Background
Inividuals with nephrotic syndrome (NS) experience fluid overload (FO) which can impact health-related quality of life (HRQOL). In partnership with the Food and Drug Administration (FDA), Prepare-NS aims to create and validate clinical outcome assessments (COAs) of FO in NS for use in drug development.
Methods
Context of use includes the following NS diagnoses: FSGS, minimal change disease, childhood-onset (not biopsied), membranous nephropathy, and IgM nephropathy. Participants with swelling in the past 90 days and not on dialysis volunteered via study website to complete an interview and consent (parental for participants under 18) was obtained. Concept elicitation interviews occurred via Zoom or phone and discussed how NS impacts functioning. Interview transcripts were coded in NVivo by two independent raters according to established standards for qualitative analysis. Recurring themes informed the conceptual model.
Results
To date, 25 participants have completed interviews. Image 1 shows participant demographics. Themes overall were consistent among age, sex, race, and diagnostic subgroups. Image 2 shows the conceptual model.
Conclusion
FO impacts HRQOL in the domains of physical function, fatigue, pain, sleep disturbance, gastrointestinal symptoms, appetite loss, and other essential functions. The next phase of Prepare-NS will be to develop the PRO inclusive of items to assess the impact of FO that is likely to be modifiable in NS disease modifying drug development.
