[Diagnostic activity in general practice. 2. Frequency of examination of urinary glucose and blood pressure determination among patients in general practice].

In order to estimate how frequently examinations of urine for glucosuria and blood pressure measurements are performed in the primary health care sector to detect common incapacitating diseases such as diabetes and hypertension, the authors carried out a study in five general practices in Denmark for a period of five years. The study was retrospective because it is not possible to study one's own behaviour prospectively. Nearly 1,000 persons aged 30 years or more were involved. 9% of the group had no contact with the health care sector during the period. In 49%, the urine had been tested at least once for glucose; 58% where women were concerned but only 40% of the men. Men under the age of 55 years were significantly underrepresented. Examination of the urine was only undertaken in 51% of the persons aged 55-74 years. Twelve new cases of diabetes were discovered, nine of these were diagnosed in general practice. Hypertension had been diagnosed in 52 patients before the registration period. 60% of the remainder had blood pressure measurements on at least one occasion during the period. Men under 55 years were significantly underrepresented (42%). Sixty-four new cases of hypertension were discovered, 59 of these in general practice. Screening for common diseases such as these is primarily performed by general practitioner. Several other works from general practice where no special efforts were made to systematize screening for diabetes or hypertension did not reveal any better results. It is estimated that 25% of diabetic patients and 50% of hypertensive patients remain undiagnosed. The present rather random screening for these diseases is insufficient.(ABSTRACT TRUNCATED AT 250 WORDS)
