The more criteria in the schema that are fulfilled prevacid 15 mg line gastritis diet king, the more potentially useful the test will be cheap prevacid 15mg with visa gastritis diet 101. This is usually a function of the instrumentation or operator reliability of the test. While precision used to be assumed to be present for all diagnostic tests, many studies have demonstrated that with most non-automated tests, there is some degree of subjectivity in test inter- pretation. It is also present in tests commonly considered to be the “gold standard” such as the interpretation of tissue samples from autopsies, biopsies, or surgery. The determina- tion of accuracy depends upon the ability of the instrument’s result to be the same as the result determined using a standardized specimen and 1 W. A person with more experience, better train- ing, or more talent will get more precise and accurate results on many tests. If a test is very expensive and not covered by health insurance, the patient may not be able to pay for it, making it a useless test for them. The substances may also prevent the test from picking up true positives and thereby make them false negatives. An example of this if a person eats poppy- seed bagels, they will give a false positive urine test for opiates. Criterion-basedvalidity describes how well the measurement agrees with other approaches for measuring the same characteristic, and is a very important measurement in studies of diagnostic tests. The result of a gold-standard test defines the presence or absence of the dis- ease (i. There are very few true gold standards in medicine and some are better or scientifically more pure than others. These are traditionally consid- ered to be the ultimate gold standard, but their interpretations can vary with different pathologists. Theoretically, all bacteria that are present in the blood should grow on a suitable culture medium. Sometimes, for technical reasons, the culture does not grow bacteria even though they were present in the blood. This can occur because the technician doesn’t plate the culture properly, it is stored at an incorrect temperature, or there just happened to be no bacteria in the particular 10-cc vial of blood that was sampled. This is a set of fairly objective cri- teria for making a diagnosis of rheumatic fever. Factors that could decrease the accuracy of these criteria are that a component of the criteria, such as temperature, may be measured incorrectly in some patients, or another criterion like arthritis may be interpreted incor- rectly by the observer. These criteria are objective, yet depend on the clinician’s interpretation of the patient’s descrip- tion of their symptoms. As mentioned previously, x-rays are open to variation in the reading, even by experienced radiologists. If we are ultimately interested in finding out how well a test works to separate the diseased patients from the healthy patients, we can follow everyone who received the test for a specified period of time and see which outcomes they all have. This technique works as long as the time period is long enough to see all the possible dis- ease outcomes, yet short enough to study realistically. Does the result of the test cause a change in diagno- sis after testing is complete? If we are almost certain that a patient has a dis- ease based upon one test result or the history and physical exam, we don’t need a second test to confirm that result. Diagnostic thinking only considers how the test performs in making the diagnosis in a given clinical setting, and is therefore closely related to diagnostic accuracy. The setting within which this thinking operates is dependent on the prevalence of the disease in the patient population being tested. For example, the venogram is the gold-standard test in the diagnosis of deep venous thrombosis. It is an expensive and invasive test that can cause some side effects, although these side effects are rarely lethal. Part of the art of medicine is determining which patients with one negative ultrasound can safely wait for a confirmatory ultrasound 3 days later, and which patients 248 Essential Evidence-Based Medicine need to have an immediate venogram or initiation of anticoagulant medica- tion therapy. This considers biophysiological parameters, symptom severity, functional outcome, patient utility, expected values, morbidity avoided, mor- tality change, and cost-effectiveness of outcomes. We will discuss some of these issues in the chapter on decision trees and patient values (Chapter 31). Even a cheap test, if done excessively, may result in prohibitive costs to society.

