Interrater reliability of chart-based assessment of functional impairment after pediatric injury using the functional status scale.

BACKGROUND: Functional impairment has been proposed as an alternative outcome for quality improvement in pediatric trauma. The functional status scale (FSS) has been used in studies of injured children, but has only been validated with resource-intensive in-person assessment. Implementation with retrospective chart-based FSS assessment would offer a simplified and scalable alternative. The purpose of this study was to evaluate interrater reliability of retrospective FSS assessment and to identify factors associated with unreliable assessment. METHODS: A retrospective cohort of admissions to a Level I pediatric trauma center between July 2020 and June 2021 was analyzed. Two physicians and two nurse registrars reviewed charts to obtain measures of six FSS domains (mental status, sensory functioning, communication, motor functioning, feeding, and respiratory status) at discharge. Functional impairment was categorized by total FSS scores as good (6,7), mild impairment (8,9), moderate impairment (10-15), severe impairment (16-21), or very severe impairment (>21). Interrater reliability was assessed using intraclass correlation (ICC). Predictors of rater disagreement were evaluated using multivariable logistic regression. RESULTS: The cohort included 443 children with a mean age of 7.4 years (standard deviation, 5.4 years) and median Injury Severity Score of 9 (interquartile range, 5-12). The median time per chart to assess FSS was 2 minutes (interquartile range, 1-2). Thirty-seven patients (8%) had functional impairment at discharge. Interrater reliability was excellent for total FSS score (ICC = 0.87) and good for FSS impairment categorization (ICC = 0.80). Rater disagreement of functional impairment categorization occurred in 14% of cases overall. Higher level of functional impairment and use of therapies (occupational and speech language therapy) were independently associated with more frequent rater disagreement. CONCLUSION: Chart-based FSS assessment is feasible and reliable, but may require more detailed review for patients with higher level of impairment that require allied health therapy. Validation of chart-based assessment is needed before widespread implementation. LEVEL OF EVIDENCE: Prognostic/Epidemiological, Level III.

The cost of emergency care for children across differing levels of emergency department pediatric readiness.

High emergency department (ED) pediatric readiness is associated with improved survival in children, but the cost is unknown. We evaluated the costs of emergency care for children across quartiles of ED pediatric readiness. This was a retrospective cohort study of children aged 0-17 years receiving emergency services in 747 EDs in 9 states from January 1, 2012, through December 31, 2017. We measured ED pediatric readiness using the weighted Pediatric Readiness Score (range: 0-100). The primary outcome was the total cost of acute care (ED and inpatient) in 2022 dollars, adjusted for ED case mix and hospital characteristics. A total of 15 138 599 children received emergency services, including 27.6% with injuries and 72.4% with acute medical illness. The average adjusted per-patient cost by quartile of ED pediatric readiness ranged from $991 (quartile 1) to $1064 (quartile 4) for injured children and $1104-$1217 for medical children. The resulting cost differences were $72 (95% CI: -$6 to $151) and $113 (95% CI: $20-$206), respectively. Receiving emergency care in high-readiness EDs was not associated with marked increases in the cost of delivering services.

Incentive delivery timing and follow-up survey completion in a prospective cohort study of injured children: a randomized experiment comparing prepaid and postpaid incentives.

BACKGROUND: Retaining participants over time is a frequent challenge in research studies evaluating long-term health outcomes. This study's objective was to compare the impact of prepaid and postpaid incentives on response to a six-month follow-up survey. METHODS: We conducted an experiment to compare response between participants randomized to receive either prepaid or postpaid cash card incentives within a multisite study of children under 15 years in age who were hospitalized for a serious, severe, or critical injury. Participants were parents or guardians of enrolled children. The primary outcome was survey response. We also examined whether demographic characteristics were associated with response and if incentive timing influenced the relationship between demographic characteristics and response. We evaluated whether incentive timing was associated with the number of calls needed for contact. RESULTS: The study enrolled 427 children, and parents of 420 children were included in this analysis. Follow-up survey response did not differ according to the assigned treatment arm, with the percentage of parents responding to the survey being 68.1% for the prepaid incentive and 66.7% with the postpaid incentive. Likelihood of response varied by demographics. Spanish-speaking parents and parents with lower income and lower educational attainment were less likely to respond. Parents of Hispanic/Latino children and children with Medicaid insurance were also less likely to respond. We found no relationship between the assigned incentive treatment and the demographics of respondents compared to non-respondents. CONCLUSIONS: Prepaid and postpaid incentives can obtain similar participation in longitudinal pediatric critical care outcomes research. Incentives alone do not ensure retention of all demographic subgroups. Strategies for improving representation of hard-to-reach populations are needed to address health disparities and ensure the generalizability of studies using these results.

