Rachel EllawayNorthern Ontario School of Medicine

The world’s most boring video...

Why did we start working on this?

Example from Calgary’s archive

KISS

Key Kinetic Komponents

– Restrict the video to – Key Kinetic Komponents

Modular and Re-usable

Access at Point-of-Care

No talking heads

– Doctors are not actors– Voice over to fit– Multiple languages

Don’t tie your audience in knots

Getting the point across

Objects and Wrappers

• Pocketsnips videos are more than the video• Breadbaskets:

– Context and advice– Mix of contextual data and metadata– Procedural rather than object model

• Present breadbasket meaningfully with video– Ooyala?

• www.ooyala.com/

Healthcare LOM

• MedBiquitous ANSI candidate standard based on IEEE 1484.12.1 Standard for Learning Object Metadata:– General– Lifecycle– Metametadata– Technical– Educational– Rights– Relation– Annotation– Classification

• Additional healthcare LOM section (all elements optional)

Pocketsnips Metadata

• Based on HealthCare LOM• Additional elements:

– Pocketsnip• video• indications• precautions• resources• landmarks• proc_steps• tips• licensing• complications• patient_ed

Video

• File: URL or package reference• Bookmarks - information relevant to steps on the timeline

– Bookmark• ID: unique identifier• start_time: from video start in seconds or milliseconds• end_time: delta from start_time (s or ms)• description: text or xhtml description of the information

(if including formatting and supporting media)

• Candidate spec: Synchronized Multimedia Integration Language (SMIL) - now at version 3.0: http://www.w3.org/AudioVideo/

Indications

• Purpose of activity (1 or more)– Diagnostic– Therapeutic

• Clinical condition (1 or more)• Pathophysiology (1 or more)• Utility of skill (1 or more)

– Diagnostic– Therapeutic

• Candidate specs: LOM classifications using MeSH and ICD-10

Precautions

• Risks - candidate spec: LOM annotations

• Allergies - candidate spec: LOM annotations

• Precautions - candidate spec: LOM annotations

• Contraindications - candidate spec: LOM annotations

• Common errors - candidate spec: LOM annotations

Licensing

• Liability: e.g. clinical mistake blamed on video clip - need to include in license

• Consent: no good model in general use to track consent –

– see CHERRI

• Area needs more work for standards …

– Conjoint activity between AAMC & AFMC initiated at this meeting

Derivatives & Mashups

Resources

• Equipment needed (stethoscope etc)– Description– Purpose– Mandatory/optional– Setup

• Person– Role– Skillset

LOM annotations - but questions of insufficient structure - extension here?

Landmarks

• Landmark– Description– Use LOM classification with

MeSH or XPATH relation to SkelML/other service

• Patient Position– description - controlled

vocabulary

LOM annotations - but very amenable to extension here

Procedural Steps

• Duration: for whole procedure (LOM 5.9 typical learning time vs LOM 4.3 duration)

• Confirmation of location - ?• Steps

– Step• Order• ID• Description• mandatory/optional• prior_conditional

Procedural models do exist (IMSLD, MVP, SCORM, IMS-SS etc) but unclear as to best candidate and suitability

Tips

• Tip– Description– role_from– role_to/target– type - controlled vocab - billing, safety, comfort,

easiness, alternative_approach

LOM annotations - but questions of insufficient structure - extension here?

Complications

• Complication– Description– timing/occurrence– minor/serious – cross-linked with precautions

LOM annotations - but questions of insufficient structure - extension here?

Patient Education

• Item– Description– mandatory/criticality– required_action– timing/sequencing

LOM annotations - but questions of insufficient structure - extension here?

Issues

• This is not a standard– How to define and refine– How to share and interoperate

• Spec (HealthcareLOM) vs open (RDF)• Can build upon a range of existing models (LOM, SMIL, MeSH,

ICD-10 etc) but still gaps

• Packaging• Procedural vs object models

– for content or hybrid content+process objects

Closure

The suturing video… ?

Simple

Focused

Adaptable

Quick

Cheap to do

cheaper if shared

Freely available

Free Nelson Mandela

Video plus …

Structured breadbasket

Leverage existing standards … but some work needed
