Course Introduction
New York State Department of Health and State Education Department
Background
In August 1992, Chapter 786 of the Laws of 1992 established a requirement that certain
health care professionals licensed in New York State receive training on infection control and
barrier precautions by July 1994, and every four years thereafter, unless otherwise exempted.
This statute affects every dental hygienist, dentist, licensed practical nurse, optometrist,
physician, physician assistant, podiatrist, registered professional nurse, and specialist assistant
practicing in New York State. The rationale for this requirement has its origins in several events
over the past two years.
One of the most important of these was the Department of Health's establishment of a
policy on health-care workers infected with human immunodeficiency virus (HIV) or hepatitis B
virus (HBV). Another important event was the adoption by the Board of Regents, effective
March 1992, of an amendment to Regents Rules expanding the definition of unprofessional
conduct to include failure to follow appropriate infection prevention techniques in health care
practice. The Department of Health has adopted similar regulations.
The question of how to protect patients from contracting HIV through receipt of health
care has been the subject of debate in the scientific community as well as in public and private
sectors. The Department of Health has been intensely involved in this issue at both the state and
national levels. As a result of these deliberations, consensus has been reached in New York State
that the strategy that offers the greatest opportunity for protecting the public in settings
where they receive health care is one of assuring that infection control measures are
routinely in place and routinely observed. Such practices must provide protection from cross
contamination from patient to patient, as well as patient and health-care worker exposure to
pathogens through the direct provision of care. While blood borne pathogens are the chief
concern driving policy and legislation at this time, other pathogens transmitted by contact spread
(e.g., staphylococci, gram-negative organisms) also may pose a risk. Broad attention to the
principles of infection control will diminish the opportunity for these exposures as well.
For many years, regulated health care settings, such as hospitals, nursing homes, and
diagnostic and treatment centers have been required to have in place infection control programs
designed to protect patients, employees, and visitors. Established policies and procedures address
a number of concerns including hand washing, prevention of infection associated with surgery,
IV delivery, the use of urinary catheters and other invasive procedures, housekeeping,
disinfection and sterilization of equipment, waste disposal, and other areas that may be a source
of infection. Isolation and employee health policies also limit the potential for exposure to
communicable diseases and provide a mechanism for follow-up when inadvertent exposures
occur. Through surveillance of infection in these settings, and quality assurance and risk
management programs, compliance with infection control standards are monitored and problems
identified early. Attention to the infection control program has had an important impact on
reducing nosocomial and occupationally acquired infections.
Goal of Infection Control Training as Mandated by Chapter 786
The goal of the recently established infection control training requirement is to assure
that licensed, registered, or certified health professionals understand how blood borne pathogens
may be transmitted in the work environment and recognize their professional responsibility for
assuring that they, and those for whom they are responsible, apply scientifically accepted
infection control principles, as appropriate to their work setting, to minimize the opportunity for
transmission to patients and employees. In addition, the training should establish that failure to
adhere to such standards can be considered evidence of professional misconduct and could lead
to disciplinary action.
MINIMUM CORE ELEMENTS OF REQUIRED COURSE WORK OR TRAINING IN
INFECTION CONTROL
Element I: The responsibility to adhere to scientifically accepted principles and practices of
infection control and to monitor the performance of those for whom the professional is
responsible.
Element II: Modes and mechanisms of transmission of pathogenic organisms in the health-care
setting and strategies for prevention and control.
Element III: Use of engineering and work practice controls to reduce the opportunity for patient
and health-care worker exposure to potentially infectious material.
Element IV: Selection and use of barriers and/or personal protective equipment for preventing
patient and health-care worker contact with potentially infectious material.
Element V: Creation and maintenance of a safe environment for patient care through application
of infection control principles and practices for cleaning, disinfection, and sterilization.
Element VI: Prevention and control of infectious and communicable diseases in health-care
workers.
