Deprescribing Education vs Usual Care for Patients With Cognitive Impairment and Primary Care Clinicians: The OPTIMIZE Pragmatic Cluster Randomized Trial

Aligning Medications With What Matters Most: Conversations Between Pharmacists, People With Dementia, and Care Partners

INTRODUCTION

Successful deprescribing for people with dementia (PWD) depends on communication about medication-related priorities between PWD, care partners and clinicians. The objective of this study was to gain in-depth knowledge of how elicitation of PWD and care partner medication-related priorities during a deprescribing intervention shaped discussions with pharmacists about medications.

METHODS

Qualitative analysis of audio-recorded interactions between pharmacists and patient-care partner dyads in a pilot study of a pharmacist-led deprescribing intervention for PWD in primary care. Patients ≥ 65 years taking ≥ 7 medications and care partners were recruited from an integrated delivery system in Colorado and a community-based medical practice in Maryland. Qualitative content analysis was used to analyze 82 transcripts from encounters with 55 patient-care partner dyads.

RESULTS

The mean (SD) age of PWD was 81 (8.1) years; 45% were women, 33% Black, and 15% Hispanic. PWD took an average of 13 (±5.3) medications at baseline. Care partners were on average 66 (13) years of age and most were spouses/partners of the PWD. Content analysis identified five themes: (1) Reducing medication-related treatment burden; (2) Alleviating burdensome symptoms; (3) Maintaining cognition and function; (4) Discussion of tradeoffs; (5) Challenges to deprescribing. After eliciting patient and care partner priorities, pharmacists recommended both deprescribing and prescribing.

CONCLUSION

Findings from this secondary analysis of a pilot deprescribing intervention suggest eliciting medication-related priorities of PWD and care partners can support goal-concordant care. These results can inform development of interventions to optimize medications for this population.

An Educational Intervention to Promote Central Nervous System-Active Deprescribing in Dementia: A Pilot Study

BACKGROUND

Central nervous system (CNS)-active polypharmacy (defined as concurrent exposure to three or more antidepressant, antipsychotic, antiseizure, benzodiazepine, opioid, or nonbenzodiazepine benzodiazepine receptor agonists) is associated with significant potential harms in persons living with dementia (PLWD).We conducted a pilot trial to assess a patient nudge intervention's implementation feasibility and preliminary effectiveness to prompt deprescribing conversations between PLWD experiencing CNS-active polypharmacy and their primary care clinicians ("clinicians").

METHODS

We used the electronic health record to identify PLWD prescribed CNS-active polypharmacy in primary care clinics from two health systems. Clinics were assigned to intervention (n = 10) or control (n = 12), with PLWD in intervention clinics mailed an educational brochure to prompt discussion with clinicians about the appropriateness of their CNS-active regimen. We conducted chart reviews for evidence of documentation related to these medications and used the electronic health record (EHR) to assess preliminary effectiveness 120 days after sending the brochure (e.g., number of CNS-active medications prescribed, change in total standardized daily dose [TSDD] of CNS-active medications, and change in prevalence of CNS-active polypharmacy). We interviewed 10 clinicians from intervention clinics to assess their perceptions about the acceptability of the intervention.

RESULTS

PLWD in the intervention group (n = 61) and control group (n = 68) had an average age of 72.4 years (standard deviation [SD] 9.7), 62.8% were female, and 84.5% were white. We did not find any documented evidence of conversations related to CNS-active medications between PLWD who received the brochure and their primary care clinicians. After 120 days, there was no significant between-group difference in the mean number of CNS-active medications prescribed (- 1.0 [SD 1.3] versus - 1.0 [SD 1.3]), mean TSDD (- 1.6 [SD 6.0] versus - 1.3 [SD 5.8]), or the percentage of patients with CNS-active polypharmacy (52.6% versus 50.4%). Interviews with clinicians suggested they were aware that combinations of CNS-active medications were not ideal; however, they reported inheriting patients who were already on these medications, and they did not have sufficient clinic time or access to safer alternatives to overcome patient hesitation to deprescribe.

CONCLUSIONS

A direct-to-patient mailed educational brochure did not demonstrate feasibility in provoking deprescribing conversations between PLWD and clinicians or preliminary effectiveness in decreasing CNS-active polypharmacy.

Associations between sex, race/ethnicity, and age and the initiation of chronic high-risk medication in US older adults

BACKGROUND

High-risk medication use is associated with an increased risk of adverse events, but little is known about its chronic utilization by key demographic groups. We aimed to study the associations between age, sex, and race/ethnicity with new chronic use of high-risk medications in older adults.

METHODS

In this retrospective cohort study, we analyzed data from older adults aged ≥65 years enrolled in a national health insurer who started a high-risk medication between 2017 and 2022 across 16 high-risk medication classes. We used generalized estimating equations to estimate the associations between sociodemographic classifications and the onset of chronic high-risk medication use after initiation (≥90 days' supply across ≥2 fills within 180 days). We adjusted the analyses for sociodemographic and clinical patient characteristics and added three-way interaction terms for race/ethnicity, sex, and age to explore whether the outcome varied across different subgroups of race/ethnicity, age, and sex.

RESULTS

Across 2,751,069 patients (mean age: 74 years [SD = 7], 72% White, 60% Female), 406,075 (15%) became new chronic users of ≥1 high-risk medication. Compared to White older adults, Asian (RR = 0.81, 95% CI: 0.79-0.84), Black (RR = 0.92, 95% CI: 0.90-0.94), and Hispanic (RR = 0.85, 95% CI: 0.83-0.86) older adults had a lower risk of becoming new chronic users. Men had a higher risk compared to women (RR = 1.09, 95% CI: 1.08-1.10). Age was not significantly associated with new chronic high-risk medication use (≥75 years: RR = 1.00, 95% CI: 1.00-1.01). We observed differences across some medication classes, like benzodiazepines, first-generation antihistamines, and antimuscarinics for which non-White older adults were at a higher risk. The joint presence of specific age, sex, and race/ethnicity characteristics decreased the risk of becoming a new chronic user (e.g., Hispanic/Female/65-74 years: RR = 0.96, 95% CI: 0.94-0.99).

CONCLUSIONS

New chronic high-risk medication use varied across older adults by sociodemographic characteristics, suggesting the need to individualize medication optimization approaches and better understand how systematic barriers in access to health care may influence differences in high-risk medication use in older adults.

A comparison of changes in drug burden index between older inpatients who fell and people who have not fallen: A case-control study

OBJECTIVE

Older inpatients who fall are often frail, with multiple co-morbidities and polypharmacy. Although the causes of falls are multifactorial, sedating and delirium-inducing drugs increase that risk. The aims were to determine whether people who fell had a change in their sedative and anticholinergic medication burden during an admission compared to people who did not fall. A secondary aim was to determine the factors associated with change in drug burden.

METHODS

A retrospective, observational, case-control study of inpatients who fell. Two hundred consecutive people who fell were compared with 200 randomly selected people who had not fallen. Demographics, functional ability, frailty and cognition were recorded. For each patient, their total medications and anticholinergic and sedative burden were calculated on admission and on discharge, using the drug burden index (DBI).

RESULTS

People who fell were more dependent and cognitively impaired than people who did not fallen. People who fell had a higher DBI on admission, than people who had not fall (mean: .69 vs .43, respectively, p < .001) and discharge (.66 vs .38, p < .001). For both cohorts, the DBI decreased between admission and discharge (-.03 and -.05), but neither were clinically significant. Higher total medications and a higher number DBI medications on admission were both associated with greater DBI changes (p = .003 and <.001, respectively). However, the presence (or absence) of cognitive impairment, dependency, frailty and single vs multiple falls were not significantly associated with DBI changes.

CONCLUSIONS

In older people, DBI medications and falls are both common and have serious consequences, yet this study was unable to demonstrate any clinically relevant reduction in average DBI either in people who fell or people who had not fallen during a hospital admission.

Use of the Patient Portal to Discuss Medications Among People with Dementia and Their Care Partners

BACKGROUND

People with dementia (PWD) often use potentially inappropriate medications (PIM), exposing them to harm. Patient portals are a promising platform for delivering deprescribing educational interventions to reduce PIM use, yet little is known about how PWD and their care partners use patient portals to communicate with clinicians about medications.

OBJECTIVE

To characterize the content of patient portal messages relating to medications among PWD, care partners, and clinicians, to inform development of a portal-based intervention to reduce use of PIM among PWD.

DESIGN

Descriptive analysis of data from the electronic health record and qualitative analysis of patient portal messages.

PARTICIPANTS

Adults 65 and older, categorized as having dementia based on EHR algorithm, who received care in an academic health system from 2017 to 2022.

APPROACH

Electronic health record data were analyzed using descriptive statistics. Qualitative coding identified topics raised in portal messages.

KEY RESULTS

A total of 399 message threads from 159 unique patients were analyzed. Patients were on average 78.4 years old (SD 8.0). Most (65%) were female, White (76%), and non-Hispanic/Latinx (96%); 15% had a registered proxy portal user. The most common topics raised in portal messages were logistics (42%), concerns about adverse effects/treatment burden (25%), asking for new medications (23%), and openness to stopping medications (21%). Qualitative analysis revealed three main themes related to deprescribing: (1) Opportunities to deprescribe, (2) challenges to deprescribing, and (3) medication-related counseling in the portal.

