The benefits and harms of deprescribing

'Recommendations for deprescribing of medication in the last phase of life: an international Delphi study'

CONTEXT

Medications may become inappropriate for patients in the last phase of life and may even compromise their quality of life.

OBJECTIVE

To find consensus on recommendations regarding deprescribing of medications for adult patients with a life expectancy of six months or less.

METHODS

Experts working in palliative care or other relevant disciplines were asked to participate in this international Delphi study. Existing tools for deprescribing of medication in the last phase of life were integrated in a list of 42 recommendations regarding potential deprescription of various medication types. In two Delphi rounds, experts were asked to rate their agreement with each recommendation on a 5-point Likert-scale (strongly agree - strongly disagree). Recommendations were accepted, if at least 70% of the experts (strongly) agreed, the interquartile range (IQR) was one or less, and less than 10% strongly disagreed.

RESULTS

47 experts from 10 countries participated (response rate 53%). In most cases (76%), consensus was reached on deprescribing recommendations for patients with a life expectancy of six months or less. The highest level of consensus was reached for recommendations on the deprescription of diuretics in case of decreasing fluid intake or increasing fluid loss, lipid modifying agents if prescribed for primary prevention, and vitamin K antagonists and direct oral anticoagulants in case of high bleeding risk.

CONCLUSION

A high level of consensus was reached on recommendations on potential deprescription of several medications for patients with a life expectancy of six months or less.

Polypharmacy in chronic kidney disease: Health outcomes & pharmacy-based strategies to mitigate inappropriate polypharmacy

The rising prevalence of comorbidities in an increasingly aging population has sparked a reciprocal rise in polypharmacy. Patients with chronic kidney disease (CKD) have a greater burden of polypharmacy due to the comorbidities and complications associated with their disease. Polypharmacy in CKD patients has been linked to myriad direct and indirect costs for patients and the society at large. Pharmacists are uniquely positioned within the healthcare team to streamline polypharmacy management in the setting of CKD. In this article, we review the landscape of polypharmacy and examine its impacts through the lens of the ECHO model of Economic, Clinical, and Humanistic Outcomes. We also present strategies for healthcare teams to improve polypharmacy care through comprehensive medication management process that includes medication reconciliation during transitions of care, medication therapy management, and deprescribing. These pharmacist-led interventions have the potential to mitigate adverse outcomes associated with polypharmacy in CKD.

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.

Identifying and reducing inappropriate aspirin use in primary care

OBJECTIVE

Recent studies have called into question the safety of aspirin use for the primary prevention of atherosclerotic cardiovascular disease, particularly in older adults. Therefore, the objectives of this study were to (1) develop a systematic approach to identifying patients aged 70 and older taking aspirin for primary prevention, (2) provide patient and provider education about updated literature and recommendations regarding aspirin safety and (3) evaluate the impact of this intervention on aspirin de-prescribing.

DESIGN

This was a quality improvement intervention with prospective, longitudinal follow-up.

SETTING

This study was conducted in two family medicine practices within an academic medical centre.

PARTICIPANTS

Patients aged 70 years and older with aspirin listed on the current medication list.

METHODS

This is an electronic medical record-based chart review and educational intervention based on shared decision-making to reduce inappropriate aspirin use in primary practice. A chart review process was developed to identify the clinical indication for aspirin use. Patients taking aspirin for primary prevention were flagged for the primary care providers to review. Multilevel logistic regression models assessed factors affecting aspirin de-prescribing and longitudinal trend.

RESULTS

Of 361 patients aged 70 years or older, 145 (40%) were taking aspirin for primary prevention of atherosclerotic cardiovascular disease. After 9 months, aspirin was deprescribed in 42 (29%) of these patients. Patients seen by their providers during the study period had lower odds of having aspirin on their medication list (OR=0.87, 95% CI: 0.81, 0.94) as compared with patients taking aspirin who were not seen by their healthcare provider.

CONCLUSION

This is the first study to develop and implement a method of identifying potentially inappropriate aspirin use based on recent clinical evidence highlighting the risk of aspirin use for primary prevention in older adults. Future initiatives can leverage existing electronic medical record platforms to efficiently identify patients and expand these efforts to larger patient populations.

Prevalence of Potentially Inappropriate Prescriptions According to the New STOPP/START Criteria in Nursing Homes: A Systematic Review

The demand for long-term care is expected to increase due to the rising life expectancy and the increased prevalence of long-term illnesses. Nursing home residents are at an increased risk of suffering adverse drug events due to inadequate prescriptions. The main objective of this systematic review is to collect and analyze the prevalence of potentially inadequate prescriptions based on the new version of STOPP/START criteria in this specific population. Databases (PubMed, Web of Science and Cochrane) were searched for inappropriate prescription use in nursing homes according to the second version of STOPP/START criteria. The risk of bias was assessed with the STROBE checklist. A total of 35 articles were assessed for eligibility. One hundred and forty nursing homes and more than 6900 residents were evaluated through the analysis of 13 studies of the last eight years. The reviewed literature returned prevalence ranges between 67.8% and 87.7% according to the STOPP criteria, according to START criteria prevalence ranged from 39.5% to 99.7%. The main factors associated with the presence of inappropriate prescriptions were age, comorbidities, and polypharmacy. These data highlight that, although the STOPP/START criteria were initially developed for community-dwelling older adults, its use in nursing homes may be a starting point to help detect more efficiently inappropriate prescriptions in institutionalized patients. We hope that this review will help to draw attention to the need for medication monitoring systems in this vulnerable population.

A pharmacist-led medication review service with a deprescribing focus guided by implementation science

Background: Little research addressed deprescribing-focused medication optimization interventions while utilizing implementation science. This study aimed to develop a pharmacist-led medication review service with a deprescribing focus in a care facility serving patients of low income receiving medications for free in Lebanon followed by an assessment of the recommendations' acceptance by prescribing physicians. As a secondary aim, the study evaluates the impact of this intervention on satisfaction compared to satisfaction associated with receiving routine care. Methods: The Consolidated Framework for Implementation Research (CFIR) was used to address implementation barriers and facilitators by mapping its constructs to the intervention implementation determinants at the study site. After filling medications and receiving routine pharmacy service at the facility, patients 65 years or older and taking 5 or more medications, were assigned into two groups. Both groups of patients received the intervention. Patient satisfaction was assessed right after receiving the intervention (intervention group) or just before the intervention (control group). The intervention consisted of an assessment of patient medication profiles before addressing recommendations with attending physicians at the facility. Patient satisfaction with the service was assessed using a validated translated version of the Medication Management Patient Satisfaction Survey (MMPSS). Descriptive statistics provided data on drug-related problems, the nature and the number of recommendations as well as physicians' responses to recommendations. Independent sample t-tests were used to assess the intervention's impact on patient satisfaction. Results: Of 157 patients meeting the inclusion criteria, 143 patients were enrolled: 72 in the control group and 71 in the experimental group. Of 143 patients, 83% presented drug-related problems (DRPs). Further, 66% of the screened DRPs met the STOPP/START criteria (77%, and 23% respectively). The intervention pharmacist provided 221 recommendations to physicians, of which 52% were to discontinue one or more medications. Patients in the intervention group showed significantly higher satisfaction compared to the ones in the control group (p < 0.001, effect size = 1.75). Of those recommendations, 30% were accepted by the physicians. Conclusion: Patients showed significantly higher satisfaction with the intervention they received compared to routine care. Future work should assess how specific CFIR constructs contribute to the outcomes of deprescribing-focused interventions.

