TRANSCRIPT
Infection Prevention and Control
Chapter 6
Objectives:
As a result of successfully completing this chapter, students will be able to:
Explain the role of Central Service Technicians in a healthcare facility’s infection prevention and control efforts.
Discuss personal hygiene and personal protective equipment precautions that enable Central Service Technicians to protect patients and themselves.
Define the term, “Standard Precautions,” and review its role in preventing the transmission of infectious organisms.
List key elements in the Bloodborne Pathogens Standard published by Occupational Safety and Health Administration (OSHA).
Objectives:
Describe basic environmental concerns as Central Service work areas are designed.
Review environmental aspects of Central Service work procedures that impact infection control:
Traffic control Work area cleanliness Workflow
Define the terms, “asepsis,” and “aseptic technique,” and review the five basic principles of asepsis.
Infection Prevention and Control Goals of Central
Service
Eliminate and/or destroy all potentially infectious contaminants present on reusable instruments and equipment.
Safely distribute reusable and single-use items required for the delivery of patient care.
Establish and enforce standards for decontamination, disinfection, and sterilization in various healthcare settings.
Medical Devices that have not been properly handled, disinfected or
sterilized…
…can cause infections in patients and staff
Each Year
Approximately 10% of patients hospitalized develop a healthcare facility-associated infection
The primary purpose of the Central Service Department
is to stop the spread of disease-producing
microorganisms in the healthcare facility
Appropriate Attire for Central Service
A facility-issued scrub uniform
Hair covering that covers all head and facial hair except eyebrows and eyelashes
Shoes with non-skid soles
Hand Hygiene
Remove Watches and other Jewelry before entering the work area.
Wash hands with soap and water or use an alcohol-based hand rub
Personal Protective Equipment
Required by OSHA for Technicians in the Decontamination area: General purpose
utility gloves A fluid-resistant
covering with sleeves Full face protection. Shoe covers
Fluid-Resistant Gowns (Coverings)
Regular scrub attire splashed with liquid
Fluid-resistant attire splashed with liquid
Standard Precautions
Place emphasis on the use of blood and body fluid precautions for all patients.
OSHA BloodBorne Pathogen Standard
Written Exposure Control Plan
Training upon initial hire and annually thereafter
Hepatitis B Vaccine offered at no cost to employees
Observance of Standard Precautions
Use of Engineering and Work Practice Controls to reduce risks
OSHA BloodBorne Pathogen Standard
Provision of Personal Protective Equipment (PPE) at no cost to the employee
Provision of a clean and sanitary working environment
Use of appropriate Biohazard signs and labels to identify contaminated items
Rigid containers for sharps disposal
OSHA BloodBorne Pathogen Standard
Covered, puncture-proof containers for the transport of contaminated items.
Provision of medical evaluation and treatment if an employee experiences an exposure
Properly maintained medical and training records.
The Physical Design of the Central Service
Department
Physical Barriers (walls) between clean and dirty areas
A method to reduce the likelihood that airborne bacteria can be transmitted from the decontamination area to the clean areas

Controlling Airflow
Windows and doors between areas with positive and negative air pressures must be kept closed
Work Area Requirements
Decontamination Temperature: 60°F to 65°F (16°C to 18°C)Humidity: 30% to 60%Air Exchanges: 10 per hour
Preparation and PackagingTemperature: 68° F to 73° F (20° C to 23° C)Humidity: 30% to 60% Air Exchanges: 10 per hour
Clean/Sterile StorageTemperature 75° F or lower (24° C or lower)Humidity: Less than 70% Air Exchanges: 4 per hour
Work Area Requirements (cont.)
Hand washing Sinks
Fixtures and furniture that can be washed
Other Requirements:
Open Rack storage systems should have a solid bottom to prevent contamination during housekeeping tasks
Traffic Control
Traffic control requirements must be enforced for everyone
Dress codes for all areas apply to everyone
Traffic Control Designations
Biohazard – OSHA-required PPE
Unrestricted – Normal Traffic areas, cafeteria, waiting rooms, etc. Street clothes may be worn
Semi-Restricted – Clean assembly and storage areas, access corridors to operating rooms, etc. Surgical scrub attire and hair covering required
Restricted – Areas where sterile procedures are performed. Surgical scrub attire, hair covering, and masks required. *Persons working within the sterile field will have additional requirements

Regular Street Attire
Environmental Cleaning
Floors should be wet-mopped at least daily
Work surfaces should be cleaned at least daily
Light fixture should be cleaned at least every 6 months
Walls cabinets and racks should be cleaned on a regularly scheduled basis
Cleaning Sterile Storage Areas
Remove all sterile items from the cart, rack, or cabinet
Thoroughly clean the unit using the cleaning solution recommended by the healthcare facility.
Allow the storage unit to dry thoroughly.
Carefully place items back in their designated location.
Record the cleaning date in the department’s cleaning log.
Control Microorganisms Entering the Work Areas
Clean Routinely
No Food or Drink should be allowed in Central Service work
areas.

Principles of Asepsis
Asepsis – The absence of microorganisms that cause disease
Aseptic Technique – Any activity or procedure that prevents infection or breaks the chain of infection
Medical Asepsis
Procedures performed to reduce the number of microorganisms or minimize their spread
Surgical Asepsis
Procedures performed to eliminate the presence of all microorganisms and/or to prevent the introduction of microorganisms into an area
Principles of Asepsis
1. Know what is Dirty.2. Know what is Clean.3. Know what is Sterile.4. Keep the 3 conditions separate.5. Remedy contamination
immediately.
“Sterile Conscience”
A careless attitude may lead to increased risk of infection
Infection Control...
…manages the growth and transmission of bacteria in the healthcare facility
You Can Manage the Environment by:
Following All Infection Control Protocols
Recognizing Contamination and Correcting the Situation
Paying Close attention to Detail
Controlling the Spread of Microorganisms…
…is the responsibility of every Central
Service Technician
