A Collaborative Deprescribing Intervention in a Subacute Medical Outpatient Clinic: A Pilot Randomized Controlled Trial

Systematic review and meta-analysis on the effectiveness of multidisciplinary interventions to address polypharmacy in community-dwelling older adults

Interventions to address polypharmacy in community-dwelling older adults often focus on medication-related outcomes. The aim was to explore the impact of multidisciplinary interventions to manage polypharmacy on clinical outcomes for community-dwelling older adults. This systematic review and meta-analysis included randomized controlled trials (RCTs) on interventions by at least a pharmacist and a physician, indexed in MEDLINE, EMBASE or CENTRAL up to January 2023. Evidence certainty was assessed using the GRADE approach. Seventeen RCTs were included. Fifteen were rated as 'high' risk of bias. No relevant benefits were found in functional and cognitive status (primary outcomes), falls, mortality, quality of life, patient satisfaction, hospital admissions, emergency department or primary care visits. Interventions reduced medication costs, improved medication appropriateness (odds ratio [OR] 0.39), reduced number of medications (mean difference [MD] -0.57), resolved medication-related problems (MD -0.45), and improved medication adherence (relative risk [RR] 1.14). There was a low or very low certainty of the evidence for most outcomes. Multidisciplinary interventions to address polypharmacy appear effective in improving multiple dimensions of medication use. However, evidence for corresponding improvements in functional or cognitive status is scarce. New efficient models of multidisciplinary interventions to address polypharmacy impacting clinical outcomes should be explored.

Deprescribing in a multimorbid older adult: A case vignette study among community pharmacists and primary care physicians

Collaborative deprescribing can include pharmacists' medication review with identification and suggestion of potential deprescribing targets to physicians. Case vignettes can be a valuable method for researching variations in clinical decision making, especially in settings unaccustomed to newer clinical approaches such as deprescribing. This study aimed to explore if pharmacists can identify deprescribing targets and if physicians would accept pharmacist's deprescribing rationales. A cross-sectional study was performed using an online case vignette based on a real-life elderly patient. Pharmacists were asked to indicate which medicines they would recommend deprescribing, alongside a rationale. Physicians were asked to state their acceptance of the proposed pharmacist's deprescribing suggestion. Pharmacists gave 1275 deprescribing rationales, and most were given for deprescribing opioids, NSAID and diuretics. Physicians would accept rationales to deprescribe a median of 10 medicines, while pharmacist would recommend deprescribing a median of six medicines. Most difference lays in deprescribing of preventative medicines. Healthcare providers share agreement on deprescribing targets, but pharmacists show hesitancies in making recommendations that could hamper potential collaboration. Action is needed to improve pharmacists' skills in recognizing deprescribing targets and confidence in making suggestions, which could lead to opening of possibilities for joint patient care.

The role of pharmacists in deprescribing benzodiazepines: A scoping review

Background

Polypharmacy can increase the risk of adverse drug events, hospitalisation, and unnecessary healthcare costs. Evidence indicates that discontinuing certain medications, such as benzodiazepines, can improve health outcomes, by resolving adverse drug effects. This scoping review aims to explore the pharmacists' role in deprescribing benzodiazepines.

Method

A scoping review has been conducted to distinguish and map the literature, discover research gaps, and focus on targeted areas for future studies and research. A systematic search strategy was conducted to identify relevant studies from PubMed, Medline, and EMBASE databases. The eligibility criteria involved studies that focused on the role of pharmacists in benzodiazepine deprescribing, quantitative and qualitative studies conducted in humans, full-text articles published in English.

Results

Twenty studies were identified, revealing three themes: 1) pharmacists' involvement in benzodiazepine deprescribing, 2) the impact of their involvement, and 3) obstacles impeding the process. Pharmacists involved in deprescribing procedures, mainly through completing medication reviews, collaborative work with other healthcare providers, and education. Pharmacists' involvement in benzodiazepine deprescribing intervention led to better health and economic outcomes. Withdrawal symptoms after medication discontinuation, dependence on medication, and lack of time and guidelines were identified in the literature as barriers to deprescribing.

