Effectiveness of a Diabetes Education Program based on Tailored interventions and Theory of Planned Behaviour: Cluster randomized controlled trial protocol.

Abstract

Aim: To measure the Effectiveness of a Diabetes Education Program for people with T2DM, based on Tailored interventions and the Theory of Planned Behaviour. Design: Cluster randomized controlled clinical trial. Methods: This multicentre study will be carried out at 30 primary healthcare centres, where 436 persons with Type 2 Diabetes Mellitus (T2DM), aged between 18–75 years, will be recruited. The experimental educational program to be applied is modelled using components obtained from a systematic review and prior qualitative analysis. In addition, a taxonomy of nursing practice is used to standardize the program, based on the Theory of Planned Behaviour as a conceptual model. The intervention will be carried out by community nurses, using ADAPP-Ti®, an application developed with FileMaker Pro v.18. The control group will receive usual care and data will be collected at 6, 12, and 18 months, for both groups. The primary outcome considered will be glycosylated haemoglobin and cardiovascular factors, while the secondary ones will be tobacco consumption, body mass index, barriers to self-care, health-related quality of life, and lifestyle modification. The protocol was approved by the Ethics Committee of the Province of Malaga (Spain) in November 2014. Discussion: The degree of metabolic control in T2DM is not always associated with healthy lifestyles and significant levels of medication are often prescribed to achieve clinical objectives. An intervention focused on needs, based on the best available evidence and a solid conceptual framework, might successfully consolidate appropriate self-care behaviour in this population. Impact: The study will result in the publication of an educational program featuring well-defined interventions and activities that will enable clinicians to tailor health care to the individual's needs and to combat treatment inertia in attending this population.
