The Person-centred Climate Questionnaire is a valid and reliable contribution for assessing to what extent the climate of hospital environments is person-centred. The instrument enables descriptions and comparisons of environments, exploration of correlates between person-centredness and patient outcomes and/or measure results of various interventions.

The proposed substantive theory can be used to critically examine current ward practices and routines, and the extent to which these support or inhibit high-quality person-centred care for older patients with known or unknown cognitive impairments.

The comprehensive understanding indicates that being a nurse and having to care for older patients in acute care settings means providing nursing care in an environment that does not support possibilities to protect and develop nurses' personal-professional integrity.

This instrument makes it possible to study the degree of person-centredness in relation to different organizational systems, environments, staff groups and managerial styles. In addition, staff variables such as turnover rates, health outcomes and efficacy can be related to staff perceived person centredness of the organization.
