Health service researchers believe that significant practice variations occur, in part, because there is no strong consensus on best practices for managing a specific condition. The Agency for Health Care Policy and Research supports the development of science-based clinical guidelines, performance measures, and standards of quality. Since 1992, it has published 6 clinical guidelines and is supporting development of more than 20 others. Each has a consumer version, in English and Spanish, to educate patients and describe care options. Widespread use of these guidelines will improve the quality of health care by assisting providers in making more informed decisions, thereby reducing unnecessary health care practices; will reduce some costs; and will provide feedback on knowledge gaps that merit the attention and support of researchers and policymakers.

Indicates that social and policy-making circumstances have altered social scientists' freedom of inquiry and right to pursue research without political interference. While critical control should be exercised by the research community, repressive political control presents a dangerous roadblock to scientific exploration.

With the emergence of humanistically oriented therapies, and given recent developments, a different view of the therapist–client relationship has evolved. Although touch has long been associated with healing in most cultures, Freud and other psychoanalysts established a no-touch rule in the therapist–client relationship. Critics of the touch taboo argue that the blank screen stance of therapists recreates the cold and distance environment that contributed to the client's dysfunction, and it ignores the value of touch as a powerful therapeutic ingredient, one which emphasized a more open and intimate relationship between client and therapist. Today there is a lack of consensus about the use of touch and the complex ethical and clinical issues surrounding its use. This article review the clinical and research literature and explores views for and against using touch in therapy. Given the powerful effect of touch and the legal climate in our society, ethical and clinical guidelines are presented to assist the therapist in using touch appropriately, with sensitivity and skill.

In the past several years, considerable attention has been focused on clinical practice guidelines. They are developed to foster improved clinical care and to increase clinical efficiency. The legal implications of developing and following guidelines are not yet clear. The author argues that properly formulated guidelines could reduce the burdens of preventing and resolving malpractice claims. 相似文献

OBJECTIVE: To determine which attributes of clinical practice guidelines influence the use of guidelines in decision making in clinical practice. DESIGN: Observational study relating the use of 47 different recommendations from 10 national clinical guidelines to 12 different attributes of clinical guidelines-for example, evidence based, controversial, concrete. SETTING: General practice in the Netherlands. SUBJECTS: 61 general practitioners who made 12 880 decisions in their contacts with patients. MAIN OUTCOME MEASURES: Compliance of decisions with clinical guidelines according to the attribute of the guideline. RESULTS: Recommendations were followed in, on average, 61% (7915/12 880) of the decisions. Controversial recommendations were followed in 35% (886/2497) of decisions and non-controversial recommendations in 68% (7029/10 383) of decisions. Vague and non-specific recommendations were followed in 36% (826/2280) of decisions and clear recommendations in 67% (7089/10 600) of decisions. Recommendations that demanded a change in existing practice routines were followed in 44% (1278/2912) of decisions and those that did not in 67% (6637/9968) of decisions. Evidence based recommendations were used more than recommendations for practice that were not based on research evidence (71% (2745/3841) v 57% (5170/9039)). CONCLUSIONS: People and organisations setting evidence based clinical practice guidelines should take into account some of the other important attributes of effective recommendations for clinical practice. 相似文献

A clinical trial is a research study conducted in humans and designed to answer specific questions using scientifically controlled methods. These trials require considerable effort to assure that the data obtained are reliable, reproducible, and readily available. Data managers play a key role in this research effort. A nurse with a clinical background, computer knowledge, and some experience in the research environment is well suited for the role of data manager. The data manager performs a variety of tasks in this position that will enhance the quality of the data gathered in a research study. These responsibilities include designing forms, monitoring protocol accrual, abstracting data, entering data onto protocol-specific forms and/or specifically designed computerized data-entry screens, assuring the quality and the integrity of the data, and providing investigators with interim and summary reports. In addition, the data manager can be responsible for the management of a computerized clinical data base system, including the training of users and the designing of basic reports for the investigators. A nurse, functioning as a data manager, who understands research methodology, is detail oriented, and is well organized, could be a valuable asset to the clinical trials team in the successful management of any clinical study. 相似文献

