Provider Perspectives on the Feasibility and Utility of Routine Patient-Reported Outcomes Assessment in Heart Failure: A Qualitative Analysis.

Background Patient-reported outcomes (PROs) objectively measure health-related quality of life and provide prognostic information. Advances in technology now allow for rapid, patient-friendly PRO assessment and scoring, yet the adoption of PROs in clinic has been slow. We conducted a multicenter qualitative study of diverse providers to describe the barriers and facilitators of routine PRO use in heart failure clinics. Methods and Results Sixty heart failure providers from 5 institutions participated in 8 focus groups to explore provider perspectives on the use of heart failure-specific and generic PROs in clinical practice. A qualitative editing approach was used to analyze the data, whereby a coding dictionary was iteratively developed and applied using the qualitative software program Altas.ti. Three main themes, supporting and impeding PRO use, emerged: (1) data collection; (2) presentation and interpretation; and (3) utility and value. For each construct, we identified perspectives that highlighted both barriers and facilitators. Providers identified burden, survey fatigue, and language/health literacy barriers as potentially impeding data collection. Optimal workflow, PRO frequency and length, use of PRO translations, and assistance of a patient's proxy were suggested as facilitators. Focus group discussions provided insight on how to display PROs to support its interpretability and sharing. Furthermore, the need to educate providers on the utility and value PROs over and above current clinical approaches emerged. Conclusions Overcoming the barriers and supporting facilitators of PRO adoption could potentially lead to more successful adoption of PROs in heart failure clinics.

Risk score-guided multidisciplinary team-based Care for Heart Failure Inpatients is associated with lower 30-day readmission and lower 30-day mortality.

OBJECTIVE: Using augmented intelligence clinical decision tools and a risk score-guided multidisciplinary team-based care process (MTCP), this study evaluated the MTCP for heart failure (HF) patients' 30-day readmission and 30-day mortality across 20 Intermountain Healthcare hospitals. BACKGROUND: HF inpatient care and 30-day post-discharge management require quality improvement to impact patient health, optimize utilization, and avoid readmissions. METHODS: HF inpatients (N = 6182) were studied from January 2013 to November 2016. In February 2014, patients began receiving care via the MTCP based on a phased implementation in which the 8 largest Intermountain hospitals (accounting for 89.8% of HF inpatients) were crossed over sequentially in a stepped manner from control to MTCP over 2.5 years. After implementation, patient risk scores were calculated within 24 hours of admission and delivered electronically to clinicians. High-risk patients received MTCP care (n = 1221), while lower-risk patients received standard HF care (n = 1220). Controls had their readmission and mortality scores calculated retrospectively (high risk: n = 1791; lower risk: n = 1950). RESULTS: High-risk MTCP recipients had 21% lower 30-day readmission compared to high-risk controls (adjusted P = .013, HR = 0.79, CI = 0.66, 0.95) and 52% lower 30-day mortality (adjusted P < .001, HR = 0.48, CI = 0.33, 0.69). Lower-risk patients did not experience increased readmission (adjusted HR = 0.88, P = .19) or mortality (adjusted HR = 0.88, P = .61). Some utilization was higher, such as prescription of home health, for MTCP recipients, with no changes in length of stay or overall costs. CONCLUSIONS: A risk score-guided MTCP was associated with lower 30-day readmission and 30-day mortality in high-risk HF inpatients. Further evaluation of this clinical management approach is required.

Implementation of Real-Time Assessment of Patient-Reported Outcomes in a Heart Failure Clinic: A Feasibility Study.

