Effectiveness of an Interdisciplinary, Nurse Driven In-Hospital Code Stroke Protocol on In-Patient Ischemic Stroke Recognition and Management.

ABSTRACT

BACKGROUND: In-hospital strokes account for up to nearly 1 in 5 strokes. Clinical outcomes, such as length of stay, disability, and mortality are worse for in-hospital strokes than for those that occur in the community. For a variety of reasons, stroke can be more difficult to recognize and treat in hospitalized patients. Earlier recognition of stroke results in better clinical outcomes, presumably due to faster diagnosis and subsequently, prompt treatment. METHODS: This investigation was a retrospective, interrupted time series, observational study of all in-hospital stroke patients between 2008 and 2017. This investigation was a quality improvement project, and a waiver was granted from the institutional review board. We used Lean methodologies to standardize our stroke protocol and optimize skill-task alignment to improve the time from onset of symptoms to brain imaging (primary outcome). RESULTS: Overall, we observed significant improvement in the time from onset of symptoms to brain imaging from a median of 69 minutes to 37 minutes (P = .002). CONCLUSIONS: If successfully implemented, this approach may be useful in other care settings with potential to improve stroke outcomes, and decrease associated complications of stroke.
