Reading research articles can be challenging, but it also can be stimulating. Once you get a system for reviewing articles and interpreting their worth and value to your practice, you will find much usable information. Reviewing articles with the focus of assessing their importance to clinical practice could be done with a research committee of your local AORN chapter. It also would be an interesting and informational chapter program to have a panel discuss the relevance of two or three studies to perioperative practice. This process and type of information also can be used if your institution is developing research teams. Assessing the practicality of research to your practice is essential. Research is not a mystery; it is the answer to a mystery. It is necessary to the future of perioperative nursing. Change practice with empirical evidence!
Nursing is a practice-based discipline, with clinical practice forming the heart of any programme of study. The major goal of all programmes should be on facilitating students to develop the skills necessary for competent and compassionate practice. Assessment of clinical competence is a fundamental aspect of programme development and as such deserves attention during the curriculum design process. The literature on assessment of students in clinical practice suggests that the tools used have evolved through various stages, ranging from the use of simple check list and rating scale to the development of competence assessment tools. Each stage has been fraught with difficulties and has taxed nurse educators, clinical assessors and students alike. The literature also indicates that there is a limited range of research available on clinical assessment tools, especially with an intensive care context. In part one of this two-part paper, the literature on assessment of clinical practice is explored, with specific emphasis on the assessment of competence with the Intensive Care environment. Part two of the paper reports on the findings of a study on students perceptions on a clinical competence assessment tool, used in an Intensive Care environment.
This article presents charts from The American Psychiatric Association Practice Guideline for the Assessment and Treatment of Patients with Suicidal Behaviors, part of the Practice Guidelines for the Treatment of Psychiatric Disorders Compendium, and a summary of the assessment information in a format that can be used in routine clinical practice. Four steps in the assessment process are presented: the use of a thorough psychiatric examination to obtain information about the patient's current presentation, history, diagnosis, and to recognize suicide risk factors therein; the necessity of asking very specific questions about suicidal ideation, intent, plans, and attempts; the process of making an estimation of the patient's level of suicide risk is explained; and the use of modifiable risk and protective factors as the basis for treatment planning is demonstrated. Case reports are used to clarify use of each step in this process.
Coping has been defined as an effort to manage external and internal demands and conflicts that tax or exceed a person's resources. This paper examines the types of coping strategies used by two groups of persistent pain sufferers: one from a family practice clinic and the other from a specialty pain clinic. The relationship between the use of different types of coping strategies and adjustment was determined. The two study groups of persistent pain sufferers differed significantly from each other on many of the indices developed to tap adjustment but did not differ on any of the Billings and Moos original categories of coping strategies. When a factor analysis of coping items was performed, 5 valid clusters relevant to the chronic pain patient samples were determined. The factor the authors entitled 'adversarialness' with the qualities of dysphoric withdrawal, avoidant behavior and catastrophizing was found to explain adjustment defined by several indices. The authors conclude that it may be important to help persistent pain sufferers to alter their attitudes and behavior that tend toward catastrophizing, avoidance and withdrawal, rather than simply concentrate on trying to teach them techniques for 'coping with stress.'
BACKGROUND: Effective clinical practice guidelines should improve clinical outcomes, and measures of physician use of clinical practice guidelines should correlate with improved outcomes. This study translates a clinical practice guideline on heart failure into review criteria to measure physician performance and the effectiveness of the clinical practice guideline. METHODS: A panel of 11 family physicians and 1 cardiologist systematically reviewed the clinical practice guideline for its clinical importance, educational relevance, and evaluative appropriateness. Then a subset of 4 family physicians rigorously applied each recommendation to established criteria for measurability and developed an evaluation tool useful in medical record review. RESULTS: The heart failure clinical practice guideline was found to be an excellent educational tool. Using it to measure physician performance, however, was limited to diagnostic tests and drug prescribing. Of 45 recommendations, 5 fulfilled criteria for measurability; 1 recommendation had A-level evidence, whereas 2 recommendations had B-level and 2 had C-level evidence. CONCLUSION: This study illustrates the logistic issues and challenges in developing a measure of physician adherence to clinical practice guidelines. Medical record review is inadequate to measure many recommendations. Physicians use of this clinical practice guideline must be evaluated as an intermediate step to measuring the effectiveness of clinical practice guidelines based on patient outcomes.
