In this article, tragedy and utopia are juxtaposed, and it is proposed that the problem of "medicalisation" is better understood in a framework of tragedy than in a utopian one. In utopia, it is presupposed that there is an error behind every setback and every side effect, whereas tragedy brings to light how side effects can be the result of irreconcilable conflicts. Medicalisation is to some extent the result of such a tragic conflict. We are given power by medical progress, but are also confronted with our fallibility, thus provoking insecurity. This situation is illustrated by the sudden infant death syndrome (SIDS). Recent epidemiological investigations have shown that infants sleeping in a prone position have a 15-20 times higher risk of dying from SIDS than infants sleeping in a supine position. A simple means of preventing infant death is suggested by this discovery, but insecurity is also created. What else has been overlooked? Perhaps a draught, or wet diapers, or clothes of wool are just as dangerous as sleeping prone? Further investigations and precautions will be needed, but medicalisation prevails. (+info)
Reducing unnecessary inpatient laboratory testing in a teaching hospital.
(58/227)
After an inpatient phlebotomy-laboratory test request audit for 2 general inpatient wards identified 5 tests commonly ordered on a recurring basis, a multidisciplinary committee developed a proposal to minimize unnecessary phlebotomies and laboratory tests by reconfiguring the electronic order function to limit phlebotomy-laboratory test requests to occur singly or to recur within one 24-hour window. The proposal was implemented in June 2003. Comparison of fiscal year volume data from before (2002-2003) and after (2003-2004) implementation revealed 72,639 (12.0%) fewer inpatient tests, of which 41,765 (57.5%) were related directly to decreases in the 5 tests frequently ordered on a recurring basis. Because the electronic order function changes did not completely eliminate unnecessary testing, we concluded that the decrease in inpatient testing represented a minimum amount of unnecessary inpatient laboratory tests. We also observed 17,207 (21.4%) fewer inpatient phlebotomies, a decrease sustained in fiscal year 20042005. Labor savings allowed us to redirect phlebotomists to our understaffed outpatient phlebotomy service. (+info)
Transhumanism, medical technology and slippery slopes.
(59/227)
In this article, transhumanism is considered to be a quasi-medical ideology that seeks to promote a variety of therapeutic and human-enhancing aims. Moderate conceptions are distinguished from strong conceptions of transhumanism and the strong conceptions were found to be more problematic than the moderate ones. A particular critique of Bostrom's defence of transhumanism is presented. Various forms of slippery slope arguments that may be used for and against transhumanism are discussed and one particular criticism, moral arbitrariness, that undermines both weak and strong transhumanism is highlighted.

EAE laboratory standards and accreditation.
(60/227)
Laboratory standards have been set by the European Association of Echocardiography of the European Society of Cardiology, in order to homogenize the practice of echocardiography in Europe and therefore ultimately, to protect patients. These standards have been developed for transthoracic, transesophageal and stress Echocardiography into two levels; the basic level, set to provide basic laboratory standards for an optimal clinical service and the advanced level, which is set to establish a fewer number of advanced laboratories in each country, where by in addition to basic standards, they may be providing extensive teaching and research.

Applying research evidence to optimize telehomecare.
(61/227)
Telemedicine is the use of technology to provide healthcare over a distance. Telehomecare, a form of telemedicine based in the patient's home, is a communication and clinical information system that enables the interaction of voice, video, and health-related data using ordinary telephone lines. Most home care agencies are adopting telehomecare to assist with the care of the growing population of chronically ill adults. This article presents a summary and critique of the published empirical evidence about the effects of telehomecare on older adult patients with chronic illness. The knowledge gained will be applied in a discussion regarding telehomecare optimization and areas for future research. The referenced literature in PubMed, MEDLINE, CDSR, ACP Journal Club, DARE, CCTR, and CINAHL databases was searched for the years 1995-2005 using the keywords "telehomecare" and "telemedicine," and limited to primary research and studies in English. Approximately 40 articles were reviewed. Articles were selected if telehealth technology with peripheral medical devices was used to deliver home care for adult patients with chronic illness. Studies where the intervention consisted of only telephone calls or did not involve video or in-person nurse contact in the home were excluded. Nineteen studies described the effects of telehomecare on adult patients, chronic illness outcomes, providers, and costs of care. Patients and providers were accepting of the technology and it appears to have positive effects on chronic illness outcomes such as self-management, rehospitalizations, and length of stay. Overall, due to savings from healthcare utilization and travel, telehomecare appears to reduce healthcare costs. Generally, studies have small sample sizes with diverse types and doses of telehomecare intervention for a select few chronic illnesses; most commonly heart failure. Very few published studies have explored the cost or quality implications since the change in home care reimbursement to prospective payment. Further research is needed to clarify how telehomecare can be used to maximize its benefits among diverse adult chronic illness populations. (+info)
Validation of a method for predicting the precision, limit of detection and range of quantitation in competitive ELISA.
