Polypharmacy and medicine regimens in older adults in residential aged care

Simplifying medication regimens for residents of aged care facilities: Pharmacist and physician use of a structured five-step medication simplification tool

BACKGROUND

Pharmacist-led medication regimen simplification using a structured approach can reduce unnecessary medication regimen complexity in residential aged care facilities (RACFs), but no studies have investigated simplification by different health professionals, nor the extent to which simplification is recommended during comprehensive medication reviews.

OBJECTIVES

To compare medication regimen simplification opportunities identified by pharmacists, general medical practitioners (GPs), and geriatricians and to determine if pharmacists identified simplification opportunities during routinely conducted comprehensive medication reviews in RACFs for these same residents.

METHODS

Three pharmacists, three GPs and three geriatricians independently applied the Medication Regimen Simplification Guide for Residential Aged CarE (MRS GRACE) to medication data for 83 residents taking medications at least twice daily. Interrater agreement was calculated using Fleiss's kappa. Pharmacist medication review reports for the same 83 residents were then examined to identify if the pharmacists conducting these reviews had recommended any of the simplification strategies.

RESULTS

Overall, 77 residents (92.8 %) taking medications at least twice daily could have their medication regimen simplified by at least one health professional. Pharmacists independently simplified 53.0-77.1 % of medication regimens (Κ = 0.60, 95%CI 0.46-0.75, indicating substantial agreement), while GPs simplified 74.7-89.2 % (Κ = 0.44, 95%CI 0.24-0.64, moderate agreement) and geriatricians simplified 41.0-66.3 % (Κ = 0.30, 95%CI 0.16-0.44, fair agreement). No simplification recommendations were included in the reports previously prepared by pharmacists as part of the comprehensive medication reviews undertaken for these residents.

CONCLUSION

Pharmacists, GPs, and geriatricians can all identify medication regimen simplification opportunities, although these opportunities differ within and between professional groups. Although opportunities to simplify medication regimens during comprehensive medication reviews exist, simplification is not currently routinely recommended by pharmacists performing these reviews in Australian RACFs.

Relationship between medication safety-related processes and medication use in residential aged care facilities

OBJECTIVE

To explore the association between the implementation of medication safety-related processes measured with the Medication Safety Self-Assessment for Long-Term Care (MSSA-LTC) tool and medication use in residential aged care facilities (RACFs).

METHODS

A descriptive cross-sectional study was conducted in Australian RACFs. Data on facility characteristics, aggregated medication use at the facility level for selected medications commonly associated with a high risk of harm and the MSSA-LTC were completed by clinical pharmacists providing clinical pharmacy services. The Spearman's correlation test was used to evaluate the association between the MSSA-LTC score and medication use. A scatter plot between the MSSA-LTC score and medication use data was generated, and a linear trend line was plotted using the least squares method.

RESULTS

Data were collected from 31 RACFs servicing 2986 residents. Most medication safety-related processes were implemented in Australian RACFs. A higher facility MSSA-LTC score was associated with a lower proportion of residents with polypharmacy (r = -.48, p = .01) and one or more benzodiazepines (r = -.41, p = .03). In addition, a negative linear trend was observed between the MSSA-LTC score and the average number of medications per resident, the proportion of residents with one or more anticonvulsants and the proportion of residents using one or more opioid analgesics.

CONCLUSIONS

This study indicates that implementing medication safety-related processes may improve medication use in RACFs.

Medicines Regimens Charted for Older People Living in Residential Aged Care: A Repeated Cross-Sectional Study Describing the Number of Medicines, Regimen Complexity, High-Risk Prescribing, and Potential Underprescribing

OBJECTIVE

We aimed to explore medicines regimens charted for older people living in residential aged care facilities (RACFs).

DESIGN

Repeated cross-sectional study using routinely collected data sampled in a cross-sectional manner at 11 time points (day of admission, then at 1, 3, 7, 14, and 30 days, and 3, 6, 12, 18, and 24 months post admission).

