Risk management. Betting on good information.

Eating potato salad left out in the sun, flying a kite in a rainstorm, sticking a fork in a light socket--we don't need an actuarial table to know that these and many other actions are downright life-threatening. Most of us grow up learning these basic lessons and think of them as common sense, not as a measure of risk. But what about having a heart attack? Contracting a fatal disease? Experiencing unusual side effects from medicine? These risks aren't so obvious. But in each situation, information is available that can identify the chances of any one of us experiencing a stroke or food poisoning. In fact, conclusions about the incidence and potential health risks are key in the daily business decisions of healthcare. Just knowing the gambles, however, is not what risk in healthcare is all about. Instead, it is about the potential costs of those risks to health planners footing the bill.

Validity aspects of erythrocyte sedimentation rate and C-reactive protein in ankylosing spondylitis: a literature review.

The preliminary core set for endpoints in disease controlling antirheumatic therapy includes acute phase reactants. The objective of this clinically oriented literature review was to examine and compare the validity of erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) in ankylosing spondylitis (AS) clinical trials. A MEDLINE search was performed covering the years 1967 through April 1998. AS studies were identified and selected if they included ESR and/or CRP and either presented data about their relation with disease activity or were designed as longitudinal clinical trials. Additional studies were identified by scrutinizing references cited in the retrieved studies. The selected studies were examined for truth (association with disease activity), discriminative power (sensitivity to change and discrimination between active and inactive treatment in longitudinal clinical trials), and feasibility (e.g., applicability and costs) of ESR and CRP in AS. We identified 12 articles on the association of ESR and/or CRP with disease activity and 13 longitudinal clinical trials reporting ESR and/or CRP data. Although the applied definitions or disease activity proved very inhomogenous, there was some evidence that both acute phase reactants are correlated with disease activity. In terms of discriminative capacity the available data are inconclusive. Relevant feasibility aspects are general availability, technically simple measurement, and an advantage in the cost of ESR and central laboratory facilities for CRP. Acute phase reactants do not comprehensively represent the disease process in AS. Their worth in AS clinical trials is limited. Based on the currently existing data neither measure is clearly superior in terms of validity. When selecting an acute phase reactant, feasibility aspects may be most relevant in choice of measure.

[Creating a local collection of professional reports. A stake in the engineering of diploma education and research in continuing education].

The question of the dissertation written during the training is tackled through the entry key offered by the professional dissertations written during the training courses leading to qualification in the framework of a university department of vocational training. 72 professional dissertations, defended between 1993 and 1996, were analysed on the basis of observation sheets filled out by the directors. In reference to the semiotic approach which provides relevant theoretical and methodological materials for the problem posed, we shall show the interest of considering that these documents are, above all, "object-speeches" and must therefore be studied as such. According to the demands to be determined, related to the types of speeches to deliver, the professional dissertations considered as written traces reconstituting the practices and praxis which found them, as well on the professional as on the scientific level, can provide indications for training, in the area of research as well as in the one of praxeology. The written document is thought of as an object of transition from practice to professional praxis, rallying the scientific praxis which is expressed particularly in the writing work.

Discrimination of changes in osteoporosis outcomes.

The purpose of this paper was to identify existing work related to discrimination, responsiveness, and minimal clinically important differences (MCID) for 4 key clinical outcomes in osteoporosis, to serve as a background to discussions about how to define MCID for both individuals and groups. The outcomes assessed were bone density, fractures, quality of life, and function. We conducted a systematic literature search in MEDLINE, EMBASE, and Current Contents for articles that discussed responsiveness, detectable difference, improvement criteria, and clinical importance. We used the Beaton cube to classify the studies depending on whether they compared differences between or changes within individuals or groups. Although a number of studies were identified that presented data on detectable differences beyond error and observed differences, few studies presented data on how to define clinically important differences. A key priority for future research is to define minimally clinical important differences for clinically important osteoporosis outcomes using a consensus based approach that will be accepted by the osteoporosis community at large. Furthermore, these MCID will likely be different for individual patients seen in clinical practice than for individuals in a clinical trial.
