Swiss health care system OECD / WHO 2011
• Performing well, but costly - in general and for a sizable number
of persons/families
• Needs to face increasing burden of chronic diseases in an aging
population: increasing volume of care, few integrated care -
networks
• Improve healthcare information (quality of care) • Improve
assessment of quality of care and of healthcare
technologies • Shortage of healthcare professionals • Too many
hospitals / hospital beds • Lack of coordination in prevention and
health promotion • Insufficient governance and coordination in
healthcare system
Swiss health care system Quality of care – law
• In the framework of the mandatory healthcare insurance, all paid
care must be effective, appropriate and economical (Art. 32
LAMal)
Swiss health care system Quality of care – law
• Warranting quality (Art. 58 LAMal) … the Federal Council (FC) can
manage to organise scientific and systematic assessments to monitor
and warrant appropriateness and quality of care …
– The following information should be communicated: …. f. quality

Quality and safety indicators based on routinely collected data /
administrative data – Potentially avoidable re-hospitalisation –
Potentially avoidable surgical re-intervention – Swiss Anaesthesia
Databank (ADS) – Patient Safety Indicators (AHRQ)
To use selected Patient Safety Indicators (PSI - AHRQ) and their
algorithm refinement for assessing the impact of DRG implementation
in Switzerland (SNF - Sinergia)
1. To explore and document the frequency, variations and potential
biases of PSI, using Swiss hospital data collected by the Federal
Office of Statistics
2. To evaluate trends in PSI in Swiss hospitals 2008 – 2015 Impact
of 2012 changes in DRG implementation
3. To assess the accuracy of a subset of PSI
Quality and safety indicators

• Contribution to new classification – ICD-11 – WHO – Topic
Advisory Group (TAG)
on Quality and safety • Conceptual and practical developments
ICD-11 for quality and safety Overview of the WHO Quality and
Safety Topic Advisory Group (WHO-TAG Q&S)
i. Cataloguing existing ICD-9 and ICD-10 quality and safety
indicators
ii. Reviewing ICD morbidity coding rules for main condition,
diagnosis timing, numbers of diagnosis fields and diagnosis
clustering
iii. Substantial restructuring of the health-care related injury
concepts coded in the ICD-10 chapters 19/20
Ghali WA et al. Int J Qual Health Care 2013;25:621-5
ICD-11 for quality and safety Overview of WHO-TAG Q&S
iv. Mapping of ICD-11 quality and safety concepts to the
information model of the WHO's International Classification for
Patient Safety and the AHRQ Common Formats
v. Review of vertical chapter content in all chapters of the ICD-11
beta version
vi. Downstream field testing of ICD-11 prior to its official
release
Ghali WA et al. Int J Qual Health Care 2013;25:621-5
WHO-TAG Q&S International variation in the definition of
‘main
condition’ in ICD-coded health data
• ‘main condition’ not defined in a consistent manner
internationally – ‘reason for admission’ – ‘resource use’
• a few countries have recently transitioned from one of these
approaches to the other
• definition of ‘main condition’ matters (DRG’s, risk
adjustment)
Quan H et al. Int J Qual Health Care 2014;26:511-5
WHO-TAG Q&S
• International variation in the definition of ‘main condition’ in
ICD-coded health data
• WHO-TAG Q&S proposes a method of harmonizing the
international definition
• to improve health data comparisons across countries and hospitals
consistently
• inter-observer reliability of alternative harmonization
approaches should be evaluated
Quan H et al. Int J Qual Health Care 2014;26:511-5
WHO-TAG Q&S How many diagnosis fields are needed to
capture
safety events in administrative data? Findings and
recommendations
• What is the optimal number of secondary diagnosis fields for
meta-analyses?
• PSI information from administrative hospital data of 19-20 OECD
countries in 2009 and 2011 (+ CA &FL in USA)
• Comparison of PSI rates in 3 countries with expanded # of
secondary diagnosis fields vs 6 countries with limited # secondary
diagnosis fields
Drösler SE et al. Int J Qual Health Care 2014;26:16-25
WHO ICD-11 TAG Q&S - number of secondary diagnoses fields •
Increased # of secondary diagnosis fields not
associated with overall increase in PSI rates • High proportions of
PSI-related diagnoses appeared
beyond the 6th secondary diagnosis field • Distribution of 3 PSI in
CA and FL
– 89-90% of central venous catheter infections and – 97-99% of
retained foreign bodies and accidental
punctures or lacerations captured within 15 secondary diagnosis
fields
Drösler SE et al. Int J Qual Health Care 2014;26:16-25
WHO ICD-11 TAG Q&S
Capturing diagnosis-timing in ICD coded hospital data
• narrative literature review • scan of national experiences
focusing on
countries currently using timing flags • series of meetings •
formal recommendations regarding diagnosis-
timing reporting
Sundararajan V et al. Int J Qual Health Care. Accepted
WHO ICD-11 TAG Q&S diagnosis-timing in ICD hospital data
Recommendations
• yes/no classification of ‘arising after admission’ • permitted
designations of ‘unknown or clinically
undetermined’ – to facilitate coding while providing flexibility
when
there is coding uncertainty • clear coding standards and
guidelines
– ongoing coder education • ensure reliability of diagnosis-timing
flag
Sundararajan V et al. Int J Qual Health Care. Accepted
WHO ICD-11 TAG Q&S New concept to capture “harm & injuries”
Develop a new conceptual approach to
capturing healthcare-related harms and injuries in ICD-coded
data
• Four categories of source of “event” a) Medications and
substances taken for
therapeutic purposes b) Procedures c) Devices d) Other aspects of
care
WHO ICD-11 TAG Q&S New concept to capture “harm &
injuries”
• Proposed multiple coding approach • Each source of harm coded
with a combination
of codes • Use of new code clustering in ICD-11
– “cause” of harm – “mode or mechanism” of harm – “actual injury or
harm” that resulted from
the event
Harm" that resulted
from the event
“Mode or Mechanism” of harm e.g. overdose/underdose for
substances
e.g. accidental perforation for procedures e.g.
dislodgement/malfunction for devices e.g. mismatched blood used in
transfusion
for other aspects of care
WHO ICD-11 TAG Q&S New concept to capture “harm &
injuries”
• Proposed information model provides a more flexible, yet still
simple and non-duplicative, approach to recording quality and
safety events in ICD-coded data
• Linked to broader proposal from the Injury TAG for
revision/enhancement for the external cause and injury
chapters
WHO ICD-11 TAG Q&S New concept to capture “harm &
injuries”
• Introduction of a diagnosis-timing capacity (i.e., distinguishing
present on admission vs. arising during hospital stay)
• Revised set of codes in ICD-11’s Chapter 24 capturing “Factors
influencing health status and contact with health services”
