Background/aim: Legislators and health care organisations in Sweden have put person-centred care (PCC) high on the development agenda. However, the knowledge about costs associated with introducing a more PCC is limited and scattered. Overlooking such costs, however, implies that the time added for this implementation is minimal and can be ignored. This study aimed to describe the time and costs used during the implementation of a more PCC approach as part of ordinary practice. Methods: A case study with embedded units was conducted in Region Dalarna, Sweden. Participants included the Department for Development (DD) staff who provided a central support function in the implementation and six healthcare units: nephrology, two geriatric care and rehabilitation units, two psychiatry units, and primary care. Logbooks were used to identify time spent for implementation strategies, service delivery, and research/development costs. Administrative data and mean salaries were used to estimate costs for these activities. Results: The health care units logged on average 5.5 working days per staff member. In the healthcare units, 6-57% of the time reported was used for implementation strategies, 40-90% for service delivery, and 2-12% for research/development. Of the time reported by the DD, 88% was assigned to implementation strategies. Costs associated with reported time indicated 23% of costs for this implementation occurred in the DD. Using the budgeted cost, this proportion increased to 48%. The budget for the DD corresponded to SEK 2.30 per citizen per year and 0.009 % of the total health care budget of the region. Conclusions: The study found that a large part of resources used for this implementation of more PCC occurred in the DD, although at least half of the costs occurred in the healthcare units. Moreover, the cost of the central support function corresponds to a tiny proportion of the total health budget.