Long-Term Outcomes after Pediatric Injury: Results of the Assessment of Functional Outcomes and Health-Related Quality of Life after Pediatric Trauma Study.

BACKGROUND: Disability and impaired health-related quality of life can persist for months among injured children. Previous studies of long-term outcomes have focused mainly on children with specific injury types rather than those with multiple injured body regions. This study's objective was to determine the long-term functional status and health-related quality of life after serious pediatric injury, and to evaluate the associations of these outcomes with features available at hospital discharge. STUDY DESIGN: We conducted a prospective observational study at 7 Level I pediatric trauma centers of children treated for at least 1 serious (Abbreviated Injury Scale severity 3 or higher) injury. Patients were sampled to increase the representation of less frequently injured body regions and multiple injured body regions. Six-month functional status was measured using the Functional Status Scale (FSS) and health-related quality of life using the Pediatric Quality of Life Inventory. RESULTS: Among 323 injured children with complete discharge and follow-up assessments, 6-month FSS score was abnormal in 33 patients (10.2%)-16 with persistent impairments and 17 previously normal at discharge. Increasing levels of impaired discharge FSS score were associated with impaired FSS and lower Pediatric Quality of Life Inventory scores at 6-month follow-up. Additional factors on multivariable analysis associated with 6-month FSS impairment included older age, penetrating injury type, severe head injuries, and spine injuries, and included older age for lower 6-month Pediatric Quality of Life Inventory scores. CONCLUSIONS: Older age and discharge functional status are associated with long-term impairment of functional status and health-related quality of life. Although most seriously injured children return to normal, ongoing disability and reduced health-related quality of life remained 6 months after injury. Our findings support long-term assessments as standard practice for evaluating the health impacts of serious pediatric injury.

Assessment of Non-Routine Events and Significant Physiological Disturbances during Emergency Department Evaluation after Pediatric Head Trauma.

Outcomes following pediatric traumatic brain injury (TBI) are dependent on initial injury severity and prevention of secondary injury. Hypoxia, hypotension, and hyperventilation following TBI are associated with increased mortality. The purpose of this study was to determine the association of non-routine events (NREs) during the initial resuscitation phase with these physiological disturbances. We conducted a video review of pediatric trauma resuscitations of patients with suspected TBI and Glasgow Coma Scale (GCS) scores <13. NREs were rated as "momentary" if task progression was delayed by <1 min and "moderate" if delayed by >1 min. Vital sign monitor data were used to identify periods of significant physiological disturbances. We calculated the association between the rate of overall and moderate NREs per case and the proportion of cases with abnormal vital signs using multi-variate linear regression, controlling for GCS score and need for intubation. Among 26 resuscitations, 604 NREs were identified with a median of 23 (interquartile range [IQR] 17-27.8, range 5-44) per case. Moderate delay NREs occurred in 19 resuscitations (n = 32, median 1 NRE/resuscitation, IQR 0.3-1, range 0-5). Oxygen desaturation and respiratory depression were associated with a greater rate of moderate NREs (p = 0.008, p < 0.001, respectively). We observed no association between duration of hypotension, desaturation, and respiratory depression and overall NRE rate. NREs are common in the initial resuscitation of children with moderate to severe TBI. Episodes of hypoxia and respiratory depression are associated with NREs that cause a moderate delay in task progression. Conformance with resuscitation guidelines is needed to prevent physiological events associated with adverse outcomes following pediatric TBI.

Assessment of primary outcome measures for a clinical trial of pediatric hemorrhagic injuries.