Direct-to-consumer strategies to promote deprescribing in primary care: a pilot study

Background

Deprescribing, or the intentional discontinuation or dose-reduction of medications, is an approach to reduce harms associated with inappropriate medication use. We sought to determine how direct-to-patient educational materials impacted patient-provider discussion about and deprescribing of potentially inappropriate medications.

Methods

We conducted a pre-post pilot trial, using an historical control group, at an urban VA medical center. We included patients in one of two cohorts: 1) chronic proton pump inhibitor users (PPI), defined as use of any dose for 90 consecutive days, or 2) patients at hypoglycemia risk, defined by diabetes diagnosis; prescription for insulin or sulfonylurea; hemoglobin A1c < 7%; and age ≥ 65 years, renal insufficiency, or cognitive impairment. The intervention consisted of mailing medication-specific patient-centered EMPOWER (Eliminating Medications Through Patient Ownership of End Results) brochures, adapted to a Veteran patient population, two weeks prior to scheduled primary care appointments. Our primary outcome – deprescribing – was defined as clinical documentation of target medication discontinuation or dose-reduction. Our secondary outcome was documentation of a discussion about the target medication (yes/possible vs. no/absent). Covariates included age, sex, race, specified comorbidities, medications, and utilization. We used chi-square tests to examine the association of receiving brochures with each outcome.

Results

The 348 subjects (253 intervention, 95 historical control) were primarily age ≥ 65 years, white, and male. Compared to control subjects, intervention subjects were more likely to have deprescribing (36 [14.2%] vs. 4 [4.2%], p = 0.009) and discussions about the target medication (31 [12.3%] vs. 1 [1.1%], p = 0.001).

Conclusions

Targeted mailings of EMPOWER brochures temporally linked to a scheduled visit in primary care clinics are a low-cost, low-technology method associated with increases in both deprescribing and documentation of patient-provider medication discussions in a Veteran population. Leveraging the potential for patients to initiate deprescribing discussions within clinical encounters is a promising strategy to reduce drug burden and decrease adverse drug effects and harms.

Applying the AFRAID and FRIGHT clocks to novel preclinical mouse models of polypharmacy

The Frailty Inferred Geriatric Health Timeline (FRIGHT) and Analysis of Frailty and Death (AFRAID) clocks were developed to predict biological age and lifespan, respectively, in mice. Their utility within the context of polypharmacy (≥5 medications), which is very common in older adults, is unknown. In male C57BL/6J(B6) mice administered chronic polypharmacy, monotherapy, and undergoing treatment cessation (deprescribing), we aimed to compare these clocks between treatment groups; investigate whether treatment affected correlation of these clocks with mortality; and explore factors that may explain variation in predictive performance. Treatment (control, polypharmacy, or monotherapy) commenced from age 12 months. At age 21 months, each treatment group was subdivided to continue treatment or have it deprescribed. Frailty index was assessed and informed calculation of the clocks. AFRAID, FRIGHT, frailty index, and mortality age did not differ between continued treatment groups and control. Compared to continued treatment, deprescribing some treatments had inconsistent negative impacts on some clocks and mortality. FRIGHT and frailty index, but not AFRAID, were associated with mortality. The bias and precision of AFRAID as a predictor of mortality varied between treatment groups. Effects of deprescribing some drugs on elements of the clocks, particularly on weight loss, contributed to bias. Overall, in this cohort, FRIGHT and AFRAID measures identified no treatment effects and limited deprescribing effects (unsurprising as very few effects on frailty or mortality), with variable prediction of mortality. These clocks have utility, but context is important. Future work should refine them for intervention studies to reduce bias from specific intervention effects.

Attitudes toward deprescribing for hospital inpatients

Clinicians are responsible for both commencing and stopping medications. This study evaluates the attitudes of older acute medical inpatients about deprescribing. Overall, patients are positive toward stopping medications, want to be involved and do not feel a clinician is giving up on them if a medication is stopped. Patients on fewer medications counterintuitively feel a greater medication burden, are more interested in being involved in decision making and consider deprescribing appropriate to a greater degree than patients who are taking more medications. Conversely, they also reported greater concerns about stopping medications. We discuss these findings in the context of the positive and negative effects of deprescribing, in the context of patient engagement and shared decision making, and how clinicians can work with inpatients to reduce potentially inappropriate medications.

Use of a Deprescribing Tool in an Interdisciplinary Primary-Care Patient-Aligned Care Team

Objective: To pilot the VIONE approach in a single Primary Care Patient Aligned Care Team (PACT). The authors aim for the Clinical Pharmacy Specialist (CPS) to perform 20 comprehensive medication reviews (CMRs) and the pilot PACT physician (PCP) to complete 200 VIONE discontinuations. Cost avoidance and CPS recommendations will also be analyzed. Polypharmacy is associated with increased risk of adverse drug events, falls, hospitalizations, and death. VIONE is a deprescribing tool that assists providers in identifying inappropriate medications. Design: Quality Improvement Setting: Single VA Health Care System (VAHCS) Participants: High-risk veterans in pilot PACT Interventions: The CPS educated the PCP regarding VIONE methodology and assisted with CMRs. When deprescribing was warranted, VIONE discontinuation reasons were selected in the Computerized Patient Record System (CPRS). Data were electronically stored in a national dashboard. Results: The authors identified 231 veterans at risk for polypharmacy-related adverse events. The PCP and CPS were able to reach 99 veterans and make 136 medication discontinuations between September 1, 2019, and March 1, 2020. The CPS performed 20 CMRs, resulting in 90 deprescribing recommendations. Thirty-eight CPS recommendations were accepted and contributed $18,835.95 to the sum annualized cost avoidance of $21,904.80. Conclusion: The VIONE methodology was successfully implemented in the pilot PACT. The utilization of the CPS was associated with an increased average number of medication discontinuations per veteran and contributed to cost avoidance.

Potentially Inappropriate Medications Use among Older Adults with Comorbid Diabetes and Hypertension in an Ambulatory Care Setting

OBJECTIVE

This study aims to estimate the prevalence of PIMs use and its associated factors among older adults with comorbid diabetes and hypertension.

METHODS

A cross-sectional retrospective study was used, including 1,853 older adults (age ≥65 years) with diabetes and hypertension who visited an ambulatory care setting. The study objectives were to estimate the prevalence and factors associated with PIMs use based on the 2019 American Geriatric Society (AGS) Beers criteria.

RESULTS

Almost one out of two individuals had PIMs used, with the average number of medications taken being seven. The most commonly prescribed PIMs were the use of gastrointestinal and endocrine medications. High risk of PIMs use was among those with ischemic heart disease, anxiety, and polypharmacy.

CONCLUSIONS

Given the higher PIMs use among older adults with diabetes and hypertension comorbidities, tailored strategies and interventions to minimize PIMs use in this population are warranted.

Deprescribing to reduce polypharmacy: study protocol for a randomised controlled trial assessing deprescribing of anticholinergic and sedative drugs in a cohort of frail older people living in the community

BACKGROUND

Targeted deprescribing of anticholinergic and sedative medications in older people may improve their health outcomes. This trial will determine if pharmacist-led reviews lead to general practitioners deprescribing anticholinergic and sedative medications in older people living in the community.

