OBJECTIVE: ) and the development of pneumonia related intensive care unit (ICU) patients and their lag effect. METHODS: 2 454 patients who lived in Nanchang City admitted to ICU of Jiangxi Provincial People's Hospital from January 1st, 2014 to December 31st, 2016 were enrolled. According to the diagnosis, the patients were divided into pneumonia group (156 cases) and non-pneumonia group (2 298 cases). The general clinical characteristics of patients and air pollution concentration in Nanchang in the year between 2014-2016 were collected. Multiple regression model was used to analyze the influence of meteorological factors on the condition of ICU patients associated with pneumonia. Using odds ratio (OR), the correlation intensity of air pollution exposure and pneumonia related ICU patients' development was reflected, and the confidence level of association intensity was reflected by the 95% confidence interval (95%CI). The distribution lag nonlinear model (DLNM) was established to evaluate the effect of air mass parameters on the time lag effect. RESULTS: , its effect on ICU pneumonia patients would last for 5 days (OR = 1.45, 95%CI = 1.07-1.76, P < 0.01). CONCLUSIONS: on ICU patients with pneumonia has a lag effect.