OBJECTIVE: We evaluated the acceptability of the Pediatric Quality of Life Inventory (PedsQL) and other outcomes as the primary outcomes for a pediatric hemorrhagic trauma trial (TIC-TOC) among clinicians. METHODS: We conducted a mixed-methods study that included an electronic questionnaire followed by teleconference discussions. Participants confirmed or rejected the PedsQL as the primary outcome for the TIC-TOC trial and evaluated and proposed alternative primary outcomes. Responses were compiled and a list of themes and representative quotes was generated. RESULTS: 73 of 91 (80%) participants completed the questionnaire. 61 (84%) participants agreed that the PedsQL is an appropriate primary outcome for children with hemorrhagic brain injuries. 32 (44%) participants agreed that the PedsQL is an acceptable primary outcome for children with hemorrhagic torso injuries, 27 (38%) participants were neutral, and 13 (18%) participants disagreed. Several themes were identified from responses, including that the PedsQL is an important and patient-centered outcome but may be affected by other factors, and that intracranial hemorrhage progression assessed by brain imaging (among patients with brain injuries) or blood product transfusion requirements (among patients with torso injuries) may be more objective outcomes than the PedsQL. CONCLUSIONS: The PedsQL was a well-accepted proposed primary outcome for children with hemorrhagic brain injuries. Traumatic intracranial hemorrhage progression was favored by a subset of clinicians. A plurality of participants also considered the PedsQL an acceptable outcome for children with hemorrhagic torso injuries. Blood product transfusion requirement was favored by fewer participants.

Assessment of Nonroutine Events During Intubation After Pediatric Trauma.

BACKGROUND: Intubation in the early postinjury phase can be a high-risk procedure associated with an increased risk of mortality when delayed. Nonroutine events (NREs) are workflow disruptions that can be latent safety threats in high-risk settings and may contribute to adverse outcomes. MATERIALS AND METHODS: We reviewed videos of intubations of injured children (age<17 y old) in the emergency department occurring between 2014 and 2018 to identify NREs occurring between the decision to intubate and successful intubation ("critical window"). RESULTS: Among 34 children requiring intubation, the indications included GCS≤8 (n = 20, 58.8%), cardiac arrest (n = 6, 17.6%), airway protection (n = 5, 14.7%), and respiratory failure (n = 3, 8.8%). The median duration of the "critical window" was 7.5 min (range 1.4-27.5 min), with a median of six NREs per case in this period (range 2-30). Most NREs (n = 159, 61.9%) delayed workflow, with 31 (12.1%) of these delays each lasting more than one minute. Eighty-seven NREs (33.9%) had a potential for harm but did not lead to direct patient harm. The most common NREs directly related to the intubation process were poor positioning for intubation (n = 23, 8.9%) and difficulty passing the endotracheal tube (n = 5, 1.9%), with most being attributed to the anesthesiologist performing the intubation (n = 51, range 0-7). CONCLUSIONS: Workflow disruptions related to nonroutine events were frequent during pediatric trauma intubation and were often associated with delays and potential for patient harm. Interventions for improving the efficiency and timeliness of the critical window should focus on adherence to intubation protocol and improving communication and teamwork related to tasks in this phase.

Assessment of the Need for Immediate Trauma Team Presence for Infants Presenting in Cardiac Arrest.

OBJECTIVES: Out-of-hospital cardiac arrest (OHCA) is rare in infants, with the cause of arrest often unknown upon presentation. Nonaccidental trauma is a potential etiology of OHCA among infants, but its occult presentation makes this etiology challenging to diagnose. In the absence of apparent injuries, identifying the need for trauma team activation is difficult during the initial resuscitation of infants with OHCA. METHODS: We performed a retrospective chart review of infants younger than 1 year old who presented to Children's National Health System from 2012 to 2016 with cardiopulmonary resuscitation in progress. Medical records and the trauma registry were reviewed for relevant resuscitation information. Autopsy records provided the cause and manner of death, contributing factors to death, and evidence of injury. RESULTS: Among 592 infants undergoing resuscitation during the study period, 34 infants (5.7%) presented in cardiac arrest. The average age on presentation was 101.2 days (standard deviation 78.7). Most of the patients (n = 32, 94.1%) died in the emergency department, with none surviving to discharge. Among the 32 infants for whom autopsy records were available, the cause of death was nonaccidental trauma in one patient (3.1%). CONCLUSIONS: Infant OHCA had poor outcomes, with trauma as a rare etiology. In the absence of external signs of injury or known injury mechanism, immediate trauma team presence was not beneficial for these infants during the initial resuscitation phase.

Structured Chart Review: Assessment of a Structured Chart Review Methodology.

