Introduction
v Pediatric cancer survivors face a lifetime of follow-up care v Cancer survivors are provided with a self-management
program with information on
v how to interpret and manage symptoms v how to make healthy lifestyle choices v how to deal with specific situations v how to manage their therapy plan
v It is important to engage patients in the design of this follow-
up program
v Personalize it with respect to their conditions and preferences, as this
will improve overall satisfaction
Shared Decision Making (SDM)
v Engaging patients in the care process has been shown to
lead to better communication, better task orientation and improvement of quality of life
v Key to SDM is the incorporation of evidence
v Pertinent aspects of a Clinical Practice Guideline (CPG) are discussed
with the patient
v Through this process a self-management program is formulated
SDM is a patient-centered care paradigm where clinicians and patients leverage the best available evidence to make decisions together about the best management of their care
YouCan System
v The YouCan system is designed to facilitate long-term follow-
up care of survivors of childhood cancer
v It is based on the concept of SDM, using a computerized
version of a cancer follow-up CPG
v “Guideline for Long Term Follow-Up for Survivors of Childhood,
Adolescent, and Youth Adult Cancers”
v YouCan personalizes the CPG based on the patient’s
v Current therapeutic regiment v Health v Psychosocial behavior
v Recommends relevant, evidence-informed self-management
activities
YouCan System
Methods
v Knowledge-management approach using semantic web
technologies
v YouCan is comprised of three components
1.
CPG Computerization
2.
CPG Execution

Diary Composition
CPG Computerization
v We used our own ontology to computerize the CPG, resulting
in the YouCan Ontology (in OWL-DL).
v Serves as the basis for the SDM rules that guide the SDM
session
v The premise of a rule is a combination of therapeutic agents (drugs)
together with patient attributes and preferences
v Body of the rule contains recommendations from the CPG v Recommendations are classified into three categories
v Things you need to know v Things you need to do v Things to talk to your doctor about
CPG Execution
v SDM Rules are executed based on the survivor’s profile
v Therapeutic agents used v Personal attributes v Management preferences
v A Pellet reasoner executes the SDM rules, applying the
patient information to the SDM rules to extract a pertinent set
- f recommendations
Diary Composition
v A diary template is prepared with the following sections
v Introductory information v diagnosis summary v treatment summary v self-management recommendations v information about conditions and potential complications v next steps
v Sections are populated by the SDM rules and
recommendations are embedded within the diary
Results
v The knowledge modeling was done by two domain experts
v Over 600 SDM rules were created v 110 drug side-effect interactions for 22 therapeutic agents
v Using the SDM rules and the template, a 5-10 page self-
management diary is produced and given to the patients.
v Consider the following patient as an example:
v 15 year-old male, diagnosed with Astrocytoma in March 2001 v Received chemotherapy, radiotherapy and surgery, beginning in
January 2001 and ending in December 2004
v I’ll start with an example of a single rule set (Bleomycin, a
chemotherapy agent), and then present his entire diary
Bleomycin
v Some rules fire
regardless of patient information
v Other rules are
dependent on:
v Dose v Patient
demographics
v Comorbidities v Concurrent
Treatments
Diary Example: Pages 1 and 2
Evaluation
v In phase 1, domain experts evaluated the SDM rules for their
clinical validity
v Complete, some rules were adjusted, rules base is confirmed as valid
v In phase 2, rules execution was evaluated for completeness
and consistency
v Rules were manually checked by knowledge-modelling experts v Sample clinical cases were passed through the system v Rules based is now confirmed as accurate
v In phase 3, sample diaries will be field tested with physicians,
nurses and patients for content and layout
v Ethics received, study is currently underway
v In phase 4, a pilot study will be conducted with the Children’s
hospital in Halifax
Discussion
v Management of pediatric cancer survivors is challenging v The use of SDM principles allows engagement in care plan v The YouCan framework produces a personalized self-
management diary that facilitates the SDM process
v The diary is being embedded within the CYP-C portal (an
electronic health record for the clinical management of all pediatric cancer cases in Canada)
v The SDM based and CPG-guided self-management service can be
