Purpose of App Review

  • To determine the usefulness of a PubMed searching app.


There are several apps out there for searching the PubMed interface on your mobile device. Some of these apps are developed out of the private sector while others come from government agencies.

PubMed4Hh (PubMed for Handhelds) is developed by the National Library of Medicine (NLM) and is freely available for download.

PubMed4Hh is a popular PubMed mobile resource, though some other resources do a better job of providing a fluid and more familiar interface for searching the database.

Check out the comprehensive evaluation of several PubMed apps for iOS, many of which are now available for Android. Interestingly, some of the free PubMed apps, like PubMed4Hh, offers a slick interface and design.

User Interface

PubMed4Hh’s interface is more of a directory than a functional system. It points users to one of four mobile websites for searching PubMed and NLM data.

The resources are as follows:

  • PICO Search
  • Consensus Abstracts
  • BabelMeSH

PICO Search is a resource for finding references on a topic by posing a clinical question using the PICO format (Population, Intervention, Comparison, Outcome). Asking a question using these components yields a more precise list of results.

Consensus Abstracts points to a page with links to both the PICO site and the askMEDLINE site. I’m not sure why this exists since both PICO and askMEDLINE buttons are on the app home screen.

askMEDLINE allows users to search MEDLINE/PubMed content using free-text, natural language processing. This means there is no need for Boolean operators to perform an efficient search. askMEDLINE takes a Google-esque approach to searching.

BabelMeSH is an interface for searching PubMed using Medical Subject Headings (MeSH) controlled vocabulary to yield more targeted search results on your topic. Using controlled terminologies is beneficial, especially when keyword searching is falling short or lacking in substantial retrieval.


consensus abstracts
