Mobile Apps & Resources: MedHF

To keep you updated on the go, our ‘app of the month’ highlights one free informational app every month!

Librarian reviewers consider the audience and purpose of the apps, as well as highlighting additional features:
  • In the ‘Evidence’ section, we assess how easily an app user can identify the app’s currency and support from the evidence
  • In the ‘Usability’ section, we assess the organization of information and other usability factors that may contribute to user experience

Our complete grading criteria for evidence and usability are embedded in the review.

Please note that the reviewers are not healthcare professionals, and so cannot appraise the quality of any recommendations within the app. The reviews are not endorsements.

Stated Purpose

“[S]upports healthcare professionals in the initiation, titration, assessment and monitoring of the 4 drug classes commonly used to treat heart failure: ACEIs/ARBs, Beta-Blockers, Diuretics, Aldosterone Antagonists. Developed by Alberta Health Services in collaboration with the CCS, it guides users through evidence-based algorithms and recommends appropriate actions and considerations based on 2011 CCS Heart Failure Guidelines.” (Source: Canadian Cardiovascular Society (n.d.)

Part 1: Editorial committee, content updates, and evidence grading

Entries are not dated. Author names are not provided. There is information about the app in the App Store or Google Play, but not in the app. Some contents have a reference section where the reference is graded. The grading is explained.

Part 2: Source and authorship information for 3 entries

There are three major categories. Evidence syntheses in two of them – Medical First Response Protocols and Critical Care MCPs (v2.0) don’t have citations. Syntheses in Medical Control Protocols (v2.3) have citation lists, but not in text citations.

No author information with any of the entries.

Organization of information

Content is grouped into 4 sections:

- General approach (Algorithm for prevention and treatment of clinically stable heart failure), provided in a single- screen overview
- Drug Information is divided into 4 major drug types: ACEIS/ARBS, Beta-blockers, Diuretics, and Aldosterone Antagonists. After selecting a drug type, the user selects information on initiation, titration, or monitoring
- Dosing information for each drug type, including initial dose, target dose, and dosage forms, provided in a single-screen overview
- Information, linking out to references (requiring Internet connection); also includes pearls and acronyms (available offline)


Drug information is structured to allow quick, case-specific navigation: the user proceeds down a customized pathway to find specific information
General approach and Dosing tabs provide a one- look overview of information
Some screens will ask users yes/no questions about patients, to guide initiation, titration, or monitoring
