Insights
Electronic pathology ordering significantly reduced repeat lab tests for pediatric patients in intensive care units (ICUs) and non-ICU wards. This system helps clinicians avoid unnecessary duplicate testing, improving efficiency.
Area of Science:
- Medical Informatics
- Laboratory Medicine
- Pediatric Healthcare
Background:
- Electronic ordering systems offer potential for optimizing pathology service utilization.
- Assessing the impact of electronic systems on clinical practice is crucial for healthcare improvement.
Purpose of the Study:
- To evaluate the effect of electronic pathology ordering on repeat test rates in pediatric patients (0-18 years).
- To compare repeat ordering patterns between electronic and paper-based systems in intensive care units (ICUs) and general wards.
Main Methods:
- Retrospective analysis of 85,728 pathology tests for 5,073 children before and after electronic ordering implementation.
- Comparison of repeat test rates across different age groups and care settings (ICU vs. non-ICU).
Main Results:
- Electronic ordering significantly lowered repeat test rates for pediatric patients in ICUs.
- Reduced repeat tests within 23 hours were observed for children over one year in non-ICU wards with electronic ordering.
- A consistent decrease in repeat tests within one hour was noted for older children in all wards and younger children in ICUs using electronic systems.
Conclusions:
- Electronic pathology ordering systems, with features like alerts and previous order visibility, effectively reduce unnecessary repeat tests.
- Implementation of electronic systems can enhance efficiency and potentially lower healthcare costs by minimizing redundant laboratory investigations.
Abstract:
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. The dataset described 85,728 pathology tests ordered for 5,073 children before and after the implementation of electronic ordering. This study showed that, for children in ICUs, the repeat test order rate was significantly lower for electronic orders than for paper-based orders. Similarly, the rate of repeat tests ordered within short intervals (up to 23-hours), for children older than one-year in non-ICU wards, was lower for electronic ordering than for paper ordering. The proportion of repeat tests occurring within one-hour of the previous test was consistently lower for tests ordered using electronic ordering than it was for tests ordered using the paper based system for patients older than one-year in all wards and for patients under one-year in ICUs. These results suggest that features of the electronic system, including alerts about previously ordered tests and the availability of information about previous orders, can help clinicians to identify and reduce unnecessary repeat tests.