CONCLUSIONS

PWD and their care partners frequently raise medication concerns in the portal, suggesting it is a promising platform for delivering deprescribing interventions for this population. Future research should identify characteristics of portal-based interventions that would best support deprescribing for PWD and develop pragmatic workflows.

High-Risk Medications in Persons Living With Dementia: A Randomized Clinical Trial

Importance

Individuals with Alzheimer disease (AD) and Alzheimer disease-related dementias (ADRD) may be at increased risk for adverse outcomes relating to inappropriate prescribing of certain high-risk medications, including antipsychotics, sedative-hypnotics, and strong anticholinergic agents.

Objective

To evaluate the effect of a patient/caregiver and prescriber-mailed educational intervention on potentially inappropriate prescribing to patients with AD or ADRD.

Design, Setting, and Participants

This prospective, open-label, pragmatic randomized clinical trial, embedded in 2 large national health plans, was conducted from April 2022 to June 2023. The trial included patients with AD or ADRD and use of any of 3 drug classes targeted for deprescribing (antipsychotics, sedative-hypnotics, or strong anticholinergics).

Interventions

Patients were randomized to 1 of 3 arms: (1) a mailing of educational materials specific to the medication targeted for deprescribing to both the patient and their prescribing clinician; (2) a mailing to the prescribing clinician only; or (3) a usual care arm.

Main Outcomes and Measures

Analysis was performed using a modified intention-to-treat approach. The primary study outcome was the dispensing of the medication targeted for deprescribing during a 6-month study observation period. Secondary outcomes included changes in medication-specific mean daily dose and health service utilization.

Results

Among 12 787 patients included in the modified intention-to-treat analysis, 8742 (68.4%) were female, and the mean (SD) age was 77.3 (9.4) years. The cumulative incidence of being dispensed a medication targeted for deprescribing was 76.7% (95% CI, 75.4-78.0) in the patient and prescriber mailing group, 77.9% (95% CI, 76.5-79.1) in the prescriber mailing only group, and 77.5% (95% CI, 76.2-78.8) in the usual care group. Hazard ratios were 0.99 (95% CI, 0.94-1.04) for the patient and prescriber group and 1.00 (95% CI, 0.96-1.06) for the prescriber only group compared with the usual care group. There were no differences between the groups for secondary outcomes.

Conclusions and Relevance

These findings suggest medication-specific educational mailings targeting patients with AD or ADRD and their clinicians are not effective in reducing the use of high-risk medications.

Impact of Hospitalizations on Problematic Medication Use Among Community-Dwelling Persons With Dementia

BACKGROUND

Hospitalizations are frequently disruptive for persons with dementia (PWD) in part due to the use of potentially problematic medications for complications such as delirium, pain, and insomnia. We sought to determine the impact of hospitalizations on problematic medication prescribing in the months following hospitalization.

METHODS

We included community-dwelling PWD in the Health and Retirement Study aged ≥66 with a hospitalization from 2008 to 2018. We characterized problematic medications as medications that negatively affect cognition (strongly anticholinergics/sedative-hypnotics), medications from the 2019 Beers criteria, and medications from STOPP-V2. To capture durable changes, we compared problematic medications 4 weeks prehospitalization (baseline) to 4 months posthospitalization period. We used a generalized linear mixed model with Poisson distribution adjusting for age, sex, comorbidity count, prehospital chronic medications, and timepoint.

RESULTS

Among 1 475 PWD, 504 had a qualifying hospitalization (median age 84 (IQR = 79-90), 66% female, 17% Black). There was a small increase in problematic medications from the baseline to posthospitalization timepoint that did not reach statistical significance (adjusted mean 1.28 vs 1.40, difference 0.12 (95% CI -0.03, 0.26), p = .12). Results were consistent across medication domains and certain subgroups. In one prespecified subgroup, individuals on <5 prehospital chronic medications showed a greater increase in posthospital problematic medications compared with those on ≥5 medications (p = .04 for interaction, mean increase from baseline to posthospitalization of 0.25 for those with <5 medications (95% CI 0.05, 0.44) vs. 0.06 (95% CI -0.12, 0.25) for those with ≥5 medications).

CONCLUSIONS

Hospitalizations had a small, nonstatistically significant effect on longer-term problematic medication use among PWD.

The effect of deprescribing interventions on mortality and health outcomes in older people: An updated systematic review and meta-analysis

AIMS

Previous systematic reviews suggest that deprescribing may improve survival, particularly in frail older people. Evidence is rapidly accumulating, suggesting a need for an updated review of the literature.

METHODS

We updated a 2016 systematic review and meta-analysis to include studies published from inception to 26 April 2024 from specified databases. Studies in which older people had at least one medication deprescribed were included and grouped by study designs and targeted medications. The risk of bias was assessed using the Cochrane tool and the Newcastle-Ottawa tool. Odds ratios (OR) or mean differences were calculated as the effect measures using either the Mantel-Haenszel or generic inverse-variance method with fixed- or random-effects meta-analyses. The primary outcome was mortality. Secondary outcomes were adverse drug withdrawal events, physical health, cognitive function, quality of life and effect on medication regimen. Subgroup analyses were performed based on age and intervention types.

RESULTS

A total of 259 studies (reported in 286 papers) were included in this updated review. Deprescribing polypharmacy did not result in a significant reduction in mortality in both randomized (OR 0.96, 95% confidence interval [CI] 0.84-1.09) and non-randomized studies (OR 0.70, 95% CI 0.36-1.38). Further subgroup analyses of randomized studies on deprescribing polypharmacy demonstrated a significant reduction in mortality in the young old (aged 65-79) (OR 0.71, 95% CI 0.51-0.99) and when patient-specific interventions were applied (OR 0.79, 95% CI 0.63-0.99).

CONCLUSIONS

Deprescribing can be achieved with potentially important benefits in terms of improved survival, particularly when patient-specific interventions are applied and initiated early in the young old.

Co-Designing a Consult Patient Decision Aid for Continuation Versus Deprescribing Cholinesterase Inhibitors in People Living with Dementia

BACKGROUND AND OBJECTIVE

As dementia progresses, people living with dementia may take high-risk, unnecessary, or ineffective medicines. Cholinesterase inhibitors (ChEIs) may have benefit in some people with dementia; however, up to one third are continued when no longer necessary or safe. Our aim was to co-design a consult patient decision aid (CPtDA) to support shared decision making between healthcare professionals and consumers about continuing or deprescribing ChEIs.

METHODS

A systematic process was employed to design and test the CPtDA prototype. First, a steering group composed of healthcare professionals and a consumer representative was assembled. Guided by the International Patient Decision Aids Standards, the steering group defined the CPtDA's purpose, scope, and target audience and drafted the prototype for further testing. Interviews with consumers and healthcare professionals were conducted to gain feedback on the content, format, structure, comprehensibility and usability of the CPtDA prototype.

RESULTS

After the steering group developed the CPtDA prototype, interviews were conducted with 11 consumers and six healthcare professionals. The content and format of the decision aid were improved iteratively over three rounds after consolidating the feedback at each round. The main changes included rewording the purpose of the decision aid and simplifying its layout and format. Participants reported that the decision aid is comprehensible and may be useful in practice.

CONCLUSIONS

Limited available resources guide shared decision making about deprescribing. This study resulted in a co-designed and alpha-tested CPtDA for people living with dementia and carers to help them review the ongoing need for their ChEIs. Further research is needed to explore using the CPtDA in practice to support people living with dementia and their carers engage in the shared decision-making process about continuing or deprescribing their ChEIs. Our co-designed CPtDA could help people living with dementia and their carers review their goals of care alongside their healthcare professional. This may prompt conversations about appropriately using ChEIs and increase the uptake of deprescribing.

Effect of antihypertensive deprescribing on hospitalisation and mortality: long-term follow-up of the OPTiMISE randomised controlled trial

BACKGROUND

Deprescribing of antihypertensive medications is recommended for some older patients with low blood pressure and frailty. The OPTiMISE trial showed that this deprescribing can be achieved with no differences in blood pressure control at 3 months compared with usual care. We aimed to examine effects of deprescribing on longer-term hospitalisation and mortality.

METHODS

This randomised controlled trial enrolled participants from 69 general practices across central and southern England. Participants aged 80 years or older, with systolic blood pressure less than 150 mm Hg and who were receiving two or more antihypertensive medications, were randomly assigned (1:1) to antihypertensive medication reduction (removal of one antihypertensive) or usual care. General practitioners and participants were aware of the treatment allocation following randomisation but individuals responsible for analysing the data were masked to the treatment allocation throughout the study. Participants were followed up via their primary and secondary care electronic health records at least 3 years after randomisation. The primary outcome was time to all-cause hospitalisation or mortality. Intention-to-treat analyses were done using Cox regression modelling. A per-protocol analysis of the primary outcome was also done, excluding participants from the intervention group who did not reduce treatment or who had medication reinstated during the initial trial 12-week follow-up period. This study is registered with the European Union Drug Regulating Authorities Clinical Trials Database (EudraCT2016-004236-38) and the ISRCTN Registry (ISRCTN97503221).

