目的 研究化工工人肌肉骨骼功能状况及其与工作能力的关系。方法 对101名化工作业工人进行肌肉骨骼功能(背肌耐力、手握力、躯干柔韧性、腹肌力和肌肉骨骼功能指数)测定和工作能力指数(wAI)测定。结果男性握力显著高于女性(P<O.01),腹肌力、背肌耐力和肌肉骨骼功能指数(MSFI)均男性较高,躯干柔韧性女性较高;年龄与MSFI呈负相关(r=O.489,P<O.01),随年龄增加,肌肉骨骼功能下降;不同劳动类型化工职工肌肉骨骼功能差异无显著性;肌肉骨骼功能与工作能力之间存在密切的关系,MSFI与WAI的相关系数为O.215(P<O.05),MSFI分级和WAI分级间有较好的一致性,完全一致率为56.7%。结论 肌肉骨骼功能的测定对于评价化工工人工作能力可能具有重要的意义。 相似文献

The argument for pharmaceutical policy 总被引:1,自引:0,他引:1

In this article the authors deal with issues of drug utilisation from a clinical and policy perspective. They address the difficulties of managing drug therapy on a population level, which is known among professionals, as the problem of rational use of medicines. Various definitions and interpretations are presented and compared. This is followed by a presentation of the concerns associated with pharmaceutical marketing from a policy perspective, including the fear that the dominance of information produced by industry may lead to irrational drug use. Next, the authors review the tools for policy making including educational, managerial, and regulatory interventions. The (often overlapping) concepts of medicines management, clinical pharmacy and pharmaceutical care are then discussed to show how professionals, sometimes in collaboration with policymakers, have tackled the problem of nonrational use of medicines. The authors address the question as to whether the rational use of medicines a universal concept, whether it can be and whether it should be? They argue that, as with most concepts, the rational use of medicines must always be viewed in context. They conclude that pharmacy needs to adapt its way of thinking to include the issue of context. They point out that clinical pharmacists today already adapt their decisons to each patient and patient group. Policymakers are encouraged to adopt a similar approach because populations as well as particular market situations vary and therefore policy solutions cannot be considered universal.*This article is the second in a series of articles on this topic that will appear in Pharmacy World & Science during 2005. 相似文献

It has been argued in previous issues of this journal that health technology assessment can be used as a tool to assess the efficiency of pharmaceutical care by linking its impact on clinical and humanistic outcomes to the resources required to achieve these outcomes. Additionally, as policy-makers appreciate the need to evaluate projects on the basis of their costs and benefits, the application of health technology assessment to pharmaceutical care may serve as a way of communicating with policy-makers and informing policy on pharmaceutical care.This article elaborates on this idea by arguing that policy-makers will be more likely to appreciate the value of pharmaceutical care if researchers pay more attention to some methodological principles underlying health technology assessment in the context of pharmaceutical care, and if they take into account the decision-making context facing policy-makers. In order to raise the methodological quality of studies, researchers need to take care to define better the pharmaceutical care intervention; to evaluate the costs of the intervention and its impact on the utilization of other health services; and to aggregate the various clinical and humanistic outcome measures that are commonly used in this type of research. In order to increase the usefulness of study findings to policy-makers, researchers need to identify the multiple objectives that policy-makers pursue, and show how study findings will aid policy-makers in attaining these objectives. 相似文献
