Doctors must keep up to date with developments in their field and maintain their skills medicine 4h2 discount 50mg lamictal mastercard. If doctors have teaching responsibilities treatment ingrown toenail purchase lamictal with american express, they must develop the skills treatment xanax overdose order lamictal no prescription, attitudes, and practices of a competent teacher. All curricula must include curricular outcomes that are consistent with those set out below. Maintaining good medical practice (a) Be able to gain, assess, apply, and integrate new knowledge and have the ability to adapt to changing circumstances throughout their professional life. Working with colleagues (a) Know about, understand and respect the roles and expertise of other health and social care professionals. Probity Graduates must demonstrate honesty in all areas of their professional work. Health Graduates must be aware of the importance of their own health, and its effect on their ability to practise as a doctor. Appendix 2 The aims of the Preregistration House Officer (PRHO) year ("general clinical training") • When universities grant a registrable degree, they are certifying that their graduates have attained the goals of undergraduate medical education, as set out in the GMC’s Recommendations on Undergraduate Medical Education, Tomorrow’s Doctors, and that they have demonstrated competence in their published list of procedures. Many of its aims are similar to those for undergraduate education and for the later stages of professional training, since medical education is a continuum. General clinical training builds on the attitudes, skills and knowledge graduates have developed and should enable them, as new doctors, to: (a) appreciate the centrality to the consultation by developing their competence in history taking, clinical examination, and the selection and interpretation of diagnostic tests (b) develop competence at diagnosis, decision making, and the provision of treatment, including prescribing (c) keep accurate records (d) refine the skills needed for the technical and practical procedures which any doctor should be able to perform (e) communicate effectively, both orally and in writing, with those with whom their professional practice brings them in contact: patients, relatives, healthcare professionals, and people in the community (f) develop and maintain respect for the dignity, privacy, and rights of patients, and concern for their relatives (g) work in a team and accept the principles of collective responsibility 138 APPENDICES (h) be aware of their own limitations and ready to seek help when necessary (i) develop their knowledge and understanding of disease processes, including their natural history, the role of occupation in disease, and the possibilities for rehabilitation (j) deepen their awareness of legal and ethical issues (k) apply the principles of professional confidentiality in everyday practice (l) understand the principles of evidence-based medicine (m) understand the relationship between primary and social care and hospital care (n) recognise and use opportunities for disease prevention and health promotion (o) understand and use informatics as a tool in medical practice (p) understand the purpose and practice of audit, peer review, and appraisal (q) recognise self-education and professional development as a lifelong process (r) develop appropriate attitudes towards personal health and well-being (s) manage time effectively (t) make the best use of laboratory and other diagnostic services (u) follow safe practices (as detailed in their employer’s occupational health and safety policy), relating to chemical, biological, physical, and psychological hazards in the workplace. From The New Doctor—Recommendations on General Clinical Training, General Medical Council, 1997. Appendix 3Guidance to doctors Being registered with the General Medical Council gives you rights and privileges. In return you must meet the standards of competence, care and conduct set by the GMC. The duties of a doctor registered with the General Medical Council Patients must be able to trust doctors with their lives and wellbeing. To justify that trust, we as a profession have a duty to maintain a good standard of practice and care and to show respect for human life. In particular as a doctor you must: • Make the care of your patient your first concern • Treat every patient politely and considerately 139 APPENDICES • Respect patients’ dignity and privacy • Listen to patients and respect their views • Give patients information in a way they can understand • Respect the rights of patients to be fully involved in decisions about their care • Keep your professional knowledge and skills up to date • Recognise the limits of your professional competence • Be honest and trustworthy • Respect and protect confidential information • Make sure that your personal beliefs do not prejudice your patients’ care • Act quickly to protect patients from risk if you have good reason to believe that you or a colleague may not be fit to practice • Avoid abusing your position as a doctor • Work with colleagues in the ways that best serve patients’ interests. In all these matters you must never discriminate unfairly against your patients or colleagues. Appendix 4 Suggestions for further reading Getting into Medical School by Jim Burnett.

The lack of knowledge of marketing symptoms 0f pneumonia purchase lamictal with a visa, and its potential impact treatment zinc deficiency buy generic lamictal 50mg line, has led health professionals to consider marketing at best a necessary evil medical treatment order lamictal visa. Furthermore, there is widespread concern that marketing can do little to alter practice patterns, market shares, or any other indica- tor of importance to the provider. Ethical and Legal Constraints A major barrier to the incorporation of marketing into healthcare has been the ethical and legal constraints that have characterized the industry. Until recently it was considered unethical for physicians and many other clini- cians to advertise. While other types of marketing were generally accepted, overt advertising initiatives were discouraged, if not prohibited. Physicians were restrained by professional considerations, and hospitals often imposed internal constraints on their marketing activities. In some cases legal restraints have prohibited advertising and other overt forms of marketing. The Federal Trade Commission, for example, has placed limits on the types and content of advertising that pharmaceu- tical companies and other healthcare consumer products companies can provide. Congressional legislation has been enacted to limit the marketing activities of providers being reimbursed under the Medicare and Medicaid programs. The nature of health-related goods and services had made them the target of restrictions not found in other industries. As many marketers who enter healthcare from other industries have found, mar- keting philosophies and techniques cannot readily be transferred from other industries to healthcare. For this reason healthcare marketing requires its own unique approach and takes on characteristics unlike those in any other sector of the economy. One factor that makes healthcare marketing different is the nature of the demand for health services. While the demand for health services has a certain elasticity overall, and elective procedures for which demand can actually be generated exist, most major healthcare episodes occur relatively rarely and almost always unpredictably. Such major events as a heart attack, a stroke, or the onset of cancer are likely to arise unexpectedly Box 2. Concerns over the mar- keting practices of various medical remedies can be traced back 200 years—to the days of patent medicines sold on street corners, at carnivals, and through traveling salesmen. Eventually, government regulations were put into place to control the claims of purveyors of such products and, with the support of the American Medical Association (AMA), the first medicine labeling laws were passed in 1938. Today the fed- eral Food and Drug Administration and Federal Trade Commission serve as watchdogs over health-related products. In the post–World War II period, physicians commonly endorsed various products in exchange for payment from the product’s producer. Physicians were paid to endorse various pharmaceutical products, for example, indicating that one drug was superior to its competitors. During this period, physicians sometimes strayed from their areas of expert- ise and endorsed other products as well. The most controversial of these actions involved the endorsement of various cigarette brands. Doctors were paid to attest that Brand X was healthier for the consumer to smoke than Brand Y. The influence of the AMA and other forces were eventually brought to bear, and such practices were eliminated. These experiences led to a virtual prohibition, enforced by the AMA, of marketing on the part of physicians.
