Staphylococcal infection in subdivided general surgical wards.

Area of Science:

• Infection Control
• Hospital Epidemiology
• Surgical Ward Design

Background:

• Staphylococcus aureus is a common cause of hospital-acquired infections.
• Previous studies have indicated that ward design, such as open versus subdivided wards, can influence the spread of Staph. aureus.
• Understanding the impact of ward layout on bacterial transmission is crucial for patient safety.

Purpose of the Study:

• To investigate the spread of Staphylococcus aureus in general surgical wards with a specific room-based design.
• To compare Staph. aureus nasal carriage and sepsis rates with those observed in previously studied ward types, including open and subdivided wards.
• To evaluate the effectiveness of the studied ward design in mitigating Staph. aureus transmission.

Main Methods:

• A study was conducted in three general surgical wards featuring individual rooms.
• Nasal carrier rates of Staph. aureus in patients were monitored during their hospital stay.
• Staphylococcal sepsis rates were recorded and compared with historical data from different ward environments.

Main Results:

• Patient nasal carrier rates for Staph. aureus increased during ward stays but remained comparable to minimum rates in other subdivided wards and lower than in open wards.
• Staphylococcal sepsis rates were significantly lower than in most open wards.
• Sepsis rates were also considerably lower than in the same unit when it was previously overcrowded and segregated by sex.

Conclusions:

• General surgical wards with separate rooms demonstrate a reduced capacity for Staph. aureus spread compared to open ward designs.
• This ward design may contribute to lower rates of staphylococcal sepsis, enhancing patient safety.
• Optimizing ward infrastructure is a viable strategy for improving infection control in healthcare settings.
