Reducing low-value imaging-A qualitative evaluation of a pilot intervention in Norway.

Abstract

Low-value radiological imaging threatens patient safety and efficient use of limited health resources. It is important to evaluate measures for reducing low-value utilisation, to learnand to improve. Accordingly, the objective of this study was to qualitatively evaluate a pilot intervention for reducing low-value imaging in Norway. Semi-structured interviews were conducted aimed at describing stakeholders'experience with a multicomponent pilot intervention consisting of a standardised procedure for referral assessment, a standardised return letter, and information about the value and possible risks ofmagnetic resonance imaging-examinations to the public. Data were analysed in line with qualitative content analysis with a deductive approach. Seven healthcare providers were interviewed, including two radiologists, two radiographers, one manual therapist, one practice consultant and onegeneral practitioner. Data analysis yielded four categories: (1) information and reception,(2) referral- and assessment processes, (3) suggestions for improvement and facilitationand (4) outcomes of the pilot intervention. The pilot intervention was deemed acceptable, feasible, engagingand relevant. Specific training in the use of the new procedure was suggested to improve the intervention. The simple design, as well as the positive acceptance demonstrated and the few resources needed, make the pilot intervention and methodology highly relevant for other settings or when aiming to reduce the number of other low-value radiology examinations.
