How to keep up with the medical literature: IV. Using the literature to solve clinical problems

Area of Science:

• Medical Informatics
• Information Science
• Clinical Research

Background:

• Effective clinical problem-solving relies on rapid access to current evidence.
• Traditional information retrieval methods may not meet the speed and comprehensiveness required.
• Modern information skills and services are crucial for healthcare professionals.

Purpose of the Study:

• To compare the utility of various information sources for locating relevant journal literature.
• To evaluate the efficiency and speed of different search methods in addressing clinical problems.
• To identify optimal strategies for evidence-based practice in a hospital setting.

Main Methods:

• A comparative analysis of information retrieval tools was conducted.
• Sources evaluated included textbooks, personal reprints, expert clinicians, journal issues, library collections, Index Medicus, and MEDLINE.
• The utility was assessed using the clinical problem of acquired immunodeficiency syndrome (AIDS) risk management in hospital personnel.

Main Results:

• Index Medicus and MEDLINE were identified as the most effective sources for up-to-date articles.
• MEDLINE computer searching proved to be three times faster than other methods evaluated.
• Textbooks and personal collections were less effective for rapidly accessing current research.

Conclusions:

• Computerized searching, specifically MEDLINE, offers a significant speed advantage for clinical evidence retrieval.
• Integrating modern information services enhances the ability to solve clinical problems efficiently.
• Healthcare professionals should leverage tools like MEDLINE for timely access to the best available evidence.
