Background: A fundamental gap between clinical prevention and self-management awareness heightens the risk for stroke recurrence in approximately one-fourth of the highest risk stroke survivors annually.Secondary stroke prevention has the potential to be promoted by mobile health (mHealth) applications for effective real-world adoption of vascular risk factor mitigation. This scoping review aims to evaluate the impact of mHealth interventions and their effectiveness to reduce recurrent stroke rates among stroke survivors in randomized controlled trials (RCTs).Methods: Scoping review in Ovid Medline, Cochrane Library, CINAHL, and Scopus for RCT literature employing mHealth among stroke populations published in English from 2010 to November 19, 2020. Small or pilot studies that included randomized design were included.Results: A total of 352 abstracts met inclusion criteria; 31 full-text articles were assessed and 18 unique RCTs involving 1,453 patients ultimately fulfilled criteria. Twelve of 18 met the pre-defined primary outcome measure, including 2 studies evaluating feasibility. Eight of 18 only addressed recovery from index stroke deficits. Most outcomes focused on self-reported functional status, mood, quality of life or compliance with intervention; primary outcome was an objective metric in 4/18 (blood pressure readings, step number, obstructive sleep apnea support compliance). Intervention duration 2-12 months, with a median 9 weeks. Conclusions:No high-quality evidence supporting mHealth applications to reduce recurrent stroke was found in this scoping review. Overall, most studies were relatively small, heterogenous, and employed subjective primary outcome measures. mHealth's potential as an effective tool for stroke stakeholders to reduce recurrent stroke rates has not been sufficiently demonstrated in this review. Future randomized studies are needed that explicitly evaluate stroke recurrence rate.
Introduction: Telestroke is an effective strategy to increase appropriate stroke treatments among patients in resource-limited environments. Despite the well-documented benefits of telestroke, there is limited literature regarding its utilization. The purposes of this study are: (1) determine the percentage of potential stroke patients who generate a telestroke consult in rural critical access hospitals (CAHs) and (2) validate an electronic medical record (EMR)-derived report as a stroke screen. Methods: This retrospective chart review analyzed patients presenting between September 1, 2020 and February 1, 2021 to three CAHs. Visits with triage complaints suggesting acute ischemic stroke (AIS)/transient ischemic attack (TIA) were pooled for analysis using an EMR-derived report. Patients with confirmed AIS/TIA at discharge over this period were used to validate the EMR tool. Results: The EMR report pooled 252 possible AIS/TIA visits out of 12,685 emergency department visits for analysis. It had a specificity of 98.78% and sensitivity of 58.06%. Of the 252 visits, 12.7% met telestroke criteria and 38.89% received telestroke evaluation. Among these, a definite diagnosis of AIS/TIA was made in 92.86%. Of the remaining population who met criteria but didn't undergo consultation, 61.11% were diagnosed with AIS/TIA at discharge. Conclusion: This study provides novel characterization of stroke presentations and telestroke in rural CAHs. The EMR-derived report is a reasonable tool to concentrate potential AIS/TIA cases for review and resource allocation but is not sensitive enough to detect stroke as a stand-alone tool. The majority (56%) of eligible patients did not undergo telestroke consultation. Future studies are critical to further understand reasons contributing to this.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
