Background:
The integrated uptake of patient-reported experience measures, using outcomes for the micro, meso and macro level, calls for a successful implementation process which depends on how stakeholders are involved in this process. Currently, the impact of stakeholders on strategies to improve the integrated use is rarely reported, and information about how stakeholders can be engaged, including care-users who are communication vulnerable, is limited. This study illustrates the impact of all stakeholders on developing tailored implementation strategies and provides insights into supportive conditions to involve care-users who are communication vulnerable.

Methods:
With the use of participatory action research, implementation strategies were co-created by care-users who are communication vulnerable (n = 8), professionals (n = 12), management (n = 6) and researchers (n = 5) over 9 months. Data collection consisted of audiotapes, reports, and researchers’ notes. Conventional content analysis was performed.

Results:
The impact of care-users concerned the strategies’ look and feel, understandability and relevance. Professionals influenced impact on how to use strategies and terminology. The impact of management was on showing the gap between policy and practice, and learning from previous improvement failures. Researchers showed impact on analysis, direction of strategy changes and translating academic and development experience into practice. The engagement of care-users who are communication vulnerable was supported, taking into account organisational issues and the presentation of information.

Conclusions:
The impact of all engaged stakeholders was identified over the different levels strategies focused on. Care-users who are communication vulnerable were valuable engaged in co-creation implementation strategies by equipping them to their needs and routines, which requires adaptation in communication, delimited meetings and a safe group environment.

Plain English summary
Exploring care-users experiences is important for decisions to improve quality of care. This applies to care-users in the disability care in particular, as these care-users are highly dependent on their care professional. Instruments that facilitate a dialogue between care-users and care professionals about experiences with care are not always used correctly. Furthermore, it is difficult to translate outcomes into decisions about improving quality of care for the individual care-user and the organisation. In our study, care-users, care professionals, management and researchers developed strategies together to improve the use of care-user experience measures.
This study aims to show the impact of all participants, including care-users, professionals, management and
researchers, on developing implementation strategies. Additionally, the study aims to show how care-users can participate in developing strategies whilst having problems with communication due to intellectual, developmental and acquired disabilities.
We found that care-users gave crucial input to the look and feel, and understandability and relevance of the strategies. The contribution of the professionals had impact on how to use strategies and terminology used in instructions and visuals. Management shared lessons learned and represented the needs on the policy level. Researchers used their analytical skills and facilitated the group process. Care-users were able to collaborate by taking into account their needs and because information was presented to them clearly and attractively.
