Data Extraction and Analysis (Pen) Tools

General practices in western Victoria can access a suite of data extraction and analysis tools to improve service planning, reporting and population health monitoring. On behalf of our region’s practices, Western Victoria PHN (WVPHN) has acquired licences for the Pen Computer Systems (Pen CS) suite of CATPlus data tools.

Using Pen tools in general practice

WVPHN provides the Pen CS tools so general practices can meet data submission requirements for Practice Incentive Payment – Quality Improvement (PIP QI) accreditation.

However, the tools provider a broader range of benefits to general practices looking to improve data quality and ensuring patient records are accurate and up to date.

Practices can also use the Pen tools to help target patients with specific needs of health risk profiles, namely in chronic disease management, cancer screening, immunisations, medication reviews, sexual health, ehealth and preventative health.

To access the tools, general practices must sign the Western Victoria Data Extraction Tool Agreement.


CATPlus is a comprehensive data extraction tool containing three interfaces:

  • CAT4 – for management of practice-wide data
  • TopBar – for management of individual patient data
  • PAT CAT – used by WVPHN to compile and manage de-identified and aggregated data from contributing general practices.

For more information on the CAT4 and TopBar tools, visit the CATPlus Tools for General Practice page.


WVPHN uses PAT CAT as part of our region-wide population health monitoring and planning.

The tool brings together the de-identified data submitted from multiple general practices which can then be used to generate graphs, charts and reports.

This information is essential for WVPHN to meet requirements set out by the Federal Government to improve the delivery of primary health care services in our priority health areas, namely:

  • Mental health
  • Aboriginal and Torres Strait Islander health
  • Population health
  • Health workforce
  • Digital health
  • Aged care
  • Alcohol and other drugs treatment.

Please note: data submitted to us does not include any identifying details of individual patients.
