Overview
This unit explores the importance and role of epidemiology as an approach to both public health and clinical practice. You will be able to use evidence from epidemiological investigations, to understand the distribution of health outcomes in populations and understand the influence of factors that determine this distribution. The critical function of epidemiology will be reviewed including areas of anticipated needs, identified risk conditions, definition of priorities and the use of available resources for planning and administering health care services.

Feedback, Recommendations and Responses
Every unit is reviewed for enhancement each year. At the most recent review, the following staff and student feedback items were identified and recommendations were made.
Feedback from Personal reflection and discussion with Head of Course and Academic Lead (Learning & Teaching) for the School
Revision of alignment of learning outcomes and weighting of assessments.
The alignment of the learning outcomes and weighting of assessment items means that it is possible for students to pass the unit without displaying mastery of some fundamental concepts. This was discussed at length with the Head of Course and the Academic Lead (Learning & Teaching) within the School. A revision of the alignment and weighting of the assessment items will be undertaken and a Unit Change Proposal submitted to take effect from Term 1 2021.
- Calculate and communicate epidemiological statistics relating to the measurement of health, wellness and disease.
- Interpret epidemiological data within theories and frameworks of social justice and cultural diversity for effective knowledge transfer and exchange.
- Evaluate epidemiological investigations and sources of epidemiological data to identify inequities, enable change and advocate for health.
- Argue for a population health outcome using relevant research methods and approaches.
- Explain principles of data confidentiality and disclosure, and apply the ethical use of data.

1 Presentation
In this assessment you will research, create, and record a 10 minute oral presentation that describes the population health impact for one of the following health issues for the Australian population.
In your professional life, you will apply your knowledge of epidemiology to describe the impact of health outcomes, the patterns of disease, or the risks of a particular outcome in your work with clients, collaborators, or to the general public. This assessment is a practical application of that.
You are to research, create, and record a presentation (using Zoom) that describes the population health impact for one of the following health issues for the Australian population. You will need to source, interpret and communicate the current epidemiological evidence using appropriate measures. Your presentation will need to be recorded and uploaded to the Moodle site as well as a copy of your slides and notes by 9am Monday, of week 6.
Your presentation needs to include:
- A clear introduction to the health issue that provides a clear definition and justification of why it is important.
- The use of a range of appropriate epidemiological measures to critically demonstrate the impact this health issue has on:
- the Australian population as a whole, and
- within or between different population groups of relevance (differential impact). For example: age, gender, geographic location, occupation
- The use of data visualisation that contributes to the effective communication of the issue.
- A clear and concise conclusion that links to the introduction and the contents of the presentation.

2 Group Discussion
Tutorials allow students to develop and practice their skills in applying epidemiological and population health concepts consistent with how they will as health professionals. It fosters the development of oral and written skills, as well as group skills such as interaction and cooperation in a multi-disciplinary environment. It allows students the opportunity to reflect on issues and applications of concepts from other learning resources and demonstrate their understanding in their interactions and submitted work. Student also have the opportunity to develop respect and consideration for other's points of view as well as the capacity to critique responses from their peers in a collegial and supportive environment.
Each week students will have the opportunity to discuss and then complete a series of structured tutorial tasks applying the epidemiological concepts and study designs learnt that week. A Zoom drop-in session will be held each week from week 2 for those students who prefer oral discussion. Students who cannot attend the tutorial or prefer written discussion will have a forum for peer discussion and guidance in completing the activities. Students will submit five of the activities from throughout the term for assessment. Three of these will be compulsory and two can be chosen by the student. Two activities from weeks 1 to 5 will be submitted for assessment on Friday in week 6 and the other three will be submitted for summative assessment by 9am Monday Week 12. These will be worth 10% and 15% of the overall mark respectively.
Two activities from weeks 1 to 5 will be submitted for assessment by 9am on Friday of Week 6 and the other three will be submitted for assessment by 9am Monday of Week 12.

3 Written Assessment
In this assessment you will research and write an application for funding to support an evidence based intervention to improve population level health in relation to the issue you critically outlined in assessment 1 (presentation).
In your professional life, you may apply your knowledge of epidemiology to support applications for funding by your employer, either through grants or budget requests, to address health outcomes within your area. This assessment is a practical application of that scenario.
The organisation you work for is applying for a grant to address the health outcome you examined in assessment 1. You are to complete an application requesting funding to conduct an evidence based population level intervention to improve public health in relation to your topic. The application requires you to use an evaluation of relevant literature to propose an appropriate evidence based, contextually relevant approach that addresses the health issue. This is consistent with the goal of public health to ask not just "what works" but to address "what works for whom, under what circumstances, and how".
The funding body has provided a template for the application with prescribed sections and word limits to explain your proposed project.
You are to research and identify evidence based approaches to address the health outcome of interest that are suitable for the context you are implementing it in. You will need to source, interpret and communicate the current epidemiological evidence demonstrating your understanding of the different study types and how they support your claims. Your completed template, including your references, will need to be uploaded to the Moodle site.
Exam Week Friday (19 Feb 2021) 9:00 am AEST
Assessments will be returned to students 2 weeks after the due date.

As a CQUniversity student you are expected to act honestly in all aspects of your academic work.
Any assessable work undertaken or submitted for review or assessment must be your own work. Assessable work is any type of work you do to meet the assessment requirements in the unit, including draft work submitted for review and feedback and final work to be assessed.
When you use the ideas, words or data of others in your assessment, you must thoroughly and clearly acknowledge the source of this information by using the correct referencing style for your unit. Using others’ work without proper acknowledgement may be considered a form of intellectual dishonesty.
Participating honestly, respectfully, responsibly, and fairly in your university study ensures the CQUniversity qualification you earn will be valued as a true indication of your individual academic achievement and will continue to receive the respect and recognition it deserves.
As a student, you are responsible for reading and following CQUniversity’s policies, including the Student Academic Integrity Policy and Procedure. This policy sets out CQUniversity’s expectations of you to act with integrity, examples of academic integrity breaches to avoid, the processes used to address alleged breaches of academic integrity, and potential penalties.
What is a breach of academic integrity?
A breach of academic integrity includes but is not limited to plagiarism, self-plagiarism, collusion, cheating, contract cheating, and academic misconduct. The Student Academic Integrity Policy and Procedure defines what these terms mean and gives examples.
Why is academic integrity important?
A breach of academic integrity may result in one or more penalties, including suspension or even expulsion from the University. It can also have negative implications for student visas and future enrolment at CQUniversity or elsewhere. Students who engage in contract cheating also risk being blackmailed by contract cheating services.
Where can I get assistance?
For academic advice and guidance, the Academic Learning Centre (ALC) can support you in becoming confident in completing assessments with integrity and of high standard.
