Perceptions of clinical teachers acting as examiners regarding the value of Objective Structured Clinical Examinations.

OBJECTIVES: OSCE (Objective Structured Clinical Examination) is a common method of assessing clinical skills used at many universities. An important and at the same time difficult aspect of good examination preparation is obtaining a properly trained and well-motivated group of assessors. To effectively recruit and maintain cooperation with assessors, it is worth to know their opinion. The aim of this study was to investigate the opinions of teacher-examiners about OSCE and to identify the factors that could shape this opinion and influence on motivation. METHODS: A cross-sectional study was conducted using a questionnaire on teachers who participated as OSCE examiners. This questionnaire consisted of 21 questions about their perceptions. Answers were rated in a five-point Likert-type scale. Chi-square or Fisher's exact test was used to analyze the data. RESULTS: A total of 49 (out of 52) teachers participated in this study. Nearly 90% of examiners believed that it is fair, more than 90% that it is transparent. Despite the fact that 67% of examiners believe the examination is difficult to organize and 71% believe it is stressful for students, according to 72% of respondents the OSCE has a positive effect on learning. More than 91% of examiners believed that the OSCE is an appropriate test to assess students' skills. Opinions about examination were independent of specialty, seniority, gender or taking the OSCE as students. CONCLUSION: Teacher-examiners viewed the OSCE as a fair and transparent examination, adequate for assessment of skills and, despite it being difficult to organize, worth doing as it is appropriate to assess practical skills and positively influences students' motivation to learn tested skills.

The Objective Structured Clinical Examination (OSCE) from the perspective of 3rd year's medical students - a pilot study.

BACKGROUND: In 2015 Department of Medical Education in Medical College of Jagiellonian University in Cracow performed a new format of integrated multidisciplinary skills assessment of third year students of medicine a er completing initial courses in internal medicine, surgery, pediatrics and gynecology. AIM: OSCE assessed from the perspective of 3rd year medical students. METHODS: Students of 3rd year's study of Faculty of medicine were evaluated by OSCE, which assessed their internal medicine, surgery, gynecology, pediatric skills. OSCE consisted of 12 stations. In order to assess student's opinions on OSCE, we used method of diagnostic survey; Statistica 12.0. RESULTS: OSCE passed 255 (98.83%) of the students in thefirst term. We analyzed 221 questionnaires, in which students expressed their opinion. 93.7% of the students considered OSCE as a well organized exam. 87.8% of students claimed that OSCE is fair and 95.5% that the exam is clear. 86.4% students are pleased with the introduction information about OSCE that was given before the examination. 78.6% students believe, that OSCE allows to properly identify skills that require improvement. Students, who didn't pass all stations with positive result, more o en (Chi^2 Pearsona, p = 0.01990) indicated improper balance between quantity of stations that check communication skills and these checking other clinical skills. CONCLUSIONS: is study confirms that OSCE in the students' opinions was well organized and fair. It proves that OSCE correctly selects students who need to improve their knowledge and skills. Students' preparing to the exams, their knowledge and skills, influences on the students' perception of OSCE.

Primary mediastinal B-cell lymphoma - metabolic and anatomical features in 18FDG-PET/CT and response to therapy.

AIM OF THE STUDY: Determining the role of PET/CT imaging in the evaluation of treatment efficacy in primary mediastinal B-cell lymphoma (PMBCL). MATERIAL AND METHODS: Retrospective analysis of seven PMBCL patients, treated at the University Hospital in Krakow, with interim PET/CT after the third course of chemo-immunotherapy.The analysis was based on the calculation of exact tumour volume and metabolic activity, compared with initial values (directly after diagnosis). RESULTS: Patients (five females, two males, average age 26.2 years, range 18-40 years), in clinical stage IIBX at diagnosis, were treated with eight cycles of R-CHOP-14 regimen, with radiotherapy consolidation (7/7) and central nervous system prophylaxis (6/7). The observed decrease in tumour volume between the initial staging and the interim PET ranged 72-89%. The mean ΔSUVmax reduction between initial (when available) and interim PET was 87% (range 84-89%). In 3/7 cases in the interim PET/CT, the uptake of the tumour was higher than the liver (Deauville Criteria score 4-5), and in 4/7 it was lower than the liver but higher than mediastinal blood pool structures (score 3 according to Deauville Criteria). After a median follow-up of 58 months - OS and EFS is 100%. CONCLUSIONS: The excellent clinical outcome in the study group corresponds with very good metabolic and volumetric response in the interim PET. The ΔSUVmax seems to be easier in implementation and has a more significant impact than other measurements.

Early chemotherapy de-escalation strategy in patients with advanced-stage Hodgkin lymphoma with negative positron emission tomography scan after 2 escalated BEACOPP cycles.

INTRODUCTION Escalated BEACOPP (escBEACOPP: bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone) significantly improves overall response rates (ORRs) and prolongs progression­free survival (PFS) in patients with advanced­stage Hodgkin lymphoma (HL). However, 6 to 8 cycles of escBEACOPP are associated with increased acute toxicity and late complications. OBJECTIVES We aimed to determine the role of early positron emission tomography-computed tomography (PET­CT) response assessment in a de­escalation strategy. PATIENTS AND METHODS We retrospectively analyzed 188 consecutive patients with advanced­stage HL treated at diagnosis. Patients received 2 cycles of escBEACOPP followed by an early PET­CT response assessment performed after 2 cycles of chemotherapy (PET2). Patients with an active disease continued therapy with escBEACOPP, while those with negative PET2 were de­escalated to ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine). Radiotherapy was allowed in patients with stage IIBX. RESULTS PET2 allowed for de­escalation of therapy in 141 patients (75%). Their ORR was 92.2%, with a complete remission (CR) rate of 91.5%; 10­year PFS and overall survival (OS) were 87.2% and 95%, respectively. In the whole cohort, ORR was 87.8% (CR, 85.6%), while the 10­year PFS and OS were 79.3% and 89.4%, respectively. Hematological and thromboembolic complications were significantly more frequent in patients treated with 6 escBEACOPP cycles, including febrile neutropenia (25 patients, [53.2%] vs 7 [5%]), serious anemia (35 [74.5%] vs 11 [7.8%]), or thrombocytopenia (16 [34%] vs 7 [5%]) (P <0.001 for all comparisons with de­escalation strategy) as well as pulmonary embolism (3 [6.4%] vs 0) (P = 0.02). CONCLUSIONS The early de­escalation strategy allows for effective treatment of advanced HL, with a comparable efficacy to that of 6 to 8 cycles of escBEACOPP, but with significantly reduced toxicity.
