title: Usability study of a novel, self-lighted, disposable speculum: military applications.
abstract: METHODS
  Data collected from a postutilization questionnaire were used to evaluate the usability of the OfficeSPEC disposable vaginal speculum, specifically the effectiveness, efficiency, and acceptability, in clinical, hospital, and austere environments.
  
  
  RESULTS
  Usability data analysis showed the OfficeSPEC speculum had an effectiveness rating of 4.6/5, efficiency rating of 4.5/5, and acceptability rating of 4.6/5; overall usability in deployed environments was favorable. The overall rankings were 3.4 for plastic, 4.2 for metal (p < 0.001), and 4.5 for OfficeSPEC (p < 0.001). Cost analysis of the OfficeSPEC placed the disposable speculum as a reasonable alternative with yearly cost of $129,200, compared to traditional metal ($209,100) and plastic ($319,175).
  
  
  CONCLUSIONS
  By evaluating the OfficeSPEC speculum within a usability framework, it proved to be practical, viable alternative in all environments, particularly in the forward deployed environment.
