医疗卫生服务价格改革方向初探

医疗卫生服务价格改革是要理顺价格构成成份之间量的关系，使每个构成成份的价格值都在供求关系的约束中，在政府的有效管制中，从而成为医疗卫生资源合理配置的有效工具。为此：①对生产要素分别定价；②对劳动定价；③对资本和自然资源定价；④确定医疗卫生机构内部管理时劳动价格；⑤价格中的所有构成成份价格都置于供给和需求关系约束下；⑥确定医疗卫生服务价格的理想传递方式。     

亚胺培南/西司他丁与头孢他啶治疗中、重度细菌感染疗效费用分析比较研究

对我院４５例确诊为中、重度细菌感染住院患者进行了亚胺培南／西司他丁与头孢他啶疗效费用分析比较研究。结果表明：２组病例有效率、死亡率无显著性差异；头孢他啶组较亚胺培南／西司他丁组疗程明显延长。亚胺培南／西司他丁每日所需费用明显高于头孢他啶；治疗结束时，前者全部费用并未超过后者；全部住院费用无明显差异。作者认为：决定２种药物全部费用的因素，除与药物单价和每日费用有关，还与药物疗程密切相关。选用药物抗菌作用越强，用药时间即相应缩短，住院时间必然缩短；最终患者住院费用降低     

Laparoscopic nephrectomy is cost effective compared with open nephrectomy in a large county hospital.

BACKGROUND AND OBJECTIVES: To evaluate the experience with laparoscopic nephrectomy in a large county hospital and perform a cost comparison between uncomplicated open and laparoscopic nephrectomy. METHODS: Eleven consecutive patients who underwent an uncomplicated laparoscopic nephrectomy in a large county hospital were compared with 8 patients who underwent uncomplicated open nephrectomy during the same period. Patient charts and corresponding billing records were reviewed to determine overall hospitalization cost and individual cost components. RESULTS: No perioperative complications occurred in either the laparoscopic or open group, and no statistically significant differences existed between groups with regard to patient demographics or operative parameters. The overall operating room costs favored the open nephrectomy group by dollars 1070 (P=0.003). However, the overall cost of hospitalization, surgeon professional fees, duration of hospitalization, room and board costs, laboratory, and radiology costs, pharmacy costs, intravenous solution and infusion pump costs all significantly favored the laparoscopic patient group. The mean difference in overall hospital cost between laparoscopic and open nephrectomy was dollars 1211 in favor of laparoscopy (P=0.037). CONCLUSIONS: Our experience with laparoscopic nephrectomy in a large county hospital demonstrates a clear economic advantage in favor of the laparoscopic approach. Given limited funding for public hospitals and a clear patient benefit, laparoscopic nephrectomy should constitute first-line therapy when nephrectomy is indicated.     

北京市城市社区老年人伤害疾病负担的研究

目的 探讨北京市城市社区老年人伤害发生现状及其疾病负担。方法 以居委会为单位，采取随机整群抽样的方法，调查北京市牛街地区60岁及以上老年人在其过去一年中的受伤情况及伤后影响等。结果 被调查者在过去一年中共有311例、420人次伤害发生，涉及12种伤害。伤害总发生率（人）为13．55％，人次发生率为18．30％。因伤死亡1例。伤害的危害涉及个人、家庭、社会三个层面，包括躯体、精神、经济损失等多方面。跌倒不仅发生率最高，伤情最严重，而且经济损失最大。结论 北京市城市社区老年人群伤害发生与死亡水平位居中等水平；跌倒已经成为威胁该人群生存与健康的重要公共卫生问题。     

A comparative study of plateletpheresis using Baxter Autopheresis C and Haemonetics PCS Plus

SUMMARY. This study compared plateletpheresis on the Haemonetics PCS Plus (PCS Plus) and the Baxter Autopheresis C (Auto C) using the same 100 selected donors. The number of packs meeting UK BTS/NIBSC specification (>2.2 times 10¹¹ platelets per pack) was achieved by 99% of PCS Plus and 82% of Auto C procedures. The positive correlation found between donor precount and final platelet yield was better for the PCS Plus. Both machines met U.K. specification for white-cell contamination but this was significantly greater for the Auto C. Plasma yields were similar.
As a result of this study we chose to use the PCS Plus for routine plateletpheresis in our unit. This has enabled us not only to comply with UK BTS/NIBSC specifications for apheresis platelets easily and cost effectively but also to meet our own higher specification (2.75 times 10¹¹ platelets per pack) using existing staff and without extending the working day.

Positive clinical impressions: II. Participants' evaluations

Nine months after the residential stage of Koach, participants were asked to evaluate the program's effectiveness. Most of the veterans reported improvement in the areas queried, and especially in social relations, and nearly all of them stated that they would recommend the program to other veterans. The commander-therapists became the major source of help for these veterans following the Koach project, and about half reported that they participated regularly in self-help groups. Most of the participants acquired coping techniques that continued to serve them 9 months after the end of the residential stage of Koach. One of the more important measures of Koach was thought to be the veterans' own evaluations of the project, their assessment of the project's success in achieving its aims, and their satisfaction with it. In this article we will present the subjects' evaluations of treatment effectiveness as expressed in behavioral and emotional changes that they attributed to the treatment.     

Mammographic screening: case-control studies.

BACKGROUND: The case-control design can be used to evaluate the benefit of cancer screening programmes. MATERIALS AND METHODS: This paper outlines the main methodological features of the case-control design in this context, and indicates some potential biases. It also reviews the existing case-control literature on mammographic screening. RESULTS: Case-control studies consistently indicate a reduction of approximately 50% in breast cancer mortality associated with mammography. This result indicates greater benefit than shown in randomised trials; however, one should recognise that trials indicate effectiveness whereas case-control studies indicate efficacy. The two types of evidence are broadly compatible when one allows for screening non-compliance and contamination in the randomised trials. CONCLUSIONS: The case-control evidence supports and is consistent with the findings of randomised trials of mammography. Effectiveness estimates from trials indicate the benefit of screening to the population as a whole, and are pertinent to the public policy debate as to the value of offering screening. In contrast, case-control studies indicate benefit to actual screening participants. As such, case-control estimates of efficacy are appropriate for individual decision-making by women about their use of mammography when it is potentially available to them.     

Effect of Population Aging on the International Organ Donation Rates and the Effectiveness of the Donation Process

This study analyzed the effect of population aging on organ donation for transplants in 43 countries and on the effectiveness of the donation process by comparing the results between Spain and the United States. The percentage of the population aged 65 or over accounted for 33% of the difference in the donation rates between the countries and for 91% of the variation in the rates after age adjustment. However, the level of aging of the Spanish (16.5%) and American (12.3%) populations failed to account for the percentages of deceased donors 65 or over (28% vs. 10%), due to the different age-specific donation rates, much higher in Spain above 50 years. These differences lead to a higher effectiveness of the process in the United States (3.1 transplanted organs per donor vs. 2.5 in Spain), though at lower rates of transplant per million population (73 vs. 87). We conclude that older populations have a greater donation potential as donation rates are strongly associated with population aging. It should therefore be mandatory to adjust donation rates for age before making comparisons. Additionally, effectiveness decreases with older donors, so age should be considered when establishing standards relating to organ donation and effectiveness of the process.
