Abstract

W e would like to thank Trujols et al. for their letter and highlighting the importance of using outcomes related to patient perspectives in randomized and longitudinal studies. We agree with the authors that using a multidimensional instrument, instead of the Client Satisfaction Questionnaire 8, will detect more accurate areas of dissatisfaction.Our study, (Optimizing Patient Centered-care: A Pragmatic Randomized Control Trial Comparing Models of Care in the Management of Prescription Opioid Misuse), was a large multicenter pragmatic randomized controlled trial that involved multiple questionnaires throughout the study duration. 1 When we choose Client Satisfaction Questionnaire 8, we opted to use a brief and easy to complete, psychometrically strong measure of treatment satisfaction but did not want to increase study burden by using a more complex measure that contained many more items designed to assess different dimensions of treatment satisfaction. However, we agree and acknowledge the importance of using longer, multidimensional, patient-centered, patientreported experience assessments of this construct in future longitudinal studies in patients receiving opioid agonist therapies. Therefore, we conducted an ancillary nested qualitative study 2 to gain an indepth understanding of the multidimensional perspectives of participants, as well as clinicians, regarding the interventions and their participation in the (Optimizing Patient Centered-care: A Pragmatic Randomized Control Trial Comparing Models of Care in the Management of Prescription Opioid Misuse) study. We hoped that such a qualitative approach would provide complementary and richer data pertaining to participants' perspectives on opioid agonist therapies, which hopefully might contribute to future development of relevant measure.
