Peri-procedural management of warfarin reflects an intricate balance between the restoration of haemostasis and appropriate thromboprophylaxis. This prospective single-arm study assessed the safety and efficacy of a convenient schedule, incorporating low-dose intravenous vitamin K (vitK(IV) ) for short-term warfarin reversal prior to elective surgery, as well as vitK-dependent factor levels (vitK-Factors) and International Normalized Ratio (INR) pre- and post-vitK(IV) .

Methods: The accuracy and ease of use of the recently marketed CoaguChek XS portable INR monitor was evaluated in 17 patients involved in a trial of warfarin home monitoring. INR results from the monitor were compared with those from the laboratory method.
Objective: To compare the accuracy and clinical usefulness of the near-patient testing CoaguChek S INR monitor in rural medical practice. DESIGN, SETTING AND MAIN OUTCOME MEASURES: General practices were identified through Australian university departments of rural health.