ELEMENT I - PROFESSIONAL RESPONSIBILITY
The responsibility to adhere to scientifically accepted principles and practices of infection
control and to monitor the performance of those for whom the professional is responsible
DEFINITIONS
Unprofessional Conduct - The failure to use scientifically accepted infection prevention
techniques for the cleaning, disinfection and/or sterilization of instruments, devices, materials,
and work surfaces; utilization of protective garb; use of covers for contamination prone
equipment, and the handling of sharp instruments.
HCW - Health Care Worker
Introduction
Mandatory Infection Control Training for Health Care Personnel
The New York State Education Department and Department of Health are actively promoting
infection control training to prevent blood borne disease exposure to both health care workers
and their patients. Recent regulations require hospitals to train their staff, provide appropriate
equipment, and enforce the use of universal barrier precautions in situations involving potential
exposure to blood and body fluids. In addition, the state requires licensed health care
professionals, including registered nurses, to complete infection control training and barrier
precautions course every four years. (A waiver of this training requirement may be granted by
the Department of Health to health professionals who demonstrate that such training is not
needed due to the nature of their work, or that they have met criteria for equivalency.)
Enforcement of Infection Control Standards
Hospitals and other licensed health care facilities are responsible for monitoring and enforcing
infection control practices by HCW under their jurisdiction. Failure to do so can result in
citations, fines, and other disciplinary action. Likewise, any licensed health care professional
who fails to use proper infection control techniques to protect patients can be subject to
disciplinary action and charges of professional misconduct. HCWs must also ensure that those
under his or her supervision use appropriate infection control techniques as well.
Complaints by patients or employees of lax infection control practices will result in Department
of Health or Education investigations. If the charges are substantiated, it may result in charges of
misconduct for any licensed worker who was directly involved, who knew about the violation, or
who is responsible for supervising an inadequately trained staff.
I. SOURCE OF REGULATIONS, STANDARDS, AND SCOPE OF AUTHORITY FOR
INFECTION CONTROL STANDARDS FOR PROFESSIONAL CONDUCT
A. Federal Regulations
1. The Occupational Safety and Health Administration (OSHA) issued mandatory
regulations requiring employees to provide a safe and healthful workplace. Recent
regulations: Blood borne Pathogen Standards and tuberculosis enforcement policy
and procedures.
2. Centers for Disease Control and Prevention (CDC) issued guidelines and
recommendations concerning infection control standards such as “Universal
Precautions”.
B. Rules of the Board of Regents, Section 29.2(a)(13)
1. Establishes the failure to adhere to accepted infection control techniques as
unprofessional conduct under the law. This regulation specifies several techniques
for infection prevention and requires licensed health care professionals to understand
the methods of cleaning and sterilization, utilization of protective clothing, and
handling of sharp instruments. Please be sure to read the text of the rules.
C. Part 92 of Title 10 Health Regulations
Laws of New York Chapter 786
1. The Department of Health issued these regulations to protect HIV or HVB infected
HCWs from discrimination in employment and in their professional practice and to
secure the public safety. The DOH evaluated the risks and potential for exposure, and
concluded the following. Click here for the text.
2. The New York State Public Employees Safety and Health Act (PESH) is responsible
for the protection of public employees at the workplace.
3. Chapter 786 of the Laws of New York State 1992 includes provisions to protect
citizens from exposure to HIV, HBV, and other pathogens during medical and dental
procedures. This law identified the failure to comply with the implementation of
infection control prevention strategies as grounds for charges of unprofessional
conduct.

ELEMENT II - TRANSMISSION AND PREVENTION
MODES AND MECHANISMS OF TRANSMISSION OF PATHOGENIC ORGANISMS
IN THE HEALTH CARE SETTING AND STRATEGIES FOR PREVENTION AND
CONTROL
DEFINITIONS
Infection: Replication of organisms in tissues of a host, with a development of an overt clinical
manifestation - disease.
Pathogen or Infectious Agent: A biological agent capable of causing disease.
Portal of exit/entry: Path by which a pathogen leaves the reservoir and enters the host.
Reservoir: Any person, animal, arthropod, plant, soil or substance (or combination of these) in
which an infectious agent normally lives and multiplies, on which it depends primarily for
survival, and where it reproduces itself in such a manner that it can be transmitted to a
susceptible host.
