目的了解公共场所服务业人员对艾滋病及其传播途径的认知情况。方法2005年9月,采用匿名自填式问卷调查方法,调查深圳市公共场所服务业人员的一般人口社会学特征,对艾滋病的认知情况及影响因素进行分析。结果服务业人员对艾滋病知识有一定的了解,对其主要传播途径有较好的掌握,但在非传播途径的了解方面仍存在一些模糊认识。对安全套的预防作用认识不足。多数愿意接受艾滋病的健康检查。结论应进一步加强公共场所服务业人员的艾滋病教育,使其对艾滋病基本知识有一个全面的了解。推广使用安全套。同时加强预防艾滋病措施的宣传,出台相关的政策。 相似文献

中国乡级计划生育服务站技术服务提供及服务能力跨地区分析 总被引:1,自引:0,他引:1
目的根据2001年全国计划生育和生殖健康调查资料,对我国东、中、西部三大经济地区乡级计划生育服务站的技术服务提供及服务能力进行跨地区比较分析。方法全国抽样调查,采用分层、三阶段、概率比例抽样方法。对776个计划生育服务站和负责人采用观察与询问的方式进行问卷调查。结果全国农村样本点乡站放置和取出宫内节育器年均258.5例次,开展女性绝育术年均38.5例次,实施人工流产术年均29.6例次,三地区间差异有统计学意义(P<0.05)。开展男性绝育术和皮下埋植术年均分别为10.4例次和2.5例次,三地区间差异无统计学意义(P>0.05);在样本点中,95%(737/776)的乡站有B超设备,其中B超服务用于宫内节育器检查和妇科疾病诊断的乡站比例分别为69.5%(509/737)和55.0%(405/737);提供常见妇科疾病诊治、产前检查、不育症诊治的比例分别为84.1%、76.8%和25.4%,提供性病诊治比例为19.5%;提供妊娠试验、血尿便常规检查和宫颈涂片的比例分别为91.4%、18.6%和9.8%。精液检查比例为3.5%;提供短效、长效和速效口服避孕药的比例分别为95.6%、89.7%和71.3%。提供紧急避孕药的比例为24.7%。提供避孕套的比例为97.8%;能提供咨询服务的乡站比例75.6%,设有“悄悄话”室乡站的比例为52.1%;提供术后和产后随访服务的比例分别为85.4%和38.3%。结论全国农村样本点乡站在提供计划生育手术服务、发放避孕药具,以及围绕着生育、节育和不育开展力所能及的生殖保健服务方面已经具备相当能力,但各地的技术服务提供和服务能力发展并不均衡,东、中、西部地区的差别明显。表明我国基层计划生育服务站改革已是一种必然趋势,改革的方向应遵照国家人口计生委关于服务站建设的总体发展格局对乡站进行优化和整合。只有改革才能加快乡站服务能力建设,才能提高服务水平,才能适应客观需求,才能让广大农村育龄群众得到满意的服务。 相似文献

Patent foramen ovale is frequently observed in the general population. In case of massive pulmonary embolism, the sudden increase in the right heart cavity's pressure may cause a right-to-left shunting across this foramen, which could be associated with conflicting outcomes. Herein, we report a case of reversible cardiac arrest preceded by seizures, and followed by hemodynamic stability without any vasopressor. A brain CT-scan showed a limited ischemic stroke. Initial echocardiographic assessment revealed an acute cor pulmonale and a right-to-left intracardiac shunt across a large patent foramen ovale, suggesting the diagnosis of massive pulmonary embolism that was lately confirmed by a multidetector CT-angiography. Anticoagulation therapy was rapidly complicated by a hemorrhagic transformation of the ischemic stroke leading to a fatal outcome. This case illustrates the double-edged circulatory effect of shunting across a patent foramen ovale in case of massive pulmonary embolism: it may have limited circulatory failure but caused in the meanwhile a fatal paradoxical brain embolism. 相似文献

The increased prevalence of atrial fibrillation (AF) has led to specialized AF clinics (AFCs) to facilitate management of AF patients. In this article we report on outpatient AFCs in Canada, which is essential to health policies required to standardize the performance of existing AFCs and help design new AFCs. We surveyed 14 clinics in 5 provinces; 100% provided responses to a detailed questionnaire on clinic processes and care practices. Fourteen care maps were analyzed, and 5 models of care were identified; 4 were specific to AFCs. An online survey with 49 questions included items on: (1) process before visit; (2) process at visit; (3) patient education provided; (4) outreach; and (5) specific clinic information. Clinicians’ advice to patients on self-care items such as: (1) amount of alcohol and (2) caffeine intake; (3) exercise activity; (4) stressful events; (5) “when to go to the emergency department”; and (6) lifestyle changes, were evaluated to assess consistency in practice. There were moderate variances in clinicians’ advice to patients in 5 of 6 self-care items. The 1 item that had 100% consistent practice recommendation was when to go to the emergency department. A guideline-based clinical assessment checklist (CAC) was piloted to obtain feedback on its usability in real-world practice; revisions finalized the “simplified CAC” for AF care encompassing 35 data points with rationale. There was 100% positive feedback on its ability to provide baseline elements in AF care. When validated, a “simplified CAC” can facilitate a standardized clinical assessment tool in clinical practice. 相似文献

The present paper concerns the criteria people would prefer for prioritising health programmes. It differs from most empirical studies as subjects were not asked about their personal preferences for programmes per se. Rather, they were asked about the principles that should guide the choice of programmes. Four different principles were framed as arguments for alternative programmes. The results from population surveys in Australia and Norway suggest that people are least supportive of the principle that decision makers should follow the stated preferences of the public. Rather, respondents expressed more support for decisions based upon health maximisation, equality and urgency. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

The psychosomatic psychotherapeutic consultation liaison (CL)-service for gynecological patients at the Vienna University has been evaluated. Research interest focused on success and failure of the initial interview, conceptualized for a specific clientele. The interview has a triage function for treatment planning. By the type of treatment that was applied, patients were divided into three groups: Group A, patients with one single contact with the unit; Group B, patients who were referred to external psychotherapy; Group C, patients who were treated with short-term psychoanalytic psychotherapy as offered by the service unit. The drop-outs figured as Group D. The questionnaires completed by the patients at the first consultation and 6 months after their final contact with the clinic covered socio-demographic data, ego functions; the motivation for psychotherapy, a complaints list and finally, at the second contact only, an individual retrospective judgement concerning personal consequences of the consultation. Patients needs in CL-seruices call for quick decisions, which therapeutic measure would be most adequate. An experienced clinician's decision is based on several circumstances: individual feeling of suffering therapy-motivation and ego-strength, as well as social and demographic facts. Comparing groups with different therapeutic recommendations showed that the psychometric tests discriminated well between these four groups and thus the validity of the clinical recommendation has been confirmed. 相似文献
