A drop in pediatric subject examination scores after curriculum changes that emphasize general pediatric topics.

OBJECTIVE: To determine whether emphasizing a limited number of general pediatric objectives and using a test based on them would improve student knowledge of the topic areas. DESIGN: Before-after trial. SETTING: Community-based medical school. SUBJECTS: Third-year medical students on a required clerkship in pediatrics. INTERVENTION: Six core objectives: recognizing the seriously ill child, stabilizing such a child, fluid and electrolyte requirements and therapy, newborn care, well child care, and variability of normal vital signs in children based on their age were defined and a modified essay examination was constructed. The test was given to pediatric students close to the end of their clerkship. In study year 1, no warning was given about the examination and results did not affect student grades. In study year 2, passing all items was a requirement and failure required remedial oral examination of any missed items. All students completed the National Board of Medical Examiners pediatric subject examination. RESULTS: For 7 of 8 essay items, significant increases in numbers of students passing were seen in study year 2, but students scored 51 points lower on the National Board of Medical Examiners pediatric subject examination (P=.002). The decrease in scores was not seen in any other clerkship or among pediatric students from a different campus of the medical school. CONCLUSIONS: Emphasis on core objectives and an essay examination significantly improved students' knowledge of the defined topics but decreased the scores on the National Board of Medical Examiners subject examination. This may be attributable to a difference in content between the 2 tests. Faculty proposing new curriculum guidelines need to review student assessment methods to avoid such unexpected changes in scores.

Deficiencies in calculation and applied mathematics skills in pediatrics among primary care interns.

OBJECTIVE: To discover how well new house officers in primary care residency programs perform the mathematical calculations necessary to function effectively in pediatric and nursery settings. DESIGN: Criterion-referenced survey examination testing unit conversion, fluid and rehydration management, and drug-dosing skills. SETTING: Five primary care residences in family practice and pediatrics at urban and community campus sites in Illinois. PARTICIPANTS: Twenty-three family practice residents and 11 pediatric residents tested during residency orientations sessions or in conferences during the first 3 months of training. INTERVENTIONS: None. RESULTS: The mean score for all residents was 42%. Pediatric residents (mean score, 57.8%) performed significantly better than family medicine residents (mean score, 34.4%) (P = .002). Conversion from conventional to metric units was more difficult for family practice residents, but pediatric residents also made errors. Pediatric residents were significantly better than family medicine residents at calculation of fluid maintenance requirements (P < .05). Only 5 of 34 residents wrote acceptable fluid orders. Nutritional and drug therapy calculations showed fewer mathematical errors, but neither group routinely wrote medical orders that specified the drugs or formula, concentration, volume required per dose or feeding, route of administration, dosing interval, and duration of therapy. CONCLUSIONS: The potential for serious clinical errors caused by faculty calculation of dosage by house staff officers is high. New residents should have their orders for fluids and drugs double-checked by senior personnel early in their training. Residency programs should provide remedial skills training for house officers with deficiencies in applied mathematics. The medical school faculty needs to assess students' competence in mathematics before allowing independent clinical responsibility.

Computed tomographic findings in akinetic mutism.

Brain-injured children who progress from coma to a sleeplike state of akinetic mutism are often misinterpreted by their parents as having improved. In children with akinetic mutism caused by extensive destruction of the cerebral gray matter, the computed tomographic scan may demonstrate the irreversible nature of the pathologic changes.
