Background Successful implementation of Basic life support (BLS) is critical to improving survival rates and outcomes, especially among healthcare workers. To our knowledge, there is no available literature pertaining to the level of BLS knowledge of health care professionals in Yemen. Methods Data was collected for this cross-sectional descriptive study from June to August 2020, using a 10-item questionnaire related to cardiopulmonary resuscitation (CPR) and BLS, along with questions on socio-demographic characteristics. Participants were nurses in public and private hospitals located in Al-Rahida and Al-dimna cities, Taiz governance and Hodeidah city, Hodeidah governance in Yemen. Results Out of 220 distributed questionnaires, 200 were returned with a response rate of 90.9%. More than a half (53.65%) of answer choices for BLS knowledge were correct. There was a significant difference in knowledge score based on level of education where those who had Bachelor degree had more knowledge (P = 0.000). Those who said they had received training in CPR or received information about CPR had significantly higher scores than those who did not receive (P = 0.000). Conclusions BLS knowledge among nurses in Yemen is below an acceptable level to ensure maximum survival in the event of cardiac arrest. Disseminating BLS information and training in a cost effective and efficient manner will provide a large benefit in terms of lives saved with minimal costs.

Introduction Vaccines are considered preventive measures to reduce coronavirus disease 2019 (COVID-19) spread around the world. There are many factors for adherence and acceptance of COVID-19 vaccination. Objectives The study aimed to investigate nursing students’ knowledge, perception, and factors that influence their adherence to COVID-19 vaccines. Methods A descriptive cross-sectional study design was conducted among nursing students at the Faculty of Nursing, Mansoura University, Egypt, during the period between September 1 and November 30, 2021. Results Of the total of 500 participants, 76% took a COVID-19 vaccination. About 89% of participants rated the correct answer related to COVID-19 vaccination. Obligatory to enter the faculty, protect family and friends, and protect myself were the most reasons of adherence (80.3, 73.7, and 70.8%, respectively) while fear of adverse events and lack of information about vaccine were the most reasons of nonadherence (87.5 and 79.2%, respectively) to COVID-19 vaccination. The majority of participants (62%) had expressed positive perception toward COVID-19 vaccination. Education level, training program about COVID-19, previous infection with COVID-19, perception toward COVID-19 vaccination, and knowledge toward COVID-19 vaccination were significantly ( p   =   .035, p   =   .027, p   =   .009, p   =   .008 and p   =   .033, respectively) associated with students’ adherence to take COVID-19 vaccines. Conclusion Accurate knowledge and perception about COVID-19 vaccines are the stronger predictors of vaccine hesitance or acceptance among nursing students in Egypt. Campaigns to increase knowledge and perception of COVID-19 and its vaccines among nursing students are needed to improve vaccine acceptance and reduce vaccine hesitance.
