No specialty specified
According to the app description: “…physicians, physician assistants, nurse practitioners, pharmacists, and medical students.” Anyone with legal permissions to assess patients could use it.
Part 1: Editorial committee, content updates, and evidence grading
Editorial committee information for MDCalc is listed on the app’s website, but is not available in app. However, all committee members appear to be affiliated with reputable institutions or organizations. While the app is updated frequently based on version history, entries are not individually dated so it is unclear if or when content is reviewed. Evidence grading is not applicable to MDCalc, although links to relevant validation studies are provided.
Part 2: Source and authorship information for 3 entries
An evidence section does appear to be included for each calculator/scale/score that provides formula details and other information needed to explain and appraise the tool, although some entries are more flushed out than others. Supporting literature is also provided as well as information on the calculator/scale/score’s actual creator or inventor. However, no information is listed on who created the entry or wrote the content. An assumption can made members of the editorial board were involved, but this is unclear.
Organization of information
The app provides several options to access and organize content. When browsing, there are 4 main tabs: “Favorites”, “Recent”, “My Specialty”, and “All”. The “All” tab lists all calculators organized alphabetically. The other tabs are for quick access to frequently used or potentially relevant materials. These tabs are populated based on user input. Filtering of content based on type (Diagnosis, Rule Out, Prognosis, Formula, Treatment, Algorithm) is also available, however, one most actually use or click on the search box to access these advanced filters. Search results can also be filtered based on “Disease” or “Complaint”.
The app is straightforward and easy to navigate. Some confusion may stem from trying to access the filter options when using the search function, but this does not impede actually accessing or finding content.
Internet connection required for use: Partial; Access to the internet is needed to view linked articles within the evidence sections. It is not necessary for using the calculators/clinical decision support tools or other parts of the app.
Text search field: Yes;
Browsable content: Yes; The app includes a sophisticated browsable search, where users can narrow by six different categories (Diagnosis, Rule Out, Prognosis, Formula, Treatment, Algorithm) and based on “Disease” or Complaint”.
Pop-up advertisements: Yes; The app does include advertisements for MDGuidelines and MDPearlPulse, which link to the MDCalc website outside of the app. While these ads are for content related to and produced as part of MDCalc, the advertisement itself does not appear to show any correlation to the actual content or calculator being accessed. For example, an ad for Guidelines “Renal Mass: Localized Renal Cancer” popped up on the BMI & BSA calculator. Thus, the reviewers would consider these links as advertisements as opposed to an additional feature.