METHODS AND ANALYSIS

The standard protocol items: Recommendations for Interventional Trials (SPIRIT) checklist was used to develop and report the protocol. The trial will involve older adults stratified by frailty (low, medium, and high). This will be a pragmatic two-arm randomized controlled trial to test general practitioner uptake of pharmacist recommendations to deprescribe anticholinergic and sedative medications that are causing adverse side effects in patients.

STUDY POPULATION

Community-dwelling frail adults, 65 years or older, living in the Canterbury region of New Zealand, seeking publicly funded home support services or admission to aged residential care and taking at least one anticholinergic or sedative medication regularly.

INTERVENTION

New Zealand registered pharmacists using peer-reviewed deprescribing guidelines will visit participants at home in the community, review their medications, and recommend anticholinergic and sedative medications that could be deprescribed to the participant's general practitioner. The total use of anticholinergic and sedative medications will be quantified using the Drug Burden Index (DBI).

OUTCOMES

The primary outcome will be the change in total DBI between baseline and 6-month follow-up. Secondary outcomes will include entry into aged residential care, prolonged hospitalization, and death.

DATA COLLECTION POINTS

Data will be collected at the time of interRAI assessments (T0), at the time of the baseline review (T1), at 6 months following the baseline review (T2), and at the end of the study period, or end of study participation for participants admitted into aged residential care, or who died (T3).

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Human, Disability and Ethics Committee: ethical number (17CEN265).

Ethical Tenets of PRN Medicines Management in Healthcare Settings: A Clinical Perspective

Prescription and administration of pro re nata (PRN) medications has remained a poorly discussed area of the international literature regarding ethical tenets influencing this type of medication practice. In this commentary, ethical tenets of PRN medicines management from the clinical perspective based on available international literature and published research have been discussed. Three categories were developed by the authors for summarising review findings as follows: 'benefiting the patient', 'making well-informed decision', and 'follow up assessment' as pre-intervention, through-intervention, and post-intervention aspects, respectively. PRN medicines management is mainly intertwined with the ethical tenets of beneficence, nonmaleficence, dignity, autonomy, justice, informed consent, and error disclosure. It is a dynamic process and needs close collaboration between healthcare professionals especially nurses and patients to prevent unethical practice.

Physicians' perceived barriers and enablers for deprescribing among older patients at public primary care clinics: a qualitative study

Background Increased harmful effects of medication resulting from polypharmacy, especially among older patients, is a significant concern globally. Hence, continuous medication review and withdrawal of inappropriate medications are essential to improve patient safety. Objective To explore physicians' perceived barriers and enablers of deprescribing among older patients in the public primary healthcare setting. Setting Public primary care clinics in the northern states of Malaysia. Methods A semi-structured, face-to-face interview was conducted among physicians working in eight primary care clinics in northern Malaysia using a purposive sampling approach. Interviews were conducted using validated topic guides. All the responses were recorded, transcribed verbatim, validated, and analysed for the emerging themes using thematic analysis. Main outcome measure Physicians perceived barriers and enablers of deprescribing among geriatric patients. Results A total of eleven physicians were interviewed. Seven emerging themes were identified, which are categorised under barriers and enablers of deprescribing. The barriers were patient-specific, prescriber-specific, and healthcare provision and system. Prescriber deprescribing competencies, medication-specific outcomes, availability of empirical evidence, and pharmacist's role were the enablers identified. Conclusion Patient-specific barriers were identified as a significant challenge for deprescribing. Improving competencies on deprescribing was the repeatedly adduced enabler by physicians. The development of targeted educational training can help to reduce the obstacles faced by prescribers.

Attitudes and beliefs of patients and primary caregivers towards deprescribing in a tertiary health care facility

Background

Good prescribing practices form the essence of drug therapy for better patient care. The major aim of better prescribing is to improve rational prescribing. Deprescribing gained momentum in recent decades.

Objective

This study aimed to explore the attitude and beliefs of deprescribing among patients and their caregivers forming dyads in a tertiary health care facility.

Methods

Cross-sectional, questionnaire-based prospective study done for two months. Attitude towards deprescribing was assessed by using validated rPATD (revised Patient attitude towards deprescribing) questionnaire. Cohen's kappa coefficient was used to measure the agreement between the views of people and their caregivers forming dyads about medication cessation.

Results

312 patients and caregivers (156 forming dyads) participated in the study. Among 156 patients, 25.6% were hypertensives & 21.2% had diabetes. 41.7% were between 36-50 years of age. Only 16.7% belong to the elderly age group. 2.5% were taking >5 medications. 43.6% of patients and 62.2% of caregivers were female. 51.3% of the patients were willing to stop one or more of their regular medicine(s) under the treating physician's advice, but 62% were satisfied with their current medicine(s). 33.4% were reluctant to stop taking medicines for a long time.

Conclusions

In our study, more than 50% of people and their caregivers were willing to try medication cessation under their physician's recommendation. There was moderate agreement between patients and their caregivers in the trial of medication cessation. Thus, the results obtained from this study may help towards improving rationalized prescribing practices in the institutional setup.

Mortality associated with stopping statins in the oldest-old - with and without ischemic heart disease

The association between stopping statins and 1-year mortality in the general population of the oldest-old - with or without ischemic heart disease (IHD) - has been studied herein for the first time.This was a retrospective study. Included were all consecutive patients (n = 369) aged 80 years or more (mean age 87.8 years) hospitalized in a single Geriatrics department during 1 year. The study group included 140 patients in whom statins were stopped upon admission (statin stoppers). The control group included 229 patients who did not use statins in the first place (statin non-users). All-cause 1-year mortality rates were studied in both groups following propensity score matching and in IHD patients separately.Overall, 110 (29.8%) patients died during the year following admission: 38 (27.1%) statin stoppers and 72 (31.4%) statin non-users (P = .498). Cox regression analysis showed no association between stopping statins and 1-year mortality in the crude analysis (hazard ratio [HR] 0.976, 95% confidence interval [CI] 0.651-1.463, P = .907) and following propensity score matching (HR 1.067, 95%CI 0.674-1.689, P = .782). Among 108 IHD patients, 38 (35.2%) patients died during the year following admission: 18 (27.7%) statin stoppers and 20 (46.5%) statin non-users (P = .059). Cox regression analysis showed a nearly significant association between stopping statins (rather than not using statins) in IHD patients and lower 1-year mortality (HR 0.524, 95%CI 0.259-1.060, P = .072).Hence, stopping statins in the general population of the oldest-old - with or without IHD - is possibly safe. Future studies including the oldest-old statin continuers are warranted to confirm this observation.

Deprescribing in the Older Patient: A Narrative Review of Challenges and Solutions

Polypharmacy is a major challenge in healthcare for older people, and is associated with increased risks of adverse outcomes, such as delirium, falls, frailty, cognitive impairment and hospitalization. There is significant public and professional interest in the role of deprescribing in reducing medication-related harms in older people. We aim to provide a narrative review of 1) the safety and efficacy of deprescribing interventions, 2) the challenges and solutions of deprescribing research and implementation in clinical practice, and 3) the benefits of using Computerized Clinical Decision Support Systems (CCDSS) and Quality Indicators (QIs) in deprescribing research and practice. Deprescribing is an established management strategy to minimize polypharmacy and potentially inappropriate medications. There is limited clinical evidence for its efficacy on global and geriatric outcomes. Various challenges at patient, healthcare professional and healthcare system levels may impact on the success of deprescribing interventions in research and practice. Management strategies that target all levels of the healthcare system are required to overcome these challenges. Future studies may consider large multicenter prospective designs to establish the effects and sustainability of deprescribing interventions on clinical outcomes.

