RESISTANCE: Pseudomonas aeruginosa is characterized by its low intrinsic susceptibility to many antibiotics and its capacity to acquire additional resistance mechanisms to usually active drugs. Some beta-lactam resistance mechanisms are well known (penicillinase production, cephalosporinase overproduction) and others have been recently identified, such as active efflux systems, which confer coresistance to quinolones, and new beta-lactamases which are limited to a few countries (extended-spectrum beta-lactamases, imipenemase). Ceftazidime remains the most active beta-lactam agent. ACTIVE DRUGS: Among aminoglycosides, amikacin and isepamicin are the most frequently active drugs. The use of fluoroquinolones is limited by a high incidence of acquired resistance. The percentage of resistant strains is highly variable according to countries, hospitals and wards. CLINICAL PRACTICE: Therapy, usually based on a beta-lactam-aminoglycoside combination, will be empirical at first, according to local epidemiological factors, site of infection and previously administered antibiotics, then re-evaluated according to susceptibility results.
The incidence of nosocomial infections is one of the most important quality indicators in health care. It increases the economical burden, augments morbidity, lengthens hospital stay, and is associated with a high mortality rate. Infection control programs are designed to minimize such adverse events. An effective infection control program can reduce the incidence of nosocomial infections by over 30%. It is regarded as among the most cost-efficient medical interventions available in modern public health. The national law for health insurance (KVG) makes quality in health care also a legal issue. This law enforces quality assurance on a scientific basis. In Switzerland there are no national guidelines to define the nature and extent of infection control in health care institutions as in many other European countries. In the United States quality standards are part of accreditation of any health care institution. Evaluating scientific evidence and international experience this article provides the rationale for a quality standard for infection control in Swiss hospitals. It features three general rules and five elements of structural quality. The recommendations are: (1) Every hospital must have a system to control nosocomial infection in patients, care givers and visitors. (2) This program consists of defined elements of structural quality. (3) The program is permanently being improved in its quality. The basic elements are: (1) infection control committee, (2) infection control team, (3) guidelines, (4) surveillance, (5) infrastructure. The feasability and impact of this standard has to be evaluated.
OBJECTIVE: To study the spread of methicillin-resistant Staphylococcus aureus (MRSA) in hospitals, especially secondary MRSA infections in relation to the origin of the MRSA strain and the measures taken regarding contact isolation. DESIGN: Secondary data analysis. METHODS: As part of the national MRSA surveillance of the National Institute of Public Health and the Environment, data were collected using questionnaires. The analysis covered the period July 1994-June 1996 and was performed for index cases of secondary infections versus sporadic cases. Possible risk factors were determined. RESULTS: In the study period 30 index cases of (clusters of) secondary infections and 191 sporadic cases were found. The size of the clusters was limited. Strict contact isolation as described in the guidelines of the Dutch Working Group on Infection Prevention prevented secondary infections in most cases. Patients for whom no relation could be found between the MRSA infection and a stay abroad were found to have caused more secondary infections, even when the data were corrected for contact isolation measures.
