On March 12th, the Department of Medicine and Translational Medicine had the pleasure of hosting Dr. Leah Nemiroff, a staff Geriatrician and Assistant Professor in the Division of Geriatric Medicine at Queen’s University. Dr. Nemiroff introduced the topic of frailty, emphasizing it’s not just another “F-word” and why it matters in medicine.
The concept of clinical frailty was extensively discussed during Dr. Nemiroff’s presentation. It can generally be described as, “A medical syndrome with multiple causes and contributors that is characterized by diminished strength, endurance, and reduced physiological function that increases an individual’s vulnerability for developing increased dependency and/or death.”1 Often times in practice, it may be difficult to provide optimal care when feeling frustrated, but Dr. Nemiroff provided us with a quote from Dr. Rockford that keeps her motivated, “Knowledge is the best remedy for the frustration that we feel.”
The field of geriatrics is much needed in Canada; however, we may be facing a shortage as the country’s population is aging and there are only about 304 geriatricians present.2 This field is particularly complex as individual differences matter more as people age and everyone is heterogeneous in their mortality risk. What adds to the complexity is the predisposing factors individuals are introduced to throughout their life. In general, the more predisposing factors one is introduced to means the fewer precipitating factors are needed to become frail.
It is as important to identify and grade frailty as it is to understand it. Dr. Nemiroff introduced the frailty phenotype, first proposed by Fried and Watson. The Fried frailty phenotype, including five components interlinked to form a cycle of frailty: weakness, slowness, exhaustion, low activity and weight loss, operationalizes frailty.3 In addition, Dr. Nemiroff spoke about the Clinical Frailty Scale, emphasizing the importance of quantifying frailty. The Clinical Frailty Scale ranges from one to nine, including classifications such as “very fit, vulnerable, moderately frail, and terminally ill.”4 It is important to characterize one on how frail they are as practice and treatment can be tailored towards their score. However, it is important to note that this is a baseline measurement and should be taken two weeks before an illness. If this score is taken after a surgery or during an illness, it will alter the actual score of frailty.
It is well understood that a person can progress through the stages of frailty, however an interesting question that was brought up is if it’s possible to become less frail. Dr. Nemiroff mentioned that if one is in the very early stages of frailty, reversal and prevention is possible using preventative interventions such as exercise and proper nutrition. A staggering statistic mentioned by Dr. Nemiroff is that patients in hospital care units are told or required to do around 40 minutes of physical activity a day, including seated exercises. This may be reasonable for patients with physical disabilities, however Dr. Nemiroff advocates for physical activity and exercise to prevent and treat frailty. The topic of polypharmacy, taking over five medications without evidence-based reasoning, is important to consider when looking at personalized treatment options.5 Dr. Nemiroff discussed the positive changes she’s seen when removing unneeded medications from a patient’s treatment plan.
Finally, Dr. Nemiroff went over outcomes of frail patients after ICU. She mentioned a critical study done in the field by Bagshaw et al., finding frail patients were older, more likely to be female, and had more comorbidities and greater functional dependence than those who were not frail.6 Compared to nonfrail survivors, frail survivors were more likely to become functionally dependent, had a lower quality of life and were more often readmitted to hospital.6
During our post-Grand Round discussion, we discussed if biomarkers may be used to better describe frailty. There are certain biomarkers that may be linked to scores on the Clinical Frailty Scale, however individuals are different, meaning they may have different biomarkers. In addition, we discussed the importance of having a conversation about frailty early on to combat stigma surrounding aging. Understanding that patients’ views on frailty is critical to provide optimal care.
Finally, when asked about making the right career choice, Dr. Nemiroff gave us some meaningful advice. From her personal experience; pivoting from studying long-finned pilot whales to practicing geriatric medicine, she explained that career paths can often change, and we should be our own person.
It was a pleasure hosting Dr. Nemiroff at Grand Rounds. On behalf of the Department of Medicine and the TMED 801 class, we thank you for giving us insight into your world of geriatric medicine.
