  • Title: 2008 Niday Perinatal Database quality audit: report of a quality assurance project.
    Author: Dunn S, Bottomley J, Ali A, Walker M.
    Journal: Chronic Dis Inj Can; 2011 Dec; 32(1):32-42. PubMed ID: 22153174.
    Abstract:
    INTRODUCTION: This quality assurance project was designed to determine the reliability, completeness and comprehensiveness of the data entered into Niday Perinatal Database. METHODS: Quality of the data was measured by comparing data re-abstracted from the patient record to the original data entered into the Niday Perinatal Database. A representative sample of hospitals in Ontario was selected and a random sample of 100 linked mother and newborn charts were audited for each site. A subset of 33 variables (representing 96 data fields) from the Niday dataset was chosen for re-abstraction. RESULTS: Of the data fields for which Cohen's kappa statistic or intraclass correlation coefficient (ICC) was calculated, 44% showed substantial or almost perfect agreement (beyond chance). However, about 17% showed less than 95% agreement and a kappa or ICC value of less than 60% indicating only slight, fair or moderate agreement (beyond chance). DISCUSSION: Recommendations to improve the quality of these data fields are presented.
