We compared direct hospital costs and indirect costs to the family associated with immediate appendectomy or initial nonoperative management for perforated appendicitis in children.
From June 2009 through May 2010, 61 prospectively identified families completed a cost diary, documenting the numbers of missed school days for the child and missed employment days for the adult caregiver(s) over the treatment course. Hospital costs were obtained from hospital financial databases. Mann-Whitney U tests and Fisher exact tests were used to compare outcome measures for each treatment strategy.
Patients treated by initial nonoperative management had a significantly longer median length of stay (9 days vs 7 days, P = .02) and a significantly greater median total hospital cost per patient ($31,349 vs $21,323, P = .01) when compared with those treated by immediate appendectomy. There was no significant difference in median number of missed school days (9 days vs 10 days, P = .23) or missed employment days for adult caregiver(s) (5 days vs 7 days, P = .18) between treatment strategies.
Patients with perforated appendicitis treated by initial nonoperative management had a greater length of stay and a significantly greater total hospital cost but were not burdened by significantly greater indirect costs compared with those treated by immediate appendectomy.
[Show abstract][Hide abstract] ABSTRACT: This study aimed to determine whether routine urinalysis may serve as a tool in discriminating between acute appendicitis and perforated appendicitis in children.
We prospectively collected 357 patients with clinically suspected acute appendicitis. Urinalysis was performed in patients with clinically suspected acute appendicitis before surgical intervention. Routine urinalysis is composed of 2 examinations: chemical tests for abnormal chemical constituents and microscopic tests for abnormal insoluble constituents. Receiver operating characteristic curves for urine white blood cell (WBC) counts and urine red blood cell (RBC) counts in distinguishing between patients with simple appendicitis and patients with perforated appendicitis were also analyzed.
Urine ketone bodies, leukocyte esterase, specific gravity, pH, WBC, and RBC counts were all significant parameters among patients with normal appendices, simple appendicitis, and perforated appendicitis (all P < .05). Based on multivariate logistic regression analysis, positive urine ketone bodies and nitrate were significant parameters in predicting perforated appendicitis (P = .002 and P = .008, respectively). According to the results of receiver operating characteristic curves, the appropriate cutoff values were 2.0/high-power field for urine RBC counts and 4.0/high-power field for urine WBC counts in predicting perforated appendicitis in children.
Routine urinalysis may serve to aid in discriminating between simple and perforated appendicitis. Clinically, we believe that these urine parameters may aid primary emergency physicians with decision making in patients with clinically suspected appendicitis.

[Show abstract][Hide abstract] ABSTRACT: Background:
In 2006, an evidence-based protocol for the management of children with appendicitis was established at our institution. Discharge criteria for patients with advanced appendicitis were based on a combination of clinical parameters and laboratory values. The purpose of this study is to evaluate the utility of laboratory values in guiding patient management with a discharge protocol for advanced appendicitis.
Materials and methods:
We reviewed charts of patients with advanced appendicitis as defined by the surgeon intraoperatively from 2008-2009. We evaluated the sensitivity and specificity of the laboratory values at discharge for predicting postoperative intra-abdominal abscess (IAA) formation using a receiver operator curve. A logistic regression analysis was performed to identify predictors of IAA formation.
We identified 450 patients (mean age 8.9 ± 3.9 y). The postoperative IAA rate was 25%. The sensitivity and specificity for developing an abscess with a white blood cell count >12,000/UL were 52% and 82%, respectively (AUC 0.72, 95% CI 0.67-0.78, P < 0.001). The sensitivity and specificity for bands >3% were 47% and 70% (AUC 0.60, 95% CI 0.53-0.67, P = 0.002), respectively. On logistic regression analysis, an elevated white blood cell count was independently associated with an increased likelihood of a postoperative IAA (OR 1.27, 95% CI 1.19-1.35, P < 0.001).
The absence of leukocytosis is useful for identifying children with a decreased risk of postappendectomy IAA formation who otherwise meet clinical discharge parameters. A band count is not as predictive of risk. The use of laboratory evaluation as a component of discharge criteria in advanced appendicitis can stratify a subset of patients who are at increased IAA risk and may benefit from continued antibiotic therapy.

[Show abstract][Hide abstract] ABSTRACT: Background:
A diagnostic algorithm for appendicitis in children was created to reduce computed tomography (CT) use owing to the risk of cancer from radiation exposure and cost of CT. This study evaluates the impact of the algorithm on CT use and diagnostic accuracy of appendicitis.
Patients ≤18 years who underwent appendectomy for suspected appendicitis after presenting to the emergency department for 2 years before and 3 years after algorithm implementation were identified. Clinical characteristics and outcomes, including use of CT and negative appendectomy rate, were compared between the pre- and post-implementation periods. Multivariable analysis was used to determine the impact of CT on negative appendectomy.
We identified 331 patients-41% in the pre- and 59% in the post-implementation period. CT utilization decreased from 39% to 18% (P < .001) after implementation. The negative appendectomy rate increased from 9% to 11% (P = .59). Use of CT did not impact the risk of negative appendectomy (P = .64).
Utilization of CT was significantly reduced after implementation of a diagnostic algorithm for appendicitis without impacting diagnostic accuracy. Given the concern for increased risk of cancer after CT, these results support use of an algorithm in children with suspected appendicitis.
