The manual attachment of diagnostic reports to a patient’s medical record is a time consuming process and, combined with the inputting of codes, can often mean you spend more time carrying out administration tasks than caring for your patients. Manual data entry can also compromise patient safety, through the attachment of test results to the incorrect patient medical record.

I3 integration provides a solution to these problems by acting as a link between your GP clinical system and a range of 12 lead ECG, ABPM and spirometry devices.

I3 will retrieve a patient’s details from the EMIS, TPP SystmOne or Vision clinical systems and automatically pass this information to the diagnostic device you want to use, ready to perform your test. Once all the tests have been completed, I3 will then file a PDF report of the test results and any associated coded results directly into the patient’s medical record automatically. This makes your diagnostic testing safer, faster and easier.

“We like the TrueFlow spirometer very much. It is easy to use with clear, easy to understand information on the blows appearing on screen. Excellent visual representation of an effective blow on screen with the balloon... a very useful aid for patients!  Maintenance/cleaning is much easier than our old spirometer which saves time, as does the instant entry on to the Vision patient records. Definitely a good investment and any technical problems are very quickly and efficiently solved by your helpline technicians.  Highly recommended!”

Rachel Young, Lead Practice Nurse, Sandown Health Centre, Isle of Wight

“Our Practice Nurse finds the new spirometer very easy to use - it also Read codes the numerous data automatically back onto the patient record saving her so much time and eliminating any chance of input error and likes the reports she can produce. The support and training have been quick and efficient”

Lisa Fogg Practice Manager, Perranporth Surgery, Cornwall
