Area of Science:

  • Medical Informatics
  • Health Services Research
  • Clinical Decision Support

Background:

  • Historical clinical information is crucial for comprehensive patient care.
  • Understanding the utilization patterns of older data is essential for optimizing electronic health records (EHRs).
  • Ambulatory care settings generate significant volumes of historical patient data.

Purpose of the Study:

  • To quantify the frequency and patterns of historical laboratory data use in ambulatory care.
  • To assess the perceived value of historical clinical information in decision-making.
  • To analyze the integration of historical data into provider workflows.

Main Methods:

  • Observational study of 87 providers in a multispecialty group practice.
  • One-month data collection period focusing on historical laboratory data requests.
  • Provider surveys to gauge the perceived benefits of historical data.

Main Results:

  • 38% of providers accessed historical laboratory data for clinical decision-making.
  • Requests for historical data occurred for 19% of patients during the observation period.
  • Historical data use constituted 4% of provider-initiated system transactions (328/month).

Conclusions:

  • Historical clinical information, particularly laboratory data, is frequently utilized by ambulatory care providers.
  • The use of data older than one year supports clinical decision-making processes.
  • Integrating and accessing historical data is a relevant component of modern healthcare information systems.
