title: Treatment of diabetes mellitus--physicians' adherence to clinical guidelines in Norway.
abstract: OBJECTIVE
  To assess general practitioners' current adherence to the Norwegian clinical guidelines for the treatment of diabetes mellitus.
  
  
  METHODS
  Descriptive, retrospective registration of information from patient records of one year; 7 November 1993 to 7 November 1994. In addition, mailed questionnaire to examine the representativeness of the participating doctors.
  
  
  METHODS
  General practice in Sør- and Nord-Trøndelag counties in Norway, 380,000 inhabitants.
  
  
  METHODS
  In one year 1119 patients were registered with the diagnosis of diabetes mellitus in the records of 56 general practitioners. The patients were 53% women and 47% men; 51% were 70 years or older.
  
  
  METHODS
  Levels of HbA1c and blood pressure in accordance with the recommendations of the Norwegian clinical guidelines for diabetes mellitus. Fractions of patients with a measured HbA1c, blood pressure, and serum cholesterol in one year.
  
  
  RESULTS
  At least one HbA1c was recorded in 77% of the diabetic patients during the specified year. In patients under 70 years of age, 56% had HbA1c above the recommended treatment level of 7.5%. In patients 70 years of age or older, 36% were above the recommended limit of 8.5%. At least one blood pressure was recorded in 79% of the patients during the specified year. In patients under 70 years of age, 53% had a systolic blood pressure above the recommendations of 140 mmHg, and 22% had a diastolic blood pressure above the recommendations of 90 mmHg. Serum cholesterol was not recorded during the specified year in 75% of the patients.
  
  
  CONCLUSIONS
  There are still major discrepancies between current practice and the intentions laid down in the Norwegian clinical guidelines. A discussion of alternative methods for implementation and evaluation of the efficacy of clinical guidelines is needed.
