Furthermore, in managing the process, we had to face different dilemmas and challenges, and in this a sense of the role of the action researchers’ group, which had been formed for this intervention was helpful and supportive. In fact we were faced with two main limitations. One limitation was the possibility of evaluating outcomes and processes: some were assessed in itinere and ex post (e.g. change in representations; new actions and their impact; wealth of knowledge generated) while others, which derive from slower and more complex processes, are not easy to intercept and have not yet been able to be assessed, if not in the short to medium time frame (e.g. new modalities for managing differences and their impact on the organizational culture). A second limitation was represented by the precariousness and cyclical turnover affecting patients and their informal caregivers as well as practitioners (due to turnovers and staff reductions) raises the question of legacy and the handing down of knowledge and actions generated. In this case, the PAR's outcomes were successfully translated into new organizational dispositions for some goals (e.g. entry interview), but for others this did not occur (e.g. groups of informal caregivers who organized meetings and a system of mutual help).
