Clinical Trial Summary
Successful medication management is an essential instrumental activity of daily living (IADL)
for older adults with polypharmacy; however, between 40%-70% of older adults fail to take
their medications as prescribed. Providing interventions to address medication management and
restore performance for this IADL is within the scope of practice for occupational therapy
(OT), however, there is paucity of evidence for OT interventions to improve medication
management in community-dwelling older adults. We have developed a tailored medication
management intervention (TIMM) for community-dwelling older adults which recognizes the
unique context in which medication management occurs (the home) and addresses the personal
and environmental barriers experienced by older adults. TIMM is delivered in the home, by an
OT, and in collaboration with a pharmacist to reduce inappropriate polypharmacy.
Description:
Almost 70% of older adults experience multimorbidity and medication is often the first
intervention used to manage it. In fact, 90% of older adults take at least one medication and
36% take 5 or more, commonly known as polypharmacy. When taken correctly, medication can
extend life-expectancy and improve quality of life. However, estimates show 40-75% of
community-dwelling older adults are nonadherent, or deviate from their medication regimen.
These older adults are at an increased risk of nonadherence because the physical changes
associated with multimorbidity including decreased memory, fine motor skills, and visual
acuity and because of the complexity polypharmacy adds to a medication routine. Nearly 43% of
older adults with polypharmacy take medications that are inappropriate and can cause negative
long term physical and cognitive function, which further complicates the mediation management
process.
Nonadherence has significant consequences which include increased health care costs, falls,
institutionalization, and decreased medication effectiveness, quality of life. In fact,
improving medication adherence has been identified as a public health concern by the World
Health Organization. Despite this, interventions designed to improve adherence in older
adults remain largely ineffective. The majority of interventions are disease or medication
specific or are implemented with a "one size fits all" approach (e.g. providing standard pill
organizers that may be difficult for some older adults to open). Furthermore, interventions
are often implemented in a clinical setting such as doctor's office or hospital and do not
consider the unique home environment where medication management typically occurs. Home
environments can offer support (i.e. caregiver to set up medications) or barriers (i.e. low
lighting that makes medications difficult to see) to medication management. Given the
complexity of each older adult's risk factors and home environment, a more tailored,
individualized approach must be considered.
Tailored, individualized interventions aimed at remediating the environmental barriers in the
home have been successful in improving daily activity performance for older adults. However,
this type of intervention has not been tested specifically to improve medication adherence in
older adults with multimorbidity and polypharmacy. We propose a tailored, individualized
medication management intervention (TIMM) for community-dwelling older adults with
multimorbidity and polypharmacy. TIMM is an interdisciplinary, compensatory intervention
which consists of: 1) an initial in-home evaluation of medication management ability,
individual risk factors, and identification of environmental barriers to independence; 2) a
medication review by a pharmacist to address polypharmacy; and 3) tailored intervention by an
occupational therapist to improve adherence by reducing barriers to medication management.
We will conduct an equivalency randomized control trial to examine the feasibility,
acceptability and preliminary efficacy of TIMM delivered remotely and in-person. The use of
telehealth to deliver occupational therapy interventions for older adults has become more
widely utilized, especially during the last two years. Remote interventions remove many of
the barriers to in-home care including access and cost and have been shown to be an effective
delivery method for OT and other medical services for older adults. Participants in the
treatment group will receive the intervention delivered remotely, and participants in the
waitlist control group will receive the intervention in-person, upon completion of their
control period.