(62/227)
The mathematical model for predicting the precision, limit of detection (LOD) and range of quantitation (ROQ) in a competitive enzyme-linked immunosorbent assay (ELISA) proposed by Hayashi et al. (Anal. Chem., 2004, 76, 1295) was validated. The model describes the relative standard deviation (RSD) of concentration estimates by the RSDs of pipetting volumes of analyte, enzyme-conjugated antigen, antibody and substrate solutions, and the standard deviation (SD) of inherent absorbances between the wells in an ELISA plate. For 6 kinds of direct competitive ELISA kits, the LOD and ROQ predicted by the model agreed well with those obtained by experiments with real samples. It was also confirmed that the model is applicable to the prediction of uncertainty that depends on the pipetting error of the viscous antiserum solution. The model was demonstrated to be useful for estimating the LOD and ROQ of competitive ELISA. (+info)
Giving everyone the health of the educated: an examination of whether social change would save more lives than medical advances.
(63/227)
OBJECTIVES: Social determinants of health, such as inadequate education, contribute greatly to mortality rates. We examined whether correcting the social conditions that account for excess deaths among individuals with inadequate education might save more lives than medical advances (e.g., new drugs and devices). METHODS: Using US vital statistics data for 1996 through 2002, we applied indirect standardization techniques to estimate the maximum number of averted deaths attributable to medical advances and the number of deaths that would have been averted if mortality rates among adults with lesser education had been the same as those among college-educated adults. RESULTS: Medical advances averted a maximum of 178193 deaths during the study period. Correcting disparities in education-associated mortality rates would have saved 1369335 lives during the same period, a ratio of 8:1. CONCLUSIONS: Higher mortality rates among individuals with inadequate education reflect a complex causal pathway and the influence of confounding variables. Formidable efforts at social change would be necessary to eliminate disparities, but the changes would save more lives than would society's current heavy investment in medical advances. Spending large sums of money on such advances at the expense of social change may be jeopardizing public health. (+info)
Rapid detection of group A streptococci: comparative performance by nurses and laboratory technologists in pediatric satellite laboratories using three test kits.
(64/227)
Rapid tests for detecting group A streptococci in throat swabs are often performed outside hospitals or commercial laboratories by individuals with little or no technical training. We compared the abilities of nurses and technologists to perform and interpret three commercial kits (Directigen 1-2-3, ICON Strep A, and Culturette Brand 10-Minute Strep A ID) in three hospital satellite locations (the emergency department, a walk-in emergency clinic, and a general pediatric clinic). When the three tests were compared with culture, the sensitivities of the tests as performed by nurses and technologists, respectively, were 39 versus 44% for Directigen, 55 versus 51% for Culturette, and 72 versus 39% for ICON. A significant difference in sensitivity was found only with ICON tests. This result was largely explained by the tendency of technologists to test moist swabs, while nurses generally processed dry swabs; ICON test sensitivity was significantly greater with dry swabs. The specificities of Directigen and ICON tests performed by nurses and technologists were high (97 to 100%). The difference in the specificities of the Culturette test as determined from results obtained by nurses and technologists (80 versus 98%) was due to the tendency of one nurse to overinterpret the latex agglutination reaction. Analysis of the accuracies of the tests during practice periods compared with the accuracies of the tests during the study periods revealed statistically significant improvement in test performance. We conclude that these tests are specific but not sensitive when performed by nurses and technologists in satellite laboratories. With one exception, nurses and technologists performed the tests with comparable accuracy after brief training periods. (+info)