A narrative review of updates in deprescribing research

BACKGROUND/OBJECTIVES

Deprescribing is a strategy intended to reduce harms associated with potentially inappropriate medications. Reflective of the growing interest in deprescribing, there has been an increase in related research to better understand the landscape, opportunities for improvement, how best to develop and implement interventions, and remaining knowledge gaps that can be addressed with additional study.

DESIGN

We conducted a narrative review of recent deprescribing literature.

SETTING

As part of the US Deprescribing Network's inaugural conference in October 2020, we presented a narrative review of recent deprescribing literature to an audience with a range of clinical and research expertise.

PARTICIPANTS

We searched four databases for English-language articles published between January 1, 2019 and August 31, 2020.

MEASUREMENTS

We evaluated titles, abstracts, and full-length manuscripts for relevance, novelty, rigor and variety of methods; we also aimed for broad representation of authors, institutions, and nations.

RESULTS

The initial search returned 199 citations, from which we reviewed 18 full-length manuscripts, selecting 10 articles to present. Salient themes included missed opportunities to deprescribe in potentially eligible patients, with variable impact of medication- and patient-level factors, along with differing perspectives and behaviors between geriatricians, internists, and cardiologists. Clinical, financial, and economic drivers were also evaluated. Finally, attention was given to issues applicable to deprescribing research, including difficulty recruiting trial participants, perspectives of investigators, and integration of findings into clinical practice.

CONCLUSION

This narrative review summarizes key advances in the field while also identifying priority areas for additional research.

General practitioners' deprescribing decisions in older adults with polypharmacy: a case vignette study in 31 countries

BACKGROUND

General practitioners (GPs) should regularly review patients' medications and, if necessary, deprescribe, as inappropriate polypharmacy may harm patients' health. However, deprescribing can be challenging for physicians. This study investigates GPs' deprescribing decisions in 31 countries.

METHODS

In this case vignette study, GPs were invited to participate in an online survey containing three clinical cases of oldest-old multimorbid patients with potentially inappropriate polypharmacy. Patients differed in terms of dependency in activities of daily living (ADL) and were presented with and without history of cardiovascular disease (CVD). For each case, we asked GPs if they would deprescribe in their usual practice. We calculated proportions of GPs who reported they would deprescribe and performed a multilevel logistic regression to examine the association between history of CVD and level of dependency on GPs' deprescribing decisions.

RESULTS

Of 3,175 invited GPs, 54% responded (N = 1,706). The mean age was 50 years and 60% of respondents were female. Despite differences across GP characteristics, such as age (with older GPs being more likely to take deprescribing decisions), and across countries, overall more than 80% of GPs reported they would deprescribe the dosage of at least one medication in oldest-old patients (> 80 years) with polypharmacy irrespective of history of CVD. The odds of deprescribing was higher in patients with a higher level of dependency in ADL (OR =1.5, 95%CI 1.25 to 1.80) and absence of CVD (OR =3.04, 95%CI 2.58 to 3.57).

INTERPRETATION

The majority of GPs in this study were willing to deprescribe one or more medications in oldest-old multimorbid patients with polypharmacy. Willingness was higher in patients with increased dependency in ADL and lower in patients with CVD.

Potentially inappropriate medication and attitudes of older adults towards deprescribing

INTRODUCTION

Multimorbidity and polypharmacy are current challenges when caring for the older population. Both have led to an increase of potentially inappropriate medication (PIM), illustrating the need to assess patients' attitudes towards deprescribing. We aimed to assess the prevalence of PIM use and whether this was associated with patient factors and willingness to deprescribe.

METHOD

We analysed data from the LESS Study, a cross-sectional study on self-reported medication and on barriers and enablers towards the willingness to deprescribe (rPATD questionnaire). The survey was conducted among multimorbid (≥3 chronic conditions) participants ≥70 years with polypharmacy (≥5 long-term medications). A subset of the Beers 2019 criteria was applied for the assessment of medication appropriateness.

RESULTS

Data from 300 patients were analysed. The mean age was 79.1 years (SD 5.7). 53% had at least one PIM (men: 47.8%%, women: 60.4%%; p = 0.007). A higher number of medications was associated with PIM use (p = 0.002). We found high willingness to deprescribe in both participants with and without PIM. Willingness to deprescribe was not associated with PIM use (p = 0.25), nor number of PIMs (p = 0.81).

CONCLUSION

The willingness of older adults with polypharmacy towards deprescribing was not associated with PIM use in this study. These results suggest that patients may not be aware if they are taking PIMs. This implies the need for raising patients' awareness about PIMs through education, especially in females, in order to implement deprescribing in daily practice.

Withdrawal of antihypertensive drugs in older people

BACKGROUND

Hypertension is an important risk factor for subsequent cardiovascular events, including ischaemic and haemorrhagic stroke, myocardial infarction, heart failure, chronic kidney disease, cognitive decline and premature death. Overall, the use of antihypertensive medications has led to reduction in cardiovascular disease, morbidity rates and mortality rates. However, the use of antihypertensive medications is also associated with harms, especially in older people, including the development of adverse drug reactions, drug-drug interactions and can contribute to increasing medication-related burden. As such, discontinuation of antihypertensives may be considered and appropriate in some older people.

OBJECTIVES

To investigate whether withdrawal of antihypertensive medications is feasible, and evaluate the effects of withdrawal of antihypertensive medications on mortality, cardiovascular outcomes, hypertension and quality of life in older people.

SEARCH METHODS

The Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials up to April 2019: the Cochrane Hypertension Specialised Register, CENTRAL (2019, Issue 3), Ovid MEDLINE, Ovid Embase, the WHO International Clinical Trials Registry Platform, and ClinicalTrials.gov. We also conducted reference checking, citation searches and, when appropriate, contacted study authors to identify any additional studies. The searches had no language restrictions.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) of withdrawal versus continuation of antihypertensive medications used for hypertension or primary prevention of cardiovascular disease in older adults (defined as 50 years and over). Participants were eligible if they lived in the community, residential aged care facilities, or were based in hospital settings. We sought to include trials looking at the complete withdrawal of the antihypertensive medication, and those focusing on a dose reduction of the antihypertensive medicine.

DATA COLLECTION AND ANALYSIS

We compared the intervention of discontinuing or reducing antihypertensive medication to usual treatment using mean differences (MD) and 95% confidence intervals (95% CIs) for continuous variables and we used Peto odds ratios (ORs) and 95% CI for binary variables. Our primary outcomes included: mortality, myocardial infarction, development of adverse drug reactions or adverse drug withdrawal reactions. Secondary outcomes included: blood pressure, hospitalisation, stroke, success of withdrawing from antihypertensives, quality of life, and falls. Two authors independently, and in duplicate, conducted all stages of study selection, data extraction and quality assessment.

