VA Health Care:
VA's Management of Drugs on Its National Formulary
HEHS-00-34, Dec 14, 1999
Pursuant to a congressional request, GAO reviewed how the Department of Veterans' Affairs' (VA) manages its national formulary and how drugs other than those on the formulary are made available to veterans.
GAO noted that: (1) VA's national formulary is administered by the Pharmacy Benefits Management Strategic Healthcare Group (PBM), a strategy modeled after one commonly used in private health care systems; (2) PBM adds drugs to, and deletes drugs from, the national formulary on the basis of a review of current literature related to drugs' safety and efficacy and the contributions they can make in treating veterans; (3) PBM also performs drug class reviews that determine which drugs are therapeutically interchangeable--essentially equivalent in terms of efficacy, safety, and outcomes; (4) this determination allows VA to obtain better prices for one or more of these drugs by using competitively bid contracts; (5) PBM safeguards against inappropriate use by requiring that clinical guidelines be followed when some drugs are used, limiting prescribing privileges in certain cases to specially trained physicians; (6) in other cases, PBM requires consultation with a specialist before a drug can be prescribed; (7) drugs not on the national formulary may be available to veterans through independent formularies maintained by Veterans Integrated Service Networks (VISN) and some medical centers; (8) these formularies are designed to provide local facilities flexibility by giving physicians access to additional drugs that meet the special needs of their patients; (9) if prescribers believe that a patient needs a drug that is not on the national, VISN, medical center formulary, they may request a nonformulary drug waiver, which would allow the prescriber to provide the nonformulary drug; (10) new drugs may be added to VISN and medical center formularies immediately upon Food and Drug Administration approval; (11) however, VA policy states that new drugs generally may not be added to the national formulary until they have been on the U.S. market for at least 1 year because VA believes veterans may be exposed to potential side effects that are not identified during the drug review and approval process; and (12) this potentially allows veterans treated in some facilities to benefit from new drugs before veterans in other locations, but it may also expose them to any side effects that are identified within the first year of a drug's general use.
