Description of intervention(s) / exposure
patients requiring international normalised ratio (INR) as part of their assessment have venepuncture performed and less than one ml of the venepeuncture drawn blood is simultaneously used for the point of care (POC) INR test and a comparison of the results is then carried out

Outcomes
Primary outcome [1] 5709 0
90% agreement between the Point of Care (POC) and laboratory International Normalised ratio (INR) where agreement is defined as the POC result within 15% of the laboratory result
Timepoint [1] 5709 0
both investigations use the same blood drawn via venepuncture. The laboratory result when available is then compared to the result from the point of care machine which is done as soon as possible after venepuncture
Secondary outcome [1] 241868 0
assessment of clinical utility

Summary
Brief summary
Point of Care (POC)technology as the potential to expediate decision making and therefore benedit patient care and flow throught the Emergency Department. POC International Normalised Ratio (INR) is in common use in the community for monitoring warfarin therapy use. If found to be accurate as a marker of coagulopathy for emergency patients would potentially be a useful addition to tests available to the Emergency Physician
