Most diagnostic decision support systems fail to meet user needs. This study found family physicians primarily sought general information, not specific diagnostic support, for common conditions.

Area of Science:

  • Medical Informatics
  • Clinical Decision Support
  • Family Medicine Research

Background:

  • Diagnostic decision support systems (DDSS) are frequently developed without user needs assessment.
  • Understanding clinician information requirements is crucial for effective DDSS design.
  • Family physicians' information needs remain an area requiring further investigation.

Purpose of the Study:

  • To assess the specific information needs of clinicians, particularly family physicians.
  • To determine the demand for diagnostic decision support among primary care physicians.
  • To identify the types of clinical information and content areas most frequently requested.

Main Methods:

  • Analysis of a series of questions submitted by family physicians to an information service.

  • Categorization of questions to identify diagnostic support needs, information types, and content areas.
  • Comparison of question frequency with the prevalence of conditions in ambulatory care settings.

    • Main Results:

    • Less than half of the submitted questions were related to diagnosis.
    • The majority of diagnostic questions were requests for general information on conditions, not specific diagnostic support.
    • Infrequent diagnostic questions were identified for conditions commonly encountered in ambulatory care.

    Conclusions:

    • Current diagnostic decision support systems may not align with the actual information needs of family physicians.
    • Physicians' primary need appears to be for general information rather than complex diagnostic algorithms.
    • Future DDSS development should consider the practical information requirements and common conditions faced by primary care practitioners.
