Outbreak of multiply resistant Staphylococcus aureus in a pediatric intensive care unit after consolidation with a surgical intensive care unit.

Patients in a pediatric intensive care unit were placed with patients in an adult surgical intensive care unit (SICU) in a large, 12-bed room previously occupied exclusively by the adult patients. The occurrence of multiply resistant Staphylococcus aureus (MRSA) in pediatric patients increased from zero cases during the preceding 12 months to seven cases (p less than 0.001) for the 95 days that the units were combined. The rate of acquisition of MRSA by the patients in the SICU remained unchanged. Pediatric patients who acquired MRSA had longer lengths of stay (p less than 0.001) and underwent more surgical (p less than 0.01) and invasive procedures than did pediatric patients who did not acquire MRSA. Removal of the pediatric patients to their own unit returned their rate of MRSA acquisition to the previous low level.

Impact of a rigid, puncture resistant container system upon needlestick injuries.

Needlestick injuries in a 720-bed tertiary care hospital were analyzed before and after the introduction of a rigid, puncture resistant, needle disposal system. Following implementation of the system, disposal-related injuries decreased from 0.9 per 100 full-time equivalent employees/year to 0.3 per 100 full-time equivalent employees/year (p less than .005). However, needlesticks associated with procedures (2.2 vs. 4.4 per 100 full-time equivalent employees/year, p less than .0005), and those resulting from loose needles (0.5 vs. 1.9 per 100 full-time equivalent employees/year, p less than .0005), increased. Injuries occurring during needle recapping or the carrying of needles were not significantly altered. Total needlestick injuries increased from 6.0 to 8.7 per 100 full-time equivalent employees/year (p less than .0005). We concluded that a rigid, puncture resistant, needle disposal system can reduce disposal-related needlestick injuries, but must also be perceived as convenient to impact substantially upon needlesticks associated with other activities.

Strict versus modified isolation for prevention of nosocomial transmission of methicillin-resistant Staphylococcus aureus.

Patients colonized or infected with methicillin-resistant Staphylococcus aureus (MRSA) in a Surgical Intensive Care Unit and Surgical Intermediate Care Unit were placed either in Strict Isolation or cared for with modified isolation precautions. The assignment was determined by the unit in which they were hospitalized. Units were changed from one form of isolation to the other and served as their own controls. Over a 4-month study period, the rate of MRSA transmission did not change when the type of isolation precautions were altered. The ratio of colonized to infected patients also remained constant. Infected patients were usually first detected by clinical specimens, while colonized patients were usually detected by surveillance cultures performed under the study protocol. Following the study, all hospitalized patients with MRSA were placed in modified isolation precautions. Total new acquisitions of MRSA in the hospital have decreased over the subsequent 6-month period.
