HOSPITAL INFECTION

CONTROL

Cecilia S. Montalban, MD, MScCTM

INFECTION• the state or condition in which the

body or part of the body is invaded by a pathogenic agent (bacteria, virus, parasites etc.) which under favorable conditions multiplies and produces injurious effects

NOSOCOMIAL INFECTION

• latin word “nosocomium” meaning hôspital • synonymous to hospital-acquired infection• infection acquired 48 hours after

admission to hospital (not present or incubating at the time of admission)

• acquired while in the hospital and developed after discharge

Common Sites of Nosocomial Infections

Urinary tract

Respiratory tract

Gastrointestinal

Blood stream

Skin, Wound, Burn

Surgical wound infection

Others

Sources of Agents of Nosocomial InfectionsEXOGENOUS• Hands• Instruments• Catheters• Respiratory

ENDOGENOUS• Oropharynx• Respiratory• Gastrointestinal• Skin

Factors Promoting Endogenous Infections

• Operations

• Catheters

• Foreign bodies

• Chemotherapy

• Immunosuppression

• Pre-existing disease

AGENTAGENT

Means of Transmission of Nosocomial Infections

Contact - direct or indirect

Airborne - measles, varicella, TB

Droplet - meningococcemia

Vector - insects or animals

Vehicle - food, water, blood,

medication

MEANS OF TRANSMISSIONOF NOSOCOMIAL INFECTIONS

CONTACTCONTACTA. Direct ContactA. Direct Contact

- occurs when one person - occurs when one person touches anothertouches another

Factors that Increase Host Susceptibility to Nosocomial Infections

• Chronic underlying diseases• Immune deficiency states

– Malignancies– Therapeutic measures– Immunosuppression– Antibiotic therapy

• Invasive devices• Surgery• Age

Breaking theChain of Infection

• The hands should be washed after handling infectious materials (e.g. bed linen, dressings, secretion and excretions).

• The skin of the patient should be disinfected before invasive procedures

• Emphasize HANDWASHING for personal hygiene

Basic Principles in Infection Control

Rational Use of Devices

- Avoiding or removing factors that impair host defenses.

- Invasive devices should be avoided or should be removed as soon as possible

Isolation Techniques based on method of spread

Protective or Reverse Isolation

Rationale: decreasing the contact of the immunocompromised host to potential pathogens

Immunotherapy, Immunizations and other methods of reconstituting patient’s immune response may be attempted

• The environment should be HOSTILE to the multiplication of pathogens, i.e. clean, dry, exposed to light and well ventilated.

• All infectious materials (e.g. linen, clinical waste, sharps) should be safely contained, decontaminated or destroyed.

• All instruments and equipment should be clean and dry. Invasive items should be sterilized and items in contact with mucous membranes, body fluids and potentially infectious materials should be disinfected.

• Food should be hygienically

prepared, properly cooked and

stored at low temperatures until

• Susceptible patients or sites should be protected from pathogenic microorganisms: i.e. aseptic technique practice during wound dressing, or procedures

• Use of disposable supplies and equipment in an attempt to limit the spread of infection by this means

• Control of insects and rodents that serve as vectors in the spread of microorganisms

AGENTAGENT

The Health Care Worker (HCW) should be aware of how infection is transmitted and the factors involved in the process

The HCW should be able to implement the MOST effective and applicable measures to prevent and control infection in his place of work

The HCW should have the proper attitude of infection control

Objective

To facilitate the effective

prevention,

detection, and

control

of healthcare associated infection among patients, healthcare workers and visitors.

- Personnel Health

- Dietary- Linen & Laundry- Waste Management- Environmental Care

Responsibilities:

Surveillance- nosocomial infection- antimicrobial resistance- proper infection control practice- personnel health- outbreaks- environment

Training and education of healthcare staff

An effective ICT:• Maintains direct access to a representative of the Hospital

Director/Administrator• Responsible to the ICC• Functions on a daily basis• Has access to appropriate facilities to enable it to perform

its duties• Have an efficient mechanism of reporting significant

hospital outbreaks

Responsibilities• Educates, trains, and advises staff on all aspects

of infection control

• Conducts surveillance activities:• Nosocomial infections• Antibiotic resistance• Infection control practices

Establishing An Establishing An Infection Control ProgramInfection Control Program

• Identify interested and key hospital personnel as members of the ICC/ICT

• Accomplish a written description of the program (Infection Control Plan)• Goals, objectives, structure• Specific surveillance, prevention, control,

education, and training activities

• Formulate written policies and procedures• study existing practices• modify existing policies as needed

• consider difficulties during implementation• after hospital-wide consultation• Implement changes gradually• Have the cooperation of the staff

• Formulate written policies and procedures• simple, easy to follow, common sense• consider costs and availability of supplies• maintain standard of care• incorporate written policies in the IC manual• Monitor and evaluate periodically

• Disseminate information • Implement and monitor• Annual evaluation on the IC program

• Assess the activities• Assess accomplishments • Identify any changes in goals, objectives,

structure• Assess the value of the program to the hospital

INFECTION CONTROL is…

Infection Control should be

..... a WAY of LIFE!
