Description
Patient Inclusion Criteria:
- Patients with a documented diagnosis of FD
- Patients who have received ≥4 doses of ERT (with agalsidase alfa or agalsidase beta) for the treatment of FD.
- Patients who present to the participating hospital(s) or treatment centre(s) for administration of a dose of ERT (as part of their routine treatment) during the data collection period.
Caregiver Inclusion Criteria:
-Self-identifies as a caregiver of a patient with FD for whom written informed consent has been obtained for inclusion in the study.
Patient Exclusion Criteria:
- Patients who are unable or unwilling to give consent for study participation.
- Patients whose ERT preparation and administration takes place exclusively in the home setting with no HCP involvement in preparation of the infusion.
- For the time and motion evaluation: Patients whose ERT is administered by a HCP who does not consent to be observed.
Caregiver Exclusion Criteria:
- Caregiver (and/or the patient with FD whom they support or care for) is unable or unwilling to give consent for study participation.

HRQoL (SF-12 scores / responses)
Time Frame: up to 7 weeks
|
Health Related Quality of Life measured by the 12 Item Short Form Survey [SF-12]). SF-12v2 component summary measure and health domain scale is described in terms of scale or item composition, number of score levels, lowest and highest possible T scores for the standard and acute forms, and the health states associated with the lowest and highest observable scores. These descriptions are based on the general content of the scales and measures and the pattern of responses necessary to achieve these extreme scores. This information can be used to summarize what each component summary measure and health domain scale measures and can serve as a basis for broad-level interpretation of SF-12v2 results. These 8 domains form 2 subscales: physical component summary and mental component summary. The low scores indicate limitations in the domain measured. The high scores indicate less limitations in the domain measured. |
up to 7 weeks
|
Patients General wellbeing measured by WHO-5 scores / responses)
Time Frame: up to 7 weeks
|
World Health Organization-5 Wellbeing Index [WHO-5] consists of 5 items and the timeframe for responses is based on the previous 2 weeks.
The 5 items relate to feeling cheerful, calm, active, rested and being interested in life.
The raw score is calculated by totaling the figures of the five answers.
The raw score ranges from 0 to 25, 0 representing worst possible and 25 representing best possible quality of life.
|
up to 7 weeks
|
Patients Level of fatigue measured by Fatigue Likert scale)
Time Frame: up to 7 weeks
|
Questionnaire measuring Fatigue.
The range is from 1-5. 1 not at all tired, 5 extremely tired
|
up to 7 weeks
|
Patients Levels of work impairment (WPAI scores / responses)
Time Frame: up to 7 weeks
|
Work Productivity and Activity Index.
The WPAI consists of 6 items and ranges from 0-100%.
WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes.
|
up to 7 weeks
|
Caregiver's Levels of work impairment (WPAI-CG scores / responses).
Time Frame: up to 7 weeks
|
Work Productivity and Activity Index.
The WPAI consists of 6 items and ranges from 0-100%.
WPAI outcomes are expressed as impairment percentages, with higher numbers indicating greater impairment and less productivity, i.e., worse outcomes.
|
up to 7 weeks
|
Level of strain in providing care for a patient with FD (CSI scores / responses).
Time Frame: up to 7 weeks
|
Caregiver Strain index.
The CSI consists of 13 items and measures the strain of care provision in five domains (financial, physical, psychological, social and personal).
The range is from 0-13 and any positive answer may indicate a need for intervention in that area.
A score of 7 or higher indicates a high level of stress.