SETTING AND PARTICIPANTS

The cohort is set in 34 RACFs managed by a single Australasian provider. People aged ≥65 years admitted to permanent care between January 1, 2017, and October 1, 2021, with medicines charted on the date of admission.

METHODS

Medicines charted were evaluated for potentially suboptimal prescribing including number of medicines, high-risk prescribing (eg, potentially inappropriate medicines, anticholinergic burden), and potential underprescribing.

RESULTS

The 3802 residents in the final cohort had a mean age of 84.9 ± 7.2 years at admission. At least 1 example of suboptimal prescribing was identified in 3479 (92%) residents at admission increasing to 1410 (97%) at 24 months. The number of medicines charted for each resident increased over time from 6.0 ± 3.8 regular and 2.8 ± 2.7 as required medicines at admission to 8.9 ± 4.1 regular and 8.1 ± 3.7 as required medicines at 24 months. Anticholinergic drug burden increased from 1.6 ± 2.4 at admission to 3.0 ± 2.8 at 24 months. Half the residents (2173; 57%) used at least 1 potentially inappropriate medicine at admission, which rose to nearly three-quarters (1060; 73%) at 24 months admission.

CONCLUSION AND IMPLICATIONS

The total number of medicines charted for older adults living in RACFs increases with length of stay, with charted as required medicines nearly tripling. Effective interventions to optimize medicines use in this vulnerable population are required.

Embedded on-site aged care pharmacists in Australia: Insights from early adopters of a new workforce model

OBJECTIVE

To explore the roles of early adopters of Australia's embedded on-site pharmacist model in supporting quality use of medications in residential aged care facilities (RACFs).

METHODS

Qualitative semistructured interviews were conducted with 15 pharmacists working as embedded on-site pharmacists, or beyond the scope of traditional consultant pharmacist roles in Australian RACFs. Interviews were audio-recorded, transcribed and thematically analysed independently by two investigators using an inductive approach. Deductive analysis was also undertaken using a knowledge broker framework: knowledge manager, linkage agent and capacity builder.

RESULTS

Dominant themes were roles and benefits of embedded pharmacists, factors associated with success and challenges. Roles and benefits included (1) resident-level interventions and an enhanced ability to provide collaborative outcome-focussed resident-centred care, including timely input and follow-up, and improved relationships with residents, family and interdisciplinary team; and (2) system-level interventions such as contributing to clinical governance and quality improvement. Factors associated with success included personal capabilities and approach of the pharmacist, and organisational culture and sector-wide support. Challenges included pharmacist workforce shortages, perceived lack of pharmacist readiness and difficulty determining an appropriate service model. Deductive coding demonstrated roles of embedded pharmacists were consistent with all three activities of a knowledge broker.

CONCLUSIONS

This study highlights the resident- and system-level roles and benefits of embedded on-site pharmacists, and provides a framework for defining this emerging workforce model in Australian RACFs.

Deprescribing to optimise health outcomes for frail older people: a double-blind placebo-controlled randomised controlled trial-outcomes of the Opti-med study

BACKGROUND

potentially harmful polypharmacy is very common in older people living in aged care facilities. To date, there have been no double-blind randomised controlled studies of deprescribing multiple medications.

METHODS

three-arm (open intervention, blinded intervention and blinded control) randomised controlled trial enrolling people aged over 65 years (n = 303, noting pre-specified recruitment target of n = 954) living in residential aged care facilities. The blinded groups had medications targeted for deprescribing encapsulated while the medicines were deprescribed (blind intervention) or continued (blind control). A third open intervention arm had unblinded deprescribing of targeted medications.

RESULTS

participants were 76% female with mean age 85.0 ± 7.5 years. Deprescribing was associated with a significant reduction in the total number of medicines used per participant over 12 months in both intervention groups (blind intervention group -2.7 medicines, 95% CI -3.5, -1.9, and open intervention group -2.3 medicines; 95% CI -3.1, -1.4) compared with the control group (-0.3, 95% CI -1.0, 0.4, P = 0.053). Deprescribing regular medicines was not associated with any significant increase in the number of 'when required' medicines administered. There were no significant differences in mortality in the blind intervention group (HR 0.93, 95% CI 0.50, 1.73, P = 0.83) or the open intervention group (HR 1.47, 95% CI 0.83, 2.61, P = 0.19) compared to the control group.

