Abstract
BACKGROUND: Measurement of person-centred care (PCC) outcomes is underdeveloped owing to the complexity of the concept and lack of conceptual clarity. A framework conceptualizing outpatient PCC in rheumatology nurse-led clinics has therefore been suggested and operationalized into the PCC instrument for outpatient care in rheumatology (PCCoc/rheum). OBJECTIVE: The aim of the present study was to test the extent to which the PCCoc/rheum represents the underpinning conceptual outpatient PCC framework, and to assess its measurement properties as applied in nurse-led outpatient rheumatology clinics. METHODS: The 24-item PCCoc/rheum was administered to 343 persons with rheumatoid arthritis from six nurse-led outpatient rheumatology clinics. Its measurement properties were tested by Rasch measurement theory. RESULTS: Ninety-two per cent of individuals (n = 316) answered the PCCoc/rheum. Items successfully operationalized a quantitative continuum from lower to higher degrees of perceived PCC. Model fit was generally good, including lack of differential item functioning (DIF), and the PCCoc/rheum was able to separate individuals with a reliability of 0.88. The four response categories worked as intended, with the exception of one item. Item ordering provided general empirical support of a priori expectations, with the exception of three items that were omitted owing to multidimensionality, dysfunctional response categories and unexpected ordering. The 21-item PCCoc/rheum showed good accordance with the conceptual framework, improved fit, functioning response categories and no DIF, and its reliability was 0.86. CONCLUSION: We found general support for the appropriateness of the PCCoc/rheum as an outcome measure of patient-perceived PCC in nurse-led outpatient rheumatology clinics. While in need of further testing, the 21-item PCCoc/rheum has the potential to evaluate outpatient PCC from a patient perspective.
