Videographic Analysis of an Intervention to Improve Patient-Centered Care for People Living with Type 2 Diabetes: the QBSAFE Randomized Trial

BackgroundThe self-management of type 2 diabetes (T2D) typically requires enacting various lifestyle changes, which can challenge people living with T2D. Clinical encounters between people with T2D and their clinicians, however, are often focused on metabolic management, leaving less time available for other self-management topics. The QBSAFE cards help patients articulate aspects of their experience with diabetes and prioritize issues for discussion. MethodsThis report details secondary outcomes of a randomized controlled trial; primary outcomes are reported elsewhere. All data was collected at Fair Haven Community Health Care, a federally qualified primary care clinic. 11 clinicians were randomly assigned to provide either usual care or usual care with QBSAFE cards to 155 of their patients with type 2 diabetes and hemoglobin A1c >8%. All patient encounters were video recorded for analysis. Patients and clinicians were not blinded to arm allocation but were kept unaware of the specific aims of the trial. Encounter video reviewers were blinded to arm allocation, but not to specific aims of the trial. The outcomes of interest for this report were the extent to which the QBSAFE cards were used as intended, their effect on the topics of discussion, and whether they enabled clinicians to notice and respond to each patients situation; comparisons between arms were conducted by a linear mixed model with fixed effect of arm and cluster effect of clinician, analyzed in both intent-to-treat and per-protocol populations. Findings12 patients were excluded post-randomization (A1c <8%). Of 143 eligible patients, 137 encounters (65 in the usual care arm, 72 in QBSAFE) yielded evaluable videos. QBSAFE was used as intended in 61 (85%) QBSAFE arm encounters. Conversations about burden of treatment related to non-pharmacological interventions (17 vs 33, p= 0{middle dot}04) and taking medications (11 vs 33, p= 0{middle dot}0008) and about the patients challenging environment (2 vs 10, p= 0{middle dot}04) were more prevalent in the QBSAFE group. There was no difference in the rate of conversations about metabolic management or of new care plans as a result of conversations between groups. InterpretationWhile there was a difference in the types of conversations observed between the two study arms, this difference was small and only apparent in a few domains. Future work could aim to modify the QBSAFE cards to more effectively stimulate patient-centered discussions and to further prepare clinicians to respond to a variety of issues raised during the clinical visit.