In cardiac fibroblasts, angiotensin II (Ang II) induced a rapid increase in extracellular signal regulated kinase (ERK) activity in a pertussis toxin insensitive manner. This ERK activation was abolished by the Gq-associated phospholipase C inhibitor U73122 but was insensitive to protein kinase C (PKC) inhibitors or PKC downregulation by phorbol ester. Intracellular Ca2+ chelation by BAPTA-AM or TMB-8 abolished Ang II induced ERK activation, whereas treatment with EGTA or nifedipine did not affect it. Ca2+ ionophore A23187 also induced a rapid increase in ERK activity to an extent similar to that of Ang II stimulation. Calmodulin inhibitors (W7 and calmidazolium) and tyrosine kinase inhibitors (genistein and ST638) completely blocked ERK activation by Ang II and A23187. Both Ang II and A23187 caused a rapid increase in the binding of GTP to p21(Ras), which was nearly abolished by genistein and calmidazolium. Transfection with the dominant negative mutant of Ras and the Ras inhibitor manumycin completely inhibited Ang II induced ERK activation. It was also found for the first time that cardiac fibroblasts abundantly expressed Ca2+-sensitive tyrosine kinase Pyk2/CAKbeta/RAFTK and that Ang II markedly induced its activation in a Ca2+/calmodulin-sensitive manner. Overexpression of the dominant negative mutant of Pyk2 significantly attenuated Ang II or A23187-induced ERK activities (36% and 38% inhibition compared with that in mock-transfected cells, respectively) and ERK tyrosine phosphorylation levels, as well as an increase in the binding of GTP to p21(Ras). These findings demonstrate that in cardiac fibroblasts, Ang II induced Ras/ERK activation is dominantly regulated by Gq-coupled Ca2+/calmodulin signaling and that Pyk2 plays an important role in the signal transmission for efficient activation of the Ang II induced Ras/ERK pathway. 相似文献

This paper argues that the major barrier to implementing program evaluation systems is not the lack of an adequate evaluation technology but rather the lack of an adequate foundation of trust. Basic psychological research in the areas of experimental games, source credibility, and interpersonal trust was examined in order to provide psychologists and other professionals with some potential guidelines for trust development. Application of the guidelines was illustrated with examples from two departments in a particular university setting. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

PURPOSE: To present an update on the development of oncology practice guidelines (PGs) using the Practice Guidelines Development Cycle (Cycle), and to present the results of surveys of oncologists on the first 10 guidelines from the Cancer Care Ontario Practice Guidelines Initiative. METHODS: Practitioners' opinions about guidelines in development were sought using a mail survey method with systematic follow-up. Practitioners were identified by cancer center representatives. Survey packages included evidence-based recommendations (EBRs) and a one-page, nine-item feedback questionnaire. Data were collected between February 1995 and February 1996. RESULTS: Nine hundred fourteen surveys that pertained to 10 guidelines were mailed to 423 practitioners in Ontario. Practitioners included 112 medical oncologists/hematologists, 34 radiation oncologists, 195 surgeons, and 82 practitioners from other medical specialities. One hundred practitioners were located in cancer centers and 323 had community-based practices. The overall response rate by practitioner was 72% and by survey questionnaire, 70%. For the five questionnaire items that assessed guideline quality, approval ratings ranged from 86% to 92%. For the 10 recommendations, 77% ( 63% to 82%) of respondents agreed that the EBR could be approved as a PG. Response and approval rates were consistent across medical specialities and locations of practice. CONCLUSION: The process of obtaining practitioner feedback in the development of PGs is both feasible and useful. The high response rates to the survey indicate that it is possible to obtain broad participation in evidence-based guidelines development throughout Ontario. The changes made to the EBRs in response to feedback suggest that practitioners' opinions can be valuable in shaping evidence-based guidelines. 相似文献

