What is the purpose of using the NIH stroke scale?

A useful tool in quantifying neurologic impairment is the National Institutes of Health Stroke Scale (NIHSS) (see Table 2, below). The NIHSS enables the healthcare provider to rapidly determine the severity and possible location of the stroke.

When should NIH stroke scale be done?

When should the National Institutes of Health Stroke Scale (NIHSS) be performed? The initial NIHSS should be performed during initial evaluation, prior to t-PA decision.

What are the limitations to the NIH stroke scale?

The NIHSS is a 42-point scale, with minor strokes usually being considered to result in a score lower than 5. An NIHSS score higher than 10 correlates with an 80% likelihood of visual flow deficits on angiography.

What is a bad NIH score?

The NIH grant application scoring system uses a 9-point rating scale (1 = exceptional; 9 = poor) in whole numbers (no decimals) for Overall Impact and Criterion scores for all applications. NIH expects that scores of 1 or 9 will be used less frequently than the other scores.

What is considered a moderate stroke?

5–15 = moderate stroke. 15–20 = moderate/severe stroke. 21–42 = severe stroke.

How many patients are on the NIH stroke scale test?

To successfully complete this activity, learners must rate a test group of 3 patients by applying the scale in case-based scenarios.

What does a NIH stroke scale of 14 mean?

Very Severe: >25. Severe: 15 – 24. Mild to Moderately Severe: 5 – 14.

What is a stroke severity tool?

The NIHSS is a systematic assessment tool that provides a quantitative measure of stroke‐related neurological deficit. 18. The NIHSS was originally designed as a research tool to measure baseline data from patients in acute stroke clinical trials.

How is the NIH Stroke Scale used in clinical practice?

Now, the scale is also widely used as a clinical assessment tool to evaluate acuity of stroke patients, determine appropriate treatment, and predict patient outcome. The NIHSS can be used as a clinical stroke assessment tool to evaluate and document neurological status in acute stroke patients.

How long does it take to administer a stroke scale?

scale can be easily administered in about 5 minutes. Elements of the NIH Stroke Scale Healthcare providers administering the NIH Stroke Scale should be specifically trained to use the scale and should have a copy of the scale available when administering the assessment. Without training, the results are likely to be inconsistent.

What does a score of 16 mean on the stroke scale?

As a general rule, a score over 16 predicts a strong probability of patient death, while a score of 6 or lower indicates a strong possibility for a good recovery. Each 1-point increase on the scale lowers the possibility of a positive outcome for the patient by 17 percent.

Is the NIH Stroke Scale the same as the r-tPA?

Evolution of the NIHSS The original (Cincinnati/Naloxone) and the current (r-tPA) NIH Stroke Scales are shown to highlight the differences. An intermediate version (not shown) was used in the Pilot r-tPA for Acute Stroke Trial. 14 The instructions for the original version provided a stroke scale glossary.
