Initial experience with a multi-station objective structured teaching skills evaluation.

PURPOSE: To explore the applicability of using an objective structured evaluation to assess community preceptors' teaching performances. METHOD: The authors developed and, in 1996, administered an objective structured teaching evaluation (OSTE) at the University of California, Irvine, College of Medicine. They compared assessments of teaching skills made by faculty observers and standardized students, and examined instrument reliability, realism, and utility. RESULTS: Reliabilities of the OSTE varied with individual stations but, in several instances, approached acceptable standards. Faculty observers' and standardized students' evaluations of preceptors' performances were similar. Participants' feedback indicated that the greatest OSTE-related benefit was derived by the faculty observers. CONCLUSIONS: An OSTE that reflects realistic teaching situations can be successfully developed. Objective structured evaluation can be successfully applied to assessing faculty teaching performance. However, it may be no more discriminating than are student evaluations. An OSTE's utility may be greatest in guiding faculty development initiatives.

Use of an objective structured clinical examination in evaluating student performance.

BACKGROUND AND OBJECTIVES: The objective structured clinical exam (OSCE) is increasingly being used to evaluate student clinical performance. However, scant literature exists pertinent to this approach in evaluating family medicine clerkship performance. In this study, we assess 8 years' experience with a family medicine clerkship OSCE. METHODS: Eight annual clerkship OSCEs and the performance of 696 students are described. Comparisons of faculty evaluation, written exam, and OSCE performance are made for 335 students. Post-OSCE student and faculty feedback regarding OSCE validity and utility is also presented. RESULTS: Student performance is highest in medical history taking and physical examination and lowest in information-sharing stations. OSCE results appear to be relatively consistent on a year-to-year basis. OSCE, faculty evaluation, and written exam results have low overall levels of correlation, particularly in assessing performance that differs substantially from the mean. Students and faculty agree that the OSCE experience reflects skills that students should possess, but there is less agreement that the OSCE reflects clerkship-related learning and actual student performance. Both students and faculty derive insight from the OSCE regarding the definition of specific learning needs. CONCLUSIONS: The family medicine clerkship OSCE we describe appears to provide consistent measures of student performance. Although content validity is high, further assessment is needed to assure construct validity. The OSCE experience provides students with a rich resource for defining clerkship-related learning needs. Study results strongly suggest that OSCEs, faculty evaluations, and written exams provide differing measures of student performance. The reasons for these differences merit further exploration.

[Comparison of 2 treatment schemes to eradicate Helicobacter pylori].

INTRODUCTION: Anti secretory drugs, antimicrobials and bismuth salts are used with variable success to eradicate Helicobacter pylori. AIM: To assess the effectiveness and rates of reinfection of two therapeutic modalities H pylori infection in adult patients with duodenal ulcer or non ulcer dyspepsia. METHODS: During upper gastrointestinal endoscopy, 5 antral and 2 fundic biopsies were obtained and sent for microbiological and anatomopathological study. Patients infected with Helicobacter pylori were randomly assigned to receive during two weeks omeprazole 20 mg od plus amoxicillin 500 mg tid (group A) or bismuth subsalicylate 260 mg bid, metronidazole 250 mg tid and amoxicillin 500 mg tid (group B). A new endoscopy with antral and fundic biopsies was performed to all patients four weeks after discontinuing treatment and six months later to those in whom H pylori was eradicated. RESULTS: Eighty patients (40 in each treatment group) completed the treatment and follow up. H pylori was eradicated in 22 patients of group A (55%) and 28 of group B (70%). Minor adverse effects were reported by 5 patients in group A (12%) and 11 in group B (27.5%). Six months later, reinfection was documented in 12 patients of group A and 8 of group B (54% and 30% of those with successful treatment respectively). Ten of twenty five patients with duodenal ulcer had reinfections, but there was only one ulcer relapse. CONCLUSIONS: These two treatment modalities have similar results.

[Non ulcerative dyspepsia: relationship of symptomatology, gastritis and Helicobacter pylori].

BACKGROUND: histological alterations of gastric mucosa and its colonization by Helicobacter pylori are postuled to be implicated in the pathogenesis of non ulcer dyspepsia. AIM: to study the possible relationships between histological gastritis and Helicobacter pylori in non ulcer dyspepsia symptomatology. PATIENTS AND METHODS: fifty four patients (39 females) with non ulcer dyspepsia whose ages ranged from 17 to 68 years were subjected to an upper GI endoscopy with gastric mucosa biopsy samples for histological study and microbiological identification of Helicobacter pylori. Gastrointestinal complains were blindly quantified using a scored questionnaire. RESULTS: thirty one subjects (57.4%) had Helicobacter pylori in their gastric mucosa. There was acute inflammatory activity in 26 of the 31 patients with Helicobacter pylori (81%) and 15 of 23 without Helicobacter (65%). The median score of symptoms was 7 (range 2-13) in patients with Helicobacter and 6 (range 2-10) in patients without Helicobacter. CONCLUSIONS: there were no significant differences in gastric mucosa acute inflammatory activity and non ulcer dyspepsia symptomatology between patients with or without Helicobacter pylori colonization of gastric mucosa.

[Etiologic diagnosis of pneumonia in HIV-AIDS patients. Usefulness of fibrobronchoscopy].

AIM: to assess the usefulness of fiberoptic bronchoscopy in the etiologic diagnosis of pulmonary infiltrates in patients with AIDS. PATIENTS AND METHODS: in 25 patients with AIDS and pneumonia, 31 fiberoptic bronchoscopies with bronchoalveolar lavage were performed; in 11 occasions, a transbronchial biopsy was also performed. RESULTS: in 24 of the 31 procedures (77%) an etiologic diagnosis was made. There were 7 false negative results; in two of these patients, a repeated examination allowed an etiologic diagnosis. The etiologies of the infiltrates were pyogenic bacteria in 14 cases. Pneumocystis carinii in 9, mycobacteria in 3, cytomegalovirus in one and a lymphocytic interstitial pneumonia in one. In 5 patients, the association of two or more etiological agents was observed. Except one case, all patients had a good response to specific treatments. There were no complications attributed to the bronchoscopic procedure. CONCLUSIONS: fiberoptic bronchoscopy and bronchoalveolar lavage are safe and effective procedures for the etiologic diagnosis of pulmonary infiltrates in patients with AIDS.

[Etiologic diagnosis of pneumonia in adults: usefulness of bronchoalveolar lavage].

Quantitative evaluation of bacteria in bronchoalveolar lavage fluid from 15 patients with pneumonia was compared to that in 29 healthy controls. Aerobic and anaerobic cultures were used as well as cultures and staining for fungi and mycobacteria. A total of 1000 colony forming units per ml was considered a cutoff mark between colonization and infection. A positive result was obtained in 13 of 15 patients with pneumonia, allowing the identification of the causing agent. Counts below the indicated level were observed in 23 of 29 controls. There was no morbidity associated to the procedure. Thus, an 85% sensitivity and 87% specificity for bronchoalveolar lavage in the etiologic diagnosis of pneumonia may be estimated from this study.
