Since 2022, the Third Affiliated Hospital of Sun Yat-sen University has initiated the "Hot Wave Project", a comprehensive hepatitis B infection prevention and management system encompassing patient education, screening, referral, treatment, and follow-up. In 2024, this system was expanded to the Sixth Affiliated Hospital and the Fifth Affiliated Hospital of Sun Yat-sen University, transitioning into a multicenter, hospital-based cohort study on hepatitis B management.The primary objective of this study is to increase the referral rate of HBsAg-positive patients in non-hepatology/non-infectious disease departments to 50%. The secondary objective is to improve the treatment rate of hepatitis B infected patients in non-hepatology/non-infectious disease departments, particularly focusing on the diagnosed but untreated (DBU) population. Furthermore, this study aims to analyze the cost-effectiveness and clinical benefits of in-hospital hepatitis B screening and management strategies.In 2025, a Patient-Reported Outcomes (PRO) sub-study was added to the project to evaluate the impact of antiviral therapy on the Health-Related Quality of Life among a cohort of treatment-naïve patients with chronic hepatitis B.
The "Hot wave Project" aims to establish a multicenter management cohort for HBsAg-positive patients within hospitals. Led by infectious disease specialists, the program conducts regular hepatitis B training sessions for hospital staff to enhance their understanding of HBV prevention and control. This initiative seeks to increase HBsAg screening rates overall and encourage patients from non-infectious disease departments to seek referrals to specialized care.
For all paper reports containing HBsAg test results, a remark is added stating: "HBsAg (+) - Recommended to visit the Hepatitis B Health Clinic in the Infectious Disease Department." Positive HBsAg results are automatically extracted by the information system and sent to a dedicated computer in the Hepatitis B Health Clinic, enabling centralized digital patient management.
Additionally, the Infectious Disease Department appoints a "Hepatitis B Specialist Assistant" responsible for reviewing HBsAg screening results, notifying HBsAg-positive patients or their attending physicians, and establishing follow-up records for all patients. A "Hepatitis B Health Clinic" is also set up within the department, managed by a specialized medical team that handles the diagnosis, treatment, and education for referred chronic hepatitis B patients.
Building upon this comprehensive management cohort, the project was expanded in 2025 to include a prospective Patient-Reported Outcomes (PRO) sub-study. This sub-study is designed to evaluate the longitudinal impact of antiviral therapy on the Health-Related Quality of Life among treatment-naïve patients with chronic hepatitis B. Utilizing the validated, localized Chronic Hepatitis B Quality of Life Scale (CHBQOL), the study assesses patients across four key dimensions-physical symptoms, emotional symptoms, beliefs, and social stigma-at baseline, 24 weeks, and 48 weeks post-treatment. By integrating PROs into clinical practice, the Hot wave Project goes beyond traditional biological endpoints to understand the challenges and benefits of HBV treatment from the patient's perspective, ultimately fostering a more patient-centered approach to chronic disease management.

| In-Hospital HBV Linkage-to-Care Cohort | This cohort consists of HBsAg-positive patients identified in non-hepatology and non-infectious disease departments across three participating medical centers from. An estimated 16,000 patients will be included in this prospective management cohort.Participants in this cohort are managed under the multidisciplinary "Hot wave Project 2.0" workflow. Positive HBsAg results are automatically captured by the hospital information system and flagged with cautionary remarks. Full-time project nurses proactively contact these patients via telephone, providing them with patient education materials, a quick medical consultation card, and encouraging them to visit the dedicated "Hepatitis B Health Clinic" within 2 weeks. |
| |
| Antiviral Therapy PRO Cohort | This cohort consists of adult (≥ 18 years), treatment-naïve patients with chronic hepatitis B enrolled from the "Hot wave Project 2.0" management cohort. Eligible patients must meet the indications for antiviral treatment according to the 2022 Chinese Guidelines for the Prevention and Treatment of Chronic Hepatitis B.Participants in this observational cohort will initiate standard-of-care antiviral therapy as prescribed by their physicians. Throughout the study, their Health-Related Quality of Life will be longitudinally assessed using the localized Chronic Hepatitis B Quality of Life Scale (CHBQOL). PRO assessments, alongside routine clinical parameters will be systematically collected at baseline (Week 0), and at 24 weeks and 48 weeks post-treatment. The target enrollment for this cohort is 300 participants. |