FINDINGS

Between March 20, 2017, and Sept 30, 2018, a total of 569 participants were randomly assigned. Of these, 564 (99%; intervention=280; control=284) were followed up for a median of 4·0 years (IQR 3·7-4·3). Participants had a mean age of 84·8 years (SD 3·4) at baseline and 273 (48%) were women. Medication reduction was sustained in 109 participants at follow-up (51% of the 213 participants alive in the intervention group). Participants in the intervention group had a larger reduction in antihypertensives than the control group (adjusted mean difference -0·35 drugs [95% CI -0·52 to -0·18]). Overall, 202 (72%) participants in the intervention group and 218 (77%) participants in the control group experienced hospitalisation or mortality during follow-up (adjusted hazard ratio [aHR] 0·93 [95% CI 0·76 to 1·12]). There was some evidence that the proportion of participants experiencing the primary outcome in the per-protocol population was lower in the intervention group (aHR 0·80 [0·64 to 1·00]).

INTERPRETATION

Half of participants sustained medication reduction with no evidence of an increase in all-cause hospitalisation or mortality. These findings suggest that an antihypertensive deprescribing intervention might be safe for people aged 80 years or older with controlled blood pressure taking two or more antihypertensives.

Association Between Patient Portal Activities and End-of-Life Outcomes Among Deceased Patients in the Last 12 Months of Life

Objective: The objective of this study was to examine the association between portal use and end-of-life (EOL) outcomes in the last year of life. Methods: A retrospective cohort (n = 6,517) study at Kaiser Permanente Colorado among adults with serious illness deceased between January 1, 2016, and June 30, 2019. Portal use was categorized into engagement types: no use, nonactive, active without a provider, and active with a provider. EOL outcomes were hospitalizations in the month before death, last-year advance directive completion, and hospice use. Association between EOL outcomes and levels of portal use was assessed using χ2 statistics and generalized linear models. Results: Higher portal engagement types were associated with higher rates of hospitalizations (p = 0.0492), advance directive completion (p = 0.0226), and hospice use (p = 0.0070). Conclusion: Portal use in the last year of life was associated with increases in a poor EOL outcome, hospitalizations, and beneficial EOL outcomes, advance directives, and hospice care.

Medication Optimization Protocol Efficacy for Geriatric Inpatients: A Randomized Clinical Trial

Importance

There is currently no consensus on clinically effective interventions for polypharmacy among older inpatients.

Objective

To evaluate the effect of multidisciplinary team-based medication optimization on survival, unscheduled hospital visits, and rehospitalization in older inpatients with polypharmacy.

Design, Setting, and Participants

This open-label randomized clinical trial was conducted at 8 internal medicine inpatient wards within a community hospital in Japan. Participants included medical inpatients 65 years or older who were receiving 5 or more regular medications. Enrollment took place between May 21, 2019, and March 14, 2022. Statistical analysis was performed from September 2023 to May 2024.

Intervention

The participants were randomly assigned to receive either an intervention for medication optimization or usual care including medication reconciliation. The intervention consisted of a medication review using the STOPP (Screening Tool of Older Persons' Prescriptions)/START (Screening Tool to Alert to Right Treatment) criteria, followed by a medication optimization proposal for participants and their attending physicians developed by a multidisciplinary team. On discharge, the medication optimization summary was sent to patients' primary care physicians and community pharmacists.

Main Outcomes and Measures

The primary outcome was a composite of death, unscheduled hospital visits, and rehospitalization within 12 months. Secondary outcomes included the number of prescribed medications, falls, and adverse events.

Results

Between May 21, 2019, and March 14, 2022, 442 participants (mean [SD] age, 81.8 [7.1] years; 223 [50.5%] women) were randomly assigned to the intervention (n = 215) and usual care (n = 227). The intervention group had a significantly lower percentage of patients with 1 or more potentially inappropriate medications than the usual care group at discharge (26.2% vs 33.0%; adjusted odds ratio [OR], 0.56 [95% CI, 0.33-0.94]; P = .03), at 6 months (27.7% vs 37.5%; adjusted OR, 0.50 [95% CI, 0.29-0.86]; P = .01), and at 12 months (26.7% vs 37.4%; adjusted OR, 0.45 [95% CI, 0.25-0.80]; P = .007). The primary composite outcome occurred in 106 participants (49.3%) in the intervention group and 117 (51.5%) in the usual care group (stratified hazard ratio, 0.98 [95% CI, 0.75-1.27]). Adverse events were similar between each group (123 [57.2%] in the intervention group and 135 [59.5%] in the usual care group).

Conclusions and Relevance

In this randomized clinical trial of older inpatients with polypharmacy, the multidisciplinary deprescribing intervention did not reduce death, unscheduled hospital visits, or rehospitalization within 12 months. The intervention was effective in reducing the number of medications with no significant adverse effects on clinical outcomes, even among older inpatients with polypharmacy.

Pharmacist-led telehealth deprescribing for people living with dementia and polypharmacy in primary care: A pilot study

BACKGROUND

People living with dementia (PLWD) have complex medication regimens, exposing them to increased risk of harm. Pragmatic deprescribing strategies that align with patient-care partner goals are needed.

METHODS

A pilot study of a pharmacist-led intervention to optimize medications with patient-care partner priorities, ran May 2021-2022 at two health systems. PLWD with ≥7 medications in primary care and a care partner were enrolled. After an introductory mailing, dyads were randomized to a pharmacist telehealth intervention immediately (intervention) or delayed by 3 months (control). Feasibility outcomes were enrollment, intervention completion, pharmacist time, and primary care provider (PCP) acceptance of recommendations. To refine pragmatic data collection protocols, we assessed the Medication Regimen Complexity Index (MRCI; primary efficacy outcome) and the Family Caregiver Medication Administration Hassles Scale (FCMAHS).

RESULTS

69 dyads enrolled; 27 of 34 (79%) randomized to intervention and 28 of 35 (80%) randomized to control completed the intervention. Most visits (93%) took more than 20 min and required multiple follow-up interactions (62%). PCPs responded to 82% of the pharmacists' first messages and agreed with 98% of recommendations. At 3 months, 22 (81%) patients in the intervention and 14 (50%) in the control had ≥1 medication discontinued; 21 (78%) and 12 (43%), respectively, had ≥1 new medication added. The mean number of medications decreased by 0.6 (3.4) in the intervention and 0.2 (1.7) in the control, reflecting a non-clinically meaningful 1.0 (±12.4) point reduction in the MRCI among intervention patients and a 1.2 (±12.9) point increase among control. FCMAHS scores decreased by 3.3 (±18.8) points in the intervention and 2.5 (±14.4) points in the control.

CONCLUSION

Though complex, pharmacist-led telehealth deprescribing is feasible and may reduce medication burden in PLWD. To align with patient-care partner goals, pharmacists recommended deprescribing and prescribing. If scalable, such interventions may optimize goal-concordant care for PLWD.

Deprescribing interventions in older adults: An overview of systematic reviews

OBJECTIVE

The growing deprescribing field is challenged by a lack of consensus around evidence and knowledge gaps. The objective of this overview of systematic reviews was to summarize the review evidence for deprescribing interventions in older adults.

METHODS

11 databases were searched from 1st January 2005 to 16th March 2023 to identify systematic reviews. We summarized and synthesized the results in two steps. Step 1 summarized results reported by the included reviews (including meta-analyses). Step 2 involved a narrative synthesis of review results by outcome. Outcomes included medication-related outcomes (e.g., medication reduction, medication appropriateness) or twelve other outcomes (e.g., mortality, adverse events). We summarized outcomes according to subgroups (patient characteristics, intervention type and setting) when direct comparisons were available within the reviews. The quality of included reviews was assessed using A MeaSurement Tool to Assess systematic Reviews 2 (AMSTAR 2).

RESULTS

We retrieved 3,228 unique citations and assessed 135 full-text articles for eligibility. Forty-eight reviews (encompassing 17 meta-analyses) were included. Thirty-one of the 48 reviews had a general deprescribing focus, 16 focused on specific medication classes or therapeutic categories and one included both. Twelve of 17 reviews meta-analyzed medication-related outcomes (33 outcomes: 25 favored the intervention, 7 found no difference, 1 favored the comparison). The narrative synthesis indicated that most interventions resulted in some evidence of medication reduction while for other outcomes we found primarily no evidence of an effect. Results were mixed for adverse events and few reviews reported adverse drug withdrawal events. Limited information was available for people with dementia, frailty and multimorbidity. All but one review scored low or critically low on quality assessment.

CONCLUSION

Deprescribing interventions likely resulted in medication reduction but evidence on other outcomes, in particular relating to adverse events, or in vulnerable subgroups or settings was limited. Future research should focus on designing studies powered to examine harms, patient-reported outcomes, and effects on vulnerable subgroups.

