Knowledge and Attitudes Towards ECG Interpretation Among Intensive Care Nurses: A Greek Cross-Sectional Study

Area of Science:

• Nursing Education
• Critical Care Medicine
• Cardiology

Background:

• Effective electrocardiogram (ECG) interpretation is crucial for timely cardiac arrhythmia recognition in Intensive Care Units (ICUs).
• Existing studies indicate knowledge gaps in ECG interpretation among nurses internationally.
• There is a need to assess the educational preparedness and role perception of ICU nurses in Greece regarding ECG interpretation.

Purpose of the Study:

• To evaluate the knowledge, attitudes, and self-perceived preparedness of ICU nurses in Greece concerning ECG interpretation.
• To identify demographic and professional factors associated with ICU nurses' ECG interpretation knowledge and attitudes.

Main Methods:

• A descriptive, cross-sectional web-based survey was conducted among 100 ICU nurses in Greece.
• The survey included demographic variables, 10 true/false knowledge items, and 10 Likert-scale attitude items.
• Data were analyzed using descriptive statistics, chi-squared tests, and multivariable logistic regression.

Main Results:

• The average knowledge score was 6.1/10, with high accuracy on basic ECG items (88%) but low performance on complex patterns (24%).
• Prior ECG training was the sole independent predictor of adequate knowledge (OR=2.85, p=0.028).
• While 96% deemed ECG interpretation essential, 49% reported limited knowledge, and 25% were uncertain about their role.

Conclusions:

• ICU nurses in Greece possess moderate theoretical ECG knowledge but exhibit variable preparedness and role clarity.
• Prior training, ICU type, and clinical experience significantly influence ECG interpretation competence.
• Standardized, simulation-based training and clear delineation of nursing responsibilities are recommended to enhance cardiac monitoring safety and patient outcomes.