MAIN RESULTS

Six RCTs met the inclusion criteria and were included in the review (1073 participants). Study duration and follow-up ranged from 4 weeks to 56 weeks. Meta-analysis of studies showed that, in the discontinuation group compared to continuation, the odds for all-cause mortality were 2.08 (95% CI 0.79 to 5.46; low certainty of evidence), for myocardial infarction 1.86 (95% CI 0.19 to 17.98; very low certainty of evidence) and for stroke 1.44 (95% CI 0.25 to 8.35; low certainty of evidence). Blood pressure was higher in the discontinuation group than the continuation group (systolic blood pressure: MD = 9.75 mmHg, 95% CI 7.33 to 12.18; and diastolic blood pressure: MD = 3.5 mmHg, 95% CI 1.82 to 5.18; low certainty of evidence). For the development of adverse events, meta-analysis was not possible; antihypertensive discontinuation did not appear to increase the risk of adverse events and may lead to resolution of adverse drug reactions, although eligible studies had limited reporting of adverse effects of drug withdrawal (very low certainty of evidence). One study reported hospitalisation with an odds ratio of 0.83 for discontinuation compared to continuation (95% CI 0.33 to 2.10; low certainty of evidence). No studies were identified which reported falls. Between 10.5% and 33.3% of participants in the discontinuation group compared to 9% to 15% in the continuation group experienced raised blood pressure or other clinical criteria (as pre-defined by the studies) that would require restarting of therapy/removal from the study. The sources of bias included selective reporting (reporting bias), lack of blinding of outcome assessment (detection bias), incomplete outcome data (attrition bias), and lack of blinding of participants and personnel (performance bias).

AUTHORS' CONCLUSIONS

There is no evidence of an effect of discontinuing compared with continuing antihypertensives used for hypertension or primary prevention of cardiovascular disease in older adults on all-cause mortality and myocardial infarction. The evidence was low to very low certainty mainly due to small studies and low event rates. These limitations mean that we cannot make any firm conclusions about the effect of deprescribing antihypertensives on these outcomes. Future research should focus on populations with the greatest uncertainty of the benefit:risk ratio for use of antihypertensive medications, such as those with frailty, older age groups and those taking polypharmacy, and measure clinically important outcomes such as falls, quality of life and adverse drug events.

Factors affecting medication adherence among pre-dialysis chronic kidney disease patients: a systematic review and meta-analysis of literature

BACKGROUND

Medication adherence plays an essential role in slowing the progression of chronic kidney disease (CKD). This review aims to summarise factors affecting medication adherence among these pre-dialysis CKD patients.

METHODS

A systematic review of the literature was performed in Medline®, Embase®, SCOPUS® and CINAHL®. Peer-reviewed, English language articles which evaluated factors associated with medication adherence among pre-dialysis CKD patients were included. Meta-analysis was performed to assess the pooled medication adherence rates across studies. Factors identified were categorised using the World Health Organization's five dimensions of medication adherence (condition, patient, therapy, health-system, and socio-economic domains).

RESULTS

Of the 3727 articles reviewed, 18 articles were included. The pooled adherence rate across studies was 67.4% (95% CI 61.4-73.3%). The most studied medication class was anti-hypertensives (55.6%). A total of 19 factors and 95 sub-factors related to medication adherence were identified. Among condition-related factors, advanced CKD was associated with poorer medication adherence. Patient-related factors that were associated with lower medication adherence included misconceptions about medication and lack of perceived self-efficacy in medication use. Therapy-related factors which were associated with poorer medication adherence included polypharmacy while health system-based factors included loss of confidence in the physician. Socioeconomic factors such as poor social support and lower education levels were associated with poorer medication adherence.

CONCLUSION

Factors associated with poor medication adherence among pre-dialysis CKD patients were highlighted in this review. This will aid clinicians in designing interventions to optimise medication adherence among pre-dialysis CKD patients.

Confronting Medicine's Dichotomies: Older Adults' Use of Interpretative Repertoires in Negotiating the Paradoxes of Polypharmacy and Deprescribing

To address the risks associated with polypharmacy, health care providers are investigating the feasibility of deprescribing programs as part of routine medical care to reduce medication burden to older adults. As older adults are enrolled in these programs, they are confronted with two dominant and legitimate accounts of medications, labeled the medication paradox: medications keep you healthy but they might be making you sick. We investigated how the medication paradox operates in the lives of older adults. In-depth qualitative interviews were conducted and analyzed with older adults aged 70+ to identify the various paradoxes that seniors live through regarding their medications and the narratives that they engage to negotiate these contradictions. Older adults were found to have established interpretative repertoires to make sense of the incongruent narratives of the medication paradox. In this article, we demonstrate older adults' efforts to carve out their unique place in the dichotomized institution of medicine.

Reduction of the long-term use of proton pump inhibitors by a patient-oriented electronic decision support tool (arriba-PPI): study protocol for a randomized controlled trial

BACKGROUND

Proton pump inhibitors (PPIs) are increasingly being prescribed, although long-term use is associated with multiple side effects. Therefore, an electronic decision support tool with the aim of reducing the long-term use of PPIs in a shared decision-making process between general practitioners (GPs) and their patients has been developed. The developed tool is a module that can be added to the so-called arriba decision support tool, which is already used by GPs in Germany in routine care. In this large-scale cluster-randomized controlled trial we evaluate the effectiveness of this arriba-PPI tool.

METHODS

The arriba-PPI tool is an electronic decision support system that supports shared decision-making and evidence-based decisions around the long-term use of PPIs at the point of care. The tool will be evaluated in a cluster-randomized controlled trial involving 210 GP practices and 3150 patients in Germany. GP practices will be asked to recruit 20 patients aged ≥ 18 years regularly taking PPIs for ≥ 6 months. After completion of patient recruitment, each GP practice with enrolled patients will be cluster-randomized. Intervention GP practices will get access to the software arriba-PPI, whereas control GPs will treat their patients as usual. After an observation period of six months, GP practices will be compared regarding the reduction of cumulated defined daily doses of PPI prescriptions per patient.

DISCUSSION

Our principal hypothesis is that the application of the arriba-PPI tool can reduce PPI prescribing in primary care by at least 15% compared to conventional strategies used by GPs. A positive result implies the implementation of the arriba-PPI tool in routine care.

Patient Education and Pharmacist Consultation Influence on Nonbenzodiazepine Sedative Medication Deprescribing Success for Older Adults

INTRODUCTION

Use of nonbenzodiazepine sedative hypnotics or "Z-drugs"-including eszopiclone, zolpidem, or zaleplon-is discouraged for older adults; however, these medications commonly are prescribed to treat insomnia in this population. We evaluated the impact of direct-to-patient education, with or without a pharmacist consultation, on Z-drug discontinuation among Kaiser Permanente Northwest members age 64 years and older.

METHODS

We randomized 150 patients to usual care (UC), educational information only, or educational information and pharmacist consultation. Patients age 64 years and older who received 2 to 3 Z-drug fills in 2016 were included. Logistic regression was used to calculate odds of discontinuation at 6 months among patients who received either intervention, compared with those who received UC.

RESULTS

Patients who received education only and education plus pharmacist consultation were significantly more likely to discontinue Z-drug use than those who received UC (28/50 of those who received education only and 27/49 of those who received education plus consultation vs 13/50 patients who received UC). After controlling for patient demographics, comorbidity, and antianxiety and antidepressant medication use, patients who received education only had greater odds of Z-drug discontinuation than those in the UC group (adjusted odds ratio = 4.02, 95% confidence interval = 1.66-9.77). Patients who received education and a pharmacist call also had greater odds of discontinuing use of these drugs than those in the UC group (adjusted odds ratio = 4.10, 95% confidence interval = 1.65-10.19).

CONCLUSION

Patients who received direct-to-patient education with or without a pharmacist consultation were significantly more likely to discontinue Z-drug use than patients receiving UC. Providing evidence-based information about Z-drug use is an effective and low-resource method to encourage drug discontinuation.

