Motivational Interviewing in the Control of Arterial Hypertension and Type 2 Diabetes Mellitus

The goal of this study is to evaluate the effectiveness of Nursing Consultation based on the assumptions and techniques of Motivational Interviewing for the control of Type 2 diabetes mellitus with associated diagnosis of Systemic Arterial Hypertension in primary healthcare.

Type 2 Diabetes Mellitus and Systemic Arterial Hypertension are major challenges to health systems worldwide, and control, adherence and promotion of self-care are the cornerstone of their management. In this context, an adequate therapist-patient relationship is the key to the success of these interventions in healthcare, and nurses have a recognized and outstanding role in improving adherence and care results in chronic diseases. Motivational Interviewing (MI) emerges as a skillful method of counseling that has proven to be effective in promoting changes in a wide variety of health-related behaviors, including hypertension and diabetes. Despite the increasing number of international studies in different health fields, the scientific production that assess the applicability of Motivational Interviewing to chronic diseases in the Brazilian setting is still modest. Recent studies suggest the need for further research involving the discussion and improvement of studies utilizing Motivational Interviewing in Brazil, as well as in other countries around the world, for better outlook on this area of investigation. Therefore, this study intends to contribute to this perspective and aims to investigate the effectiveness of this care strategy in individual Nursing consultations for people with DM2 and SAH who are being treated in three Primary Healthcare Clinics in the Northern Area of Porto Alegre - RS , Brazil, which are an integral part of the Grupo Hospitalar Conceição (GHC) Community Health Service (SSC). GHC treats patients from the Brazilian public health system exclusively, with universal and free access, and the SSC is comprised of 16 primary care and mental health services, caring for a population of 105,000 inhabitants in the northern and eastern areas of Porto Alegre, RS, Brazil. This will be a randomized, controlled, parallel and double-blind clinical trial to be conducted in the period from June to September, 2018.
