Hospital Infection Control

Infection control is an essential requirement in healthcare delivery. It involves not only the cleaning, disinfection and sterilization of medical equipment, but also environmental hygiene, laundry management, appropriate facilities, equipment, trained personnel and professional education.

The following article outlines several basic conditions that support infection control in healthcare facilities. The content has been edited and summarized based on the requirements referenced in Circular No. 18/2009/TT-BYT of the Ministry of Health regarding the organization of infection control activities.

Hospital infection control

1. Facilities for Infection Control

Healthcare facilities should be designed and equipped to support infection control requirements. Infection control considerations should be incorporated when healthcare facilities are newly constructed, renovated or upgraded.

Important areas may include:

Central disinfection and sterilization areas;
Laundry and linen processing areas;
Waste storage and treatment areas;
Isolation rooms for patients with a risk of transmitting infectious agents;
Procedure rooms and critical care areas;
Appropriate water supply, drainage and sanitation systems.

The arrangement of these areas should help reduce the risk of cross-contamination between clean areas and areas with a higher risk of contamination. In specialized departments such as sterilization units and hospital laundries, a well-organized workflow is particularly important.

2. Central Disinfection and Sterilization Areas

Central disinfection and sterilization areas should be organized to support the safe processing of reusable medical devices. Areas used for handling contaminated instruments, cleaning, sterilization and storage should be clearly arranged according to their functions.

Depending on the size and operational requirements of the healthcare facility, equipment may include:

Washer-disinfectors;
Steam sterilizers;
Low-temperature sterilization equipment;
Drying equipment;
Packing and storage equipment;
Cleaning and disinfection chemicals and sterilization quality control tools.

A properly organized processing area can help reduce the risk of contamination throughout the cleaning, disinfection, sterilization and storage process.

3. Hospital Laundry and Medical Linen Management

The laundry department is an important part of a hospital's infection control system. Linen used during patient care may be contaminated with microorganisms, blood or body fluids and therefore requires appropriate collection, transportation and processing.

Hospital laundry facilities may require equipment and resources such as:

Industrial washing and extraction equipment;
Laundry drying equipment;
Ironing or finishing equipment;
Transportation carts for soiled and clean linen;
Containers and facilities for handling contaminated linen;
Storage areas for linen before and after processing;
Appropriate laundry and disinfection chemicals.

One important principle is to reduce the risk of cross-contamination during linen handling. Soiled linen should be collected and transported appropriately, while clean linen should be protected from possible recontamination during storage and distribution.

4. Environmental Hygiene and Waste Management

Infection control should not be limited to treatment areas. Environmental hygiene is an important part of infection prevention throughout the healthcare facility.

Healthcare facilities should provide appropriate cleaning equipment, hand hygiene facilities, suitable cleaning and disinfection chemicals, as well as systems for the collection, transportation and storage of waste.

Areas with a higher risk of contamination require particular attention. Environmental cleaning should be organized according to appropriate procedures to help reduce the spread of infectious agents during healthcare activities.

Medical waste should also be collected, segregated, transported and treated appropriately in order to reduce risks to patients, healthcare workers and the surrounding environment.

5. Required Equipment and Resources

Healthcare facilities require appropriate equipment and resources to support infection control activities and environmental hygiene.

Basic resources may include:

Hand hygiene facilities;
Cleaning and disinfection chemicals;
Personal protective equipment;
Environmental cleaning tools and equipment;
Waste collection and storage equipment;
Tools for quality monitoring and evaluation.

Providing equipment alone is not sufficient. Equipment and supplies must also be used correctly, according to appropriate procedures, and checked regularly to maintain their effectiveness.

6. Infection Control Personnel

Infection control activities require appropriately trained and assigned personnel. In addition to departments directly involved in sterilization, laundry and environmental hygiene, healthcare facilities also need personnel responsible for monitoring and supporting infection control activities.

Dedicated personnel play an important role in developing procedures, providing professional guidance, monitoring implementation and identifying potential risks that may affect the safety of patients and healthcare workers.

7. Education and Professional Training

Training is essential to ensure that infection control measures are properly applied in daily practice. Healthcare workers and personnel who may be exposed to infectious materials should receive appropriate guidance on professional procedures, hand hygiene, personal protective equipment and relevant preventive measures.

Continuous education and knowledge updates can help personnel better understand infection risks and improve compliance with infection control procedures.

8. Monitoring and Continuous Implementation

Infection control is an ongoing process. In addition to providing facilities and equipment, practical procedures should be monitored and evaluated during implementation.

Inspection, monitoring and evaluation can help healthcare facilities identify areas that require improvement and take appropriate action to maintain effective infection control practices.

Conclusion

Hospital infection control is a comprehensive system involving facilities, equipment, environmental hygiene, laundry operations, personnel, education and monitoring.

Proper coordination of these elements can help reduce the risk of infection, protect patients and healthcare workers, and support the overall quality and safety of healthcare services.
