Abstract

Introduction The decision to reconsider antithrombotic therapy (ATT) in cancer patients nearing the end of life is complex given the increasing risk of haemorrhage and thrombosis. A decision support tool (DST) is being developed to facilitate this process. Understanding patients' experiences, values, and perspectives are an essential component, yet remain largely unexplored. Aim To explore these patients' experiences, values and perspectives regarding ATT use. Methods Qualitative study using semi-structured interviews with patients with advanced cancer receiving ATT, across Denmark, France, Spain, and the United Kingdom. Data were analysed using Framework Analysis. Results Sixty patients and 13 relatives participated. Three major themes were generated: 1. ATT is important and lifelong: Deprescription was perceived as counterintuitive; continuation was preferred, providing a sense of security. 2. Varying perspectives regarding roles and responsibilities in ATT decision-making: Patients' views regarding their role varied. When a good relationship existed with their clinician, patients trusted them to lead on the decision. Relatives played a key supportive role. 3. Challenges in navigating ATT management in the context of advanced cancer and multiple comorbidities: Decisions relating to ATT were rarely made in isolation. Patients prioritised cancer management and described difficulties navigating multiple health concerns. Conclusion Patients found decision-making around ATT near the end of life multifaceted, occurring amid a myriad of competing priorities. While patients reported a reticence to discontinuing, ultimately many deferred such decisions to a clinician, whose role was highly valued. These findings support a need for a DST, to support informed and shared choices in ATT decisions.
