OBJECTIVES: To test if Patient Reported Outcomes (PRO) data can replace physical on-site consultation in determining if patients with multiple myeloma, AL amyloidosis, or plasma cell leukemia are ready for their next bortezomib treatment without dose reduction.
METHODS: We developed an online questionnaire addressing common side effects to bortezomib and an algorithm stratifying patients according to their responses and asked them to complete the questionnaire the day before attending the clinic. Applying a mixed-method study design of PRO data, time registrations, and interviews with patients and healthcare professionals, we tested the usability of electronic PRO data forming the basis of decision-making on whether patients are physically fit for the next treatment with an unchanged dose.
RESULTS: The questionnaire and the associated algorithm were able to identify patients who were physically fit for treatment without need for further consultation, with a positive predictive value of 98 %. The method proved to be feasible for all groups of patients regardless of age and educational level. Patients and healthcare professionals found the online questionnaire to be advantageous and flexible.
CONCLUSION: The use of PRO data to evaluate patients prior to bortezomib treatment is safe and feasible. Patients prefer to report their side effects themselves as it provides them with more freedom during their treatment.
