Facilitating Cross-National Comparisons of Indicators for Patient ...

DELSA/ELSA/WD/HTP(2008)1based research effort that focuses on examining specific data elements and coding issues that currentlyimpede international comparability of patient safety indicators based on hospital administrative data. Next,an experimental calculation of indicators is to be performed by a group of volunteering countries.10. This manual was originally designed to support the calculation of patient safety indicators in agroup of countries volunteering to participate in the validation of the methodology. However it isanticipated that the material presented will also be of interest to a wider audience, including researchersand experts interested in the technical background and construction of the Patient Safety Indicators andother countries looking to develop internationally comparable health care quality indicators.11. The manual provides:• Generic coding and calculation instructions related to national hospital administrative databases,• Cross walk from ICD 9 to ICD 10 codes for each indicator,• Detailed definitions for calculation of indicators,• Flow charts for visualising the calculation process, and• Quick-step overview of essential tasks for data preparation.12. It is anticipated that further revisions to the methodology presented in this manual will be madebased on the collective experiences of those using the manual over time.9
