A working group utilizing a three-step modified Delphi method to develop consensus of a checklist of factor to consider when evaluating a FDC product for formulary inclusion. The group developed a comprehensive list of factors that are to be considered when evaluating a FDC for addition and included point related to: evidence of improved outcomes, synergistic effect, chronic indication, total number and frequency of doses, potential for medication errors, separate indications for each component, use in extemporaneous preparation, drug patency expiry, and cost Impact Determining whether a FDC has benefits to a health care organization requires careful review of the evidence, practicality, and cost.
