Intelligent INR Testing with the Siemens Xprecia Stride I've been extremely impressed with its feel, functionality, consideration of the user and patient aswell as governance and audit Review by Dr Raj Thakkar BSc (Hons) MBBS MRCGP MRCP (UK)

There is little question that near patient testing for INR brings with it both convenience and safety for the patient, and improves efficiency across the health economy.

As such the business case for adopting a new service delivery model based on near patient testing is robust for a practice or community provider keen to adopt an AQP or similar contract with their CCG, or indeed an acute provider wanting to improve efficiencies. Moreover, developing such a system is a QIPP, particularly when embedded in an AF opportunistic screening and effective anticoagulation programme.

The issue really boils down to which near patient testing machine to use...

For me, there are several criteria to consider when choosing a unit. Perhaps the first is a little indulgent but it needs to look the part and there is no question this machine looks very classy. It has a robust modern feel and is clearly designed with ergonomics and ease of use in mind.

The kit comes with computer software and a cable and a number of coloured caps, but no case just yet. The unit itself is powered by three AA batteries and it rather cleverly won't function if there isn't sufficient power for a test, avoiding embarrassment and frustration. It powers up in no time at all, presenting a responsive colour touch sensitive screen.

When first switched on the unit requests current time and date entry after which the home screen appears. Four icons then appear, namely test, settings, previous test recall and quality control.

Settings go far beyond date, time, volume, brightness and language. There are some really useful and rather clever tools such as adding individual administrators, each with their own unique pin or bar code ID which is great for governance and audit.

Testing is a highly efficient and easy process which doesn't necessarily require entering patient ID. It takes seconds to prepare the machine for testing. Once the test icon is pressed from the home screen, it requests the user to scan a fresh test strip. The infrared scanner is actually based in the handle of the unit which is highly impressive and eliminates the risk of using a strip from the wrong batch.

If the strip is from a new batch, the Siemens Stride™ will ask for vial of strips to be scanned too and the calibration is automatic.

Once the strip is inserted, it is warmed prior to a countdown, during which time the patients finger is lanced and a sample tested. Less blood is required than atypical blood glucose kit. With practice it takes less than four minutes from turning the machine on to knowing a patient's INR. An ejection button is then pressed for a no-touch clean discharge. The coloured caps can be taken off to clean and the machine can even track who and when it was cleaned, which will certainly keep the CQC happy.

This is clearly an intelligent and competitively priced system. A lot of thought has gone into its design and I've been extremely impressed with its feel, functionality, consideration of the user and patient as well as governance and audit. It really is impressive and I can't imagine many disappointments.
