Interventions to deprescribe potentially inappropriate medications in the elderly: Lost in translation?

Implementation considerations of deprescribing interventions: A scoping review

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

Polypharmacy and Deprescribing in Older Adults

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

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.

Challenges and opportunities in creating a deprescribing program in the emergency department: A qualitative study

BACKGROUND

As the population of older adults increases, appropriate deprescribing becomes increasingly important for emergency geriatric care. Older adults represent the sickest patients with chronic medical conditions, and they are often exposed to high-risk medications. We need to provide an evidence-based, standardized deprescribing program in the acute care setting, yet the evidence base is lacking and standardized medication programs are needed.

METHODS

We conducted a qualitative study with the goal to understand the perspective of healthcare workers, patients, and caregivers on deprescribing high-risk medications in the context of emergency care practices, provider preferences, and practice variability, along with the facilitators and barriers to an effective deprescribing program in the emergency department (ED). To ensure rich, contextual data, the study utilized two qualitative methods: (1) a focus group with physicians, advanced practice providers, nurses, pharmacists, and geriatricians involved in care of older adults and their prescriptions in the acute care setting; (2) semi-structured interviews with patients and caregivers involved in treatment and emergency care. Transcriptions were coded using thematic content analysis, and the principal investigator (S.L.) and trained research staff categorized each code into themes.

RESULTS

Data collection from a focus group with healthcare workers (n = 8) and semi-structured interviews with patients and caregivers (n = 20) provided evidence of a potentially promising ED medication program, aligned with the vision of comprehensive care of older adults, that can be used to evaluate practices and develop interventions. We identified four themes: (1) Challenges in medication history taking, (2) missed opportunities in identifying high-risk medications, (3) facilitators and barriers to deprescribing recommendations, and (4) how to coordinate deprescribing recommendations.

CONCLUSIONS

Our focus group and semi-structured interviews resulted in a framework for an ED medication program to screen, identify, and deprescribe high-risk medications for older adults and coordinate their care with primary care providers.

Use of the consolidated framework for implementation research in a mixed methods evaluation of the EQUIPPED medication safety program in four academic health system emergency departments

Background

Enhancing Quality of Prescribing Practices for Older Adults Discharged from the Emergency Department (EQUIPPED) is an effective quality improvement program initially designed in the Veterans Administration (VA) health care system to reduce potentially inappropriate medication prescribing for adults aged 65 years and older. This study examined factors that influence implementation of EQUIPPED in EDs from four distinct, non-VA academic health systems using a convergent mixed methods design that operationalized the Consolidated Framework for Implementation Research (CFIR). Fidelity of delivery served as the primary implementation outcome.

Materials and methods

Four EDs implemented EQUIPPED sequentially from 2017 to 2021. Using program records, we scored each ED on a 12-point fidelity index calculated by adding the scores (1-3) for each of four components of the EQUIPPED program: provider receipt of didactic education, one-on-one academic detailing, monthly provider feedback reports, and use of order sets. We comparatively analyzed qualitative data from focus groups with each of the four implementation teams (n = 22) and data from CFIR-based surveys of ED providers (108/234, response rate of 46.2%) to identify CFIR constructs that distinguished EDs with higher vs. lower levels of implementation.

Results

Overall, three sites demonstrated higher levels of implementation (scoring 8-9 of 12) and one ED exhibited a lower level (scoring 5 of 12). Two constructs distinguished between levels of implementation as measured through both quantitative and qualitative approaches: patient needs and resources, and organizational culture. Implementation climate distinguished level of implementation in the qualitative analysis only. Networks and communication, and leadership engagement distinguished level of implementation in the quantitative analysis only.

Discussion

Using CFIR, we demonstrate how a range of factors influence a critical implementation outcome and build an evidence-based approach on how to prime an organizational setting, such as an academic health system ED, for successful implementation.