Deprescribing in older adults with polypharmacy

Polypharmacy is common in older adults and is associated with adverse drug events, cognitive and functional impairment, increased healthcare costs, and increased risk of frailty, falls, hospitalizations, and mortality. Many barriers exist to deprescribing, but increased efforts have been made to develop and implement deprescribing interventions that overcome them. This narrative review describes intervention components and summarizes findings from published randomized controlled trials that have tested deprescribing interventions in older adults with polypharmacy, as well as reports on ongoing trials, guidelines, and resources that can be used to facilitate deprescribing. Most interventions were medication reviews in primary care settings, and many contained components such as shared decision making and/or a focus on patient care priorities, training for healthcare professionals, patient facing education materials, and involvement of family members, representing great heterogeneity in interventions addressing polypharmacy in older adults. Just over half of study interventions were found to perform better than usual care in at least one of their primary outcomes, and most study interventions were assessed over 12 months or less.

Insights into designing educational materials for persons living with dementia: a focus group study

BACKGROUND

Persons living with dementia (PLWD) may experience communication difficulties that impact their ability to process written and pictorial information. Patient-facing education may help promote discontinuation of potentially inappropriate medications for older adults without dementia, but it is unclear how to adapt this approach for PLWD. Our objective was to solicit feedback from PLWD and their care partners to gain insights into the design of PLWD-facing deprescribing intervention materials and PLWD-facing education material more broadly.

METHODS

We conducted 3 successive focus groups with PLWD aged ≥ 50 (n = 12) and their care partners (n = 10) between December 2022 and February 2023. Focus groups were recorded and transcripts were analyzed for overarching themes.

RESULTS

We identified 5 key themes: [1] Use images and language consistent with how PLWD perceive themselves; [2] Avoid content that might heighten fear or anxiety; [3] Use straightforward delivery with simple language and images; [4] Direct recipients to additional information; make the next step easy; and [5] Deliver material directly to the PLWD.

CONCLUSION

PLWD-facing educational material should be addressed directly to PLWD, using plain, non-threatening and accessible language with clean, straightforward formatting.

Implementation considerations of deprescribing interventions: A scoping review

Over half of older adults experience polypharmacy, including medications that may be inappropriate or unnecessary. Deprescribing, which is the process of discontinuing or reducing inappropriate and/or unnecessary medications, is an effective way to reduce polypharmacy. This review summarizes (1) the process of deprescribing and conceptual models and tools that have been developed to facilitate deprescribing, (2) barriers, enablers, and factors associated with deprescribing, and (3) characteristics of deprescribing interventions in completed trials, as well as (4) implementation considerations for deprescribing in routine practice. In conceptual models of deprescribing, multilevel factors of the patient, clinician, and health-care system are all related to the efficacy of deprescribing. Numerous tools have been developed for clinicians to facilitate deprescribing, yet most require substantial time and, thus, may be difficult to implement during routine health-care encounters. Multiple deprescribing interventions have been evaluated, which mostly include one or more of the following components: patient education, medication review, identification of deprescribing targets, and patient and/or provider communication about high-risk medications. Yet, there has been limited consideration of implementation factors in prior deprescribing interventions, especially with regard to the personnel and resources in existing health-care systems and the feasibility of incorporating components of deprescribing interventions into the routine care processes of clinicians. Future trials require a more balanced consideration of both effectiveness and implementation when designing deprescribing interventions.

Developing a PRogram to Educate and Sensitize Caregivers to Reduce the Inappropriate Prescription Burden in the Elderly with Alzheimer's Disease (D-PRESCRIBE-AD): Trial protocol and rationale of an open-label pragmatic, prospective randomized controlled trial

CONTEXT

Potentially inappropriate prescribing of medications in older adults, particular those with dementia, can lead to adverse drug events including falls and fractures, worsening cognitive impairment, emergency department visits, and hospitalizations. Educational mailings from health plans to patients and their providers to encourage deprescribing conversations may represent an effective, low-cost, "light touch", approach to reducing the burden of potentially inappropriate prescription use in older adults with dementia.

OBJECTIVES

The objective of the Developing a PRogram to Educate and Sensitize Caregivers to Reduce the Inappropriate Prescription Burden in Elderly with Alzheimer's Disease (D-PRESCRIBE-AD) trial is to evaluate the effect of a health plan based multi-faceted educational outreach intervention to community dwelling patients with dementia who are currently prescribed sedative/hypnotics, antipsychotics, or strong anticholinergics.

METHODS

The D-PRESCRIBE-AD is an open-label pragmatic, prospective randomized controlled trial (RCT) comparing three arms: 1) educational mailing to both the health plan patient and their prescribing physician (patient plus physician arm, n = 4814); 2) educational mailing to prescribing physician only (physician only arm, n = 4814); and 3) usual care (n = 4814) among patients with dementia enrolled in two large United States based health plans. The primary outcome is the absence of any dispensing of the targeted potentially inappropriate prescription during the 6-month study observation period after a 3-month black out period following the mailing. Secondary outcomes include dose-reduction, polypharmacy, healthcare utilization, mortality and therapeutic switching within targeted drug classes.

CONCLUSION

This large pragmatic RCT will contribute to the evidence base on promoting deprescribing of potentially inappropriate medications among older adults with dementia. If successful, such light touch, inexpensive and highly scalable interventions have the potential to reduce the burden of potentially inappropriate prescribing for patients with dementia.

Polypharmacy and Deprescribing in Older Adults

Older adults commonly end up on many medications. Deprescribing is an important part of individualizing care for older adults. It is an opportunity to discuss treatment options and revisit medications that may not have been reassessed in many years. A large evidence base exists in the field, suggesting that deprescribing is feasible and safe, though questions remain about the potential clinical benefits. Deprescribing research faces a myriad of challenges, such as identifying and employing the optimal outcome measures. Further, there is uncertainty about which deprescribing approaches are likely to be most effective and in what contexts. Evidence on barriers and facilitators to deprescribing has underscored how deprescribing in routine clinical practice can be complex and challenging. Thus, finding practical, sustainable ways to implement deprescribing is a priority for future research in the field.

Introducing a pharmacist-led transmural care program to reduce drug-related problems in orthogeriatric patients: a prospective interventional study

BACKGROUND

Orthogeriatric patients have an increased risk for complications due to underlying comorbidities, chronic drug therapy and frequent treatment changes during hospitalization. The clinical pharmacist (CP) plays a key role in transmural communication concerning polypharmacy to improve continuity of care by the general practitioner (GP) after discharge. In this study, a pharmacist-led transmural care program, tailored to orthogeriatric patients, was evaluated to reduce drug related problems (DRPs) after discharge.

METHODS

An interventional study was performed (pre-period: 1/10/2021-31/12/2021; post-period: 1/01/2022-31/03/2022). Patients (≥ 65 years) from the orthopedic department were included. The pre-group received usual care, the post-group received the pharmacist-led transmural care program. The DRP reduction rate one month after discharge was calculated. Associated factors for the DRP reduction rate were determined in a multiple linear regression analysis. The GP acceptance rate was determined for the proposed interventions, as well as their clinical impact using the Clinical, Economic and Organizational (CLEO) tool. Readmissions one month after discharge were evaluated.

RESULTS

Overall, 127 patients were included (control n = 61, intervention n = 66). The DRP reduction rate was statistically significantly higher in the intervention group compared to the control group (p < 0.001). The pharmacist's intervention was associated with an increased DRP reduction rate (+ 1.750, 95% confidence interval 1.222-2.278). In total, 141 interventions were suggested by the CP, of which 71% were accepted one month after discharge. In both periods, four patients were readmitted one month after discharge. 58% of the interventions had a clinical impact (≥ 2 C level using the CLEO-tool) according to the geriatrician and for the CP it was 45%, indicating that they had the potential to avoid patient harm.

CONCLUSIONS

The pharmacist-led transmural care program significantly reduced DRPs in geriatric patients from the orthopedic department one month after discharge. The transmural communication with GPs resulted in a high acceptance rate of the proposed interventions.

Influence of Potentially Inappropriate Medication Use on Older Australians' Admission to Emergency Department Short Stay

Older people in the emergency department (ED) often pose complex medical challenges, with a significant prevalence of polypharmacy and potentially inappropriate medicines (PIMs) in Australia. A retrospective analysis of 200 consecutive patients aged over 65 years admitted to the emergency short stay unit (ESSU) aimed to identify polypharmacy (five or more regular medications), assess PIM prevalence, and explore the link between pre-admission PIMs and ESSU admissions. STOPP/START version 2 criteria were used for the PIM assessment, with an expert panel categorizing associated risks. Polypharmacy was observed in 161 patients (80.5%), who were older (mean age 82 versus 76 years) and took more regular medications (median 9 versus 3). One hundred and eighty-five (92.5%) patients had at least one PIM, 81 patients (40.5%) had STOPP PIMs, and 177 patients (88.5%) had START omissions. Polypharmacy significantly correlated with STOPP PIM (OR 4.8; 95%CI: 1.90-12.1), and for each additional medication the adjusted odds of having a STOPP PIM increased by 1.20 (95%CI: 1.11-1.28). Nineteen admissions (9.5%) were attributed to one or more PIMs (total 21 PIMs). Of these PIMs, the expert panel rated eight (38%) as high risk, five (24%) as moderate risk, and eight (38%) as low risk for causing hospital admission. The most common PIMs were benzodiazepines, accounting for 14 cases (73.6%). Older ESSU-admitted patients commonly presented with polypharmacy and PIMs, potentially contributing to their admission.

