A Structured Peer Support Intervention for Patients With Hematologic Malignancies Undergoing Hematopoietic Stem Cell Transplantation: Peer Support Interventionists' Perspectives

Abstract

Background: Peer support is emerging as an important component of supportive care for patients with hematologic malignancies, but it has not been robustly implemented in patients undergoing hematopoietic stem cell transplantation (HSCT).

Objectives: This qualitative study aimed to explore the experiences of peer support interventionists (participants) delivering a structured, 5-session, phone-delivered peer support intervention, the Supporting Transplant Experiences with Peer Program (STEPP) for patients undergoing HSCT.

Methods: Adult patients who underwent allogeneic or autologous HSCT for the treatment of a hematologic malignancy within the past 3 years were eligible to volunteer in this study as trained STEPP interventionists. Semi-structured qualitative interviews were conducted to explore participants' experiences, including their motivations for volunteering, reflections on intervention delivery and on the impact of peer support, and challenges faced while serving in this role. Interviews were deductively analyzed by 2 coders using framework-guided rapid analysis.

Results: Twenty STEPP interventionists participated in this study. Participants were 65% men, with a median age of 63.5 years. Most (75%) had undergone allogeneic HSCT. Emerging themes from the qualitative interviews highlighted that participants were motivated to serve as interventionists by a sense of gratitude for their transplant care and a desire to share their transplant experiences with others. The impact of the STEPP intervention on interventionists included opportunities to process their transplant journey while also providing support to their peers. Interventionists reported a preference for free-flowing conversations, which were still guided by the structured manual. Challenges included terminating the interventionist-patient relationship at the conclusion of STEPP.

Conclusion: Peer support interventions for patients undergoing HSCT have the potential to enhance well-being and provide meaning for both patients preparing to undergo HSCT and HSCT survivors who serve as interventionists. Large-scale randomized clinical trials are needed to test the efficacy of peer support interventions for improving health-related outcomes among patients undergoing HSCT and HSCT survivors serving as interventionists for these interventions.
