BACKGROUND By the year 2030, estimates suggest that there will be 74.7 million people with different forms of dementias worldwide. There is no cure for dementia, but several non-pharmaceutical interventions are constantly tested and updated to improve patients quality of life. These include, for instance, interventions to increase communication skills, reduce agitation and stress management, and use of new technology. Unfortunately today direct care workers are systematically excluded by accessing such up-to-date evidence to improve their work. This group of workers paradoxically face the highest demanding work situations, being at the same time the most burdened group and the least trained one. Vocational training opportunities for them are totally inadequate OBJECTIVES OF THE PROJECT iDO project mission is to make evidence-based knowledge available for workers in dementia care, reaching professionals who are normally excluded from training opportunities. The project objectives are to: 1) design and develop in close collaboration with people with dementia and their caregivers an innovative training package to promote the acquisition of skills and competences; 2) test the training package with an appropriate number of direct care workers in five EU countries, especially for evaluating its impact on their motivation and inclusion in learning activities; 3) finalize the training package incorporating all feedbacks from end-users; 4) disseminate and scale up the intellectual outputs at a wider EU level, ensuring the sustainability of project results. NUMBER AND PROFILE OF PARTICIPANTSIn an interactive, stepwise co-design and co-production process, we included approx. 2800 participants, including direct care workers (primary target group), people with dementia, their family caregivers, professionals engaged in dementia care (secondary target group) as well as adult studying to qualify as health care and social services professionals. A similar number of men and women were included, aged 20-87. ACTIVITIES AND METHODOLOGY The training package aimed at addressing current barriers to training opportunities among our primary target group, includes eight modules comprising: • testimonial videos created by caregivers and people with dementia explaining their needs and aspirations (Intellectual Output, IO1); • a series of training videos by expert professionals on dementia care good practices, advices and tips on how to improve daily practice routines and address the needs expressed by users (IO2);- In the end of each module a short quiz has to be passed in order to unlock the serious game described below • an interactive serious game was developed in order to enable direct care workers to manage virtually a series of case scenarios and to learn through problem-solving activities (IO3). The game comprises different scenarios common in daily life. The response to the scenarios are measured in terms of dementia care outcomes and can be followed on the screen while playing. Focus group interviews with people with dementia and their family caregivers were held in Sweden, Italy, Greece and Portugal. The findings were analysed applying manifest content analysis and were used as the basis for the development of the testimonial and expert videos (IO1and IO2) MOOC (IO4) and the serious game (IO3). Data for the dementia care outcome indicators in the serious game (IO3) were generated by means of a review of randomised controlled trials published during the previous ten years. Data from the studies were extracted using regression analyses to generate the outcome indicators.All material is included in the Massive Open Online Course (MOOC) (IO4) developed and implemented on the Udemy platform. RESULTS AND IMPACT The iDO MOOC (on Udemy) and serious game is publicly available and usable by mobile devices, free of charge in English, Greek, Italian, Lithuanian, Portuguese and Swedish. The MOOC comprises 8 modules on state-of-the-art dementia knowledge, each of them ending with at short quiz, where correct answers unlock more advanced parts of the game. The game and the MOOC are connected via the website idoproject.eu. The MOOC and game seems to improve direct care workers empathy and understanding towards people with dementia and their family carers; it improves their knowledge, skills and competences on dementia care and provides practical tips of best practices interventions in dementia. The game and MOOC have been used by 800+ users and the evaluation of the training package is positive. LONGER TERM BENEFITSConsidering the longer term benefits of iDO results, they are not possible to evaluate yet. However, with the increasing shortage of time possible to allocate for staff education and training, online training tools such as the iDO platform are requested, with high potential to benefit staff, persons with dementia and their caregivers positively.