Susceptible Host: A person or animal lacking effective resistance to a particular infectious
agent.
Common vehicle: Contaminated material, product, or substance that serves as an intermediate
means by which an infectious agent is transported to two or more susceptible hosts.
Transmission: Any mechanism by which a pathogen is spread by a source or reservoir to a
person.
I. OVERVIEW OF TRANSMISSION OF PATHOGENIC ORGANISMS
A. Concept of "The Chain of Infection"
Three elements of infection: pathogen, mode of transmission, and susceptible host.
1. Presence of a pathogen, or infectious agent, is required for infection.
(Pathogens found in patient, HCWs, environment, etc.)
a. Bacteria: single celled microorganisms (TB, MRSA, streptococcus, E. Coli,
pseudomonas, C. difficile)
b. Viruses: sub microscopic elements that require a host to grow, similar to a seed
(herpes, influenza, HIV, HBV, HBC, varicella voster)
c. Fungi: molds or yeasts that live on plants and animals (candida, aspergilla,
cryptococcus)
d. Parasites: (protozoa, tapeworm, lice, ticks)
2. Role and nature of "reservoirs" - habitat for the pathogen
a. Animate: living being (people or animals)
b. Inanimate: objects or things which are not living (tourniquet or bathtub)
c. Acute v. Carrier State:
The acute phase is a state of illness where the infection is apparent. Carrier
state means the virus is present with no apparent signs of disease. A carrier
can continue to transmit after acute infection/disease is over. An intermittent
transmitter can not transmit the organism continuously, but intermittently.
3. Portals of exit: vehicles and mechanisms by which pathogens leave the body.
a. coughing, sneezing respiratory/oral secretions
b. draining lesions
c. diarrhea
d. drainage of blood and other body substances
4. Modes by which pathogens are transmitted to a susceptible host.
a. Contact
1) Direct: person to person touch
2) Indirect: contact with an inanimate object carrying the pathogen
3) Droplet: passage through the air attached to a large respiratory droplet from a
cough or sneeze
b. Airborne
Passage of an infectious agent through the air. The size and density of the air
particles determines how far the pathogen can travel.
c. Common vehicle
The pathogen contaminates a vehicle such as shared food and is spread to
many susceptible hosts.
d. Vectorborne
The pathogen is carried to a host through insects.
5. Portals of entry: sites and mechanisms by which pathogens are introduced
a. Entry sites - site where the microorganism is introduced to the host (mucous
membranes, non-intact skin, gastrointestinal, respiratory, genitourinary tracts,
placenta)
b. Mechanical introduction - ways in which the pathogen is introduced to the host
(percutaneous injury, vascular access and other invasive devises, surgical incision,
permucosal contact)
B. Factors which influence the outcome of an exposure
1. Impairment of host defenses, e.g., age, prematurity, chronic disease, as mediated by
changes in:
a. natural barriers, e.g.,
1) Intact skin
first line of defense against pathogens
2) Respiratory cilia
remove organisms that invade the respiratory tract
3) Gastric acid
helps to kill bacteria
4) Tears
wash contaminants away from eyes
b. Immune system, e.g.,
1) Inflammatory response, e.g., neutrophils
2) Humoral immunity, e.g., antibodies
3) Cell-mediated immunity, e.g., macrophages, T-lymphocytes
2. Virulence of the pathogenic organism
Potency or strength of the pathogen; its power to cause infection (the more
virulent the organism, the easier it will be to cause infection).
3. Size of inoculum - the larger the size, the greater the exposure.
4. Route of exposure - certain portals of entry are more effective than others at causing
disease.
5. Duration of exposure - the longer the exposure, the greater the risk of becoming
infected.
II. CONCEPTS OF PREVENTION (BREAKING “THE CHAIN OF TRANSMISSION”)
A. Recognition and control of reservoirs
1. Recognition:
a. Observing for signs and symptoms of disease such as fever, swelling, or redness.
b. Laboratory, radiological, and other diagnostic testing or procedures.
