The Medicaid drug program in Louisiana: critique of the Hefner-Pracon Study.
Critiqued is a study that concluded a restrictive state Medicaid formulary caused an adverse impact on health and increased the cost of nondrug services. The study is criticized because the state's drug restrictions were not of major import, the before and after date were handled in a simplistic manner, and no distinction was made between correlation and causation. Readers should proceed cautiously before accepting the results of research projects sponsored or disseminated by interested parties.
