Effectiveness of a hospital-wide selective screening programme for methicillin-resistant Staphylococcus aureus (MRSA) carriers at hospital admission to prevent hospital-acquired MRSA infections

Screening of potential MRSA-positive patients at hospital admission is recommended in German and international guidelines. This policy has been shown to be effective in reducing the frequency of nosocomial MRSA transmissions in the event of an outbreak, but the influence of screening on reducing hospital-acquired MRSA infections in a hospital setting where MRSA is endemic is not yet well-documented. This study describes the effect of hospital-wide screening of defined risk groups in a 700-bed acute care hospital during a period of 19 months. In a cohort study with a 19-month control period, the frequencies of hospital-acquired MRSA infections were compared with and without screening. In the control period, there were 119 MRSA-positive patients, of whom 48 had a hospital-acquired MRSA infection. On the basis of this frequency, a predicted total of 73.2 hospital-acquired MRSA infections was calculated for the screening period, but only 52% of the expected number (38 hospital-acquired MRSA infections) were observed, i.e., 48% of the predicted number of hospital-acquired MRSA infections were prevented by the screening programme. The screening programme was performed with minimal effort and can therefore be recommended as an effective measure to help prevent hospital-acquired MRSA infections.

Situation analysis of quality of abortion care in the main maternity hospital in Hai Phòng, Viet Nam

Six months after a Comprehensive Abortion Care project was implemented in Phu-San Hospital, the main maternity hospital in Hai Phòng, northern Viet Nam, a study of quality of abortion services was carried out. The study explored the interaction between providers and women seeking abortion and how cultural values influenced quality of care. A quantitative and qualitative approach was employed: a three-part structured survey with 748 women before and after they had an abortion, 20 in-depth interviews with women just after abortion, seven informal interviews with health care staff and 100 participant observations. Both the women and the staff equated quality of care mainly with improved technical performance of abortion. Insufficient knowledge and skills had a negative impact on provision of information and good quality counselling in relation to understanding and uptake of contraception, treating reproductive tract infection and preventing post-abortion infection. To further improve abortion care in hospitals such as Phu-San, training programmes are needed that integrate counselling and clinical skills and address the cultural factors that hinder health staff and women from interacting in an equitable manner. A supportive supervisory system that holds health staff accountable for conducting high quality information and counselling sessions should also be established.     

慢性肝病合并细菌感染临床特点分析

目的 :分析慢性肝病合并细菌感染的特点。方法 :对 1997～ 2 0 0 2年住院的慢性重度、重症肝类及肝硬化合并细菌感染患者 52例进行回顾性分析。结果 :其中医院内感染占 2 9 8%。感染的部位 :腹腔感染 40 4% ,血液感染17 3 % ,呼吸道感染 18 1% ,肠道感染 9 6% ,胆道感染 7 7% ,口腔感染占 6 3 % ,其他感染占 3 3 % ,重型肝炎的感染率最高 ,其次为肝硬化和慢性重度肝炎。结论 :肝病患者免疫力低下 ,易于合并细菌感染 ,感染使病情加重 ,影响肝病的愈后 ;提高患者免疫力 ,增强控制医院感染的措施 ,重视潜伏感染状态病灶的处理 ,早期诊治感染可提高肝病患者的生存率
