Missed detection of significant positive and negative shifts in gentamicin assay: implications for routine laboratory quality practices.

Gus Koerbin, Jiakai Liu, Alex Eigenstetter, Chin Hon Tan, Tony Badrick, Tze Ping Loh,

Introduction:A product recall was issued for the Roche/Hitachi Cobas Gentamicin II assays on 25th May 2016 in Australia, after a 15 - 20% positive analytical shift was discovered. Laboratories were advised to employ the Thermo Fisher Gentamicin assay as an alternative. Following the reintroduction of the revised assay on 12th ... Read more >>

The effect of laboratory testing on emergency department length of stay: a multihospital longitudinal study applying a cross-classified random-effect modeling approach.

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

OBJECTIVES:The objective was to examine the relationship between laboratory testing (including test volume and turnaround time [TAT]) and emergency department (ED) length of stay (LOS), using linked patient-level data from four hospitals across 4 years. METHODS:This was a retrospective, multisite cohort study of patients presenting to any one of four ... Read more >>

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 >>

What is the effect of electronic pathology ordering on test re-ordering patterns for paediatric patients?

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

Electronic ordering systems have the potential to enhance the efficient utilisation of pathology services. The aim of this study was to assess the effect of electronic pathology ordering on repeat test ordering for paediatric patients (ages 0 to 18 years) who were in intensive care units (ICUs) and non-ICU wards. ...

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 >>
