Abstract:

Objective To acquire data regarding to the incidence and prevalence of pneumonia requiring hospitalization in Shanghai, China. Methods All patients with diagnosis recorded using International Classification of Diseases Tenth Revision (ICD-10), discharged or died from any medical institutions in Jiading District of Shanghai, from 2013 to 2018, were screened. The clinical data of patients with pneumonia and main diagnosis coded in J13-J18 were collected. The number of residents in Jiading District from 2013 to 2018 was taken from the Shanghai Statistical Yearbook; the gender and age composition ratio were uniformly taken from the 1% population sampling survey in Shanghai in 2015. Results From 2013 to 2018, there were 598 598 discharged patients in Jiading District, including 25 204 patients(4.21%) with pneumonia as the main diagnosis. The average length of hospitalization was 11.5 d, and the average hospitalization cost was 6 921 yuan. The annual incidence of pneumonia requiring hospitalization was 2.67 per 1 000 population. The highest prevalence was found in the infants lower than 1 year old, 38.09 per 1 000 population, and the incidence declined dramatically in elder population, with the lowest annual incidence, 0.23 per 1 000 population, observed in age group of 25-29 years. The incidence increased in elder population and age group of over 95 years old had an annual incidence of 19.81 per 1 000 population. The incidence in men under 5 and above 70 years old was significantly higher than that in women of the same age group. The incidence rate of pneumonia in man with 5-9 years old, 20-34 years old and 50-59 years old was significantly lower than that in women of the same age group. The average inhospital mortality of pneumonia was 1.75%. The mortality of children, adolescents, young and middle-aged patients was very low. The mortality of elderly patients was higher and increased with age. The mortality rate of 90-94 years old group was 11.28%. Conclusions The annual incidence rate of pneumonia in Jiading District is 2.67 per 1 000 population. The incidence and mortality in the elderly are very high. The prevention and treatment of pneumonia in elderly is an important issue in the aging of population.