Conclusion

This study provides insights into implementation of evidence-informed programs targeting medication safety in ED settings and serves as a potential model for how to integrate theory-based qualitative and quantitative methods in implementation studies.

Using the behavior change wheel to link published deprescribing strategies to identified local primary healthcare needs

BACKGROUND

Polypharmacy is a major global problem. Evidence in primary care shows deprescribing can be beneficial. Behaviour change theories such as the Theoretical Domains Framework (TDF) and the Behaviour Change Wheel (BCW) can help develop successful implementation of deprescribing initiatives.

OBJECTIVES

To link locally identified deprescribing influencers with components of successfully trialed deprescribing strategies, with the aim of informing the development of local deprescribing initiatives.

METHODS

Two background studies were completed. A qualitative study of interviews and focus groups identified influencers of deprescribing from local primary care physicians, nurse practitioners, and pharmacists. Transcripts were coded using the TDF and mapped to the Intervention Functions of the BCW. A scoping review identified studies that investigated primary care deprescribing strategies, which were mapped to the BCW Intervention Functions and the Behaviour Change Techniques (BCTs). For this analysis, six main TDF domains from the qualitative study were linked to the BCTs identified in the scoping review through the Intervention Functions of the BCW.

RESULTS

Within the BCW component Capability, one TDF domain identified in the qualitative study, Memory, Attention and Decision Process, was linked to strategies like academic detailing from the scoping review. For the Opportunity component, two TDF domains, Social Influences and Environmental Context and Resources, were linked to strategies such as pharmacist medication reviews, providing patient information leaflets, and evidence-based deprescribing tools. For the Motivation component, three TDF domains, Social/Professional Role and Identity, Intentions, and Beliefs about Consequences, were linked to strategies such as sending deprescribing information to prescribers, using tools to identify eligible patients, and having patients report adverse events of medications.

CONCLUSIONS

This analysis identified deprescribing strategies that can be used to address influencers related to behaviour change from the perspective of primary care providers, and to assist with future deprescribing initiative development and implementation in the local context.

Development of video animations to encourage patient-driven deprescribing: A Team Alice Study

OBJECTIVE

Patient-driven deprescribing initiatives aim to increase patient knowledge and strengthen self-advocacy skills. This article describes the development of three animated videos designed to educate older adults about unsafe prescribing and medication harm, based on the actionable lessons from the death, by polypharmacy, of an older adult in our community.

METHODS

Using a community based participatory research approach (CBPR), members of three senior centers (n = 53) and the Deprescribing Partnership of Western New York (n = 30) were recruited and participated in two rounds of focus groups to guide the video development.

RESULTS

Stakeholder input led to changes in content, wording, and visual presentation. The final versions of the videos emphasize the following messages (1) "New medications and what you should know about the risks", (2) "What you should do when a doctor tells you never to take a certain medication", (3) "What you should know about medications when you are in the hospital."

CONCLUSION

The study highlights the successful process of using CBPR to develop a series of videos designed to provide information on the risks of polypharmacy, and empower older adults to advocate for themselves.

PRACTICE IMPLICATIONS

Animated educational videos are a novel strategy to address medication harm in older adults. This research is a critical first step to increasing patient-led discussions that reduce the incidence of medication harm and inappropriate medication use among older adults.

Implementation of an animated medication information tool in community pharmacies, with a special focus on patients with limited health literacy

OBJECTIVES

The animated medication information tool 'Watchyourmeds' provides information in an accessible manner through animated videos and therefore appears to be especially suitable for people with limited health literacy. This study aimed to assess the implementation of this animated medication information tool in Dutch community pharmacies, with a special focus on patients with limited health literacy.

METHODS

A cross-sectional survey based on the Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework was sent to approximately 75% of the ±1900 community pharmacies in the Netherlands through email newsletters of pharmacy networks.

