title: [Electroconvulsive therapy in the Ullevaal region of Oslo 1988-2002].
abstract: BACKGROUND
  Electroconvulsive treatment (ECT) has been used less frequently in Norway than in Denmark and Sweden. The aim of this investigation was to study the use of ECT in female and male patients in different age-groups in the Ullevaal region of Oslo from 1988 to 2002, and to compare the results with studies in Denmark and Sweden.
  
  
  METHODS
  The protocols of ECT treatments in three clinical departments serving the Ullevaal region and relevant population data were used to calculate the annual number of ECT courses per age- and gender-specified population groups of 100,000.
  
  
  RESULTS
  Use of ECT increased progressively from 2.3 to about 20 patients per 100,000 per year (p < 0.001). In the late 90s the increased use of ECT approached the use in Denmark and Stockholm. From 1988-92 to 1993-97 the use of ECT increased significantly in all age groups in women and men above 70 years. From 1993-97 to 1998-2002 the increase was significant in women and men above 70 years. From 1998 to 2002 the annual rates of ECT increased with increasing age for both sexes. In women aged > or = 70 years the rate of ECT was only 1.5 times higher than in men.
  
  
  CONCLUSIONS
  The study confirms increased use of ECT in the Ullevaal region after 1988. The use of ECT in this region approached the decreased use in Denmark and Stockholm. The increased use occurred particularly in patients above 70 years.