Reducing Potentially Inappropriate Medications in Older Adults: A Way Forward

La réduction des médicaments potentiellement inappropriés (MPI) chez les personnes âgées est un enjeu important selon de nombreux cliniciens et chercheurs à travers le monde, car ces médicaments accroissent significativement la morbidité et la mortalité dans la population plus âgée. La prévalence des MPI est un problème répandu malgré l’existence de plusieurs critères explicites et implicites de réduction des MPI chez les personnes âgées, les plus courants étant les critères de Beers, les critères STOPP/START et plusieurs critères nationaux spécifiques. Cette revue non systématique visait à examiner les critères de référence pour la réduction des MPI et à clarifier le rôle de certaines mesures, dont la déprescription, pour optimiser la prescription des médicaments chez les personnes âgées. Des recherches par mots-clés et termes MeSH ont été menées dans des bases de données électroniques. Les nombreux critères disponibles ont chacun leurs avantages et inconvénients. La déprescription, qui vise à réduire l’utilisation des MPI, a considérablement gagné en importance dans les initiatives associées à l’amélioration des pratiques de prescription. La déprescription est une approche méthodique qui implique l’arrêt graduel, éclairé et individualisé des médicaments inappropriés, avec un suivi rigoureux des patients pour assurer la détection d’événements indésirables ou de symptômes de rebond. Une approche combinée centrée sur le patient et le soignant favorise la collaboration entre les prescripteurs et les pharmaciens afin de réduire le nombre de MPI chez les personnes âgées.

The impact of in hospital patient-education intervention on older people's attitudes and intention to have their benzodiazepines deprescribed: a feasibility study

Background

Long-term benzodiazepine use in the older population is common and is associated with significant harm. The provision of a patient-educational booklet during hospitalization may encourage patients to discuss review and possible deprescribing of benzodiazepine therapy with their health professionals. The aim of this study was to assess the feasibility and effect of a patient empowerment intervention in hospital inpatients on patient initiation of a discussion about deprescribing benzodiazepines versus usual care.

Methods

A feasibility interventional study using a patient-empowerment education intervention was conducted at a Sydney teaching hospital. Patients aged ⩾ 65 years, prescribed a benzodiazepine, and able to provide consent were invited to participate in the study. Participants were randomly allocated to intervention or control group (1:1). Intervention participants received the patient-empowerment booklet and control received usual care. All participants received 1-month follow-up phone interviews to assess medication and attitudinal changes.

Results

A total of 42 participants were recruited (20 intervention and 22 control). The average age was 71.5 (interquartile range: 69.0-80.3) and 54.8% were females. There was no difference in baseline characteristics between intervention and control groups (p > 0.05). At baseline, 65.0% of participants (53.0% intervention, 86.0% control) were not concerned about the potential benzodiazepine side effects. Twenty-nine participants (15 intervention and 14 control) completed 1-month follow up; 22 participants (11 intervention and 11 control) were discharged on the benzodiazepine. Among these, 13 (59.1%) had ceased benzodiazepine at 1-month follow up [46.2% (n = 6) intervention; 53.8% (n = 7) control]. In the intervention group, 33.3% (n = 5) of participants had initiated a discussion with their doctor or pharmacist about stopping the benzodiazepine compared with 35.7% (n = 5) in the control group.

Conclusion

Cessation of benzodiazepines 1 month following discharge was common. Future larger studies are required to confirm the effectiveness of providing a patient-empowerment booklet on reducing benzodiazepine use and other potentially inappropriate medications.

Impact of deprescribing rounds on discharge prescriptions: an interventional trial

Background Successful deprescribing practices are required to address issues associated with polypharmacy but are hindered by minimal interprofessional collaboration, time constraints, concern for negative outcomes, and absence of a systematic and evidence-based approach. Objective Determine the impact of pharmacist-led deprescribing rounds within a clinical teaching unit (CTU) the number of home medications discontinued upon hospital discharge. Setting Canadian tertiary care hospital. Methods Prospective, dual-arm, interventional study conducted in a single centre, from November 23rd, 2015 to August 30th, 2016. All patients ≥ 19 years old admitted under the CTU were considered for enrolment if on medication(s) prior to admission and patients were excluded if not taking any medications. Study arm allocation alternated daily between the two teams. The control arm operated as per standard whereas the intervention arm's pharmacist used a deprescribing guide and medication review to identify medications eligible for discontinuation prior to discussing during daily rounds. Discharge documents communicated medication changes to patient and primary healthcare providers. The study was sufficiently powered. Main outcome measure The difference of number of home medications discontinued at discharge between the intervention and control groups. Results 171 and 187 patients were allocated to the intervention and control arms, respectively. No significant differences of baseline characteristics existed between groups. Main outcome measure results showed that deprescribing rounds resulted in significantly more medications deprescribed compared to control (65% vs. 38%; p = 0.001). The rates of readmission and emergency department visits were reduced in the intervention arm. Conclusions Incorporating deprescribing rounds into routine care led to significantly greater discontinuation of medications without increasing rate of emergency department visits or hospital admissions.Trial registration ISRCTN11751440.

Deprescribing in primary care in Portugal (DePil17-20): a three-phase observational and experimental study protocol

INTRODUCTION

Polypharmacy is commonly defined as the simultaneous taking of five or more drugs. Deprescribing is the process of tapering or stopping medications with the aim of improving patient outcomes and optimising current therapy, and there are several tools aiming at identifying potentially inappropriate medications, especially in the elderly. The direct involvement of patients and their caregivers in the choice and administration of drugs has long been known to be very important, but it is not usually applied. The aim of this study is to assess the knowledge of older adults about deprescription, the effect on willingness to have regular medications deprescribed and its quality-of-life outcome.

METHODS AND ANALYSIS

This study protocol comprises three phases. The first two phases will be nationwide and aim to evaluate the prevalence and patterns of polypharmacy and assess the barriers and facilitators of deprescribing perceived by older adults, as well as their willingness to have regular medications deprescribed and to self-medicate. The third and last phase will be a non-pharmacological randomised clinical study to measure older patients' acceptance to have regular medications deprescribed and related quality of life.

ETHICS AND DISSEMINATION

The study will be conducted in accordance with the principles expressed in the Declaration of Helsinki. It has been approved by the Ethics Committee of the University of Beira Interior and Portuguese National Data Protection Commission. Study results will be published in peer-reviewed journals and presented at national and international conferences. In short, no action will be taken without written consent from patients and doctors.

Is Excessive Polypharmacy a Transient or Persistent Phenomenon? A Nationwide Cohort Study in Taiwan

Objectives: Target populations with persistent polypharmacy should be identified prior to implementing strategies against inappropriate medication use, yet limited information regarding such populations is available. The main objectives were to explore the trends of excessive polypharmacy, whether transient or persistent, at the individual level. The secondary objectives were to identify the factors associated with persistently excessive polypharmacy and to estimate the probabilities for repeatedly excessive polypharmacy.

Methods: Retrospective cohort analyses of excessive polypharmacy, defined as prescription of ≥ 10 medicines at an ambulatory visit, from 2001 to 2013 were conducted using a nationally representative claims database in Taiwan. Survival analyses with log-rank test of adult patients with first-time excessive polypharmacy were conducted to predict the probabilities, stratified by age and sex, of having repeatedly excessive polypharmacy.

