Basic Life Support (BLS) is a critical life-saving intervention for individuals experiencing cardiac arrest, respiratory distress, or airway obstruction. Medical students, as future frontline healthcare providers, are expected to possess adequate knowledge, positive attitudes, and competent practical skills in BLS. However, studies have reported deficiencies in these areas among medical students globally. Objective: This study aimed to assess the knowledge, attitude, and practice of Basic Life Support among clinical medical students at the University of Benin, Edo State, Nigeria. Methods: A descriptive cross-sectional study was conducted among 452 clinical medical students (400L to 600L) at the University of Benin. A stratified random sampling technique was used to select participants. Data were collected using a structured, self-administered questionnaire adapted from previous studies and based on the American Heart Association (AHA) 2020 BLS guidelines. The questionnaire assessed socio-demographic characteristics, knowledge (13 items), attitude (7 items on a Likert scale), and practice (10 items) of BLS. Data were analyzed using IBM SPSS version 27.0. Descriptive statistics were presented as frequencies and percentages. Associations between categorical variables were tested using the Chi-square test, and logistic regression was used to identify predictors of good KAP. A p-value < 0.05 was considered statistically significant. Results: A total of 452 questionnaires were distributed and retrieved, yielding a 100% response rate. The mean age of respondents was 22.92 ± 2.74 years, and 59.5% were male. Overall, only 30.8% of respondents demonstrated good knowledge of BLS, while 69.2% had poor knowledge. Knowledge improved significantly with academic level (p < 0.001), with 600-level students showing the highest proportion of good knowledge (43.6%). Female students had significantly better knowledge than males (p = 0.029). Regarding attitude, 78.5% of respondents demonstrated a good attitude towards BLS, while 21.5% exhibited a poor attitude. The majority (96.0%) agreed that BLS is necessary for medical students, and 91.4% supported its inclusion in the medical school curriculum. However, practice levels were markedly low, with 86.5% demonstrating poor practice. Only 13.5% had good practice scores. Mannequin training was significantly associated with better practice (p = 0.026). Major barriers to BLS acquisition and performance included limited availability of BLS training (68.8%), lack of practice opportunities (67.9%), fear of causing harm (56.9%), and fear of legal consequences (50.9%). Furthermore, 57.7% of respondents did not believe their medical school provided adequate BLS training, and 70.8% were uncomfortable using an Automated External Defibrillator (AED). Conclusion: This study revealed significant gaps in the knowledge and practice of BLS among clinical medical students at the University of Benin, despite a generally positive attitude towards its importance. The lack of formal training, inadequate hands-on practice with mannequins, and psychological barriers such as fear were identified as major hindrances.
