Pediatric clerkship experience and performance in the Nebraska Education Consortium: a community vs university comparison.

OBJECTIVE: To compare the reported experiences and performance on end-of-course examinations of students completing their pediatric clerkship at the University of Nebraska Medical Center (UNMC), Omaha, with that of students completing their clerkship in a community pediatrician's practice (CPP) outside the Omaha metropolitan area. DESIGN: Cohort study. SETTING: Private and/or institutional practices with both ambulatory and hospital components. PARTICIPANTS: For the academic year 1996-1997, all 113 students completing the 8-week third-year pediatric clerkship returned a questionnaire detailing their opinions of the experience. They also completed written (multiple-choice and essay questions) and oral (standardized parent interview) examinations, locally prepared and based on clerkship curriculum objectives provided to the students at orientation. Prior to student placement in the CPP, the clerkship goals, content, and evaluation methods as well as techniques for teaching in a busy office practice were reviewed with the CPP physicians. Eighty-one students performed their clerkship at UNMC while 31 spent all but the first week of the clerkship in the CPP. MAIN OUTCOME MEASURES: The students' opinions about their experiences and their performances on the end-of-course examinations were compared. Statistical analysis of the questionnaire was done using the Fisher exact test and the Mantel-Haenszel chi2 test while examination performance was compared using the t test and the Wilcoxon rank sum test. RESULTS: The UNMC and CPP groups reported similar opinions of their experiences in the newborn nursery and the inpatient portion of the clerkship, but the CPP students were much more positive about their learning experience in the clinic (P=.001). The CPP students reported more involvement in the patient's overall care (P<.001) and in other aspects of clinic operation (P<.001). The UNMC and CPP students had similar opinions of curriculum content, reading material, and didactic instruction. No group differences were found regarding interest in pediatrics as a career. Most importantly, no group differences were found in performance on any portion of the end-of-course examinations. CONCLUSIONS: Community-based education at the third-year clerkship level can be accomplished without a significant effect on student examination performance if students and faculty are aware of and adhere to a common set of goals. The end result is a much more robust experience for students who spend the clerkship in the practice of a community-based pediatrician.

Outcomes after simultaneous pancreas and kidney transplantation and the discriminative ability of the C-peptide measurement pretransplant among type 1 and type 2 diabetes mellitus.

BACKGROUND: Earlier studies reporting outcomes after pancreas transplantation have included a combination of C-peptide cutoffs and clinical criteria to classify type 2 diabetes mellitus (T2DM). However, because the kidney is the major site for C-peptide catabolism, C-peptide is unreliable to discriminate the type of diabetes in patients with kidney disease. METHODS: To improve the discriminative power and better classify the type of diabetes, we used a composite definition to identify T2DM: presence of C-peptide, negative glutamic acid decarboxylase antibody, absence of diabetic ketoacidosis, and use of oral hypoglycemics. Additionally among T2DM patients with end-stage renal disease (ESRD), body mass index of <30 kg/m(2) and use of <1 u/kg of insulin per day were selection criteria for suitablity for simultaneous pancreas and kidney transplantation (SPKT). We compared graft and patient survival between T1DM and T2DM after SPKT. RESULTS: Our study cohort consisted of 80 patients, 10 of whom were assigned as T2DM based on our study criteria. Approximately 15% of patients with T1DM had detectable C-peptide. Cox regression survival analyses found no significant differences in allograft (pancreas and kidney) or patient survival between the 2 groups. The mean creatinine clearance at 1 year estimated by the modification of Diet in Renal Disease (MDRD) equation was not significantly different between the 2 groups. Among those with 1 year of follow-up, all patients with T2DM had glycosylate hemoglobin of <6.0 at 1 year versus 92% of those with T1DM. CONCLUSION: SPKT should be considered in the therapeutic armamentarium for renal replacement in selected patients with T2DM and ESRD. Use of C-peptide measurements for ESRD patients can be misleading as the sole criterion to determine the type of diabetes.
