Developed by Vanderbilt University researchers and a national consensus panel of experts (Brown et al. 1998), the MMIS is a collaborative approach to identifying, assessing, and resolving medication problems in community-dwelling older adults. These system targets potential medication problems include both drug use and symptoms associated with specific adverse drug effects. The process, which includes consultation with a specially trained clinical pharmacist and an interdisciplinary care-management team and a follow-up with the client's physician, adheres to periodically updated guidelines established by a Geriatric Advisory Panel composed of pharmacists, physicians, social workers, and nurses.