2. Control:
a. Antimicrobial therapy (antibiotics)
b. Eliminating or controlling inanimate environments that support the growth of
pathogenic organisms.
B. Control of routes of transmission
1. Hand washing - ESSENTIAL
2. Use of barriers - gloves, masks, goggles, etc.
3. Sterilization or disinfection of patient care equipment
4. Isolation/cohorting communicable individuals (consider all patients as potentially
infectious and use universal precautions at all times; implement other precautions as
necessary)
5. Environmental practices
a. Housekeeping
b. Ventilation - adequate exchange patterns.
c. Waste management
d. Linen and laundry management
C. Support and protection of the host
1. Vaccination (influenza, hepatitis B, MMR, pneumococcal, DPT, HIB, Polio)
2. Pre- and post-exposure prophylaxis
3. Protecting skin and immune system integrity
III. APPLICATION OF CERTAIN PREVENTION CONCEPTS
A. Hand washing
Consistent hand washing is the single most effective way to guard against
infection—simple, inexpensive, and highly effective.
Unfortunately there is a low level of compliance in many settings.
i.
People aren't aware of the importance
ii.
Not emphasized as a priority
iii.
HCWs don’t see themselves at risk.
iv.
Can be inconvenient because of lack of sinks or towels
v.
Soaps and scrubs can irritate skin
vi.
Not part of the hospital culture—other's don't do it
1. Selection of hand washing agents based on need for safe patient care:
b. In non-patient care areas, plain soap is sufficient. It removes transient flora but
does not kill microorganisms.
c. In high-risk and patient care areas, antiseptic or antimicrobial agents should be
used to reduce colonizing flora.
2. Factors which influence hand washing efficacy
a. mechanical friction: removes large amounts of visible contamination
b. warm running water: rinses away loosened debris and pathogens
c. Soap: removes matter by disolving oils that contain pathogens
3. Sources of potential contamination or cross-contamination of and washing materials.
a. Bars of soap might sit in pools of stagnating water that can hold and spread
pathogens. It is recommended to dispose of used soap bars frequently.
b. Refillable soap dispensers should not be filled before they are emptied and
cleaned. Topping off at low levels can allow pathogens to fester.
c. Disposable, non-refillable soap dispenser pumps are the best option.
To increase efficiency when hand washing:
1) Designated hand-washing sinks should be located close to patient care areas.
2) Foot pedals make sinks easier to use and reduce the risk of crosscontamination.
3) Even if you are wearing gloves, be sure to wash your hands before and after
any patient contact.
4) Always wash after touching contaminated materials.
5) Use waterless soaps when water is unavailable, but be sure to wash with water
as soon as you can.
B. Precaution/isolation strategies
1. Interaction-driven approaches
Considers contact with blood and body fluids without regard to diagnosis.
a. Rationale for interaction-driven strategies: infections can be present without a
diagnosis or knowledge of the health care provider.
b. Types of systems
1) Universal Precautions (UP) - treats all blood and body fluids as potentially
infectious. (blood, amniotic fluids, pericardial, peritoneal, synovial and
cerebrospinal, semen, vaginal secretions)
2) Body Substance Isolation (BSI) - precautions with all body fluids. (includes
all UP fluids plus urine, feces, sputnum, saliva, and wound drainage)
3) Segregating individuals with similar symptoms
2. Diagnosis-driven approaches
a. Types of systems
1) Isolation by disease or category, based either on mode of transmission or
etiology.
2) Cohort individuals infected with same pathogen to the same room.
3) Transfer or discharge infected individuals if your hospital is unable to provide
adequate isolation strategies.
b. Application in specific health care settings
1) You must be aware of your Hospital's specific policies and procedures relating
to infection control.
2) The infection control department is available for questions and help.
ELEMENT III - REDUCING EXPOSURE
USE OF ENGINEERING AND WORK PRACTICE CONTROLS TO REDUCE THE
OPPORTUNITY FOR PATIENT AND HEALTH CARE WORKER EXPOSURE TO
POTENTIALLY INFECTIOUS MATERIAL.