Conclusion

Pharmacists' involvement in deprescribing benzodiazepines is crucial for optimizing medication therapy. This scoping review examines the pharmacists' role in benzodiazepine deprescribing. The findings contribute to enhancing healthcare outcomes and guiding future research in this area.

Interventions to improve the appropriate use of polypharmacy for older people

BACKGROUND

Inappropriate polypharmacy is a particular concern in older people and is associated with negative health outcomes. Choosing the best interventions to improve appropriate polypharmacy is a priority, so that many medicines may be used to achieve better clinical outcomes for patients. This is the third update of this Cochrane Review.

OBJECTIVES

To assess the effects of interventions, alone or in combination, in improving the appropriate use of polypharmacy and reducing medication-related problems in older people.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase, CINAHL and two trials registers up until 13 January 2021, together with handsearching of reference lists to identify additional studies. We ran updated searches in February 2023 and have added potentially eligible studies to 'Characteristics of studies awaiting classification'.

SELECTION CRITERIA

For this update, we included randomised trials only. Eligible studies described interventions affecting prescribing aimed at improving appropriate polypharmacy (four or more medicines) in people aged 65 years and older, which used a validated tool to assess prescribing appropriateness. These tools can be classified as either implicit tools (judgement-based/based on expert professional judgement) or explicit tools (criterion-based, comprising lists of drugs to be avoided in older people).

DATA COLLECTION AND ANALYSIS

Four review authors independently reviewed abstracts of eligible studies, and two authors extracted data and assessed the risk of bias of the included studies. We pooled study-specific estimates, and used a random-effects model to yield summary estimates of effect and 95% confidence intervals (CIs). We assessed the overall certainty of evidence for each outcome using the GRADE approach.

MAIN RESULTS

We identified 38 studies, which includes an additional 10 in this update. The included studies consisted of 24 randomised trials and 14 cluster-randomised trials. Thirty-six studies examined complex, multi-faceted interventions of pharmaceutical care (i.e. the responsible provision of medicines to improve patients' outcomes), in a variety of settings. Interventions were delivered by healthcare professionals such as general physicians, pharmacists, nurses and geriatricians, and most were conducted in high-income countries. Assessments using the Cochrane risk of bias tool found that there was a high and/or unclear risk of bias across a number of domains. Based on the GRADE approach, the overall certainty of evidence for each pooled outcome ranged from low to very low. It is uncertain whether pharmaceutical care improves medication appropriateness (as measured by an implicit tool) (mean difference (MD) -5.66, 95% confidence interval (CI) -9.26 to -2.06; I2 = 97%; 8 studies, 947 participants; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the number of potentially inappropriate medications (PIMs) (standardised mean difference (SMD) -0.19, 95% CI -0.34 to -0.05; I2 = 67%; 9 studies, 2404 participants; very low-certainty evidence). It is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PIM (risk ratio (RR) 0.81, 95% CI 0.68 to 0.98; I2 = 84%; 13 studies, 4534 participants; very low-certainty evidence). Pharmaceutical care may slightly reduce the number of potential prescribing omissions (PPOs) (SMD -0.48, 95% CI -1.05 to 0.09; I2 = 92%; 3 studies, 691 participants; low-certainty evidence), however it must be noted that this effect estimate is based on only three studies, which had serious limitations in terms of risk of bias. Likewise, it is uncertain whether pharmaceutical care reduces the proportion of patients with one or more PPO (RR 0.50, 95% CI 0.27 to 0.91; I2 = 95%; 7 studies, 2765 participants; very low-certainty evidence). Pharmaceutical care may make little or no difference to hospital admissions (data not pooled; 14 studies, 4797 participants; low-certainty evidence). Pharmaceutical care may make little or no difference to quality of life (data not pooled; 16 studies, 7458 participants; low-certainty evidence). Medication-related problems were reported in 10 studies (6740 participants) using different terms (e.g. adverse drug reactions, drug-drug interactions). No consistent intervention effect on medication-related problems was noted across studies. This also applied to studies examining adherence to medication (nine studies, 3848 participants).

