Since in practice the fixed consulting hours of doctors set limits to the dispersion or flexibility of the work amount cabergoline 0.5mg otc women's health vancouver, we can argue that the more validate and relevant information the practitioners get within constant time to access it the better discount 0.25 mg cabergoline visa breast cancer foundation. A cautious approach to introduce knowledge management issues in clinical applications can be seen as a virtue. For example the fact that an article is published in an academic journal does not guarantee that the information is true. One such article presented findings from a research that demonstrated how sodium fluoride effectively prevents contracting osteoporosis. Later another more validate research findings proved that there truly was causality between these two—only the effect sodium fluoride had on the illness was just the opposite (Slawson & Shaughnessy, 1997). One barrier to the widespread use of knowledge management tools is the psychological need of clinicians. Weinberg, Ullian, Richards, and Cooper (1981) found that 81 American doctors in a distant geographical area consulted 23 experts, logging 11 calls to experts each month. Six of these experts received over 90 percent of the calls, about 90 each a month. The other doctors can also provide the psychological benefits that are not available from books, journals, and computers. On the other hand, the doctors “answering” the questions may sometimes not be much more knowledgeable than the doctors seeking answers. Also a review article by Smith in 1996 which looked at the information needs of general practitioners made several similar conclusions, one of which was that doctors are looking for guidance, psychological support, affirmation, commiseration, sympathy, judgement, and feedback.

Towards Knowledge Intensive Inter-Organizational Systems in Healthcare 281 particularly poorly explored, and yet it may well be the most important need and the biggest stumbling block to a technical solution. The electronic consultation and knowledge management tools, such as decision-support systems, could support each other in various ways. Doctors could use the knowledge system for retrieving required information before referring to the specialist. They could for example check what are the necessary laboratory tests that should be done before referring. Conclusions Within the healthcare sector, different types of process can be identified with different demands on the quality of information and knowledge required. The amount of reference information needed to make a diagnosis differs from one specialization to the next in a hospital. In some fields, the information required by a doctor consists mainly of basic data, observations recorded in numbers and text, whereas in other fields an image or video clip is considered crucial for drawing conclusions. While the significance of what is known as tacit information is important in some fields, in the majority of cases it is explicit information that is required; and it is in care chains relying heavily on explicit information that the potential of information technology can be put to the best use. We examined the impacts on adoption of a new inter-organizational system in healthcare. The consequences from using the Intranet-type referral system in the example case were, first, that the number of patients who were asked to actually visit a specialist was reduced to half thus reducing the burden on specialist resources. According to the doctors involved, this happened in 75 percent of the cases without any observable problems to fulfill the appropriate treatment. However, there were differences between the benefits in different medical areas according to nature of information related to education of different specialists. This should be considered more carefully in the future, when new information systems will be planned and developed. Evidently in internal medicine, specialists make conclusions from pieces of information of symptoms, medical histories and laboratory tests. The information used is explicit, reasonably well structured and treatment is often medication. Intranet referral system both increased the utilization of specialist consultation and decreased the need for secondary care services by transferring information and knowledge to primary care. Because all patients were thoroughly examined beforehand, the numbers of repeat visits as well as direct costs remained lower. In orthopedic surgery the situation appeared to be different, as the diagnostic process is based more on tacit knowledge and the specialist frequently rely on direct observa- tions.

Contractility: The ability of the heart to alter its contractile force and velocity indepen- dent of fiber length cheap 0.5mg cabergoline otc mistral kitchen. In simple terms buy discount cabergoline 0.5 mg women's health hargreaves street bendigo, it represents the intrinsic strength of the individual muscle fiber cells. Contractility can be increased by stimulation of beta-receptors in the heart (see below). Brief Review of the Adrenergic, or Sympathetic Nervous System Cardiac output and its determinants (preload, afterload, and contractility) are all influenced 20 by the adrenergic nervous system. The adrenergic system releases catecholamines (epineph- rine and norepinephrine), which bind to end-organ receptors. These adrenergic receptors are divided into two classes, designated alpha (α) and beta (β), and their actions are summa- rized in Table 20–1. When stimulated, these receptors cause vasoconstriction and increase BP, SVR, and afterload. When activated, these receptors stimulate the SA node to increase the heart rate and increase contractility. Beta-2 Receptors: Found in the peripheral vascular tree as well as in the bronchial wall smooth muscle. Activation causes vasodilation of the peripheral vasculature and bronchodi- latation. These adrenergic receptors are important because many of the cardiovascular drugs used in the ICU act through their sympathomimetic properties. These drugs usually have specific receptor affinity (ie, β versus α) and consequently differ in their effects. Drugs that act on alpha-1 receptors, for example, are called “vasopressors” because they cause vaso- constriction. Drugs that act on beta-1 receptors are conversely called “inotropes” because they increase contractility and heart rate. CENTRAL VENOUS PRESSURE The CVP catheter is one of two major devices used in cardiovascular instrumentation. The other major device, the pulmonary artery catheter (often called the Swan–Ganz catheter), is considered in the next section. This filling pressure de- fines the ability of the right side of the heart to accept and pump blood. Method 20 A 14-gauge intravenous catheter is inserted into the internal jugular or subclavian vein (see Chapter 13). A chest x-ray is required to confirm the position of the catheter in the superior vena cava. The zero point for the manometer is usually 5 cm below the sternal notch, in the midaxillary line. CVP Limitations • CVP does not reflect total blood volume or left ventricular function. TABLE 20–3 Interpretation of CVP Readings Reading (cm H20) Description Implications <4 Low Fluids may be pushed 4–10 Midrange Not clinically useful >10 High Suspect CHF, cor pulmonale, COPD, ten- 20 sion pneumothorax, cardiac tamponade Abbreviations: CVP = central venous pressure; CHF = congestive heart failure; COPD = chronic obstructive pulmonary disease. Technical Tips • If CVP readings do not fluctuate with respiration, the readings are inaccurate. PULMONARY ARTERY CATHETERS The pulmonary artery (PA or Swan–Ganz) catheter is a device that allows the measurement of central circulatory parameters useful in the treatment of the acutely ill patient. The catheter actually passes through the heart; its distal end is in the pulmonary artery (Figure 20–3). It allows the measurement of the pulmonary artery pressure (PAP), the pulmonary artery occlusion pressure (PAOP, also known as the pul- monary capillary wedge pressure, PCWP), the CO, and the CVP. Newer technology also al- lows for the continuous monitoring of mixed venous oxygen saturation (SvO2), measurement of the right ventricular ejection fraction (REF), and the right ventricular end- diastolic volume index (RVEDVI). Indications Common clinical conditions requiring PA catheter monitoring include: • Acute heart failure • Complex circulatory and fluid conditions (massive resuscitation) • Shock states • Diagnosis of pericardial tamponade • Intraoperative management (aneurysm repair, elderly patient undergoing major surgery) • Complicated MI Catheter Description The original PA catheter, still commonly called the Swan–Ganz catheter after its inventors, consists of three lumens and a thermistor at the tip (Figure 20–4).
