Nosocomial infection in pediatric surgical patients: A study of 608 infants and children

We studied nosocomial infection in a group of 608 pediatric surgical patients over a 14-month period. All inpatients and outpatients who received an operation with an incision by the pediatric general surgical service were entered into the study. Demographic, nutritional, clinical and laboratory data were collected. Surveillance was conducted for wound infection, septicemia, infections of the respiratory tract, urinary tract, and abdomen, and infectious diarrhea. A total of 676 operative procedures was performed. Nosocomial infection occurred in 38 of the 608 patients (6.2%). A total of 53 infectious complications was tabulated. The number and percent risk per operation were wound 17 (2.5%), septicemia 14 (2.1%), pulmonary 10 (1.5%), urinary tract 5 (0.7%), abdominal 5 (0.7%), diarrhea 2 (0.3%). Broviac catheter sepsis occured in 7 of 61 lines (11.5%). The highest overall occurence of infection was in the infant group (1 mo to 1 yr), ( 13 161 , 8.1%). The probability of septicemia was highest in neonates (4.2%) compared with infants (3.1%) or older children (1.2%) ( P < .05). The most common isolates were Staphylococcus epidermidis ( 10 17 ) from septic patients, and gram-negative enteric bacteria ( 27 50 ) from organ and wound infections. Infection was associated with impaired nutrition, multiple disease processes, and multiple operations. The risk of nosocomial infection in this population was comparable to that reported in adult surgical patients. These baseline data may aid the development of strategies to lower infection risk in children.
