Despite the importance of early effective chest compressions to improve the chance of survival of an out-of-hospital cardiac arrest victim, it is still largely unknown how willing our Malaysian population is to perform bystander cardiopulmonary resuscitation (CPR).
We conducted a voluntary, anonymous self-administered questionnaire survey of a group of 164 final year medical students and 60 final year dental students to unravel their attitudes towards performing bystander CPR.
Using a 4-point Likert scale of "definitely yes," "probably yes," "probably no," and "definitely no," the students were asked to rate their willingness to perform bystander CPR under three categories: chest compressions with mouth-to-mouth ventilation (CC + MMV), chest compressions with mask-to-mouth ventilation (CC + PMV), and chest compressions only (CC). Under each category, the students were given ten hypothetical victim scenarios. Categorical data analysis was done using the McNemar test, chi-square test, and Fisher exact test where appropriate. For selected analysis, "definitely yes" and "probably yes" were recoded as a "positive response."
Generally, we found that only 51.4% of the medical and 45.5% of the dental students are willing to perform bystander CPR. When analyzed under different hypothetical scenarios, we found that, except for the scenario where the victim is their own family member, all other scenarios showed a dismally low rate of positive responses in the category of CC + MMV, but their willingness was significantly improved under the CC + PMV and CC categories.
This study shows that there are unique sociocultural factors that contribute to the reluctance of our students to perform CC + MMV.
尽管早期有效的胸外按压对于提高院外心脏骤停患者的生存几率至关重要，但马来西亚民众进行旁观者心肺复苏术（CPR）的意愿仍很大程度上不为人知。
我们对164名医学专业最后一年的学生和60名牙科专业最后一年的学生进行了一项自愿、匿名的自填式问卷调查，以了解他们对进行旁观者心肺复苏术的态度。
使用“肯定愿意”“可能愿意”“可能不愿意”和“肯定不愿意”的4级李克特量表，要求学生对在三种情况下进行旁观者心肺复苏术的意愿进行评分：胸外按压加口对口通气（CC + MMV）、胸外按压加面罩对口通气（CC + PMV）以及仅胸外按压（CC）。在每种情况下，给学生提供十个假设的受害者场景。在适当的情况下，使用麦克尼马尔检验、卡方检验和费舍尔精确检验进行分类数据分析。对于选定的分析，“肯定愿意”和“可能愿意”被重新编码为“积极回应”。
总体而言，我们发现只有51.4%的医学专业学生和45.5%的牙科专业学生愿意进行旁观者心肺复苏术。在不同的假设场景下进行分析时，我们发现，除了受害者是自己家庭成员的场景外，在CC + MMV类别中，所有其他场景的积极回应率都极低，但在CC + PMV和CC类别下，他们的意愿有显著提高。
本研究表明，存在一些独特的社会文化因素导致我们的学生不愿进行CC + MMV。
