title: Relative value of analog and digital teaching files.
abstract: OBJECTIVE
  This study was performed to determine if it is financially reasonable for radiology residency programs that create and maintain their own teaching files to switch from analog teaching files (ATFs) to digital teaching files (DTFs).
  
  
  METHODS
  Radiology residency program directors were surveyed electronically about the monetary value and importance of conventional ATFs and DTFs. The costs for maintaining each type of file were calculated at the authors' institution.
  
  
  RESULTS
  Surveys were sent to the program directors of all 197 accredited radiology residencies. Responses were received from 48 (24%). DTFs were scored as more important than ATFs, but the difference was not significant (P = .22). DTFs were rated as less complete (P = .01) but more current (P << .001) than ATFs. DTFs included the American College of Radiology Learning File (85%), in-house productions (77%), and other commercially available products (63%). Thirty percent of respondents had a DTF integrated into a picture archiving and communication system, and 28% reported having a technician dedicated to the teaching file. Program directors ascribed total median dollar values of $250 and $3,000 per year to their ATFs and DTFs, respectively. The annual costs at the authors' institution were much higher than these ascribed values: $44,720 ($91 per case) for maintaining a DTF produced in house and $24,601 ($50 per case) for maintaining an ATF, excluding physician time.
  
  
  CONCLUSIONS
  Program directors are more willing to pay for a DTF than an ATF. For both, the costs of maintenance are great and the relative monetary value is low.
