INR self-testing – why the need?

Many patients who attend the clinic continue to suffer from poor INR control, increasing their risk of a stroke

Many warfarin clinics are operating at near capacity and are near financial loss

Regular clinic visits can be inconvenient and costly, having unnecessary implications on patient’s day to day lives

Our solution? A digitally enabled INR self-testing care pathway which enables warfarin patients to monitor their health from the comfort and convenience of their own home

The Health Call INR self-testing service enables patients to self-test their international normalised ratio (INR) from their own homes, meaning they do not have to attend the warfarin clinic every few weeks.

The INR self-testing service provides patients with a Roche self-monitoring device. Patients then provide their care team with their readings using a method which suits them, either through an automated phone call or an on-line portal.

Any irregular readings or adverse answers alerts the warfarin clinic so contact can be made with the patient. The INR and warfarin data is directly sent to the patient’s clinic where, using anticoagulation software, the next warfarin dose and date of the next INR test is calculated. The patient then receives a second automated phone call at a pre-agreed time. If readings are normal, the automated phone calls continue. In the case of the online portal, email reminders continue as normal.

The Health Call INR self-testing service has transformed the lives of patients across the UK. So much so, we believe INR self-testing should be available to all patients on warfarin.

Our clinical studies consistently show a marked reduction in adverse events for those on the INR self-testing service compared to those who are not. In a pilot of this service time in therapeutic range (TTR) increased on average by 20 percentage points.
