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 EDs(More)
BACKGROUND It is expected that health information technology (HIT) will deliver a safer, more efficient and effective health care system. The aim of this study was to undertake a qualitative and video-ethnographic examination of the impact of information technologies on work processes in the reception area of a Microbiology Department, to ascertain what(More)
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(More)
OBJECTIVE Manual data-entry of handwritten laboratory test requests into electronic information systems has implications for data accuracy. This study sought to identify the types and number of errors occurring for handwritten serology test requests received from outpatient clinics. METHODS A 15-day audit at a serology laboratory in Sydney, Australia,(More)
The aim of this study was to examine the impact of the Electronic Medical Record (EMR) on the quality of laboratory test orders made by clinicians. The study assessed the type and frequency of pre-analytical laboratory test order errors that were associated with the EMR across three hospitals and one pathology service. This involved a retrospective audit of(More)
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(More)
Electronic ordering systems have the potential to enhance the effective and efficient utilisation of pathology services. This study examined the influence of electronic ordering of pathology tests in four emergency departments on data entry times, a contributing factor to test turnaround time using failure time analysis. Data relating to tests ordered for(More)
BACKGROUND 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(More)
