We report results of a survey of medical equipment purchasing, utilization, and maintenance practices in 12 Chinese tertiary-care hospitals. A dramatic increase in expenditures on medical equipment was found to have occurred after 1979, mainly resulting from purchases of imported equipment. Based on survey results and on personal observations, recommendations are given for reducing equipment-related costs through the development of clinical engineering services.

Prevention of smoking in pregnancy is a mission of utmost importance since the fetal outcome is improved when the mother quits smoking. Methods to prevent smoking have to consider maternal attitudes and characteristics and be based on pedagogical and behavioral principles. A well-motivated staff, a self-help manual accepted by most women, and special support to those who want it are minimal requirements.

Drugs have a central place among medical technologies, and medical technology assessment can learn from the established regulation of drug technology. This article outlines how users' experiences are not part of the basis on which decisions are made today, although this knowledge is imperative for identifying the problems that are not uncovered or foreseen by today's drug assessments. Further, users' interests might not be part of assessments that are based on the controlled clinical trial. A framework for drug technology assessments based on a user perspective is suggested.

Among alcohol and narcotics, alcohol is most comprehensively documented as a teratogen. However, for all other narcotics, data are continuously accumulating, convincingly displaying the teratogenic effects. The proportions between “somatic” teratogenicity and “behavioral” teratogenicity vary between the different agents. Preventive work in prenatal clinics and among social workers, as well as objective mass media attention to the problem, seems to have lowered the incidence of severe fetal alcohol syndrome where the above-mentioned activities have been practiced. The female alcohol consumption in Sweden decreased from 1976 to 1985; thereafter, a slow continuous increase is underway again, in Sweden the number of recruits to narcotic abuse peaked in the 1970s and early 1980s. Thereafter, the number of recruits among females decreased, but abuse has continued among the members of the older age groups.

To determine the potential role of extracorporeal shock wave lithotripsy (ESWL) in the treatment of symptomatic gallstone patients in France, a simulation model evaluated the health and economic effects of three different treatment strategies. Decision analysis of conventional cholecystectomy alone and either of two strategies using a combination of biliary lithotripsy and conventional cholecystectomy reveals that a strategy employing biliary ESWL results in a significant number of successfully treated patients, thus avoiding the risks and costs of abdominal surgery. Moreover, cost analysis shows that expanding the use of lithotripsy to all patients for whom the procedure is indicated increases the average cost per successfully treated patient, but, more importantly, decreases the overall costs incurred by the cohort. From a societal viewpoint, a policy using biliary ESWL in appropriate patients is superior to one of cholecystectomy alone, from both clinical and economic perspectives.

Alcoholism among women has increased during the last decades. Thus it is likely that an increasing number of pregnancies will involve risk of alcohol damage to the fetus. In this article, two antenatal programs are presented to identify pregnancies at risk. Adequate alcohol information seems to be sufficient for socially drinking women, whereas alcoholic women need extensive support to abstain from alcohol. The psychosocial support was not experienced as intrusive.

This article draws on social science evidence concerning the views and experiences of those using the antenatal services. It identifies several important themes in this evidence, including the need to consider pregnancy a normal process, to provide care that is sensitive to individual circumstances and that offers continuity of care throughout the antenatal period, and the obligation on providers to assess scientifically the effectiveness of the care they give.

Three strategies for timely detection of common duct stones are examined by decision analysis: the use of intraoperative cholangiography (IOC) in ALL, NONE, or in SOME of the cases that are selected by the estimated probability of a common duct stone. Selective use of IOC is the most cost-effective option and offers a slightly lower mortality risk.
