Clinical Trial Summary

Anticipated Impact on Veterans Healthcare: Polypharmacy, defined as more than five medications, and hyperpolypharmacy, defined as more than 10 medications, are both common in older patients discharged to nursing homes for short stays. Several recent studies demonstrate the occurrence and potential inappropriateness of polypharmacy among older patients in both VA and non-VA healthcare settings. Other studies have shown that polypharmacy can lead to many harmful events among older community-dwelling and hospitalized populations including decreased medication taking, increased harm due to medications, and increased health care use and costs. Polypharmacy and a ways to measure drug burden have additionally been found to be associated with the development of the following geriatric syndromes: mild dementia, delirium, falls, loss of urine, and unintentional weight loss. The investigators' innovative, patient-centered Drug Reduction in Older Patients (DROP) procedure has significant potential to impact the health of a large population of older Veterans who are vulnerable to poor health outcomes. It is during hospitalization and nursing home care that older patients often acquire new geriatric syndromes and medications and, thus, when deprescribing actions should be initiated by VA care providers. In addition, the clinical care provided during the hospital and SNF stays allows the effects of medication changes to be more closely monitored for safety relative to when the Veteran is at home. Project Objectives: The proposed randomized, controlled trial will evaluate the effects of procedures to reduce medications (DROP) among hospitalized older Veterans discharged to nursing homes using an hybrid study design to inform future efforts to spread it across VA. Project Background/Rationale: Patients discharged to nursing homes for short stays represent the largest group of Medicare beneficiaries discharged to post-hospital services and are a particularly high risk group for loss of independence and other poor clinical outcomes. This investigative team recently completed a VA-funded Quality Improvement Award and a Centers for Medicare and Medicaid Services (CMS) Innovation Award, both of which provide strong results related to the occurrence of polypharmacy and the relationship between polypharmacy and geriatric syndromes (e.g., medications associated with falls) in this patient population. Based on these data, the investigators developed and pilot-tested a patient-centered deprescribing set of procedures combined with standardized questions for eight geriatric syndromes to be implemented in the hospital and monitored during the nursing home stay. Project Methods: The investigators propose an innovative hybrid study design that will be conducted in one VA hospital. The goal of the proposed DROP intervention is to safely deprescribe medications, as defined by reducing doses or stopping medications, based on a combination of clinical criteria and Veteran preferences. This randomized, controlled trial conducted over three years will evaluate the effects of this hospital-based intervention on medication use, geriatric syndromes, and health status across Veterans' care transitions from the hospital to nursing home to home to include a 90-day follow-up period after leaving the nursing home. The hypothesis is that reducing medications for older Veterans will favorably impact geriatric syndromes. Additionally, the investigators aim to understand Veteran, both VA and non-VA provider and system-level factors that help or hinder how well the deprescribing procedures are implemented to inform future clinical uptake and dissemination throughout the VA.

