Deprescription in elderly patients with type 2 diabetes mellitus

Deprescribing in Older Adults With Type 2 Diabetes: Associations With Patients' Perspectives: The Diabetes and Aging Study

BACKGROUND

Little is known about how patients' preferences, expectations, and beliefs (jointly referred to as perspectives) influence deprescribing. We evaluated the association of patients' self-reported perspectives with subsequent deprescribing of diabetes medications in older adults with type 2 diabetes.

METHODS

Longitudinal cohort study of 1629 pharmacologically treated adults ages 65-100 years with type 2 diabetes who received care at Kaiser Permanente of Northern California (KPNC) and participated in the Diabetes Preferences and Self-Care survey (2019). The survey asked questions about perspectives regarding the use of diabetes medications. Deprescribing was identified during the 24 months following the survey and defined as any of the following: discontinuation of one or more therapeutic classes, reduction in frequency of daily dosing, reduction in total daily pill count, or reduction in total daily dose for oral hypoglycemic agents. Rates of deprescribing and measures of relative risk were calculated for patients' perspectives and select clinical factors. Models predicting deprescribing were adjusted for age, sex, race/ethnicity, health literacy, baseline number of diabetes medications, duration of diabetes, overtreatment per Endocrine Society guidelines, and KPNC eligibility for targeted deprescribing and weighted to account for the age-stratified complex sampling design and survey response.

RESULTS

Six hundred seventy-three (38%) patients experienced deprescribing over a mean follow-up of 23 months. Deprescribing was significantly associated with the following patient perspectives: not expecting to need diabetes medication for life (RR = 1.48, 95% CI: 1.07-2.03) and not recognizing that taking fewer medications could lead to higher blood sugar levels (RR = 1.31, 95% CI: 1.09-1.58).

CONCLUSIONS

Patients' perspectives may enable or hinder deprescribing, emphasizing the importance of soliciting these perspectives during shared decision-making. Effective deprescribing will benefit from understanding patients' perspectives and fostering patient-provider communication about medication changes throughout the disease course.

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

AIMS

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

[Impact of a primary care pharmacy unit on the optimization of pharmacological treatment of type 2 diabetic patients]

OBJECTIVE

To evaluate the impact of a pharmaceutical intervention on treatment optimization in patients with type 2 diabetes mellitus.

DESIGN

Before-after intervention study. SITE: Health centers of the Primary Care Department of Camp de Tarragona.

PARTICIPANTS

Patients aged ≥ 18 years, diagnosed with type 2 diabetes mellitus and under treatment with antidiabetic drugs.

INTERVENTIONS

Review of pharmacological treatment for type 2 diabetes mellitus and issuance of proposals for its adequacy.

MAIN MEASUREMENTS

Demographic and clinical variables were collected to assess the adequacy of antidiabetic treatment. A consensus meeting was arranged with the patients' primary care physician to evaluate the proposals for improvement. The implementation of the proposals and the variation in postintervention glycemic control were assessed.

RESULTS

A total of 907 patients (59% men) were included. A total of 782 proposals for intervention were made in 65.8% of the patients reviewed. Of the proposals, 43.5% corresponded to drug discontinuation, 16% to intensification of dosing and 12.6% to exchange for a therapeutic equivalent. Of the consensual proposals, 54.7% were implemented. HbA1c was reduced by 0.2% after the intervention (7.4 vs 7.2%).

CONCLUSIONS

Review of the pharmacological treatment of patients with type 2 diabetes mellitus by a pharmacist or pharmacologist facilitates its optimization.

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.

Potential Risk of Overtreatment in Patients with Type 2 Diabetes Aged 75 Years or Older: Data from a Population Database in Catalonia, Spain

Aim: To assess the potential risk of overtreatment in patients with type 2 diabetes (T2DM) aged 75 years or older in primary care. Methods: Electronic health records retrieved from the SIDIAP database (Catalonia, Spain) in 2016. Variables: age, gender, body mass index, registered hypoglycemia, last HbA1c and glomerular filtration rates, and prescriptions for antidiabetic drugs. Potential overtreatment was defined as having HbA1c < 7% or HbA1c < 6.5% in older patients treated with insulin, sulfonylureas, or glinides. Results: From a total population of 138,374 T2DM patients aged 75 years or older, 123,515 had at least one HbA1c available. An HbA1c below 7.0% was present in 59.1% of patients, and below 6.5% in 37.7%. Overall, 23.0% of patients were treated with insulin, 17.8% with sulfonylureas, and 6.6% with glinides. Potential overtreatment (HbA1c < 7%) was suspected in 26.6% of patients treated with any high-risk drug, 47.8% with sulfonylureas, 43.5% with glinides, and 28.1% with insulin. Using the threshold of HbA1c < 6.5%, these figures were: 21.6%, 24.4%, 17.9%, and 12.3%, respectively. Conclusion: One in four older adults with T2DM treated with antidiabetic drugs associated with a high risk of hypoglycemia might be at risk of overtreatment. This risk is higher in those treated with sulfonylureas or glinides than with insulin.

