To telemedically err is human.

BACKGROUND: As telemedicine alters the process of health care and introduces new technology, the extent to which it introduces new errors or allows for the occurrence of familiar errors needs to be examined. TELEMEDICINE'S IMPACT ON PATIENT SAFETY FEATURES OF TRADITIONAL CARE: The accuracy of diagnostic decisions reached via telemedicine can be directly affected by the technology's limitations and the care providers' lack of training. Telemedicine could increase the risk of familiar types of patient-provider communication failure and introduce the possibility of cumulative errors. TELEMEDICINE'S IMPACT ON NEW CARE FEATURES AND CONCEPTS: Telemedical applications that use the Internet to enhance disease management and detection and monitoring of symptoms may place the privacy and confidentiality of individual health information at risk, which imposes a possible barrier to communication. In addition, home care patients' functional limitations need to be addressed by human factors engineering. RECOMMENDATIONS: Patient safety should be integrated in organizational readiness and budget planning for telemedical interventions in hospitals, academic settings, nursing homes, home care agencies, and other health care settings. Specific recommendations are proposed for the development and diffusion of standards in telemedical care, risk management and reduction, and continuous quality improvement. SUMMARY AND CONCLUSIONS: To address patient safety and provide high-quality care, a framework for addressing and examining telemedical errors needs to be established.

Assessing patient safety awareness and needs in rural hospitals in one US state.

Several initiatives have addressed patient safety by enabling electronic voluntary reporting of adverse events within academic medical centres in urban settings. Such initiatives are lacking in the rural context, and it remains unknown whether the same challenges and solutions apply to rural hospitals. The purpose of this study is to provide insight into the organisational culture and level of readiness to adopt patient safety strategies in a rural setting, as well as to identify critical issues pertaining to the rural context that need to inform the design of such strategies. We conducted telephone interviews with administrators and healthcare providers of rural hospitals in one US state. Questions referred to the respondents' current reporting mechanism, its advantages and disadvantages, and organisational patient safety culture. A total of 16 administrators and 14 providers of eight rural hospitals in the state of Missouri were interviewed. Findings indicate that very few administrators felt that there was a timely response to adverse event reports. Half of the administrators stated that the current mechanism is an appropriate and adequate outlet to ensure patient safety. None of the healthcare providers found errors and adverse events to be over-reported; the majority believe that they are being under-reported. Only 36% of the care providers interviewed have themselves reported an error or adverse drug event during their tenure with their organisation. The study findings demonstrate a definite need for improvement of the current infrastructure of rural hospitals in order to enable an effective outlet for ensuring patient safety.

Evidence-based retrieval in evidence-based medicine.

OBJECTIVE: Clinical decisions based on a meta-analysis that is based on an ineffective retrieval strategy may have serious negative consequences for patients. The study objective was to investigate the extent to which meta-analyses report proof of their retrieval strategies' effectiveness. METHODS: The authors examined a random sample (n = 100) of articles in the 1996 to 2002 full-text subset of Ovid MEDLINE indexed as "meta-analysis." We classified the articles in three ways: the article (A) reported both a retrieval strategy in sufficient detail (such that it could be repeated) and with evidence of the strategy's effectiveness, (B) reported a retrieval strategy in sufficient detail but not with evidence of the strategy's effectiveness, or (C) neither reported a strategy in detail nor evidence of the strategy's effectiveness. Articles classified as (A) were further classified according to the level of evidence reported. RESULTS: Of the eighty-nine articles in our final analysis, six (6.7%) were classified as category (A), fifty-seven (64%) as (B), and twenty-six (29%) as (C). Articles in category (A) reported a previously validated search, a published strategy, or strategy based on expert opinion. CONCLUSION: Peer-review standards must be developed that require authors of meta-analyses to report evidence for the effectiveness of their retrieval strategies.

Differences in the effects of filters on health information retrieval from the Internet in three languages from three countries: a comparative study.

We selected twenty search terms on woman's health from various sources and tested them on Google, once with strict filter on and once with filter off. Searches were specified to three countries (Mainland China, Germany, USA), in three languages (Simplified Chinese, German, US English). We found that the proportion of relevant women's health web sites that were blocked was quite high. For the Chinese language web sites originated in China, 72.6% of the blocked web sites were relevant. For the German language web sites originated in Germany, nearly half (49.4%) were relevant. For the US English web sites originated in the US, 95% were relevant. We concluded that people might unknowingly miss potentially important health information due to information filtering.

Evidence-based retrieval in E-health.

In this chapter we address the issue of standards for information retrieval to support decision making in e-health. Specifically, we consider the issue of evidence-based retrieval in the e-health domains of the consumer, healthcare practitioner, healthcare researcher, and genomics researcher. We present the results of a preliminary study to assess the current state of evidence-based retrieval in e-health. Within this study, we reviewed articles in e-health and telemedicine to determine the extent to which authors provide details of the information retrieval strategies used, as well as evidence of the effectiveness of those strategies. We also examined the extent to which the associated journals require authors of reviews to explicitly provide details of information retrieval strategies that they used, as well as reporting any evidence for the effectiveness of those strategies.

Design and evaluation of SchoolhealthLink, a Web-based health information resource.

SchoolhealthLink, a Web-based information service for Missouri school nurses, is a promising resource to reach school nurses isolated from traditional professional networks. It also may serve as an important adjunct to stay abreast of the latest health information. Using a strategy to identify the health information needs of school nurses and to test the site early in its development, this pilot study found school nurses reported SchoolhealthLink was an easy-to-use method to find high-quality, up-to-date information relevant to school nursing practice, was better than existing methods to access information, and could change the way they practiced. In order to continue to build SchoolhealthLink, a partnership with Barnes College of Nursing and the Missouri Association of School Nurses has been established to work together to continue to add health information resources useful to school nursing practice.

A prototype system for retrieval of gene functional information.

Microarrays allow researchers to gather data about the expression patterns of thousands of genes simultaneously. Statistical analysis can reveal which genes show statistically significant results. Making biological sense of those results requires the retrieval of functional information about the genes thus identified, typically a manual gene-by-gene retrieval of information from various on-line databases. For experiments generating thousands of genes of interest, retrieval of functional information can become a significant bottleneck. To address this issue, we are currently developing a prototype system to automate the process of retrieval of functional information from multiple on-line sources.

Physician PDA use and the HIPAA Privacy Rule.

Physicians need better access to information when making patient care decisions. Hospitals should allow electronic data transfers to physician PDAs to improve patient care, and physicians must institute measures to secure the confidentiality of patient information on their PDAs. By explicitly excluding copies from their designated record set, hospitals need not maintain copies or track access of information on personally owned PDAs.

Using description logic to manage question corpora.

If clinical questions are to be used on a large scale as a practitioner interface to the medical knowledge base, improved methods must be developed for the semantic management of question corpora. In this project we investigate the use of description logic to manage question corpora. We propose the addition of a Q-box to a standard Description Logic knowledge base. The Q-box will contain concept descriptions that are not yet accepted as part of the T-box, but in effect represent questions about concepts already described in the T-box.

Marginalization and health geomatics.

Marginalized groups have been defined as groups that have been peripheralized from the center of society. Increasing nursing knowledge of marginalized groups and the dynamics of population diversity will enable nurses to better recognize shifting health patterns, plan for utilization of health services, and determine ethnic and cultural differences that exist in marginalized populations. The authors of this article review theoretical models responsible for defining the concept marginalization, describe geographical information systems as a recommended tool to evaluate marginalized groups, and provide a case study utilizing tools and maps as a means of assessing marginal situations.
