The 3 dimensions of BPSD support systems, i.e. structures and care organisations (1, SCO), Individualised patient and family carer interventions (2,IPCI) and workforce & skills (3,WFS), are independent and represent 3 “orthogonal” axes resumed as a “3D view”. All combinations involving some particular SCO, applying diverse IPCI (i.e. non pharmacological interventions) and some WFS (i.e. trainings and skills may be thus considered).
The “3D view” is not fully taken into consideration in literature since numerous interventions combine the evaluation of SCOs, such as day care centres, IPCI, such as psychosocial interventions, and WFS, such as specific professional education programmes. Furthermore, most of the studies mix functional, cognitive and behavioural evaluations, both in the patient and the carer. To disentangle these multiple interventions and approaches helps to better evaluate them, and more importantly, to consider the best combination.