Effects of resveratrol therapy on glucose metabolism, insulin resistance, inflammation, and renal function in the elderly patients with type 2 diabetes mellitus: A randomized controlled clinical trial protocol

BACKGROUND

Diabetes mellitus is a spectrum of metabolic disorders characterized by hyperglycemia and shows a growing global public health problem in the elderly. Resveratrol presents antiaging, anti-inflammatory, antitumor antioxidant, and cardioprotective activities. The purpose of this study was to investigate the ameliorative effects of resveratrol on blood glucose, insulin metabolism, lipid profile, renal function, inflammation, and nutrient sensing systems in the elderly patients with type 2 diabetes mellitus.

METHODS

The study is a single-blind, parallel-group, randomized controlled clinical trial consisting of a 6-month treatment period. A total of 472 elderly patients with type 2 diabetes mellitus were enrolled, and included participants will be randomized into 2 groups: resveratrol (n = 242) and placebo (n = 230). The clinical efficacy and changes in clinical parameters in each group will be measured at the indicated time. Clinical parameters included blood glucose, insulin resistance index, blood lipid index, proinflammatory cytokines, renal function, and nutrient sensing systems.

RESULTS

Resveratrol treatment greatly improved glucose metabolism, insulin tolerance, and insulin metabolism compared to placebo. Resveratrol relieved symptoms through enhancing nutrient sensing systems, which in turn reduced production and activity of glucose-6-phosphatase. Compared with placebo, resveratrol treatment significantly decreased proinflammatory cytokines glycated hemoglobin/hemoglobin A1c, interleukin-6, tumor necrosis factor-alpha, and interleukin-1beta in the elderly diabetes. Resveratrol treatment decreased blood glucose parameters, improved the lipid profile (total cholesterol, low-density lipoprotein, high-density lipoprotein, and triglycerides), and renal function compared to placebo.

CONCLUSION

In conclusion, resveratrol treatment improves inflammation, renal function, blood glucose parameters, inflammation, insulin resistance, and nutrient sensing systems in the elderly patients with type 2 diabetes mellitus, indicating resveratrol may be a potential therapeutic drug for the treatment of the elderly patients with type 2 diabetes mellitus.

Barriers and Enablers of Healthcare Providers to Deprescribe Cardiometabolic Medication in Older Patients: A Focus Group Study

Introduction

Benefits and risks of preventive medication change over time for ageing patients and deprescribing of medication may be needed. Deprescribing of cardiovascular and antidiabetic drugs can be challenging and is not widely implemented in daily practice.

Objective

The aim of this study was to identify barriers and enablers of deprescribing cardiometabolic medication as seen by healthcare providers (HCPs) of different disciplines, and to explore their views on their specific roles in the process of deprescribing.

Methods

Three focus groups with five general practitioners, eight pharmacists, three nurse practitioners, two geriatricians, and two elder care physicians were conducted in three cities in The Netherlands. Interviews were recorded and transcribed verbatim. Directed content analysis was performed on the basis of the Theoretical Domains Framework. Two researchers independently coded the data.

Results

Most HCPs agreed that deprescribing of cardiometabolic medication is relevant but that barriers include lack of evidence and expertise, negative beliefs and fears, poor communication and collaboration between HCPs, and lack of resources. Having a guideline was considered an enabler for the process of deprescribing of cardiometabolic medication. Some HCPs feared the consequences of discontinuing cardiovascular or antidiabetic medication, while others were not motivated to deprescribe when the patients experienced no problems with their medication. HCPs of all disciplines stated that adequate patient communication and involving the patients and relatives in the decision making enables deprescribing. Barriers to deprescribing included the use of medication initiated by specialists, the poor exchange of information, and the amount of time it takes to deprescribe cardiometabolic medication. The HCPs were uncertain about each other’s roles and responsibilities. A multidisciplinary approach including the pharmacist and nurse practitioner was seen as the best way to support the process of deprescribing and address barriers related to resources.

Conclusion

HCPs recognized the importance of deprescribing cardiometabolic medication as a medical decision that can only be made in close cooperation with the patient. To successfully accomplish the process of deprescribing they strongly recommended a multidisciplinary approach.
