DescriptionCardiac and cerebral risk assessment tool. (CCRAT)
At last a version of Qrisk for android! This is the primary prevention risk scoring system based on the desktop version of Qrisk2-2013 (Copyright © 2008-13 ClinRisk Ltd. ALL RIGHTS RESERVED).
It works out the risk of having a myocardial infarction or stroke, it gives the 1 to 10 year risk as well as the Qriskage (QRISKage™ is © 2010-13 ClinRisk Ltd). This scoring system has greater validity than the modified Framingham score, please see in in App references.
This App uses the same algorithm as the original Qrisk desktop version (and their i phone version,) it is produced using the code available as open source software which implements the QRISK2®-2012 scores, released under the GNU Lesser General Public Licence, version 3. Please take time to read this information in the 'about' menu.
It will therefore faithfully reproduce the same scores as the original.
Unfortunately the Townsend to Postcode table that the desk top version uses to quantify deprivation is not accessible to mobiles (this goes for the ClinRisk ltd's i phone version too) and so I have used a slider bar where one can estimate deprivation. It can be turned off if desired. Click the 'null' tick box to remove this. Market towns are going to lie from the mid line to the upper fifth, and inner city tower blocks be in the lower fifth for example. If the 'null' value is set then deprivation plays no part in the assessment, this means that the more deprived you are the score will be underestimated by a few percent, and likewise over estimate your risk , again by a few percentage points, if the patient is more privileged.
This is intended for use by all health care professionals involved in assessing cardiovascular and cerebrovascular risk. It is a primary prevention tool only. It will be of particular use to general practitioners when completing the QoF (Quality and Outcomes Framework) when assessing CVD risk, whichever clinical system be it systemOne or Emis, as the data can be entered whilst viewing other screens. It is not ideal for patients to use this to assess their own risk of heart attack nor stroke.
For UK General Practitioners I have added a 'Qof Correction' button, this runs the score again but sets the BP to 150/90 for the patients aged 80 and more and to 140/90 for those 79 years of age and less. The reason being that there is a reasonable opinion that lowering a 78 year old's BP to 140/90 or less is not always a good idea. This button thus calculates the corrected risk of heart attack or stroke if their BP were at the lower level. The idea being it provides another source of evidence that exception reporting is perhaps the best option.
It is validated for use in the United Kingdom. However the algorithm is said to have some use internationally and can act as a guide in other westernized societies.
It should be noted that this App is a tool and all decisions about a patient's health are the responsibility of the medical practitioner making the decision. I cannot accept any responsibility for its use or misuse.
