RESULTS: (1) The most autopsy cases is 1037 cases during 1960 - 1970, while the lowest is 102 cases during 1990 - 1999. (2) The total clinical mis-diagnosis rate is 36.24%, while the highest one is 43.19% in 1970 - 1979 group, and 41.80% in 1990 - 1999; The highest diagnostic inaccuracy rate is for tumor (62.42%), second circulation disease (61.81%), third parasitic disease (49.18%); Invasive fungal infection rate in 3162 autopsy is 2.28%, while the diagnostic inaccuracy rate is as high as 86.10%. (3) In disease spectrum, the common diseases are respiratory disease (32.29%), infectious disease (11.61%) and digestive disease (11.07%) respectively. CONCLUSION: The autopsy rate was decreased gradually over 50 years, while the diagnostic inaccuracy rate is still high.
