Why This Research Matters
This research project, funded by the National Institute on Aging (NIA), aims to investigate a significant concern in long-term care: the widespread and often off-label use of antiepileptic drugs (AEDs) among patients with dementia residing in nursing homes. The study highlights that these medications, such as valproic acid and gabapentin, are frequently prescribed for symptoms like behavioral disturbances or pain, even though their effectiveness for these conditions is not well-established by scientific evidence. This practice has raised alarms due to the potential serious side effects associated with AEDs in older adults, including increased risk of falls, sedation, and mortality.
The research project outlines three main aims. Firstly (Aim 1), it seeks to characterize a range of factors linked to AED prescribing among Medicare beneficiaries who have dementia and live in nursing homes. These factors encompass patient-specific characteristics, the attributes of their healthcare providers, and features of the nursing home facilities themselves. Secondly (Aim 2), the study plans to analyze clinical outcomes for residents when they are prescribed AEDs compared to alternative medication classes like antipsychotics or opioids. This will involve examining important health indicators such as mortality rates and changes in behavioral scores or pain levels, using data from Medicare and Minimum Data Set records linked together. Thirdly (Aim 3), the researchers intend to conduct interviews with prescribing clinicians, nurses, and medical directors at both high- and low-AED-prescribing facilities. These qualitative discussions will aim to uncover the underlying reasons for these prescribing patterns, including the specific indications for using AEDs and the attitudes of healthcare professionals towards them.
For nursing students, this research project underscores several critical points about geriatric care and medication management in complex settings like long-term care. It brings attention to a potential overuse of medications that carry significant risks when safer or more appropriate alternatives might exist. Students should learn to critically appraise how medication decisions are made in such environments, considering not just the efficacy of drugs but also their safety profile and patient-centeredness. The study's mixed-methods approach—combining quantitative data analysis with qualitative interviews—is a valuable model for understanding multifaceted healthcare problems. It demonstrates that effective solutions often require looking beyond simple drug lists to understand the human factors influencing prescribing behaviors, such as clinician beliefs, facility policies, and resident-specific needs.
When using this source, students should be aware that it primarily provides abstract-level information from a research project proposal rather than presenting final results or conclusions. The document outlines the aims, methodology, and rationale for investigating AED use in nursing homes with dementia patients but does not report on completed studies or definitive findings. Therefore, any claims about specific outcomes, prevalence rates, sample sizes, or author-concluded statements should be understood as part of the research plan rather than established facts from this source alone.
Source abstract
Study Overview
PROJECT ABSTRACT Nursing homes are an important location of care for patients with dementia, who are at high risk for medication-related harms. Antiepileptic medications such as valproic acid and gabapentin are commonly prescribed off-label to patients with dementia to treat symptoms such as behavioral disturbances and pain despite limited evidence that these medications are effective in treating such conditions. Our work has found that the prescribing of antiepileptics has doubled over the past decade, now prescribed to over 40% of nursing home residents with dementia. The growth in antiepileptic prescribing is largely driven by valproic acid and gabapentin, which are potentially prescribed as substitutes for antipsychotics or opioids, respectively, in light of federal nursing home prescribing initiatives to reduce antipsychotic use and the ongoing opioid epidemic. However, unlike antipsychotic and opioid prescribing, use of antiepileptics is not subject to regulatory oversight and growth has continued largely unchecked. Off-label use of antiepileptics is concerning for older adults given serious associated risks including falls, sedation, and increased mortality. Despite the high rates of antiepileptic prescribing to nursing home residents with dementia and potential harms associated with use, this growth in prescribing has received little attention. Reducing potentially inappropriate antiepileptic use is an opportunity to improve medication safety for nursing home residents with dementia, both through identifying which nursing home residents are at greatest risk as well as the role of clinicians and facilities in these prescribing shifts. However, the design of clinical or policy interventions to reduce potentially inappropriate antiepileptic prescribing cannot occur without understanding why clinicians decide to prescribe these medications. In this explanatory mixed-methods analysis, we will first characterize the array of patient, provider, and nursing home facility characteristics associated with antiepileptic prescribing among all Medicare beneficiaries with dementia residing in nursing homes (Aim 1). Next, in Aim 2, we will use linked Medicare and Minimum Data Set data to examine clinical outcomes associated with antiepileptic medication initiation (e.g., mortality, change in behavioral and pain scores) as compared to alternative medication classes (i.e., antipsychotics and opioids). Finally, in Aim 3 we will interview prescribing clinicians, nurses, and medical directors at high and low antiepileptic prescribing facilities to determine the key drivers, indications, and attitudes towards antiepileptic use. With input from a multidisciplinary Expert Panel including a patient with early dementia and caregiver dyad, we will identify remaining knowledge gaps and potential prescribing intervention targets. Findings will address a major gap in our knowledge of the drivers and safety of off-label antiepileptic use and help identify possible intervention targets to improve nursing home prescribing safety for residents with dementia.

