Event Description

We received an allegation questioning inr results from a coaguchek xs meter serial number (b)(4) for one patient reportedly bridging with lovenox after a planned medical procedure.The patient¿s regular warfarin dose was 5mg for 5 days and 2.5 mg for 2 days.On (b)(6) 2021, the patient had a pre-scheduled heart ablation procedure.The last inr result from the meter was reportedly 2.0 inr on (b)(6) 2021.On (b)(6) 2021, the patient reportedly had a meter result of 1.1 inr.The patient was reportedly advised by the doctor to start bridging with an injection of lovenox every 12 hours and continue her regular warfarin dose of 5mg for 5 days and 2.5 mg for 2 days.Following this advice, the following results were obtained on the meter: on (b)(6) 2021 1.4 inr 10:44am.On (b)(6) 2021 1.7 inr on her meter at 11:39am.On (b)(6) 2021 patient obtained a 1.6 inr on her meter at 4:40pm.On (b)(6) 2021 the meter batteries were replaced and the date and time were not reset by the user in the meter.During the call, the reporter was instructed on how to set the meter to the correct date and time per product labeling.On (b)(6) 2021 the patient reportedly had a bleed at the ablation site.The patient¿s husband reportedly called the on-call nurse and was told to apply direct pressure for 10 minutes which reportedly stopped the bleeding and no further medical treatment was needed.On (b)(6) 2021 at 3:34 pm, the patient reportedly had an inr result on the meter of 1.8 inr.The patient was reportedly advised by the doctor to stop the lovenox injections and continue with her regular warfarin dose and test again in a couple of days.On (b)(6) 2021, the patient reportedly had an inr result of 2.0 inr from the meter.The patient was reportedly advised to continue the normal warfarin dose and test again in a couple of days.On (b)(6) 2021, the patient reportedly had an inr result of 1.5 inr from the meter.The patient was reportedly advised by the doctor to increase the warfarin dose to 5 mg daily and test again in a couple of days.On (b)(6) 2021, the patient reportedly had an inr result of 1.6 inr from the meter.The patient was reportedly advised to continue the warfarin dose of 5 mg daily.The reported inr results from the meter have been verified in the returned meter memory.The patient¿s therapeutic range was 2.0 - 3.0 and the patient normally tests every 2 weeks.
