The demand for home care in the Netherlands is growing and changing. A decreasing rate of institutionalization, combined with an increasing number of elderly people with special age-related, often complex health problems, has led to new groups of patients, to be cared for in their home settings. This requires a strong coordination of services between suppliers from the primary and secondary health care sectors. In order to promote coordinated care, Dutch health care providers are building inter-organizational networks. The development of such arrangements was the target of 12 demonstration projects, selected by the Ministry of Health for the National Home Care Programme. This article presents some of the results of an evaluation study of the Programme, with special attention given to the question of the extent to which such inter-organizational networks contribute to the balance between quality and cost.  相似文献

ABSTRACT: This study aimed to describe the establishment of a new University Department of Rural Health (UDRH) in South Australia and to report early achievements. In May 1997, the UDRH was established, key staff were recruited, infrastructure was developed and in April 1998 a Joint University Committee on Rural and Remote Health was formed. By mid-1999, 14 full-time equivalent staff were employed in Whyalla and Adelaide. Early achievements include: review of undergraduate rural placements; increased rural clinical placements by 1000 student-weeks; partnership with the Dental School resulting in training opportunities and falling public dental waiting lists; multidisciplinary teaching practices in four rural sites; priority public health projects established; competitive research grants won; and a capital grant to strengthen Aboriginal health services infrastructure secured. These early achievements demonstrate UDRH potential to have a real impact on health worker education, service delivery, and public health status in rural and remote areas. This strong foundation must now be built on.  相似文献

This article reviews the composition and characteristics of the health professions, the demographics of the national population, and factors that influence access to health care and satisfaction with care for ethnic/racial minority populations in the United States. In addition, an overview of publicly funded US health insurance programs for the poor is provided along with a discussion of the impact that managed care is having on the American health care system. Finally, the paper summarizes conference discussions regarding the problems, strategies, and approaches that the UK and the US have experienced with respect to providing quality health care for ethnic/racial minority populations.  相似文献

Jilek-Aall L 《Epilepsia》1999,40(3):382-386
Epilepsy when manifested as grand mal seizure provokes strong and ambivalent feelings in those witnessing it. Terms such as morbus sacer, denoting both a sacred and demoniac condition, or folk names indicating divine punishment, have expressed these feelings in European societies from antiquity to the Middle Ages and beyond. An atmosphere of fear, shame and mysticism surrounds epilepsy even in our days in many non-Western and also in Western cultures. In the course of work and studies in Tanzania, where I organized the Mahenge Clinic for Epilepsy in 1960, and in other parts of Africa, I found that epilepsy is conceived of as an "African' affliction, a manifestation of supernatural forces that makes it difficult to reach epilepsy sufferers with modern medical treatment. Epilepsy is traditionally looked on as caused by ancestral spirits or attributed to possession by evil spirits. It is also thought to be due to witchcraft, and "poisoning," and often taken to be contagious. Epilepsy may, under Christian missionary teaching, have come to be considered as due to demoniac possession or divine punishment for sins, in accordance with biblical examples. In many parts of Africa, syncretic amalgamation of indigenous traditions with Judeo-Christian doctrines influenced popular attitudes toward epilepsy. We demonstrated that persistent efforts at health education in the context of organized treatment of epilepsy can result in a change of popular notions about epilepsy and consequently lead to significant improvement in the quality of life of epilepsy sufferers.  相似文献

Objective

To examine the association between previous radiation exposure and idiopathic perifoveal telangiectasis (IPT).

Design

A multicentered, individually matched, case-control study design was used.

Participants/controls

Sixty-five case subjects were matched with 175 control subjects. Individuals with unequivocal evidence of angiographically confirmed IPT were included as cases. Control subjects were matched for center, age, and gender.

Main outcome measure

The main exposures of interest were a history of therapeutic head or neck irradiation and environmental radiation exposure.

Methods

A standardized questionnaire was administered to case and control subjects. Data were collected for the main exposures of interest as well as pertinent covariates. Conditional logistic regression was used to evaluate therapeutic and environmental radiation as risks for IPT.

Results

On univariate analysis, head or neck irradiation was associated with IPT (odds ratios [OR] = 4.15, 95% confidence interval [CI] = 1.30–13.24). While controlling for diabetes and family history of diabetes, IPT was found to be associated with both head or neck irradiation (OR = 4.06, 95% CI = 1.20–13.76) and with environmental irradiation (OR = 6.73, 95% CI = 1.06–42.74).

Conclusions

This study presents a previously unreported association between prior radiation exposure and IPT.  相似文献

This article reports on a retrospective study of 59 joint placements of siblings in foster homes, involving a total of 137 children. An overall picture is presented of the agencies' considerations in making these placements. The number of prematurely terminated placements in this group amounted to 14 (23.7%). Several factors that appear related to premature termination are discussed.Frits Boer is a university lecturer in the Department of Child and Youth Psychiatry at the University of Leiden in the Netherlands and works as a child psychiatrist at the Academic Center for Child and Adolescent Psychiatry Curium in Oegstgeest.
