Importance

The integration of patient-reported outcome (PRO) assessments in cardiovascular care has encountered considerable obstacles despite their established clinical relevance.

Objective

To assess the impact of a physician- and patient-friendly electronic PRO (ePRO) monitoring system on the quality of cardiovascular care in clinical practice.

Design, Setting, and Participants

This open-label, multicenter, pilot randomized clinical trial was phase 2 of a multiphase study that was conducted from October 2022 to October 2023 and focused on the implementation and evaluation of an ePRO monitoring system in outpatient clinics in Japan. During phase 1 (conducted from December 2021 to March 2022), this ePRO monitoring system was developed at a single outpatient center using feedback from patients and physicians. Eligible patients were older than 18 years with a clinical diagnosis of heart failure (HF), atrial fibrillation (AF), or coronary artery disease (CAD). Participants were randomly assigned 1:1 to either the ePRO or control group. Statistical analysis was based on the intention-to-treat approach.

Intervention

Patients in the ePRO group were asked to complete the 12-item Kansas City Cardiomyopathy Questionnaire (KCCQ-12), Atrial Fibrillation Effect on Quality-of-Life Questionnaire (AFEQT), or Seattle Angina Questionnaire (SAQ) on smart tablets before their clinical examination. Results were reviewed by physicians at each outpatient visit. The control group received usual care consisting of medication management, lifestyle modification, and invasive procedures in accordance with clinical guidelines. Both groups had 5 monthly outpatient visits.

Main Outcomes and Measures

Patient satisfaction, quality of information (QOI) provided by physicians, and disease knowledge were assessed using questionnaires (eg, Patient Satisfaction Questionnaire [PSQ]; score range: 5-25, with higher scores indicating greater patient satisfaction) at baseline and the fifth visit, over approximately 4 months.

Results

Of the 50 patients included, 48 (median [SD] age, 71.0 [62.3-75.0] years; 28 males [58.3%]) completed follow-up. The prevalence was 56.2% (n = 27) for HF, 75.0% (n = 36) for AF, and 10.4% (n = 5) for CAD. The distribution of PRO measures used was 21 patients (43.8%) for KCCQ-12, 24 (50.0%) for AFEQT, and 3 (6.2%) for SAQ. Compared with the control group, the ePRO group showed significant improvements in mean (SD) PSQ score (0.16 [2.06] vs 1.61 [1.75]; P = .01) and QOI score regarding treatment (−0.12 [0.53] vs 0.35 [0.71]; P = .01). The ePRO group exhibited a greater increase in the PSQ score regarding communication (−0.12 [0.53] vs 0.43 [0.90]; P = .01).

Conclusions and Relevance

In this randomized clinical trial, implementation of the ePRO monitoring system significantly enhanced patient-physician communication and the clarity of physicians’ explanations about treatment. These findings suggest that the ePRO monitoring system is capable of supporting patient-centered cardiovascular care.