BACKGROUND: Zafirlukast is an oral leukotriene receptor antagonist used in the treatment of patients with mild to moderate asthma. To investigate its effects in a clinical practice setting, we evaluated zafirlukast in a heterogeneous group of patients who had asthma of different degrees of severity and who were receiving concomitant asthma medications. METHODS: A total of 3759 patients were enrolled at 924 sites. Patients received zafirlukast 20 mg twice a day for 4 weeks. Pulmonary function was measured twice a day, and overall asthma symptom scores, number of nighttime awakenings, severity of morning asthma symptoms, and beta2-agonist use were recorded daily. RESULTS: In the efficacy analysis (3207 evaluable patients), all parameters showed statistically significant improvement that continued throughout the 4 weeks of the trial. A total of 71% of patients had improved pulmonary function and 72% had improved asthma symptoms. Improvement was consistent regardless of asthma severity category and regardless of concomitant asthma medication category. More than 70% of both physicians and patients indicated there was clinical improvement in pulmonary measures as well as in asthma symptoms. Common adverse events reported were headache (3.7%), nausea (1.4%), pharyngitis (1.4%), and sinusitis (1.1%). CONCLUSIONS: Zafirlukast 20 mg twice a day is well tolerated and improves pulmonary function and asthma symptoms, regardless of asthma severity category and regardless of concomitant asthma medication category.
Clinical decisions in daily practice, to resolve patient's problem, are usually based at the conscious use of the available information, through explicit determined rules. Evidence based clinical practice recognize the explicit and tacit knowledge, understanding that it is impossible all the aspects of professional competence become explicit. The doubt becomes part of the decision process, identifying initially the unconscious component involved and after the explicit knowledge used. When we make a structured clinical question with a possible answer, it is necessary to remember that the doubt can be related to basics and of definition aspects of the disease or related to the patient's manager, like diagnose, treatment and prognosis. Along our medical life, both types of question are present, with proportional change as the experience increase along the clinical practice. The process to find an appropriate answer to the doubt, came out at patient's care, depends on how the parts of this process will be structured. The recommended form is known by PICO abbreviation, that means: P: patient or population, I: intervention or indicator, C: comparison or control and O: outcome, or the answer expected found at the scientific information bases. This is the first basic need to a successful search, and the second need is to find the key words that better describe each of the four components of the questions. Without this caution, the search at compute databases results in absence of information or in a lot of information that it is not related to our interest.
Evidence-based clinical practice requires the development and refinement of literature searching, appraisal skills, and clinical experience. Answering clinical questions using evidence-based methods can be time-intensive, but as one becomes more familiar with the methods, it becomes a fairly straightforward process. For example, it took less than an hour to complete the initial steps of this exercise and arrive at an initial recommendation for Ms. J. Oftentimes, the clinician does not have an hour to find an answer. Fortunately, there are more and more resources available that summarize reviews of clinical questions, so individual practitioners can rapidly access the information they need. Recently, I saw a patient who presented with a preauricular mass. During the visit, a pathologist performed a fine needle aspiration (FNA) to obtain a specimen for diagnosis. Much to our surprise, the FNA results suggested a diagnosis of melanoma. Not being a melanoma expert, I signed on to the computer, went to Up To Date, searched using the keyword "melanoma," and found the information I needed in under a minute. Before the patient left our office, he was scheduled for all the tests and imaging studies needed to maximize his initial appointment with the melanoma specialist. Central to evidence-based clinical practice is the explicit enumeration and balancing of risks and benefits. Evidence is never enough for making clinical decisions. We need to integrate our clinical values and preferences with the patient's values and preferences to render compassionate, informed treatment decisions.
