In recent years, major and widely accepted information security understandings and achievements confirm that the problem is complex. They clarify that technologies are fundamental tools, but management processes have even bigger relevance, as also prestigious international magazines dossier clearly explained recently. Such a magazine attention outlines the wide impact that the subject has on watchful decision makers. ISO17799 is an emerging standard in information security. In principle there are no reasons for considering it not applicable to the health care sector. In practice, because of both the just conceptual level of the standard and the peculiarities of the health care data and institutions, a lot of analysis and design work need to be invested any time a health care institution decides to deal with the subject. CEN/ENV 12924 is another emerging standard certainly more on the spot of the health care. Nevertheless, it also asks for evident further investigation. The practical case of information security design, implementation, management, and auditing inside a multi-specialty provincial Italian hospital will be described. 相似文献

综合医院内科与中医科门诊抑郁障碍患病率比较 总被引:13,自引:0,他引:13
目的调查沈阳市不同级别综合医院内科和中医科门诊病人抑郁障碍的患病率。方法采用分层随机整群抽样方法抽取沈阳市23家综合医院进行调查,共调查7448例年龄?15岁的内科和中医科门诊病人。调查员在门诊于病人就诊前使用扩展的一般健康问卷(GHQ-12)为筛查工具,将病人分为精神疾病高、中、低危险组,然后由精神科医生使用DSM-Ⅳ定式临床检查(SCID-I/P)对高、中、低危险组100%、40%、10%的调查对象进行SCID诊断。结果沈阳市综合医院内科门诊任何抑郁障碍的总现患率为11.01%(95%CI10.05%-12.06%),中医科抑郁障碍患病率为16.22%(95%CI13.23%-19.87%),高于内科门诊抑郁障碍患病率,RR值为0.68。结论沈阳市综合医院中医科门诊抑郁障碍患病率高于内科门诊,应该更加关注中医科就诊患者的抑郁障碍问题。 相似文献

Both immunoglobulin E (IgE)-mediated food allergy and food intolerance can lead to many changes in personal behaviour and health care resource use which have important economic consequences. These costs will impact directly, indirectly and intangibly on both individuals and society in general. It is important to measure the cost of illness (COI) of food allergy as a first step in developing and evaluating measures to reduce and control the burden of illness. This paper outlines a framework for assessing COI of food allergy from different viewpoints. It offers a structure for identifying the different cost impacts on allergic and nonallergic consumers, food producers and society as a whole, and for scoping, measurement and valuation of relevant costs. Within this structure, the existing literature is reviewed. This review illustrates the lack of information and clear methodology for assessing costs of food allergy. The paper concludes that there is a need for a more structured research programme to generate data essential for future evaluations of procedures and technologies for the diagnosis, treatment and management of food allergy. 相似文献

综合性医院冠心病病人抑郁/焦虑现况研究 总被引:4,自引:2,他引:4
目的:了解综合性医院冠心病患者抑郁和/或焦虑症状患病率及既往诊治情况。方法:采用现况研究方法,于2004年6月1日到12月1日在北京、上海、广州和成都的7家综合性医院的心内科连续收集确诊的冠心病患者359例。由经培训的调查员用统一的调查表进行面对面调查,同时使用综合医院焦虑抑郁量表(HAD)、Hamilton焦虑量表和Hamilton抑郁量表进行心理测评。结果:冠心病患者的抑郁症状、焦虑症状、抑郁合并焦虑症状以及合计的抑郁和/或焦虑症状患病率分别为19.8%,16.7%,13.6%和22.8%;在具有抑郁和/或焦虑症状的非首诊患者中,冠心病患者既往被诊断为抑郁和/或焦虑障碍和接受抗抑郁和/或焦虑治疗的比例均低于4%:住院患者在本次住院期间的抑郁焦虑诊治率低于1%。结论:综合医院冠心病病人具有较高的抑郁和/或焦虑症状和抑郁和/或焦虑障碍患病率.且既往诊治率较低。 相似文献

ObjectivesClinical genomics is emerging as a diagnostic tool in the identification of blood relatives at risk of developing heritable diseases. Our objective was to identify how genetic cascade screening has been incorporated into health economic evaluations.MethodsA scoping review was conducted to identify how multiple generations of a family were included in economic evaluations of clinical genomic sequencing, how many and which relatives were included, and uptake rates. Databases were searched for full economic evaluations of genetic interventions that screened multiple generations of families and were in English language, and no restrictions were made for disease or publication type. Data were synthesized using a narrative approach.ResultsTwenty-five studies were included covering a range of diseases in various countries. Markov cohort models were mostly used with hypothetical populations and unsupported by clinical evidence. Cascade testing was either the primary intervention or secondary to the index cases. The number and type of relatives were based on assumptions or identified through population or family records, clinical registry data, or clinical literature. Studies included only immediate family members and the uptake of testing ranged between 20% and 100%. All interventions were reported as cost-effective, and a higher number of relatives was a key driver.ConclusionsSeveral economic evaluations have considered the impacts of cascade testing interventions within clinical genomics. Ideally, models supported with high-quality clinical data are needed and, in their absence, transparent and justifiable assumptions of uptake rates and choices about including relatives. Consideration of more appropriate modeling types is required. 相似文献
