PUBH5215: Analysis of Linked Health Data

Intensive June, 2024 [Online] - Camperdown/Darlington, Sydney

Throughout our lives, information about our health and the care we receive is recorded and stored across various health-related databases, e.g., hospital admissions, ambulance service, cancer registry. Data linkage is a process that brings together information from different databases about the same individual, family, place or event. This process creates a chronological sequence of health events or individual 'health story' that can be combined into a much larger story about the health of people. This information can be used for research or to improve health services. This unit is suitable for health services researchers, policy makers, clinical practitioners, biostatisticians and data managers. We explain how data linkage is conducted, illustrate how data linkage can be used for research, highlighting the advantages, and the dangers and pitfalls. We describe how to design linked data studies, outline the data management steps required before analysing the data, and discuss some of the methods and issues of analysing linked data. Students will have access to data from a real data linkage and will gain hands-on experience to develop their programming skills for handling large complex dataset

Assessment summary

  • Students will complete a small (up to 5 multiple choice question) time-limited quiz for each of Modules 1 to 4, covering theoretical concepts. Each module quiz will be worth 5%, for a cumulative total of 20%.  
  • The recorded presentation will require students to prepare and record a short presentation (along with the slide deck) for submission on a specified conceptual topic.
  • The analysis report will require students to perform a data analysis using linked data and report on their findings, including providing the relevant statistical code used to generate the responses. 

Detailed information for each assessment will be provided on Canvas.

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Grade

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

  • Deduction of 5% of the maximum mark for each calendar day after the due date.
  • After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website  provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.  

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Support for students

The Support for Students Policy 2023 reflects the University’s commitment to supporting students in their academic journey and making the University safe for students. It is important that you read and understand this policy so that you are familiar with the range of support services available to you and understand how to engage with them.

The University uses email as its primary source of communication with students who need support under the Support for Students Policy 2023. Make sure you check your University email regularly and respond to any communications received from the University.

Learning resources and detailed information about weekly assessment and learning activities can be accessed via Canvas. It is essential that you visit your unit of study Canvas site to ensure you are up to date with all of your tasks.

If you are having difficulties completing your studies, or are feeling unsure about your progress, we are here to help. You can access the support services offered by the University at any time:

Attendance and class requirements

Enrolled students are expected to attend all live sessions, either in-person or online, unless prior arrangements have been made with the unit of study coordinator. 

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Learning outcomes are what students know, understand and are able to do on completion of a unit of study. They are aligned with the University's graduate qualities and are assessed as part of the curriculum.

At the completion of this unit, you should be able to:

  • LO1. understand the theory of data linkage methods and features of comprehensive data linkage systems, sufficient to know the sources and limitations of linked health data sets
  • LO2. apply epidemiological principles to the design of studies using linked data
  • LO3. construct numerators and denominators for the analysis of disease trends and health care utilisation and outcomes
  • LO4. assess the accuracy and reliability of data sources
  • LO5. check data linkages and assure the quality of the study process, e.g. consistency of definitions, missing data
  • LO6. list the issues to be considered when analysing large linked data files
  • LO7. write syntax to prepare linked data files for analysis, derive exposure and outcome variables, relate numerators and denominators, and produce results from statistical procedures.

Graduate qualities

The graduate qualities are the qualities and skills that all University of Sydney graduates must demonstrate on successful completion of an award course. As a future Sydney graduate, the set of qualities have been designed to equip you for the contemporary world.

This section outlines changes made to this unit following staff and student reviews.

This course was last delivered in block mode in June 2023. In response to student feedback, the assessment tasks have been restructured allowing for a more balanced assessment between theoretical concepts and practical skills, along with opportunity for some earlier feedback on conceptual understanding prior to completing the final major assessment. A selection of previously recorded lectures will be delivered live, or re-recorded for this delivery.
  • Access to either R or SAS (installed locally, or via remote access), and a stable internet connection, is required to complete this unit of study.
  • Offsite students will be required to connect to the university virtual private network (VPN) to access data sets for use in practical sessions.
  • Before gaining access to learning resources, students will be required to agree to a confidentiality agreement
  • It is prohibited to copy and locally store the data sets used in this unit of study.

Further information will be provided on Canvas.