Extrapolation of clinical trial results to clinical practice requires consideration of whether the trial patients were representative of clinical practice, whether the trial therapy studied was optimal, whether the sample size was adequate, and the impact of adjunctive treatments. In thrombolytic trials in particular, regional variations in attitudes to coronary angiography may have affected outcomes. Clinical trial results need to be interpreted in the light of the cost effectiveness of the application. The assessment of clinical outcomes depends on interplay between the structure and process of care, patient factors and chance. Large standardised databases are necessary to assess clinical practice and outcomes.
BACKGROUND: Clinical practice guidelines (CPGs) can be helpful in distilling the medical research literature for clinicians; however, the guidelines should acknowledge the variable methodological quality used in clinical research by tempering their recommendations with a 'levels of evidence' scale. OBJECTIVE: To evaluate the proportion of English-language cardiovascular CPGs that provide the user with recommendations graded according to a defined levels of evidence scale. In addition, to evaluate other key aspects important in the critical appraisal of CPGs. METHODS: CPGs for atrial fibrillation, congestive heart failure and myocardial infarction were identified by searching MEDLINE, a reference text of CPGs and the Internet. Each CPG was evaluated using a priori-defined criteria based on the Evidence-Based Medicine Working Group's paper on critical appraisal of CPGs, including use of a reproducible search strategy, method of obtaining consensus, peer review and testing in practice. RESULTS: A total of 95 CPGs were evaluated. Only 13% graded their recommendations using a defined levels of evidence scale. In addition, few CPGs documented a reproducible search strategy or peer review process, and none had been formally tested in practice. CONCLUSIONS: Reporting the levels of evidence for recommendations is an important component of CPGs, yet this system is not widely used.
A clinical practice guideline for the screening and diagnosis of gestational diabetes mellitus (GDM) is currently implemented at Siriraj Hospital. During the year 2000, a total of 9325 pregnant women were screened for clinical risk factors during their first antenatal visits, and 3770 had at least 1 risk. After the 50 g glucose challenge test and 100 g oral glucose tolerance test, GDM was diagnosed in 235 women. The incidence of GDM was 6.2 per cent (95% CI 5.5-7.1) among high-risk pregnant women, and 2.5 per cent (95% CI 2.2-2.9) of all pregnant women. Significant risk factors identified from the present study were family history of DM (adjusted OR 1.86, 95% CI 1.38-2.51), age > or = 30 years (adjusted OR 2.41, 95% CI 1.72-3.39), history of unexplained intrauterine fetal death (adjusted OR 4.30, 95% CI 2.04-9.04), and obesity (adjusted OR 2.83, 95% CI 1.88-4.25). The risk of developing GDM also increased when more than 1 clinical risk factor was identified. The results support the value of this screening program for GDM. Every obstetrician should be aware of the need to screen for GDM in every pregnant woman and a similar program should also be introduced to other settings.

Clinical practice improvement (CPI) is a method for examining the steps of a care process to determine how to achieve the best medical outcomes at the least necessary cost over the continuum of a patient's care. This methodology includes tracking of medical care process factors (management strategies, interventions, medications), patient factors (physiologic severity of illness and psychosocial deviations at each visit), and outcomes and furnishes information that presents distinct advantages over information furnished by outcomes research or clinical trials in the designing of management protocols. The Managed Care Outcomes Project, a large-scale CPI study, examined the effects of health maintenance organization (HMO) cost-containment strategies on patient outcome and utilization of care. Approximately 13,000 patients with otitis media, arthritis, hypertension, asthma, or ulcer disease were analyzed; since all patient diagnoses and medication use were captured in the CPI model, my colleagues and I were able to assess factors in psychiatric illness diagnosis, treatment, and outcome. Among the findings were the following: (1) the majority of patients receiving psychiatric drugs do not have a specific psychiatric diagnosis; (2) a significant proportion of patients with a specific diagnosis of major depression do not receive antidepressant medication; (3) cost-containment strategies appeared to markedly limit psychiatric referral and frequency of visits and use of serotonin selective reuptake inhibitor treatment; and (4) severity of the primary illness in the study population was markedly increased in patients with a psychiatric diagnosis. Further analysis of data from this study may help to determine which processes of care for depression were associated with better outcomes.
