Improving Communication and Healthcare Outcomes for Patients With Communication Disabilities: The INTERACT Trial

About 40 million people have a communication disability (CD), which includes hearing, speech, language, and voice disabilities. Compared to non-disabled patients, patients with CD are more likely to have a greater number of chronic conditions, and have higher rates of asthma, hypertension, emphysema, cardiovascular disease, diabetes and arthritis. Approximately one third of people with CD report the quality of their health as fair/poor as compared to only 11% of patients without CD. Patients with CD are 2-4 times more likely to report difficulty finding a provider than those without CD. When they do access care, they report that the quality of care and communication they receive is low.

Communication strategies that patients with CD require may vary, and providers need to elicit and then adapt to patients' preferences for communication strategies. Provider education and patient-prompt tool interventions have demonstrated effectiveness in general populations. Provider communication education significantly improves their patient-centered communication. Patient-prompt tools empower patients to identify topics and communication styles they prefer and then share this information with their healthcare provider. While provider education and patient-prompt tools have been proven effective, their effectiveness has not been compared in the primary care setting for patients with CD. Therefore, the aim of this study is to adapt these two types of interventions for patients with CD in the primary care setting and then compare their effectiveness at improving patient-reported health related quality of life and experience with care.

In this study we will conduct a stepped-wedge randomized control trial design. The study will take place at 4 sites that have unique contributions that will add to the generalizability and dissemination of the results. They are diverse in their geographic location, include academic and community clinics, represent urban and suburban locations, and include racially and ethnically diverse patients. Eight clinics, 2 at each site, will be part of the trial.

All participating clinic sites will receive the healthcare team-directed intervention (intervention A) and then will be randomized as to when they begin implementing the patient-directed tool (intervention B). The A versus A+B study design ensures all participating healthcare team members receive the training, as national policies require healthcare team members receive training on effective communication with patients with CD. We will randomize at the clinic-level cluster to eliminate spillover intervention effects amongst providers within the same clinic.

Participating healthcare team members will all receive the healthcare team-directed intervention (a general overview training about communication disabilities and communication strategies that can be used with patients) during the month preceding trial roll-out. Clinics will be randomized as to when they begin implementing the patient-directed tool, with a new clinic beginning every two months. One month prior to implementation, the healthcare team members will receive a booster education training, be introduced to the patient-directed tool, and alerted that they will be handed the completed tool by patients with CD during the patients' clinical encounters.
