Factors Affecting the Occurrence of Out-of-Hospital Sudden Cardiac Arrest

Area of Science:

• Emergency Medicine
• Public Health
• Cardiology

Background:

• Out-of-hospital sudden cardiac arrest (OHSCA) poses a significant challenge to emergency medical services.
• Prioritizing interventions and resource allocation requires understanding OHSCA risk factors.
• Current emergency call procedures may not adequately incorporate clinical risk assessment for OHSCA.

Purpose of the Study:

• To identify significant risk factors for OHSCA.
• To inform decisions regarding emergency intervention prioritization and resource deployment.
• To enhance the effectiveness of pre-hospital emergency procedures.

Main Methods:

• Retrospective study design.
• Analysis of medical records from Emergency Medical Service in Wroclaw, Poland.
• Utilized the International Classification of Diseases (ICD-10) for data categorization.

Main Results:

• The primary risk factors for OHSCA include external causes (ICD Group V) and endocrine disorders (ICD Group E), particularly diabetes.
• Increased OHSCA risk is associated with nervous system diseases (ICD Group G, e.g., epilepsy), respiratory diseases (ICD Group J, e.g., COPD, asthma), and mental/behavioral disorders (ICD Group F, including drug-related issues).
• Existing emergency notification protocols do not currently integrate clinical OHSCA risk factors.

Conclusions:

• Knowledge of OHSCA risk factors can optimize rescue operations, from initial assessment to medical team deployment.
• Effective medical emergency treatment and OHSCA prevention strategies can be improved by understanding these factors.
• Implementing risk factor awareness may lead to reduced healthcare costs associated with emergency interventions.
