Monitoring health IT integration--the effect of an EMR on laboratory service timeliness across six Australian hospitals.

Andrew Georgiou, Elia Vecellio, Ling Li, Alex Eigenstetter, Roger Wilson, George Toouli, Johanna I Westbrook,

The Electronic Medical Record (EMR) incorporates computerised provider order entry systems which allow clinicians to order diagnostic tests electronically, thus eliminating the need for cumbersome handwritten orders. In many situations the EMR relies on a manual transition of information across systems (e.g., integration with the Laboratory Information System). This study, ... Read more >>

Examination of changes in pathology tests ordered by Diagnosis-Related Group (DRGs) following CPOE introduction.

Elia Vecellio, Andrew Georgiou, George Toouli, Alex Eigenstetter, Ling Li, Roger Wilson, Johanna I Westbrook,

Electronic test ordering, via the Electronic Medical Record (EMR), which incorporates computerised provider order entry (CPOE), is widely considered as a useful tool to support appropriate pathology test ordering. Diagnosis-related groups (DRGs) are clinically meaningful categories that allow comparisons in pathology utilisation by patient groups by controlling for many potentially ... Read more >>

Volume, rates, source and types of add-on pathology test requests across five hospitals.

Elia Vecellio, Andrew Georgiou, George Toouli, Johanna I Westbrook,

Add-on test requests, where a clinician requests further test assays on an existing specimen, contribute disproportionately to pathology service workload. However, little research has quantified the volume, rates, source or types of add-on tests. This study provides a descriptive analysis of add-on testing within a pathology service serving five hospitals.We ... Read more >>
