Primary outcomes

1. Time to Clinical Stability

   The criteria for clinical stability require meeting all five of the following indicators: Body temperature ≤ 37.8°C for more than 24 hours; Resting heart rate ≤ 100 beats per minute; Resting respiratory rate ≤ 24 breaths per minute; Systolic blood pressure ≥ 90 mmHg; Oxygen saturation (SpO₂) ≥ 90% (or arterial oxygen partial pressure ≥ 60 mmHg on room air). During the treatment period, log cards will be issued to monitor and record vital signs (temperature, respiration, blood pressure, heart rate, and SpO₂) every 12 hours. The time to clinical stability will be calculated based on these records

   Time frame: From the start of treatment, the time is recorded until the patient reaches clinical stability, whichever came first, assessed up to 2 weeks.

Secondary outcomes

1. Improvement of Clinical Symptoms

   Improvement in clinical symptoms is defined as at least two of the four main clinical symptoms (cough, sputum production, pleuritic chest pain, and dyspnea) showing an improvement of at least one grade, with no worsening of the other symptoms. The grade of clinical symptoms is divided into four levels: None Mild Moderate Severe The number of cases with clinical symptom improvement is calculated as the ratio of improved cases to the total cases in each group.

   Time frame: Evaluations will be conducted on Day 0, Day 4, Day 7, Day 14 (or at discharge) and during follow-up at 4 weeks and 12 weeks.

2. Length of Hospital Stay

   The length of hospital stay is calculated as the number of days from admission to when the patient meets the discharge criteria. Discharge Criteria include: Body temperature normal for more than 24 hours; Resting heart rate ≤ 100 beats/min; Resting respiratory rate ≤ 24 breaths/min; Systolic blood pressure ≥ 90 mmHg; Oxygen saturation ≥ 90% (or arterial oxygen partial pressure ≥ 60 mmHg on room air). If the patient can be transitioned to oral medication and does not require further management for complications or mental disorders, discharge may be considered.

   Time frame: From the start of treatment, the time is recorded until the patient discharge, whichever came first, assessed up to 2 weeks.

3. Confusion, Urea, Respiratory rate, Blood pressure, and Age ≥65 Score (CURB-65 score).

   The Confusion, Urea, Respiratory rate, Blood pressure, and Age ≥65 Score (CURB-65 score) is a clinical tool used to assess the severity of community-acquired pneumonia (CAP) and the associated mortality risk based on five clinical indicators(On a 5-point scale, 5 is the worst and 0 is the best.): Confusion (assessed by changes in mental status) ：0-5 score Urea (blood urea nitrogen level \>7 mmol/L) ：0-5 score Respiratory rate (≥30 breaths/min) ：0-5 score Blood pressure (systolic BP \<90 mmHg or diastolic BP ≤60 mmHg) ：0-5 score Age (≥65 years) ：0-5 score The total score is calculated by adding points for each indicator, with a higher score indicating more severe disease and higher risk of mortality.

   Time frame: The CURB-65 score is assessed on Day 0, Day 4, Day 7, Day 14 (or at discharge) and during follow-up at 4 weeks and 12 weeks.

4. Traditional Chinese Medicine Syndrome Efficacy Evaluation

   Based on the Guidelines for Clinical Research of Traditional Chinese Medicine New Drugs, each symptom is rated on a scale of None, Mild, Moderate, and Severe (4 levels). Primary symptoms (e.g., cough, sputum production, chest pain, and dyspnea) are scored 0, 2, 4, and 6 points, respectively. Secondary symptoms (e.g., fever, thirst, flushed face, yellow urine, constipation, and abdominal distention) are scored 0 or 1 point, depending on their presence or absence. For the Phlegm-Heat Obstructing the Lungs syndrome, the overall score is calculated by summing the points for primary and secondary symptoms before and after treatment. The treatment outcomes are classified into four levels: Clinical Recovery: Syndrome score reduction ≥95%. Significant Improvement: Syndrome score reduction ≥70%. Effective: Syndrome score reduction ≥30%. Ineffective: Syndrome score reduction \<30%.

   Time frame: These evaluations will be carried out on Day 0, Day 4, Day 7, Day 14 (or at discharge).

5. Comprehensive Clinical Efficacy Assessment

   Based on the Antimicrobial Drug Clinical Research Guidelines, the efficacy is classified into four levels: Clinical Recovery: At the end of treatment, the patient's clinical symptoms, signs, major laboratory tests, and microbiological tests have all returned to normal. Significant Improvement: At the end of treatment, the patient's condition has noticeably improved, but one of the four key indicators (symptoms, signs, laboratory tests, or microbiological tests) has not fully returned to normal. Progress: At the end of treatment, the patient's condition has shown some improvement, but not enough to be considered significant. Ineffective: At the end of treatment, the patient's condition has not improved or has worsened.

   Time frame: This evaluation will be conducted on Day 14 (or at discharge).

6. Modified Pneumonia Imaging Absorption Evaluation Scale

   Chest imaging examinations will be performed on both groups of subjects before and after treatment, as well as at the end of the follow-up, to observe the changes in lung imaging. The degree of pneumonia absorption will be recorded using the evaluation scale. Evaluation Process: Two radiology experts will independently assess and score the imaging results, and the average score will be taken. Assessment Points: The evaluations will be conducted on Day 0, Day 7 (or at discharge), and at 12 weeks during follow-up. This method helps assess the extent of pneumonia absorption and track changes in lung conditions over time.

   Time frame: The evaluations will be conducted on Day 0, Day 7 (or at discharge), and at 12 weeks during follow-up.

7. Pathogen Clearance Rate

   The microbiological results of both groups of patients during hospitalization will be recorded. Pathogen clearance is defined as follows: Clearance: If no pathogen is detected in more than three consecutive tests. Replacement: If the original pathogen is no longer detected and a new pathogen is identified. Not cleared: If the pathogen load does not decrease, or although the pathogen load has decreased, it has not been completely cleared.

   Time frame: This will be assessed at pre-treatment, Day 7, Day 14 (or at discharge) for each patient.

8. Readmission Rate

   The readmission rate includes the all-cause readmission rate and pneumonia-related readmission rate: All-cause readmission refers to patients being readmitted for any disease, with the admission criteria based on relevant disease guidelines. Pneumonia-related readmission refers to patients being readmitted due to a recurrent lung infection, with admission criteria based on the "Chinese Guidelines for the Diagnosis and Treatment of Adult Community-Acquired Pneumonia (2016 edition)", using the CURB-65 score to determine the need for hospitalization.

   Time frame: The readmission rate will be assessed at 4 weeks and 12 weeks during follow-up, with a detailed record of the reasons for readmission.
