Live video streaming and webcasting in
dermatology education

• Maria Gonzalez
• Sonia Maurer
• Nan Zhang

2
Definitions

• Live video streaming or video-conferencing
• Synchronous method of communicating between
  dispersed groups
• Webcasting
• Broadcast of video, live or on-demand, using
  streaming technology across the world wide web

3
The Project

• Dermatology Surgical Skills Projects I and II
• Project I
• Video Linkage of surgical theatre to seminar room
• Project II
• Use of video capture software (Mediasite) to
  stream surgical sessions and lectures online and
  store them for on-demand viewing

4
Context

• Teaching and learning of surgical skills in
  dermatology is important
• Historical standard for this is apprenticeship
  model with direct participation in the Operating
  theatre
• See one, do one, teach one

5
Context

• Limited access rationing of training in certain
  skills
• Use of live video/webcasting democratises this
  process
• Enhanced opportunity to see one
• Previously undergraduates did not have access to
  surgical theatres in dermatology
• Limited number of postgraduates had access in an
  ad hoc fashion

6
Format of live surgical sessions

• A work in progress
• Surgeon wears microphone to allow communication
  with seminar room
• Speakers on wall of theatre allows all in theatre
  to hear comments from students
• Moderator in the seminar room
• Surgeon discusses case and puts questions to the
  group as procedure is carried out
• Group also allowed to ask questions or comment

Main challenges

• Getting co-operation of NHS staff
• Having access to a technician who understands the
  technology and can be available for all sessions
• Must have patient consent and co-operation
• Ensuring audience remembers that all comments can
  be heard by patient

11
Main challenges

• Keeping students engaged
• Skill and interactivity of surgeon
• Facilitation skills of moderator
• Always having new and interesting cases
• Keeping session at the correct length
• Keeping surgeon engaged

12
Critical success factors

• Well trained / reliable IT staff
• Skilled and confident demonstrator
• Good facilitator avoid television response
• Developmental approach to sessions cases should
  not be ad hoc

13
Webcasting of lectures

• All lecturers speaking the department of
  dermatology are asked for permission to video
  their lecture
• Creation of a database of expert lectures

14
Key challenges

• Because of use of patient images doctors are
  often very unwilling to have their lecture videoed

15
Main benefits of project

• Anywhere, anytime access
• Videos can be paused, rewound etc allowing
  difficult aspects of surgical procedures to be
  viewed until viewer is happy they have understood
  not possible in live observation
• Students less anxious about having to take notes

16
Main benefit

• Democratisation of access to knowledge
• Groups benefiting
• Undergraduates
• Post graduates in full time courses
• All dermatology trainees and consultants in Wales
• Alumnus Dermatology Continuing Professional
  Development Society
• Distance learners

17
The future

• DOH funded project to bring surgical teaching to
  trainees throughout UK
• Linking up with other universities e.g. in
  developing countries
• CPD for dermatologists licence to practice
• Assessment of registrars DOPs (Direct
  observation of procedures)

Requirements

• Live video link from operating theatre to seminar
  room, with 2-way audio
• Software to stream sessions live to Internet
• Software management system for later on-demand
  access to recordings
• Rarely been done before

20
Where to start

• Simple operating theatre video links are not new

In addition to video link

• Live streaming
• Content management system
• User management system control access to
  recorded content
• Record seminar room lectures (PowerPoint slides
  and video of lecturer)
• Flexible screen template

22

• Identified Mediasite and Echo 360
• Mediasite sent links to USA surgery video
• Echo 360 seemed put off by project
• Sent requirements to AV firms (incl. Mediasite
  links)
• Site visits arranged by VideoSouth, Touchvision
  and Drake

23
VideoSouth

• Operating Theatre
• One high quality camera on moveable arm
• Radio mic
• Preview monitor

• Recommended Encoded Media

27
Decision

• Time pressures looming
• VideoSouth / Mediasite combination was only
  system to inspire confidence
• Mediasite offered us a joint-purchase deal with
  PGMDE
• Mediasite hosted on our dedicated server (shared
  with PGMDE)

Seminar Room lecture recording
29
To record lectures

• In advance LT logs into Mediasite management
  system and enters details of recording
• At time of lecture administrator calls up the
  session on Mediasite computer, checks camera
  position, pins on mic and clicks Record
• Recordings automatically available on system

30
Surgery Recording
31
To record surgery

• LT schedules presentation in Mediasite (specify
  template)
• LT checks camera and mic in operating theatre
• Seminar room open presentation in Mediasite,
  moderator mic, click record
• Live streaming to office PC

32
Integration Options

• How to integrate with existing environments?
• Mediasite user management which username and
  password?

33
Integration Options

• VLE users already have username and password
• Mediasite can be integrated with Active Directory
• Complicated to implement (Desire2Learn / Moodle)
• AD doesnt automatically give Single Sign On

34
Integration Solutions

• Simulated Single Sign On
• Send generic username and password from HTML page
  within VLE, using hidden fields
• One generic log-in for each group of users
• Gives access to videos they are allowed to see
• Accessed from VLE, with username and password
  given on page

35
Student Feedback

• It is a good introduction to dermatological
  surgery
• Very useful as different surgical skills like
  local anaesthetic injections, excision technique
  and suturing technique can be learnt.
• It was very nice that the surgeon was
  communicating with us, asking us questions and
  explaining the procedure as well.
• It is useful because it allows one to understand
  what is happening during the procedure and why
  things were being done.
