Informatics Tools in Deprescribing and Medication Optimization in Older Adults: Development and Dissemination of VIONE Methodology in a High Reliability Organization.

PURPOSE: Polypharmacy is common in older adults, with almost 20% of older adults taking ≥10 medications. They are at great risk for adverse events related to potentially inappropriate medications (PIMs). Although evidence-based methods for deprescribing have been successful at reducing polypharmacy and improving quality of medication use, there are several challenges to implementing these methods on a large scale. VIONE, a medication deprescribing methodology, was developed to reduce polypharmacy and PIMs across the Veterans Health Administration (VHA). (VIONE stands for Vital, Important, Optional, Not indicated, and Every medication has an indication.) This study describes the tools created for implementation of VIONE and the dashboards used to track VIONE implementation and subsequent deprescribing across the VHA; their use and sustainment are examined in a health system-wide adoption of this deprescribing practice in a high reliability organization (HRO). METHODS: VIONE was disseminated by the VHA via the Diffusion of Excellence Initiative. Dissemination included an implementation toolkit and four dashboards that collect and display data from the electronic medical record to monitor utilization of VIONE, track medication discontinuations, and prospectively identify veterans who may be candidates for deprescribing. FINDINGS: Between 2016 and the present, VIONE has been adopted at >130 medical centers and influenced almost 700,000 unique patients. In addition, a total of >1.6 million medication orders have been discontinued by >15,000 providers. IMPLICATIONS: The VIONE methodology and informatics tools were widely disseminated and successfully adopted and sustained nationally in a high reliability organization, leading to a reduction in PIM use by older adults and improved quality and patient safety. Future efforts should continue to consider ways to leverage electronic medical record data and other relevant informatics tools to provide customized clinical decision support to further medication optimization and deprescribing efforts.

Maintaining Implementation through Dynamic Adaptations (MIDAS): protocol for a cluster-randomized trial of implementation strategies to optimize and sustain use of evidence-based practices in Veteran Health Administration (VHA) patients.

BACKGROUND: The adoption and sustainment of evidence-based practices (EBPs) is a challenge within many healthcare systems, especially in settings that have already strived but failed to achieve longer-term goals. The Veterans Affairs (VA) Maintaining Implementation through Dynamic Adaptations (MIDAS) Quality Enhancement Research Initiative (QUERI) program was funded as a series of trials to test multi-component implementation strategies to sustain optimal use of three EBPs: (1) a deprescribing approach intended to reduce potentially inappropriate polypharmacy; (2) appropriate dosing and drug selection of direct oral anticoagulants (DOACs); and (3) use of cognitive behavioral therapy as first-line treatment for insomnia before pharmacologic treatment. We describe the design and methods for a harmonized series of cluster-randomized control trials comparing two implementation strategies. METHODS: For each trial, we will recruit 8-12 clinics (24-36 total). All will have access to relevant clinical data to identify patients who may benefit from the target EBP at that clinic and provider. For each trial, clinics will be randomized to one of two implementation strategies to improve the use of the EBPs: (1) individual-level academic detailing (AD) or (2) AD plus the team-based Learn. Engage. Act. PROCESS: (LEAP) quality improvement (QI) learning program. The primary outcomes will be operationalized across the three trials as a patient-level dichotomous response (yes/no) indicating patients with potentially inappropriate medications (PIMs) among those who may benefit from the EBP. This outcome will be computed using month-by-month administrative data. Primary comparison between the two implementation strategies will be analyzed using generalized estimating equations (GEE) with clinic-level monthly (13 to 36 months) percent of PIMs as the dependent variable. Primary comparative endpoint will be at 18 months post-baseline. Each trial will also be analyzed independently. DISCUSSION: MIDAS QUERI trials will focus on fostering sustained use of EBPs that previously had targeted but incomplete implementation. Our implementation approaches are designed to engage frontline clinicians in a dynamic optimization process that integrates the use of actional clinical data and making incremental changes, designed to be feasible within busy clinical settings.

Understanding Principles of High Reliability Organizations Through the Eyes of VIONE: A Clinical Program to Improve Patient Safety by Deprescribing Potentially Inappropriate Medications and Reducing Polypharmacy.

The assessment of polypharmacy and reduction of potentially inappropriate medications using VIONE has benefited about 60,000 veterans with more than 128,000 medications deprescribed, yielding more than $4 million in annualized cost avoidance.

Novel isomeric metabolite profiles correlate with warfarin metabolism phenotype during maintenance dosing in a pilot study of 29 patients.

