It has been reported that up to one-quarter of patients who visit emergency departments (ED) due to adverse drug reactions (ADRs) are admitted to hospital. ADRs resulting in hospital admission generally represent more severe reactions and require more resources to treat. One recent study found that ED visits and hospital admissions due to ADRs among seniors in Canada cost an estimated $35.7 million, with more than 80% of those costs arising from hospitalization. 

Statistics show around one in three unplanned hospital admissions for older Australians are related to issues with their medicines – and half are preventable. A new educational program targeting health professionals, particularly nurses and pharmacists, aims to reduce the rate of adverse medicine events in patients aged 75 and over. “NPS MedicineWise is encouraging all health professionals, including pharmacists and nurses, to adopt a coordinated approach to medicines management as an important aspect of a care plan for an older person, and to engage older people, their family and carers as active partners in health decisions."

The purpose of this review was to identify evidence-based interventions related to medication management and the community-dwelling older adult. The focus of this review was interventions that fall within the scope of practice of the registered nurse. The guidelines do not address the specific intervention of medication prescribing. However, the interventions are applicable to professional nurse providers whether they are prescribing or not. This chapter discusses risk factors for problems in medication management followed by evidence-based interventions in areas of medication reconciliation, medication procurement, medication knowledge, physical ability, cognitive capacity, intentional nonadherence, and ongoing monitoring.

Non-pharmacological therapies for common chronic medical conditions in older patients are underused in clinical practice. We propose a protocol for the assessment of the evidence of non-pharmacological interventions to prevent or treat relevant outcomes in several prevalent geriatric conditions in order to provide recommendations.

This is a comprehensive outline detailing pain management in older people containing information on common challenges, assessment treatment and medication to use. 

This chapter of the Introduction to Behavioural and Psychological Symptoms of Dementia (BPSD): A Handbook for Family Physicians outlines the general approaches to the use of psychotropic medications in the management of behavioural and psychological symptoms in dementia.   22 pages.

Focused Research

The Research Institute for Aging (RIA) has been conducting projects based around a variety of themes- one of which is “optimizing medications for seniors.”

Emerging Priorities in Aging

Conferences & Workshops - Aging Research & Innovation Forum • October 26, 2012 • Kingston, ON

On October 26, 2012, as part of our series of Aging, Research & Innovation Forums, over 100 educators, clinicians, students, caregivers and researchers from across Ontario attended the Emerging Priorities in Aging conference at Portsmouth Olympic Harbour Restaurant in Kingston to discuss ideas, projects and research about the care and welfare of older adults.

Polypharmacy is defined as the use of five or more prescription medications.   Polypharmacy is common among seniors and can lead to reduced adherence with medication regimens and problems with drug interactions. (4) Medication-related problems are common, costly, and often preventable in older adults and lead to poor outcomes. 

Why is this Important?

  • 27% of seniors reported taking five or more medications on a regular basis. (4)
  • 12% of seniors taking five or more medications experienced a side effect that required medical attention compared with 5% of seniors taking only one or two medications(4)
  • 27% of adverse drug events (ADEs) in primary care were preventable, with most problems occurring at the ordering and monitoring stages of care (1)
  • The number of prescription medications was associated with the rate of emergency department use. (4)
  • Less than 50% of all seniors reported receiving a prescription medication review from their physician identifying  potential side effects. (4)
  • The number of medications being taken increases the risk of adverse drug reactions (ADRs), which can increase the likelihood of hospital visits.

Key Considerations

  • When conducting a medication review ask for all prescribed medications, OTC and herbal preparations
  • Monitor compliance of medication adherence, ask about common side effects and adverse occurrences especially when new medications have been ordered
  • As patients become more frail, the potential harm from medications must be weighed against the potential benefits (1)
  • Follow the Beers criteria when prescribing and evaluating: 
    i)    medications to avoid in older adults regardless of disease or conditions
    ii)   medications considered inappropriate when used in older adults with certain conditions or syndromes
    iii)  medications to consider for use in certain individuals recognizing the potential for misuse and harm is substantial (5)

This presentation describes an approach to safe prescribing for older patients. It explores the significance and causes of polypharmacy and identifies contributory factors to medication related problems and ways to avoid them.