BACKGROUND: Patient-reported outcomes (PROs) quantify, from patients' perspectives, their symptoms, function, and quality of life. Our aim was to determine the feasibility of integrating PRO capture into routine clinical practice at a large heart failure (HF) clinic. METHODS: We examined the practicality of PRO completion at the time of clinic visit, the time required to complete the selected instruments, the completion rate, and the feasibility of immediate PRO scoring and integration of the results into the electronic health record (EHR). We deployed a computer program to capture PROs (Kansas City Cardiomyopathy Questionnaire, Patient-Reported Outcomes Measurement Information System) on a portable computer platform at the time of a clinic visit. An automated algorithm identified patients scheduled for appointments at the HF clinic at registration, provided a portable tablet computer with which to complete the appropriate PRO instruments and then scored and immediately integrated the results in the patient's EHR. RESULTS: In a 12-month period, 862 unique patients completed 1,320 PRO assessments. The mean age of this cohort was 60.1 ± 16.3 years and 66% were male. The average time for PRO assessment was 6.7 minutes and the completion rate among eligible patients was 58%, with 91% of started assessments completed in full. CONCLUSIONS: These preliminary data support the feasibility of serial PRO assessment with real-time integration into the EHR in a large outpatient population of patients with HF. We identified critical steps that should enhance adoption of this approach by clinicians and render PRO results meaningful and actionable in routine clinical care.

Characterization of diffuse fibrosis in the failing human heart via diffusion tensor imaging and quantitative histological validation.

Non-invasive imaging techniques are highly desirable as an alternative to conventional biopsy for the characterization of the remodeling of tissues associated with disease progression, including end-stage heart failure. Cardiac diffusion tensor imaging (DTI) has become an established method for the characterization of myocardial microstructure. However, the relationships between diffuse myocardial fibrosis, which is a key biomarker for staging and treatment planning of the failing heart, and measured DTI parameters have yet to be investigated systematically. In this study, DTI was performed on left ventricular specimens collected from patients with chronic end-stage heart failure as a result of idiopathic dilated cardiomyopathy (n = 14) and from normal donors (n = 5). Scalar DTI parameters, including fractional anisotropy (FA) and mean (MD), primary (D1 ), secondary (D2 ) and tertiary (D3 ) diffusivities, were correlated with collagen content measured by digital microscopy. Compared with hearts from normal subjects, the FA in failing hearts decreased by 22%, whereas the MD, D2 and D3 increased by 12%, 14% and 24%, respectively (P < 0.01). No significant change was detected for D1 between the two groups. Furthermore, significant correlation was observed between the DTI scalar indices and quantitative histological measurements of collagen (i.e. fibrosis). Pearson's correlation coefficients (r) between collagen content and FA, MD, D2 and D3 were -0.51, 0.59, 0.56 and 0.62 (P < 0.05), respectively. The correlation between D1 and collagen content was not significant (r = 0.46, P = 0.05). Computational modeling analysis indicated that the behaviors of the DTI parameters as a function of the degree of fibrosis were well explained by compartmental exchange between myocardial and collagenous tissues. Combined, these findings suggest that scalar DTI parameters can be used as metrics for the non-invasive assessment of diffuse fibrosis in failing hearts.

Effects of the 2006 U.S. thoracic organ allocation change: analysis of local impact on organ procurement and heart transplantation.

BACKGROUND: The United Network for Organ Sharing (UNOS) implemented a thoracic organ allocation policy change (APC) in July 2006 that aimed to reduce death on the waiting list by expanding regional organ sharing. As such, organs would be allocated to the sickest recipients with highest listing status across the region. Our aim was to determine the impact of the new policy on the procurement and transplant process within our program. METHODS: We analyzed data supplied by UNOS as the contractor for the Organ Procurement and Transplantation Network and from the local organ procurement organization for 2 years before and 2 years after implementation of the APC. RESULTS: The APC resulted in an increase in the proportion of Status 1A patients transplanted (24% to 43%, p = 0.015) and a decrease in the proportion of Status 2 patients transplanted (56% to 24%, p = 0.001). Significant increases were observed in mean graft ischemic time (196 minutes to 223 minutes, p = 0.022), number of patients transplanted with ventricular assist devices (17% to 31%, p = 0.036), and procurement costs. There was no significant difference in waiting-list mortality (6% to 5%, p = 0.75) and short-term post-transplant survival. CONCLUSIONS: The 2006 change in UNOS organ allocation policy resulted in an increase in Status 1A transplants, graft ischemic time and procurement costs, and a decrease in Status 2 transplants, but no effect on mortality on the waiting list within our center. To assess the full effect of the APC on outcomes, the long-term impact of the increased graft ischemic time on survival should be quantified.
