Nosocomial gastroenteritis in paediatric patients

Area of Science:

• Pediatrics
• Infectious Diseases
• Hospital Epidemiology

Background:

• Acute gastroenteritis is common in children under 5 years.
• Identifying causative agents is crucial for effective treatment and prevention.
• Nosocomial infections pose a significant challenge in healthcare settings.

Purpose of the Study:

• To investigate the incidence and causative agents of acute gastroenteritis in a pediatric isolation ward.
• To determine the rate and common pathogens responsible for nosocomial infections.
• To evaluate the effectiveness of existing isolation procedures in preventing rotavirus transmission.

Main Methods:

• Retrospective analysis of 2228 children under 5 admitted with acute gastroenteritis between November 1982 and April 1985.
• Identification of causative agents including rotavirus and common bacteria (Salmonella, Campylobacter, Shigella, Escherichia coli).
• Review of isolation procedures: cohort nursing, barrier gowns, and chlorhexidine handwashing.

Main Results:

• Rotavirus was identified in 56.2% of cases.
• 13.4% of positive cases were nosocomial infections.
• Rotavirus accounted for 128 nosocomial infections (20% of all rotavirus cases), significantly more than bacterial pathogens (35 cases, 7%).
• Nosocomial rotavirus gastroenteritis was 3.4 times more frequent than bacterial nosocomial gastroenteritis.

Conclusions:

• Current isolation procedures are insufficient to prevent rotavirus nosocomial infections.
• Rotavirus gastroenteritis represents a substantial nosocomial risk in pediatric settings.
• Modifications to isolation protocols are necessary to reduce rotavirus transmission.
