Mass psychogenic illness attributed to toxic exposure at a high school.

BACKGROUND AND METHODS: Mass psychogenic illness may be difficult to differentiate from illness caused by bioterrorism, rapidly spreading infection, or toxic substances. We investigated symptoms attributed to exposure to toxic gas at a high school in Tennessee. In November 1998, a teacher noticed a 'gasoline-like' smell in her classroom, and soon thereafter she had a headache, nausea, shortness of breath, and dizziness. The school was evacuated, and 80 students and 19 staff members went to the emergency room at the local hospital; 38 persons were hospitalized overnight. Five days later, after the school had reopened, another 71 persons went to the emergency room. An extensive investigation was performed by several government agencies. RESULTS: We were unable to find a medical or environmental explanation for the reported illnesses. The persons who reported symptoms on the first day came from 36 classrooms scattered throughout the school. The most frequent symptoms (in this group and the group of people who reported symptoms five days later) were headache, dizziness, nausea, and drowsiness. Blood and urine specimens showed no evidence of carbon monoxide, volatile organic compounds, pesticides, polychlorinated biphenyls, paraquat, or mercury. There was no evidence of toxic compounds in the environment. A questionnaire administered a month later showed that the reported symptoms were significantly associated with female sex, seeing another ill person, knowing that a classmate was ill, and reporting an unusual odor at the school. CONCLUSIONS: The illness attributed to toxic exposure had features of mass psychogenic illness - notably, widespread subjective symptoms thought to be associated with environmental exposure to a toxic substance in the absence of objective evidence of an environmental cause. Alleviation of the anxiety surrounding an episode of mass psychogenic illness requires prompt recognition and a detailed investigation.

Collaboration in cancer nursing practice.

Although nursing represents around half of Europe's healthcare budgets, its impact is seldom evaluated. However, given the current era of cost-containment, nursing must prove the value of its clinical effectiveness. Through European collaboration, the WISECARE project is working towards identifying the unique contribution of cancer nursing. This paper will explain the rationale and goals of the WISECARE project and demonstrate the collaborative processes involved within such a project. The latest results of the project will be presented to prove the value of collaboration in ensuring the development of European standards of nursing care.

Multicentre research and the WISECARE experience. Workflow Information Systems for European Nursing Care.

The benefits of collaborative research are becoming recognized increasingly within the profession of nursing due to the associated increased likelihood of funding, variety of practice settings and increased access to resources that collaboration brings. While such benefits have made collaborative research one of the most desirable strategies for achieving the goals of research, the potential problems of language and communication, culturally sensitive instruments, access to subjects, availability of technology and lack of research resources have complicated collaborative international research initiatives. Review of the literature, although encouraging such initiatives, does little to provide information regarding the processes involved in multinational collaboration or the associated advantages and disadvantages to guide those embarking on such large scale, multinational, cross-cultural studies. The diverse meanings of collaboration within research initiatives further hamper this understanding. Positive definitions focus on aspects such as sharing expertise, making a valuable contribution to the research and ultimately shared ownership of the accomplishments of the research. One such research project led by nurses was the WISECARE project. WISECARE (Workflow Information Systems for European Nursing Care) was funded by the European Commission and aimed to improve cancer nursing practice and ultimately patient outcomes through the integration and utilization of state of the art information technology. Such a project was developed as a result of nursing's apparent invisibility within health care delivery and the problems experienced by nurses in articulating their worth within an increasingly cost-conscious health care system. Oncology care was selected as the domain for the project not only because this speciality of nursing already has an established network of nurses throughout Europe in the European Oncology Nursing Society (EONS) but also because the practice of cancer nursing encompasses all aspects of nursing care. This paper will address the advantages and disadvantages associated with collaboration, using the WISECARE project as an example.

An outbreak involving extensive transmission of a virulent strain of Mycobacterium tuberculosis.

BACKGROUND AND METHODS: From 1994 to 1996, there was a large outbreak of tuberculosis in a small, rural community with a population at low risk for tuberculosis. Twenty-one patients with tuberculosis (15 with positive cultures) were identified; the DNA fingerprints of the 13 isolates available for testing were identical. To determine the extent of transmission, we investigated both the close and casual contacts of the patients. Using a mouse model, we also studied the virulence of the strain of Mycobacterium tuberculosis that caused the outbreak. RESULTS: The index patient, in whom tuberculosis was diagnosed in 1995; the source patient, in whom the disease was diagnosed in 1994; and a patient in whom the disease was diagnosed in 1996 infected the other 18 persons. In five, active disease developed after only brief, casual exposure. There was extensive transmission from the three patients to both close and casual contacts. Of the 429 contacts, 311 (72 percent) had positive skin tests, including 81 [corrected] with documented skin-test conversions. Mice infected with the virulent Erdman strain of M. tuberculosis had approximately 1000 bacilli per lung after 10 days and about 10,000 bacilli per lung after 20 days. In contrast, mice infected with the strain involved in the outbreak had about 10,000 bacilli per lung after 10 days and about 10 million bacilli per lung after 20 days. CONCLUSIONS: In this outbreak of tuberculosis, the growth characteristics of the strain involved greatly exceeded those of other clinical isolates of M. tuberculosis. The extensive transmission of tuberculosis may have been due to the increased virulence of the strain rather than to environmental factors or patient characteristics.

The WISECARE Project and the impact of information technology on nursing knowledge.

The European Union retained the WISECARE project "Work flow Information Systems for European nursing CARE" for funding. The project focuses on the use of telematics technology for clinical and resource management in oncology care in hospitals. This paper outlines the impact of introducing this kind of advanced nursing informatics application on the management of nursing knowledge. Three shift in knowledge management that will get high attention in WISECARE, are identified. The first is the shift from knowledge dissemination to knowledge sharing. The second is the shift from individual knowledge to organisational knowledge. The third is the shift from deductive, prescriptive knowledge as seen in guidelines, protocols to more inductive, experience based knowledge. The paper emphasizes that the real impact of information technology is not in the automation of existing processes but on the discovery of new ways of organisation and living.

Standards for nursing terminology.

Terminology work in nursing has given rise to an increasing number of nursing terminologies. These generally take the form of controlled vocabularies. Because of the limitations of the controlled vocabulary approach, individual terminologies tend to be tuned to meet the specific needs of their intended users. Differences between terminologies are now a significant barrier to the comparison and interchange of health information. To agree on a single, multipurpose terminology would be problematic. However, several options for resolving unnecessary differences between nursing terminologies are currently being explored by international standards bodies and other groups, such as the U.S. Nursing Vocabulary Summit. One such option is the use of a terminology model to facilitate evolution toward a more coherent range of terminologies. The authors describe the motivation behind the development of a standard for nursing terminologies. They explain how a terminology model might form the basis for such a standard through a description of the approach taken by CEN TC251 (the Health Informatics Technical Committee of the European Committee for Standardization). They also discuss possible limitations of standardization.
