Hospitals can safely discard inactive patient radiographs older than 10 years. This reduces storage while minimizing risks to patient care and research, optimizing medical record management.

Area of Science:

  • Radiology and Medical Imaging
  • Health Informatics
  • Archival Science

Context:

  • University hospital with 230,000 radiographs stored since 1974.
  • Increasing number of inactive medical records over time.
  • Need to assess the utility and risks of retaining old films.

Purpose:

  • To evaluate the risks associated with discarding inactive patient radiographs.
  • To determine the clinical and research impact of removing old films.
  • To inform hospital policy on medical record retention.

Summary:

  • Radiograph access rates were surveyed, revealing a rise in inactive records.
  • Radiologists assessed the value of prior films for 158 patients with intervals of 8+ years.
  • Simple inaccessibility risk was 0.41%, decreasing to 0.0026% with clinical disadvantage considered. Research risk was 0.97%.

Impact:

  • University hospital decided to discard radiographs of patients inactive for 10+ years, excluding research cases.
  • Potential for significant storage space reduction.
  • Establishes a precedent for optimizing medical record management in long-standing institutions.
