAI) and IAI requiring acute intervention (IAI-I) in children after blunt abdominal trauma (BAT). METHODS: We prospectively enrolled children younger than 16 years after BAT at 14 Level I pediatric trauma centers over a 1-year period. Patients who underwent FAST were compared with those that did not, using descriptive statistics and univariate analysis; p value less than 0.05 was considered significant. FAST test characteristics were performed using computed tomography (CT) and/or intraoperative findings as the gold standard. RESULTS: Two thousand one hundred eighty-eight children (age, 7.8 ± 4.6 years) were included. Eight hundred twenty-nine (37.9%) received a FAST, 340 of whom underwent an abdominal CT. Ninety-seven (29%) of these 340 patients had an IAI and 27 (7.9%) received an acute intervention. CT scan utilization after FAST was 41% versus 46% among those who did not receive FAST. The frequency of FAST among centers ranged from 0.84% to 94.1%. There was low correlation between FAST and CT utilization (r = -0.050, p < 0.001). Centers that performed FAST at a higher frequency did not have improved accuracy. The test performance of FAST for IAI was sensitivity, 27.8%; specificity, 91.4%; positive predictive value, 56.2%; negative predictive value, 76.0%; and accuracy, 73.2%. There were 81 injuries among the 70 false-negative FAST. The test performance of FAST for IAI-I was sensitivity, 44.4%; specificity, 88.5%; positive predictive value, 25.0%; negative predictive value, 94.9%; and accuracy, 85.0%. Fifteen children with a negative FAST received acute interventions. Among the 27 patients with true positive FAST examinations, 12 received intervention. All had an abnormal abdominal physical examination. No patient underwent intervention before CT scan. CONCLUSION: As currently used, FAST has a low sensitivity for IAI, misses IAI-I and rarely impacts management in pediatric BAT. LEVEL OF EVIDENCE: Prognostic and epidemiologic study, level II; diagnostic tests or criteria study, level II; therapeutic/care management study, level III.

The Impact of Socioeconomic Status on Appendiceal Perforation in Pediatric Appendicitis.

OBJECTIVE: To assess the impact of socioeconomic status (SES) on pediatric appendicitis outcomes using the validated Agency for Healthcare Research and Quality (AHRQ) SES Index and incorporating block-group data. STUDY DESIGN: We reviewed all patients <18 years old who underwent appendectomy for acute appendicitis from 2009-2013 at our institution. Patient addresses were geocoded and linked to 2010 US Census SES block-group data to determine composite AHRQ SES Index scores based on 7 publically reported SES variables. The primary outcome was appendiceal perforation, and the impact of SES scores, age, race, and insurance status on perforation rates were assessed through regression analyses. RESULTS: Of 1501 patients, 510 (34%) had perforated appendicitis. On bivariate analysis, components of the SES Index associated with an increased perforation rate included lower household income, lower percentage of adults with college education, and higher percentage of adults with <12th grade education (all P < .05). On multivariate analysis, age ≤ 10 years (OR 1.7, 95% CI 1.4-2.2) and public insurance (OR 1.5, 95% CI 1.2-2.0) were associated with increased odds of perforation. CONCLUSIONS: This study used the AHRQ SES scoring system to evaluate SES and its influence on appendiceal perforation. Among our cohort of pediatric patients, the risk of perforation was multifactorial, and younger age and public insurance were stronger predictors of perforation than SES.

Impact of a 24-hour discharge pathway on outcomes of pediatric appendectomy.

BACKGROUND: Clinical pathways for simple (nonperforated, nongangrenous) appendicitis potentially could decrease hospital length of stay (LOS) through standardization of patient care. Our institution initiated a simple appendicitis pathway for children with the goal of less than 24-hour discharge (same-day discharge, SDD) and evaluated its effectiveness. METHODS: A prospective cohort of pediatric patients (<18 years of age) who underwent appendectomy for simple appendicitis after implementation of a SDD pathway were compared with a historic cohort of similar patients in this same large children's hospital. Primary outcomes included LOS, surgical-site infections, and readmissions. Mann Whitney U test, Fischer exact test, χ(2) test, and logistic regression were used. RESULTS: Between June 2009 and May 2013, 1,382 appendectomies were performed; 794 (57%) were for simple appendicitis (316 prepathway and 478 pathway). Hospital LOS decreased 37% after pathway implementation from a median (interquartile range) of 35 (20-50) hours to 22 (9-55) hours (P < .001). SDD increased from 13% to 58% (P < .001). Infectious complications were unchanged (1.6% vs 1.8%, P = .82), but readmissions increased (1.2% vs 4.2%, P = .02). CONCLUSION: A standardized pathway for simple appendicitis that targets SDD can be achieved in children; however, a slight increase in readmissions was noted. High risk for readmission, cost effectiveness, and generalizability need to be further determined.

Hepatocellular carcinoma survival in uninsured and underinsured patients.

