title: Adaptation of the World Health Organization's medical eligibility criteria for contraceptive use for use in the United States.
abstract: BACKGROUND
  The Centers for Disease Control and Prevention (CDC) recently adapted global guidance on contraceptive use from the World Health Organization (WHO) to create the United States Medical Eligibility Criteria for Contraceptive Use (MEC). This guidance includes recommendations for use of specific contraceptive methods by people with certain characteristics or medical conditions.
  
  
  METHODS
  CDC determined the need and scope for the adaptation, conducted 12 systematic reviews of the scientific evidence and convened a meeting of health professionals to discuss recommendations based on the evidence.
  
  
  RESULTS
  The vast majority of the US guidance is the same as the WHO guidance and addresses over 160 characteristics or medical conditions. Modifications were made to WHO recommendations for six medical conditions, and recommendations were developed for six new medical conditions.
  
  
  CONCLUSIONS
  The US MEC is intended to serve as a source of clinical guidance for providers as they counsel clients about contraceptive method choices.