Evaluating the Safety of an Educational Deprescribing Intervention: Lessons from the Optimize Trial

BACKGROUND

Patients, family members, and clinicians express concerns about potential adverse drug withdrawal events (ADWEs) following medication discontinuation or fears of upsetting a stable medical equilibrium as key barriers to deprescribing. Currently, there are limited methods to pragmatically assess the safety of deprescribing and ascertain ADWEs. We report the methods and results of safety monitoring for the OPTIMIZE trial of deprescribing education for patients, family members, and clinicians.

METHODS

This was a pragmatic cluster randomized trial with multivariable Poisson regression comparing outcome rates between study arms. We conducted clinical record review and adjudication of sampled records to assess potential causal relationships between medication discontinuation and outcomes. This study included adults aged 65+ with dementia or mild cognitive impairment, one or more additional chronic conditions, and prescribed 5+ chronic medications. The intervention included an educational brochure on deprescribing that was mailed to patients prior to primary care visits, a clinician notification about individual brochure mailings, and an educational tip sheets was provided monthly to primary care clinicians. The outcomes of the safety monitoring were rates of hospitalizations and mortality during the 4 months following brochure mailings and results of record review and adjudication. The adjudication process was conducted throughout the trial and included classifications: likely, possibly, and unlikely.

RESULTS

There was a total of 3012 (1433 intervention and 1579 control) participants. There were 420 total hospitalizations involving 269 (18.8%) people in the intervention versus 517 total hospitalizations involving 317 (20.1%) people in the control groups. Adjusted risk ratios comparing intervention to control groups were 0.92 [95% confidence interval (CI) 0.72, 1.16] for hospitalization and 1.19 (95% CI 0.67, 2.11) for mortality. Both groups had zero deaths "likely" attributed to a medication change prior to the event. A total of 3 out of 30 (10%) intervention group hospitalizations and 7 out of 35 (20%) control group hospitalizations were considered "likely" due to a medication change.

CONCLUSIONS

Population-based deprescribing education is safe in the older adult population with cognitive impairment in our study. Pragmatic methods for safety monitoring are needed to further inform deprescribing interventions.

Implementation of interprofessional quality circles on deprescribing in Swiss nursing homes: an observational study

BACKGROUND

Polypharmacy and potentially inappropriate medications (PIMs) are still frequent among older adults in nursing homes. Deprescribing is an intervention that has been shown to be effective in reducing their use. However, the implementation of deprescribing in clinical practice has not yet been widely evaluated. The Quality Circle Deprescribing Module (QC-DeMo) intervention has been trialled through an effectiveness-implementation hybrid type 2 design. The intervention consists of a quality circle workshop session between healthcare professionals HCPs (physicians, nurses, and pharmacists) within a nursing home, in which they define a consensus to deprescribe specific PIMs classes. The aim of this study was to evaluate the implementation of the QC-DeMo intervention in nursing homes.

METHODS

This observational study focuses on the implementation part of the QC-DeMo trial. Implementation was based on the Framework for Implementation of Pharmacy Services (FISpH). Questionnaires at baseline and follow-up were used to evaluate reach, adoption, implementation effectiveness, fidelity, implementation, maintenance and the implementation strategies. Other data were collected from the QC-DeMo trial and routine data collected as part of the integrated pharmacy service where the QC-Demo trial was embedded. Implementation strategies included training of pharmacists, integration of the intervention into an existing quality circle dynamic and definition of tailored strategies to operationalise the consensus by each nursing home.

RESULTS

The QC-DeMo intervention was successfully implemented in 26 nursing homes in terms of reach, fidelity, adoption, implementation and implementation effectiveness. However, the intervention was found to be implemented with low maintenance as none of the nursing homes repeated the intervention after the trial. Implementation strategies were well received by HCPs: training was adequate according to pharmacists. Pre-existing quality circle dynamic facilitated interprofessional collaboration as involvement and support of each HCP was rated as high. HCPs recognized a specific and important role for each HCP in the deprescribing process. The most relevant tailored strategies to implement the consensus defined by each nursing home were identification of the patients by the pharmacist and a systematic review of medication's patients.

CONCLUSIONS

The implementation of a Quality Circle on Deprescribing is feasible but its maintenance in practice remains challenging. This study explores multiple implementation outcomes to better inform future implementation efforts of these types of interventions.

Stakeholder Perspectives on Factors Related to Deprescribing Potentially Inappropriate Medications in Older Adults Receiving Dialysis

BACKGROUND

Potentially inappropriate medications, or medications that generally carry more risk of harm than benefit in older adults, are commonly prescribed to older adults receiving dialysis. Deprescribing, a systematic approach to reducing or stopping a medication, is a potential solution to limit potentially inappropriate medications use. Our objective was to identify clinicians and patient perspectives on factors related to deprescribing to inform design of a deprescribing program for dialysis clinics.

METHODS

We conducted rapid qualitative analysis of semistructured interviews and focus groups with clinicians (dialysis clinicians, primary care providers, and pharmacists) and patients (adults receiving hemodialysis aged 65 years or older and those aged 55-64 years who were prefrail or frail) from March 2019 to December 2020.

RESULTS

We interviewed 76 participants (53 clinicians [eight focus groups and 11 interviews] and 23 patients). Among clinicians, 24 worked in dialysis clinics, 18 worked in primary care, and 11 were pharmacists. Among patients, 13 (56%) were aged 65 years or older, 14 (61%) were Black race, and 16 (70%) reported taking at least one potentially inappropriate medication. We identified four themes (and corresponding subthemes) of contextual factors related to deprescribing potentially inappropriate medications: ( 1 ) system-level barriers to deprescribing (limited electronic medical record interoperability, time constraints and competing priorities), ( 2 ) undefined comanagement among clinicians (unclear role delineation, clinician caution about prescriber boundaries), ( 3 ) limited knowledge about potentially inappropriate medications (knowledge limitations among clinicians and patients), and ( 4 ) patients prioritize symptom control over potential harm (clinicians expect resistance to deprescribing, patient weigh risks and benefits).

CONCLUSIONS

Challenges to integration of deprescribing into dialysis clinics included siloed health systems, time constraints, comanagement behaviors, and clinician and patient knowledge and attitudes toward deprescribing.

Medication misuse and overuse in community-dwelling persons with dementia

BACKGROUND

Persons with dementia (PWD) have high rates of polypharmacy. While previous studies have examined specific types of problematic medication use in PWD, we sought to characterize a broad spectrum of medication misuse and overuse among community-dwelling PWD.

METHODS

We included community-dwelling adults aged ≥66 in the Health and Retirement Study from 2008 to 2018 linked to Medicare and classified as having dementia using a validated algorithm. Medication usage was ascertained over the 1-year prior to an HRS interview date. Potentially problematic medications were identified by: (1) medication overuse including over-aggressive treatment of diabetes/hypertension (e.g., insulin/sulfonylurea with hemoglobin A1c < 7.5%) and medications inappropriate near end of life based on STOPPFrail and (2) medication misuse including medications that negatively affect cognition and medications from 2019 Beers and STOPP Version 2 criteria. To contextualize, we compared medication use to people without dementia through a propensity-matched cohort by age, sex, comorbidities, and interview year. We applied survey weights to make our results nationally representative.

RESULTS

Among 1441 PWD, median age was 84 (interquartile range = 78-89), 67% female, and 14% Black. Overall, 73% of PWD were prescribed ≥1 potentially problematic medication with a mean of 2.09 per individual in the prior year. This was notable across several domains, including 41% prescribed ≥1 medication that negatively affects cognition. Frequently problematic medications included proton pump inhibitors (PPIs), non-steroidal anti-inflammatory drugs (NSAIDs), opioids, antihypertensives, and antidiabetic agents. Problematic medication use was higher among PWD compared to those without dementia with 73% versus 67% prescribed ≥1 problematic medication (p = 0.002) and mean of 2.09 versus 1.62 (p < 0.001), respectively.

CONCLUSION

Community-dwelling PWD frequently receive problematic medications across multiple domains and at higher frequencies compared to those without dementia. Deprescribing efforts for PWD should focus not only on potentially harmful central nervous system-active medications but also on other classes such as PPIs and NSAIDs.

Telepharmacy Model of Care

PURPOSE

This study assessed the feasibility of the Telepharmacy Model of Care, a medication review and deprescribing model for use in older adults, with innovations in cognitive and functional evaluation, in telemedicine delivery, and in the use of a pharmacy technician.

