Redefining Disability: Patient-Reported Outcome Measures After Minor Stroke and Transient Ischemic Attack.

BACKGROUND: Long-term outcome assessment patients with stroke is not fully captured by usual clinical scales such as the modified Rankin Scale (mRS). Patient-reported outcome measures (PROMs) are standardized and validated assessments that consider clinical outcomes from the patient perspective. We aim to analyze the added value of PROMs in patients with transient ischemic attack and minor stroke. METHODS: We included consecutive patients with minor stroke or transient ischemic attack (National Institutes of Health Stroke Scale score 0-5) from April 2020 to October 2021 that participated in the PROMs-through-App program (NORA, NoraHealth Barcelona Spain). Clinician and self-evaluated outcomes were assessed at 90 days: clinician-evaluated mRS, self-reported mRS, the 10-item patient-reported outcome measures questionnaire global health survey (v1.2), Hospital Anxiety and Depression Scale, and the Fatigue Assessment Scale. We evaluated the acceptability (response rate), reliability (internal consistency), and construct validity (correlation with mRS and between scales) of each questionnaire. RESULTS: We included 355 patients in the analysis, response rate was patient-reported outcome measures questionnaire 71.3% (253), Hospital Anxiety and Depression Scale 70.7% (251), Fatigue Assessment Scale 71.8% (255), and self-assessed mRS 66.8% (237). PROMS internal consistency was good or excellent, while agreement between clinician and self-reported mRS was fair (k=0.34). Rate of abnormal PROMS scores were as follows (all responders versus clinician-reported mRS score 0-2): patient-reported outcome measures questionnaire mental health (43.1% versus 36.3%), physical health (48.6% versus 43.6%); Hospital Anxiety and Depression Scale-anxiety (21.9% versus 17.7%) and depression (17.1% versus 13.3%); and Fatigue Assessment Scale (40.8% versus 36.4%). PROMs scores correlated with clinician and self-reported mRS at 90 days. CONCLUSIONS: Evaluation of PROMs using a mobile-app-based communication system is a reliable and valid strategy to assess the outcome of patients from their perspective after a mild stroke or transient ischemic attack.

Added value of patient-reported outcome measures (PROMs) after an acute stroke and early predictors of 90 days PROMs.

INTRODUCTION: Value-based health care represents a patient-centered approach by valuing Patient-Reported Outcome Measures (PROMs). Our aim was to describe the additional value of PROMs after an acute stroke over conventional outcome measures and to identify early predictors of poor PROMs. METHODS: Acute stroke patients discharged from a tertiary care hospital followed by a web/phone-based PROMs collection program in the post hospitalization phase. Main PROMs involve anxiety and depression (HADS) (each defined by HADS ≥ 10) and global physical (PHY-) and mental (M-) health (PROMIS-10). PROMIS cut-off raw values of normality were: PHY-PROMIS ≥ 13 and M-PROMIS ≥ 11. An overall health status (OHS) from 0 to 100 was also determined. PROMs related to the different modified Rankin Scale (mRS) grades were defined. Early predictors of PROMs were evaluated. RESULTS: We included 1321 stroke patients, mean age 75 (± 8.6) and 55.7% male; 77.7% returned home. Despite a favorable mRS at 3 months (< 3), a relevant rate of patients considered without symptoms or with mild disability showed unfavorable results in the measured PROMs (8% unfavorable OHS, 15% HAD-depression, 12.1% HAD-anxiety, 28.7% unfavorable M-PROMIS and 33.1% unfavorable PHY-PROMIS results). Along follow-up, only PHY-PROMIS and OHS showed significant improvement (p < 0.01 and 0.03, respectively). The multivariate analysis including discharge variables showed that female sex, higher discharge mRS and discharge to socio-rehabilitation-center (SRC) were independent predictors of unfavorable results in PROMs (p < 0.01). When adding 7 days PROMs results, they emerged as the strongest predictors of 3 months PROMs. CONCLUSIONS: A high proportion of stroke patients show unfavorable results in PROMs at 3 months, even those with favorable mRS, and most results obtained by PROMs during follow-up continued to indicate alterations. Female sex, mRS and discharge to SRC predicted unfavorable results in PROMs, but the strongest predictors of 3 months PROMs were the results of the 7 days PROMs.
