1 Case-method as a form of control of education quality in internship at specialization Clinical Laboratory Diagnostic Ass. Prof. O. Lebedeva

2 Stage of education at CLD course Pre-diploma level General and clinical disciplines Post-graduate Primary Primary Periodical Periodical

3 Aim of education

4 Forms of education 61,5% - classic education 32,3% - innovative forms 6,2% - self-education

5 Types of education control ВходнойТекущийРубежныйИтоговый

6 Over 75% study hour in internship are given to practice

7 Case-method Interactive technology for brief education based on real of imagined situations (from English «case» ), aimed at formation of new skills at young doctors

8 Types of use of Cases Case-discussion Case-discussion (open discussion) Case-exam Case-exam (with or without (with or without preparation) preparation)

9 Goal to use case-method Fixation of knowledge from lectures course Fixation of knowledge from lectures course Fixation of practical skills after seminars and practices Fixation of practical skills after seminars and practices Fixation of skills of group work and decision-making Fixation of skills of group work and decision-making

10 Sequence of actions at situational education Distribution of group into subgroups Distribution of group into subgroups Choosing the leader of a group Choosing the leader of a group Study of case with using lecture material Study of case with using lecture material Types of work: Every subgroup works out its own definite situation Every subgroup works out its own definite situation All subgroups work out the one and the same situation, competing with each other All subgroups work out the one and the same situation, competing with each other Group discussion Group discussion Summing up and writing of results Summing up and writing of results

11 Study case reflects typical situations which are often in real life and which a specialist will meet during his professional activity

12 Case-exam Students are given cases directly at exam. They must analyze the case and report to the teacher answering all questions. Students are given cases directly at exam. They must analyze the case and report to the teacher answering all questions. Exam case should be short and simple enough to be processed within time-limit. Exam case should be short and simple enough to be processed within time-limit.

13 Aim of case-method in the end of education program Expertise of knowledge that students got during theoretical course and skills that students got during seminars and practice Expertise of knowledge that students got during theoretical course and skills that students got during seminars and practice

14 Stages of qualification exam Test control Test control Evaluation of practical skills Evaluation of practical skills Oral inter-disciplinary exam Oral inter-disciplinary exam

15 Level of competence Practical possession of research method Practical possession of research method Interpretation of laboratory tests Interpretation of laboratory tests Conclusion (laboratory diagnosis) Conclusion (laboratory diagnosis)

16 Evaluation of results Evaluation of case solution is made on criteria using 100 points system Evaluation of case solution is made on criteria using 100 points system Results of practical skills are evaluated as «pass» or «not pass» Results of practical skills are evaluated as «pass» or «not pass» To get «pass» one should have 75 amd more points To get «pass» one should have 75 amd more points

17 Criteria of case evaluation Correctness of interpretation of comparative analysis of laboratory data and referral indicators Correctness of interpretation of comparative analysis of laboratory data and referral indicators Possession of special terminology and quality of drug description Possession of special terminology and quality of drug description Correctness of evaluation of morphological characteristics of a drug on microphoto Correctness of evaluation of morphological characteristics of a drug on microphoto Comparison of results with laboratory diagnosis Comparison of results with laboratory diagnosis Every criterion has maximum of 25 points Every criterion has maximum of 25 points

18 Case portfolio in CLD Over 140 cases are developed and used Quality control of laboratory tests Quality control of laboratory tests Evaluation of anemia using results of periphery blood test Evaluation of anemia using results of periphery blood test Evaluation of Morphological characteristics of cells in laboratory diagnostic of hemoblastosis Evaluation of Morphological characteristics of cells in laboratory diagnostic of hemoblastosis Evaluation of microscope investigation (sputum, urine, fecal) Evaluation of microscope investigation (sputum, urine, fecal) Evaluation of microscope investigation of vagina preparates and ejaculate Evaluation of microscope investigation of vagina preparates and ejaculate Evaluation of samples for honoccoccus Evaluation of samples for honoccoccus Laboratory diagnostic of malaria Laboratory diagnostic of malaria To be developed: Cytological tests Cytological tests Medical genetic tests Medical genetic tests
