[Significant regional differences in the frequency of vascular surgery].
The six health care regions of Sweden were compared with regard to the frequency of vascular surgery for three diagnoses: chronic lower extremity ischaemia, abdominal aorta aneurysm, and carotid stenosis. In 1995, the frequency of intervention for chronic lower extremity ischaemia varied from 26/100,000 of the population in northern Sweden to 68/100,000 in the southern region, the variation being greater for critical limb ischaemia than for intermittent claudication. In the country as a whole, the frequency of abdominal aorta aneurysm surgery increased five-fold from 1987-89 to 1993-95. During 1995, regional figures varied from 4.7 to 8.4 per 100,000 for elective procedures, and from 3.8 to 5.5 per 100,000 for emergency procedures. Overall surgical mortality varied regionally, and emergency surgery mortality differed between regional and county hospitals. Carotid surgery manifested the greatest regional difference in frequency, which was 7-fold greater in the southern than in the northern region, while its overall mean frequency was 6/100,000.
