PROBE study

PROBE logoHow can HFA and haemophilia organisations around the world have access to good quality data about the treatment and health experiences of people with bleeding disorders?

The multi-national PROBE (Patient Reported Outcomes Burdens and Experiences) Study aims to do precisely that.

Haemophilia Foundation Australia has joined the PROBE investigation team to be part of this important international study on the impact of living with a bleeding disorder.

WHAT IS THE PROBE STUDY?

PROBE is a patient-focused research project led by a global team of patient and academic investigators, including Mark Skinner, former WFH President, and Assoc Prof Alfonso Iorio from McMaster University, Canada, who have worked closely with HFA on the Australian arm of the study. The research will support efforts to improve treatment and comprehensive care programs in Australia and other countries around the world.

In the future the PROBE study will cover the range of bleeding disorders. The initial stages of the survey (Phases 1 and 2) are testing the research methodology in haemophilia and allow people with haemophilia to report their haemophilia severity, treatment history and the impact of haemophilia on their daily life.

This data will be used to analyse the perspectives of people with haemophilia on outcomes that affect their own life and care. It is particularly important data to have when HFA tries to understand what the issues are for our community, and will enable us to quantify and represent these issues in a robust and credible way to our Council and others, such as governments or treatment and service funding bodies.

About the PROBE study

Haemophilia Foundation Australia is participating in the PROBE (Patient Reported Outcomes Burdens and Experiences) Study.

The PROBE study is a multi-national, patient-focused research study.

The PROBE study allows people with haemophilia to report their haemophilia severity, treatment history and the impact of haemophilia on their daily life. This data will be used to analyse the perspectives of people with haemophilia on outcomes that affect their own life and care. The research will support efforts to improve treatment and comprehensive care programs in Australia and other countries around the world. All data will be kept confidential.

PHASE 1

Phase 1 (2014-2015) was the very first stage of developing the questionnaire:

  • Test understanding of questionnaire content and clarity (haemophilia impact only at this stage)
  • Assess methodology and in-country implementation feasibility
  • Establish core analytics​

A small number of Australian community members with haemophilia or parents of children with haemophilia were invited to test the draft questionnaire and give feedback on the questions and instructions.

PHASE 2

Phase 2 (2016) is the next stage to assess the questionnaire's feasibility through a pilot study:

  • Validate proof of concept
  • Pilot web platform
  • Assess reproducibility
  • Establish analytic controls/population comparators

PHASE 3

Phase 3 (2017-beyond) is the final stage of implementing the study around the world:

  • Real world roll-out
  • Complement and enhance the utility of national registries or WFH Global Survey data
  • Measure impact of country development initiatives.

Who is Probe?

PROBE is a multi-national patient-focused investigator driven research project. It is led by a global team of patient and academic investigators with diverse professional credentials:

AUSTRALIAN INVESTIGATION TEAM:

Haemophilia Foundation Australia
Suzanne O’Callaghan, Policy Research and Education Manager - Leading research study implementation in Australia
Monash University, Melbourne
Dr Liz Bishop, Michael Kirby Centre for Public Health and Human Rights - Overseeing ethical process; answering any ethics concerns or queries

Mark Skinner and Alfonso Iorio's PROBE Team at McMaster University in Canada are leading the international PROBE investigation with the Australian team.

PRIVACY

The PROBE study is voluntary and anonymous and surveys are treated confidentially. In Australia, people participating must return their print surveys in reply paid envelopes to HFA to ensure they are not identifiable. They are then uploaded securely for the international PROBE team data manager to analyze. Alternatively, if they complete their survey online, their survey results will go directly into to the secure PROBE survey database, auspiced by McMaster University, Canada. Only the PROBE teams at HFA and McMaster University will see the original print surveys and all original print surveys will be kept in locked and password protected secure storage at HFA and McMaster University. All survey data will be kept confidential and no data will be reported that could identify individuals.

The PROBE study has Human Research Ethics Approval from Monash University (MUHREC Project Number: CF15/4363 - 2015001518).

If you have any questions about the ethical process of this study, please contact:

Dr Liz Bishop. Monash University - liz.bishop@monash.edu 

If you have any concerns or complaints about the conduct of the project, please contact the Executive Officer, Monash University Human Research Ethics (MUHREC): muhrec@monash.edu

HFA PARTICIPATED IN PHASE 1 OF THE PROBE STUDY

Some of you were involved in distributing and completing the surveys for Phase 1. Thank you for your support! We needed 35-50 completed surveys by the end of 2015 to have enough data to be analysed, and by Christmas had received 39 surveys, which was an amazing effort in a very short few weeks!

WHAT DID PHASE 1 INVOLVE?
  • Seeking ethics approval via Monash University, Melbourne
  • Testing how clear the questions are
  • Testing the methodology and the statistics that could be gained from the results.

Our thanks to Dr Liz Bishop from the Michael Kirby Centre for Public Health and Human Rights at Monash University for her support of the ethics process.

Phase 1 tested a print survey on haemophilia only. Some Australian community members with haemophilia and carers or parents of children with haemophilia completed the draft questionnaire and gave feedback on the questions and instructions. The completed surveys and question feedback sheets were then scanned and transferred electronically to the PROBE research team at McMaster University for analysis.

RESULTS

HFA received a report on the Australian results in January 2016 and was invited to participate in an international meeting where the worldwide results were discussed:

  • More than 700 surveys were completed by 15 countries
  • Results demonstrated validity and that the research methodology was robust
  • Phase 1 data is useful for understanding how to use the potential results but cannot be used for representation on health issues at this point – we need to wait for phase 3
  • Australian feedback on questions was put in a spreadsheet and each comment was addressed by the research team leaders
  • As a result of global feedback, new questions will be added in Phase 2 for women who carry the gene
  • Some other small changes were made to the Australian version of the survey
  • For good comparable data, in future Australia needs to recruit more people with moderate haemophilia to complete the survey.

A poster about Phase 1 was presented at the European Association for Haemophilia and Allied Disorders (EAHAD) Congress in Sweden in February 2016 and very well received.

PHASE 2

The next phase involved reproducibility – testing an online version of the survey as well, and retesting the same community (ie, Australia) twice in several months to see whether the results remain consistent. This phase was completed in February 2017.

MORE ABOUT THE PROBE STUDY 


Date last reviewed: 24 March 2017
Phase 2 of the PROBE study aimED to test:
  • Whether the survey questions will capture consistent responses if they are repeated twice in the same Australian community
  • The stability of the online survey.

Australia joined a number of other countries in the Phase 2 reproducibility test, including Canada, Nigeria, Poland, United States and Vietnam.

In Australia, there were two survey rounds in Phase 2 to compare results:

Round 1: 20 September - 27 November 2016
Round 2: 28 November 2016 - 20 February 2017

Survey participants were welcome to complete both rounds.

Who cOULd participate?

You were welcome to complete the survey if you live in Australia, are 18+ years old and:

  • Have haemophilia or carry the gene
  • Or are the partner, family member or caregiver of someone with a bleeding disorder, but do not have a bleeding disorder yourself.
