Change in Health Status After Acute Stroke
2021, Cerebrovascular, All Patients
The graph illustrates the percentage of patients who improved, worsened, or were stable approximately 1 year after acute stroke. Analysis was restricted to patients who had abnormal scores at baseline. Meaningful change was defined as a 5 point change in score for all scales.¹
For PROMIS Global Mental and Physical Health, PROMIS Physical Function, PROMIS Social Role Satisfaction, PROMIS General Self-Efficacy, and PROMIS Managing Symptoms Self-Efficacy, higher score is indicative of better health, and a score of 45 or less is considered abnormal (one-half standard deviation below the mean of the general population). For PHQ-9, higher score indicates more depressive symptoms and a score of 10 or higher indicates at least moderate depression. For all other scales, higher score is indicative of worse health, and a score of 55 or higher is considered abnormal (one-half standard deviation above the mean of the general population).
