Objective structured clinical examination "Death Certificate" station - Computer-based versus conventional exam format.

One option for improving the quality of medical post mortem examinations is through intensified training of medical students, especially in countries where such a requirement exists regardless of the area of specialisation. For this reason, new teaching and learning methods on this topic have recently been introduced. These new approaches include e-learning modules or SkillsLab stations; one way to objectify the resultant learning outcomes is by means of the OSCE process. However, despite offering several advantages, this examination format also requires considerable resources, in particular in regards to medical examiners. For this reason, many clinical disciplines have already implemented computer-based OSCE examination formats. This study investigates whether the conventional exam format for the OSCE forensic "Death Certificate" station could be replaced with a computer-based approach in future. For this study, 123 students completed the OSCE "Death Certificate" station, using both a computer-based and conventional format, half starting with the Computer the other starting with the conventional approach in their OSCE rotation. Assignment of examination cases was random. The examination results for the two stations were compared and both overall results and the individual items of the exam checklist were analysed by means of inferential statistics. Following statistical analysis of examination cases of varying difficulty levels and correction of the repeated measures effect, the results of both examination formats appear to be comparable. Thus, in the descriptive item analysis, while there were some significant differences between the computer-based and conventional OSCE stations, these differences were not reflected in the overall results after a correction factor was applied (e.g. point deductions for assistance from the medical examiner was possible only at the conventional station). Thus, we demonstrate that the computer-based OSCE "Death Certificate" station is a cost-efficient and standardised format for examination that yields results comparable to those from a conventional format exam. Moreover, the examination results also indicate the need to optimize both the test itself (adjusting the degree of difficulty of the case vignettes) and the corresponding instructional and learning methods (including, for example, the use of computer programmes to complete the death certificate in small group formats in the SkillsLab).

Establishment of two forensic medicine OSCE stations on the subject of external post-mortem examination.

An improvement in quality of medical external post-mortem examinations among others can be achieved by more intensive training of medical students. Modern learning and teaching methods such as e-learning modules and SkillsLab stations should be used for this. The introduction of corresponding methods of assessment such as the OSCE procedure is necessary to test the success of learning. In Halle (Germany), two OSCE stations on the subject of external post-mortem examinations were introduced in 2016. The 'practical external post-mortem examination' station test skills and abilities students have learned during practical external post-mortem examination in small group classes on a simulation doll. At the 'death certificate' station, an original death certificate must be filled in, testing the knowledge, skills and abilities learned in the SkillsLab station and during e-learning. A total of 148 students took part in the test. At both stations, at least two thirds of the students (69.5 and 81.7%) were able to show good or very good test results. In addition to the strengths, a detailed evaluation of the test results showed that there were still deficits in terms of the corresponding courses (e.g. inspection of the neck region in the small group classes), which will have to be remedied in the future. When analysing the test concept and the test implementation, objectivity was nearly perfect. There was a satisfactory internal consistency and stability over 8 months. Ultimately, in addition to several strengths (such as good understanding and transparency of the checklists) the evaluation of the examiners also showed further potential areas for improvement (e.g. harmonisation of the degree of difficulty for the individual rotations) when designing the OSCE stations. Overall, it was possible to determine that the OSCE testing format is a suitable tool to test external post-mortem examination skills and that conclusions about improvements in teaching can also be drawn from this.
