Back Pain in a Pediatric Emergency Department: Etiology and Evaluation.

OBJECTIVES: Back pain is an uncommon chief complaint in the pediatric emergency department (ED). However, there are serious underlying conditions requiring prompt diagnosis and treatment. While the etiology is usually benign, variation exists in the evaluation. The study purpose was to describe pediatric patients who presented to the ED with back pain and evaluate for associations with laboratory and radiologic abnormalities indicative of underlying musculoskeletal pathology. METHODS: A retrospective review was conducted of patients aged birth to 18 years who presented to a pediatric ED with a chief complaint of back pain during a 1-year period. Primary outcome was discharge diagnosis, categorized as nonpathologic back pain, pathologic back pain, and other etiologies. Descriptive statistics were used. RESULTS: Two-hundred thirty-two patient encounters were reviewed, with 177 included in data analysis. A nonpathologic diagnosis of back pain was found in 76.8% of visits. Back pain and back or muscle strain were the most common diagnoses. Pathologic back pain diagnoses represented 2.3% of visits. Radiologic imaging was performed in 37.9%. Positive findings were noted in 16.9% of radiographs; no abnormalities were noted on computed tomography scan or magnetic resonance imaging. Laboratory studies were conducted in 35%. Abnormal plain radiographs were associated with a pathologic diagnosis of back pain (P < 0.001). CONCLUSIONS: Most pediatric patients presenting to the ED with back pain were found to have a nonpathologic etiology and were discharged. Among those with a pathologic back pain diagnosis, abnormal radiograph findings were the only statistically significant factor, whereas laboratory studies, computed tomography scans, and magnetic resonance imaging scans were less indicative.

Symptom-Guided Emergency Department Discharge Instructions for Children With Concussion.

OBJECTIVES: The objective was to evaluate the use and utility of a novel set of emergency department discharge instructions (DIs) for concussion based on a child's ongoing symptoms: symptom-guided DIs (symptom DIs). Differences in clinical outcomes were also assessed. METHODS: A convenience sample of 114 children aged 7 to 17 years presenting to an urban pediatric emergency department with a complaint of concussion was assembled. Children were randomized to standard DIs or symptom DIs. Children completed a graded symptom checklist (GSC) and completed daily the GSC for 1 week. Telephone follow-up was performed at 7 days after enrollment using a standardized survey. RESULTS: Fifty-eight children received the symptom DIs, and 56 received the standard DIs. Rates of use were similar with reported rates of 92% for symptom DIs and 84% for standard DIs. Caregivers with symptom DIs reported that the DIs were more helpful in determining when their child could return to school and physical activity (P < 0.05) than caregivers with standard DIs. Children continued to have postconcussive symptoms days and weeks after their injury with 44% of children with symptom DIs and 51% of children with standard DIs reporting symptoms on the GSC at 1 week. CONCLUSIONS: Both study groups reported frequent use of the DIs. Caregivers with symptom DIs found them particularly helpful in determining when their child could return to school and physical activity. Larger-scale investigations are needed to further develop instructions that are easy to use and that may decrease the postconcussive period.

Abdominal CT Does Not Improve Outcome for Children with Suspected Acute Appendicitis.

INTRODUCTION: Acute appendicitis in children is a clinical diagnosis, which often requires preoperative confirmation with either ultrasound (US) or computed tomography (CT) studies. CTs expose children to radiation, which may increase the lifetime risk of developing malignancy. US in the pediatric population with appropriate clinical follow up and serial exam may be an effective diagnostic modality for many children without incurring the risk of radiation. The objective of the study was to compare the rate of appendiceal rupture and negative appendectomies between children with and without abdominal CTs; and to evaluate the same outcomes for children with and without USs to determine if there were any associations between imaging modalities and outcomes. METHODS: We conducted a retrospective chart review including emergency department (ED) and inpatient records from 1/1/2009-2/31/2010 and included patients with suspected acute appendicitis. RESULTS: 1,493 children, aged less than one year to 20 years, were identified in the ED with suspected appendicitis. These patients presented with abdominal pain who had either a surgical consult or an abdominal imaging study to evaluate for appendicitis, or were transferred from an outside hospital or primary care physician office with the stated suspicion of acute appendicitis. Of these patients, 739 were sent home following evaluation in the ED and did not return within the subsequent two weeks and were therefore presumed not to have appendicitis. A total of 754 were admitted and form the study population, of which 20% received a CT, 53% US, and 8% received both. Of these 57%, 95% CI [53.5,60.5] had pathology-proven appendicitis. Appendicitis rates were similar for children with a CT (57%, 95% CI [49.6,64.4]) compared to those without (57%, 95% CI [52.9,61.0]). Children with perforation were similar between those with a CT (18%, 95% CI [12.3,23.7]) and those without (13%, 95% CI [10.3,15.7]). The proportion of children with a negative appendectomy was similar in both groups: CT (7%, 95% CI [2.1,11.9]), US (8%, 95% CI [4.7,11.3]) and neither (12%, 95% CI [5.9,18.1]). CONCLUSION: In this uncontrolled study, the accuracy of preoperative diagnosis of appendicitis and the incidence of pathology-proven perforation appendix were similar for children with suspected acute appendicitis whether they had CT, US or neither imaging, in conjunction with surgical consult. The imaging modality of CT was not associated with better outcomes for children presenting to the ED with suspected appendicitis.
