Analyzing characteristics of basic syndromes of community acquired pneumonia and elderly patients with it.

Objective: To study characteristics of basic syndromes of community acquired pneumonia(CAP) and elderly patients with it. Methods: Data of CAP were collected in 4 hospitals. SPSS for windows ver.13.0 software was adopted for statistical description, χ2 test and Logistic regression. Results: Outcome indicated: ①There were 16 basic syndromes involving 1059 patients. The frequency and constituent ratio of syndrome of fi re-heat were the topmost (percent 45.8 and percent 17.14 ), then syndrome of sputum and heat(percent 38.9 and percent 14.57). ②Compared with pneumonia in the non-elderly, there were higher frequency with pneumonia in the elderly in defi ciency of lung qi, phlegmatic hygrosis, syndrome of defi ciency of kidney qi, syndrome of blood stasis, asthenia of pulmonary yin, defi ciency of spleen qi, wind-cold syndrome, defi ciency of kidney-yin and there was lower frequency in wind-heat syndrome(P0.05). There was no signifi cant difference in syndrome of fire-heat and syndrome of sputum and heat(P0.05). ③Common basic syndromes of CAP were wind-cold syndrome, wind-heat syndrome, syndrome of fire-heat, syndrome of sputum and heat, syndrome of phlegmatic hygrosis, deficiency of lung qi, deficiency of spleen qi and defi ciency of pulmonary yin. Meanwhile, the main symptoms and the sub-symptoms of the mainly syndromes were screened out by adopting statistical description, logistic regression. Conclusion: There were 8 common basic syndromes of CAP, which the most common were syndrome of fire-heat and syndrome of sputum and heat, and the elderly with CAP was usually combined with syndrome of defi ciency of qi or syndrome of yin defi ciency.