Clinical practice is supposed to be evidence-based but it always conveys underlying values, judgements, moral principles or axioms. We explore the evidence-based nature of clinical practice in the fast-changing field of kidney transplantation and its relationship with values in five different interventions: those well supported on evidence, focussed on the use of immunosuppressant drugs like cyclosporine, mycophenolate mofetil and tacrolimus, and the elective withdrawal of cyclosporine or steroids; disputable interventions where evidence, focussed on anti-lymphocyte antibodies, is strong but not strong enough to be applied on the majority of occasions; interventions not supported by randomised controlled trials with focus on primary treatment of vascular graft rejection and rescue treatment for acute graft rejection; interventions not widely applied despite strong evidence from sources other than randomised controlled trials, with focus on HLA-matched kidney transplants in cadaver donor and living donor transplants; and finally, a variety of interventions when evidence is lacking. Being aware of the factors influencing every clinical decision we can make the strength of evidence and the nature of the values underlying them explicit and we will find it easier to improve the process of transferring evidence into practice and openly face and acknowledge the values involved.
In current clinical practice, oral anticoagulant therapy is one of the most widely employed treatments in order to prevent embolic events in cardiovascular diseases. This therapy is bound to become more and more employed because of increasing mean age of general population and related increase of clinical settings which may require anticoagulation. Nowadays, available drugs for oral anticoagulation are vitamin K antagonists which inhibit the coagulation factors depending upon this vitamin for their synthesis. In this review we will examine: --their mechanism of action and its clinical implications related with the initial phase of therapy and the likelihood of side effects as cutaneous necrosis; --their pharmacokinetics which explain most of drug interactions; --affecting therapy factors: age of patients, impaired absorption, genetic polymorphisms of cytochrome P450, drug resistance, coagulation factors defects, particular clinical situations, vitamin K dietary intake; --different properties of various anticoagulant drugs; --toxicity; --problems related to monitoring anticoagulation intensity. At last, we will present the new pharmacological perspectives offered by direct inhibitors of the coagulation factors.
These clinical practice guidelines aim at providing assistance mainly to primary health care physicians for the diagnosis and management of acute sinusitis. Despite the huge impact of upper respiratory infections, criteria for diagnoses are often vague, and physicians are often uncertain of their diagnoses. This is not surprising, as the sole definition of acute sinusitis is somewhat confusing, not to mention the existing discrepancies between treatments, even among specialists. The Finnish Society of Otorhinolaryngology has set up a committee to evaluate existing data on acute sinusitis and to formulate these guidelines. The committee comprised Finnish experts in adult and paediatric otorhinolaryngology, clinical microbiology, radiology, paediatrics, and epidemiology. Recommendations given are based on the principles of evidence-based medicine, with the level of evidence presented.
Clinical guidelines are a very hot topic. Many guidelines are being published, but many concerns about guidelines still exist. Guidelines may be able to increase the quality of health care while eliminating unnecessary or inappropriate care. Critics wonder if the process will instead lead to poorer care and a waste of time and effort. Although guidelines are targeted on providers of care, those with other roles will use guidelines for optimizing patient care and outcomes, assuring quality, cutting costs and tracking liability and risk management. Examination of guidelines and their impact suggest that the process and product are imperfect and that the impact is difficult to measure. The chiropractic profession will continue in its guideline efforts. The direct effects of guidelines will be on certain aspects of doctor knowledge, attitude, belief and behavior. The indirect effects will be largely attitudinal in nature at first but will eventually lead to action. The profession will embrace the need to (a) develop a more comprehensive and useful research database and (b) to develop sophisticated means for obtaining profession-wide consensus on fundamental clinical issues.
