A clinical decision rule for cranial computed tomography in minor pediatric head trauma.

OBJECTIVES: To develop a sensitive clinical decision rule with a high negative predictive value for the use of cranial computed tomography (CT) in minor pediatric head trauma, to identify clinical features predictive of neurosurgical intervention, and to assess clinicians' predictive abilities to determine the presence or absence of intracranial injury based on history and physical examination alone. DESIGN: Prospective observational study. SETTING: Four level I pediatric trauma centers. PARTICIPANTS: One thousand patients younger than 21 years with minor head trauma undergoing cranial CT. MAIN OUTCOME MEASURE: Intracranial injury as demonstrated by CT and neurosurgical intervention. RESULTS: Of 1000 patients in the study, the mean age was 8.9 years, and 64.1% were male; 6.5% (65 of 1000) had positive findings on CT, and 9.2% (6 of 65) of these required neurosurgical intervention. Recursive partitioning identified the following variables in the decision rule: dizziness, skull defect, sensory deficit, mental status change, bicycle-related injury, age younger than 2 years, Glasgow Coma Scale score less than 15, and evidence of a basilar skull fracture. For detection of intracranial injury, the decision rule had a sensitivity of 95.4% (95% confidence interval [CI], 86.2%-98.8%), a specificity of 48.9% (95% CI, 46.6%-52.1%), and a negative predictive value of 99.3% (95% CI, 98.1%-99.8%). CONCLUSIONS: We developed a sensitive clinical decision rule with a high NPV for detection of intracranial injury in minor pediatric head trauma. If validated, this rule could provide a useful adjunct to the physician's clinical assessment by reducing variations in practice and unnecessary cranial CT.

Recognition and management of pediatric fractures by pediatric residents.

BACKGROUND: Competence in basic orthopedic assessment and interpretation of radiographs is important for pediatricians because appropriate initial management of fractures can expedite therapy and minimize morbidity. However, requirements for training in orthopedics and radiology are poorly defined in pediatric residency programs. OBJECTIVE: To assess the ability of pediatric residents to recognize and to manage appropriately pediatric fractures. METHODS: This study involved administration of a case-based questionnaire with radiographs to volunteer categorical pediatric residents in 3 geographically diverse training programs. The diagnosis and management of 8 orthopedic complaints were evaluated. Responses were scored according to the number of features identified accurately, including the presence or absence of a fracture. Residents who were able to identify a fracture were assessed with respect to their ability to classify the fracture and to provide initial management. The study was pretested with a group of pediatric emergency medicine attending physicians, to establish the suitability of the cases. RESULTS: Among the 3 residency sites, 102 of 190 eligible pediatric residents (53.7%) participated, yielding 95 completed questionnaires. The mean number of cases in which a resident correctly answered the question, "Is a fracture present?" and correctly identified the fractured bone (if a fracture was present) was 6.5 +/- 1.2 of 8 cases (81.6%; 95% confidence interval: 78.5-84.7%). The diagnostic accuracy of Salter-Harris classification in cases in which such fractures were present was 40.9%. The mean score of correctly identified features for the resident group was 38.5 +/- 9.4, of a possible 64 points (proportion correct: 60.1%; 95% confidence interval: 57.2-63%). There was a small but significant difference in mean correct responses between first-year residents (proportion correct: 55.4%; 95% confidence interval: 50.8- 60.3%) and third-year residents (proportion correct: 65.1%; 95% confidence interval: 60.7-69.5%). There was no association between the proportion of correct responses and whether or not residents had taken radiology or orthopedics elective courses in medical school. Overall, 43% of cases were both identified and managed correctly by the pediatric residents. CONCLUSIONS: For residents from the participating training programs, skills in recognizing and managing pediatric fractures were suboptimal. Additional review of training requirements is necessary to identify more clearly areas of improvement for current curricula.

Pediatric emergency department assessment of psychological trauma and posttraumatic stress.

OBJECTIVES: This study aimed to describe the kinds of stressors and the extent of symptoms of posttraumatic stress disorder (PTSD) that were reported by children and their parents in a pediatric emergency department and to examine the response rate to an emotional trauma questionnaire in this setting. METHODS: Three self-report questionnaires were given to patients aged eight to 21 years and to their primary caretakers: a brief assessment of service use, the Posttraumatic Stress Reaction Index (PTSRI), and the Impact of Event Scale (IES). RESULTS: Sixty-four of 81 families who were approached agreed to participate (consent rate of 79 percent), and 62 completed the questionnaires. Fifty-six patients reported at least one event that met DSM-IV-TR criteria for emotional trauma. The average number of reported events per child was 3.14 (range, 0 to 7). Eighteen patients met threshold criteria for severity of PTSD symptoms. Twenty-five patients reported that the most distressing traumatic event that they experienced was related to a medical illness. Patients with PTSD reported exposure to more adverse life events than patients without PTSD. IES scores reported by caretakers who identified the same event as their child as the most stressful were as high as those of caretakers who reported a different event as the most stressful. CONCLUSIONS: Exposures to emotionally traumatic events and PTSD symptoms are commonly reported in the pediatric emergency department. Asking children and their parents about their history of emotional trauma when they visit the emergency department is possible and can be well received.

Bilious emesis in the pediatric emergency department: etiology and outcome.

The objective of this study was to describe the emergency department (ED) diagnoses in an unselected pediatric population with bilious emesis. In a multicenter, prospective, observational case series, a convenience sample of patients less than 21 years old with yellow or green emesis were assembled. Clinical review of each case was performed 2 weeks or longer after ED disposition. Two hundred twenty-seven patients with 230 ED encounters were enrolled. Of the 189 encounters (82.2%) with follow-up, 20 had surgical disease (10.6%; 95% C.I. 6.6%, 15.9%). There was no significant association between the color of the emesis and surgical disease (OR = 2.3; 95% CI, 0.68, 8.6).
