Characterizing cancer information systems.

The objective is to determine the extent to which information systems (IS) for cancer are unique and necessary. Via an analysis of Medical Subject Headings used to index relevant literature and other bibliometric techniques, cancer IS are compared and contrasted with IS of other specialties. Cancer IS are relatively little discussed and primarily connect radiation equipment with the radiation oncology staff. By contrast, clinical laboratory and radiology IS are frequently discussed and connect specialized equipment to the hospital. A "Specialty Need" model accounts for these patterns and says that the "need for a specialty IS" is proportional to the "uniqueness of the specialty tools" plus the "degree to which the information from those tools is needed throughout the particular health care entity".

A case study of a retracted systematic review on interactive health communication applications: impact on media, scientists, and patients.

BACKGROUND: In October 2004, a flawed systematic review entitled "Interactive Health Communication Applications for People with Chronic Disease" was published in the Cochrane Library, accompanied by several press releases in which authors warned the public of the negative health consequences of interactive health communication applications, including the Internet. Within days of the review's publication, scientists identified major coding errors and other methodological problems that invalidated the principal conclusions of the study and led to a retraction. While the original study results and their negative conclusions were widely publicized in the media, the retraction seemed to go unnoticed. OBJECTIVE: This paper aims to document an unprecedented case of misinformation from a Cochrane review and its impact on media, scientists, and patients. As well, it aims to identify the generic factors leading to the incident and suggest remedies. METHODS: This was a qualitative study of the events leading to the retraction of the publication and of the reactions from media, scientists, and patients. This includes a review and content analysis of academic and mass media articles responding to the publication and retraction. Mass media articles were retrieved in May 2005 from LexisNexis Academic and Google and were classified and tallied. The extended case method is employed, and the analysis is also applied to comparable publishing events. RESULTS: A search on LexisNexis Academic database with the query "Elizabeth Murray AND health" for the period of June 2004 to May 2005 revealed a total of 15 press reports, of which only 1 addressed the retraction. Google was searched for references to the review, and the first 200 retrieved hits were analyzed. Of these, 170 pages were not related to the review. Of the remaining 30 pages, 23 (77%) were reports about the original publication that did not mention the retraction, 1 (3%) was a bibliography not mentioning the retraction, and 6 (20%) addressed the retraction, of which only 1 was a non-Cochrane-related source. CONCLUSIONS: Analyzed retrievals showed that the mass media gave more coverage to the Cochrane review than to the retraction or to a related systematic review with a similar scope but a different conclusion. Questionable results were prematurely disseminated, oversimplified, and sensationalized, while the retraction was hardly noticed by the public. Open commentary by scientists and patients helped to rapidly identify the errors but did not prevent or correct the dissemination of misinformation.

Obstructive sleep apnea and head and neck neoplasms.

OBJECTIVE: To elaborate the relationship between obstructive sleep apnea (OSA) and head and neck neoplasms (HNN). STUDY DESIGN AND SETTING: A systematic review of the MEDLINE literature. RESULTS: Thirty of 34 articles indexed under OSA and HNN were about neoplasms that presented first as OSA. Four of the articles were about treatment of HNN causing OSA and gave incidences varying from 8% to 92%. Quality of life surveys confirm that patients with malignant HNN have sleep problems. Xerostomia may contribute to these sleep problems, and the role of salivary mucins deserves consideration. CONCLUSIONS: This review of the literature raises several new research questions about the clinical and biological relationships between OSA and HNN.

The aging of a clinical information system.

The senescence of a clinical information system is more likely to have administrative than technical bases. Supporting this claim is a case study of one aging oncology information system. The case study is qualitative, as behooves the subject matter. Content analysis of several documents suggests that the change in job description of the data coordinator led to a workflow breakdown. Next, twenty-two individuals were interviewed. Notes from the interviews were coded, and the resulting patterns led to partial support for the workflow breakdown conjecture, refutation of the hypothesis that users disliked the character-based, human-computer interface, support of the conjecture that political rather than technical factors drive the usage patterns of the system, and evidence that 'political' activity will determine the future of the information system. A stakeholder matrix is proposed that addresses administrative concerns. Also, the issue of the uniqueness of any oncology clinical information system is linked to the plans for this legacy system.

Comparing HIPAA practices in two multi-hospital systems.

The comparison of HIPAA compliance efforts at two multi-hospital networks (Children's Health System and Carilion Health System) suggests a framework for classifying practices and for facilitating the integration of further case studies into a national library of HIPAA practices.