BACKGROUND: The aim of this prospective study was to test a new protocol for iron supplementation in haemodialysis patients, as well as to assess the utility of different iron metabolism markers in common use and their 'target' values for the correction of iron deficiency. METHODS: Thirty-three of 56 chronic haemodialysis patients were selected for long-term (6 months) i.v. iron therapy at 20 mg three times per week post-dialysis based on the presence of at least one of the following iron metabolism markers: percentage of transferrin saturation (%TSAT) <20%; percentage of hypochromic erythrocytes (%HypoE) > 10% and serum ferritin (SF) <400 microg/l. Reasons for patient exclusion were active inflammatory or infectious diseases, haematological diseases, psychosis, probable iron overload (SF > or =400 microg/l) and/or acute need of blood transfusion mostly due to haemorrhage and change in renal replacement treatment. RESULTS: More than half (51.8%) of the patients of our dialysis centre proved to have some degree of iron deficiency in spite of their regular oral iron supplementation. At the start of the study the mean haemoglobin was 10.8 g/dl and increased after the 6 months of iron treatment to 12.8 g/dl (P<0.0001). The use of erythropoietin decreased from 118 units/kg/week to 84 units/kg/week. The criterion for iron supplementation with the best sensitivity/specificity relationship (100/87.9%) was ferritin <400 microg/l. Patients with ferritin < 100 [microg/l and those with ferritin between 100 microg/l and 400 microg/l had the same increase in haemoglobin but other parameters of iron metabolism were different between the two groups. CONCLUSIONS: Routine supplementation of iron in haemodialysis patients should be performed intravenously. Target ferritin values should be considered individually and the best mean haemoglobin values were achieved at 6 months with a mean ferritin of 456 microg/l (variation from to 919 microg/l). The percentage of transferrin saturation, percentage of hypochromic erythrocytes and ferritin <100 microg/l, were not considered useful parameters to monitor routine iron supplementation in haemodialysis patients. No significant adverse reactions to iron therapy were observed. 相似文献

The implementation of a quality assessment program on a large scale requires the construction of explicit, objective criteria for review. Optimally, the source of criteria should be established research findings. Given the current state of the art, experimental data will only provide a limited amount of information. The present paper examines empirical activities that can support criteria construction. (2 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

Two subjects are discussed: the use of placebo controls in clinical trials and informed consent. Particularly in trials of drugs for disorders for which there exist effective treatments, the use of placebo is still controversial, although anyhow in violation of the Declaration of Helsinki. Informed consent aims at giving a subject all the necessary information to allow him to decide, with full knowledge, whether to accept a particular treatment or experimental protocol. Its importance would seem, albeit essential, to be rather illusory. 相似文献

OBJECTIVE: To determine possible indications for tracheotomy in the burned child based on bronchoscopic and laryngoscopic findings. DESIGN AND SETTING: A retrospective case study of all patients admitted to a tertiary children's burn center. PARTICIPANTS: All children admitted with burn inhalation injury between 1990 and 1995 (n = 211). INTERVENTION: All patients underwent laryngoscopy and bronchoscopy and 19 underwent tracheotomy, with 5 tracheotomy tubes placed emergently. MAIN OUTCOME MEASURES: Observations during laryngoscopy and bronchoscopy included erythema, edema, carbonaceous material, ulcerations, and bronchial mucous casts. The supraglottis, glottis, and subglottis were analyzed separately, when possible. Any sepsis resulting from tracheotomy was determined. Complications, such as glottic webs, subglottic stenosis, and tracheomalacia, were noted. RESULTS: Indications for tracheotomy included 6 for airway obstruction, 6 for prolonged intubation, 6 for pulmonary cleansing, and 1 for endotracheal tube complications (subglottic stenosis). When examined by bronchoscopy and laryngoscopy, 17 of 19 children had significant airway edema, 10 had carbonaceous material in the airway, and 3 had ulcerations in the airway. CONCLUSIONS: Tracheotomy is indicated in the burned child when significant airway edema is present. Failure to place a tracheotomy tube in these cases leads to a high incidence of immediate tracheotomies (26%). There was no evidence of clinically significant infection attributable to tracheotomy. The number of airway complications due to tracheotomy was no higher than from endotracheal intubation. 相似文献
