Redesigning the process in the ambulatory emergency care at James Paget University Hospital

A study of emergency admissions in England found that over a quarter of admissions did not require an overnight stay (length of stay [LoS] of zero).1 This suggests that many emergency patients could benefit from ambulatory emergency care (AEC)1 by having a systematic approach to process redesign. This entails immediate access to urgent care that would usually require the resources and expertise available in an acute hospital.2

Integrated POCT devices, such as the i-STAT System™, are likely to offer more options for managing patients in an AEC setting.

POCT fulfilled over 85% of patient diagnostic needs in the AEC setting.3

The i-STAT System, in particular was used for a variety of common tests, with the following cartridges used most widely:3
  • CHEM8+ to test blood electrolytes, basic hematology parameters and TCO2
  • CG4+ to test lactate and blood gases
  • PT/INR to test prothrombin time (a measure of blood coagulation)
