A Qualitative Study of Perspectives of Older Adults on Deintensifying Diabetes Medications

Perspectives on deprescribing in older people with type 2 diabetes and/or cardiovascular conditions: challenges from healthcare provider, patient and caregiver perspective, and interventions to support a proactive approach

INTRODUCTION

For people with type 2 diabetes and/or cardiovascular conditions, deprescribing of glucose-lowering, blood pressure-lowering and/or lipid-lowering medication is recommended when they age, and their health status deteriorates. So far, deprescribing rates of these so-called cardiometabolic medications are low. A review of challenges and interventions addressing these challenges in this population is pertinent.

AREAS COVERED

We first provide an overview of relevant deprescribing recommendations. Next, we review challenges for healthcare providers (HCPs) to deprescribe cardiometabolic medication and provide insight in the patient and caregiver perspective on deprescribing. We summarize findings from research on implementing deprescribing of cardiometabolic medication and reflect on strategies to enhance deprescribing. We have used a combination of methods to search for relevant articles.

EXPERT OPINION

There is a need for rigorous development and evaluation of intervention strategies aimed at proactive deprescribing of cardiometabolic medication. To address challenges at different levels, these should be multifaceted interventions. All stakeholders must become aware of the relevance of deintensifying medication in this population. Education and training for HCPs and patients should support patient-centered communication and shared decision-making. Development of procedures and tools to select eligible patients and conduct targeted medication reviews are important for implementation of deprescribing in routine care.

Willingness to take less medication for type 2 diabetes among older patients: The Diabetes & Aging Study

BACKGROUND

To examine the willingness of older patients to take less diabetes medication (de-intensify) and to identify characteristics associated with willingness to de-intensify treatment.

METHODS

Survey conducted in 2019 in an age-stratified, random sample of older (65-100 years) adults with diabetes on glucose-lowering medications in the Kaiser Permanente Northern California Diabetes Registry. We classified survey responses to the question: "I would be willing to take less medication for my diabetes" as willing, neutral, or unwilling to de-intensify. Willingness to de-intensify treatment was examined by several clinical characteristics, including American Diabetes Association (ADA) health status categories used for individualizing glycemic targets. Analyses were weighted to account for over-sampling of older individuals.

RESULTS

A total of 1337 older adults on glucose-lowering medication(s) were included (age 74.2 ± 6.0 years, 44% female, 54.4% non-Hispanic white). The proportions of participants willing, neutral, or unwilling to take less medication were 51.2%, 27.3%, and 21.5%, respectively. Proportions of willing to take less medication varied by age (65-74 years: 54.2% vs. 85+ years: 38.5%) and duration of diabetes (0-4 years: 61.0% vs. 15+ years: 44.2%), both p < 0.001. Patients on 1-2 medications were more willing to take less medication(s) compared with patients on 10+ medications (62.1% vs. 46.6%, p = 0.03). Similar proportions of willingness to take less medications were seen across ADA health status, and HbA1c. Willingness to take less medication(s) was similar across survey responses to questions about patient-clinician relationships.

CONCLUSIONS

Clinical guidelines suggest considering treatment de-intensification in older patients with longer duration of diabetes, yet patients with these characteristics are less likely to be willing to take less medication(s).

Deprescribing in older adults with polypharmacy

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

A National Survey of Physicians' Views on the Importance and Implementation of Deintensifying Diabetes Medications

BACKGROUND

Guidelines recommend deintensifying hypoglycemia-causing medications for older adults with diabetes whose hemoglobin A1c is below their individualized target, but this rarely occurs in practice.

OBJECTIVE

To understand physicians' decision-making around deintensifying diabetes treatment.

DESIGN

National physician survey.

PARTICIPANTS

US physicians in general medicine, geriatrics, or endocrinology providing outpatient diabetes care.

MAIN MEASURES

Physicians rated the importance of deintensifying diabetes medications for older adults with type 2 diabetes, and of switching medication classes, on 5-point Likert scales. They reported the frequency of these actions for their patients, and listed important barriers and facilitators. We evaluated the independent association between physicians' professional and practice characteristics and the importance of deintensifying and switching diabetes medications using multivariable ordered logistic regression models.

KEY RESULTS

There were 445 eligible respondents (response rate 37.5%). The majority of physicians viewed deintensifying (80%) and switching (92%) diabetes medications as important or very important to the care of older adults. Despite this, one-third of physicians reported deintensifying diabetes medications rarely or never. While most physicians recognized multiple reasons to deintensify, two-thirds of physicians reported barriers of short-term hyperglycemia and patient reluctance to change medications or allow higher glucose levels. In multivariable models, geriatricians rated deintensification as more important compared to other specialties (p=0.027), and endocrinologists rated switching as more important compared to other specialties (p<0.006). Physicians with fewer years in practice rated higher importance of deintensification (p<0.001) and switching (p=0.003).

CONCLUSIONS

While most US physicians viewed deintensifying and switching diabetes medications as important for the care of older adults, they deintensified infrequently. Physicians had ambivalence about the relative benefits and harms of deintensification and viewed it as a potential source of conflict with their patients. These factors likely contribute to clinical inertia, and studies focused on improving shared decision-making around deintensifying diabetes medications are needed.

Barriers and Enablers for Deprescribing Glucose-Lowering Treatment in Older Adults: A Systematic Review

OBJECTIVES

Overtreatment with glucose-lowering treatment (GLT) is frequent and a source of high morbidity and mortality in older adults with type 2 diabetes mellitus (T2DM). This study aimed to identify and synthesize barriers and enablers for deprescribing GLT in older adults (≥65 years) with T2DM.

DESIGN

Systematic review of qualitative and mixed-methods studies.

SETTING AND PARTICIPANTS

Older adults with T2DM, any participants [patients, health care providers (HCPs), caregivers], any settings.

METHODS

Two researchers (and a referred third researcher at all stages) independently screened original articles reporting qualitative and mixed-methods studies exploring barriers and enablers for deprescribing GLT in older adults published during 2010-2023, identified from MEDLINE, Embase, CINAHL, and gray literature. Quality of the included studies was assessed with the Mixed-Methods Appraisal Tool. Verbatim statements on barriers and enablers were extracted, and determinants of behaviors were identified with the Theoretical Domains Framework (TDF) version 2, and related intervention functions (targets for future interventions) were proposed according to the Behavior Change Wheel (BCW).

RESULTS

We identified only 4 studies from 2 countries (United States and the Netherlands), all recently published (2019-2023), that primarily reported barriers to GLT deprescribing from interviews or focus groups of patients or HCPs practicing outpatient medicine. Knowledge, fear, poor communication, inertia, and trust with HCPs were the main determinants of behaviors that influenced deprescribing, and education, training, persuasion and environmental restructuring were the main intervention functions for proposing future interventions. Studies did not cover financial aspects, physician characteristics, or caregiver and family viewpoints.

CONCLUSIONS AND IMPLICATIONS

The use of a behavioral theory and a validated implementation framework provided a comprehensive approach to identifying barriers and enablers for deprescribing GLT in older adults (≥65 years) with T2DM. The behavioral determinants identified may be useful in tailoring interventions to improve the implementation of GLT deprescribing in older adults in ambulatory settings.
