A Training Program Using an Audience Response System to Calibrate Dental Faculty Members Assessing Student Clinical Competence.

The aim of this study was to assess the effectiveness of calibration training of departmental faculty and competency graders using an audience response system on operative dentistry concepts across 12 months. The training sessions were designed to further solidify the process and equilibration of clinical opinions among faculty members and provide a more calibrated grading assessment during patient care for student performance feedback. Four (quarterly) calibration sessions occurred over 12 months in 2015. The first session was considered the baseline (control value) for this study. Pre- and post-calibration interrater agreement was assessed. Additionally, a pre and post assessment with ten Likert-scale questions was used to measure students' perceptions of instructional consistency. The results showed that a statistically significant increase in conceptual knowledge scores occurred for both departmental faculty members and competency graders across each of the four sessions (one-factor ANOVA; p<0.05). Interrater reliability agreement also significantly improved for both department faculty members and competency graders' clinical assessments over 12 months of implementation (Cohen's Kappa; p<0.05). There was a statistically significant increase in positive student perceptions on all ten questions (dependent t-test; p<0.05). Implementation of an audience response system for departmental and competency graders was found to be effective in facilitating a discussion forum, calibrating clinical assessments, and improving student perceptions. The positive results from this study support the value of dental schools' introducing faculty development programs to ensure consistent instruction for assessing dental student competence.

Evaluation of intracranial meningioma resection with a surgical aspirator in dogs: 17 cases (1996-2004).

OBJECTIVE: To determine results of intracranial meningioma resection by use of a surgical aspirator and assess prognostic factors associated with intracranial meningiomas in dogs. DESIGN: Retrospective case series. ANIMALS: 17 dogs. PROCEDURES: Medical records of dogs that underwent resection of an intracranial meningioma by use of a surgical aspirator were reviewed. Information pertaining to signalment, imaging findings, clinical signs, duration of clinical signs, preoperative treatment, location of the tumor, results of histologic assessment, outcome, and necropsy results was obtained from the medical record. Clients and referring veterinarians were contacted via telephone for information on recurrence of clinical signs and postoperative survival time. RESULTS: 16 dogs were > 7 years of age, and all 17 dogs had seizures before surgery. The most commonly affected breed was the Golden Retriever, represented by 6 of the 17 dogs. Median survival time was 1,254 days. Of the data collected, only histologic subtype of the tumor was prognostic. Analysis of survival times according to histologic tumor subtypes indicated that the order from most brief to longest was as follows: anaplastic, 0 days; fibroblastic, 10 days; psammomatous, > 313 days; meningothelial, > 523 days; and transitional, 1,254 days. CONCLUSIONS AND CLINICAL RELEVANCE: Use of a surgical aspirator to resect intracranial meningiomas in dogs was associated with longer survival times than those achieved with traditional surgery alone or traditional surgery combined with radiation therapy. Dogs with meningothelial, psammomatous, or transitional intracranial meningioma subtypes appeared to have a better prognosis than dogs with other subtypes of meningioma.
