Perspective on oral medication adherence among patients with acute graft-versus-host disease: a qualitative descriptive study

Abstract

Purpose Despite the importance of adherence to immunosuppressants (IMMs) after an allogeneic haematopoietic stem cell transplant (HSCT) for the treatment of acute graft-versus-host disease (aGvHD), no studies to date have reported the experiences of such patients concerning medication adherence (MA). Therefore, the aim of the study was to explore the perspective on MA to immunosuppressive oral therapy among allogeneic HSCT patients with aGvHD. Methods A qualitative descriptive study following a reflexive thematic analysis methodological approach was performed involving a purposive sample of 16 patients with aGvHD who were being cared for in the outpatient setting of a bone marrow transplant centre and were willing to participate. Semi-structured audio-recorded interviews were conducted, transcribed verbatim and thematically analysed; member checking was performed. COnsolidated criteria for REporting Qualitative research (COREQ) and the ESPACOMP Medication Adherence Reporting Guideline were followed. Results Participants aged 25–74 years and mostly males (62.5%) were recruited for this study; 56.2% developed grade I, 37.5% grade II and 6.3% grade III aGvHD; 56.2% were receiving treatment with both cyclosporine and prednisone. Patients' perspectives have been summarised into four themes, named: “Transiting from an external obligation to a habit”; “Being in the middle between the negative and positive effects of the IMMs”; “Failure to systematically respect the rules”; and “Adopting personal strategies to become adherent”. After difficulties with the perception of feeling obliged, patients became used to adhering to IMMs. Although there were failures in systematically taking the medication correctly and there were episodes of non-adherence, the adoption of personal strategies helped patients to become adherent to their medication schedules. Conclusions MA in patients with aGvHD is a complex behaviour and is often a challenge. These results can help healthcare professionals and centres to understand how best to design tailored strategies and behavioural interventions to maximise patients’ MA to IMMs.
