OBJECTIVE: To describe gender differences in job satisfaction, work life issues, and burnout of U.S. physicians. DESIGN/PARTICIPANTS: The Physician Work life Study, a nationally representative random stratified sample of 5,704 physicians in primary and specialty nonsurgical care ( N = 2,326 respondents; 32% female, adjusted response rate = 52%). Survey contained 150 items assessing career satisfaction and multiple aspects of work life. MEASUREMENTS AND MAIN RESULTS: Odds of being satisfied with facets of work life and odds of reporting burnout were modeled with survey-weighted logistic regression controlling for demographic variables and practice characteristics. Multiple linear regression was performed to model dependent variables of global, career, and specialty satisfaction with independent variables of income, time pressure, and items measuring control over medical and workplace issues. Compared with male physicians, female physicians were more likely to report satisfaction with their specialty and with patient and colleague relationships ( P < .05), but less likely to be satisfied with autonomy, relationships with community, pay, and resources ( P < .05). Female physicians reported more female patients and more patients with complex psychosocial problems, but the same numbers of complex medical patients, compared with their male colleagues. Time pressure in ambulatory settings was greater for women, who on average reported needing 36% more time than allotted to provide quality care for new patients or consultations, compared with 21% more time needed by men ( P < .01). Female physicians reported significantly less work control than male physicians regarding day-to-day aspects of practice including volume of patient load, selecting physicians for referrals, and details of office scheduling ( P < .01). When controlling for multiple factors, mean income for women was approximately $22,000 less than that of men. Women had 1.6 times the odds of reporting burnout com

Background and *** physical therapists depend on their professional journals for high-quality evidence. The purpose of this study was to evaluate the rigor of research and review articles in 4 national physical therapy *** and *** articles in 6 consecutive issues of theAustralian Journal of Physiotherapy,Physical Therapy,Physiotherapy, andPhysiotherapy Canada, published between January 2000 and June 2001 (N=179), were reviewed. One trained reviewer identified the type and purpose of each article and assessed the rigor of treatment and review articles according to explicit *** majority of articles reviewed were original studies (56%). The majority of the research articles that dealt with human health care (66%) addressed topics that were not directly applicable to the provision of patient care such as measurement topics and studies on subjects without identified pathologies or impairments. Of the 179 journal articles, 19 met the standards for rigor (11%). The majority of these articles dealt with treatment. The pass rate per journal was as follows:Australian Journal of Physiotherapy, 10% (4/42);Physical Therapy, 15% (7/47);Physiotherapy, 12% (4/34); andPhysiotherapy Canada, 7% (4/56).*** such a small percentage of articles in these professional journals were identified as having direct application to patient care, physical therapists should attempt to access other sources of information to find additional high-quality evidence. A larger sample with a greater number of issues per journal may have yielded different results and indicated different trends, and further research appears to be warranted.

The Ireland - Northern Ireland - National Cancer Institute Cancer Consortium was established to improve clinical cancer services and patient care on the island of Ireland, and to foster joint collaboration in cancer research and development. An important part of this Consortium was to develop telemedicine systems to facilitate collaboration between participating partners. We have implemented a telemedicine environment for the Consortium based on the TELESYNERGY/spl reg/ Medical Consultation Workstation developed at the U.S. National Institutes of health. The collaborative use of the system at the three sites has led to the improvement in quality of care in that each patient, regardless of location, can receive an expert assessment and given optimal therapy. The system will be a platform for collaborative clinical and translational research. In the future, this technology will be implemented at additional sites and applied to other medical specialties including cardiology, radiology, and infectious diseases.

作者： Duong, Diep N. Ryan, Rebecca Vo, Dai T. Tran, Thuan T. Uniformed Services University of the Health Sciences TriService Nursing Research Program Bethesda MD 20814 4301 Jones Bridge Road United States University of South Alabama College of Nursing Mobile AL United States Texas Tech. Univ. Hlth. Sci. Center Department of Internal Medicine Odessa TX United States University of Medicine and Pharmacy Fac. of Nursing/Medical Technology Ho Chi Minh City Viet Nam

The purpose of the present descriptive study was to determine the risks associated with hypertension in Vietnamese communities around Ho Chi Minh City, Vietnam. The 357 volunteers for this health promotion screening consisted of 125 men and 232 women, 19-85 years of age. Participants completed surveys on their cardiovascular health history, health practices and hypertension knowledge. Nearly one-third of the sample was found to have systolic blood pressure (SBP) above 139 mmHg and/or diastolic blood pressure (DBP) above 89 mmHg. Fifteen participants had either SBP over 180 mmHg or DBP over 108 mmHg, nine of these 15 participants were taking antihypertensive drugs and 76 were taking other cardiac medications. The majority (98%) cooked with salt and 75% added salt when eating. Drinking alcohol (21%) and smoking (23%) were more common in male participants. Knowledge of cardiovascular risks was very low, indicating a need for community health promotion activities with educational campaigns and further screenings.

Dr. Toy concluded the meeting by summarizing the major controversial issues highlighted by the speakers. PABD PABD is, in principle, a safe and effective method for avoiding exposure to allogeneic blood in appropriate circumstances, and a substantial amount of clinical literature has been published to support its role. However, additional research is needed in the following areas: The optimal number of units that should be collected for specific surgical procedures to ensure maximum savings in use of allogenic blood and minimum wastage; The safety of PABD in patients, including a better understanding of which patients are at risk for complications, what the risks are, and what alternative collection strategies should be employed. Adequate control groups are needed in these studies; A definition of the transfusion trigger as it applies to autologous RBCs; An investigation of the role of rEPO in facilitating PABDs; The development of better collection logistics (e.g., double-unit collections) and storage protocols (e.g., improved additive solutions); and Additional studies of the costs associated with autologous blood collection and development of more cost-effective strategies. Acute normovolemic hemodilution Much of the published literature related to hemodilution describes the concept and specific protocols; in contrast, relatively little clinical research relating to the efficacy of this technique exists.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this study was to examine the consistency of measurements of maximal isometric force production in children using an electronic strain gauge. A standardized protocol of force testing from the Tufts Quantitative Neuromuscular Examination was adapted to obtain isometric force measurements in seven muscle groups bilaterally. Ten children with Duchenne's muscular dystrophy (Dmd) and 10 age-matched children without Dmd were recruited for the study. A generalizability framework was used to examine variations in measurements attributable to group differences, test occasions within the same day, and extremity side. Intertester reliability estimates were also completed on a subsample of children with and without Dmd. A three-way analysis of variance between groups, sides, and test occasions demonstrated a significant group main effect for all muscle groups. In general, significant main effects were not present for side or test occasion. Test-retest intraclass correlation coefficients (ICCs) for all muscle groups ranged from .88 to .99 for the children with Dmd and from .85 to .98 for the children without Dmd. Intertester ICCs were slightly lower, ranging from .74 to .97 for the children with Dmd and from .71 to .98 for the children without Dmd. The results indicate that the electronic strain-gauge protocol produces reproducible force measurements in seven selected muscle groups in children with and without Dmd.
