There is a need for occupational therapists to become competent managers in a diverse range of health care settings. In this paper, the author's continuing education course on management which they have conducted at the West Australian Institute of Technology (now Curtin University of Technology) over the past four years. Details of participants, their reasons for attending and their comments on the course are included. The authors emphasise the need for more continuing education in management and the provision of skills for coping with organisational life, in particular in a female dominated profession such as occupational therapy. 相似文献

Although the fact that, in general, the US population is living longer is said to be the public health success story of the 20th century, the boom in the population aged 65 years and older is having and will continue to have major implications for all age groups as well as for the nation's health, social, and economic institutions. The concept of productive aging can provide guidance in addressing these implications. The assumptions of productive aging reflect today's reality that older people are repositories of wisdom and experience and important assets for society; relatively healthy, with the potential for maintaining that condition until late in life; capable of making economic and social contributions that benefit themselves, their families, and their communities; and in need of purposeful and meaningful roles and activities in life. A productive aging activity model emphasizes involvement in paid work, volunteerism, education, fitness and exercise, leisure and travel, advocacy and political action, and consumerism. This article discusses the concept of productive aging, a related activity model, and qualitative focus group research undertaken in conjunction with the 1995 White House Conference on Aging.

Overdiagnosis, sojourn time, and sensitivity in the Copenhagen mammography screening program 总被引:1,自引:0,他引:1
The goal of this research was to estimate the overdiagnosis at the first and second screens of the mammography screening program in Copenhagen, Denmark. This study involves a mammography service screening program in Copenhagen, Denmark, with 35,123 women screened at least once. We fit multistate models to the screening data, including preclinical incidence of progressive cancers and nonprogressive (i.e., overdiagnosed) cancers. We estimated mean sojourn time as 2.7 years (95% confidence interval [CI] 2.2-3.1) and screening test sensitivity as 100% (95% CI 99.8-100). Overdiagnosis was estimated to be 7.8% (95% CI 0.3-26.5) at the first screen and 0.5% (95% CI 0.02-2.1) at the second screen. This corresponds to 4.8% of all cancers diagnosed among participants during the first two invitation rounds and following intervals. A modest overdiagnosis was estimated for the Copenhagen screening program, deriving almost exclusively from the first screen. The CIs were very broad, however, and estimates from larger datasets are warranted. 相似文献
