Abstract
Background: A significant problem in older people (aged ‡65 years) is the use
of potentially inappropriate medications (PIMs), including those with sedative
and anticholinergic properties. However, effective intervention strategies
have yet to be identified. The Drug Burden Index (DBI) is an evidence-based
tool that measures a person’s total exposure to medications with sedative and
anticholinergic properties and has been shown to be independently associated
with impairment in cognitive and physical function.
Objective: The main aim of the study was to investigate whether Home
Medicines Review (HMR) services by pharmacists for community-dwelling
older people would lead to an improvement in the use of medications, as
measured by a decrease in the DBI score. The study also aimed to investigate
the (i) distribution of DBI scores and PIMs among older people living in the
community, and (ii) impact of pharmacists’ recommendations on DBI scores
and PIMs.
Methods: A retrospective analysis of medication reviews was performed for
372 community-dwelling older people (aged ‡65 years) who received an
HMR service from the pharmacist. The main outcome measure was the total
DBI score at baseline and post-HMR. The data were also examined to determine
the extent of PIM use (2003 Beers’ criteria), and the number and
nature of pharmacists’ recommendations.
Results: Overall, medications contributing to the DBI (i.e. medications with
sedative or anticholinergic properties) and PIMs were identified in 60.5%
(n = 225) and 39.8% (n = 148) of the patients, respectively. Following pharmacist
recommendations during the HMR service, medications contributing
to the DBI were identified in 51.6% (n = 192) of the patients. A statistically

significant reduction in the sum total of DBI scores for all patients was
observed following pharmacists’ recommendations during the HMR service
(206.9 vs 157.3, p < 0.001). Pharmacists’ recommendations also led to a
decrease in the use of PIMs, which were identified in 28.2% (n = 105) of the
patients following the HMR service.
Conclusion: When the DBI is used for evaluation, pharmacists’ recommendations
during HMR services, if acted upon, may effect changes in the prescribing
of sedative and anticholinergic medications, thereby substantially
reducing the patient’s drug burden. Future studies should focus on whether
such a decrease may translate into functional improvements. The study also
