Yan Zhuang’s presentation examines the real-world quality of asthma care in Chinese primary healthcare settings using unannounced standardized patient visits across seven provinces. The study evaluates care across five dimensions: effectiveness, safety, patient-centeredness, timeliness, and efficiency. The findings show suboptimal performance in history-taking, physical examination, diagnosis, and treatment, with an overall correct diagnosis rate of 47.1%. Care quality varied substantially by region, institution type, and clinician characteristics. These findings highlight the need to strengthen primary care capacity, improve standardized asthma diagnosis and treatment, and reduce inequalities in care quality across settings in China.

Senior citizens are at a higher risk of contracting vaccine-preventable diseases (VPDs) due to age-related changes in their immune systems and increased exposure to infectious agents. Vaccinations can help the elderly reduce the risk of VPDs, as well as complications, hospitalizations, and death. Globally, the vaccination rate among rural elderly populations is generally lower than that in urban areas. The present study aims to explore and understand the practices and perceptions of Chinese elderly in rural areas towards vaccination in the context of COVID-19. Four graduate students from the School of Health Services Management, at Anhui Medical University (AMU), recruited a total of 13 older adults aged 60 years or older from their hometown villages and conducted two rounds of in-depth qualitative interviews. The focus was on influenza, pneumococcal, and COVID-19 vaccines, particularly in the context of the COVID-19 pandemic. To avoid being constrained by a purely public health theoretical framework, the qualitative interviews incorporated a sociological perspective. Qualitative data were analyzed using grounded theory and an attempt was made to construct the conceptual frameworks.

Nearly 30000 people fall ill and over 4000 die of tuberculosis (TB) every day (UNAIDS factsheet). A quarter of the world population are latently infected with TB making a large reservoir of people at risk of developing active (symptomatic) TB disease. Treatment is long, taking a minimum of six months for drug susceptible TB and 9 months for drug resistant TB, yet standard-of-care treatment monitoring tools are ineffective. Taking advantage of abundant ribosomal RNA in the bacterial cell, we developed the tuberculosis Molecular Bacterial Load Assay (TB-MBLA) test which detects and quantifies live TB bacteria in patient specimens giving a result in 4h. The live TB bacillary load count of patients responding positively to therapy declines over the course of treatment and can be detected as early as 3 days from initiation of treatment. Using TB-MBLA we have shown that a good proportion of TB patients clear sputum bacillary load to zero by week 2 and remain negative throughout 6 months of treatment, increasing hopes of personalised- and shorter- treatment regimens.  We applied the same assay to cattle specimens and found over 40% had live TB in their livers and lungs just before the meat was sold off for food in Nigeria. This means control of human TB may not succeed without control of TB in animals. Apart from active TB, we have exploited the idea of human genes that are expressed specifically in response to TB infection to develop a diagnostic that distinguishes latently infected from healthy individuals. Clinical evaluation in Malawi has shown our diagnostic is more sensitive than the standard-of-care interferon gamma release assay (IGRA). We believe our latent TB diagnostic will provide an efficient tool to guide appropriate administration of TB preventive therapy globally.

The study investigated the determinants affecting inpatient satisfaction in a US-based post-acute care rehabilitation hospital, focusing on how various hospital service domains influence patient satisfaction, the overall quality of care, and patients’ willingness to recommend the hospital. It utilized patient-level data from electronic medical records and Press Ganey satisfaction data, analyzing responses from 4,785 patients. The research found that personal issues domain was the most significant factor affecting patient satisfaction, followed by domains related to physical therapy, nursing, discharge, and food services. This study provides insights into improving patient experience by prioritizing areas needing enhancement, especially in communication and service delivery within rehabilitation settings.

The potential of digital health interventions to address the burden of unhealthy lifestyles has been hindered by low user engagement. In this seminar, Dr Luk will introduce a chat-based intervention model that leverages mobile instant messaging to overcome some engagement barriers. He will share his research journey in developing and evaluating the model for promoting smoking cessation. Dr Luk will also discuss his recent efforts in implementing and adapting the chat-based approach to address other health behaviours.
