To study hospital physicians’ awareness and perceptions of the legal and financial regulations, and their impact on professional discretion regarding equity in access to treatment and quality of care. A sample of 637 physicians in the Norwegian specialist healthcare services selected from a survey conducted by the Institute for Studies of the Medical Profession. The paper investigates how legal and financial policy instruments affect the application of professional discretion regarding the prioritisation of specialist health services. Descriptive statistics and regressions were (...) conducted for the analyses. Compared with financial incentives, legal regulations (laws, priority rules and guidelines) were assessed to be less negative external interventions in the exercise of medical and professional judgement. The empirical analyses revealed a positive tendency in physicians’ assessments of the impact of legal regulations on treatment equity and healthcare quality, but negative attitudes towards financial instruments. The variations revealed are attributable to various structural and epistemic features of the legal–bureaucratic and economic models of administration in this area of the welfare state. Legal and financial regulations are imposed to achieve certain social goals and values. The findings of this study can provide further insight for the health authorities in other countries concerning implementation of such regulations in the specialist healthcare services. (shrink)