Clinical Trial Description

Note: We have resumed face to face enrollment for non-COVID patients as of 8/17/20. COVID+ patients are being approached by phone. Overview and Specific Aims Polypharmacy, defined as five or more medications, is common in older patients discharged to skilled nursing facilities (SNFs) and is associated with adverse health outcomes. As part of a recent VA project, the investigators prospectively collected medication data for 134 hospitalized, older Veterans. These data showed that, on average, 14.2 medications were ordered for Veterans discharged to SNF, which included 2.5 medications newly prescribed in the hospital that met criteria for being potentially inappropriate medications (PIMs). Moreover, 75% of these Veterans had two or more geriatric syndromes. Geriatric syndromes are clinical conditions common in older adults such as cognitive impairment, unintentional weight loss and falls. The co-occurrence of multiple syndromes is associated with loss of independence and higher healthcare utilization.8 All Veterans with polypharmacy also had one or more medications associated with geriatric syndromes. The prevalence of polypharmacy and multiple geriatric syndromes may partially explain why these patients often have poor health outcomes after SNF discharge. Recent data suggests that only 28% of patients discharged from SNF are living at home 100 days later, and 35% experience an adverse drug event. There is a dearth of evidence related to the management of multiple co-existing geriatric syndromes, and few interventions have been implemented to reduce medications while also monitoring health outcomes. The relationship between polypharmacy, adverse drug events and geriatric syndromes in the VA population supports the rationale for an intervention focused on deprescribing medications before hospital discharge. The investigators have pilot-tested a multifaceted intervention (Drug Reduction in Older Patients, DROP) to engage patients and providers to reduce the number and/or dose of medications prior to hospital discharge. The proposed randomized, controlled trial is powered to evaluate the effect of this intervention on a reduction in medications as defined by the total number of prescribed medications, the number of PIMs, anticholinergic and sedative drug burden and the number of medications associated with geriatric syndromes. In addition, the investigators will collect relevant data on the prevalence and severity of geriatric syndromes and other clinical outcomes. The investigators also will use a hybrid research design to evaluate both effectiveness and implementation issues to better inform future adoption and sustainability. Our overarching hypothesis is that a hospital-based intervention to safely reduce the total number of medications represents the most feasible way to impact multiple health-related outcomes among older Veterans. Our Specific Aims reflect the primary outcomes that are the focus of the analyses, although the investigators also will measure secondary outcomes related to VA healthcare utilization and patient safety: Specific Aim 1: Implement a patient-centered deprescribing intervention (DROP) in the hospital to reduce the total number of medications Veterans are prescribed at hospital discharge. Hypothesis 1a: DROP will result in a significant reduction in total medication exposure due to discontinuations and dose reductions at hospital discharge, SNF discharge and 90-days after SNF discharge. Hypothesis 1b: DROP will result in a significant reduction in the number of potentially inappropriate medications (PIMs) at hospital discharge, SNF discharge and 90-days after SNF discharge. Hypothesis 1c: DROP will result in a significant reduction in the anticholinergic and sedative drug burden at hospital discharge, SNF discharge and 90-days after SNF discharge. Hypothesis 1d: DROP will result in significantly fewer medications associated with geriatric syndromes at hospital discharge, SNF discharge and 90-days after SNF discharge. Specific Aim 2: Document the effects of a Veteran-centered deprescribing intervention (DROP) on medication adherence, health status, and geriatric syndromes. Hypothesis 2a: DROP will result in a significant improvement in medication adherence and self-rated health status at 7 and 90 days after SNF discharge. Hypothesis 2b: DROP will result in a lower prevalence and severity of geriatric syndromes at 7 and 90 days after SNF discharge. Specific Aim 3: Evaluate intervention implementation to inform future adoption and sustainability. Aim 3a: Identify patient-level barriers and facilitators of DROP. Aim 3b: Identify VA and Non-VA provider-level barriers and facilitators of DROP. Aim 3c: Identify system-level factors that influence sustainability after hospital discharge. Potential for Impact: The DROP intervention has significant potential to impact the health of older hospitalized Veterans vulnerable to poor health outcomes. During hospitalization and SNF care, older Veterans often acquire new geriatric syndromes and medications, exactly when deprescribing actions should be initiated by care providers in the context of clinical oversight. Lastly, the application of an innovative hybrid research design will allow us to collect critical data related to both intervention effectiveness and implementation to better inform future adoption and sustainability across the VA. Innovation: Our study is advancing science in multiple ways: 1. The proposed study reflects one of the first controlled intervention trials designed to improve post discharge outcomes for the high-risk population of older Veterans transitioning from hospital to SNF to home. Healthcare costs are increasing for this patient population, and they are at high risk for medication-associated complications and newly acquired geriatric syndromes. 2. Although the number of medications is strongly associated with increases in geriatric syndromes, it is unknown whether reducing medications will improve geriatric syndromes. This trial will generate data to evaluate the impact of medication reduction on Veteran health outcomes. 3. To date, there have been no controlled intervention trials focused on reducing the number of medications prescribed for hospitalized patients discharged to SNF, and the proposed intervention is one of the first to explicitly incorporate Veteran preferences into deprescribing efforts, which is consistent with Veteran-centered care initiatives. Moreover, our preliminary data show that incorporating patient preferences in the intervention protocol significantly changes these clinical decisions. 4. The proposed trial will evaluate both clinical effectiveness and implementation to inform the potential for DROP to be adopted into VA clinical practice. Rationale for VA Study: Dr. Simmons was recently awarded an National Institute on Aging (NIA) R01 focused on polypharmacy in hospitalized non-Veterans. The investigators summarize below the primary differences between the two studies and our rationale for the importance of the proposed VA study: The Need for More Evidence: Our NIA study focuses on non-Veterans hospitalized at Vanderbilt University Medical Center (VUMC) and discharged to a select group of SNFs that have partnered with VUMC for post-acute care services. Unfortunately, the scope of the NIA study does not allow us to evaluate the intervention in two separate healthcare systems with two unique patient populations and a larger number of SNFs, to include VA Community Living Centers and VA contract community nursing homes. Uniqueness of the Veteran population: Our preliminary data demonstrates important differences in older hospitalized Veterans and non-Veterans discharged to SNF. Beyond being predominately male, older Veterans in the investigators' prior study had a higher overall prevalence of geriatrics syndromes and were prescribed more medications at hospital discharge than non-Veterans, particularly antidepressants and antipsychotics. Data also suggests that Veterans may be more willing to reduce their medicines; thus, the magnitude of the intervention effects may differ in the VA. Finally, hospitalized Veterans are discharged to a diverse group of SNFs, many of which are located in rural communities. Unlike the investigators' NIA study, which only includes a select group of partner SNFs predominately located in an urban area close to Vanderbilt, the proposed study will follow Veterans from hospital to SNF to home, irrespective of which SNF they utilize. The VA study, therefore, will more closely mimic real-world practice. The innovative application of an effectiveness-implementation hybrid design will further inform unique aspects of the VA healthcare system critical to adoption. Uniqueness of VA healthcare system: The VA healthcare system differs significantly from other hospital systems, to include medication prescribing practices and how patients access and pay for medications. Thus, the investigators do not expect the results of the NIA study at VUMC to be directly translatable into the VA healthcare system. The proposed study also will yield an understanding of Veteran and VA provider attitudes toward deprescribing and other system factors unique to the VA that may influence intervention implementation. ;
