Trial Summary

What is the purpose of this trial?

The goal of this pragmatic cluster randomized clinical trial is to compare management of suspected infection in nursing home residents with dementia The main questions it aims to answer whether residents with dementia in nursing homes randomized to use a multicomponent intervention to optimize suspected infection management ( versus usual care) use less antibiotics and fewer burdensome interventions.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It is best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the treatment TRAIN AD 2.0 for reducing antibiotic use in dementia patients?

The TRAIN-AD intervention, which is similar to TRAIN AD 2.0, was a program aimed at improving infection management in nursing home residents with advanced dementia, suggesting that structured programs can help reduce unnecessary antibiotic use in this population. ^{1 2 3 4 5}

Is the treatment in the clinical trial generally safe for humans?

The research highlights that people with dementia are at risk of adverse drug reactions (ADRs), but it does not provide specific safety data for the treatment in the clinical trial. ^{6 7 8 9 10}

How is the TRAIN AD 2.0 treatment different from other treatments for reducing antibiotic use in dementia patients?

TRAIN AD 2.0 is unique because it is a multicomponent program designed to improve infection management specifically for nursing home residents with advanced dementia, focusing on reducing unnecessary antibiotic use by considering the goals of care and evidence of infection. ^{3 4 11 12 13}

Findings from Research

This study will evaluate the effectiveness of a clinician champion intervention over 24 months to reduce the use of potentially inappropriate medications (PIMs) in people living with dementia, aiming to improve medication safety.

The trial will also assess whether this intervention leads to fewer emergency department visits and hospitalizations due to falls, using Medicare claims data to track outcomes in two participating accountable care organizations.

Can clinician champions reduce potentially inappropriate medications in people living with dementia? Study protocol for a cluster randomized trial. Parchman, ML., Perloff, J., Ritter, G.[2022]

Upon admission to nursing homes, 40.1% of residents with dementia were prescribed cholinesterase inhibitors (ChEIs) and memantine, with higher usage in those with mild to moderately severe dementia compared to those with advanced dementia.

After 3 months, the use of ChEIs and memantine decreased significantly, with residents having advanced dementia being 1.44 times more likely to reduce their medication compared to those with less severe dementia, highlighting a need for further research on medication optimization in this population.

The TRAIN-AD trial successfully achieved high participation rates in training activities among nursing home providers, with 93% of the 380 participants attending at least one training session.

Factors such as being a nurse, working in higher quality facilities, and being present at the start of the program were associated with greater adherence to the training components, indicating areas for improvement in future training efforts.

In a study of 430 nursing home residents with advanced dementia, 13.7% received antimicrobials in the two months prior to the study, highlighting a significant issue of antimicrobial use in this vulnerable population.

Facility characteristics, such as having a full-time nurse practitioner or physician assistant and fewer established infectious disease practices, were linked to higher rates of antimicrobial prescriptions, suggesting that improving these practices could help reduce unnecessary antimicrobial use.

The prevalence of dementia among veterans aged 65 and older was found to be 4.8% using only Veterans Health Administration (VHA) data, but increased to 7.4% when combined with Medicare data, highlighting the importance of comprehensive data sharing.

The average annual cost attributable to dementia was estimated at $10,950 per veteran using VHA data alone, but this figure dropped to $6,662 when considering combined VHA and Medicare data, suggesting that integrated data can provide a more accurate picture of healthcare costs.

In a study of 1332 patients with Alzheimer's disease or other dementias in France, the prevalence of adverse drug reactions (ADRs) was found to be 5.0%, with serious ADRs occurring in 31.9% of cases, highlighting the potential risks associated with medication in this population.

The most common ADRs were gastrointestinal, central nervous system, and psychiatric disorders, with anti-dementia and psychotropic drugs being the most frequently implicated, indicating a need for careful monitoring and prescribing practices in patients with dementia.

A systematic review of 26 studies found that the prevalence of potentially inappropriate prescribing in older people with dementia ranges from 14% to 74%, highlighting a significant risk for adverse events in this population.

The Beers criteria were the most commonly used tool for identifying inappropriate prescriptions, but many studies did not utilize the full criteria, suggesting a need for more standardized and comprehensive application of these tools.

A systematic review of 5 studies found that the prevalence of adverse drug events (ADEs) in older inpatients with dementia is alarmingly high at 81.5%, indicating a significant safety concern for this population.

The prevalence of adverse drug reactions (ADRs) varied between 12.7% and 24.0%, highlighting the need for better assessment methods and tailored tools to prevent these reactions in older patients with dementia.

The introduction of the West Wales ADR Profile for Mental Health Medicines significantly increased the number of clinical problems addressed in dementia patients, from an average of 6.02 to 9.86, indicating improved monitoring and care.

Using the ADR Profile led to a reduction in the prescribing of mental health medications, suggesting it can enhance the safety and quality of care for individuals with dementia.

Acute renal failure was identified as the most common adverse drug reaction (ADR) in dementia patients, leading to longer hospital stays (median of 9 days for ADR-related admissions compared to 6 days for non-ADR admissions).

Patients with dementia who experienced ADRs had significantly higher in-hospital mortality and increased risk of subsequent ADR-related admissions within 30, 60, and 90 days, highlighting the need for careful medication management and monitoring.

A study of 3,913 E. coli and 1,736 K. pneumoniae urine isolates from home-based primary care patients with dementia revealed high annual rates of antimicrobial resistance between 2014 and 2018, with ciprofloxacin resistance at 18%-23% for E. coli and 5%-7% for K. pneumoniae.

Multidrug resistance was also significant, affecting 9%-11% of E. coli and 5%-6% of K. pneumoniae isolates, indicating a need for further research on antimicrobial resistance in home-care settings.

In a study of 240 elderly patients with advanced dementia, 64% experienced suspected pneumonia episodes in their last six months, highlighting pneumonia as a common terminal condition in this population.

The aggressiveness of antibiotic treatment for pneumonia was influenced by factors such as the presence of a do-not-hospitalize order, aspiration events, the patient's primary language, and unstable vital signs, indicating the importance of advance care planning and clinical assessment in treatment decisions.

A multicomponent intervention aimed at improving the management of suspected urinary tract infections (UTIs) and lower respiratory infections (LRIs) in nursing home residents with advanced dementia did not significantly reduce the overall use of antimicrobials, despite high adherence to training among healthcare practitioners.

However, the intervention did lead to a significant reduction in the use of chest radiography for diagnosing LRIs, indicating some positive impact on the management of these infections.
