Abstract
BACKGROUND: Heart transplantation (HTX) is a well-established treatment for suitable patients with end-stage heart failure, intended to prolong their survival and improve their health-related quality of life (HR-QoL). No international consensus exists, however, about the preferred patient-reported outcomes (PROs) and their measures (PROMs) for heart transplant recipients. The purpose of this study, the first step in a mixed-method investigation, was to review the PROMs developed and used in this population to identify the instruments for measuring HR-QoL and adherence to immunosuppressive medications most appropriate for heart transplant patients. METHODS: This systematic search of the literature in the PubMed database focused on the assessment of PROMs for patients after HTX. We analyzed 66 studies with cross-sectional, 28 with longitudinal, and 2 with mixed-methods designs, as well as 6 literature reviews. RESULTS: These 102 articles used 115 different PROMs, which we categorized as generic HR-QoL instruments (n = 19), domain-specific instruments (n = 71), heart disease-specific instruments (n = 9), and heart transplant-specific instruments (n = 16). They cover different dimensions of HR-QoL and of immunosuppressive-drug experience, with diverse numbers of items, types of scales, and psychometric properties. CONCLUSIONS: Despite the abundance of instruments, PROMs for HTX can be improved to meet other patient expectations (i.e., by including important issues such as coping strategies, employment, social support, sexual relationships, spirituality, and beliefs), while paying attention to ease of use, reliability, validity, and the contribution of new technologies. A qualitative approach will complete our project of developing a patient-centered instrument for HTX patients.
