IntroductionEmergency nurses are on the front line of patient care for suicidal persons, yet many nurses report feeling unprepared to effectively manage suicidal patients owing to a lack of suicide-specific training. The purpose of this study was to examine the suicide-specific training experiences of emergency nurses and evaluate how training relates to burnout, confidence, and comfort working with suicidal patients.MethodsEmergency nurses at critical access and community hospitals completed an anonymous online survey during work hours. The survey included questions about training experiences, burnout, confidence, and comfort working with suicidal patients, perceptions of the quality and interactive nature of training, and desires for future suicide-specific intervention training.ResultsGroup comparisons among the 117 emergency nurses revealed that those who received evidence-based/expert-delivered training reported greater confidence, comfort, and perceived ability to treat suicidal patients and lower burnout than those who received informal or no training. Those with informal training reported greater confidence and ability to treat suicidal patients, but similar levels of comfort and burnout as those with no training. Mediation analyses showed that training was associated with greater comfort working with suicidal patients through its effect on increased confidence. A majority desired additional suicide-specific training.DiscussionEvidence-based/expert-delivered professional training in suicide intervention is associated with improved confidence, comfort, and perceived ability to care for suicidal patients and lower burnout. Providing evidence-based suicide intervention training may improve quality of care for suicidal patients by improving emergency nurse confidence and comfort for treating these high-risk patients.  相似文献

As a result of sub-optimal immunization levels, measles has re-emerged in the EU since 2008 (30 567 cases in 2011), and nearly half of the cases reported are in France. Our objectives were to assess knowledge, attitudes, beliefs and practices of French general practitioners (GPs) towards measles and measles–mumps–rubella (MMR) vaccination. In 2012, we surveyed 329 GPs in southeastern France. Forty-five percent reported that they saw patients with measles in 2011. They considered the risk of complications low among 2–5-year-old children and young adults without co-morbidity. Twenty percent knew that two MMR doses are 99% effective in preventing measles. Nearly all (95%) GPs stated that they verified the MMR status for patients <30 years old in 2011 (42% systematically, 37% often, 15% sometimes). Seventy-nine percent reported proposing MMR vaccination to non-immune relatives in contact with a patient with measles. Participation in continuing medical education courses and considering measles to be a serious disease were independently associated with such post-exposure vaccination. GPs considered the following were potential barriers to the second dose of MMR (MMR2): parents/patients' belief that measles is harmless (80%), parents/patients' fear of the vaccine's side effects (50%), difficulty in documenting vaccination (48%) and lack of reminders for MMR2 (16%). Finally, some GPs also had misconceptions about the severity of measles (13%) and the usefulness of MMR2 (12%), which also served as barriers. In conclusion, it is essential to raise GPs' awareness of this disease and fill any gaps in their knowledge, by providing them with evidence-based information on measles and MMR vaccination.  相似文献

目的:调查山东省综合性三级医院临床护士疼痛管理知识和态度现状,为后续开展相关培训提供依据。方法:采用疼痛管理知识和态度调查问卷(KASRP)2014中文版问卷,对山东省30所综合性三级医院的766名临床护士进行调查,了解临床护士疼痛管理知识和态度的现状及存在的问题,并采用多元线性回归分析其影响因素。结果:临床护士KASRP评分为(21.12±4.64)分,平均得分率为51.51%;不同科室、职称、疼痛继续教育程度的临床护士疼痛管理知识与态度不同(P<0.05)。结论:临床护士疼痛管理知识有所欠缺,应注意提高低职称、非疼痛/肿瘤科室临床护士的知识水平和学习主动性,加强疼痛管理的继续教育和培训。  相似文献

目的:调查护士对“互联网+护理服务”态度、核心能力自评现状分析其影响因素。方法:2019年6月1日~7月1日,采用自行设计的一般资料调查问卷、护士对“互联网+护理服务”态度及核心能力自评调查问卷,对广州市5所“互联网+护理服务”试点三甲医院的1139名护士进行调查。结果:76.7%的护士对参与“互联网+护理服务”的意愿持积极态度;不同年龄、职称的护士对“互联网+护理服务”参与意愿比较差异有统计学意义(P<0.01,P<0.05);护士对“互联网+护理服务”核心能力的自评得分为(114.70±13.80)分,处于中等水平;不同婚姻状况、职称的护士核心能力自评比较差异有统计学意义(P<0.01,P<0.05)。结论:“互联网+护理服务”平台对护士具有较强的吸引力,但护士普遍对护患安全风险及医疗垃圾处理方面存在担忧;护士在核心能力方面亟待提高;因此,建立精细化的“互联网+护理服务”行业标准及培训机制势在必行。  相似文献

ObjectiveDespite the availability of well characterized and scientifically proven medicines, many people prefer the use of the less known herbal therapies that have no-scientific or evidence-based values as their first line of treatment. While this represents a growing worldwide issue, it is commonly practiced in developing countries including Saudi Arabia. Hence, the aim of the present study is to assess the prevalence of herbal medicine use, the most reported side effects and influencing factors in Saudi Arabia.DesignA community based cross sectional survey study.SettingsParticipants were recruited by convenience sampling method from local malls and family recreation sites.Main outcome measuresPrevalence of herbal medicine use and the associated risks.ResultsOut of the 1300 surveyed individuals, 1226 respondents (94 %) used herbal medicines for therapeutic purposes with the majority of the respondents using them based on traditional beliefs 699 (57 %) or family recommendations 417 (34 %). Young respondents <35 year olds who live in urban cities, showed a significantly better knowledge about herbal medicines use and the associated risks than their counterparts (p < 0.001). Despite the high percentage of reported side effects (46 %), more than half of the respondents 702 (54 %) use herbal medicines as their first line of therapy. However, the most reported reasons for the use of herbal medicine are the belief that they are safer, more effective and cheaper to buy than the standard medicines.ConclusionThere is a high prevalence use of non-scientifically proven herbal medicine and a low level of knowledge about their risks amongst participants.  相似文献

BackgroundEmergency nurses are expected to follow recent research findings and ensure that their practice is based on evidence. Yet, during busy work-shifts in overcrowded emergency departments, evidence-based practice (EBP) is not always implemented.AimTo describe emergency nurses’ EBP attitudes, self-efficacy, knowledge, skills and behaviours at the baseline of a RCT.MethodsA baseline study as a part of a randomised, single-blind controlled multicentre intervention trial (RCT). The study population consisted of 300 emergency nurses employed in two university hospitals’ emergency departments in Finland. The total sample size (n = 80) was estimated using a simulation approach. The data were collected from voluntary emergency nurses by using four structured questionnaires.FindingsEmergency nurses’ EBP attitudes, self-efficacy, knowledge and skills were above the average level, and their EBP behaviour was below the average level when measured with the other of the two sum variables measuring behaviour. A significant correlation was found between age, years since graduation, the length of working experience in health care and EBP attitudes, behaviour, knowledge and self-efficacy. Younger emergency nurses who had recently graduated and had shorter work experience showed more positive attitudes towards EBP than older counterparts. No correlation was found between gender, educational background or prior exposure to EBP and EBP attitudes, self-efficacy, knowledge, skills or behaviours.ConclusionsThis study showed that to promote emergency nurses’ use of EBP in future, tailored educational interventions on EBP are needed. This would ensure implementation of EBP in daily clinical practice for quality and effective patient care.  相似文献
