Background:
In patients with stroke undergoing endovascular treatment (EVT), long-term outcome is usually only evaluated by the modified Rankin Scale (mRS). Patient-reported outcomes (PROMs) are standardized assessments that consider clinical outcomes from the perspective of the patient. We aimed to evaluate PROMs through a smartphone-based communication platform in patients with stroke who received EVT.
Methods:
Consecutive patients with stroke who underwent EVT were offered to participate in the PROMs-through-App program (NORA). A set of standardized PROMs were collected at 7, 30 and 90 days after discharge. Disability was determined by clinicians (mRS) at 90 days. To characterize the potential ceiling effect of mRS in the assessment of different domains, the rate of abnormal PROMs among patients with excellent outcome (mRS 0-1) was calculated.
Results:
From June 2020 to October 2021, 186 patients were included. The median PROMs collection rate per patient was 80% (50-100%). A correlation was consistently seen between disability measured by mRS and the different PROMs. The rate of abnormal PROMs ranged from 20.83% (HADS at 7 days) to 59.61% (Mental PROMIS at 7 days). At 90 days, among patients with an excellent outcome, the rate of abnormal PROMs ranged from 8.7% (HADS) to 47.83% (Physical PROMIS).
Conclusions:
A specifically designed digital platform allows a high collection rate of PROMs among stroke patients who underwent EVT. The mRS score shows a ceiling effect and seems insufficient to fine-tune long-term clinical results. The use of PROMs may allow a better characterization of long-term outcome profiles after EVT.