BACKGROUND: The incidence of hepatitis C virus (HCV) and hepatocellular carcinoma (HCC) is increasing. The purpose of this study is to establish baseline survival in a medically-underserved population and to evaluate the effect of HCV seropositivity on our patient population. MATERIALS AND METHODS: We reviewed clinicopathologic parameters from a prospective tumor registry and medical records from the Harris County Hospital District (HCHD). Outcomes were compared using Kaplan-Meier survival analysis and log-rank tests. RESULTS: A total of 298 HCC patients were identified. The median survival for the entire cohort was 3.4 mo. There was no difference in survival between the HCV seropositive and the HCV seronegative groups (3.6 mo versus 2.6 mo, P = 0.7). Patients with a survival <1 mo had a significant increase in αfetoprotein (AFP), international normalized ratio (INR), model for end-stage liver disease (MELD) score, and total bilirubin and decrease in albumin compared with patients with a survival ≥ 1 mo. CONCLUSIONS: Survival for HCC patients in the HCHD is extremely poor compared with an anticipated median survival of 7 mo reported in other studies. HCV seropositive patients have no survival advantage over HCV seronegative patients. Poorer liver function at diagnosis appears to be related to shorter survival. Further analysis into variables contributing to decreased survival is needed.

Thoracoscopic decortication vs tube thoracostomy with fibrinolysis for empyema in children: a prospective, randomized trial.

PURPOSE: Management of empyema has been debated in the literature for decades. Although both primary video-assisted thoracoscopic surgery (VATS) and tube thoracostomy with pleural instillation of fibrinolytics have been shown to result in early resolution when compared to tube thoracostomy alone, there is a lack of comparative data between these modes of management. Therefore, we conducted a prospective, randomized trial comparing VATS to fibrinolytic therapy in children with empyema. METHODS: After Institutional Review Board approval, children defined as having empyema by either loculation on imaging or more than 10,000 white blood cells/microL were treated with VATS or fibrinolysis. Based on our retrospective data using length of postoperative hospitalization as the primary end point, a sample size of 36 patients was calculated for an alpha of .5 and a power of 0.8. Fibrinolysis consisted of inserting a 12F chest tube followed by infusion of 4 mg tissue plasminogen activator mixed with 40 mL of normal saline at the time of tube placement followed by 2 subsequent doses 24 hours apart. RESULTS: At diagnosis, there were no differences between groups in age, weight, degree of oxygen support, white blood cell count, or days of symptoms. The outcome data showed no difference in days of hospitalization after intervention, days of oxygen requirement, days until afebrile, or analgesic requirements. Video-assisted thoracoscopic surgery was associated with significantly higher charges. Three patients (16.6%) in the fibrinolysis group subsequently required VATS for definitive therapy. Two patients in the VATS group required ventilator support after therapy, one of whom required temporary dialysis. No patient in the fibrinolysis group clinically worsened after initiation of therapy. CONCLUSIONS: There are no therapeutic or recovery advantages between VATS and fibrinolysis for the treatment of empyema; however, VATS resulted in significantly greater charges. Fibrinolysis may pose less risk of acute clinical deterioration and should be the first-line therapy for children with empyema.

Resource utilization and outcomes from percutaneous drainage and interval appendectomy for perforated appendicitis with abscess.

OBJECTIVE: Given the perceived technical demands of laparoscopic appendectomy and the expected postoperative morbidity in patients with a well-defined abscess, initial percutaneous drainage has become an attractive option in this patient population. This strategy allows for a laparoscopic appendectomy to be performed in an elective manner at the convenience of the surgeon. However, the medical burden on the patient and on the quality of patient outcomes has not been described in the literature. Therefore, we audited our experience with initial percutaneous drainage followed by laparoscopic interval appendectomy to evaluate the need for a prospective trial. METHODS: After institutional review board approval, a retrospective chart review was performed on all children who presented with perforated appendicitis and a well-defined abscess and were treated by initial percutaneous aspiration/drainage followed by interval appendectomy between January 2000 and September 2006. Continuous variables are listed with standard deviation. RESULTS: There were 52 patients with a mean age of 9.0 +/- 3.9 years and weight of 34.4 +/- 18.8 kg. The mean duration of symptoms at presentation was 8.4 +/- 7.6 days. Percutaneous aspiration only was performed in 2 patients. The mean volume of fluid on initial aspiration/drain placement was 76.3 +/- 81.1 mL. The mean time to appendectomy was 61.9 +/- 25.2 days. The laparoscopic approach was used in 49 patients (94.2%), of which one was converted to an open operation. The mean length of hospitalization after interval appendectomy was 1.4 +/- 1.4 days. A recurrent abscess developed in 17.3% of the patients. Six patients (11.5%) required another drainage procedure. The mean total charge to the patients was $40,414.02. There were 4 significant drain complications (ileal perforation, colon perforation, bladder perforation, and buttock/thigh necrotizing abscess). The child with the ileal perforation after drain placement is the only patient who failed initial nonoperative therapy. CONCLUSIONS: The use of initial percutaneous aspiration/drainage of periappendiceal abscess followed by interval appendectomy is an effective approach. However, this management poses complication risks and uses considerable resources. Therefore, this strategy should be compared with early operation in a prospective trial.