DEFINITIONS
Engineering Controls: equipment, devices, or instruments that remove or isolate a hazard.
Work Practice Controls: controls that reduce or eliminate the likelihood of exposure by
altering the manner in which a task is performed
I. HIERARCHY OF CONTROLS TO PREVENT EXPOSURE OF PATIENTS AND
HEALTH CARE WORKERS (HCW) TO POTENTIALLY INFECTIOUS
MATERIALS
A. Engineering controls
Equipment or instruments that remove or isolate health care professionals and
patients from pathogens. Examples include puncture resistant sharps disposal
containers, needleless systems, and air exchange ventilation systems.
B. Work practice controls
Habits or methods by which tasks are performed that reduce or eliminate the
likelihood of exposure. Examples include hand washing and respiratory protection.
C. Personal Protective Equipment (PPE)
Protection to supplement engineering and work practice controls if risk still exists.
Includes gloves, masks, gowns, and eye wear. Discussed further in Element IV.
II. APPLICATION OF A HIERARCHY CONCEPT TO BLOODBORNE PATHOGENS
AND CONTACT EXPOSURE
A. Circumstances and practices which increase opportunities for exposure
1. Percutaneous exposures
A piercing of the skin barrier, causing a point of entry for blood or other infectious
material
a. Injury through handling, disassembly, disposal, or reprocessing of needles and
other sharps (manipulating needles and other sharps by hand, recapping using a
two-handed technique, removing scalpel blades).
b. Procedures in which there is opportunity for injury, particularly where there is
poor visualization which can expose the patient as well as the HCW:
1) blind suturing
2) non-dominant hand opposing or next to a sharp
3) bone spicules, metal fragments
2. Mucous membrane/non-intact skin exposures
a. Direct contact with blood or body fluid
b. Splashes or sprays of blood or body fluid
3. Parenteral exposures
a. Injection with infectious material.
b. Infusion of contaminated blood products.
c. Transplantation of contaminated organs/tissues.
B. Identification of those at risk for exposure
1. Direct provider
2. Assistants
3. Ancillary personnel
4. Patients
C. Engineering controls which eliminate or isolate the hazard
1. Safer devices for needlestick prevention
a. Strategies for preventing needlestick injuries
1) Eliminate the needle or sharp.
2) Provide continuous protection of the needle or sharp.
3) Provide a mechanism to safely cover the sharp immediately after use.
b. Important concepts
1) Passive vs. active safety features
i.
passive - the safety feature is activated automatically
ii.
active - the safety device must be activated by the HCW
2) Integrated safety equipment vs. accessory
i.
integrated - safety device is part of the equipment
ii.
accessory - requires additional devices
Examples:
3) Needleless needles
4) Self sheathing needles
5) Blunt suture needles
6) Mechanical pipette
2. Puncture-resistant containers for the disposal and transport of needles and other
sharps.
3. Splatter shields on medical equipment, such as locking centrifuge lids.
D. Work practice controls
1. Avoiding unnecessary use of needles and other sharps.
2. Using care in the handling and disposal of needles and other sharp devices:
a. Either not recapping or, when necessary, using an appropriate one-handed
technique
b. Passing sharp instruments by use of designated "safe zones"
c. Disassembling sharp equipment by use of forceps or other device
d. Conveniently located and frequently emptied sharps disposal containers
3. Modifying procedures to avoid injury, e.g.,
a. Using forceps, suture holder, or other instruments for suturing
b. Not holding tissue with fingers
c. Not leaving sharps on a field
4. Hand washing
5. Prompt cleaning of blood and body fluid spills
6. Worker training education and monitoring of others to aid them in compliance
III. APPLICATION OF A HIERARCHY CONCEPT TO AIRBORNE PATHOGENS
Exposure to airborne pathogens occurs just by being present - contact is not necessary.
A. Circumstances which increase opportunities for exposure
1. Inadequate ventilation
2. Lack of source control
