Patient Care Alterations After Point-of-Care Laboratory Testing During Critical Care Transport

Research on point-of-care testing in non-hospital settings remains limited. Prior studies have shown that rapid diagnostic tools can influence clinical decisions in emergency departments. However, few have focused on transport environments. Established knowledge includes the benefits of faster test results in acute care. No prior work had resolved how POCT affects care during transport. This gap motivated the need for transport-specific data. The lack of transport-based evidence creates uncertainty about POCT's role in this setting. This study addresses that uncertainty by examining care changes during transport.

The study aimed to evaluate how point-of-care testing affects patient care during critical care transport. Researchers focused on care alterations linked to POCT results. They sought to identify which conditions most commonly led to care changes. The motivation came from limited transport-specific POCT research. The goal was to provide data on POCT's impact in this unique setting. Researchers wanted to quantify how often care changed after POCT. They also aimed to compare care changes across diagnoses. This work fills a gap in the transport medicine literature.

The study used a retrospective design with transport records from October 2013 to September 2015. Institutional review board approval was obtained for the data review. A total of 11,454 transports were analyzed during the study period. Researchers identified 632 patients who received POCT during transport. They reviewed medical records for any care changes after POCT. The analysis focused on specific diagnoses and care modifications. Researchers categorized changes by type and diagnosis. The study used descriptive statistics to summarize findings.

POCT led to care changes in 38.6% of patients who received testing. The most common changes were ventilator adjustments and electrolyte management. Unit bed upgrades occurred in 7.1% of cases after POCT. Post-cardiac arrest patients had the highest rate of care changes at 64.7%. Sepsis and diabetic ketoacidosis also showed significant care modifications. Pneumonia patients experienced changes in nearly half of cases. Researchers found no single condition dominated all care changes. The results suggest POCT influences transport decisions for multiple acute conditions.

The study found that POCT can lead to care changes during critical transport. The authors suggest that testing may influence ventilator and electrolyte management. They propose that transport teams may alter care based on POCT results. The findings indicate that post-arrest patients may benefit most from POCT. Sepsis and diabetic ketoacidosis also showed notable care modifications. Researchers suggest POCT may support better decision-making in transport settings. The study highlights the potential role of POCT in transport medicine. These results may help guide future research on transport-based diagnostics.
