Study Details

Study Description

Brief Summary

The PROFA study is an international, multi-centric observational and validation study to assess the patient-reported, psychosocial and economic outcomes of patients with Friedreich Ataxia (FA). Eligible patients will be recruited from six study centers in Germany, Austria and France. Patients will complete a baseline assessment via face-to-face interviews at the study centers and multiple momentary follow-up assessments via a mobile-health app at home daily to monthly for six months. Study results will gain essential and in-depth insights into the daily life of patients with FA.

Friedreich Ataxia

Detailed Description

There is a lack of knowledge about the patient-reported, psychosocial, and economic impact of Friedreich's Ataxia (FA). The few previous studies were based on small sample sizes and annual cross-sectional data, limiting the generalizability of the results.

Therefore, the PROFA study aims

to assess the acceptability, feasibility, and usability of a mobile-health app for the collection of longitudinal real-time data,
to determine healthcare costs from a societal perspective that includes informal care productivity losses, to assess associated factors and to analyze the impact of evidence-based treatment on costs,
to validate measures of health-related quality of life (HRQoL), to assess patients' HRQoL and its fluctuation over time and identify associated factors,
to develop, validate and evaluate a new measure of hearing and speech disabilities' impact on patients' psychosocial health, and
to evaluate interaction effects between HRQoL, psychosocial health and economic outcomes in patients with FA.

Thus, the PROFA study will gain a comprehensive understanding of the individual, societal, and economic burden of FA, identifying determinants of health and social life and efficient use of healthcare resources. This is crucial to improve the treatment, care, and everyday life of FA patients and their families.

This validation and observational study will recruit patients from six study centers (Germany, France, and Austria). The data assessment will be based on (i) a baseline assessment via interviews at the study centers and (ii) a subsequent remote momentary data assessment via a mobile-health app on a daily to monthly basis for six months, covering assessments of ataxia severity, HRQoL, psychosocial health, speech and hearing disabilities, health services utilization, and specific health events. Descriptive and multivariate statistics will be used to describe the impact of FA on the patient-reported HRQoL, psychosocial health and economic outcomes.

Outcome Measures

Primary Outcome Measures

Usability of the mobile-health app as a remote monitoring momentary data assessment tool [Six months]
Completeness of data
Acceptability of the mobile-health app as a remote monitoring momentary data assessment tool [Month 6]
Acceptability is assessed by a self-developed questionnaire (asking patients to rate the app based on user experience)
Total societal costs [Six months]
Aggregated healthcare costs of utilized healthcare services, informal care and productivity losses
Health-realted quality of life [Month 1]
Health-related quality of life assessed by the "Patient Reported Outcome Measures for Ataxia" Short-Form (PROM-ATAX), with a score range between 0 to 40 with higher scores indicating lower health-related quality of life
Health-realted quality of life [Month 3]
Health-related quality of life assessed by the "Patient Reported Outcome Measures for Ataxia" Short-Form (PROM-ATAX), with a score range between 0 to 40 with higher scores indicating lower health-related quality of life
