The CHADS-BLED Calculator displays percentage risk of adverse event per year, as well as the raw data from the original trials upon which these scores were derived.
It includes the following features:
• Videos by experts discussing various aspects of A. Fib.
• Chapter summaries with key recommendations, tables, and figures
• Tools including: CHADS2/CHADS-VASC score for stroke risk assessment, HAS-BLEED Score for bleed risk assessment, CCS Severity of Atrial Fibrillation (SAF) scale, QT/QTc calculator, renal function calculator (eGFR, CrCl) for drug dosage adjustment.
• An ECG gallery
• Drug tables
• Key references
Note: The default keyboard on certain devices may not contain a comma, which is needed for some tools. If so, please install the default Google Keyboard: https://play.google.com/store/apps/details?id=com.google.android.inputmethod.latin
The calculator helps to stratify patients according to stroke risk and bleeding risk, based on the presence of various risk factors. Stroke risk can be determined using either the CHADS2 score or the CHA2DS2-VASc score – an extension of the CHADS2 scoring system incorporating additional risk factors – while the HAS-BLED score is used to assess bleeding risk.* Creatinine clearance can also be calculated (according to the Cockroft-Gault equation) to measure a patient’s renal function, which is often reduced in the elderly and requires dose adjustment of some drugs that are cleared by the kidneys.
A review of international guidelines for antithrombotic therapy in AF, which are based around stroke risk, is also included, along with directions to further reading in the form of supporting literature.

It is our favorite discussion after all. Our medical cases define our everyday job.
Most of us keep our best cases as a personal file for our records.
Discussing about medical cases is being done till now offline.
Wouldn't be perfect if we had a mobile tool for this?
A mobile based tool where we can discuss our cases and get peer feedback, exchange our ideas, gain visibility over our expertise and meet other doctors with the same interests in a world wide community of doctors?
A mobile based tool where we can search for similar cases like the one that troubles us right now or where we can ask our peers about how they treat their patients with similar problems.
Genetium Cardiology is an open invitation to all doctors to reach out and share their expertise.
An invitation to create a goldmine of knowledge where we, all the experts, are sharing to improve medical practice worldwide and why not, humanity as a whole.
We are always open to your feedback firstname.lastname@example.org
In just ONE SCREEN, essential parameters are entered and displayed the results: the scores of thromboembolic risk (CHADSVASC), haemorrhagic risk (HASBLED) and glomerular filtration rate (Cockcroft-Gault formula). Finally, always in the same screen, are shown the resulting antithrombotic therapies, in adherence to the ESC guidelines.
At the bottom of the screen data are entered:
- age, weight (kg) and serum creatinine (mg/dL) , with keys (+) and (-) sensible to short or long click, for a quick and easy insertion of the values
- check-list of 12 clinical-anamnestic items.
Based on the data entered, the calculated results are automatically displayed in the upper section of the screen:
At the top right are shown the scores CHADSVASC, HASBLED and creatinine clearance calculated by the Cockcroft-Gault formula.
In the upper left shows the resulting therapeutic indications based on ESC guidelines 2012: three "traffic lights" appearing green or red for the three treatment options:
1) no antithrombotic therapy (NONE)
2) vitamin K antagonists (VKA)
3) New Oral Anticoagulants (NOAC).
For Italy we suggest our specific application, "AF Global Calculator (ItalY), based also on AIFA (Agenzia Italiana del Farmaco) restriction for Dabigatran's prescription.
DISCLAIMER : The author assumes no responsibility for use of this application and invites who use it to verify the results provided and adapt them to the clinical context.
The "AF Global Calculator (Europe)", on the Android platform, was developed entirely (drafting of the algorithm, technical development, graphics solutions) by Dr. Francesco Gemelli, Cardiologist in Rome.

This is a simple to use and clean looking depression scoring system produced with permission form Pfizer who hold the copyright. It is aimed at health professionals to use as a consultation tool. There is no decision support, one should use local guidelines. It is one of several new Apps for primary care. If there is sufficient interest then I will develop it further, Suggestions are welcome.
It is suitable for use by general practitioners, community psychiatric nurses, community nurses midwives and trainee doctors or medical students, clinical psychologists and other mental health professionals.
Has support for Spanish French and Norwegian.
