Overview

This is a foundational health unit addressing the essential epidemiological skills and principles that health professionals need to develop for effective public health and clinical practice. Epidemiology can assist in determining risk factors associated with diseases and what factors may protect against disease. Epidemiology also identifies the effectiveness of health interventions and quantifies potential harms. The skills of scientific assessment of the effectiveness of prevention strategies are necessary for service provision and policy development. In this unit, you will develop the ability to critically evaluate research and study designs using epidemiological techniques in structured peer discussion. This introductory unit develops the skills in effectively assessing and interpreting health data and the medical literature. The unit explains how to calculate key measures of disease occurrence and association and contemporary issues of major importance in health. 

Learning Outcomes

On successful completion of this unit you will be able to:

  1. Critically evaluate epidemiological methods and designs and develop collaborative skills through peer learning
  2. Develop skills to accurately calculate and interprete of measures of the occurrence of disease and association between exposure and disease in the case-examples provided;
  3. Apply epidemiological concepts and methods to the critical analysis of health problems;
  4. Describe the knowledge of the nature of causal inference within the framework of contemporary epidemiology;
  5. Apply knowledge of strategies for disease screening, surveillance, outbreak investigation and other control methods as a public health response.

Content

  • The application of epidemiology and quantitative research methods in population and clinical health sciences
  • Measurement of exposure and risk of disease
  • Design of epidemiology studies
  • Causality and association
  • Methods of disease surveillance in the community
  • Understanding and identifying risks of bias in epidemiological studies
  • Epidemiological principles for health program evaluation.

Learning Approaches

The integration of theory and practice is achieved by linking lectures and tutorial discussions. Teaching methods include live-streamed on-campus lectures and tutorials offered on-campus and online using relevant digital technology, literature searches and self-directed learning. You will have the opportunity to participate in tutorials either on campus using the collaborative spaces (enrolled internally) or the same content reformated for the online environment (online enrolment).  Learning to collaborate with professionals locally and remotely is an important skill for epidemiologists, researchers and other health professionals. In this unit, all students are required to participate in peer review with a discussion partner and reflect on learnings from this process.

Feedback on Learning and Assessment

You will receive formative feedback through your use of audience response technology to undertake interactive in-class polling to provide an assessment of your knowledge during the lecture and provide immediate feedback on the effect of teaching to your lecturer. You will formally engage in Peer Discussion with another student, providing and receiving feedback on your independent work within the construction of the pedagogy of peer-learning. Feedback will also be available from the teaching staff after completing the formative assessments. The peer-learning practised in lectures, and tutorials will develop skills for the second assessment.

Assessment

Overview

There are three assessment pieces overall and these include both formative and summative items. The first is an invigilated examination to test your knowledge of epidemiological concepts and skills in calculation and interpretation of measures. Lectures and tutorial discussions will assist in working toward this assessment task. In the second assessment, you will be asked to first work independently and then to work with a peer on the development and conceptualisation of an analytical report. To maximise engagement with the task, you will work on crafting independently with the template provided, a substantial draft that is the basis of your discussion with a peer and uploads it in Week 10; then the revised report is submitted in Week 12. Tutorial activities will guide and inform the second piece of assessment. You will be required to describe the feedback provided and received and any resulting actions. The final item is a timed problem-solving task in Week 13. Each assessment item is designed to measure your ability to apply the knowledge and skills stated in the unit learning outcomes. Embedded support for learning is the peer and tutor feedback on drafts and tasks applied to support you in completing assessment pieces.

Assessment Tasks

Assessment: Exam

This assessment contains both multiple choice and short answer questions to test your knowledge and ability to calculate and interpret the measures of the occurrence of disease and measures of association between exposure and disease; application of specialised knowledge of the principles and methods underlying epidemiological study and strategies for disease prevention, disease surveillance and outbreak investigation. Your ability to distinguish causality from simple association and your advanced understanding of the nature of causal inference will also be assessed. This is an invigilated exam. 

Weight: 40
Length: 1:50 hours
Individual/Group: Individual
Due (indicative): Week 7
Related Unit learning outcomes: 2, 4

Assessment: Analytical Report

The report simulates interdisciplinary and interprofessional practice in a government health agency where you are required to apply an appraisal tool to critically evaluate and synthesise an epidemiological study and then submit an analytical report detailing your response. You will be provided with a personalised template representative of a standard government and industry procedure to prepare and submit the report. 

The authentic role is a professional in a government health agency working with other disciplines. The audience are peer students and a government health agency. The purpose is to show your ability to work interprofessionally in critiquing evidence-based literature and negotiating responses. The product is the analytical report. Embedded support for learning is the peer and tutor feedback on drafts and support to complete this task.

Process

You will be given a published research study to analyse and critique as well as a critical appraisal tool and guide. You will choose a partner to simulate the real-world discussion and negotiation and share your well-developed drafts to discuss concepts and principles.

The assessment requires the application of the appropriate epidemiological principles and negotiation skills to assess the trustworthiness (risks of bias) of published research of a public health intervention using standard critical appraisal tool methodology. 

You will sign up in Canvas with another student you have chosen to be your discussion partner.

Both you and your partner undertake the critical analysis individually and then upload your own drafts into Canvas. Following the upload, you will then engage in a discussion using the structure of the assessment as your guide. Skills in peer discussion will be taught in lectures and tutorials, supported by written documentation in the assessment guide. It is a requirement of this assessment to engage in peer feedback.

Following the discussion, you have the opportunity to collaborate together and submit jointly or submit individually.

This is an assignment for the purposes of an extension. 

Weight: 50
Length: 3000 words
Individual/Group: Either group or individual
Due (indicative): Week 12
You will submit a substantial draft that you will use to discuss with your partner, at a date around Week 10. Only final submissions that have a draft uploaded will be graded. Peer feedback is mandatory to receive a result for this assessment task.

Academic Integrity

Students are expected to engage in learning and assessment at QUT with honesty, transparency and fairness. Maintaining academic integrity means upholding these principles and demonstrating valuable professional capabilities based on ethical foundations.

Failure to maintain academic integrity can take many forms. It includes cheating in examinations, plagiarism, self-plagiarism, collusion, and submitting an assessment item completed by another person (e.g. contract cheating). It can also include providing your assessment to another entity, such as to a person or website.

You are encouraged to make use of QUT’s learning support services, resources and tools to assure the academic integrity of your assessment. This includes the use of text matching software that may be available to assist with self-assessing your academic integrity as part of the assessment submission process.

Further details of QUT’s approach to academic integrity are outlined in the Academic integrity policy and the Student Code of Conduct. Breaching QUT’s Academic integrity policy is regarded as student misconduct and can lead to the imposition of penalties ranging from a grade reduction to exclusion from QUT.
