Impact of Pre-Hospital and in-Hospital Optimization on the Management of Intravenous Thrombolysis in Hyperacute Ischemic Stroke: A Scoping Review.

INTRODUCTION

Stroke is the second leading cause of death worldwide and ranks third as a cause of disability. The American Heart Association/American Stroke Association (AHA/ASA) recommends that treatment begin within three hours of onset with intravenous thrombolysis therapy. This scoping review aimed to identify the factors that influence the delay in intravenous thrombolysis (IVT) management in patients with ischemic stroke.

METHODS

We searched relevant studies in PubMed, ScienceDirect, and EBSCO and this review includes studies on ischemic stroke patients that analyze the factors contributing to delays in intravenous thrombolysis therapy, and it demonstrates that such delays are present in the management of IVT.

RESULTS

A total of 48 studies were included in this study. Among pre-hospital factors, the most frequently reported contributors to delays in IVT for acute ischemic stroke (AIS) patients were the use of Emergency Medical Services (EMS) (12 studies), mode of hospital presentation (12 studies), comorbidities (6 studies), symptom recognition (5 studies), and timing of event (5 studies), with several studies reporting statistically significant associations (p<0.05). Emergency department use shortened hospital admission time by an average of 30 minutes, p<0.05Regarding in-hospital delay factors, the main contributors to delays included long scan times (5 studies), low NIHSS scores (5 studies), and limited implementation of stroke programs (5 studies). Other in-hospital delay variables included delayed activation of stroke codes (3 studies), inefficiency of human resources (3 studies), suboptimal triage processes (2 studies), diagnostic process (1 study), and logistics (1 study).

CONCLUSION

Delayed thrombolysis in ischemic stroke patients is caused by various factors, both pre-hospital and in-hospital. Community education and telemedicine can reduce delays by 30%. Collaboration between the community, stroke units, medical personnel, and the government through comprehensive programs is key in accelerating stroke treatment and improving patient clinical outcomes.
