Summary: Summary. A study was conducted to determine whether the attitudes of medical students to death and caring changed during the 3 months following exposure to cadaver dissection. All first-year students were invited to complete a questionnaire immediately before their initial cadaver dissection experience, after 6 weeks, and after a further 3 months. The questionnaire reflected attitudes to death, violent death, death of someone known to the respondent and caring when someone known to the respondent is seriously injured. Ethnicity and previous exposure to dying has no effect on responses, but overall men students' reactions were significantly less than for women ( P < 0.001). The responses given on the final part of the questionnaire after 3 months were significantly lower than those to most questions in the first part of the questionnaire. The exceptions were those questions where the subject in the given scenario was known to the respondent, where reactions were rated significantly greater ( P < 0.001) in the follow-up questionnaire and can be explained on the basis that they were a personal referent.
Students rapidly develop a coping mechanism which enables them to view cadaver dissection as an occupation quite divorced from living human beings. During these early months of training solicitude decreases for those who die who are unknown to them, but concern for personal referents increases. Educators should be aware of the dramatic change of attitudes among students and the process of professionalization which might influence their caring of future patients.  相似文献

The use of anaesthesiologists in prehospital emergency care is controversial. We wanted to assess the impact of an anaesthesiologist and a short time interval from acceptance of a mission to take–off at survival rates in a rural/urban emergency medical service. Prospectively registered data for 991 consecutive patients through a 12–month period were retrospectively evaluated by an independent foreign expert. Of all primary missions, 3.3% were considered probably lifesaving from site of injury to receiving hospital. Of these, the lifesaving result in 50% were dependent on both the qualifications of the anaesthesiologist and a short response time. Survival from hospital admission to discharge was 44%. All patients were discharged to their own homes, able to live a fully functional life. The consistent use of anaesthesiologists compared to less qualified personnel and the maintaining of response times below presently required minima doubles the potential for lives saved in services comparable to the one studied.  相似文献

A recent large increase in Caesarean section (CS) in Italy was the initial stimulus for a study to identify risk factors for CS and, if possible, to suggest strategies to counteract the rise. The study was conducted in three hospitals where a wide range of individual variables was collected from the clinical records and from personal interviews. Crude CS rates and odds ratios were evaluated for each single variable while logistic regression has been used to investigate possible confounding factors. The study involved 1316 consecutive deliveries. Crude CS rates were 29.4%, 15.7% and 16.1%. Variables identified as high risk factors were pre-eclampsia, previous CS, breech and other non-vertex presentations. Antenatal care under an obstetrician working in the same hospital, a low number of antenatal consultations, previous miscarriages, offer (by obstetrician) and request (by women) for CS showed significantly high odds ratios (ORs). Previous live births was strongly negatively associated with CS. No relationship between type of delivery and social status was observed while a physician factor was detected in all three hospitals where rates for different physicians ranged from 0% to 52.8%. Apart from the main medical indications for Caesarean section (previous CS, breech presentation), the results seem to indicate that individual practice style may be an important determinant of the wide variation in the rates of Caesarean delivery. While this may have been suspected before this study, these results are the first hard data to indicate that, in Italy, CS is widely performed for non-medical reasons.  相似文献

大型医院病案信息化的管理与实践   总被引:3,自引:0,他引:3  
王铸 《中国医院管理》2003,23(10):27-28
病案作为医学临床信息的重要载体,只有将其进行海量存储、快速查阅、远程传输,使之活跃起来,才能真正地满足医疗、教学、科研和管理的需要。将传统的纸质病案进行扫描后保存为光盘,并存入光盘镜像服务器中,实现了网上实时访问、检索、查询、浏览和传输功能,并可以利用病案管理软件进行相应的统计和分析。为医疗信息资源进一步开发和利用,探索了一条大型医院病案信息化管理的有效途径。  相似文献