METHODS

This retrospective medical record review/abstraction analyzed (from March 1, 2022, to December 31, 2022) data from US veteran participants in a pilot implementation (April 13, 2021, to May 20, 2022) of the Telepharmacy Model of Care at the Veterans Affairs Ann Arbor Healthcare System (Ann Arbor, Michigan). The project team assessed and made recommendations about multiple factors in medication management: medication list accuracy; safety of medications and their combinations; older adults' cognition, health literacy, and physical abilities and impairments in self-managing medications; and caregivers' ability to compensate for those impairments.

FINDINGS

The pilot included 60 US veterans (mean age, 75 years [range, 59-93 years]; 97% were men). Overall, participants were successful in using telemedicine (98%). Encounters required 30 to 45 minutes for the visit and 20 minutes for follow-up and documentation (P = 0.14 pharmacist vs pharmacy technician). The median number of medications per patient was 18. A total of 57% of patients had four or more medication-related discrepancies; fewer patients experienced medication-adherence problems, drug-drug interactions, problematic medication combinations, and untreated/undertreated conditions. Using the Safe Medication Algorithm for Older Adults tool, 35% were identified as taking a Red Flag medication (contraindicated in older adults), and 74%, a High Risk medication (eg, an anticoagulant). A total of 37% had cognitive and health literacy impairments, and 45%, physical impairments, interfering with the ability to self-manage medications. Recommendations on deprescribing were made in 98% of patients.

IMPLICATION

The telemedicine-based and pharmacist/pharmacy technician-delivered model was a feasible method for addressing comprehensive medication review and deprescribing in these cognitively and functionally impaired US veterans.

Changes in the Use of Long-Term Medications Following Incident Dementia Diagnosis

Importance

Dementia is a life-altering diagnosis that may affect medication safety and goals for chronic disease management.

Objective

To examine changes in medication use following an incident dementia diagnosis among community-dwelling older adults.

Design, Setting, and Participants

In this cohort study of adults aged 67 years or older enrolled in traditional Medicare and Medicare Part D, patients with incident dementia diagnosed between January 2012 and December 2018 were matched to control patients based on demographics, geographic location, and baseline medication count. The index date was defined as the date of first dementia diagnosis or, for controls, the date of the closest office visit. Data were analyzed from August 2021 to June 2023.

Exposure

Incident dementia diagnosis.

Main Outcomes and Measures

The main outcomes were overall medication counts and use of cardiometabolic, central nervous system (CNS)-active, and anticholinergic medications. A comparative time-series analysis was conducted to examine quarterly changes in medication use in the year before through the year following the index date.

Results

The study included 266 675 adults with incident dementia and 266 675 control adults; in both groups, 65.1% were aged 80 years or older (mean [SD] age, 82.2 [7.1] years) and 67.8% were female. At baseline, patients with incident dementia were more likely than controls to use CNS-active medications (54.32% vs 48.39%) and anticholinergic medications (17.79% vs 15.96%) and less likely to use most cardiometabolic medications (eg, diabetes medications, 31.19% vs 36.45%). Immediately following the index date, the cohort with dementia had a greater increase in mean number of medications used (0.41 vs -0.06; difference, 0.46 [95% CI, 0.27-0.66]) and in the proportion of patients using CNS-active medications (absolute change, 3.44% vs 0.79%; difference, 2.65% [95% CI, 0.85%-4.45%]) owing to an increased use of antipsychotics, antidepressants, and antiepileptics. The cohort with dementia also had a modestly greater decline in use of anticholinergic medications (quarterly change in use, -0.53% vs -0.21%; difference, -0.32% [95% CI, -0.55% to -0.08%]) and most cardiometabolic medications (eg, quarterly change in antihypertensive use: -0.84% vs -0.40%; difference, -0.44% [95% CI, -0.64% to -0.25%]). One year after diagnosis, 75.2% of the cohort with dementia were using 5 or more medications (2.8% increase).

Conclusions and Relevance

In this cohort study of Medicare Part D beneficiaries, following an incident dementia diagnosis, patients were more likely to initiate CNS-active medications and modestly more likely to discontinue cardiometabolic and anticholinergic medications compared with the control group. These findings suggest missed opportunities to reduce burdensome polypharmacy by deprescribing long-term medications with high safety risks or limited likelihood of benefit or that may be associated with impaired cognition.

Patient Polypharmacy use Following a Multi-Disciplinary Dementia Care Program in a Memory Clinic: A Retrospective Cohort Study

Introduction

Dementia increases the risk of polypharmacy. Timely detection and optimal care can stabilize or delay the progression of dementia symptoms, which may in turn reduce polypharmacy. We aimed to evaluate the change in polypharmacy use among memory clinic patients living with dementia who participated in a dementia care program compared to those who did not. We hypothesized that patients in the dementia care program would reduce their use of polypharmacy compared to those who were not in standard care.

Methods

We retrospectively analyzed data extracted from electronic medical records from a university memory clinic. Data from a total of 381 patients were included in the study: 107 in the program and 274 matched patients in standard care. We used adjusted odds ratios to assess the association between enrollment in the program and polypharmacy use at follow-up (five or more concurrent medications), controlling for baseline polypharmacy use and stratified polypharmacy use by prescription and over-the-counter (OTC).

Results

The two groups did not differ in the use of five or more overall and prescription medications at follow-up, controlling for the use of five or more of the respective medications at baseline and covariates. Being in the program was associated with a three-fold lower odds of using five or more OTC medications at follow-up (adjusted odds ratio = 0.30; p <0.001; 95% Confidence interval = 0.15-0.58) after controlling for using five or more OTC medications at baseline and covariates.

Conclusions

Dementia care may reduce polypharmacy of OTC medications, potentially reducing risky drug-drug interactions. More research is needed to infer causality and understand how to reduce prescription medication polypharmacy.

What makes a multidisciplinary medication review and deprescribing intervention for older people work well in primary care? A realist review and synthesis

BACKGROUND

A third of older people take five or more regular medications (polypharmacy). Conducting medication reviews in primary care is key to identify and reduce/ stop inappropriate medications (deprescribing). Recent recommendations for effective deprescribing include shared-decision making and a multidisciplinary approach. Our aim was to understand when, why, and how interventions for medication review and deprescribing in primary care involving multidisciplinary teams (MDTs) work (or do not work) for older people.

METHODS

A realist synthesis following the Realist And Meta-narrative Evidence Syntheses: Evolving Standards guidelines was completed. A scoping literature review informed the generation of an initial programme theory. Systematic searches of different databases were conducted, and documents screened for eligibility, with data extracted based on a Context, Mechanisms, Outcome (CMO) configuration to develop further our programme theory. Documents were appraised based on assessments of relevance and rigour. A Stakeholder consultation with 26 primary care health care professionals (HCPs), 10 patients and three informal carers was conducted to test and refine the programme theory. Data synthesis was underpinned by Normalisation Process Theory to identify key mechanisms to enhance the implementation of MDT medication review and deprescribing in primary care.

FINDINGS

A total of 2821 abstracts and 175 full-text documents were assessed for eligibility, with 28 included. Analysis of documents alongside stakeholder consultation outlined 33 CMO configurations categorised under four themes: 1) HCPs roles, responsibilities and relationships; 2) HCPs training and education; 3) the format and process of the medication review 4) involvement and education of patients and informal carers. A number of key mechanisms were identified including clearly defined roles and good communication between MDT members, integration of pharmacists in the team, simulation-based training or team building training, targeting high-risk patients, using deprescribing tools and drawing on expertise of other HCPs (e.g., nurses and frailty practitioners), involving patents and carers in the process, starting with 'quick wins', offering deprescribing as 'drug holidays', and ensuring appropriate and tailored follow-up plans that allow continuity of care and management.

CONCLUSION

We identified key mechanisms that could inform the design of future interventions and services that successfully embed deprescribing in primary care.

Optimising prescribing in older adults with multimorbidity and polypharmacy in primary care (OPTICA): cluster randomised clinical trial

OBJECTIVE

To study the effects of a primary care medication review intervention centred around an electronic clinical decision support system (eCDSS) on appropriateness of medication and the number of prescribing omissions in older adults with multimorbidity and polypharmacy compared with a discussion about medication in line with usual care.

DESIGN

Cluster randomised clinical trial.

SETTING

Swiss primary care, between December 2018 and February 2021.

PARTICIPANTS

Eligible patients were ≥65 years of age with three or more chronic conditions and five or more long term medications.

INTERVENTION

The intervention to optimise pharmacotherapy centred around an eCDSS was conducted by general practitioners, followed by shared decision making between general practitioners and patients, and was compared with a discussion about medication in line with usual care between patients and general practitioners.

MAIN OUTCOME MEASURES

Primary outcomes were improvement in the Medication Appropriateness Index (MAI) and the Assessment of Underutilisation (AOU) at 12 months. Secondary outcomes included number of medications, falls, fractures, and quality of life.

RESULTS

In 43 general practitioner clusters, 323 patients were recruited (median age 77 (interquartile range 73-83) years; 45% (n=146) women). Twenty one general practitioners with 160 patients were assigned to the intervention group and 22 general practitioners with 163 patients to the control group. On average, one recommendation to stop or start a medication was reported to be implemented per patient. At 12 months, the results of the intention-to-treat analysis of the improvement in appropriateness of medication (odds ratio 1.05, 95% confidence interval 0.59 to 1.87) and the number of prescribing omissions (0.90, 0.41 to 1.96) were inconclusive. The same was the case for the per protocol analysis. No clear evidence was found for a difference in safety outcomes at the 12 month follow-up, but fewer safety events were reported in the intervention group than in the control group at six and 12 months.

