Background : Patients' desire for information about anaesthesia has been examined in a number of Commonwealth countries but not in Scandinavia. A questionnaire was distributed to form a basis for giving Danish patients more appropriate preoperative information.
Methods : 201 preoperative patients in Denmark were asked to complete a questionnaire. The patients were divided into subgroups according to: age, gender, residential origin, ASA group, educational level, type of anaesthesia planned and number of previous anaesthetics.
Results : Patients from a city area required significantly more information than patients from a rural/urban area about pre-medication drugs, drips/catheters, pain/pain relief and complications. Men more than women preferred to know about dangerous complications. Information about pain /pain relief, duration of anaesthesia, and influence of anaesthesia on daily activities such as eating, drinking, mobilisation was given the highest priority, while unpleasant information such as about complications and needles was given the lowest priority. Meeting the anaesthetist and information about alternative methods of anaesthesia and premedication drugs were given only moderate priority. Ranking information in Denmark was significantly correlated with Scotland, Canada and Australia, despite profound differences in priority. More often than Danish patients, Australian patients felt they had right to know, and especially about complications.
Conclusion : Patients from a city area required more information than patients from a rural/urban area. Information about the influence on daily activities was preferred to unpleasant information. Ranking information in Denmark was correlated with a number of Commonwealth countries. 相似文献

During the years 1959 to 1983 a doubling in the rate of homicide took place in Copenhagen. This increase was exclusively due to an increasing number of male offenders. By comparing with another Danish material, the frequency of female homicide as well as that of homicide combined with suicide was found practically unchanged since 1946, indicating that both of these kinds of homicides seem to have a background different from those of other offences of fatal violence. During the years 1959 to 1983, the criteria of selection of the defendants for a psychiatric examination for the court were fairly consistent. Examinations were performed in practically all cases, where a charge of murder raised by the police was followed by a legal trial for homicide. Less and less of the defendants, however, were hospitalized for the examination, while more were examined in The Clinic of Forensic Psychiatry in Copenhagen. 相似文献

OBJECTIVE: To assess the capacity of textword queries to provide a comprehensive listing of articles on injury prevention and safety promotion (IPSP) concepts in a literature database. METHODS: All terms used to search SafetyLit (a database of scholarly literature selected for its relevance to the IPSP field) during the years 2000-2005 were listed and then examined to identify terms that are synonyms for the same concept. Terms were grouped by concept, the number of queries that used terms within each concept category were summed, and the concepts were then ordered by the total number of searches for each concept category. For each textword, the proportion of all articles for that concept that could be found by using it alone was calculated. RESULTS: Each of the 25 most searched-for concepts has 4 to 40 synonyms. Sixteen of the concepts required queries using two or more terms to find 75% of the available articles. Few searchers used a sufficient number of textword synonyms in their queries to return a complete listing of the available material. CONCLUSION: On the basis of this study, queries using only one or two textword terms are insufficiently sensitive to find all relevant journal articles about an IPSP concept. 相似文献

During the past 10–15 years, Regional Health Care Networks (RHCN) have been established in many regions throughout the world. RHCN build on well-known techniques, methodologies and appropriate standards. Most of the European Countries today have set up IT strategic plans that focus on the establishment of RHCN. The benefits of having access to all relevant information are tremendous and contribute to cost-effective and coherent health services. By the rapid spread and use of Internet, technology has made it possible to interconnect all kinds of applications. In 2000, the most experienced regions in Europe joined PICNIC, a European project to develop the Next Generation Regional Health Care Networks and to support their new ways of providing health and social care. The previous generation of Regional Health Care Networks supported the interconnection of applications by transfer of messages. Messaging is an effective means of integration for isolated high-specialised systems that only need to exchange data. This service will continue to be one of the most important services in the future health care networks. However, tighter coupling may be desirable in some instances to avoid replicating the same functionality in several applications. In other words, certain services can be common and used by a number of applications instead of building that service inside each application. These common services are called middleware services. In PICNIC (http://www.medcom.dk/picnic), a new middleware Collaboration IT service has been identified and developed. This service allows the end users to perform real-time clinical collaboration, with exchange of text, structured data, voice and images across the limits of a single region. A clinical collaboration is associated with the shared clinical context to provide a record of relevant clinical information and facilitates synchronous as well as asynchronous collaboration. This new IT service builds on the increasing popularity of instance messaging and presence systems that facilitate smooth transition between synchronous and asynchronous interaction. The new Collaboration IT service is expected to have a strong impact on the practice of health care in the next generation of Regional Health Care Networks. 相似文献