Results: During the study period, excessive polypharmacy occurred in 5.4% of patients for the first time. Among them, 63.9% had repeatedly excessive polypharmacy and the probabilities were higher in men and old people. Men versus women, and old versus middle-aged and young people had shorter median excessive polypharmacy-free times (9.4 vs. 5.5 months, 5.3 vs. 10.1 and 35.0 months, both p < 0.001). Overall, the probabilities of having no repeatedly excessive polypharmacy within 3 months, 6 months, and 1 year were 59.9, 53.6, and 48.1%, respectively.

Conclusion: Although male and old patients were more likely to have persistently excessive polypharmacy, most cases of excessive polypharmacy were transient or did not re-appear in the short run. Systemic deprescribing measures should be tailored to at-risk groups.

Patient attitudes and experiences that predict medication discontinuation in the Veterans Health Administration

OBJECTIVES

Polypharmacy is associated with adverse medication effects. One potential solution is deprescribing, which is the intentional, proactive, rational discontinuation of a medication that is no longer indicated or for which the potential harms outweigh the potential benefits. We identified patient characteristics, attitudes, and health care experiences associated with medication discontinuation.

DESIGN, SETTING, AND PARTICIPANTS

We conducted a national mail survey, with the use of the Patient Perceptions of Discontinuation (PPoD) instrument, of 1600 veterans receiving primary care at Veterans Affairs (VA) medical centers and prescribed 5 or more concurrent medications.

MAIN OUTCOME MEASURES

The primary outcome was the response to: "Have you ever stopped taking a medicine (with or without your doctor's knowledge)?" The primary predictors of interest were 8 validated attitudinal scales. Other predictors included demographics, health status, and health care experiences.

RESULTS

Respondents (n = 803; adjusted response rate 52%) were predominantly male (85%); non-Hispanic white (68%), 65 years of age or older (60%), and with poor (16%) or fair (45%) health. Participant attitudes toward medications and their providers were generally favorable. One in 3 patients (34%) reported having stopped a medicine in the past. In a multivariable logistic regression model (P < 0.001; pseudo-R2 = 0.31; c-statistic = 0.82), factors associated with discontinuation included being told or asking to stop a medicine, greater interest in deprescribing and shared decision making, and higher education. Factors associated with decreased discontinuation were more prescriptions, higher trust in provider, and seeing a VA clinical pharmacist.

CONCLUSION

More highly educated patients with interest in deprescribing and shared decision making may be more receptive to discontinuation discussions. Future research evaluating how to incorporate this survey and these findings into clinical workflow through the design of clinical interventions may help to promote safe and rational medication use.

A narrative review of the safety concerns of deprescribing in older adults and strategies to mitigate potential harms

INTRODUCTION

As with prescribing or continuing medications, deprescribing brings with it the potential for harm as well as benefit. Uncertainty and avoidance of harm has been reported as a barrier to deprescribing in practice and may contribute to continuation of inappropriate medications.

AREAS COVERED

This narrative review covers four main safety concerns/potential harms of deprescribing in older adults: adverse drug withdrawal events, return of medical condition(s), reversal of drug-drug interactions and damage to the doctor-patient relationship. These are discussed in relation to medications in general, with some examples of medication classes used to illustrate the potential safety concerns. The majority of these harms can be minimized or even prevented by using a patient-centered, structured deprescribing process with planning, tapering and close monitoring during, and after medication withdrawal.

EXPERT OPINION

More research is needed into the safety concerns of deprescribing, however, avenues exist during drug development and post-marketing surveillance to gain knowledge on this topic. Questions remain about when it is suitable to discontinue certain medications/medication classes and there is uncertainty about the harms and benefits of both medication continuation and discontinuation in complex older adults.

Multimorbidity and Polypharmacy in Family Medicine Residency Practices

Background: Prescription-related problems among older adults have been of great interest. However, few data are available regarding the prevalence of these problems in US family medicine residency practices (FMRPs). Objective: The aim of this research was to examine the prevalence of multimorbidity, polypharmacy, and potentially inappropriate medications (PIMs) use among older adults who visited 5 FMRPs more than once a year. Methods: A cross-sectional hospital record review for patients 65 years or older who visited 1 of the 5 university-affiliated FMRPs at least twice during January 1 to December 31, 2014, was conducted. The prevalence of multimorbidity (24 chronic index conditions), polypharmacy, and PIMs use was examined. Results: A total of 1084 patients were included in the analyses. The most common chronic conditions were hypertension (87.8%), hyperlipidemia (69.7%), and osteoarthritis (56.1%). The mean number of chronic conditions was 5.3 (SD 2.6). The prevalence of multimorbidity (≥2 chronic conditions) was 95.6%. Among these multimorbid older adults (N = 1036), the mean number of medication orders was 9.04 (SD 4.36) and 1.57 (SD 0.92) for PIMs, 86.1% met polypharmacy standards (≥5 medications), and 33.4% were prescribed one or more PIMs. The proportion of patients with fewer prescriptions at the last visit was 45.4% in the polypharmacy group and 38.0% in the PIMs group. Conclusion: Our results suggest a high level of morbidity and complexity among older adults receiving care in FMRPs. Improving the continuity of care as well as promoting interdisciplinary collaboration would have potential to reduce these prescription-related problems. Further research and education to address polypharmacy and PIMs among this population at FMRPs are required.

Pharmacist-initiated deprescribing in hospitalised elderly: prevalence and acceptance by physicians

Objectives

Deprescribing can help reduce polypharmacy in the elderly and hospitalisation presents an opportunity to re-evaluate the use of medications. The aim of this study was to describe the drugs that were commonly suggested by pharmacists to be deprescribed in hospitalised elderly, and the factors associated with acceptance by physicians.

Methods

A retrospective, cross-sectional study was conducted in a tertiary hospital in Singapore. All pharmacist interventions on deprescribing in inpatient elderly aged ≥65 years, made between July and December 2015 were included. Comparisons between groups were made and independent factors associated with physician acceptance were determined.

Results

A total of 503 interventions were included and 392 (77.9%) were accepted by physicians. Most interventions were on gastrointestinal agents (49.7%) and supplements (42.7%). The common reasons for deprescribing were: overduration of treatment (44.5%), unclear indication (23.9%) and the overdosage (20.7%). No significant differences were found between the reasons for deprescribing and acceptance by physicians. Use of <9 medications (OR 1.92, 95% CI 1.20 to 3.07), gastrointestinal agents (OR 3.46, 95% CI 1.06 to 11.26) and supplements (OR 3.20, 95% CI 1.06 to 9.69) were associated with higher physician acceptance (p<0.05).

Conclusions

In our cohort of hospitalised elderly, gastrointestinal agents and supplements were most commonly suggested by pharmacists to be deprescribed and at least three quarters of these interventions were accepted by physicians.

Nursing home team-care deprescribing study: a stepped-wedge randomised controlled trial protocol

INTRODUCTION

An ageing population has become an urgent concern for Asia in recent times. In nursing homes, polypharmacy has also become a compounding issue. Deprescribing practice is an evidence-based strategy to provide a better outcome in this group of patients; however, its implementation in nursing homes is often challenging, and prospective outcome data on deprescribing practice in the elderly is lacking. Our study assesses the implementation of team-care deprescribing to understand the benefits of this practice in geriatric setting and to explore the factors affecting deprescribing practice.

