Epidemiology and prophylaxis of the hospital contamination of medical personnel with viruses of hepatitis B and C

Medical personnel is one of the main risk groups with respect to hospital infections for which hepatitis B and C are professional pathology. The degree of the risk of contamination of the personnel greatly depends on the character, urgency and duration of professional activity, accuracy in following the rules of personal safety while working with infected material, the proportion of patients contaminated with viruses of hepatitis B and C in specialized departments, the epidemiological danger of therapeutic and diagnostic methods, the possibility of reliable disinfection and sterilization of the equipment. In the system of measures aimed at preventing the infection of the medical personnel a special role belongs to the specific immunoprophylaxis of hepatitis B. Prolonged experience in the immunization of the medical personnel of a big hospital demonstrates a high immunological and epidemiological efficiency of the use of vaccine against hepatitis B, produced by the Research and Manufacturing Complex "Combiotech", Russia.     

医疗损害鉴定制度的改革与发展

医疗损害指因医疗机构及其医务人员的故意或过失（即医疗过错）,造成就医患者身体上或精神上的损害结果。医疗损害鉴定是指医疗机构及其医务人员在日常医疗行为中存在法定过错并造成患者人身损害而导致的医疗损害民事诉讼,人民法院针对医疗技术的高风险、高技术等问题对外委托的鉴定。其内容主要针对医疗行为整个过程的审查和分析,对照卫生行政法规、部门规章诊疗护理规范及常规,判定医师有无过错,医疗过错行为与损害结果之间是否存在因果关系,医疗过错行为在损害结果中的责任程度以及人体损伤残疾程度等方面。

Multiple vaccinations,health, and recall bias within UK armed forces deployed to Iraq: cohort study

Objective To assess the relation between self reported number of vaccinations received and health, and between numbers of vaccinations recorded from individuals’ medical records and health.Design First phase of a cohort study.Setting UK armed forces personnel.Participants 4882 randomly selected military personnel deployed to Iraq since 2003 and a subset of 378 whose vaccination records were accessed.Main outcome measures Psychological distress, fatigue, symptoms of post-traumatic stress disorder, health perception, and multiple physical symptoms.Results Personnel who reported receiving two or more vaccinations on a single day were more likely to report symptoms of fatigue (adjusted risk ratio 1.17, 95% confidence interval 1.05 to 1.30), show caseness according to the general health questionnaire (1.31, 1.13 to 1.53), and have multiple physical symptoms (1.32, 1.08 to 1.60). These associations were no longer significant when number of vaccinations recorded in individuals’ medical records was used as the independent variable.Conclusions Multiple vaccinations given to personnel in the UK armed forces in preparation for deployment to Iraq are not associated with adverse health consequences when vaccinations are recorded objectively from medical records. Adverse health consequences associated with self reported multiple vaccinations could be explained by recall bias.     

Military nutrition: maintaining health and rebuilding injured tissue

Food and nutrition are fundamental to military capability. Historical examples demonstrate that a failure to supply adequate nutrition to armies inevitably leads to disaster; however, innovative measures to overcome difficulties in feeding reap benefits, and save lives. In barracks, UK Armed Forces are currently fed according to the relatively new Pay As You Dine policy, which has attracted criticism from some quarters. The recently introduced Multi-Climate Ration has been developed specifically to deal with issues arising from Iraq and the current conflict in Afghanistan. Severely wounded military personnel are likely to lose a significant amount of their muscle mass, in spite of the best medical care. Nutritional support is unable to prevent this, but can ameliorate the effects of the catabolic process. Measuring and quantifying nutritional status during critical illness is difficult. A consensus is beginning to emerge from studies investigating the effects of nutritional interventions on how, what and when to feed patients with critical illness. The Ministry of Defence is currently undertaking research to address specific concerns related to nutrition as well as seeking to promote healthy eating in military personnel.     

