Features of Medical Education

• Audio-visual senses and methods • Patient-oriented training• Interaction, communication• Case-based learning/working• Emergency and rare disease: Problem

Bedside Teaching Today

Students come to patient (up to 20).

Problem Specification

• Patient‘s presence too short (5 days) • Too many students (20 students/bed)• Stress for patients (i. e. obstetrics,

pediatry)• No access for students (if patient in

emergency room)• Emergency treatment can not wait for

students

Solution: MeduOnCall

• Students don‘t need to come to patient

• Bedside teaching anywhere, anytime

• Students will be alarmed by SMS• Using WLAN and Notebook and• Audio-video conferencing

MeduOnCall Scenario

Aims of the Project

• Do not replace beside teaching• But improve it• Patients with rare disease or cases

with didactical value• Interdisciplinary scenarios• Concurrent use of real cases and

case data bases and other information sources.

Requirements

Data protection

Smooth workflow

Anytime, anywhere

Integration in routine work

Reducing stress for patients

Acceptance

• Students accepted the new learning method

• Students have no problem using the new software and hardware

• The most important factor is the audio quality

Integration

• No integration problem (in routine work).

• Collision with other mandatory lectures

Conclusion

• Acceptance of students exists• Audio quality is the most important factor• Stress for patients can be reduced• Organisation problems must be solved:

– No charging station for notebook battery– Notebook too heavy (3 Kilo, under 1000 €)
