对住院病人医疗服务评价及需求的调查分析

目的 考查医院现有服务结构的合理性和病人对医疗服务的需求。方法 对作者所在医院19个临床科室年龄15岁以上的130名病人进行问卷调查,医疗服务评价内容包括:(1)医院饮食、卫生状况;(2)收费合理性;(3)收费透明度;(4)病人总体满意度。医疗服务需求包括:(1)出院后服务;(2)药物类型;(4)病房类型(4)收费透明度;(5)知情选择。结果(1)医疗服务评价:87.4%病人对卫生状况满意,513%病人认为收费合理,6．7%病人认为收费不合理;37.2%病人认为收费透明度高,8.3%病人认为收费透明度低,大部分病人希望住院部每3~5 d给一次费用报告单;82．8%病人对医疗服务感到满意。表明医疗服务的综合质量虽然得到了病人的普遍赞同,但在饮食服务、收费透明度和收费合理性方面仍有待提高。(2)医疗服务需求:91.3%病人希望出院后一定时间内可免费看门诊或叶通过电话向主管医生咨询有关疾病防治、保健等问题;73．8%病人希望用合资企业生产的或国产药物,26．2%病人喜欢用进口药,仅11.3%病人认为药物越贵治疗效果越好;喜欢住50-70元双人间的病人占40．8%,愿意住30-50元多人间和90~120元单人间的病人比例分别为359%、23.3%;调查人群入住单人间、双人间与多人间的比例为2:39:59,病人需求的理想病房结构是36:41:23．矛盾突出在现在的人间设置得     

The structure of memorized knowledge in students and clinicians: an explanation for diagnostic expertise

This paper provides for the first time evidence of a consistent difference in the memory structures of novice and expert clinicians. The diagnostic performance of first- and third-year clinical medical students, senior house officers, registrars and consultants on four clinical problems in general medicine was studied. Comparisons were made of all diagnostic interpretations offered and the forceful features (personally important pieces of information which act as a key to particular memory structures which in turn give rise to the clinical interpretation) from which these were derived. Results demonstrate that the numbers of interpretations made and the numbers of forceful features identified did not differ significantly between groups (P greater than 0.05). However, the actual interpretations made in three out of four cases, and the actual forceful features identified in all cases, did differ significantly between groups (P less than 0.05). The numbers of interpretations made by all groups were large and demonstrated enormous variability. Highly individualized multiple responses to clinical information are associated with easy diagnoses. We conclude that there is no difference between groups of differing clinical experience in the breadth of thought but that there are marked differences in the precise content and structure of thought. This allows coherent explanation of variation in diagnostic expertise with clinical experience. The significance of the findings is discussed.     

浙江省台州市路桥区从业人员乙肝病毒标志物检测的调查分析

目的：了解路桥地区2004年至2006年之间,从业人员健康人群HBsAg、HBsAb的阳性率及大、小三阳所占的比例。方法：对32 490人来体检的健康人群进行乙肝三系二对半检测,采用酶联免疫法（ELISA）测定HBsAg、HBsAb、HBeAg、HBeAb、HBcAb,按不同性别、城区与乡镇之间、两年之间进行比较。结果：不同性别之间HBsAg、HBsAb的阳性率无显著性差异。城区与乡镇之间HBsAg、HBsAb阳性率有显著性差异。两年之间HBsAg的阳性率有下降趋势。大小三阳的比例在各组之间也各不相同。结论：健康人群的乙肝病毒携带率比例偏高,易感者多,相关部门应督促乙肝疫苗的注射,减少乙肝发病率。     

高等医学院校医学化学教材改革的几点思考

医学的发展已进入分子水平，医学生必须具有扎实的化学基础才能适应专业学习及临床、科研工作的需要。现行医学化学教材大多沿用几十年前的模式，部分内容陈旧滞后，实用性不强。面对现实，改革势在必行。我们认为，突出重点、注重实用、体现医学特色应作为改革的方向。     

医学生营养知识与膳食状况调查

①目的了解医学生营养知识的掌握情况及对教育传播方式的需求意见，以加强营养知识教育，改善大学生的健康素质。②方法对762名在校大学生进行问卷调查。③结果医学院在校生对营养知识及常识掌握深度和广度都不够，但渴求得到营养知识的欲望比较高，对营养知识的重要性认识正确。有73．6％的学生认为营养知识对生活很重要。87．2％的学生愿意接受营养知识的教育，对营养知识教育的传播方式也表现出特有的需求意向。大学生的膳食结构不够合理，奶类、薯类、鱼虾禽类、豆制品摄入不足。④结论应加强医学生营养知识教育，使医学生做到科学合理的安排膳食，改善饮食行为，促进身体健康。     

医疗纠纷尸检86例法医学分析

目的：以法医学观点分析讨论医疗纠纷尸检的意义和重要性。方法：从本系1993年－2001年9月尸检资料中选出涉及医疗纠纷的86例资料，经驻表格逐一登记，分类整理，最后进行分析。结果：医疗纠纷的发生率逐年增多，且多集中于儿科（20例，23.2%)、产科（19例，22.1%)、内科（16例，18.6%)、诊所（10例，11.6%)、外科（9例，10.5%)等。医疗纠纷多与院内猝死、难以避免的并发症死亡、临床诊断不清、误诊、误治及医务人员态度不好等有关。结论：医疗纠纷的发生与许多因素有关，法医受理医疗纠纷尸检在程序上有利于取得社会公信，并有利于纠纷的最终解决。     

Development and implementation of an innovative intern training programme

The quality of medical education during internship is a cause for concern. This paper describes a structured educational programme for interns that was based around learning modules, clinical attachments and bedside teaching. The programme was incorporated into the term rotation of interns within an Area Health Service, and evaluated. Learning modules were timetabled by a Programme Coordinator and interns were reminded to attend. Clinical attachments were organized by the interns from a list of willing supervisors. Attendance at timetabled learning modules averaged 67%, which was greater than the 27% attendance at clinical attachments. Both sessions received high ratings for quality and clinical relevance. This structured education programme was based upon adult learning methods and was both feasible and well received by interns. Intern training programmes need to be programmed into the working week to ensure attendance, and modified following evaluation by interns. Such programmes should be considered by all hospitals to which interns are allocated.     

Eligible Veterans'' Choice Between VA-covered and Non-VA-covered Dental Care

Veterans who were eligible for dental care in Department of Veterans Affairs (VA) facilities at no monetary cost responded to a mailed questionnaire. Seventy-one percent were aware that they were actually eligible for VA dental care. However, only 48 percent reported the VA as their only or primary source of dental care. Eligibility status, perceived quality of VA dental care, use of VA medical care, perception that one's income meets expenses, and perceived need for dental care were significant correlates of using the VA as one's current source of dental care. Level of formal education, perception that one's income meets expenses, transportation pattern, geographic distance from a VA facility, and eligibility status were significant correlates of using the VA as one's current medical care source. Research on VA utilization offers the opportunity to study issues of access to, and use of, a large public health care system whose patients largely receive care at no monetary cost. Veterans' use of VA dental and medical care is apparently influenced by a wide variety of factors, ranging from barriers to access to non-VA systems, to characteristics of the VA delivery system itself, to need for treatment.
