Hypothesis

Does UpToDate provide better information retrieval and user satisfaction compared to PubMed Clinical Queries for clinical residents?

Conclusion

Using UpToDate leads to a higher proportion of relevant answers retrieved in less time and greater user satisfaction compared to PubMed Clinical Queries.

Supporting Evidence

  • 76% of questions were answered using UpToDate compared to 43% using PubMed.
  • Median time to answer retrieval was 17 minutes for UpToDate and 29 minutes for PubMed.
  • User satisfaction was significantly higher for UpToDate in terms of accuracy and interaction.

Takeaway

When doctors look for answers, using UpToDate helps them find the right information faster and makes them happier than using PubMed.

Methodology

A crossover randomized controlled trial was conducted with 44 clinical residents who used both UpToDate and PubMed Clinical Queries to answer clinical scenarios.

Potential Biases

Participants may have had varying levels of familiarity with the databases, which could influence results.

Limitations

Participants' native language was Persian, which may have affected retrieval times; limited number of questions and clinical categories were included.

Participant Demographics

44 residents, 63% male, 90% in their first year of residency, mean age 32 years.
