OBJECTIVE To explore the potential for international comparison of patient safety as part of the Health Care Quality Indicators project of the Organization for Economic Co-operation and Development (OECD) by evaluating patient safety indicators originally published by the US Agency for Healthcare Research and Quality (AHRQ). DESIGN A retrospective(More)
BACKGROUND Patient Safety Indicator (PSI) 11, or postoperative respiratory failure, was developed by the US Agency for Healthcare Research and Quality to detect incident cases of respiratory failure after elective operations through use of ICD-9-CM diagnosis and procedure codes. We sought to determine the positive predictive value (PPV) of this indicator.(More)
OBJECTIVE To improve the international comparability of patient safety indicators based on administrative hospital data, adjustment of country-specific rates by a proxy measure of diagnostic coding intensity was tested. DATA SOURCES Secondary data (numerator and denominator counts of patient safety indicators) based on adults discharged from acute care(More)
Patients and health insurances are increasingly interested in the quality of care provided by hospitals. Quality indicators are often used to evaluate the quality of inpatient treatment. Most of these evaluations require the collection of additional data. The patient safety indicators (PSI) introduced by the Agency for Healthcare Research and Quality (AHRQ)(More)
This paper outlines the approach that the WHO's Family of International Classifications (WHO-FIC) network is undertaking to create ICD-11. We also outline the more focused work of the Quality and Safety Topic Advisory Group, whose activities include the following: (i) cataloguing existing ICD-9 and ICD-10 quality and safety indicators; (ii) reviewing ICD(More)
OBJECTIVE As part of the WHO ICD-11 development initiative, the Topic Advisory Group on Quality and Safety explores meta-features of morbidity data sets, such as the optimal number of secondary diagnosis fields. DESIGN The Health Care Quality Indicators Project of the Organization for Economic Co-Operation and Development collected Patient Safety(More)
Hospital-based medical records are abstracted to create International Classification of Disease (ICD) coded discharge health data in many countries. The 'main condition' is not defined in a consistent manner internationally. Some countries employ a 'reason for admission' rule as the basis for the main condition, while other countries employ a 'resource use'(More)
The World Health Organization (WHO) plans to submit the 11th revision of the International Classification of Diseases (ICD) to the World Health Assembly in 2018. The WHO is working toward a revised classification system that has an enhanced ability to capture health concepts in a manner that reflects current scientific evidence and that is compatible with(More)
BACKGROUND Existing administrative data patient safety indicators (PSIs) have been limited by uncertainty around the timing of onset of included diagnoses. OBJECTIVE We undertook de novo PSI development through a data-driven approach that drew upon "diagnosis timing" information available in some countries' administrative hospital data.

Nitrous oxide is delivered during most cases of general anaesthesia. Though it has a history of approx. 150 years there is no univocal understanding about its clinical potency. Research studies during the last 10 years support, however, the view that 1. the potency of nitrous oxide in the clinical settings is only 1/3 of the potency as estimated from the(More)
