Abstract
Background: Despite the association between peer support interventions and improved patient-reported outcomes (PROs) across cancer populations, there is a lack of structured peer support interventions for patients with hematologic malignancies undergoing hematopoietic stem cell transplantation (HSCT).
Objective: To test the feasibility, acceptability, and preliminary efficacy of a novel five-session, phone-delivered peer support intervention (STEPP: Supporting Transplant Experiences with Peer Program) for improving quality of life (QOL) and reducing psychological distress in patients undergoing HSCT.
Methods: This single-center pilot randomized clinical trial (RCT) will compare the STEPP intervention to usual transplant care among 90 patients hospitalized for HSCT. Eligible participants include adults (age ≥ 18 years) with hematologic malignancies hospitalized for autologous or allogeneic HSCT. The STEPP intervention provides informational, emotional, and practical support. To test the primary aim of intervention feasibility, we have established a priori benchmarks of 60 % enrollment of eligible patients and 60 % completion of at least 3 out of 5 intervention sessions among those randomized to STEPP. Acceptability will be assessed using the Client Satisfaction Questionnaire, with scores ≥3.0/4.0 indicating greater intervention acceptability. To test the secondary aim of preliminary efficacy, we will examine changes in PROs (e.g., anxiety symptoms and QOL) from pre- to post-intervention.
Discussion: This pilot RCT of a structured, phone-delivered peer support intervention tailored to the needs of patients preparing to undergo HSCT will elucidate the feasibility, acceptability, and preliminary efficacy of the STEPP intervention. We will then be poised to conduct a future, full-scale RCT to establish the efficacy of STEPP on patient outcomes.
期刊介绍：
Contemporary Clinical Trials is an international peer reviewed journal that publishes manuscripts pertaining to all aspects of clinical trials, including, but not limited to, design, conduct, analysis, regulation and ethics. Manuscripts submitted should appeal to a readership drawn from disciplines including medicine, biostatistics, epidemiology, computer science, management science, behavioural science, pharmaceutical science, and bioethics. Full-length papers and short communications not exceeding 1,500 words, as well as systemic reviews of clinical trials and methodologies will be published. Perspectives/commentaries on current issues and the impact of clinical trials on the practice of medicine and health policy are also welcome.
