CMED6200 Introduction to epidemiology Coordinator: Dr Ryan Au Yeung Credit Units: 3 Pre-requisite: No This course introduces the basic concepts and approaches used in epidemiologic research, and serves as a prerequisite for several other courses. The course begins with an introduction to common approaches to measure the occurrence and distribution of illness in populations and the relationship between different measures. The course then moves on to introduce the major types of epidemiological study designs. Students will learn to design, interpret and critically appraise each type of study, with the aim of differentiating between the study designs and appreciating their relative strengths and limitations in identifying the determinants and causes of illness and disease. The concept of causal inference will be introduced with focus on common pitfalls in epidemiological studies that could lead to biased estimation of the causal relationship. Finally practical issues in designing and implementing epidemiological studies will be discussed, and students will learn to use appropriate terminology and language to report epidemiological findings. Throughout the course, major historical and contemporary epidemiological studies will be described. Close

CMED6040 Advanced statistical methods II Coordinator: Dr Tim Tsang Credit Units: 3 Pre-requisite: (i) CMED6100 Introduction to biostatistics and (ii) CMED6020 Advanced statistical methods I This course will provide a basic, yet thorough introduction to probability theory and mathematical statistics that underlie many of the commonly used techniques in public health research. The frequentist and Bayesian approaches to parameter estimation, interval estimation and hypothesis testing will be compared and contrasted. All theoretical material will be motivated by problems from epidemiology and public health. Close

CMED6208 Risk: perception, decisions and communication Coordinator: Dr J Liao / Prof R Fielding Credit Units: 3 Pre-requisite: No Risk is inevitable in life, yet the ability to accurately judge risk and the decisions made thereafter are usually quite skewed by psychological, social and contextual factors, so much so that serious errors can occur in decision making. In healthcare, the ability to accurately assess risk and the psychological strategies that people adopt to avoid the threat that risk presents means that health hazards are often completely misrepresented both to ones self and to others. Health professionals also have the task of communicating health risk information to the community as well as individuals. How can information be presented in such a way as to effectively communicate the true nature of a hazard without distorting or falling into the trap of being ignored? This course looks in detail at the area of risk perceptions, the distortions of decisions by psychological and other factors and the communication of risk, all core skills for public health professionals.

CMED6105 Infectious diseases in public health Coordinator: Prof LLM Poon Credit Units: 3 Pre-requisite: No Infectious diseases are of major public health concern. This course focuses on the study of common human infectious diseases from a public health point of view. The course covers basic microbiology, common infectious diseases in community and health care settings, and provides the biological basis for the methods used for prevention and control of communicable diseases. This course has a strong emphasis on the practical aspects of infectious disease and is important to those who are working or pursue their career in the fields of epidemiological investigations, public health surveillance, and other public health responses that are related to microbial infections.

CMED6203 Measurement in health Coordinator: Dr M Ni Credit Units: 3 Pre-requisite: No The majority of public health and clinical research involves surveying patients or the public and measuring aspects of health status. This course provides students to an introduction to survey research methods, including sampling approaches, the design of questionnaires, selection of data collection modalities, and evaluation of psychometric properties of measurement scales. ​ The course will also cover reliability and validity analyses of an existing health measurement instrument, and the process of developing an instrument where a suitable one does not already exist are considered. The utility of a number of screening tools, clinician rating scales and self-report health indicators among others are critically evaluated. The course project will also provide an opportunity to design and develop your own survey questionnaire. Close

3 CMED6900 Health policy and politics Coordinator: Dr K Grepin Credit Units: 3 Pre-requisite: No This course begins by introducing the core macroeconomic and political theories needed to understand and assess national or regional health systems. Based on these theoretical considerations and empirical observations from the field, students are led through a survey of system typologies from around the world. The concept of "control knobs" is then deployed to translate theoretical appreciation into real world application. Finally students are given the opportunity to undertake a self-directed simulation exercise on a prevailing policy topic in the Hong Kong or mainland Chinese setting. Close

3 CMED6401 Advanced clinical epidemiology and decision analysis Coordinator: Dr IOL Wong Credit Units: 3 Pre-requisite: (i) CMED6200 Introduction to epidemiology and (ii) CMED6100 Introduction to biostatistics This is an intermediate/advanced-level course on methods of clinical epidemiology and decision science. It covers the techniques and growing range of applications of decision analysis and cost effectiveness analysis in healthcare technology assessment, health policy analysis, medical decision making, and health resource allocation. Students will learn to apply methods that are currently used at the frontiers of clinical epidemiology and decision science research in clinical and public health settings. While the primary emphasis is not mathematical theory, a certain amount of theoretical background is presented for each topic. Close

CMED6030 Advanced epidemiological methods I Coordinator: Dr Jane Zhao Credit Units: 3 Pre-requisite: (i) CMED6200 Introduction to epidemiology and (ii) CMED6300 Intermediate Epidemiology The overarching conceptual framework for this course centres on the use of structural causal models to design, analyze and interpret study design commonly used in epidemiology, including observational, instrumental variable, quasi-experimental and experimental study designs. This course will consider how structural causal models, mediation analysis, effect modification, , sensitivity analysis and consideration of missing data, can be applied to the pursuit of making valid and transportable causal inferences in epidemiology. Close

CMED6107 Advanced immunology Coordinator: Credit Units: 3 Pre-requisite: A Bachelor of Science degree in biology or immunology or equivalent. Prior approval of the HKU-Pasteur Research Pole. Each year, this course will focus on a different topic, including innate immunity, inflammation, mucosal immunity, vaccination, and or adaptive immunity. Special emphasis is placed on diseases that represent a threat to public health in this region. Lectures are given by internationally renowned scientists, workshops/round tables are supervised by junior faculty members, and practical sessions organized together with local and/or invited faculty members.
