Summary
The PROBE Phase-3 study will collect data on patient reported outcomes, burdens, and experiences in patients living with hemophilia. The investigators will perform comparisons among countries, within country over time, within country against national normative data.
Description
BACKGROUND
The PROBE questionnaire is a tool for the assessment of patient-reported outcome, burdens and experiences. Until now, it has been used in persons living with hemophilia (PWH) and healthy controls. In phase 1 of the study, the investigators developed the questionnaire. In phase 2 of the study, the investigators evaluated the reliability, reproducibility, responsiveness, and costs of PROBE. The tool has been tested across 21 countries and it has been shown that PROBE is a valid questionnaire for the evaluation of patient reported outcomes (PROs) in PWH and control populations. The questionnaire is available in 11 languages (with 20 localized versions worldwide), and another 17 languages and 45 more localizations are in the process of development.
CURRENT STUDY and FUTURE DIRECTIONS
Phase 3 is the natural prosecution of the project. In this phase, the investigators aim at maintaining the capacity to collect data on PROBE, and the infrastructure will also be modified in order to allow for longitudinal collection of PROBE data (in previous phases, the investigators only collected anonymized data).
The objective of the study is to compare data on PROBE between countries, within-countries over time, and within-countries against national normative data. Reports will be produced every 2 years. Data collected during phase 2 of the study will also be used.
At the same time, the research framework will have the potential for:
- Expanding country participation within existing and new regions.
- Integrating the PROBE questionnaire in clinical trials, longitudinal studies, health technology assessment studies, routine clinical care, and registries.
- Using PROBE in new countries
- Testing the performance of the PROBE questionnaire in new patient populations
