MMpowerment: Empowering patients with multiple myeloma for shared decision-making by developing an intervention to integrate personal preferences into digital care pathways.

OBJECTIVE: As part of a quality improvement initiative in the context of value-based health care we aimed to optimize the shared decision-making (SDM) process in the care pathway for Multiple Myeloma as part of a digital care pathway (DCP). For this, more insight was needed in health care professionals' (HCPs') perspectives on SDM, and how SDM elements could be addressed in a DCP for MM to facilitate HCPs' performance of SDM. METHODS: HCPs were interviewed as per the theory of planned behaviour and the model of organizational context and SDM (phase 1). Multidisciplinary development sessions were organized to discuss concepts of the solution with HCPs (phase 2). The solution was evaluated with two patients from the quality improvement team. RESULTS: In phase 1, ten interviews were held. HCPs' attitudes and the subjective norm towards SDM were positive, and the intention to perform SDM was high. The clinical environment (physical context, disease characteristics, assumptions about patient characteristics, and workflows) for MM posed challenges on the actual SDM behavior. Education and use of the DCP to create awareness of SDM were seen as possible facilitators for SDM. A prepared and active patient would facilitate the SDM process. In phase 2, three concept solutions were developed before arriving at the final solution. The final solution consisted of three elements to incorporate SDM steps in the DCP: 1) creating patient awareness and activation with two questions about their preferences prior to a consultation, 2) visualisation of preferences centrally in the DCP to trigger HCP to discuss them, 3) monitoring and improving SDM with patient-questionnaires after decision-making. Patients and HCPs were willing to implement it. CONCLUSION: HCPs intention to engage in SDM was high, but their actual behaviour was challenged by the clinical environment. A 3-element DCP-based intervention was developed to increase SDM. PATIENT OR PUBLIC CONTRIBUTION: Input on the solution was obtained from end-users including two patients and ten healthcare professionals.

Benefits and risks of clofarabine in adult acute lymphoblastic leukemia investigated in depth by multi-state modeling.

BACKGROUND: We recently reported results of the prospective, open-label HOVON-100 trial in 334 adult patients with acute lymphoblastic leukemia (ALL) randomized to first-line treatment with or without clofarabine (CLO). No improvement of event-free survival (EFS) was observed, while a higher proportion of patients receiving CLO obtained minimal residual disease (MRD) negativity. AIM: In order to investigate the effects of CLO in more depth, two multi-state models were developed to identify why CLO did not show a long-term survival benefit despite more MRD-negativity. METHODS: The first model evaluated the effect of CLO on going off-protocol (not due to refractory disease/relapse, completion or death) as a proxy of severe treatment-related toxicity, while the second model evaluated the effect of CLO on obtaining MRD negativity. The subsequent impact of these intermediate events on death or relapsed/refractory disease was assessed in both models. RESULTS: Overall, patients receiving CLO went off-protocol more frequently than control patients (35/168 [21%] vs. 18/166 [11%], p = 0.019; HR 2.00 [1.13-3.52], p = 0.02), especially during maintenance (13/44 [30%] vs. 6/56 [11%]; HR 2.85 [95%CI 1.08-7.50], p = 0.035). Going off-protocol was, however, not associated with more relapse or death. Patients in the CLO arm showed a trend towards an increased rate of MRD-negativity compared with control patients (HR MRD-negativity: 1.35 [0.95-1.91], p = 0.10), which did not translate into a significant survival benefit. CONCLUSION: We conclude that the intermediate states, i.e., going off-protocol and MRD-negativity, were affected by adding CLO, but these transitions were not associated with subsequent survival estimates, suggesting relatively modest antileukemic activity in ALL.