This App is the ABCD2 stroke risk assessment score giving the risk of stroke at 2 days and as I am sure you know the score also reflects the relative risk at 90 days. This App is aimed at any medic involved in stroke risk assessment and particularly general practitioners in the UK. It predicts the risk of stroke after a TIA (transient ischaemic (ischemic if American) attack). It is suitable for GPs, registrars, other trainee doctors, community nurses and matrons, and the keen medical student. Deliberately there is no decision support but a couple of links to the research, to whet your apatite.
So this is what you have been waiting for, all your favorite medical scoring systems in one program. But lo! I hear you cry whats so new? Well rather than a boring drop down menu to select from you have them all on a rotating cube for ease of access, simply rotate the cube to the score you want and press the select tile and it will launch.
This app is aimed at medical professionals particularly primary care professionals and includes the following scores.
Qrisk (2013 algorithm only, will update to 2014 when get time), CHAD2DS2_VASc and HAS-BLED scores, ABCD2, Wells, Epworth, and a glycated Hb converter with the WHO recommended diagnostic thresholds and pitfalls to diagnosis all via the in app menu system.
These scores are variously used in diabetes mellitus diagnosis, Atrial fibrillation stroke reduction assessments sleep apnoea and snoring assessments, prevention of heart attach myocardial infarction and cerebrovascular accidents as well as deep vein thrombosis (DVT) assessment and pulmonary embolus (PE) assessment via the combined Wells score, please read the in app information regarding this score. They may also help with QoF assesments (Quality and outcomes framework)
This is the free version look out for the paid version (coming soon) that will allow you to load your own photographs for a more personal experience out there when crafting your diagnoses!
Cardiac 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.
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.
This converts glycosylated haemoglobin (Hb or hemoglobin if you are American) (HbA1c or A1C) from the old percentage (NGSP)units to the new mmol/mol (IFCC)units and vice versa. It allows entry of a value and the App will convert it accordingly.
Suitable for anyone involved in diabetes care be they doctors or nurses, community or hospital medics, medical students, dietitians, general practitioners, practice nurses, diabetes nurse specialists.
The App also has the diagnostic criteria for diabetes using HbA1c from the World Health Organisation (WHO), as well as some of the pitfalls of diagnosis as outlined by the referenced research. These three papers are the start of an intriguing argument about the merits of this diagnostic process. I think Farmer's subheading "Be aware of clinical circumstances in which results may mislead" sums it up nicely.
The diagnosis of diabetes section is accessed through the 'menu' button.
Patients need not worry themselves with this App.
Version 1.2 deals with a rounding up problem which was giving slightly non standard results, much to users chagrin, this version will only give expected results, please take time to rate it if you believe its improved from the 1 ratings.
The App also now incorporates its own key pad for a new feel and better landscape functionality.
This App contains the two Wells scores that aid the diagnosis of low risk deep vein thrombosis (DVT) and pulmonary embolus (PE). It is for use by suitably trained medics and as always with these scores they are only an aid and should always be used in conjunction with local guidelines.
The two scores operate independently of one another, where the questions overlap with differences these are highlighted. The only point of note here is that the question “Clinical signs and symptoms of DVT (minimum of leg swelling and pain with palpation of the deep veins)” in the PE score and worth three points is replaced by the three questions relating to pain and swelling within the original DVT score. A tick on the question relating to tenderness along the deep veins and one or both of the questions relating to swelling (over 3cm... or of the whole leg) will allocate the three points correctly to the PE score. Of course if you are scoring a DVT then the score accumulates as you might expect.
If the text is too small simply tap it to get a larger view then tap again or press the 'back' button to dismiss. The references and information about the App are available via the menu button. Tapping the “Use this because..” will bring up the two level score outcomes. Suggestions are welcome. Suitable for general practitioners, community nurses, specialist nurses, registrars, other junior doctors and medical students.
1.2.2 Changed the layout a little so than now the NICE guidance is present at the bottom of the screen for ease of reference. Just scroll down to take a look.
This App is designed for suitably qualified medical professionals when assessing day time somnolence. Currently it provides a score only, if there is sufficient interest then I will add some decision support, for now consult your local guidelines. It is aimed mainly at primary care, and is the first batch of several scoring support tools. This is a simple tool, using minimal storage space, to be used within the consultation. Suitable for general practitioners, community nurses, medical students and registrars for example.
