To explore the circumstances and factors that explain variations in response to a cardiac event and to identify potentially modifiable factors.
Qualitative analysis of semistructured, face to face interviews with patients admitted to two district hospitals for a cardiac event and with other people present at the time of the event. Patients were divided into three groups according to the length of delay between onset of symptoms and calling for medical help.
43 patients and 21 other people present at the time of the cardiac event. Patients were divided into three groups according to the length of time between onset of symptoms and seeking medical help: non-delayers (< 4 h; n = 21), delayers (4-12 h; n = 12), and extended delayers (> 12 h; n = 10).
Decision making process, strategies for dealing with symptoms, and perception of risk and of heart attacks before the event according to delay in seeking help.
The illness and help seeking behaviour of informants had several components, including warning, interpretation, preliminary action, re-evaluation, and final action stages. The length of each stage was variable and depended on the extent to which informants mobilised and integrated resources into a strategy to bring their symptoms under control. There were obvious differences in informants' knowledge of the symptoms that they associated with a heart attack before the event. Non-delayers described a wider range of symptoms before their heart attack and twice as many (13) considered themselves to be potentially at risk of a heart attack compared with the other two groups. For most informants the heart attack differed considerably from their concept of a heart attack.
The most critical factor influencing the time between onset of symptoms and calling for professional medical help is that patients and others recognise their symptoms as cardiac in origin. This study suggests that various points of intervention in the decision making process could assist symptom recognition and therefore faster access to effective treatment.
探讨解释心脏事件反应差异的情况和因素,并确定潜在的可改变因素。
对两所地区医院收治的因心脏事件入院的患者以及事件发生时在场的其他人进行半结构化面对面访谈的定性分析。根据症状出现至呼叫医疗救助之间的延迟时间,将患者分为三组。
43名患者以及心脏事件发生时在场的21名其他人。根据症状出现至寻求医疗帮助之间的时间长短,将患者分为三组:无延迟者(<4小时;n = 21)、延迟者(4 - 12小时;n = 12)和延长延迟者(>12小时;n = 10)。
根据寻求帮助的延迟情况,决策过程、应对症状的策略以及事件发生前对风险和心脏病发作的认知。
被调查者的患病及寻求帮助行为有几个组成部分,包括预警、解读、初步行动、重新评估和最终行动阶段。每个阶段的时长各不相同,取决于被调查者将资源调动并整合到控制症状策略中的程度。事件发生前,被调查者对与心脏病发作相关症状的认知存在明显差异。与其他两组相比,无延迟者在心脏病发作前描述的症状范围更广,有两倍之多(13人)认为自己有心脏病发作风险。对大多数被调查者而言,心脏病发作与他们对心脏病发作的概念有很大不同。
影响症状出现至呼叫专业医疗救助之间时间的最关键因素是患者及其他人将其症状识别为心脏源性。本研究表明,决策过程中的各个干预点可有助于症状识别,从而更快获得有效治疗。