AUTHORS' CONCLUSIONS

It is unclear whether interventions to improve appropriate polypharmacy resulted in clinically significant improvement. Since the last update of this review in 2018, there appears to have been an increase in the number of studies seeking to address potential prescribing omissions and more interventions being delivered by multidisciplinary teams.

Cognitive and functional trajectories in geriatric outpatients after a pharmacologic multidisciplinary intervention: A study protocol

BACKGROUND

Polypharmacy is a common condition among older adults and is associated with adverse drug reactions and health outcomes, including falls, functional and cognitive impairment, and frailty.

METHODS

A prospective observational study will be conducted on older adults with polypharmacy. The aim is to assess the impact of a specialized outpatient clinic focused on pharmacotherapy optimization recently integrated into daily clinical practice in a Spanish public tertiary teaching hospital on patients' functional and cognitive abilities. Patients who attend a first consultation and meet inclusion criteria (≥75 years old, have a life expectancy≥3 months, and polypharmacy (≥5 prescribed medications) will be invited to participate in the study, until reach a calculated sample size of 104 participants. Patients will be excluded if they are enrolled in a clinical trial related to medication or in the event of a no-show or cancellation of the appointment at the first visit. Participants will receive usual care: a first consultation including multidisciplinary pharmacological optimization in the context of a CGA and subsequent face-to-face and/or telephone follow-up (∼3 and ∼6 months). The primary endpoint will be the functional (Barthel index) and cognitive change in capacities (IPCR - Índice de Incapacidad psíquica de la Cruz Roja). Secondary endpoints include medication changes, changes in patients' quality of life, rate of falling, and use of healthcare resources.

DISCUSSION

We expect that the close collaboration between professionals from different disciplines working together will be an effective strategy to improve the functional and cognitive abilities of older adults.

Outcomes in deprescribing implementation trials and compliance with expert recommendations: a systematic review

BACKGROUND

Deprescribing, defined as discontinuing or reducing the dose of medications that are no longer needed or for which the risks outweigh the benefits is a way to reduce polypharmacy. In 2022, the US Deprescribing Research Network (USDeN) published recommendations concerning the measurement of outcomes for deprescribing intervention studies. The objectives of this systematic review were to identify the outcome categories used in deprescribing intervention trials and to relate them to the previously published recommendations.

METHODS

We searched MEDLINE, Embase, PsychInfo, and the Cochrane library from January 2012 through January 2022. Studies were included if they were randomized controlled trials evaluating a deprescribing intervention. After data extraction, outcomes were categorized by type: medication outcomes, clinical outcomes, system outcomes, implementation outcomes, and other outcomes based on the previously published recommendations.

RESULTS

Thirty-six studies were included. The majority of studies focused on older adults in nursing homes and targeted inappropriate medications or polypharmacy. In 20 studies, the intervention was a medication review; in seven studies, the intervention was educational or informative; and three studies based their intervention on motivational interviewing or patient empowerment. Thirty-one studies presented a medication outcome (primary outcome in 26 studies), 25 a clinical outcome, 18 a system outcome, and seven an implementation outcome. Only three studies presented all four types of outcomes, and 10 studies presented three types of outcomes.

CONCLUSIONS

This review provides an update on the implementation of gold standard deprescribing studies in clinical practice. Implementation outcomes need to be developed and specified to facilitate the implementation of these practices on a larger scale and clinical outcome need to be prioritized. Finally, this review provides new elements for future real-life deprescribing studies.

Reducing inappropriate polypharmacy for older patients at specialist outpatient clinics: a systematic review

OBJECTIVE

Polypharmacy is associated with negative clinical consequences. The efficacy of deprescribing interventions within medical specialist outpatient clinics remains unclear. Here, we reviewed the research on the effectiveness of deprescribing interventions implemented within specialist outpatient clinics for patients ≥ 60 years.

METHODS

Systematic searches of key databases were undertaken for studies published between January 1990 and October 2021. The diverse nature of the study designs made it unsuitable for pooling for meta-analysis, thus, a narrative review was conducted and presented in both text and tabular formats. The primary outcome for review was that intervention resulted in a change in medication load (either total number of medications or appropriateness of medication). Secondary outcomes were the maintenance of deprescription and clinical benefits. Methodological quality of the publications was assessed using the revised Cochrane risk-of-bias tools.

