Patient Self-Testing with DAWN AC

As patient self-testing continues to grow, 4S DAWN have been working to help customers facilitate the growth in this cohort of their patient population.

For stable patients on long-term anticoagulation therapy, the time, cost and inconvenience of attending an anticoagulation clinic on a regular basis can be a burden that affects both the patients’ work and lifestyle.

Self-testing offers the patient flexibility and removes these barriers, providing a sense of control and empowering them to take an active role in their care, often with improved results.

“The evidence shows that a greater use of self-mornitoring offers clinical and patient benefits and, overtime, is likely to result in reductions in heart attacks and strokes caused by blood clots’

Professor Carole Longson, NICE Health Technology Evaluation Centre Director

 An increase in your patient self-testing population can also provide benefits to your anticoagulation clinic:

  • Improved outcomes
    • Patients actively engaged in their care and regularly testing, helping to maintain therapeutic range
  • Reduced burden on anticoagulation clinics with fewer clinic appointments required
    • Since March 2013, the patient self-testing service at County Durham and Darlington Foundation Trust has delivered a saving of 21,000 clinic appointments.
  • Improved quality of life for your patients
    • Remove the inconvenience of attending regular clinic appointments
  • Increased efficiency
    • More resource available to focus on unstable patients

There are different approaches to building and improving the monitoring of your patient self-testing population using DAWN AC:

DAWN INR Capture

The DAWN INR Capture tool is a quick and easy, mobile/tablet friendly way for INR self-testers to capture INR results and supporting information and send it to specialist anticoagulation therapy management systems such as DAWN AC or electronic medical records.

The INR results can be imported straight into your DAWN AC patient record in the same way INR results can be imported from your laboratory system.

DAWN INR Capture is compatible for use with PC, laptop, tablet and phone.

Digital Self-Monitoring Service

County Durham and Darlington Foundation Trust (CDDFT) have been working with 4S DAWN and InHealthCare to roll out an automated self-monitoring service which enables patient self-testers to take a fingerprick blood sample and communicate their INR back to the clinic using a communication channel of their choice e.g. phonecall or online.

The information is integrated directly into the DAWN AC patient record where a new dose and next test date are calculated by the system and communicated back to the patient, again via their communication channel of choice.

In the last three years, CDDFT’s self-monitoring service has saved 21,000 clinic appointments, equivalent to a £125,860 saving for the Trust in staff time and consumables.

In a recent 24 month follow-up study from County Durham and Darlington Foundation Trust, over 70% of patients on the self-testing service improved their Time in Therapeutic Range by 20%

Patient Self-Testing via Text Message

St James’s Hospital in Dublin introduced a successful patient self-testing programme that led to the development of a text message service that enabled INR results sent by patients via text message to be transmitted straight into the DAWN AC patient record and a text message returned to the patient with their dosing instructions.

Monthly audits of the DAWN AC system showed that patient self-testers had a higher percentage Time in Therapeutic Range than those who attended clinic.

NICE Guidance includes the following trial data in relation to self-monitoring

In 15 out of 18 trials, time in therapeutic range was higher in self-monitoring patients compared with those in standard care and in 5 of those trials, the difference between the two groups was statistically significant.

Of 12 trials that reported INR values in therapeutic range, ten of the trials reported higher proportions of INR values in therapeutic range or larger proportions of participants in therapeutic range for self-monitoring than for standard care.

Of 21 trials reporting major and minor thromboembolic events, self-monitoring showed a statistically significant reduction in the risk of thromboembolic events compared with standard care. This risk reduction further increased when only major thromboembolic events were considered.
