Objective To study elderly patients with severe pneumonia risk factors and prognostic factors.MethodsBy a case-control study,collection 101 case from Fujian Provincial Hospital ICU in June 2007 ~ December 2008 of elderly(≥65 years) pneumonia patients,62 cases are elder severe pneumonia,set it to case group,and the remained 39 cases of elder non-severe pneumonia as the control group.Univariate analysis(chi-square test and rank sum test) and multivariate Logistic regression were used for statistics analysis.ResultsThe average age of patients is [mean age(79.32±6.71) years],the total number of hospitalization days is [mean(53.53±60.12) days],the number of hospitalization days in ICU is[mean(33.08±48.77) days],fatality rate is 32.25%.The main pathogen is gram negative bacilli(62.69%),acinetobacter baumannii occupied 25.37%.Multivariable logistic regression analysis showed that: Fine ⅣⅤ,respiratory failure,PT13.0S and TBIL17.0 μmol/L are the independent risk factors of occurred elderly severe pneumonia.Haemoglobin 90 g/L,mechanical ventilation and FineⅤ are independent predictive factor.ConclusionFine ⅣⅤ,respiratory failure,PT13.0S and TBIL17.0 μmol/L are the independent risk factors of occurred the elder severe pneumonia.Haemoglobin90 g/L,mechanical ventilation and FineⅤare independent predictive factor.Fine′s risk classification has great value in elderly patient′s condition assessment and prediction of prognosis.