RESULTS

Nineteen studies with a total of 10,914 participants were included for review. These included geriatric outpatient clinics, oncology/hematology clinics, hemodialysis clinics, and designated polypharmacy/multimorbidity clinics. Four randomized controlled trials (RCTs) reported statistically significant reductions in medication load with intervention; however, all studies had a high risk of bias. The inclusion of a pharmacist in outpatient clinics aims to increase deprescribing, however, the current evidence is mainly restricted to prospective and pilot studies. The data on secondary outcomes were very limited and highly variable.

CONCLUSIONS

Specialist outpatient clinics may provide valuable settings for implementing deprescribing interventions. The addition of a multidisciplinary team including a pharmacist and the use of validated medication assessment tools appear to be enablers. Further research is warranted.

Optimization of the Danish National Electronic Prescribing System to Improve Patient Safety: Development of a User-Friendly Prototype of the Digital Platform Shared Medication Record

This study uses a participatory design to develop a user-friendly prototype of the current Danish digital platform, Shared Medication Record (SMR), to improve patient safety and minimize medication errors for patients with multimorbidity. A fundamental challenge for medication prescribing is the lack of access to an accurate medication list, which impairs effective communication between healthcare professionals and increases the risk of medication errors. We used a participatory design to identify the major problems with the existing SMR and develop a prototype for a redesigned SMR that addresses these problems. We argue that this prototype will improve communication between healthcare providers, promote patient involvement in their own care, and ultimately reduce medication errors related to the SMR. Moreover, we argue that the participatory design with its emphasis on user involvement and design iterations is a strong approach when designing IT solutions for complex problems in healthcare.

Recent Updates on Risk and Management Plans Associated with Polypharmacy in Older Population

The concept of polypharmacy encompasses adverse drug reactions and non-adherence factors in elderly individuals. It also leads to the increased use of healthcare services and negative health outcomes. The problem is further alleviated by the odds of potentially inappropriate medications (PIM), which lead to the development of drug-related problems. Since polypharmacy is more commonly observed in the elderly population, urgency is required to introduce operative protocols for preventing and managing this problem. The family medicine model of care can be associated with favorable illness outcomes regarding satisfaction with consultation, treatment adherence, self-management behaviors, adherence to medical advice, and healthcare utilization. Hence, interventions built on family medicine models can provide significant support in improving the outcomes of the older population and their quality of life. In this regard, the authors have taken up the task of explaining the accessible resources which can be availed to improve the application of health care services in the field of geriatric medicine.

Development and Validation of Comprehensive Healthcare Providers' Opinions, Preferences, and Attitudes towards Deprescribing (CHOPPED Questionnaire)

Successful implementation of deprescribing requires exploring healthcare professionals’ opinions, preferences, and attitudes towards deprescribing. The aim of this study was to develop and validate the questionnaire exploring healthcare providers’ opinions preferences and attitudes towards deprescribing (CHOPPED questionnaire). This was a cross-sectional on-line survey. A comprehensive 58-item questionnaire, in two versions (for pharmacists and physicians), was developed through an extensive literature review and interviews with experts. The questionnaire was validated, and its reliability was assessed through data collected from 356 pharmacists and 109 physicians. Exploratory factor analysis was performed, and 37- and 35-item questionnaires were developed. Ten factors were identified: knowledge, awareness, patient barriers and facilitators, competencies barriers and facilitators, collaboration barriers and facilitators, and healthcare system barriers and facilitators. The CHOPPED tool has satisfactory face, content (CVR > 0.62) (content validity ratio), construct, and criterion validity. The reliability statistics of all factors in both versions was acceptable with Cronbach’s alpha > 0.6. Test−retest reliability analysis showed that gamma rank correlations of total factor scores were strong and very strong (between 0.519 and 0.938). The CHOPPED tool can be used as a valid and reliable tool to explore healthcare providers’ opinions and attitudes toward discontinuing medications in the primary care setting in Croatia.
