Effect of an educational program for general practitioners on Gotland on the pattern of prescription of psychotropic drugs.

During the years 1983-1984, an educational program was given to all general practitioners on the island of Gotland. This report evaluates changes in prescription habits from 1982 to 1985. To correct for general trends that occurred simultaneously, the prescription habits were compared to the habits in the rest of Sweden. Both on Gotland and in Sweden as a whole, the use of antidepressants increased from 1982-1985, but significantly more on Gotland. In 1982, the use of antidepressants was low on Gotland, 54% of that in the rest of Sweden. After the educational programs, Gotland reached 77% of the use in the rest of Sweden. In 1982, the use of lithium was 123% of that in the rest of Sweden. After the educational programs, the use of lithium was unchanged, and a small increase of 5.6% was seen in the rest of Sweden. After the educational programs, the prescription of sedatives on Gotland decreased (-8.2%), and an increase of 4.5% was seen in the rest of Sweden. The use of major tranquilizers also decreased significantly (-23%) on Gotland. Even in the rest of Sweden, a significant but much smaller decrease was seen: -13%. On Gotland the frequency of hypnotics remained stable from 1982-1985, and a significant increase was seen in the rest of Sweden.
