Research has shown that the public overestimates the survival chances of patients after cardiopulmonary resuscitation. Other studies have suggested that demonstrably exaggerated survival rates in medical television fiction might affect these estimates. Such studies were mostly conducted in the United States, dealt with cardiopulmonary resuscitation in general, and asked respondents to indicate their source of medical information, an unreliable survey technique.
To examine whether public perceptions of survival after inhospital cardiopulmonary resuscitation by physicians and nurses is related to the consumption of medical drama, without relying on respondents' self-reports of what influences them. To examine whether training in basic cardiopulmonary resuscitation techniques mediates this relationship.
A random sample of 820 third and fifth year secondary school students completed a questionnaire in which they indicated their consumption of medical television fiction, their practical knowledge of cardiopulmonary resuscitation techniques, and their estimates of the survival rate after inhospital cardiopulmonary resuscitation.
A relationship was found between the consumption of medical television drama and higher estimates of cardiopulmonary resuscitation survival. Practical knowledge of cardiopulmonary resuscitation also resulted in increased estimated survival rates. An interaction effect of drama and practical knowledge was found. Respondents with practical knowledge were less affected by television.
The consumption of medical television drama is related to overestimating survival chances after inhospital resuscitation by physicians and nurses following cardiopulmonary arrest. A practical knowledge of basic cardiopulmonary resuscitation techniques moderates but does not eliminate the television effect.
研究表明，公众高估了心肺复苏术后患者的存活几率。其他研究表明，医学电视剧中明显夸大的存活率可能会影响这些估计。此类研究大多在美国进行，涉及一般的心肺复苏，并要求受访者指出其医疗信息来源，这是一种不可靠的调查技术。
在不依赖受访者关于影响因素的自我报告的情况下，研究公众对医生和护士进行院内心肺复苏术后存活情况的认知是否与医学剧的观看量有关。研究基本心肺复苏技术培训是否会调节这种关系。
对820名初三和高三学生进行随机抽样，让他们填写一份问卷，问卷中他们需表明自己观看医学电视剧的情况、心肺复苏技术的实践知识以及对院内心肺复苏术后存活率的估计。
发现观看医学电视剧与对心肺复苏存活情况的更高估计之间存在关联。心肺复苏的实践知识也会使估计的存活率提高。发现了电视剧观看量与实践知识之间的交互作用。有实践知识的受访者受电视的影响较小。
观看医学电视剧与高估医生和护士在心脏骤停后进行院内复苏后的存活几率有关。基本心肺复苏技术的实践知识会缓和但不会消除电视的影响。
