topic advisory groups
Topic Advisory Groups
  • “Organize the work for the revision of ICD in a specified domain based on procedural, terminologic and taxonomic guidelines of the revision process”
  • “Advise WHO in all steps leading to the revision of the topic sections of ICD”
  • Most TAGs work “vertically” in relation to existing ICD-10 chapters (e.g., mental health, dermatology)
safety and quality
Safety and Quality
  • A horizontal theme that applies across all chapters (not just in the external causes/injury domain)
  • An ICD-11 ‘use case’ (analogous to coding mortality to track causes of death, coding morbidity for payment)
  • Measurement using ICD supports surveillance, trending, benchmarking, research, quality improvement

the need for a q s tag
The need for a Q&S TAG
  • ICD-10 challenged the safety/quality use case (b/c existing tools were for ICD-9)
    • Iezzoni’s Complication Screening Program
    • AHRQ Quality Indicators/OECD
  • Other classification initiatives
    • NQF Serious Reportable Events
    • International Classification for Patient Safety
    • AHRQ Common Formats
  • Best to inform ICD-11 writing through a safety/quality lens, building on ICD-9 and 10
tag work plan
TAG Work Plan
  • Co-chaired by William Ghali (U. of Calgary) and Harold Pincus (Columbia U.)
  • Membership includes experts from N. America, Europe, Asia, Australia
  • Funding from CIHI and AHRQ Conference Grant program secured
  • Face-to-face meetings:
    • June 2010
    • Feb 24-25 and Nov 15-16, 2011
    • April 3-4 and Nov 7-8, 2012
tag work plan1
TAG Work Plan
  • Focus of work in 5 general areas:
    • Develop an inventory of existing Q&S indicators, and consider potential new indicators, to ensure applicability in ICD-11
    • Review concepts of ICPS for applicability to ICD-11
    • Restructure the coding scheme for health care related injuries in chapters 19/20
    • Review and refine volume 2 coding rules for ICD-11
    • Review and critique ICD-11 alpha/beta drafts
    • Develop strategy for field testing
  • Collaboration with External Causes and Injury TAG, Morbidity TAG, Revision Steering Group
specific recommendations to date
Specific recommendations to date
  • Main condition coding
    • “Reason for admission” versus “resource consumption”
    • Former approach more consistent with Q&S use case
    • Latter approach requires complex decision logic that may not have sufficient inter-observer reliability, compromising comparability across providers and countries
  • Diagnosis timing indicator
    • Crucial to flag complications of hospital care
    • Simpler classification scheme (2 or 3 categories) favored
    • Suffix/prefix modifier within code (related to concepts of “personal history of,” “family history of,” etc.)
specific recommendations to date1
Specific recommendations to date
  • ICPS (not fully developed)
    • Ideally, all of the ‘incident type’ categories from ICPS should map to codes in ICD-11 (what about “near misses”?)
    • This requires a “virtual chapter” structure
  • Number of diagnosis fields must be sufficient to support reporting of all significant complications that arise during an episode of care, in addition to significant risk factors
    • Empirical work using data from OECD
specific recommendations to date2
Specific recommendations to date
  • Clustering would allow post-coordination of diagnostic concepts that cannot be clearly linked in ICD-10 (or are linked using combination codes)
    • The cause of injury (e.g., a substance/drug, a procedure/intervention, or a device)
    • The mechanism or mode of injury (i.e., the mechanism by which the factor caused injury, as currently defined in Chapter 20)
    • The actual injury or condition that resulted (i.e., anatomic or physiologic abnormalities, as currently defined in Chapters 1-19)
    • Could accommodate “place,” “activity at time of injury”
example problem
Example problem
  • ICD-9/CM: 998.2, “Accidental puncture or laceration during a procedure”
  • ICD-10: T81.2, as above “NEC”
  • ICD-10-CM: Many chapter-specific codes, e.g., I97.5, “Accidental puncture and laceration of a circulatory system organ or structure during a procedure”
    • I97.51, “…during a circulatory system procedure”
    • I97.52, “… during other procedure”
example of clustering in icd 11
Example of clustering in ICD-11
  • Concept 1: Injury or harm
    • Injury of heart with haemopericardium (S26.0)
  • Concept 2: Mechanism or mode of injury or harm
    • Mechanical cut or puncture
  • Concept 3: Cause of injury or harm
    • …during endovascular surgical procedure
  • Suffix for diagnosis timing
  • 7th digit clustering flag on all related diagnoses
other considerations
Other considerations
  • “Complication of other aspect of care” (e.g., physiotherapy)
  • “Observation for suspected condition” (with no actual harm)
  • Rationalization of substance-related concepts in a single chapter
  • Mortality use case
  • Backward compatibility with ICD-10 (and country-specific versions)
methodological work
Methodological work
  • Overview (Ghali et al.)
  • Defining main condition or “principal diagnosis” for international comparability (Quan et al.)
  • Number of diagnosis fields (Drősler et al.)
  • Defining diagnosis timing (“present on admission” for international comparability (Sundararajan et al.)
quality and safety tag
Quality and Safety TAG
  • An exciting mandate – May 2015!
  • Real potential for ICD enhancement for quality measurement and data extraction
  • Dialogue/interaction with all other TAGs
  • Develop international consensus on data standards and methods
  • Harmonize data definitions
  • Linkages with WHO, OECD, AHRQ, CIHI
questions and discussion
Questions and discussion
  • Please e-mail us:
    • wghali@ucalgary.ca
    • pincush@nyspi.columbia.edu
    • psromano@ucdavis.edu
  • Questions for your consideration:
    • How could ICD be improved in ICD-11 to facilitate measurement of quality and safety?
    • How can we make ICD easier to use but also more useful for research and QI?
