RT Journal Article SR Electronic T1 Accuracy of screening tools for Pap smears in general practice JF BMJ Health & Care Informatics FD BMJ Publishing Group Ltd SP 555 OP 559 DO 10.14236/jhi.v23i3.835 VO 23 IS 3 A1 Catherine Harding A1 Alexa Seal A1 Geraldine Duncan A1 Ronald Huynh A1 Robert McWilliam A1 Louis Pilotto A1 Stephanie Blake A1 Ken Mackey YR 2016 UL http://informatics.bmj.com/content/23/3/555.abstract AB Background Data extraction tools (DETs) are increasingly being used for research and audit of general practice, despite their limitations.Objective This study explores the accuracy of Pap smear rates obtained with a DET compared to that of the Pap smear rate obtained with a manual file audit.Method A widely available DET was used to establish the rate of Pap smears in a large multi-general practice (multi-GP) in regional New South Wales followed by a manual audit of patient files. The main outcome measure was identification of possible discrepancies between the rates established.Results The DET used significantly underestimated the level of cervical screening compared to the manual audit. In some instances, the patient file contained phone/specialist record of Pap smear conducted elsewhere, which accounted for the failure of the DET to detect some smears. Those patients who had Pap smears whose pathology codes differed between time intervals, i.e. from different pathology providers or from within the same provider but using a different code, were less likely to have had their most recent Pap smear detected by the DET (p < 0.001).Conclusion Data obtained from DETs should be used with caution as they may not accurately reflect the rate of Pap smears from electronic medical records.How this fits in DETs are increasingly being used for research and audit of general practice.
