Clinical Trial Summary

Recent institutional research has demonstrated that black and Latinx patients are significantly less likely to be admitted to cardiology and more likely to be admitted to general medicine for their inpatient heart failure (HF) care. Subsequent HF care on general medicine has been demonstrated to have worse outcomes including lower rates of follow-up with cardiology and higher readmission rates. Given this, this project is a institutional quality improvement initiative, with a stepped wedge design, with the aim to improve the quality of care for heart failure patients admitted to general medicine for their care, and improve discharge planning. General medicine services by hospital pods will be enrolled in a stepped wedge fashion to a Longitudinal Equity Action Plan (LEAP) which includes a standardized clinical management plan to ensure patients are on guideline-appropriate therapy, receive cardiology consultation if appropriate, are discharged when clinically appropriate, discharge planning and systematic follow up with cardiology, transportation support as needed for follow-up visits, post-discharge follow up to identify any post-discharge issues.


Clinical Trial Description

I. Aims with respect to Health Equity in the Department of Medicine

AIM 1: To improve the quality of care for heart failure patients admitted to the General Medicine Service (GMS) Aim 1a. To increase adherence and uptake of guideline-directed medical therapy and appropriate post-discharge follow-up for patients with heart failure admitted to GMS Aim 1b. To decrease 7-day heart failure readmission rates for patients with heart failure admitted to GMS with a principal diagnosis of heart failure Aim 1c. To decrease 30-day heart failure readmission rates for patients with heart failure admitted to GMS with a principal diagnosis of heart failure

AIM 2: To improve post-discharge outpatient cardiology utilization for heart failure patients admitted to GMS Aim 2a. To increase rates of cardiology clinic follow-up within 14 days of discharge for patients admitted to GMS with a principal diagnosis of heart failure.

II. Significance & Innovation A recent retrospective analysis performed by the Brigham and Women's Hospital (BWH) Cardiovascular Inequities Subcommittee of the Department of Medicine Health Equity Committee of patients self-referred to the Emergency Department with a principal diagnosis of heart failure found that black and Latinx patients were significantly less likely to be admitted to the cardiology service despite adjustment for multiple medical and socioeconomic factors (adjusted odds ratio [AOR] 0.68, 95% CI 0.53-0.87, for black patients; AOR 0.52, 95% CI 0.34-0.82 for Latinx patients). Female gender (AOR 0.75, 95% CI 0.62-0.91) and age>75 (AOR 0.58, 95% CI 0.40-0.86) were also independently associated with lower rates of admission to the cardiology service.

Similar to large observation studies from both community and academic settings, further analysis by the committee revealed differential outcomes for patients receiving specialty cardiology care during admissions for heart failure with lower cardiology clinic follow-up (25% vs. 51%), and higher 7-day (15% vs 5%) and 30-day (24 vs 17%) readmission rates for heart failure patients admitted to GMS as compared to those admitted to the cardiology service.

Given this result, the investigators hypothesize that inequities in admission service triage of heart failure patients may drive intra-hospital racial disparities in quality of care, and subsequent clinical outcomes. This project's aim is to achieve more equitable care and reduce unacceptable inequities in heart failure management and outcomes. Acknowledging that cardiology beds are a limited resource, and that not every patient can be admitted to the cardiology service at the investigators' institution, this project seeks to improve the quality of care for heart failure patients admitted to GMS. The investigators believe that improving the quality of heart failure care on GMS, including more systematic cardiology follow up, will lower heart failure readmission rates for the investigators' institution. Furthermore, this project will likely also lead to more equitable admission patterns downstream and will increase future admission to the cardiology service when appropriate because of the significant influence of cardiology outpatient follow up on admission to the cardiology service (adjusted OR of 2.31 [1.87, 2.84]).

III. Implementation Plan

Study design:

The investigators will implement a stepped-wedge design to expand to GMS a model of standardized clinical assessment and management (SCAMP) for heart failure. To assess the effectiveness of the intervention, measurement of cardiology clinic follow-up within 14 days of discharge, as well as 7-day and 30-day readmission rates for patients with heart failure admitted to GMS will be performed at baseline, at each cross-over time point, and at the conclusion of the intervention.

Methods:

Previous studies have demonstrated that SCAMPs lead to improved outcomes and promote the delivery of high-quality, cost-effective care. The SCAMP proposed, which is currently utilized for patients admitted to the BWH cardiology service, incorporates components of the American Heart Association's "Get with the Guidelines," to ensure patients are on guideline-directed medical therapy. The SCAMP as implemented on GMS will be titled the Longitudinal Equity Action Plan (LEAP), and will include support services to ensure 1) heart failure medications are covered and affordable 2) systematic scheduling of follow-up cardiology clinic appointments, and 3) barriers to patient attendance of cardiology appointments are addressed (e.g. through provision of ride vouchers). A LEAP program assistant will be responsible for completing the web-based LEAP form for each heart failure patient admitted to GMS. These forms are designed to ensure that patients are on guideline-directed medical therapy, with discussions with the primary medical team to understand rationale if medical therapy is not optimized, and that patients are scheduled with cardiologist follow-up appointment within 14 days of discharge. The LEAP program assistant will provide heart failure education to each patient including importance of weighing themselves daily, fluid and salt restriction, and in collaboration with the primary team, a "rescue plan" will be made for each patient in case they gain weight before their follow-up appointment. The LEAP program assistant will also be responsible for calling each patient's pharmacy to ensure medications are covered by insurance prior to discharge. Transportation assistance will be provided for all heart failure patients admitted to GMS to use for transportation to cardiology follow-up appointments..

The investigators will implement the LEAP within the investigators' institution's eight GMS teams. These teams have similar team structures, including a hospitalist attending and medical residents or physician assistants. The implementation of the medicine service will be introduced over a one-year period following a stepped wedge design. At four sequential time points, two GMS teams (clusters) will be randomized to cross from the usual care period to the intervention period. The process will continue until all clusters have crossed over to be exposed to the intervention (the LEAP). The intervention implementation process will include intensive training of hospital attendings, medical residents, and physician assistants in utilization of the LEAP.

Analysis:

The primary outcome of interest measured will be rates of cardiology clinic follow-up within 14 days. Second outcomes will include cardiology clinic follow-up within 30 days of discharge, 7-day readmission rates, and 30- day readmission rates. Other outcomes will include rates of cardiology consultation and rates of transportation support. The main analysis of the stepped wedge design will be based on a logistic mixed-effects model which will contain a random intercept to account for between-cluster variability, a fixed effect parameter for time, and a group indicator variable for the treatment for each subject and time to capture treatment differences over time. Assuming there are 20 patients per cluster, four time-points with one baseline measurement, and eight clusters, the investigators will have 98% power to detect a change in proportion of patients with 14-day cardiology follow-up from 25% to 50%, with Type I error rate of 5%.

IV. Future Directions and Amplification of Impact The investigators believe that improving heart failure care on GMS will lead to more equitable care and outcomes for not only black and Latinx patients but for all patients admitted to GMS with heart failure. If implementation of the LEAP on GMS proves to be impactful in improving heart failure outcomes, this may lead to uptake of similar strategies to improve care for other common disease entities, as well as access to specialized outpatient care, which is of paramount importance given that racial differences in referral patterns to outpatient specialty care for black and Latinx patients has been demonstrated. Success of this project may promote similar approaches to be employed by other departments to promote more equitable care of all patients. Furthermore, the investigators believe that this project will provide a platform for health equity capacity building for DOM faculty, opportunities for scholarship, and shared learning on health equity methodology. ;