: For this pilot study, we leveraged metabolite patterns for warfarin patients to more accurately assess clinically relevant differences in drug metabolism. We tested our hypothesis that plasma metabolite levels correlate with the influence of clinical factors on R-warfarin and S-warfarin metabolism (warfarin metabolic phenotype). We recruited 29 patients receiving a maintenance dose and testing within targeted therapeutic range. We determined their CYP2C9 and vitamin K epoxide reductase genotype and profiled 14 isomeric forms of warfarin and its metabolites. We employed three novel types of clearance ratios using analyte levels to perform multiple-linear regression analyses with clinical factors impacting drug metabolism and dose-responses. Competitive clearance ratios correlated with seven clinical factors including lifestyle choices (smoking), genetics (CYP2C9 and vitamin K epoxide reductase 1), and drug interactions (omeprazole) along with age, weight, and malignancy. Significant competitive clearance ratio correlations (P = 0.04 to < 0.001) explained 21-95% variability. Their performances surpassed that of oxidative and metabolic clearance ratios based on the number and significance of correlations. Competitive clearance ratios may accurately assess significance of factors on maintaining levels of pharmacologically active forms of the drug and metabolites related to dose-responses and thus provide a strategy to minimize adverse events and improve safety during anticoagulant therapy. This unique capacity could provide a strategy in a future, higher power study with a larger cohort of patients to more accurately assess the significance of clinical factors on active drug levels contributing to warfarin dose-responses.

Impact of the Implementation of Project Re-Engineered Discharge for Heart Failure patients at a Veterans Affairs Hospital at the Central Arkansas Veterans Healthcare System.

Background: Hospitalizations due to chronic diseases such as heart failure (HF) continue to increase worldwide. Fragmentation of care while transitioning from one care setting to another is an important factor contributing to hospitalizations. Fragmented discharge tools have been implemented; however, the impact of a comprehensive interdisciplinary discharge tool has not been previously studied. Objective: The goal of this study is to assess the impact of the implementation of Project Re-Engineered Discharge (RED) on the incidence of hospital readmissions, all-cause mortality, primary care physician follow-up rate, and cost savings for patients with HF. Methods: This was a single-center, retrospective, cohort study of patients admitted with HF exacerbation at the Central Arkansas Veterans Healthcare System (CAVHS). A random sample of 100 patients admitted prior to implementation of Project RED and 50 patients after Project RED intervention were included in the study. The primary end point was 30-day hospital readmission for HF exacerbation. The co-secondary end points were all-cause mortality, cost savings, and rate of primary care physician appointments scheduled as well as attended per postdischarge recommendations. Results: The 30-day hospital readmission rate was 28% in the pre-Project RED group, and it was 18% in the post-Project RED group (P = .18). The all-cause mortality was significantly lower in the post-Project RED group as compared with the pre-Project RED group (18% vs 41%, P = .04). More patients in the post-Project RED group attended an outpatient primary care appointment as recommended per postdischarge instructions (40% vs 19%, P = .006). In addition, with the decrease in hospital 30-day readmission rate in the post-Project RED group, there was a cost savings of $1453 per patient visit for HF exacerbation. Conclusions: Coordination of care using a discharge tool like Project RED should be utilized in institutions to improve patient outcomes as well as patient safety while decrease the overall health care cost.

Catch-up growth for the extremely low birth weight infant.

PURPOSE: This retrospective chart review describes the growth of extremely low birth weight (ELBW) infants after discharge from the neonatal intensive care unit. DESIGN: A descriptive design was used to collect data from 60 hospital records. RESULTS: Gains were noted between assessment periods (discharge--6 months and 6-12 months) (t = 4.57, t = 5.60, t = 10.77, p < 0.001) for weight, length, and head circumference, respectively. A negative change in weight (z = -1.9; CI = -3.1, -0.66) within the discharge to 6-month assessment period and a positive change in length (z = 0.54, CI = 0.05, 1.04) within the 6 to 12-month assessment were noted. Each assessment was significantly below the 50th percentile of full-term infants with weight at the 7th percentile at 12 months. DISCUSSION: The ELBW infants showed gains relative to the full-term infant but lagged behind on each growth parameter at each assessment.

"The rock always comes first": drug users' accounts about using formal health care.

Illicit drug use remains a significant public health threat. The issues surrounding drug use are recognized by public health professionals as important for several reasons. The incidence and prevalence of drug use persists in spite of the extensive societal, interpersonal, and individual consequences. In addition, the chronic health issues and health care costs associated with drug use continue to spiral. A wide variety of quantitative studies have examined the extent of health care problems, access, cost, and health care satisfaction among illicit drug users. While these studies offer important information through survey formats, fewer studies focus on subjective constructions of health care management from the users' perspective. This article examines the elements of the decision-making process involved in accessing formal health care among chronic and injecting street drug users. Twenty-eight in-depth interviews provide the data for this analysis, which is part of a large quantitative study of 1,479 injecting and chronic drug users and nondrug users in Miami, Florida. By exploring the elements of health care access through the eyes of the drug users, researchers and treatment professionals may gain insights into new ways to improve health care access for this at-risk population.
