Informed by her experience as a geriatrician, Dr. Rochon is leading international research to improve providers understanding of how to prescribe drugs to older people, particularly women whose advanced age, chronic conditions, and use of multiple medications make them vulnerable to adverse events. In particular, her research has informed initiatives to reduce the unnecessary use of antipsychotic drug therapy and has led to the development of the prescribing cascade concept. Prescribing cascades are becoming increasingly common in older adults, occurring when an individual has a side effect to a drug and their doctor misinterprets the reaction as a new medical condition and prescribes additional medication. Dr. Rochon is helping clinicians think carefully about their prescribing habits to reduce potentially inappropriate prescribing and to inform de-prescribing strategies.
