Abstract：Objective To explore the the clinical value of serum C-reactive protein （CRP）and procalcitonin （PCT）in the early diagnosis of hospital acquired pneumonia（HAP）in elderly patients. Methods 72 elderly patientswith HAP in our hospital from November 2013 to December 2015 were selected as the observation group，65 normal healthy individuals with the same period were selected as the control group.Blood samples of the observation group were extracted when patients hospitalized and early clinicalmanifestation arising and diagnosis determined，which of the control group were extracted on the day of physical examination.The level of CRP and PCT was compared between the observation group on admission and the control group，and the level of CRP and PCT in the observation group on admission，early clinical manifestation arising，diagnosis determined was compared.Results There was no significant difference in the serum CRP and PCT levels between the control group and the observation group who hospitalized （P＞0.05）.The serum CRP and PCT levels of the observation group when early clinicalmanifestation arising was higher than that in the same group when patients hospitalized，with significant difference （P＜0.05）.The serum CRP and PCT levels of the observation group when early clinicalmanifestation arising was lower than that in the same group when diagnosis determined，with significant difference（P＜0.05）.Conclusion The serum CRP and PCT levels in elderly patientswith HAP in early clinicalmanifestations but not yet confirmed can significantly increase，which have an important clinical significance in early diagnostic value on elderly patientswith HAP.