CONCLUSIONS

In this randomised trial of general practitioners and older adults, the results were inconclusive as to whether the medication review intervention centred around the use of an eCDSS led to an improvement in appropriateness of medication or a reduction in prescribing omissions at 12 months compared with a discussion about medication in line with usual care. Nevertheless, the intervention could be safely delivered without causing any harm to patients.

Perspectives on deprescribing in palliative care

INTRODUCTION

Pharmacotherapy plays a critical role in the delivery of high-quality palliative care, but the intersection of palliative care and deprescribing has received little attention.

AREAS COVERED

We conducted a scoping review of English language articles using PubMed to identify relevant publications between 1 January 2000 to 31 July 2022 using search terms of deprescribing, palliative care, end of life, and hospice. We summarize current definitions and developments in palliative care and deprescribing from both clinical and research perspectives. We highlight key challenges and outline proposed solutions and needed research.

EXPERT OPINION

The future of deprescribing in palliative care requires the development and adoption of individualized approaches to medication management, including a reconsidered approach to communication about deprescribing. Evidence from high-quality clinical outcomes studies is lacking, and the field needs new approaches to coordination of care delivery. This review article will be of interest to both clinical and research-based pharmacists, physicians, and nurses interested in improving care for patients with serious illness.

Effect of collaborative dementia care on potentially inappropriate medication use: Outcomes from the Care Ecosystem randomized clinical trial

INTRODUCTION

Potentially inappropriate medications (PIMs) cause adverse events and death. We evaluate the Care Ecosystem (CE) collaborative dementia care program on medication use among community-dwelling persons living with dementia (PLWD).

METHODS

Secondary analysis of a randomized clinical trial (RCT) comparing CE to usual care (UC) on changes in PIMs, over 12 months between March 2015 and May 2020. Secondary outcomes included change in number of medications, clinically relevant PIMs, and anti-dementia medications.

RESULTS

Of 804 PLWD, N = 490 had complete medication data. The CE resulted in significantly fewer PIMs compared to UC (-0.35; 95% CI, -0.49 to -0.20; P < 0.0001). Number needed to prevent an increase in 1 PIM was 3. Total medications, PIMs for dementia or cognitive impairment, CNS-active PIMs, anticholinergics, benzodiazepines, and opioids were also fewer. Anti-dementia medication regimens were modified more frequently.

CONCLUSION

The CE medication review intervention embedded in collaborative dementia care optimized medication use among PLWD.

HIGHLIGHTS

Compared to usual care (UC), the Care Ecosystem (CE) medication review intervention prevented increases in potentially inappropriate medications (PIMs). Use of anticholinergics, benzodiazepines, and opioids were significantly reduced, with a trend for antipsychotics. Anti-dementia medications were adjusted more frequently. The CE medication review intervention embedded in collaborative dementia care optimized medication use.

Catalyzing dementia care through the learning health system and consumer health information technology

To advance care for persons with Alzheimer's disease and related dementias (ADRD), real-world health system effectiveness research must actively engage those affected to understand what works, for whom, in what setting, and for how long-an agenda central to learning health system (LHS) principles. This perspective discusses how emerging payment models, quality improvement initiatives, and population health strategies present opportunities to embed best practice principles of ADRD care within the LHS. We discuss how stakeholder engagement in an ADRD LHS when embedding, adapting, and refining prototypes can ensure that products are viable when implemented. Finally, we highlight the promise of consumer-oriented health information technologies in supporting persons living with ADRD and their care partners and delivering embedded ADRD interventions at scale. We aim to stimulate progress toward sustainable infrastructure paired with person- and family-facing innovations that catalyze broader transformation of ADRD care.

Intervention design in cognitively impaired populations-Lessons learned from the OPTIMIZE deprescribing pragmatic trial

BACKGROUND

Polypharmacy is common in older adults with cognitive impairment and multiple chronic conditions, increasing risks of adverse drug events, hospitalization, and death. Deprescribing, the process of reducing or stopping potentially inappropriate medications, may improve outcomes. The OPTIMIZE pragmatic trial examined whether educating and activating patients, family members and clinicians about deprescribing reduces number of chronic medications and potentially inappropriate medications. Acceptability and challenges of intervention delivery in cognitively impaired older adults are not well understood.

METHODS

We explored mechanisms of intervention implementation through post hoc qualitative interviews and surveys with stakeholder groups of 15 patients, 7 caregivers, and 28 clinicians. We assessed the context in which the intervention was delivered, its implementation, and mechanisms of impact.

RESULTS

Acceptance of the intervention was affected by contextual factors including cognition, prior knowledge of deprescribing, communication, and time constraints. All stakeholder groups endorsed the acceptability, importance, and delivery of the intervention. Positive mechanisms of impact included patients scheduling specific appointments to discuss deprescribing and providers being prompted to consider deprescribing. Recollection of intervention materials was inconsistent but most likely shortly after intervention delivery. Short visit times remained the largest provider barrier to deprescribing.

CONCLUSIONS

Our work identifies key learnings in intervention delivery that can guide future scaling of deprescribing interventions in this population. We highlight the critical roles of timing and repetition in intervention delivery to cognitively impaired populations and the barrier posed by short consultation times. The acceptability of the intervention to patients and family members highlights the potential to incorporate deprescribing education into routine clinical practice and expand proven interventions to other vulnerable populations.

Family Conferences to Facilitate Deprescribing in Older Outpatients With Frailty and With Polypharmacy: The COFRAIL Cluster Randomized Trial

Importance

For older adults with frailty syndrome, reducing polypharmacy may have utility as a safety-promoting treatment option.

Objective

To investigate the effects of family conferences on medication and clinical outcomes in community-dwelling older adults with frailty receiving polypharmacy.

Design, Setting, and Participants

This cluster randomized clinical trial was conducted from April 30, 2019, to June 30, 221, at 110 primary care practices in Germany. The study included community-dwelling adults aged 70 years or older with frailty syndrome, daily use of at least 5 different medications, a life expectancy of at least 6 months, and no moderate or severe dementia.

Interventions

General practitioners (GPs) in the intervention group received 3 training sessions on family conferences, a deprescribing guideline, and a toolkit with relevant nonpharmacologic interventions. Three GP-led family conferences for shared decision-making involving the participants and family caregivers and/or nursing services were subsequently held per patient at home over a period of 9 months. Patients in the control group received care as usual.

Main Outcomes and Measures

The primary outcome was the number of hospitalizations within 12 months, as assessed by nurses during home visits or telephone interviews. Secondary outcomes included the number of medications, the number of European Union list of the number of potentially inappropriate medication (EU[7]-PIM) for older people, and geriatric assessment parameters. Both per-protocol and intention-to-treat analyses were conducted.

Results

The baseline assessment included 521 individuals (356 women [68.3%]; mean [SD] age, 83.5 [6.17] years). The intention-to-treat analysis with 510 patients showed no significant difference in the adjusted mean (SD) number of hospitalizations between the intervention group (0.98 [1.72]) and the control group (0.99 [1.53]). In the per-protocol analysis including 385 individuals, the mean (SD) number of medications decreased from 8.98 (3.56) to 8.11 (3.21) at 6 months and to 8.49 (3.63) at 12 months in the intervention group and from 9.24 (3.44) to 9.32 (3.59) at 6 months and to 9.16 (3.42) at 12 months in the control group, with a statistically significant difference at 6 months in the mixed-effect Poisson regression model (P = .001). After 6 months, the mean (SD) number of EU(7)-PIMs was significantly lower in the intervention group (1.30 [1.05]) than in the control group (1.71 [1.25]; P = .04). There was no significant difference in the mean number of EU(7)-PIMs after 12 months.

Conclusions and Relevance

In this cluster randomized clinical trial with older adults taking 5 or more medications, the intervention consisting of GP-led family conferences did not achieve sustainable effects in reducing the number of hospitalizations or the number of medications and EU(7)-PIMs after 12 months.

Deprescribing Medications Among Older Adults From End of Hospitalization Through Postacute Care: A Shed-MEDS Randomized Clinical Trial

Importance

Deprescribing is a promising approach to addressing the burden of polypharmacy. Few studies have initiated comprehensive deprescribing in the hospital setting among older patients requiring ongoing care in a postacute care (PAC) facility.

Objective

To evaluate the efficacy of a patient-centered deprescribing intervention among hospitalized older adults transitioning or being discharged to a PAC facility.

Design, Setting, and Participants

This randomized clinical trial of the Shed-MEDS (Best Possible Medication History, Evaluate, Deprescribing Recommendations, and Synthesis) deprescribing intervention was conducted between March 2016 and October 2020. Patients who were admitted to an academic medical center and discharged to 1 of 22 PAC facilities affiliated with the medical center were recruited. Patients who were 50 years or older and had 5 or more prehospital medications were enrolled and randomized 1:1 to the intervention group or control group. Patients who were non-English speaking, were unhoused, were long-stay residents of nursing homes, or had less than 6 months of life expectancy were excluded. An intention-to-treat approach was used.

