Efficacy of Five Strategies To Improve Stroke Awareness in the Spanish-Speaking Population

Not Applicable

Completed

• Conditions: Stroke Acute
• Interventions: Behavioral: Mnemonic-Based Educational Training for Stroke Symptom Recognition

• Registration Number: NCT06613828
• Lead Sponsor: Instituto Mexicano del Seguro Social

Brief Summary

The goal of this experimental study is to evaluate the efficacy of five educational strategies for recognizing early symptoms of cerebrovascular disease (CVD) in the general adult population. The main questions it aims to answer are:

- How effective are the strategies RAPIDO, CORRE, DALE, CAMALEON, and ICTUS 911 in improving the recognition of early CVD symptoms?

Researchers will compare these strategies to determine which one leads to the highest increase in symptom recognition. Participants will receive a brief educational session on one of the five strategies and will:

* Complete a pre- and post-intervention survey (Stroke Awareness Questionnaire, SAQ).

* Receive short training on CVD symptoms and the urgency of contacting emergency services.

The primary outcome is the improvement in SAQ scores, and the secondary outcome is the proportion of participants achieving adequate knowledge of CVD symptoms.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 435

Inclusion Criteria

• Age: Participants must be 18 years or older.
• Consent: Participants must provide informed consent to participate in the study.
• General Population: Participants from the general public, regardless of their health insurance status or previous medical history (except as specified in exclusion criteria).
• Language: Participants must be fluent in Spanish, as the educational interventions are based on Spanish-language mnemonic strategies.

Exclusion Criteria

• History of Stroke: Participants with a previous diagnosis of cerebrovascular disease (stroke) will be excluded.
• Cognitive Impairment: Participants who are unable to understand or complete the Stroke Awareness Questionnaire (SAQ) due to cognitive or communication impairments will not be eligible.
• Incomplete Evaluation: Participants who are unable to complete both the pre- and post-intervention assessments will be excluded from the study.

Elimination Criteria:

• Lack of Follow-Up: Participants who fail to attend the second evaluation (7 days post-intervention) will be excluded from the final analysis.
• Withdrawal of Consent: Participants who choose to withdraw from the study at any time will be eliminated from further participation.

Arm && Interventions

Group	Intervention	Description
RAPIDO Strategy Arm	Mnemonic-Based Educational Training for Stroke Symptom Recognition	Participants in this arm receive educational training based on the RAPIDO strategy, an acronym developed to raise awareness of stroke symptoms among the Spanish-speaking community. This strategy is modeled after the English FAST mnemonic and focuses on the rapid identification of stroke symptoms.
CORRE Strategy Arm	Mnemonic-Based Educational Training for Stroke Symptom Recognition	Participants in this arm are trained using the CORRE strategy, created by a Colombian neurologist. It mirrors the structure of other mnemonic-based interventions and emphasizes the importance of quickly recognizing and acting upon early stroke symptoms.
DALE Strategy Arm	Mnemonic-Based Educational Training for Stroke Symptom Recognition	Participants in this arm are educated using the DALE strategy, developed in 2012 by researchers at the University of Guadalajara. Similar to the RAPIDO strategy, DALE adapts the FAST mnemonic for the Spanish-speaking population, promoting quick recognition and response to cerebrovascular symptoms.
CAMALEON Strategy Arm	Mnemonic-Based Educational Training for Stroke Symptom Recognition	In this arm, participants receive training based on the CAMALEON strategy, a mnemonic created in Costa Rica with the support of the pharmaceutical industry. The approach is designed to facilitate the recognition of early stroke symptoms by adapting the FAST mnemonic to Spanish.
ICTUS 911 Strategy Arm	Mnemonic-Based Educational Training for Stroke Symptom Recognition	Participants in this arm are educated using the ICTUS 911 strategy, which differs from the other four in that it is not directly based on a literal translation of FAST. Instead, it focuses on recognizing stroke symptoms and immediately calling emergency services (911) upon suspicion of a stroke.

Primary Outcome Measures

Name	Time	Method
Change in Stroke Awareness Questionnaire (SAQ) Score	Pre-intervention and 7 days post-intervention.	This measure will assess the change in participants\' knowledge of stroke symptoms before and after receiving the educational intervention. The SAQ evaluates awareness of stroke symptoms, risk factors, and appropriate responses to suspected stroke events.

Secondary Outcome Measures

Name	Time	Method
Proportion of Participants with Adequate Knowledge of Stroke Symptoms	7 days post-intervention.	This outcome measures the proportion of participants who achieve a predetermined \"adequate knowledge\" score on the SAQ, defined as correctly identifying at least 3 stroke symptoms and understanding the need to contact emergency services (911) within 3 hours of symptom onset.