Assessment of platelet function in patients with stroke using multiple electrode platelet aggregometry: a prospective observational study

The Qatari law, as in many other countries, uses brain death as the main criteria for organ donation and cessation of medical support. By contrast, most of the public in Qatar do not agree with the limitation or withdrawal of medical care until the time of cardiac death. The current study aims to examine the duration of somatic survival after brain death, organ donation rate in brain-dead patients as well as review the underlying etiologies and level of support provided in the state of Qatar. This is a retrospective study of all patients diagnosed with brain death over a 10-year period conducted at the largest tertiary center in Qatar (Hamad General Hospital). Among the 53 patients who were diagnosed with brain death during the study period, the median and mean somatic survivals of brain-dead patients in the current study were 3 and 4.5 days respectively. The most common etiology was intracranial hemorrhage (45.3%) followed by ischemic stroke (17%). Ischemic stroke patients had a median survival of 11 days. Organ donation was accepted by only two families (6.6%) of the 30 brain dead patients deemed suitable for organ donation. The average somatic survival of brain-dead patients is less than one week irrespective of supportive measures provided. Organ donation rate was extremely low among brain-dead patients in Qatar. Improved public education may lead to significant improvement in resource utilization as well as organ transplant donors and should be a major target area of future health care policies.

Rubella Epidemic in a Maternity Unit

Four cases of rubella, the last confirmed by laboratory tests, occurred among the nurses of a large obstetric unit. Immediate measures were taken to prevent the spread of the infection to pregnant patients and staff, and none was in fact infected.Persons susceptible to rubella and who become infected may pose a real danger to women in early stages of gestation during the incubation period. We recommend that the immune status of medical and nursing personnel working in obstetric departments should be ascertained serologically, and that rubella vaccine should be offered to those who are susceptible.     

Evaluation of the probability of the infection of medical personnel with Crimean-Congo hemorrhagic fever virus in cases of introduction of the infective agent to a non-endemic territory of Russia

The data on the secondary cases of infection with Crimean-Congo hemorrhagic fever (CHF) virus during the period of 1960 - 2002 have been analyzed and the probability of the infection of medical personnel with this virus has been evaluated. The data obtained in this study may be used in the development of the mathematical model of CHF epidemics (outbreaks), taking into account not only the transmission of the infective agent, but also hospital infection, as well as for calculating the number medical personnel, necessary for the liquidation of CHF epidemics (outbreaks).

Delivery of medical care in an urban core

Seventy-six families who had an annual income under $3000, and who lived within half a mile of a medical centre were interviewed in their own homes. Their attitudes and opinions towards health care delivery service, family health and medical personnel, were obtained. They were found to be well aware of the freedom of choice which they possess by virtue of their medical registration certificate and the majority chose to go to private physicians for their care. As high as 55% of the consumers were chronically afflicted. Of these, 65% made medical visits every six weeks, and 20% went weekly. Forty per cent made well-care visits, and only 5% received no care at all. The data demonstrate a degree of satisfaction with, and acceptance of, health delivery service in this specific urban area.

THE ROLE OF GOVERNMENT IN MEDICINE

On the fundamental question of how far a government should be involved in health services, the author believes these things can appropriately be said: The government should continue to assume complete control over public health measures, and public health officials could well be permitted to invade medical services insofar as is necessary to achieve public health ends.To assist in the production of medical personnel, it is also fitting for the government to provide for increased teaching facilities, higher salaries for teachers in the medical field and scholarships for worthy students.In the area of insurance and prepayment plans, a really intelligent supervision of such devices, with the exercise of no more arbitrary governmental power than is now used by the various other regulatory commissions, is a suitable governmental function. The government''s buying policies for its wards, rather than providing direct medical services for them, should be encouraged. This would give the private practice of medicine a boost and would improve the quality of medical care. Government should encourage the regionalization of medical services with as much of the actual controls exercised at the local level as can be achieved. Private means should be utilized for the provision of these services and public means should be used for their payment when this is an obligation of the government.The problem of mass education in health matters should be tackled by government. It would be a fine thing if the medical profession and governmental agencies could agree upon delineation of their respective roles in the health field.Because further experimentation is needed before the ideal solution is found, both government and organized medicine should encourage the exploration of new approaches.     

The physician-administrator as patient: distinctive aspects of medical care

This article examines distinctive aspects of medical care experienced by a 55-year-old hospitalized for quintuple coronary artery bypass surgery who was also a senior physician-administrator (chief of gastroenterology) at the same hospital. The article describes eight distinctive aspects of administrator-physicians as patients, including special patient treatment; exalted patient expectations by hospital personnel; patient suppression of emotions; patient denial; self-doctoring; job stress contributing to disease; self-sacrifice to achieve better health; and rational medical decisions when not under stress. Health-care workers should recognize how these distinctive aspects of medical care and behavior affect administrator-physicians as patients, in order to mitigate their negative effects, potentiate their positive effects, and optimize the care of these patients.
