Influencing factors of hospitalization cost and mortality of patients with pulmonary infection / 中国感染控制杂志

ABSTRACT

Objective To investigate the hospitalization cost,length of stay in hospital,and mortality in patients with pulmonary infection in a hospital,and evaluate the influencing factors,so as to provide scientific basis for mak-ing targeted infection control measures.Methods Medical records of patients with pulmonary infection between January 2011 and December 2012 were collected,the difference and influencing factors of hospitalization cost,aver-age length of stay,and prognosis among patients with different types of pulmonary infection were compared and an-alyzed by univariate analysis,multiple linear regression analysis,and logistic regression analysis.Results Of 10 431 patients with pulmonary infection,the average hospitalization cost was (29 081 .95 ± 38 682.92 )yuan (RMB),the median cost was 16 085.25 yuan(RMB),and the average length of stay was (15.93 ±20.54)d,the median was 13.00 d,a total of 828 patients died due to invalid treatment,mortality was 7.94%.There were signifi-cant differences in hospitalization cost,average length of stay among patients with different genders,ages,modes of payment,admission status of illness,types of pulmonary infection,and operation or not (all P <0.05),and the differences in mortality were also significant among patients of above characteristics except gender(all P <0.05 ). Influencing factors for hospitalization cost were as followslength of stay,whether or not operated,modes of pay-ment,types of pulmonary infection(healthcare-associated pneumonia,HAP),age,gender,and so on,influencing factors for length of stay were whether or not operated and types of pulmonary infection,factors leading to death were admission condition, types of pulmonary infection (HAP ),and whether or not operated, and so on. Conclusion Control of healthcare-associated pulmonary infection is important for controlling hospitalization cost, shortening average length of stay,and improving survival rate of patients.
