A simple answer is that a consultant pharmacist is a pharmacist who is paid to provide expert advice on the use of medications by individuals or within institutions, or on the provision of pharmacy services to institutions.
The phrase "consultant pharmacist," coined by George F. Archambault who is referred to as the "founding father" of consultant pharmacy, originated in the nursing home environment when a group of innovative pharmacists focused on improving the use of medications in these facilities.
Consultant Pharmacists are now practicing in a wide variety of other settings, including subacute care and assisted living facilities, psychiatric hospitals, hospice programs, and in home and community-based care -- wherever seniors reside. Consultant Pharmacists are defined by their common commitment to enhance the quality of care for all older persons through the appropriate use of medication and promotion of healthy aging.