| Facilitate the referral of in-hospital chronic hepatitis B patients and provide treatment and follow-up in the infectious disease department. | Other | After visiting the hospital, high-risk HBV patients are prescribed HBsAg testing by their primary physician. If HBsAg positivity is detected in patients from non-infectious disease departments, their lab reports will include a reminder to visit the Hepatitis B Health Clinic. Some primary physicians may also request an infectious disease consultation or recommend patient referral. Additionally, within two weeks, the Hepatitis B Specialist Assistant will contact the patients by phone to provide referral recommendations. Once referred to the Hepatitis B Health Clinic, physicians will conduct health education, complete liver function and virological assessments, and develop individualized treatment and follow-up plans. |
| Measure | Description | Time Frame |
|---|---|---|
| Referral Rate | Referral rate of HBsAg-positive patients in non-infectious disease departments = Number of HBsAg-positive patients referred to infectious disease departments / Total number of HBsAg-positive patients in non-infectious disease departments. | 2 weeks |
| Changes in Health-Related Quality of Life assessed by the CHBQOL Scale | Patient-Reported Outcomes (PROs) and HRQoL are evaluated using the validated, localized Chronic Hepatitis B Quality of Life Scale (CHBQOL). The CHBQOL comprises 23 items categorized into four dimensions: physical symptoms, emotional symptoms, beliefs, and social stigma. This measure will calculate the longitudinal changes in both the total CHBQOL score and its dimension-specific sub-scores before and after initiating standard antiviral therapy. The objective is to quantify the impact of antiviral treatment on the quality of life in treatment-naïve CHB patients. | Baseline (Week 0), week 24, and week 48 |
| Measure | Description | Time Frame |
|---|---|---|
| Antiviral Treatment Rate | Antiviral treatment rate of HBsAg-positive patients in non-infectious disease departments = Number of patients from non-infectious disease departments starting antiviral treatment / Total number of HBsAg-positive patients in non-infectious disease departments. | 2 weeks |

| Assessment of patient-reported outcomes (PROs) in patients with chronic hepatitis B. | Other | Patients with chronic hepatitis B who meet treatment criteria and have not previously received treatment will undergo a routine clinical evaluation in a private setting under the guidance of trained staff and complete the Chronic Hepatitis B Quality of Life (CHBQOL) questionnaire prior to initiating standard antiviral therapy (baseline, Week 0). Subsequently, patients will return for scheduled follow-up visits at Weeks 24 and 48 after treatment initiation. During follow-up visits, physicians will assess liver function and virological suppression. Additionally, the CHBQOL questionnaire will be administered again to evaluate changes in patients' health-related quality of life over time, as well as to monitor medication adherence and adverse events. |

This measure evaluates the long-term cost-effectiveness and cost-utility of the "Hot wave" in-hospital management strategy. Real-world data collected from this study-specifically the observed HBV linkage-to-care and treatment initiation rates-will be integrated into a validated decision-analytic Markov model. The model will be parameterized with localized epidemiological and demographic data from Guangzhou . By simulating different policy scenarios over a lifetime horizon, the model will predict cumulative costs and health outcomes, including Quality-Adjusted Life Years (QALYs) and the number of averted HBV-related complications . The final outcome will be expressed as the Incremental Cost-Effectiveness Ratio, representing the cost per additional QALY gained compared to the status quo. |

| Correlation Between HRQoL Changes and Clinical Responses | To evaluate the relationship between the longitudinal changes in CHBQOL scores (Patient-Reported Outcomes) and key clinical efficacy indicators. Specifically, this measure will analyze how achieving virological suppression (undetectable HBV DNA) and biochemical response (ALT normalization) correlates with improvements or declines in patients' Health-Related Quality of Life during the antiviral treatment period. | Baseline (Week 0), Week 24, and Week 48 |
| Predictive Factors Affecting HRQoL Changes | To analyze the sociodemographic and clinical factors that significantly influence the trajectory of PRO changes in CHB patients undergoing antiviral therapy. Evaluated factors will include, but are not limited to, patient age, gender, baseline liver fibrosis stage (assessed via FibroScan scores or imaging), and the presence of comorbidities. This analysis aims to identify specific patient subgroups that may require additional clinical attention or distinct management strategies to improve their quality of life. | Baseline (Week 0), Week 24, and Week 48 |