KEY FINDINGS

140 pharmacists (⁓10%) completed the survey and 125 of them (89%) indicated that they offered the animated medication information tool to their patients. 108 pharmacists indicated that the tool was offered to all patients, not only to patients with limited health literacy. The distribution method was primarily passive (patients were given a leaflet and were not explicitly pointed to or informed about the tool). Two frequently cited motivations for offering the tool were that it complemented other sources of information and that the health insurer provided a financial incentive. The main reasons patients refused to use the tool were that they had no access to or no affinity for the required technology.

CONCLUSIONS

This study demonstrated that the tool is used in community pharmacies and that it is offered to all patients, regardless of their presumed health literacy level. A more active method of offering the tool may be warranted to better reach patients with limited health literacy.

Leveraging implementation science to increase the translation of deprescribing evidence into practice

Implementation science may address some of the limitations that impede the translation of deprescribing recommendations into practice and policy. Application of principles and standard terminologies from implementation science could improve understanding and interpretation of deprescribing research findings. As such, in this commentary we propose three main avenues to help achieve this. These include: The application of these concepts derived from implementation science could help inform future deprescribing needs for clinicians and researchers. Ultimately, this could help ensure the quality use of medications and examination of meaningful outcomes in deprescribing studies. This could result in more consistent and widespread translation of deprescribing evidence into practice and policy across various healthcare settings.

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.

Medication Use Quality and Safety in Older Adults: 2019 Update

Improving the quality of medication use and medication safety are important priorities for prescribers who care for older adults. The objective of this article was to identify four exemplary articles with this focus in 2019. We selected high-quality studies that moved the field of research forward and were not merely replication studies. The chosen articles cover domains related to aspects of suboptimal prescribing and medication safety. The first study used a nationally representative sample of Medicare beneficiaries to examine the continuation of medications with limited benefit in patients admitted for cancer and non-cancer diagnoses in hospice (domain: potentially inappropriate medications). The second study, a retrospective cohort study of older adults in Ontario, Canada, assessed the association between prescribing oral anticoagulants in an emergency department relative to not prescribing anticoagulants in the emergency department and their persistence at 6 months (domain: underuse of medications). The third study, a cluster randomized trial in Quebec, Canada, evaluated the effect of conducting electronic medication reconciliation on several outcomes including adverse drug events and medication discrepancies (domain: medication safety). Lastly, the fourth study, a retrospective study using national inpatient and outpatient Veteran Health Administration combined with clinical and Medicare Claims data, examined the effects of intensification of antihypertensive medications on older adults' likelihood for hospital re-admission and other important clinical outcomes (domain: medication safety). Collectively, this review succinctly highlights pertinent topics related to promoting safe use of medications and promotes awareness of optimizing older adults' medication regimens.

Drug compliance and the Morisky Adherence Scale: An expression of concern and a warning

WHAT IS KNOWN AND OBJECTIVE

Every prescriber knows that patients often do not take their medicines as prescribed. Hippocrates, the wise man of Kos, knew over two millennia ago. Our objective is to comment on the types of studies aimed at understanding and optimizing drug usage and to draw attention to the need to seek approval before using or citing the Morisky adherence scale.

COMMENT

The study of prescribing and how patients use their medicines is important. As part of this effort, the results of investigations of how patients adhere to drug prescriptions can be informative. However, the results are meaningful only if the methods used for doing the measurements are valid and made explicit. We were surprised when a team of our authors were threatened with legal action for citing the Morisky Adherence Scale and explaining how some authors had obtained their adherence scores. Adherence studies are but one facet of the study of prescribing aimed at improving clinical outcomes. Other aspects include investigating the quality of prescribing, and how unnecessary medicines can be deprescribed to improve the quality of care and reduce the risk of adverse effects.

WHAT IS NEW AND CONCLUSION

The study of optimal prescribing is an important endeavour and adherence studies are but one aspect. We report that using and citing the Morisky Adherence scale in any detail is a risky business. Prior approval is required unless one is prepared to pay up, retrospectively. We require all authors to certify they have no conflicts of interest with respect to the scale.

