Does Evidence-Based Medicine Help the Development of Clinical Practice Guidelines: Application of clinical recommendationsTo avoid misapplication of clinical recommendations to the wrong patient populations or clinical settings, clinical practice guidelines should clearly state the specific patients and circumstances to which they apply. Appropriate clinical applicability is primarily determined by the scientific and clinical evidence. Guidelines may recommend, for instance, the use of fibrinolytic agents in patients with acute myocardial infarctions but avoid misuse of these agents by explicitly stating exceptions to their use and acceptable alternatives in various clinical settings. buy zyrtec online

What are the goals of this method in shaping the final form of guidelines through the development process? The Institute of Medicine and the Agency for Health Care Policy and Research have described the attributes of clinical practice guidelines that should emerge from a systemic approach to guideline development.
Attributes of Systematically Developed Clinical Practice Guidelines
As drugs should have certain demonstrated safety, efficacy, and pharmacokinetic profiles before they are introduced into clinical practice, so should clinical practice guidelines have attributes that ensure their safety, efficacy, and likelihood of adoption by practicing physicians (Table 1).

Does Evidence-Based Medicine Help the Development of Clinical Practice Guidelines: Promoting Guideline EffectivenessThe second factor that distinguishes clinical practice guidelines from earlier documents that guide clinical practice is a reliance on a formal method that explicitly outlines the guideline’s developmental process. Ideally, clinical practice guidelines provide within their texts documentation of the process by which recommendations emerge from an interaction between scientific data and professional judgment. Much as a methods section in a basic science or clinical research paper provides accountability and reproducibility for the scientific method, the methods section of a clinical practice guideline fulfills the reader’s expectations that the guideline contains more well-constructed and valid recommendations than can be generated through an informal, opinion-based process. This formal method has been emphasized by the Institute of Medicine in its definition of clinical practice guidelines, which are systematically developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances. antibiotics online

This article begins with the bias that all valid patient care guidelines derive more or less from the scientific evidence and that following their recommendations will increase the probability of producing the desired patient outcome. The article ends with the conclusion that concerns about using evidence-based medicine in guideline development result from a less-than-clear understanding of the nature of clinical practice guidelines and evidence-based medicine. These two processes for assisting clinical decision-making are well suited for each other and produce the most valid therapeutic and diagnostic recommendations that are possible at any particular time to ensure high-quality patient care.

Does Evidence-Based Medicine Help the Development of Clinical Practice Guidelines?It would appear at first glance self-evident that good clinical practice would derive its fundamental justification from high-quality investigative evidence. The traditional training of physicians in the scientific method and the pathophysiologic approach to disease management seem to provide an affirmative answer to the question in this article’s title: evidence-based medicine helps the development of clinical practice guidelines, insofar as we would like to think that scientific data drive most physician decisions. canadian pharmacy

But whether recognized or not, the harsh reality of medicine is that many, if not most, daily clinical decisions are not based on valid scientific fact. Despite extensive clinical investigations into the management of pneumonia, for instance, uncertainties remain regarding the ideal antibiotics for community-acquired pneumonia, when to switch patients from IV to oral antibiotics, and the role of diagnostic bronchoscopy with quantitative cultures for patients with suspected ventilator-associated pneumonia.

Our observational cohort study demonstrated that the placement of tracheotomy did achieve its clinical goal, ie, although practically all children with tracheotomies were colonized, they suffered significantly fewer infections (one of four patients). Some physicians may argue that this infection rate of 27% does not justify preventative interventions. Although the main problem was of primary endogenous origin, the exogenous pathway was found to be substantial. The 35% exogenous colonization and infection episodes may be traditionally interpreted as a huge crossinfection problem due to bad nursing practices. However, two observations were highlighted by this study that are in line with previous work in this particular patient population. First, despite high standards of hygiene, maintaining sterility of the lower airways in patients with tracheotomies seems impossible. Second, systemic antibiotics fail to sterilize the lower ainvays in these patients, once they are colonized or infected. Read the rest of this entry »

Impact of Tracheotomy on Colonization and Infection of Lower Airways in Children Requiring Long-term Ventilation: OutcomeThe prophylactic strategy of selective decontamination of the digestive tract (SDD) is based on the classification using the carrier state. The most important feature of SDD is the use of a combination of carefully selected nonabsorbable antimicrobials polymyxin, tobramycin, and amphotericin B These are given topically to the oropharynx and GI tract to prevent or eradicate, if initially present, oropharyngeal and GI carriage of PPMs. It is designed to prevent or minimize the impact of only endogenous, both primary and secondary infections, ie, those preceded by oropharyngeal and GI carriage.
