We undertook a study of postdischarge infections to assess the reliability of a surgical wound surveillance program in a 930-bed teaching hospital. During a six-month period, a subset of operations performed each day was randomly selected and patients interviewed by telephone one month postsurgery using a standard set of questions. The infection rate for all patients contacted directly postdischarge was 5.4%, whereas the surgical wound infection rate determined for all procedures through the standard hospital program was 1.5%. For day-surgery patients, who are not routinely followed in the hospital surveillance program, 8 (7.8%) of 103 patients contacted had infection. Thus, the overall surgical infection rate determined in this study was over three times higher than that calculated using standard surveillance. A reliable method for identifying postdischarge wound infections is necessary to ensure accurate surgical wound infection rates.

Cefixime, a broad-spectrum, orally active cephalosporin, was more active in vitro than ampicillin, cefaclor, cephalothin, and trimethoprim/sulfamethoxazole against 194 nosocomial pathogens of the family Enterobacteriaceae. Activity was especially good against Klebsiella spp, Proteus spp, Serratia spp, and Providencia stuartii. Although gentamicin had equivalent or better activity against Citrobacter spp, Enterobacter spp, Escherichia coli, and Morganella morganii, all 23 of the gentamicin-resistant strains studied were susceptible to Cefixime. Isolates tested were from urinary tract infections, abdominal infections, wounds, vascular infections, and respiratory infections; they were sequentially collected nosocomial pathogens from a single institution. This orally active cephalosporin should be considered for therapy of a variety of nosocomial infections involving gram-negative bacillary pathogens.

The risk of nosocomial pneumonia following emergency or urgent endotracheal intubation was studied prospectively. Pneumonia developed in 35 of 78 (45%) patients within three days of intubation. No differences in age, sex, underlying illness, respiratory infection, or antibiotic use were found between those with or without pneumonia. There were also no differences in the frequency of complications occurring during intubation. Patients developing pneumonia tended to have the same organisms isolated from the sputum at the time of intubation and at the time of diagnosis of pneumonia (9 of 20 were identical, 5 differed by a single organism). Sputum cultures taken at the time of intubation were helpful in predicting the subsequent pathogens in patients who developed pneumonia. There were no differences in mortality between patients with (29%) and without (28%) pneumonia. Emergency endotracheal intubation appears to contribute to the overall incidence of nosocomial pneumonia.

A one-year prospective study of surgeon-specific nosocomial infection rates was done in two community hospitals. Hospital A (93 beds) and Hospital B (158 beds) have nearly identical surgical staffs. Unified criteria for the diagnosis of infections, methods of data collection, and coding were used. Data were processed with an IBM 370 computer using Statistical Analysis System (SAS). Each surgeon received semiannual reports of 1) overall infection rate by site, 2) number of surgical wound infections by wound class and type of procedure, 3) pathogens for each deep and incisional infection, and 4) quarterly wound infection rates by wound class. Analysis of reports revealed high Class I surgical wound infection rates for both general and orthopedic surgeons. One person in each group had inordinately high infection rates. These data serve as an objective incentive to reduce surgical wound infections, identify individual problems, and suggest surgical privileges be evaluated by performance.

In 1888, Nocard isolated the microorganism responsible for a disease in cattle known as farcy. Eppinger, in 1890, isolated the same pathogen from man. With time, this aerobic gram-positive, partially acid-fast, branching rod became known as Nocardia. Whether Nocardia is a bacterium or fungus was debated for some years. Nocardia has now been classified according to Bergey's system as a bacterium in group 17, order 1: Actinomycetales, family VI: Nocardiaceae.
