Comparing the accuracy of point-of-care with laboratory (capillary, venous, and arterial) blood glucose levels in critically ill patients with and without shock. | LitMetric

AI Article Synopsis

  • The study aimed to compare the accuracy of point-of-care testing (POCT) for capillary blood samples with traditional laboratory tests using venous/arterial samples in critically ill patients.
  • Data was collected from 268 patients, showing that POCT results were generally consistent with lab findings, with no significant differences noted in most glucose measurements.
  • The findings suggest that while POCT is slightly less accurate than laboratory analysis, it can still be used reliably for critically ill patients, regardless of their shock status.

Article Abstract

Objectives: To compare the accuracy of point-of-care capillary and venous/arterial samples to laboratory testing of venous/arterial samples in critically sick shocked and non-shocked patients. This is a prospective case-control study including capillary, venous, and arterial blood samples from 268 critically ill patients. The King Fahd Military Medical Complex in Dhahran, Saudi Arabia, was the site of this investigation.

Results: We were able to obtain data on 268 patients for this investigation. POCT and lab findings of venous and central blood did not differ significantly (P = 0.389 and 0.208), while POCT indicated somewhat higher results with venous glucose concentrations of 10.18 and 10.05 (POCT and lab tests respectively) and 9.18 and 9.54 (POCT and lab tests respectively). In addition, the mean differences between POC and laboratory analyses of venous, arterial, and central glucose were 0.13, - 1.75, and - 0.36 mmol/L for venous, arterial, and central glucose, respectively. Except for arterial blood glucose, we did not observe a significant difference between POCT and routine laboratory analysis of glucose concentrations in critically ill patients. Compared to laboratory blood analysis, the use of POCT is marginally accurate, with no difference between shocked and non-shocked patients.
