[3] Tannenbaum completed medical school (1994), additional training in geriatrics (2000), and a Master of Science degree in epidemiology and biostatistics (2002) at McGill University.
[8][12] Through this trial, Tannenbaum and her colleagues found that two-thirds of individuals who received EMPOWER handouts had taken it to their doctor or pharmacist, but in about half of these instances, the health care professionals discouraged deprescribing.
[8] This prompted Tannenbaum to launch and oversee the D-PRESCRIBE clinical trial, which tested whether a pharmacist-led educational intervention could decrease the number of prescriptions issued for inappropriate medication among 489 older adults in Quebec.
[7][13][14] The trial found that a pharmacist intervention resulted in greater medication discontinuation (43%) at six months than those receiving regular care.
[22] On November 17, 2021, Tannenbaum was appointed as a Member of the Order of Canada for "her leadership in geriatrics, women’s health and gender research, and for her inter-professional collaborations to optimize healthy aging across the lifespan".