METHODS AND ANALYSIS

This multicentre prospective study consists of a prestudy interview questionnaire, and a preintervention and postintervention study to be conducted in the nursing home setting on residents at least 65 years old and on five or more medications. We will employ a cluster randomised stepped-wedge interventional design, based on a five-step (reviewing, checking, discussion, communication and documentation) team-care deprescribing practice coupled with the use of a deprescribing guide (consisting of Beers and STOPP criteria, as well as drug interaction checking), to assess the health and pharmacoeconomic outcome in nursing homes' practice. Primary outcome measures of the intervention will consist of fall risks using a fall risk assessment tool. Other outcomes assessed include fall rates, pill burden including number of pills per day, number of doses per day and number of medications prescribed. Cost-related measures will include the use of cost-benefit analysis, which is calculated from the medication cost savings from deprescribing. For the prestudy interview questionnaire, findings will be analysed qualitatively using thematic analysis.

ETHICS AND DISSEMINATION

This study is approved by the Domain Specific Review Board of National Healthcare Group, Singapore (2016/00422) and Monash University Human Research Ethics Committee (2016-1430-7791). The study findings shall be disseminated in international conferences and peer-reviewed publications. The study is registered with ClinicalTrials.gov (NCT02863341), Pre-results.

Deprescribing anticholinergic and sedative medicines: protocol for a Feasibility Trial (DEFEAT-polypharmacy) in residential aged care facilities

INTRODUCTION

Targeted deprescribing of anticholinergic and sedative medicines can lead to positive health outcomes in older people; as they have been associated with cognitive and physical functioning decline. This study will examine whether the proposed intervention is feasible at reducing the prescription of anticholinergic and sedative medicines in older people.

METHODS AND ANALYSIS

The Standard Protocol Items: Recommendations for Interventional trials (SPIRIT checklist) was used to develop and report the protocol. Single group (precomparison and postcomparison) feasibility study design.

STUDY POPULATION

3 residential care homes have been recruited.

INTERVENTION

This will involve a New Zealand registered pharmacist using peer-reviewed deprescribing guidelines, to recommend to general practitioners (GPs), sedative and anticholinergic medicines that can be deprescribed. The cumulative use of anticholinergic and sedative medicines for each participant will be quantified, using the Drug Burden Index (DBI).

OUTCOMES

The primary outcome will be the change in the participants' DBI total and DBI PRN 3 and 6 months after implementing the deprescribing intervention. Secondary outcomes will include the number of recommendations taken up by the GP, participants' cognitive functioning, depression, quality of life, activities of daily living and number of falls.

DATA COLLECTION POINTS

Participants' demographic and clinical data will be collected at the time of enrolment, along with the DBI. Outcome measures will be collected at the time of enrolment, 3 and 6 months' postenrolment.

ETHICS AND DISSEMINATION

Ethics approval has been granted by the Human Disability and Ethics Committee. Ethical approval number (16/NTA/61).

Deprescribing: A narrative review of the evidence and practical recommendations for recognizing opportunities and taking action

Deprescribing can be defined as the process of withdrawal or dose reduction of medications which are considered inappropriate in an individual. The aim of this narrative review is to provide an overview of "deprescribing"; firstly discussing the potential benefits and harms followed by the barriers to and enablers of deprescribing. We also provide practical recommendations to recognise opportunities and strategies for deprescribing in practice. Studies focused on minimizing polypharmacy indicate that deprescribing may be associated with potential benefits including resolution of adverse drug reactions, improved quality of life and medication adherence and a reduction in drug costs. While the data on the benefits is inconsistent, deprescribing appears to be safe. There are, however, potential harms including return of medical conditions or symptoms and adverse drug withdrawal reactions which emphasise the need for the process to be supervised and monitored by a health care professional. Taking action on deprescribing can be facilitated by knowledge of potential barriers, implementing a deprescribing process (utilising developed tools and resources) and identifying opportunities for deprescribing through engaging with patients and caregivers and other health care professionals and considering deprescribing in a variety of populations. Important areas for future research include the suitability of deprescribing of certain medications in specific populations, how to implement deprescribing processes into clinical care in a feasible and cost effective manner and how to engage consumers throughout the process to achieve positive health and quality of life outcomes.

Deprescribing: a new goal focused on the patient

It is estimated that one-fifth of adult patients are treated with polypharmacy (five or more drugs) and the prevalence of this phenomenon in the elderly is even higher, ranging from 30% to 70%, even reaching 90% in residents of residential aged care facilities. Polypharmacy in the elderly increases the risk of adverse reactions, inappropriate prescriptions, drug interactions, number of hospitalizations, costs, and even death. In a recent systematic review, the authors proposed defining deprescribing as 'the process of withdrawal of inappropriate medication supervised by a health care professional with the goal of managing polypharmacy and improving outcomes'.

The effect of pharmacists on ward rounds measured by the STOPP/START tool in a specialized geriatric unit

WHAT IS KNOWN AND OBJECTIVE

The STOPP/START tool has been validated to assess elderly patients for potentially inappropriate prescribing. This study aimed to assess the effect of inclusion of a pharmacist on a physician-led ward round on potentially inappropriate prescribing in hospitalized elderly patients.

METHODS

This was an observational study of prescribing for patients using the STOPP/START tool at three points during hospital stay; admission to hospital, on transfer to the specialized geriatric unit and on discharge from hospital. Data were collected over 4 months pre- and post-introduction of a pharmacist to a physician-led ward round. Demographic and clinical data, including total number of medications and STOPP/START criteria met, were collected. The mean number of STOPP/START criteria at each time-point was compared for pre- and post-introduction of a pharmacist using a Mann-Whitney U-test. The mean number of criteria for each time-point within each group was compared using a paired Student's t-test.

RESULTS AND DISCUSSION

The demographic characteristics of the participants in the pre- and post-intervention groups were similar. The post-intervention group had numerically less STOPP/START criteria, mean 1·18 (1·37) compared to the pre-intervention group 1·50 (1·41), P = 0·07 at discharge. The pre-intervention group had no significant change in the criteria from admission 1·78 (1·57) to geriatric unit transfer 1·72 (1·54) (P = 0·37); however, there was a significant decrease from geriatric unit transfer 1·72 (1·54) to discharge 1·50 (1·41) (P = 0·02). The post-intervention group had a significant decrease from hospital admission 2·30 (1·91) to geriatric unit transfer 1·59 (1·60) (P < 0·01) and again to discharge 1·18 (1·37) (P < 0·01).

WHAT IS NEW AND CONCLUSION

Pharmacist participation on the ward round in a specialized geriatric unit resulted in a numerical improvement in prescribing quality as measured by the STOPP/START tool.

The Ethics of Deprescribing in Older Adults

Deprescribing is the term used to describe the process of withdrawal of an inappropriate medication supervised by a clinician. This article presents a discussion of how the Four Principles of biomedical ethics (beneficence, non-maleficence, autonomy, and justice) that may guide medical practitioners' prescribing practices apply to deprescribing medications in older adults. The view of deprescribing as an act creates stronger moral duties than if viewed as an omission. This may explain the fear of negative outcomes which has been reported by prescribers as a barrier to deprescribing. Respecting the autonomy of older adults is complex as they may not wish to be active in the decision-making process; they may also have reduced cognitive function and family members may therefore have to step in as surrogate decision-makers. Informed consent is intended as a process of information giving and reflection, where consent can be withdrawn at any time. However, people are rarely updated on the altered risks and benefits of their long-term medications as they age. Cessation of inappropriate medication use has a large financial benefit to the individual and the community. However, the principle of justice also dictates equal rights to treatment regardless of age.
