This study developed metrics to assess search tools. The eSearcher tool resulted in longer search times but similar accuracy and confidence compared to excluding it.
Area of Science:
- Medical informatics
- Information retrieval
- Health sciences education
Background:
- Assessing information search tool effectiveness is crucial for evidence-based practice.
- Developing standardized metrics aids in evaluating search tool performance.
Purpose of the Study:
- To develop an evidence-based method and metrics for assessing information search tools.
- To evaluate the performance of a specific search tool (eSearcher) in a pilot study.
Main Methods:
- A pilot study compared graduate nursing students and resident physicians using a familiar search tool (eSearcher) versus excluding it.
- Participants searched for clinical guidelines, with measurements including search time, accuracy score, and confidence score.
Main Results:
- The intervention group using eSearcher had significantly longer search times compared to the comparison group.
- Accuracy and confidence scores were lower in the intervention group but not statistically significant.
Conclusions:
- The study provided insights into the performance and user experience of the eSearcher tool.
- The developed evidence-based methods can be used to evaluate other search tools and inform purchasing decisions.
