Study Overview
Brief Summary
The main goal of this study is assess the effectiveness of a DA for patients with knee osteoarthritis candidates to ART
Detailed Description
The number of knee total arthroplasty (ART) interventions has increased in the last 10 years in European countries, partly due to the aging of the population and partly because of the increase in the use of these interventions to improve the quality of life among elderly patients. According to the Organization for Economic Cooperation and Development (OECD) 2012, from 2000 to 2010 in Spain the percentage of knee ART has doubled in recent years. .
The role of citizens in decisions affecting their health is changing. Individual factors such as improving educational attainment and access to medical information, and collective factors such as training of patient groups and changes in legislation (informed consent, autonomy principle) have motivated the transition from a paternalistic model to a co-responsibility model. Shared decision-making (TDC) has been proposed in recent years as a model of care that promotes users' involvement in the decisions about their treatment, in those situations where there is uncertainty and / or the scientific evidence reports a balance between benefits and risks that is similar for two or more therapeutic options. Decision aids (DA) are tools designed to promote and facilitate patients' involvement in medical decisions concerning their health

Arms & Interventions
Control group
In the control group, the usual explanation about the disease and the possibilities of treatment will be followed
Intervention group
In the Intervention group, the Decision Aid (DA) will be presented and explained to the patient by research personnel at a schedule previously agreed with the patient. The patient will be given a paper copy of the (DA) to take home, as well as a web link to the computer application, and oral and written instructions to review the material again and perform value clarification exercises.
Intervention: Decision aid (Other)
Outcomes
Primary Outcomes
Decisional conflict, measured by the Decisional Conflict Scale (DCS).
Time Frame: Immediately after the intervention; 6 months after the intervention (only non-operated patients)
The DCS measures patients' uncertainty about treatment choice. It is composed of five subscales: uninformed, values, support, uncertainty and effectiveness
Secondary Outcomes
- Knowledge of the disease and treatments(Immediately after the intervention; 6 months after the intervention (only non-operated patients))
- Goals and concerns(Immediately after the intervention; 6 months after the intervention (only non-operated patients))
- Treatment preference(Immediately after the intervention; 6 months (only non-operated patients))
- Satisfaction with the decision making process(Immediately after the intervention; 6 months)
- Decisional regret, measured by the Decisional Regret Scale (DRS)(6 months (only operated patients))