BACKGROUND AND OBJECTIVES: Chart reviews are frequently used for research, care assessments, and quality improvement activities despite an absence of data on reliability and validity. We aim to describe a structured chart review methodology and to establish its validity and reliability. METHODS: A generalizable structured chart review methodology was designed to evaluate causes of morbidity or mortality and to identify potential therapeutic advances. The review process consisted of a 2-tiered approach with a primary review completed by a site physician and a short secondary review completed by a central physician. A total of 327 randomly selected cases of known mortality or new morbidities were reviewed. Validity was assessed by using postreview surveys with a Likert scale. Reliability was assessed by percent agreement and interrater reliability. RESULTS: The primary reviewers agreed or strongly agreed in 94.9% of reviews that the information to form a conclusion about pathophysiological processes and therapeutic advances could be adequately found. They agreed or strongly agreed in 93.2% of the reviews that conclusions were easy to make, and confidence in the process was 94.2%. Secondary reviewers made modifications to 36.6% of cases. Duplicate reviews (n = 41) revealed excellent percent agreement for the causes (80.5%-100%) and therapeutic advances (68.3%-100%). κ statistics were strong for the pathophysiological categories but weaker for the therapeutic categories. CONCLUSIONS: A structured chart review by knowledgeable primary reviewers, followed by a brief secondary review, can be valid and reliable.

Self-assessment of team performance using T-NOTECHS in simulated pediatric trauma resuscitation is not consistent with expert assessment.

BACKGROUND: The Trauma NOn-TECHnical Skills (T-NOTECHS) tool has been used to assess teamwork in trauma resuscitation, but its reliability and validity for self-assessment is unknown. Our purpose was to determine the reliability and validity of self-administered T-NOTECHS in pediatric trauma resuscitation. METHODS: Simulated in situ resuscitations were evaluated using T-NOTECHS in real time by experts and immediately afterwards by team members. Reliability was analyzed with linear-weighted kappa and intra-class correlation. T-NOTECHS scores were compared between expert (gold-standard) and self-assessment. RESULTS: Fifteen simulations were examined. T-NOTECHS scores were similar between self- and expert assessment for leadership. Self-assessment scores were higher than expert for the other domains and total composite score. Inter-rater reliability for total score was similar between the two groups, but differences were observed in the domains. CONCLUSIONS: Self-assessment is not interchangeable with expert rating when using T-NOTECHS. Future studies need to determine how self-assessment can be best utilized. LEVEL OF EVIDENCE: Studies of diagnostic accuracy - Level 2.

Use of Payer as a Proxy for Health Insurance Status on Admission Results in Misclassification of Insurance Status among Pediatric Trauma Patients.

The purpose of this study was to quantify health insurance misclassification among children treated at a pediatric trauma center and to determine factors associated with misclassification. Demographic, medical, and financial information were collected for patients at our institution between 2008 and 2010. Two health insurance variables were created: true (insurance on hospital admission) and payer (source of payment). Multivariable logistic regression was used to determine which factors were independently associated with health insurance misclassification. The two values of health insurance status were abstracted from the hospital financial database, the trauma registry, and the patient medical record. Among 3630 patients, 123 (3.4%) had incorrect health insurance designation. Misclassification was highest in patients who died: 13.9 per cent among all deaths and 30.8 per cent among emergency department deaths. The adjusted odds of misclassification were 6.7 (95% confidence interval: 1.7, 26.6) among patients who died and 16.1 (95% confidence interval: 3.2, 80.77) among patients who died in the emergency department. Using payer as a proxy for health insurance results in misclassification. Approaches are needed to accurately ascertain true health insurance status when studying the impact of insurance on treatment outcomes.

Recent national trends in the use of adolescent inpatient bariatric surgery: 2000 through 2009.