Interventions

The intervention group received the Shed-MEDS intervention, which consisted of a pharmacist- or nurse practitioner-led comprehensive medication review, patient or surrogate-approved deprescribing recommendations, and deprescribing actions that were initiated in the hospital and continued throughout the PAC facility stay. The control group received usual care at the hospital and PAC facility.

Main Outcomes and Measures

The primary outcome was the total medication count at hospital discharge and PAC facility discharge, with follow-up assessments during the 90-day period after PAC facility discharge. Secondary outcomes included the total number of potentially inappropriate medications at each time point, the Drug Burden Index, and adverse events.

Results

A total of 372 participants (mean [SD] age, 76.2 [10.7] years; 229 females [62%]) were randomized to the intervention or control groups. Of these participants, 284 were included in the intention-to-treat analysis (142 in the intervention group and 142 in the control group). Overall, there was a statistically significant treatment effect, with patients in the intervention group taking a mean of 14% fewer medications at PAC facility discharge (mean ratio, 0.86; 95% CI, 0.80-0.93; P < .001) and 15% fewer medications at the 90-day follow-up (mean ratio, 0.85; 95% CI, 0.78-0.92; P < .001) compared with the control group. The intervention additionally reduced patient exposure to potentially inappropriate medications and Drug Burden Index. Adverse drug event rates were similar between the intervention and control groups (hazard ratio, 0.83; 95% CI, 0.52-1.30).

Conclusions and Relevance

Results of this trial showed that the Shed-MEDS patient-centered deprescribing intervention was safe and effective in reducing the total medication burden at PAC facility discharge and 90 days after discharge. Future studies are needed to examine the effect of this intervention on patient-reported and long-term clinical outcomes.

Willingness of older people living with dementia and mild cognitive impairment and their caregivers to have medications deprescribed

BACKGROUND

people living with cognitive impairment commonly take multiple medications including potentially inappropriate medications (PIMs), which puts them at risk of medication related harms.

AIMS

to explore willingness to have a medication deprescribed of older people living with cognitive impairment (dementia or mild cognitive impairment) and multiple chronic conditions and assess the relationship between willingness, patient characteristics and belief about medications.

METHODS

cross-sectional study using results from the revised Patients' Attitudes Towards Deprescribing questionnaire (rPATDcog) collected as baseline data in the OPTIMIZE study, a pragmatic, cluster-randomised trial educating patients and clinicians about deprescribing. Eligible participants were 65+, diagnosed with dementia or mild cognitive impairment, and prescribed at least five-long-term medications.

RESULTS

the questionnaire was mailed to 1,409 intervention patients and 553 (39%) were returned and included in analysis. Participants had a mean age of 80.1 (SD 7.4) and 52.4% were female. About 78.5% (431/549) of participants said that they would be willing to have one of their medications stopped if their doctor said it was possible. Willingness to deprescribe was negatively associated with getting stressed when changes are made and with previously having a bad experience with stopping a medication (P < 0.001 for both).

CONCLUSION

most older people living with cognitive impairment are willing to deprescribe. Addressing previous bad experiences with stopping a medication and stress when changes are made to medications may be key points to discuss during deprescribing conversations.

Management of psychotropic medications in adults with intellectual disability: a scoping review

BACKGROUND/OBJECTIVE(S)

Psychotropic medications are commonly prescribed among adults with intellectual disability, often in the absence of a psychiatric diagnosis. The aim of this scoping review is to provide an overview of the extent, range, and nature of the available research on medication use and practices and medication management in people with intellectual disability taking psychotropic medications for behaviours that challenge.

MATERIALS AND METHODS

A scoping review of research studies (qualitative, quantitative, and mixed design) and Grey Literature (English) was carried out. Databases included: Ovid MEDLINE, Embase, CINAHL, JBI Evidence Synthesis, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, PsycINFO, and Scopus. A three-step search strategy was followed, with results screened by two independent reviewers. Data was extracted independently by two reviewers using a data extraction tool with results mapped and presented using a narrative form supported by tables and diagrams to the research questions.

RESULTS

Following the removal of duplicates, records were screened, full texts assessed, and 49 studies were included. Medication outcomes included reduced repetitive, stereotypic, and/or aggressive behaviours. High dosing/prescribing in the setting of an absent/unclear clinical indication was associated with worsening of symptoms for which psychotropics were prescribed. While psychotropics had a role in managing behaviours that challenge, reducing or discontinuing psychotropics is sometimes warranted. Study designs were frequently pragmatic resulting in small sample sizes and heterogeneous cohorts receiving different doses and combinations of medications. Access to multidisciplinary teams, guidelines, medication reviews, staff training, and enhanced roles for carers in decision-making were warranted to optimize psychotropic use.

CONCLUSIONS

These findings can inform prescribing interventions and highlight the need for timely and comprehensive patient outcome data, especially on long-term use of high doses of psychotropics and what happens when reduce or stop prescribing these doses.KEY MESSAGESPsychotropic medications are frequently prescribed for people with intellectual disabilities, often at high doses and these medications are associated with both positive and negative patient outcomes.Work to rationalize psychotropic use has been reported with interventions aiming to reduce polypharmacy or deprescribe a single psychotropic medicine. These interventions had mixed success and risk of relapse was documented in some studies.Limitations in sample size and heterogenous patient cohorts make it challenging to understand the risks and benefits associated with reducing or stopping psychotropic medicines.Patient, carer, and clinician partnerships are critical to advance medication management.

Can clinician champions reduce potentially inappropriate medications in people living with dementia? Study protocol for a cluster randomized trial

BACKGROUND

For people living with dementia (PLWD) the overuse of potentially inappropriate medications (PIMs) remains a persistent problem. De-prescribing trials in the elderly have mixed results. Clinician champions may be uniquely suited to lead efforts to address this challenge. Here we describe the study protocol for a 24-month embedded pragmatic cluster-randomized clinical trial within two accountable care organizations (ACOs) of such a clinician champion intervention. The specific aims are to (1) assess the effectiveness of a clinician champion on de-implementing PIMs in PLWD, (2) determine if the intervention is associated with a reduction in emergency department (ED) visits and hospitalizations attributed to a fall, and (3) examine five implementation outcomes: appropriateness, feasibility, fidelity, penetration, and equity.

METHODS/DESIGN

Two ACOs agreed to participate: United States Medical Management (USMM) and Oschner Health System. The unit of randomization will be the primary care clinic. A clinician champion will be recruited from each of the intervention clinics to participate in a 6-month training program and then work with clinicians and staff in their clinic for 12 months to reduce the use of PIMs in their PLWD population. For aims 1 and 2, Medicare claims data will be used to assess outcomes. The outcome for aim #1 will be medication possession rates per quarter, for the three therapeutic classes of PIMs among patients with dementia in intervention clinics versus control clinics. For aim #2, we will assess the incidence of falls using a previously validated algorithm. For both aims 1 and 2, we will construct hierarchical models with time period observations nested within patient using generalized estimating equations (GEE) with robust standard errors. The key variable of interest will be the treatment indicator assigned based on practice. For aim #3, we will conduct qualitative thematic analysis of documentation by the clinician champions in their project workbooks to evaluate the five implementation outcomes.

DISCUSSION

This embedded pragmatic trial will add to our existing knowledge regarding the effectiveness of a clinician champion strategy to de-prescribe potentially inappropriate medication among patients with dementia as well as its appropriateness, feasibility, fidelity, penetration, and equity.

Potential Targets for Deprescribing in Medically Complex Older Adults with Suspected Cognitive Impairment

Deprescribing may be particularly beneficial in patients with medical complexity and suspected cognitive impairment (CI). We describe central nervous system (CNS) medication use and side effects in this population and explore the relationship between anticholinergic burden and sleep. We conducted a cross-sectional analysis of baseline data from a pilot randomized-controlled trial in older adult veterans with medical complexity (Care Assessment Need score > 90), and suspected CI (Telephone Interview for Cognitive Status score 20−31). CNS medication classes included antipsychotics, benzodiazepines, H2-receptor antagonists, hypnotics, opioids, and skeletal muscle relaxants. We also coded anticholinergic-active medications according to their Anticholinergic Cognitive Burden (ACB) score. Other measures included self-reported medication side effects and the Pittsburgh Sleep Quality Index (PSQI). ACB association with sleep (PSQI) was examined using adjusted linear regression. In this sample (N = 40), the mean number of prescribed CNS medications was 2.2 (SD 1.5), 65% experienced ≥ 1 side effect, and 50% had an ACB score ≥ 3 (high anticholinergic exposure). The ACB score ≥ 3 compared to ACB < 3 was not significantly associated with PSQI scores (avg diff in score = −0.1, 95% CI −2.1, 1.8). Although results did not demonstrate a clear relationship with worsened sleep, significant side effects and anticholinergic burden support the deprescribing need in this population.
