How it Works

Once registered, users have access to many functions and tools that support evaluation and improve productivity.

  • Access options:
    • Website at; most of our registered clients prefer this user interface.
    • Mobile - iOS app in the App Store for iPhones and iPads; same content as on the website; layout and navigation is adjusted to screen size.
    • Android app in Google Play for smartphones and tablets; same content as on the website; layout and navigation is adjusted to screen size.
    • API access for interoperability and bulk processing. See below Point 18 for more options of institutional users.
    • SDK for developers with sufficient API calls to create a third party application.
    Operating the apps requires an internet connection. Inputs are not cached and the analytics and calculators do not work without an internet connection.
  • Registration: registered users have access to selected functions and up to 100 calculations and documentations.
  • Subscriptions(coming soon): subscribers have unlimited access to all calculators, documentation, and premium tools for personalization. Currently all registered users and have access to all content and personalization options. Institutional subscriptions from university libraries and institutions will provide full access to all their members.
  • Searching for calculators:
    • Screen and browse to identify suitable decision analytics by medical condition, keywords, references or ICD-10 codes.
    • Algorithms with calculators are highlighted by a blue dot in front of the title. Analytics with only documentation and references do not have the blue dot.
    • Select from our Packs on medical specialties and give you access to all analytics along the stages of diagnosis and treatment.
    • Refine your initial search results by specialty and objective using the additional selections on the left of the screening results.

      You can choose from the following objectives and sub-objectives:




      Patient Concerns

      You can choose from the following specialties and sub-specialties, which are grouped according to the AMA Physician Specialty codes:

      Allergy, Immunology



      Endocrinology, Diabetes, Metabolism

      Emergency Medicine

      Family, General Practice


      Internal Medicine

      Medical Genetics

      Neurological Surgery


      Obstetrics, Gynecology







      Physical Medicine and Rehabilitation

      Plastic Surgery

      Preventive Medicine






      Each calculator opens in a new tab so you can keep your search results. There are further options for storing your selected calculators as described in more detail below.

  • Selecting the right analytics

    As a professional in clinical evaluation and analysis, you can choose from our large number of medical calculators and clinical scores. However, it can only be your responsibility to select the right analytics to support you in the specific case under review. We assist you in this selection by providing several user-friendly searching and browsing options, as well as collections by specialty.

    Screening and browsing allows you to identify suitable decision analytics by medical condition, keywords, references or ICD-10 codes.


    You can select to screen all our 4,000 calculators or select to screen all 22,000 algorithm descriptions. Automated analytics show a blue dot in front of the title.

    Refine your initial search results by specialty and objective of the additional selections on the left of the listing.


    • By specialty: our list of specialties and sub-specialties shows when clicking on the Specialty button.
    • ICD-10 code: list of ICD-10 codes shows when clicking on the button.
    • Medal Packs: Select from our Packs on medical specialties and give you access to all analytics along the stages of diagnosis and treatment. This is a systematically developed professional compilation to assist you with patient decisions for specific medical conditions. We are constantly adding new Specialty Packs to our platform.
    • Guidelines: These provide analytics based on an official medical guideline of a medical/scientific society or workgroup and follows the medical workflow, from diagnosis to prognosis, treatment all the way to follow-up.
  • Top Algorithms – on the second line of tabs at the top of the website you see the Top analytics used by our audience. Hovering over the name shows a brief description of the purpose.
  • Calculator execution - Each calculator page has three sections:

    Title section: this is where you can see relevant information about the application and the condition under review.

    Evaluation section: here is the input data of the patient that is required to compute the results of the predictive algorithm. Inputs are restricted to realistic value ranges. If your inputs are extreme, you get a warning message. If your inputs are out of range, the calculation will not proceed.

    Results section: the screen moves automatically to the Results section when the evaluation is submitted and all inputs are correct. If the Results do not show, please check your inputs and observe the warning messages.

    Each algorithm includes a short description explaining its purpose. You execute an algorithm by entering your relevant evaluations into the data interface and submit it to obtain the results. Input values are range-checked and warning messages displayed if your inputs are outside realistic ranges. Calculators do not run if inputs are outside the defined range. The analytics require an internet connection. Data inputs are not cached. If you observe an issue on one of the analytics, we welcome your feedback. We will respond and fix any problems immediately.

  • Interpretation and Description – this section provides you with background on the scientific studies behind the analytics. All studies and the original papers have been peer-reviewed. Our team of physicians and seasoned software engineers with healthcare experience have rigorously tested our calculators. If you observe an issue on one of the analytics, we welcome your feedback. We will respond and fix any problems immediately.
  • Your individual needs: you can save the results, store the algorithm as a favorite, create individualized paths of series of analytics, print, email, save and forward any calculator to an email address or explore our suggested algorithms for additional evaluations of the situation under review.
  • References and PubMed IDs – here you have all the references and a direct link to the abstract in the US National Library of Medicine at NCBI.
  • ICD-10 codes – we show you the ICD-10 codes and a brief explanation for each calculator. Our Links tab gives you access to the CMS and WHO websites with detailed explanation of all ICD-9 and ICD-10 codes.
  • Next Steps in Evaluation – you may be interested in additional analytics related to the specific calculator just used. The suggested analytics are categorized by clinical objective. These related calculators were selected by medical practitioners to suggest similar analytics that could be of interest for your evaluation. Hovering over the name shows you a brief description.
  • Testing and Verification – We make every effort to provide high quality validated software and analytics. Reliability and usability are of great importance to us. We have taken particular care in developing, verifying, testing, and maintaining our calculators. We are following established policies for technical and medical review on all our analytics.
