title: Septicemia due to coagulase-negative Staphylococcus in a community hospital.
abstract: The experience with septicemia due to coagulase-negative Staphylococcus at a 623-bed primary care hospital between 1980 and 1984 was reviewed. A total of 38 episodes in 37 patients were documented; data were available on 37 episodes in 36 patients. The organism accounted for 3.8% of all cases of septicemia and 6.7% of cases of nosocomial septicemia and was associated with 0.03% of all admissions. The incidence remained stable over the 5 years. The rate of survival 28 days after the episode was 78%. Most of the episodes (31) originated from infected vascular access sites. Of the 37 isolates 15 (41%), all S. epidermidis, were slime producing. S. epidermidis accounted for 33 of the isolates; of the 33, 5 were methicillin-resistant and slime producing. Various in-vitro susceptibility testing methods and testing for beta-lactamase production yielded conflicting results. Methicillin resistance, slime production and speciation as S. epidermidis were not confirmed as virulence markers. Five patients with methicillin-resistant organisms were treated with cephalosporins, and all recovered. These findings as well as examination of the literature do not support the recommendations that laboratories report such isolates as resistant to all beta-lactam agents and that vancomycin be given in all such infections. The different case mix in community hospitals as compared with university centres results in different patterns of nosocomial infection. Since the community hospital patient population is much larger, more information on the patterns of infections in these centres is needed.
