ObjectiveTo understand the cognition and mediation tendencies of health care workers in terms of third-party mediation for medical disputes, analyze the factors influencing the trust of both doctors and patients on third-party mediation, and propose suggestions on building third-party mediation mechanisms for medical disputes. MethodsBetween August and December 2012, we made the cognition questionnaire on third-party mediation for medical disputes based on the past medical literature, and the knowledge of doctor-patient relationship as well as third-party mediation agency's organizational structure (including locations and management authorities), staffing, mediation basis, validity sources and fund ensuring. We performed the random cluster sampling survey on all health care workers in five hospitals of different levels. The original data were put into the computer for statistical analysis by SPSS 18.0. ResultsThe knowledge of health care workers on third-party mediation was high. They believed that the best place for solving medical disputes should be the court or judicial administrative department, and the management authorities should be health administrative departments. In case of mediation failure, the majority of health care staff chose to continue to solve the dispute through legal channels. For the effectiveness of mediation conclusion, most health care workers tended to believe in the form of arbitration. They thought that mediators should have professional background of medicine and law; the majority of those surveyed doctors tended to accept forensic conclusions as a basis for mediation. For determining the compensation, doctors were in favor of Applicable Regulations for Medical Malpractice. Over 40% of medical staff believed that third-party mediation should be financed by government financial allocation, and more than half of the medical staff believed that it should be paid by the insurance company. ConclusionThird-party mediation should be set in and managed by the court or judicial and administrative departments. Mediator group should be formed by professionals of law and medical sciences. In the mediation process, it is recommended that the focus of controversy should be identified by forensic identification in order to form a clear division of responsibilities and high mediation efficiency. We recommend that the government introduce in financial allocations at all levels on the basis of medical liability insurance system, and force medical institutions to purchase medical liability insurance through the regulations of law, in order to provide funding support for the operation of third-party mediation organizations. Meanwhile, medical liability insurance companies should be operated under strict supervision to avoid their interference on the mediation work.
Objective To study the relationship between the expression ratio of heat shock protein (HSP) 70 to C-fos in organs outside the brain after brain concussion and the time of injury in rats, in order to provide a new visual angle for determining injury time of brain concussion. Methods The model of brain concussion was established through free falling method. Then the rats were executed at 30 minutes, 1 hour, and 3, 6, 12, 24, 48, 96, 168, 240, 336 hours after injury. Immunohistochemistry staining of C-fos and HSP70 were used in the materials from the main organs including heart, liver, spleen, lung and kidney. All related experiment results were studied by using a microscope with image analytical system and homologous statistics. Results From 30 minutes to 6 hours after injury, the proportion of HSP70 immuno-positive cells increased slowly, while the proportion of C-fos immuno-positive cells increased rapidly, and the ratio of HSP70/C-fos positive cells was on the decline. From 6 to 12 hours after injury, the proportion of HSP70 immuno-positive cells rose continuously, while the proportion of C-fos immuno-positive cells started to decrease, and the HSP70/C-fos ratio showed a rising tendency. From 12 to 336 hours after injury, the proportion of HSP70 immuno-positive cells decreased slowly, while the proportion of C-fos immuno-positive cells decreased rapidly, and the HSP70/C-fos ratio was still on the rise. Conclusions The proportion of positive cells and ratio of the two markers in the main organs including heart, liver, spleen, lung and kidney are similar to those in the brain of rats after brain concussion. Observing the proportion of positive cells of the two markers together with their ratio in the main organs outside the brain may provide a reference for the determination of injury time after brain concussion.
Objective To study the relationship between the expression ratio of induced nitric oxide synthase (iNOS) over glial fibrillary acidic protein (GFAP) and the time of injury after brain concussion in rat, in order to acquire a new visual angle for determining injury time of cerebral concussion. Methods Eighty-five healthy Sprague-Dawley rats were divided into three groups randomly: model group (n=25), experimental group (n=55), and control group (n=5). The rats in the model group were used to confirm the attack hight to make the model of brain concussion; according to the time of execution, rats in the experimental group were then subdivided into 11 groups with 5 rats in each subgroup, and their execution time was respectively hour 0.5, 1, 3, 6, 12, 24, 48, 96, 168, 240, and 336; the rats in the control group were executed after fed for 24 hours. After the model of cerebral concussion was established through freefalling dart method, hematoxylin-eosin staining and immunohistochemistry staining of iNOS and GFAP were conducted for the brain of the rats. All related experimental results were studied by using microscope with image analytical system and homologous statistics. Results The ratio of positive expression of iNOS over that of GFAP increased gradually during hour 0.5- 3 after injury in brain (from 5.03 to 10.47). At the same time, the positive expression of iNOS increased significantly (from 14.61% to 37.45%). However, the increase of the positive expression of GFAP was not obvious. Between hour 3 and 12, the ratio began to decline to 4.98, which was still at a high level, and during the same time period, the positive expressions of iNOS and GFAP also experienced the same change pattern. Later, the ratio began to decline between hour 12 and 336 after injury (from 4.98 to 0.95). All ratios at this time were lower than those between hour 0.5 and 12. The positive expression of iNOS and GFAP both increased to a climax before declining. Conclusions The ratio of positive expression of iNOS over GFAP and the respective change pattern of iNOS and GFAP can be used as the evidence of estimating the injury time of cerebral concussion. We can use the ratio of two or more markers to provide a new visual angle for concluding the concussion injury time.
ObjectiveTo understand patients’ cognition of third-party mediation model for medical disputes, analyze the factors influencing the trust of patients on third-party mediation, and propose recommendations for building third-party mediation mechanisms. MethodsFrom November 2013 to April 2014, we referred past literature to design a relevant questionnaire on the cognition of third-party mediation for medical disputes. Patients who had reached the end of the treatment were surveyed by random cluster sampling. The raw data were put into the computer for statistical analysis by SPSS 18.0. ResultsAfter giving out 500 questionnaires, we acquired 486 effective questionnaires. The result showed that 61.52% of the patients knew of third-party mediation; 55.35% of the patients considered that thirdparty mediation should be set in and supervised by the court or judicial administrative department; if the mediation failed, 57.41% of the patients chose to resolve the dispute through legal channels, and 67.90% of the patients tended to confirm the force of mediation conclusion by arbitration; 70.58% of the patients considered that mediators should have professional background of medicine and law; 73.05% of the patients tended to take conclusions of forensic identification as the basis for mediation; 64.81% of the patients were biased to take Tort Liability Act as the basis for determining the compensation; 53.70% of the patients believed that financial allocations could solve the fund problems of third-party mediation, while 38.48% of the patients thought the funds should be provided by insurance companies; 91.15% of the patients thought the medical institutions should purchase medical liability insurance, and 54.32% of the patients thought insurance companies should not intervene the process of meditation. Conclusions Government should provide financial allocations to ensure the funds of third-party mediation. Besides, medical insurance should be brought in as a supplement. Medical institutions should purchase medical liability insurance to solve problems caused by medical disputes. Third-party mediation should be set in and supervised by the court or the judicial administrative department. Mediators should have professional background of medicine and law. Conclusions of forensic identification should be the basis for third-party mediation.
