Characteristics of Hospitalized Patients With Community-acquired Pneumonia

Study Overview
=================
Brief Summary
-----------------
At present, the epidemiological characteristics and the distribution of pathogens of community-acquired pneumonia in Shandong Province are not clear. In order to understand the characteristics of community-acquired pneumonia, the distribution of pathogens and the risk factors of complications in Shandong Province, it is necessary to carry out investigation and study, which will provide the basis and support for the future prospective cohort study of pulmonary infection.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The prevalence of CAP | The prevalence of CAP | Up to 12 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Severity Assessment: Curb-65 | Curb-65 is mainly used to evaluate the severity of pneumonia. The clinical indexes of curb-65 include: 1. Disturbance of consciousness, 2. Blood urea nitrogen > 7 mmol/L, 3. Respiratory frequency ≥30 times/min, 3. The severity of pneumonia 4. Systolic blood pressure < 90 mmhg or diastolic blood pressure ≤60 mmhg. 5. Age ≥65 years. If curb-65 score is 0-1, it is recommended that the patient be treated outside the hospital. Curb-65 has a score of 2 and is recommended for short-term hospitalization. If curb-65 score ≥3 indicates severe pneumonia, hospitalization or ICU treatment is recommended. With the increase of curb-65 score, the mortality of the patients will increase accordingly. | Up to 12 months | 
| Sputum culture | According to the need for aerobic bacteria culture, anaerobic bacteria culture, Mycobacterium tuberculosis culture, or fungal culture, for the etiological diagnosis of respiratory infection. | Up to 12 months |
