Mortality and autopsy rate for respiratory diseases in Finland in 1955--1973.
Mortality from respiratory diseases in Finland in 1955--1973 was investigated using the official statistics and original death certificates. Total mortality from respiratory diseases in men was significantly higher than in women. Total respiratory mortality in men has increased slightly since 1963, whereas in women it decreased between 1955 and 1963 but has since remained almost constant. Mortality from lung cancer increased in men constantly in the years 1955--1973, but this was not found in women. Mortality from obstructive lung diseases in men increased slightly between 1955 and 1969 but not since. This increase was recorded only for the elderly whereas the opposite trend was found in younger people. The number of deaths from pneumonia decreased between 1955 and 1963. After 1963 these deaths increased again but only in the older age groups. Mortality from pulmonary tuberculosis showed a steady decrease. In 1973 the autopsy rate was 80.6% in pneumococcal pneumonia, 65.6% in pulmonary embolism, 48.1% in bronchiectasis, and 47.0% in pulmonary tuberculosis, exceeding significantly the mean national autopsy rate which was 38.3%. This might mean that at least some of these respiratory diseases are underdiagnosed clinically as the performance of an autopsy seems to increase their relative proportion in mortality statistics.
