Canadian Deprescribing Network Annual Report 2016 CaDeN ReCaD Canadian Deprescribing Réseau canadien Network pour la déprescription The Canadian Deprescribing Network is a group of health care leaders, clinicians, decision- makers, academic researchers and patient advocates working together to mobilize knowledge and promote the deprescribing of inappropriate medications in Canada. The Network’s key objectives are to: • Reduce harm by raising awareness and decreasing the use of inappropriate medications for seniors by 50% by 2020. • Promote health by ensuring access to safer drug and non-drug therapies. The Canadian Deprescribing Network is initially focusing on three classes of medications that should be considered for deprescribing in seniors: • Benzodiazepines; • Proton pump inhibitors; and • Long-acting sulfonylureas. What is Deprescribing? Deprescribing is the planned and supervised process of reducing or stopping medications that may no longer be of benefit or may be causing harm. The goal is to reduce medication burden and harm, while maintaining or improving quality of life.

However, as we get older, the conditions are able to lead meaningful benefits and risks of medication may change. lives with the help of safe and effective With age, some medications become prescription medications. As the number unnecessary or even harmful because of chronic diseases increase with age, of short-term or long-term side effects, so do prescriptions. Seniors with three or drug-drug interactions, and drug-related more chronic conditions take an average hospitalizations. of six different medications (CIHI 2014). How many prescription medications are Canadian seniors taking? 2 out of 3 Canadians over 1 out of 4 Canadians over the age of 65 take at least the age of 65 take at least 5 different prescription 10 different prescription medications. medications.

Canadian seniors who take at least one inappropriate medication 47% 42% Some medications may be 39% unnecessary, potentially 31% inappropriate and even harmful to seniors. These medications, compiled on the Beers criteria list, are known to increase the risk of over 65 over 85 adverse effects. years old years old (Morgan et al. 2016; 2013 CIHI data) Adverse Effects Risk of Drug-Drug Interactions Adverse effects of medication may include side effects, drug 8-fold interactions, falls, fractures, greater risk memory problems and risk of death. Older women are typically more of susceptible to adverse effects 4-fold medications and more likely to be greater risk prescribed risky medication. This is because women have a longer average life expectancy than men, suffer from more chronic conditions Low risk and typically take more medication. Female biology and physiology also increase the risk of harmful effects 2 5-7 8-10 of medication. Number of medications (Johnell and Klarin 2007) 6 Cost of Inappropriate Medications for Seniors Medications in general are costly. Inappropriate medications raise greater concern, because of the added indirect costs associated with drug harms and hospitalizations. Cost of commonly prescribed potentially inappropriate medications among Canadian seniors: $250 million $97 million Proton-pump inhibitors Antipsychotics Increased risk of fractures, memory Increased risk of memory and problems, pneumonia, Clostridium concentration problems, falls, fractures, difficile infections and diarrhea, kidney stroke, dizziness, confusion, diabetes disease, and low levels of magnesium and weight gain. and vitamin B12 in the blood.

(Morgan et al. 2013) Total costs of inappropriate medication among Canadian seniors $419 million $1.4 billion Canadians spend $419M per year Canadians spend $1.4B per year in on potentially harmful prescription health care costs to treat harmful medications. This does not include effects from medications, including hospital costs. fainting, falls, fractures and hospitalizations. (Morgan et al. 2016; 2013 CIHI data) Why Focus on Deprescribing? 7 Falls, Fractures and Seniors 9% of all emergency department visits Falls are the leading cause of injury hospitalizations for seniors across the country, contributing to 9% of all emergency department visits (CIHI 2011). Certain inappropriate medications, such as benzodiazepines, antipsychotics and long-acting sulfonylureas, can increase the risk of falls by 50% because they cause side effects like 50% concentration and balance problems, or dizziness.