Drug-Drug Interactions and Prescription Appropriateness in Patients with COVID-19: A Retrospective Analysis from a Reference Hospital in Northern Italy

Background

Patients hospitalised with severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2; coronavirus 2019 disease (COVID-19)] infection are frequently older with co-morbidities and receiving polypharmacy, all of which are known risk factors for drug–drug interactions (DDIs). The pharmacological burden may be further aggravated by the addition of treatments for COVID-19.

Objective

The aim of this study was to assess the risk of potential DDIs upon admission and during hospitalisation in patients with COVID-19 treated at our hospital.

Methods

We retrospectively analysed 502 patients with COVID-19 (mean age 61 ± 16 years, range 15–99) treated at our hospital with a proven diagnosis of SARS-CoV-2 infection hospitalised between 21 February and 30 April 2020 and treated with at least two drugs.

Results

Overall, 68% of our patients with COVID-19 were exposed to at least one potential DDI, and 55% were exposed to at least one potentially severe DDI. The proportion of patients experiencing potentially severe DDIs increased from 22% upon admission to 80% during hospitalisation. Furosemide, amiodarone and quetiapine were the main drivers of potentially severe DDIs upon admission, and hydroxychloroquine and particularly lopinavir/ritonavir were the main drivers during hospitalisation. The majority of potentially severe DDIs carried an increased risk of cardiotoxicity. No potentially severe DDIs were identified in relation to tocilizumab and remdesivir.

Conclusions

Among hospitalised patients with COVID-19, concomitant treatment with lopinavir/ritonavir and hydroxychloroquine led to a dramatic increase in the number of potentially severe DDIs. Given the high risk of cardiotoxicity and the scant and conflicting data concerning their efficacy in treating SARS-CoV-2 infection, the use of lopinavir/ritonavir and hydroxychloroquine in patients with COVID-19 with polypharmacy needs to be carefully considered.

Opportunities and Recommendations for Improving Medication Safety: Understanding the Medication Management System in Primary Care Through an Abstraction Hierarchy

Background

Despite making great strides in improving the treatment of diseases, the minimization of unintended harm by medication therapy continues to be a major hurdle facing the health care system. Medication error and prescription of potentially inappropriate medications (PIMs) represent a prevalent source of harm to patients and are associated with increased rates of adverse events, hospitalizations, and increased health care costs. Attempts to improve medication management systems in primary care have had mixed results. Implementation of new interventions is difficult because of complex contextual factors within the health care system. Abstraction hierarchy (AH), the first step in cognitive work analysis (CWA), is used by human factors practitioners to describe complex sociotechnical systems. Although initially intended for the nuclear power domain and interface design, AH has been used successfully to aid the redesign of numerous health care systems such as the design of decision support tools, mobile patient monitoring apps, and a telephone triage system.

Objective

This paper aims to refine our understanding of the primary care office in relation to a patient’s medication through the development of an AH. Emphasis was placed on the elements related to medication safety to provide guidance for the design of a safer medication management system in primary care.

Methods

The AH development was guided by the methodology used by seminal CWA literature. It was initially developed by 2 authors and later fine-tuned by an expert panel of clinicians, social scientists, and a human factors engineer. It was subsequently refined until an agreement was reached. A means-ends analysis was performed and described for the nodes of interest. The model represents the primary care office space through functional purposes, values and priorities, function-related purposes, object-related processes, and physical objects.

Results

This model depicts the medication management system at various levels of abstraction. The resulting components must be balanced and coordinated to provide medical treatment with limited health care resources. Understanding the physical and informational constraints on activities that occur in a primary care office depicted in the AH defines areas in which medication safety can be improved.

Conclusions

Numerous means-ends relationships were identified and analyzed. These can be further evaluated depending on the specific needs of the user. Recommendations for optimizing a medication management system in a primary care facility were made. Individual practices can use AH for clinical redesign to improve prescribing and deprescribing practices.