All data and analyses were evaluated and interpreted in Tuning taskforce workshops buy cheap prevacid 30mg gastritis sintomas. The fnal outcomes framework generic prevacid 15mg visa gastritis sintomas, as part of a “Tuning Brochure” for medicine, was presented at a Sectoral Validation Conference, Brussels, June 007. An Expert Panel, external to the Tuning Task Force reviewed the outcomes framework and met with members of the Task Force. The Expert Panel endorsed the approach of the project and content of the outcomes framework. The fnal report and outcomes framework were presented to the European Commission in January 008. This process of discussion and agreement was at the heart of the Tuning (medicine) project. For example, “Ability to provide evidence to a court of law“ was rated very low by respondents as a core outcome and so was removed as a Level outcome. The original draft included the following Level outcomes: • Ability to design research experiments • Ability to carry out practical laboratory research procedures • Ability to analyse and disseminate experimental results These were rated very low by respondents in terms of importance for all graduates as core outcomes of the primary medical degree. The conclusion was that under the Level 1 outcome ‘Ability to apply scientifc principles, method and knowledge to medical practice and research’, no specifc Level outcomes should be included. Similarly, “Research skills”, with no further specifcation, is included as an outcome under Medical professionalism. This leaves it open to individual countries, schools or students to decide how to prioritise practical research experience, in keeping with their profle, educational philosophy or career intentions. Individual schools can also select additional learning outcomes in order to develop or preserve a distinct educational profle – for example, a specifc emphasis on research-related experience and skills - without compromising the essential competence of their graduates and their ftness to care for patients. The structure of the outcomes framework has been chosen to be useful to those involved in planning and designing new undergraduate medical degree programmes. The Level 1 outcomes describe domains of teaching, learning and assessment that lend themselves to becoming “curriculum themes”, with defned academic leadership and dedicated resources. The Level outcomes can help to defne the content of such themes in terms of teaching, learning and assessment. The Professionalism outcomes are relevant when addressing the personal and professional development and ftness to practise of medical students. In future work we aim to document best practice in learning, teaching and assessing these outcomes. Meantime useful information on outcome-based assessment can be accessed through the Scottish Doctor website (http://www. Mobility It seems likely that schools which share a common set of graduating learning outcomes will fnd it much more straightforward to exchange students and staf, particularly in the later parts of the curriculum. Similarly, assurance that graduates have achieved the necessary learning outcomes is likely to facilitate mobility of doctors in Europe and provide reassurance to employers and patients. Quality enhancement and quality assurance Consideration of a medical school’s graduating outcomes in relation to an agreed framework should be an integral part of quality assurance and accreditation, sitting alongside evaluation of education process and infrastructure. Recently developed methodologies permit systematic mapping of one outcomes framework against another, so that a school’s learning outcomes could simply be cross-referenced against the European framework (Ellaway, R et al, 007). Although it is likely that national systems of quality assurance and accreditation will continue to predominate in Europe, the Tuning outcomes can support a developing European dimension in medical education as part of a harmonisation process.

Medical Teacher, 007; 9:636-641 3 Appendix A: Knowledge Outcomes Although not formally part of Tuning methodology, the web-base questionnaire survey also sought opinion about important areas of knowledge for medical graduates. In general, the highest scores and rankings related to knowledge of traditional scientifc disciplines which underpin medical practice, such as physiology, anatomy, biochemistry, and immunology, together with clinical sciences such as pathology, microbiology and clinical pharmacology. The lowest ranking related to knowledge of “diferent types of complementary / alternative medicine and their use in patient care”. Graduates from medical degree programmes in Europe should be able to demonstrate knowledge of: Basic Sciences Normal function (physiology) Normal structure (anatomy) Normal body metabolism and hormonal function (biochemistry) Normal immune function (immunology) Normal cell biology Normal molecular biology Normal human development (embryology) Behavioural and social sciences Psychology Human development (child/adolescent/adult) Sociology Clinical Sciences Abnormal structure and mechanisms of disease (pathology) Infection (microbiology) Immunity and immunological disease Genetics and inherited disease 4 Drugs and prescribing Use of antibiotics and antibiotic resistance Principles of prescribing Drug side efects Drug interactions Use of blood transfusion and blood products Drug action and pharmacokinetics Individual drugs Diferent types of complementary / alternative medicine and their use in patient care Public Health Disease prevention Lifestyle, diet and nutrition Health promotion Screening for disease and disease surveillance Disability Gender issues relevant to health care Epidemiology Cultural and ethnic infuences on health care Resource allocation and health economics Global health and inequality Ethical and legal principles in medical practice Rights of patients Rights of disabled people Responsibilities in relation to colleagues Role of the doctor in health care systems Laws relevant to medicine Systems of professional regulation Principles of clinical audit Systems for health care delivery 5 Appendix B: Clinical Attachments and Experiential Learning Although not formally part of Tuning methodology, the web-base questionnaire survey also sought opinion about which areas of clinical medical practice were most important to be included as part of the core undergraduate medical school programme. In general, the highest rankings related to acute medical and surgical care settings, with community and primary care also ranking highly.
