The intention is to improve coordination between the primary- and specialist health care sector. More specifically, the strategy is to transfer responsibility from specialist- to municipal health care services in order to improve quality and counteract the growth in health expenditures. To achieve the stated objectives, organisational, legislative and financial means are planned implemented. OBJECTIVE: To analyse the impact of supply of health care in Norwegian municipalities on use of specialist health care services, hereunder number of hospital admissions for specific diagnosis groups that are believed to hold a potential of being treated within municipal health care services to a larger extent. METHOD: The method used is a weighted least square regression incorporating “fixed effects” for health trust and year, analysing how number of hospital admissions for four main diagnosis groups are affected by supply of health care services in 427 Norwegian municipalities between 1999 and 2007. The thesis is based on diagnosis data that also form the basis for a separate thesis by Alejandra Palacio Perez, performing similar analyses with other relevant diagnosis groups. RESULTS: We find statistically significant and rather strong positive effects of number of municipal physicians and negative effects for general practitioner hospitals (sykestuer) on number of hospital admissions. In addition, we find negative effects of coverage of institutions for elderly. The results indicate that the number of hospital admissions increase with a higher number of man years of physicians. This finding is contrary to one of the means suggested in the white paper of increasing the number of GPs, hereby decreasing the pressure on specialist health care. Further, we find that municipalities that are covered by general practitioner hospitals have fewer admissions to somatic hospitals. Our analyses also indicate that high coverage of institutions within municipalities, results in reduced number of hospital admissions for elderly. 4 Table of contents Acknowledgements......................................................................................................................... 2 Abbreviations and acronyms ........................................................................................................ 3 Abstract ........................................................................................................................................... 4 Table of contents ............................................................................................................................ 5 List of figures .................................................................................................................................. 7 List of tables .................................................................................................................................... 8 1.