CONCLUSIONS

deprescribing of two to three medicines per person was achieved with protocol-based deprescribing during this study. Pre-specified recruitment targets were not met, so the impact of deprescribing on survival and other clinical outcomes remains uncertain.

Deprescribing for older people living in residential aged care facilities: Pharmacist recommendations, doctor acceptance and implementation

BACKGROUND

Deprescribing is an intervention to address the high prevalence of inappropriate polypharmacy in older people living in residential aged care facilities (RACFs). Many deprescribing interventions are complex and involve several stages including initial pharmacist recommendation, subsequent acceptance of the recommendations by a prescriber and the patient, and then actual implementation.

OBJECTIVES

This study aimed to investigate pharmacist deprescribing recommendations for residents within RACFs, general practitioner (GP) acceptance, and the actual implementation of the accepted recommendations at 12-month.

METHODS

The intervention occurred as part of a randomised controlled trial and comprised a pharmacist-led medication review using an evidence-based algorithm, with the focus on identifying medications to potentially deprescribe. Consent to participate was obtained from residents (or surrogate decision-makers), RACF nursing staff and the resident's GP. Deprescribing recommendations were reviewed by GPs before implementation as part of the intervention and control arms of the trial, although control group participants continued to receive their usual medications in a blinded manner.

RESULTS

There were 303 participants enrolled in the study, and 77% (941/1222) of deprescribing recommendations suggested by the pharmacists were accepted by GPs. Of the recommendations accepted by GPs, 74% (692/ 941) were successfully implemented at the end of the follow-up visit at 12 months. The most common reason for deprescribing was because medications were no longer needed (42%, 513/ 1231).

CONCLUSION

Pharmacist-led deprescribing recommendations arising from an algorithm-based medication review are acceptable to doctors and can have a significant impact on reducing the number of inappropriate medications consumed by older people in RACFs.

What types of information do pharmacists include in comprehensive medication management review reports? A qualitative content analysis

BACKGROUND

Comprehensive medication management reviews are an established intervention to identify medication-related problems, such as the prescribing of potentially inappropriate medications, and under- and over-prescribing. However, the types of information included in written reports of comprehensive medication management reviews, beyond types of medication-related problems, are unknown.

AIM

This study aimed to explore the types of information Australian pharmacists include in their written reports following comprehensive medication management reviews.

METHOD

Australian consultant pharmacists were invited to upload their 10 most recent written reports of their domiciliary-based comprehensive medication management reviews. A random selection of the reports, stratified by each pharmacist, were included for qualitative content analysis.

RESULTS

Seventy-two de-identified reports from eight consultant pharmacists located in five of the eight Australian States and Territories were included for analysis. From the evaluated reports, four major categories of information were identified: (1) patient details such as date of interview (n = 72, 100%) and medicine history (n = 70, 97%); (2) pharmacist assessment including assessment of the patient (n = 70, 97%), medicines management (n = 68, 94%) and medicine-related issues (n = 60, 83%); (3) pharmacist recommendations, specifically pharmacological recommendations (n = 67, 93%); and (4) patient-centred experiences such as perspectives on medicines (n = 56, 78%). Reporting of patient-centred experiences appeared most variably in the included reports, including patient concerns (n = 38, 53%), willingness for change (n = 27, 38%), patient preferences (n = 13, 18%), and patient goals (n = 7, 10%).

CONCLUSION

Pharmacists within our study included a wide variety of information in their comprehensive medication management review reports. Aside from medication-related problems, pharmacists commonly provided a holistic assessment of the patients they care for. However, variability across reports has the potential to impact consistent service delivery.
