Evaluation of an evidence-based guideline to reduce CT use in the assessment of blunt pediatric abdominal trauma.

PURPOSE: About half of pediatric blunt trauma patients undergo an abdominopelvic computed tomographic (CT) scan, while few of these require intervention for an intraabdominal injury. We evaluated the effectiveness of an evidence-based guideline for blunt abdominal trauma at a Level I pediatric trauma center. METHODS: Pediatric blunt trauma patients (n = 998) age 0-15 years who presented from the injury scene were evaluated over a 10 year period. After five years, we implemented our guideline in which the decision for CT was standardized based on mental status, abdominal examination, and laboratory results (alanine aminotransferase, aspartate aminotransferase, hemoglobin, urinalysis). RESULTS: There were no differences in age, GCS, SIPA or ISS scores between the patients before or after guideline implementation. Nearly half of the patients (48.3%) underwent CT scan before guideline implementation compared to 36.7% after (p < 0.0002). There was no difference in ISS (p = 0.44) between CT scanned patients in either group. No statistical differences were found in rate of intervention (p = 0.20), length of stay (p = 0.65), or readmission rate (0.2%) before versus after guideline implementation. There were no missed injuries. CONCLUSION: Implementation of an evidence-based clinical guideline for pediatric patients with blunt abdominal trauma decreases the rate of CT utilization while accurately identifying significant injuries. LEVEL OF EVIDENCE: III.

Comparing the cost and outcomes of laparoscopic versus open appendectomy for perforated appendicitis in children.

Although laparoscopic appendectomy (LA) is accepted treatment for perforated appendicitis (PA) in children, concerns remain whether it has equivalent outcomes with open appendectomy (OA) and increased cost. A retrospective review was conducted of patients younger than age 17 years treated for PA over a 12.5-year period at a tertiary medical center. Patient characteristics, preoperative indices, and postoperative outcomes were analyzed for patients undergoing LA and OA. Of 289 patients meeting inclusion criteria, 86 had LA (29.8%) and 203 OA (70.2%), the two groups having equivalent patient demographics and preoperative indices. Inpatient costs were not significantly different between LA and OA. LA had a lower rate of wound infection (1.2 vs. 8.9%, P = 0.017), total parenteral nutrition use (23.3 vs. 50.7%, P < 0.0001), and length of stay (5.56 ± 2.38 days vs. 7.25 ± 3.77 days, P = 0.0001). There was no significant difference in the rate of postoperative organ space abscess, surgical re-exploration, or rehospitalization. In children with PA, LA had fewer surgical site infections and shorter lengths of hospital stay compared with OA without an increase in inpatient costs.

Delays in treatment of pediatric appendicitis: a more accurate variable for measuring pediatric healthcare inequalities?

Racial and socioeconomic factors may cause barriers to healthcare access that result in delayed treatment. Because perforated appendicitis (PA) in children is thought to result from delays in treatment, it is often used as an index of barrier to access. Recent literature suggests that PA is not an inevitable consequence of delayed treatment, so it may not be the best marker for evaluating such barriers. Therefore we investigated whether racial and socioeconomic factors led directly to delays in treatment. We performed a retrospective study of 667 children undergoing appendectomy in a tertiary care center over 12.5 years. Univariate and multivariable regression analyses were used to determine if racial and socioeconomic variables were associated with increased risk of PA and increased risk of symptom duration greater than 48 hours. Hispanic children have higher rates of PA regardless of delays in treatment whereas black children had higher PA rates likely due to delays in treatment. These differences were not from socioeconomic factors in our cohort. PA, a heterogeneous disease whose course is determined by multiple factors, is not a good metric for evaluation healthcare disparities in the pediatric population. Delays in treatment may be a more appropriate measure of healthcare inequalities in children.

Disk battery ingestion: case series with assessment of clinical and financial impact of a preventable disease.

BACKGROUND: Commonly, foreign objects are incidentally ingested and pass harmlessly through the gastrointestinal tract; however, disk batteries present exceptional risk. In 2009, the American Association of Poison Control Centers listed disk batteries as the number 1 cause of fatal ingestions in children younger than 5 years. Lithium batteries are the most dangerous, and they are rapidly rising in use by manufacturers. Paralleling that rise, there has been a 6.7-fold increase in major or fatal outcomes between 1985 and 2009. This study describes the variability in patient presentations, the courses of patients' evaluations, and the clinical and financial consequences of disk battery ingestion. METHODS: In this retrospective study, cases from 2001 to 2011 were reviewed for details of care for disk battery ingestions including presentation and management details. Cost of care information from our patients' records was compared with that of national averages on esophageal foreign bodies using the Healthcare Cost and Utilization Project's Kids' Inpatient Database. RESULTS: Six cases are presented. The patients' age averaged 1.85 years. Presentations varied with respect to symptoms, time course, and steps in treatment. Mean length of stay was 9.0 days, and mean cost was $14,994. CONCLUSIONS: Emergency medicine physicians, otolaryngologists, radiologists, gastroenterologists, and pediatric surgeons may be able to mitigate, albeit not entirely prevent, potential serious complications in patients with disk battery ingestions by proper diagnosis and timely treatment. Recommendations for management are presented, which highlight the need for emergent removal of any battery that is lodged and close follow-up of these patients once they are out of the hospital.

Differences in outcome with subspecialty care: pyloromyotomy in North Carolina.

BACKGROUND/PURPOSE: Proponents of subspecialization in surgery claim that fellowship training improves the quality of care. Others claim that general training is adequate for most routine surgical procedures. The authors questioned whether there were differences in outcomes when general surgeons (GEN) operate on children and infants with common surgical conditions compared with the care of their pediatric surgical (PED) colleagues. METHODS: The authors retrospectively reviewed the Healthcare Investment Analysts North Carolina Information Network database to identify patients who underwent pyloromyotomy for congenital hypertrophic pyloric stenosis in North Carolina during the period from October 1995 through September 1998 (n = 780). Information obtained included demographics, insurance type, hospital, length of stay, total hospital charges, occurrence of mucosal perforation, and type of surgeon (general v pediatric). RESULTS: Of the 780 pyloromyotomies performed, 363 (48%) were performed by pediatric surgeons. Pediatric surgeons cared for more Medicaid patients than general surgeons (PED, 52% v GEN, 40%; P =.001). Infants treated by pediatric surgeons had a lower incidence of mucosal perforation (PED, 0.5% v GEN, 2.9%; P =.0015), which was associated with decreased overall total hospital charges (no perforation, $4,806 plus minus 79 v perforation, $6,592 plus minus 492; P =.002). When patients with uncomplicated pyloric stenosis were evaluated (96% of cases), those cared for by pediatric surgeons had lower total hospital charges (PED, $4,496 plus minus 95 v GEN, $5,121 plus minus 121; P =.0001) and shorter length of stay (PED, 2.7 plus minus 0.1 days v GEN, 3.1 plus minus 0.1 days; P =.01). CONCLUSIONS: In North Carolina, general surgeons treat more than half the patients who have pyloric stenosis, though fewer with Medicaid. The cost and incidence of mucosal perforation were increased in infants with pyloric stenosis when care was provided by general rather than pediatric surgeons.