Frequently asked questions
What is the main focus of this research project?
The main focus of this National Institute on Aging-funded research project (NIH Grant 5R01AG087073-02) is to study antiepileptic medication use among patients with dementia in long-term care settings, specifically examining its growth, drivers, and safety implications.
Why are antiepileptics like valproic acid and gabapentin being prescribed more frequently?
The abstract indicates that the growth in antiepileptic prescribing is largely driven by their use as potential substitutes for antipsychotics or opioids. This shift may be influenced by federal nursing home prescribing initiatives aimed at reducing antipsychotic use and addressing the ongoing opioid epidemic.
What are some of the concerns associated with off-label antiepileptic use in older adults?
Off-label use of antiepileptics is concerning for older adults due to serious potential harms, including falls, sedation, and increased mortality. The abstract highlights these risks as significant considerations given the high rates of prescribing.
What specific aims does this research project have regarding antiepileptic prescribing?
The project has three main aims: 1) To characterize patient, provider, and nursing home facility characteristics associated with antiepileptic prescribing. 2) To examine clinical outcomes (e.g., mortality, change in behavioral/pain scores) of antiepileptic initiation compared to alternatives like antipsychotics or opioids using linked Medicare data. 3) To interview clinicians about their drivers, indications, and attitudes towards antiepileptic use.
What is the current prevalence of antiepileptic prescribing among nursing home residents with dementia?
The abstract states that our work has found that the prescribing of antiepileptics to patients with dementia in long-term care settings has doubled over the past decade, and now prescribes these medications to over 40% of such residents.
What is the role of regulatory oversight for antiepileptic use compared to other medication classes?
Unlike prescribing of antipsychotics or opioids, which are subject to certain federal nursing home initiatives aimed at reducing their use (e.g., antipsychotic reduction programs), the growth in antiepileptic prescribing has continued largely unchecked due to a lack of similar regulatory oversight.
What is one potential reason for substituting antipsychotics with valproic acid?
One potential reason mentioned in the abstract for substituting antipsychotics with valproic acid (an antiepileptic) could be related to federal nursing home prescribing initiatives aimed at reducing antipsychotic use.
What is one potential reason for substituting opioids with gabapentin?
The abstract suggests that gabapentin, another antiepileptic, might be used as a substitute for opioids in light of the ongoing opioid epidemic and related federal nursing home prescribing initiatives to reduce opioid use.
Who are some key stakeholders involved in this research project's design?
A multidisciplinary Expert Panel is mentioned in the abstract. This panel includes clinicians (prescribing, nurses, medical directors), researchers, and importantly, a patient with early dementia and caregiver dyad, whose input helps identify knowledge gaps and potential intervention targets.
What are some of the clinical outcomes being investigated when antiepileptics are initiated?
The research project aims to examine several clinical outcomes associated with initiating antiepileptic medication. These include mortality rates and changes in behavioral scores (e.g., for agitation, aggression) as well as pain scores.
