- A Broad Overview -

• Dalhousie University

2
Why use CBR for healthcare?

• Operative (tacit) knowledge (experience) is
  collected during every day practice and stored as
  cases.
• It requires a long learning process for a health
  professional to be an expert from a novice.
• Reasoning with cases corresponds with the
  decision making process of physicians.

• Heart Failure (CASEY)
• Pulmonology (MEDIC)
• Dysmorphic Syndromes (GS.52)
• Kidney Function (ICONS)
• Ultrasonography (FM Ultranet)
• Histopathology (IDEM)
• Breast Biopsy Outcome (BI-RADS)

• deals with heart failure diagnosis
• developed as a doctoral thesis by Phyllis Koton

How is CBR used in healthcare?

• FLORENCE
• deals with healthcare planning for nursing
• It fulfills three basic planning tasks
• Diagnosis What is the current health status of
  this patient?
• Prognosis How may the health status of this
  patient will be in the future?
• Prescription How may the heath status of this
  patient be improved?
• It combines a rule-based approach and a
  case-based approach

How is CBR used in healthcare?

• ICONS offers only diagnostic and prognostic
  support, the user decides the relevance of all
  displayed information. (Retrieve-only)

Problems of CBR for healthcare applications

• A representation form for cases
• Associative memory (Stefan)
• An appropriate retrieval algorithm
• Much research has been undertaken
• Adaptation problem Bottleneck
• Adaptation rules and operators
• Constraints
• Abstraction
• Compositional adaptation (Raza)