OBJECTIVES: To determine the current rate of inpatient bariatric surgical procedures among adolescents and to analyze national trends of use from 2000 to 2009. DESIGN: Retrospective cross-sectional study. SETTING: Discharge data obtained from the Healthcare Cost and Utilization Project Kids' Inpatient Database, 2000 through 2009. PARTICIPANTS: Adolescents (defined herein as individuals aged 10-19 years) undergoing inpatient bariatric procedures. INTERVENTION: Inpatient bariatric surgery. MAIN OUTCOME MEASURES: The primary outcome measure was the national population-based bariatric procedure rate. The secondary outcome measures were trends in procedure rates and type, demographics, complication rate, length of stay, and hospital charges from 2000 through 2009. RESULTS: The inpatient bariatric procedure rate increased from 0.8 per 100 000 in 2000 to 2.3 per 100 000 in 2003 (328 vs 987 procedures) but did not change significantly in 2006 (2.2 per 100 000) or 2009 (2.4 per 100 000), with 925 vs 1009 procedures. The use of laparoscopic adjustable gastric banding approached one-third (32.1%) of all procedures by 2009. The cohort was predominantly female and older than 17 years. The prevalence of comorbidities increased from 2003 (49.3%) to 2009 (58.6%) (P = .002), while the complication rate remained low and the in-hospital length of stay decreased by approximately 1 day (P < .001). Increasing numbers of patients had Medicaid as their primary payer source; however, most (68.3% in 2009) had private insurance. CONCLUSIONS: Despite the worsening childhood obesity epidemic, the rate of inpatient bariatric procedures among adolescents has plateaued since 2003. The predominant procedure type has changed to minimally invasive techniques, including laparoscopic adjustable gastric banding and laparoscopic Roux-en-Y gastric bypass. Trends show low complication rates and decreasing length of stay, despite increasing comorbid conditions among patients.

Assessment of workload during pediatric trauma resuscitation.

BACKGROUND: Trauma resuscitations are high-pressure, time-critical events during which health care providers form ad hoc teams to rapidly assess and treat injured patients. Trauma team members experience varying levels of workload during resuscitations resulting from the objective demands of their role-specific tasks, the circumstances surrounding the event, and their individual previous experiences. The goal of this study was to determine factors influencing workload experienced by trauma team members during pediatric trauma resuscitations. METHODS: Workload was measured using the National Aeronautics and Space Administration Task Load Index (TLX). TLX surveys were administered to four trauma team roles: charge nurse, senior surgical resident (surgical coordinator), emergency medicine physician, and junior surgical resident or nurse practitioner (bedside clinician). A total of 217 surveys were completed. Univariate and multivariate statistical techniques were used to examine the relationship between workload and patient and clinical factors. RESULTS: Bedside clinicians reported the highest total workload score (208.7), followed by emergency medicine physicians (156.3), surgical coordinators (144.1), and charge nurses (129.1). Workload was higher during higher-level activations (235.3), for events involving intubated patients (249.0), and for patients with an Injury Severity Score greater than 15 (230.4) (p, 0.001 for all). When controlling for potential confounders using multiple linear regression, workload was increased during higher level activations (79.0 points higher, p = 0.01) and events without previous notification (38.9 points higher, p = 0.03). Workload also remained significantly higher for the bedside clinician compared with the other three roles (p ≤ 0.005 for all). CONCLUSION: Workload during pediatric trauma resuscitations differed by team role and was increased for higher-level activations and events without previous notification. This study demonstrates the validity of the TLX as a tool to measure workload in trauma resuscitation. LEVEL OF EVIDENCE: Prognostic study, level II.

Socioeconomic disparities in infant mortality after nonaccidental trauma: a multicenter study.

BACKGROUND: While disparities in abuse-related mortality between minority and white infants have been reported, the influence of socioeconomic status on outcome has not been evaluated. The goal of this study was to determine the impact of socioeconomic status and race on outcomes for abused infants using multiinstitutional data. METHODS: Data on infants (<12 months old) with abusive injuries over a 5-year period were obtained from nine U.S. pediatric trauma centers. Demographics, insurance status, Injury Severity Scores, Glasgow Coma Scale scores, median household income and outcomes were recorded. Logistic regression was used to evaluate the impact of race, income and insurance status on mortality. RESULTS: There were 867 patients identified with a mortality of 8.8%. Patients without private insurance had a 3.8 times greater odds (give 95% confidence interval) of dying. Those in the lower three quartiles of income also had a higher odds of death even after controlling for race, injury severity, and Glasgow Coma Scale. Although African American infants had a higher overall mortality than whites (11.2% vs. 7.8%, p = 0.14), race was not an independent predictor of mortality (p = 0.98). CONCLUSIONS: There are significant differences in mortality among abused infants associated with insurance status and income even after controlling for injury severity. These associations show a need to better understand and address socioeconomic variations in outcome.

Pediatric surgery workforce: supply and demand.

