Background
Background
• Patient safety: Increased attention and awareness on a global scale• WHO is developing the International Classification for Patient Safety
(ICPS) together with the World Alliance for Patient Safety
• to represent patient safety workflows • to facilitate international reporting and data exchange• to facilitate international research collaboration
• Novel, ontology-based methodology• Current state of ICPS:
– conceptual framework– field testing, but not yet released– available at http://www.who.int/patientsafety/taxonomy/en/
Structure of the Talk
• ICPS: How does it look like?
• ICPS: What it isn’t
• ICPS: What it is now
• ICPS: What it may be in the future

Three components of ICPS
9. Hazard: a circumstance, agent or action with the potential to cause harm.
10. Circumstance: a situation or factor that may influence an event, agent or person(s).
11. Event: something that happens to or involves a patient.12. Agent: a substance, object or system which acts to produce
change.13. Patient Safety: the reduction of risk of unnecessary harm
associated with healthcare to an acceptable minimum.14. Healthcare-associated harm: harm arising from or associated
with plans or actions taken during the provision of healthcare, rather than an underlying disease or injury.
15. Patient safety incident: an event or circumstance which could have resulted, or did result, in unnecessary harm to a patient.

ICPS Architecture Critique Typology Outlook
ICPS "taxonomy"
ICPS Key Concepts• Classification: an arrangement of concepts into
classes and their subdivisions, linked so as to express the semantic relationships between them.
• Concept: a bearer or embodiment of meaning.• Class: a group or set of like things.Hazard: a
circumstance, agent or action with the potential to cause harm.
• Healthcare: services received by individuals or communities to promote, maintain, monitor or restore health.
• Event: something that happens to or involves a patient.
• Patient: a person who is a recipient of healthcare.
• Agent: a substance, object or system which acts to produce change.
• Patient Safety: the reduction of risk of unnecessary harm associated with healthcare to an acceptable minimum.
• Healthcare-associated harm: harm arising from or associated with plans or actions taken during the provision of healthcare, rather than an underlying disease or injury.
• Patient safety incident: an event or circumstance which could have resulted, or did result, in unnecessary harm to a patient.

ICPS is not…… a taxonomy (ENV 12264:2005, Cornet 2006)
• Semantic nature of hierarchic links are not specified
• Subclass or is-a relation:a class B is a subclass of a class A if and only if all members of B are also members of A (ENV 12264:2005, Horrocks 2003)
ICPS Architecture Critique Typology Outlook
ICPS is not yet…… a classification (ISO 17115:2007, Ingenerf MIM 1998, Madden [WHO-FIC] 2007)
• Criterion of mutually disjoint,exhaustive classes not fulfilled
• more than hundred ICPS concepts occur more than once in different hierarchies – Healthcare Professional occurs both as
a child of People Involved and Person Reporting

with plans or actions taken during the provision of healthcare, rather than an underlying disease or injury.
15. Patient safety incident: an event or circumstance which could have resulted, or did result, in unnecessary harm to a patient.

“Concepts by Class” “Conceptual Framework”
“Key Concepts”
This is a rudimentary, informal ontology• describes terms by their generic properties• close to upper-level ontologies (e.g.
BioTop): “state”, “substance”, “event”, “agent”, “object”, “action”, “quality”.

9. Hazard: a circumstance, agent or action with the potential to cause harm.
10. Circumstance: a situation or factor that may influence an event, agent or person(s).
11. Event: something that happens to or involves a patient.12. Agent: a substance, object or system which acts to produce
change.13. Patient Safety: the reduction of risk of unnecessary harm

ICPS "taxonomy"
This is a complex patient safety model
• Similarity with- workflows- business models
- Ontologically:- complex event type

“Conceptual Framework”
“Key Concepts”
This is a structured data acquisition template consisting of (mostly) binary fieldsCan be described as information model
Hierarchical parents provide context information for fields(but are not superclasses)
ICPS Architecture Critique Typology Outlook
ICPS "taxonomy"
Structure of the Talk
• ICPS: How does it look like?
• ICPS: What it isn’t
• ICPS: What it is now
• ICPS: What it may be in the future
What ICPS may be in the future
• After finishing, ICPS has the potential to be universally accepted as a reporting standard
• The ICPS “key concepts” may become a fully-fledged formal ontology rooted in existing upper-level ontologies and using Semantic Web standards, e.g. OWL
• The ICPS “conceptual framework” can be ontologized in the same line
• The ICPS reporting template ("taxonomy") may be fully described in terms of ICPS’s ontological core
• but…
ICPS Architecture Critique Typology Outlook
Open issues
• The needs for semantically interoperable patient-safety relevant event reporting is essentially different from the reporting of diseases
• For the latter, the format of a statistical classification is adequate (ICD-10)
• Is the format of a reporting template adequate for the purpose ICPS is devised for?
• Is it necessary to transform the ICPS tree into a real taxonomy or classification structure?
• Terms like “taxonomy”, “classification” should be used thoughtfully
