摘要
Objective To assess if the Agency for Healthcare Research and Quality patient safety indictors (PSIs) could be used for case findings in the International Classification of Disease 10th revision (ICD-10) hospital discharge abstract data. Design We identified and randomly selected 490 patients with a foreign body left during a procedure (PSI 5foreign body), selected infections (IV site) due to medical care (PSI 7infection), postoperative pulmonary embolism (PE) or deep vein thrombosis (DVT; PSI 12PE/DVT), postoperative sepsis (PSI 13sepsis)and accidental puncture or laceration (PSI 15laceration) among patients discharged from three adult acute care hospitals in Calgary, Canada in 2007 and 2008. Their charts were reviewed for determining the presence of PSIs and used as the reference standard, positive predictive value (PPV) statistics were calculated to determine the proportion of positives in the administrative data representing true positives'. Results The PPV for PSI 5foreign body was 62.5% (95% CI 35.4% to 84.8%), PSI 7infection was 79.1% (67.4% to 88.1%), PSI 12PE/DVT was 89.5% (66.9% to 98.7%), PSI 13sepsis was 12.5% (1.6% to 38.4%) and PSI 15laceration was 86.4% (75.0% to 94.0%) after excluding those who presented to the hospital with the condition. Conclusions Several PSIs had high PPV in the ICD administrative data and are thus powerful tools for true positive case finding. The tools could be used to identify potential cases from the large volume of admissions for verification through chart reviews. In contrast, their sensitivity has not been well characterised and users of PSIs should be cautious if using them for quality of care reporting' presenting the rate of PSIs because under-coded data would generate falsely low PSI rates.