INTRODUCTION: Recent studies report a shortage of pediatric surgeons in the United States. We surveyed members of the American Pediatric Surgical Association (APSA) to estimate current workforce and demand and to provide data for workforce planning. METHODS: We conducted a survey of 849 APSA members to provide workforce data on their communities as follows: the number of active, retired, or inactive APSA surgeons; non-APSA fellowship graduates; surgeons without accredited fellowship training; and the estimated demand for additional pediatric surgeons. Internet search engines identified surgeons and practices offering pediatric surgical services. The US Census Metropolitan Statistical Areas (MSAs) defined service areas with populations of 100,000 or more. RESULTS: Of 137 MSAs with APSA members in practice, we obtained data from 113 (83%), with 247 (29%) of 849 surgeons responding. We estimate that the current pediatric surgical workforce consists of 1150 surgeons, with APSA members in active practice (60%) forming the single largest group, followed by general surgeons (21%). The percentage of active APSA surgeons was greater than the percentage of general surgeons in the 50 largest MSAs (76% vs 2%, respectively), whereas the opposite was observed in the smaller MSA ranked more than 51 in population (37% vs 46%, respectively). American Pediatric Surgical Association respondents estimated a national demand for 280 additional pediatric surgeons. Active APSA surgeons plan to delay retirement (8% of respondents) because it would leave their group or community shorthanded; 2% reported that retirement would leave the community without a pediatric surgeon. DISCUSSION: Workforce shortage in pediatric surgery is a problem of number and distribution. Incentives to direct trainees to underserved areas are needed. General surgeons provide pediatric services in many communities. Surgical training should include additional training in pediatric surgery.

Clinical and financial characteristics of pediatric surgery practices.

UNLABELLED: Pediatric surgical practices face many challenges. We wanted to define the clinical practice and financial support among different types of practices as follows: academic, private practice, and employed. METHODS: This study involved an Internet survey of members of the American Pediatric Surgical Association (APSA), comparisons using chi(2) and paired t test analyses. RESULTS: The response rate was 28.7% (233/811), 145 academic, 48 private, and 40 employed. More than 90% received partial to full financial hospital support. Only 7.3% received no outside support, most frequently those in private practices (16.7%; P = .016). More than 90% had resident or fellow coverage. Nearly all practices covered newborn conditions and solid tumors, with differences in pediatric trauma, patent ductus arteriosus, and urologic condition. Transfer out of community was low but increased for specific conditions during the respondents' absence, from 0.4% to 5.2% to 3.4% to 6.9% (P = .001-0.003). A minority of respondents noted that nonpediatric surgeons treated selected pediatric conditions in their communities as follows: inguinal hernia (38.4%), umbilical hernia (42.6%), abscesses (37.5%), and trauma (36.6%). Pediatric surgeons shared call within their group in 86.3%, whereas 5.6% took call alone. Many restricted call by excluding trauma (37.2%), soft tissue infections or appendectomies (21.3% for both), and older children (>12 years, 23.8%). Nearly one fifth (18.9%) expressed interest in having an APSA surgeon serve as a locum tenens in their practices. DISCUSSION: Many pediatric surgeons receive both financial and in-kind subsidies. Although they cover a wide breadth of surgical conditions, many limit the conditions that they treat to reduce call responsibilities. The workforce shortage in pediatric surgery creates call coverage problems that may affect up to 8% of US practices.

Increasing prevalence of gastroschisis repairs in the United States: 1996-2003.

PURPOSE: Local and state registries have shown recent increases in the prevalence of gastroschisis in the United States and abroad. The purpose of this study was to use a nationally representative database to identify national trends in the prevalence of gastroschisis repairs. METHODS: Records of infants undergoing gastroschisis repair were identified in the Nationwide Inpatient Sample from 1996 to 2003. Birth data were obtained from the National Center for Health Statistics and used to calculate the rate of procedures/live births stratified by US census region. Survey statistics were used to account for the sampling design of the Nationwide Inpatient Sample database. RESULTS: Between 1996 and 2003, a total of 9459 gastroschisis repairs were performed in the United States (3 procedures for every 10,000 births). A significant increase in the population-based rate of these procedures was observed in each census regions and nationwide. A twofold higher procedure rate was observed in 2003 than in 1996 (rate ratio, 2.0; 95% confidence interval, 1.1-2.9; P < .001). No significant change in unadjusted hospital mortality was observed regionally or nationally. CONCLUSIONS: The population-based rate of gastroschisis repairs significantly increased regionally and nationwide between 1996 and 2003, paralleling recent trends described at the local and state level.

