Effect of implementing care protocols on acute ischemic stroke outcomes: a systematic review

Implementing stroke care protocols has intended to provide better care quality, favor early functional recovery, and achieving long-term results for the rehabilitation of the patient.

To analyze the effect of implementing care protocols on the outcomes of acute ischemic stroke.

Primary studies published from 2011 to 2020 and which met the following criteria were included: population should be people with acute ischemic stroke; studies should present results on the outcomes of using protocols in the therapeutic approach to acute ischemic stroke. The bibliographic search was carried out in June 2020 in 7 databases. The article selection was conducted by two independent reviewers and the results were narratively synthesized.

A total of 11,226 publications were retrieved in the databases, of which 30 were included in the study. After implementing the protocol, 70.8% of the publications found an increase in the rate of performing reperfusion therapy, such as thrombolysis and thrombectomy; 45.5% identified an improvement in the clinical prognosis of the patient; and 25.0% of the studies identified a decrease in the length of hospital stay. Out of 19 studies that addressed the rate of symptomatic intracranial hemorrhage, 2 (10.5%) identified a decrease. A decrease in mortality was mentioned in 3 (25.0%) articles out of 12 that evaluated this outcome.

We have identified the importance of implementing protocols in increasing the performance of reperfusion therapies, and a good functional outcome with improved prognosis after discharge. However, there is still a need to invest in reducing post-thrombolysis complications and mortality.
