Paul C 《Physician executive》1995,21(10):42-43
Recently, the number of physicians who have been interested in alternative careers has vastly increased. Many physicians express dissatisfaction with clinical practice, but they are uncertain about which nonclinical options are appropriate for them. Pursuing a different career after many years of studying and practicing medicine can seem like an overwhelming task. In this article, the author briefly outlines a decision-making process that can be used in analyzing career options and suggests some careers that have provided challenging opportunities for physicians. 相似文献

The dramatic increase in U.S. cesarean sections over the past two decades has been significantly driven by repeat C-sections. In response to this trend, clinical guidelines recommending vaginal birth after cesarean-section (VBAC) have been promulgated by national organizations. Adherence to these guidelines would reduce the number of repeat C-sections, lower the overall C-section rate, and improve both the quality and the cost of health care. While these guidelines have received professional endorsement, their implementation has been clouded by issues of patient acceptance and provider payment. To examine implementation of these guidelines by health care organizations, the authors surveyed 156 members of the American College of Physician Executives to determine their policies, practices, and attitudes toward VBAC guidelines. Those surveyed generally were medical directors in HMOs, hospitals, and other practice settings. The findings indicate that the health care organizations represented by these physician executives have not consistently implemented VBAC guideline and that they are reluctant to hold physicians, their patients, or hospitals accountable for the financial, utilization, and quality impact of the elective decision ot to pursue appropriate VBACs. We conclude that, even when widely accepted, clinical practice guidelines may be ineffective in reducing the costs or improving the quality of medical care. 相似文献

Thompson RE 《Physician executive》1995,21(11):9-11
When the author gazed into the proverbial mirror and asked if the U.S. health care system was the fairest of them all, it shattered. In this article, Thompson tells why the system is broken and what failure to fix it means to physician executives. He suggests that we, as Americans, must reinvent ourselves by realigning our value systems and and stifling our obsession with profit before trying to reinvent health care. 相似文献

This study investigated the relative effectiveness of specific genital regional self-stimulation in elevating pain thresholds. Anecdotal reports in humans suggest that sexual activity and orgasm decrease a wide variety of human responses to pain and touch, but the phenomenon has not been evaluated objectively. Two types of self-stimulation, pressure and pleasurable, were applied by 10 women to the anterior vaginal wall, the posterior vaginal wall, and the clitoris. Significant increases in pain thresholds but not tactile thresholds occurred when pressure stimulation was applied to the anterior wall of the vagina or when "pleasurable" self-stimulation was applied to any of the three areas. Tactile thresholds were not significantly affected by any genital stimulation condition. However, there was a significant increase in tactile threshold but not pain thresholds in the distraction control condition. On the basis of these findings, we conclude that (a) a sensation of pleasure evoked by genital stimulation can elevate pain thresholds, (b) these pleasurable stimuli were not general "distractants" because they elevated pain thresholds but not tactile thresholds differentially, and (c) genital pleasurable stimuli activate an analgesic process that is distinct from a distraction process. 相似文献

Patients' views of patient-physician interactions—particularly the perspectives of older, ethnically diverse women—are poorly understood. The older patient's attitude toward and understanding of the medical encounter, however, are essential to the design of strategies to improve patient-physician communication. To date, investigations have primarily emphasised the ways in which the therapeutic relationship is influenced by immutable patient characteristics. This qualitative study extends previous research findings by looking beyond the effect of ascribed categories (such as age, race, and gender) and focusing on aspects of patient behavior, specifically assertiveness. Focus groups were conducted with older African-, Chinese-, European-, and Hispanic American breast cancer patients from sites in the eastern and western United States. The study explores the potential of a form of patient activation for challenging stereotypes of the elderly and changing health care practitioners' behavior. 相似文献

Participant-observation can teach us much about the everyday meanings of doing social activism. I conceptualize these implicit meanings in relation to work in the sociology of culture, and social movement studies, and give examples from activists' everyday interaction. A participant-observer's forays into implicit meanings illuminate three dimensions of activists' experiences: the ways activists practice democratic citizenship in their groups, the ways they build group ties, and the ways they define the meaning of activism itself. By probing these implicit meanings, we can address questions that concern many social movement scholars. We increase our understanding of how movements grow, accomodate conflict, and build alliances, and we can specify which insights are useful in theories of contemporary or new social movements. 相似文献

This chapter is about a very old question that is thrown up again in discussion related to ANT. Do orders have necessary limits to what can belong to them? It is possible to read ANT as containing or demanding a moral commitment to the inclusion of the disenfranchised. It can often seem to be in the business of giving credit where credit is due, spreading recognition to even the most unexpected quarters. To sustain itself such a morality would depend on the possibility of infinite inclusion. By identifying this picture of 'belonging-by-assemblage' and its traditional counterpart 'belonging-by-banishment' and by finding both at play within ANT, the papers argues that ANT is an ethical rather than a moral enterprise, bringing the unanswered question of the nature of belonging to bear across domains, rather than approaching each domain with a 'cookie-cutter' moral formula. The disturbing 'unsecuring' of belonging that ANT involves continues within the philosophical tradition ANT trades on and contributes to in the form of an abiding controversy over the place of the natural world. 相似文献