Evaluation of race and insurance status as predictors of undergoing laparoscopic appendectomy in children.

OBJECTIVE: The objective of this study was to determine the relationship of race and socioeconomic factors and the method used for appendectomies in children (open vs. laparoscopic). SUMMARY BACKGROUND DATA: Previous studies have shown racial and insurance-related differences associated with the management of appendicitis in adults. It is not known whether these differences are observed in children. METHODS: Children (<15 years) undergoing appendectomy from 1996 to 2002 were identified in the Nationwide Inpatient Sample. Severity of appendicitis and underlying chronic illnesses were determined by ICD-9 codes. Hospital characteristics evaluated included teaching status and location, children's hospital status, and volume of appendectomies. Hierarchical unadjusted and risk-adjusted logistic regression analyses were performed. RESULTS: Among 72,189 children undergoing an appendectomy for appendicitis, 11,714 (16%) underwent a laparoscopic appendectomy. Multivariate analysis showed that whites were more likely to undergo a laparoscopic appendectomy than blacks (odds ratio, 1.14; 95% CI, 1.03-1.25, P = 0.01) but not other races. A significant interaction between payer source and children's hospital designation was observed, with the odds of children with private insurance undergoing laparoscopic appendectomy being significantly higher than those without private insurance at nonchildren's hospitals but not at children's hospitals. CONCLUSIONS: There are significant racial and insurance-related differences in use of laparoscopic appendectomy in children that are most evident at nonchildren's hospitals. These findings provide evidence that factors at hospitals dedicated to children may lead to better access to new technologies.

The effect of surgeon volume and hospital characteristics on in-hospital outcome after ureteral reimplantation in children.

The aim of this study was to examine the association between surgeon and hospital characteristics on in-hospital outcome after ureteral reimplantation in children. Patients<18 years undergoing vesicoureteral reimplantation (n=3,109) were identified in Kids' Inpatient Database, an administrative database containing discharge records from 27 states during 2000 in the US. Based on patient volume in 2000, surgeons were designated as low volume (<11 procedures), medium volume (11-20 procedures) and high volume (>20 procedures) surgeons. Length of stay and hospital charges were analyzed using multivariate linear regression analysis. A significant association between shorter length of stay and higher surgeon volume (p=0.02) was observed that was independent of children's hospital status, hospital volume and other hospital characteristics. Length of stay was 20% shorter when the procedure was performed by the highest volume surgeons compared to when performed by the lowest. No significant effect of surgeon volume on hospital charges, however, was observed. Higher surgeon volume was associated with shorter length of stay but no difference in hospital charges among children undergoing vesicoureteral reimplantation.

The optimal management of malrotation diagnosed after infancy: a decision analysis.

BACKGROUND: The benefit of a prophylactic Ladd's procedure in older children and adults with malrotation is controversial. The purpose of this study was to determine the role of the Ladd's procedure in patients with asymptomatic malrotation diagnosed after infancy. METHODS: A Markov decision analysis was used to compare the quality adjusted life expectancy with and without a Ladd's procedure among patients with asymptomatic malrotation. Data obtained from the Nationwide Inpatient Sample were used to estimate the age-related probability of emergency surgery or volvulus among patients with malrotation. Estimates of the mortality of elective and emergency surgery, mortality of volvulus, and utilities of each health state were obtained from the literature. RESULTS: After infancy, the gain in quality adjusted life expectancy associated with a prophylactic Ladd's procedure was highest when asymptomatic malrotation was treated at 1 year old and steadily declined until asymptomatic malrotation was treated at 20 years old. An increasing advantage of observation over prophylactic surgery on life expectancy was observed after the second decade of life. A 2-fold increase in mortality risk for an elective Ladd's procedure decreased the age threshold to 14 years, whereas a 4-fold increase decreased the threshold to 7 years. These results were found to be robust by sensitivity analyses and Monte Carlo simulation. CONCLUSION: A Ladd's procedure should be considered for children diagnosed with asymptomatic malrotation, particularly those who are younger and with a low risk of postoperative mortality. The rare occurrence of midgut volvulus does not justify performing a prophylactic Ladd's procedure on most adults with malrotation.
