Résumé
Objective To retrospectively study the etiology of patients with community-acquired pneumonia-like syndrome in Zhangjiakou area in the past 3 years, and to provide guidance for clinical rapid diagnosis and empirical treatment. Methods A total of 471 patients with community-acquired pneumonia-like syndrome were initially diagnosed in the outpatient or inpatient hospitals in Zhangjiakou area from August 2015 to August 2018. According to the age of the cases, they were divided into the youth group (age≤29 years old, n=89), the junior middle-aged group (30≤age≤39, n=124), the middle-aged group (40≤age≤49, n=177) , and the elderly group (age≥50, n=81). The clinical records of each group of patients were collected to explore the clinical features and etiology of community-acquired pneumonia-like syndrome in different age groups. Results (1)The comparison of the duration of disease in each group showed that the duration of disease in the youth group was significantly lower than the average, while the duration of the elderly group was significantly higher than the average. There was no significant difference in the duration of the disease between the junior middle-aged and middle-aged groups; (2)Seasonal statistics of community-acquired pneumonia-like syndrome found that the overall incidence rate in autumn (48.20%) was higher than that in spring (13.06%), summer (16.77%), and winter (21.97%). The incidence in the elderly group mainly occurred in autumn and winter, which was significantly different from the other three groups; (3)The comparison of the CURB-65 scores revealed that the youth and the junior middle-aged groups were mainly at low-risk (57.30%, 65.32%), the middle-aged group was at low-risk and intermediate-risk (40.68%, 50.28%), and the elderly group was mainly at intermediate-risk and high-risk (29.01%, 33.33%). All the differences were statistically significant (P<0.05). Conclusion The community-acquired pneumonia-like syndrome in Zhangjiakou area was predominantly high in autumn, and was common in the elderly population. The disease was more serious with a longer course in the elderly group than other populations, which should be paid attention to in clinical practice.
