2019 Data linkage webinar series

Data linkage is the bringing together of records from different data collections related to the same individual. It can be useful in the context of clinical trials in a number of ways, including:
  • A less burdensome method of data collection for participants during a clinical trial
  • Cost-effective medium to long term follow-up of clinical trial participants
  • Measurement of healthcare use before and after an intervention to assist in effectiveness and health economic analysis
  • Post-market surveillance of therapeutics
Australia has a national data linkage network, the Population Health Research Network (PHRN) that enables existing health data from around the nation to be brought together and made available for research purposes. To date, the PHRN infrastructure has been infrequently used by clinical trials researchers. ACTA and the PHRN have developed this series of webinars to:
  • Introduce clinical trial researchers to the PHRN facilities and services available
  • Demonstrate the benefits of using linked data in clinical trials research
  • Assist clinical trial researchers to design clinical trials using linked data and apply for access to linked data
We gratefully acknowledge support from the Australian Research Data Commons (ARDC) in delivering this project to you. This series consists of four sessions. The webinar content is outlined below. PHRN Data Linkage 1: Designing Clinical Trials using Linked Data Wednesday 20 March⋅1:00 – 2:00pm AEDT Recording now available Dr Felicity Flack  Objectives: By the end of this webinar participants should be able to:
  • Name examples of administrative data collections available for linkage to clinical trials cohorts
  • Identify the benefits and limitations of using linked administrative data in clinical trials
  • Describe the main factors to take into account when designing a clinical trial using linked administrative data
Webinar Content: What is administrative data? Examples of administrative data available for linkage in Australia What are the benefits of using linked administrative data in clinical trials? Examples of what linked administrative data (Australian & international) can be used for e.g.
  • Long term follow-up (all participants or only those lost to follow-up)
  • Pre-recruitment hospitalisation as a measure of trajectory to care
  • Measurement of healthcare use before and after an intervention
  • Identification of eligible individuals or communities
  • Economic analysis
  • Aboriginal and Torres Strait Islander status
What are the limitations of using linked administrative data in clinical trials?
  • Limited data items
  • Limited data quality/validity information
  • Limited metadata
  • Linkage quality
Key points to consider when designing a clinical trial:
  • Is the administrative data fit for purpose?
  • What skills/experience will the research team require to analyse administrative data?
  • Have the participants provided informed consent or are there grounds to apply for a waiver of consent?
  • How will the data be cleaned, managed and kept secure?
Resources available
  • Metadata
  • Training courses
  • Publications
