A Collaborative Intervention for Streamlining Medication Appropriateness and Deprescribing within Integrated Healthcare Teams
Overall, we expect that by using the tool pharmacists will be able to help reduce the number of pills people take, reduce drug costs, reduce harms from medication use and improve quality of life for older adults living with frailty and their loved ones.
About the Project
Medication use is common in older adults living with frailty. Polypharmacy is not a benign problem of many medications but represents an increased risk of adverse drug events, drug-related emergency department visits and hospitalization. Estimates suggest that in older adults approximately 40% of emergency department visits are drug-related. Once an individual has suffered a serious drug-related event their medications may be re-evaluated but this point in time is too late. Identification of individuals at risk of medication misadventure and subsequent deprescribing in a safe way should be the goal of care. Primary care clinics are strategically positioned to identify frail individuals at risk for a drug-related adverse events and prevent the event before it happens by safely stopping the high-risk therapy.
We propose the collaborative development of a simple intervention tool using the expertise of pharmacists, nurses, primary care physicians, geriatricians and caregivers engaged in care of older adults living with frailty. This tool will identify and target deprescribing for older adults living with frailty using an approach that can used by pharmacists working in collaborative health teams (two in Nova Scotia, and two in New Brunswick). The intervention will include frailty assessment. Using the tool, the pharmacists will initiate deprescribing and monitor their frail patients to successful deprescribing within their health care team. Nursing home patients are amongst the frailest of our seniors and polypharmacy is common in these environments. In addition to primary care sites the tool will be piloted in Nursing Home sites in New Brunswick and Nova Scotia.
We hypothesize that making positive changes to medication regimens by deprescribing in older adults living with frailty will have a number of benefits. The most obvious will be the reduced drug costs. This is a relatively small cost savings but it can be a significant benefit to low income older adults. In addition, deprescribing can have a greater impact for public drug payers and the cumulative cost-avoidance could theoretically be reinvested into other health initiatives. We also hypothesize that deprescribing will reduce medication misadventure which will lead to a reduction in emergency department visits and hospitalizations. This is where the most significant cost savings can be realized due to deprescribing activity. These benefits will be able to be measured using drug cost data and through analysis of administrative databases such as the discharge abstract database. We will capture the positive impact on patients which will include reduced drug use, reduced pill burden and hopefully improved quality of life.
