Current features of peptic ulcer disease in Finland

Background: Medical therapy of peptic ulcer disease (PUD) has improved dramatically during the past 20 years with the introduction of modern antisecretory drugs as well as eradication therapy of Helicobacter pylori. During the 1990s, there has been a 3-fold increase in the consumption of histamine-2-receptor antagonists, and proton-pump inhibitors, but also an 8-fold increase in the consumption of nonsteroidal anti-inflammatory drugs (NSAIDs) in Finland. Methods: The incidence of surgery, hospital admissions and mortality for PUD was analysed between 1972 and 1999; the data were collected from the National Research and Development Centre for Welfare and Health and from the National Centre for Statistics. In the analysis, the codes of the International Statistical Classification of Diseases 8-10 were used. Results: In 1987, 11.9 elective operation, (per 10(5) inhabitants) were performed (mean of 2 consecutive years), but only 1.3 in 1997, a reduction of 89%, In 1987, 5.2 emergency operations for ulcer perforation or bleeding were performed, whereas there were 7.5 in 1997, an increase of 44%. The annual hospital admission rate increased from 38.3 admissions (per 105 inhabitants) in 1972 (mean +/- s (standard deviation) of 5 consecutive years) to 68.7 in 1992. This 79% increase was mainly due to bleeding from gastric ulcer in elderly women. The overall annual mortality rate increased between 1972 and 1992 from 6.4 to 8.4 deaths (per 10(5) inhabitants), i.e. by 31%. The mortality rate from ulcer perforation and haemorrhage increased from 4.2 deaths in 1972 to 7.3 deaths in 1992, i.e. by 74%. Conclusions: The increasing incidence rates of emergency surgery, hospital admissions and mortality for PUD in the 1980s and 1990s have started to decrease in the most recent years in Finland. This epidemiologic change probably reflects both the demographic change and an increased consumption of NSAIDS, among the elderly people, in particular. The most recent epidemiologic change may reflect an increased consciousness about the harmful effects of conventional NSAIDs. Regardless of the constantly occurring emergency surgery, elective surgery for PUD is hardly ever required today.
