SECTION 15.75 (A) TUBERCULOSIS EXPOSURE CONTROL POLICY
Last Update: 11/03
GENERAL POLICY STATEMENT
The
State of Iowa ensures a safe workplace environment for all employees, service
recipients, and the public. To that
end, the Department of Administrative Services – Human Resources Enterprise has
established this policy addressing the spread of tuberculosis within the
workplace and the responsibility of each state department to implement this
policy.
Tuberculosis
is a serious and recognized hazard. Feasible
and useful abatement methods exist. The
purpose of the “Tuberculosis Exposure Control Policy” is to provide minimum
standards for departments to follow in developing and implementing their own
tuberculosis abatement and control standards.
This Tuberculosis Exposure Control Policy is based on guidance from:
·
Occupational Safety and Health Administration’s
(OSHA) “Enforcement Policy and Procedures for Occupational Exposure to
Tuberculosis.”
·
Centers for Disease Control and Prevention’s (CDC)
“Morbidity and Mortality Weekly Reports,” guidelines and recommendations.
·
Iowa Occupational Safety and Health’s policies and
procedures.
This
Tuberculosis Exposure Control Policy is intended to supplement the efforts of
departments and not to replace the tuberculosis control policies and abatement
measures they currently implement.
NONDISCRIMINATION STATEMENT: It is illegal under the Americans With
Disabilities Act to refuse to hire, accept, register, classify, or refer for
employment, or to otherwise discriminate in employment against an applicant for
employment or an employee because the individual has been exposed to
tuberculosis. The burden shall be on
the department to demonstrate, when taking an adverse action against an
applicant or an employee, that the contagious disease is present, poses a
direct threat to health or safety, and that no reasonable accommodation could
reduce or eliminate this threat.
OCCUPATIONAL TUBERCULOSIS
EXPOSURE CONTROL PROGRAM
I.
Scope and Application
A. The
following departments and employees shall be covered by this policy:
1. Departments
with the following workplaces, as identified by OSHA “Enforcement Policy and
Procedures for Occupational Exposure to Tuberculosis,” which have a high risk
of tuberculosis exposure:
a. Hospitals
and other health care settings.
b. Departments
other than hospitals whose employees routinely work in hospitals.
c. Employers
who deliver non-emergency health care to patients in settings other than
hospitals or clinics.
d. Correctional
institutions.
e. Homeless
shelters.
f.
Long-term care facilities.
g. Drug
or alcohol treatment or counseling facilities.
h. Employers
of emergency personnel.
2. Employees
who are assigned to workplaces which place them in significant contact with the
following groups and pose a potential risk for tuberculosis exposure:
a. Persons
known or suspected to have tuberculosis, sharing the same household or other
enclosed environments.
b. Persons
infected with human immunodeficiency virus (HIV).
c. Persons
with medical risk factors known to increase the risk of disease if exposure has
occurred.
d. Foreign-born
persons from countries with high tuberculosis prevalence.
e. Medically
underserved low-income populations, including high risk racial or ethnic
minority populations.
f.
Alcoholics and intravenous drug users.
3. Emergency
personnel and employees who are assigned as inspectors, consultants,
investigators, or in similar positions to workplaces identified as having a
high risk of tuberculosis exposure.
B. Any
contractor that is required to perform work within an area with increased risk
of tuberculosis must receive training prior to admittance or have a documented
Tuberculosis Exposure Control Program prior to initiating any work that brings
the contractor or contractor representatives within an area with increased risk
of tuberculosis.
C. Nothing
in this policy shall be construed as limiting the obligation of any state
department to address the hazard of tuberculosis when the department acquires
information indicating that employees are, or have been, occupationally exposed
to a tuberculosis hazard in the workplace.
For tuberculosis exposure to be compensable under Workers’ Compensation,
the following criteria must be met:
1. The
exposure to the disease must be the result of a higher than normal general
population risk that occurred in the course of employment.
2. Actual
onset of disease must be present. The
onset of disease will be determined by a qualified health care professional.
3. Diagnostic
testing for medical monitoring or screening purposes will not generally be
covered until the onset of the disease is confirmed. In the case of tuberculosis, the Mantoux PPD (purified protein
derivative) test is a screening and monitoring test only.
D. The
policies and procedures for tuberculosis exposure control will be reviewed at
least annually (more frequently with changes in operations) and evaluated for
effectiveness to determine the actions necessary to minimize the risk of
tuberculosis transmission. This review
process shall include:
1. Risk
assessment evaluation.
2. Periodic
reassessment.
3. Case
surveillance.
4. Analysis
of testing procedures.
5. Observation
of employee exposure control practices.
6. Monitoring
engineering control practices.
II. Tuberculosis
Exposure Control Program
An effective tuberculosis infection/exposure control program requires early detection, isolation, and treatment of persons with active and infectious tuberculosis. The primary emphasis of the Tuberculosis Exposure Control Plan will be to achieve these goals through the use of the following program control measures:

and Periodic Risk Assessment
1. Evaluate
the Mantoux PPD (purified protein derivative) test conversion data for
employees identified as employed in workplaces or population groups considered
at risk, by area.
2. Determine
tuberculosis incidence and prevalence among service populations.
3. Analyze
employee and service populations’ test data, by area.
B. Written
Tuberculosis Exposure Control Program
1. Document
all aspects of tuberculosis control.
2. Identify
individual responsible for tuberculosis control program; e.g., a site specific
Tuberculosis Exposure Control Coordinator.
3. Explain
and emphasize hierarchy of controls:
a. Engineering
controls

for tuberculosis infection among persons at increased risk of tuberculosis or
for whom the consequences of tuberculosis may be especially severe to identify
those for whom preventive treatment is indicated.
2. Establish
the following abatement methods:
a. Pre-placement
evaluation.
b. Administration
and interpretation of tuberculosis Mantoux skin tests by a licensed health care
professional and at no cost to the employee:
(1) For
employees with a potential for occupational exposure to protect both the staff
and the State’s service recipients.
(2) At the
time of employment for all employees in the covered workplaces, unless there is
a previous positive test or documented completion of adequate preventive
therapy.
(3) Annually
for all employees assigned to workplaces identified as having a high risk of
tuberculosis exposure in the covered workplaces.
(4) Retested
every six months for workers with frequent exposure to patients with
tuberculosis or who are involved with high hazard procedures.
E. Evaluation
and Management of Possible Infectious Tuberculosis
1. Establish
criteria the covered department will use to determine whether a persons is a
suspected infectious tuberculosis case.
a. Provide,
as soon as reasonably possible after discovery of a suspect infectious
tuberculosis case, medical evaluation for tuberculosis and, where medically
appropriate, preventive therapy to any employee or institutional resident.
2. Establish
procedures to ensure immediate identification of source cases and to ensure,
while maintaining appropriate confidentiality, that all source cases known to
the department are identified to employees who need this information in order
to take proper precautions against tuberculosis exposure.
3. Evaluate
Mantoux PPD (purified protein derivative) test conversions and possible
nosocomial tuberculosis transmission (see attached Flow Chart).

III. Definitions.
“Direct threat” means that there is:
·
A significant risk of substantial harm.
·
An identified specific risk.
·
A current risk, not one that is speculative or
remote.
·
An assessment of risk based on objective medical or
other factual evidence regarding a particular individual.
Even
if a genuine significant risk of substantial harm exists, the department must
consider whether the risk can be eliminated or reduced below the level of a
“direct threat” by reasonable accommodation.
Any
determination of a direct threat to health or safety must be based on an
individualized assessment of objective and specific evidence about a particular
individual’s present ability to perform essential job functions, not on general
assumptions or speculations about a disability.
“Emergency personnel” means
any person employed by or under the supervision and control of any of the
employers specified among affected departments.
“Employee” means any person employed by
or under the supervision and control of any of the employers specified under
“Covered Employers.”
“High Efficiency Particulate filter (HEPA)” means
99.97 percent efficient against 0.3 micrometer monodisperse particles.
“High hazard procedure” means
(1) aerosolized pentamidine
administration and sputum induction; or (2) a procedure performed on a
suspected or confirmed infectious tuberculosis case which can aerosolize body
fluids likely to be contaminated with tuberculosis bacteria including, but not
limited to: (a) operative procedures such as tracheotomy, thoracotomy, or lung
biopsy; (b) respiratory care procedures such as tracheostomy or endotracheal
tube care; (c) diagnostic procedures such as bronchoscopy and pulmonary
function testing; or (d) resuscitative procedures performed by emergency personnel;
or (3) autopsy, laboratory, research, or production procedures performed on
tissues known or suspected to be infected with tuberculosis which can
aerosolize tuberculosis-contaminated fluids.
“HIV” means the human
immunodeficiency virus, symptomatic of Acquired Immunodeficiency Syndrome
(AIDS).
“Isolation room” means an enclosed
space which is used to provide atmospheric isolation in accordance with
“Tuberculosis Exposure Control Plan.”
“Local exhaust ventilation” means
ventilation provided by a device, e.g., an enclosed or semi-enclosed exhaust
hood, booth, or tent, which removes airborne contaminants at or near their
source.
“Nosocomial infection” means
an infection acquired in a hospital.
“Patient” means a person present for
the purpose of medical evaluation or treatment.
“Reasonable accommodation” requires
an employer to make a change in the work environment or in the way things are
usually done to accommodate the known physical or mental limitations of a
qualified applicant or employee with a disability unless it can show that the
accommodation would cause an undue hardship on the operation of its
business. However, although a person
who has a contagious disease may be covered by the Americans with Disabilities
Act (ADA), an employer would not have to hire or retain a person whose
contagious disease posed a direct threat to health or safety, if no reasonable
accommodation could reduce or eliminate this threat.
If an
individual with a disability cannot perform a marginal function of a job because
of a disability, an employer may base a hiring decision only on the
individual’s ability to perform the essential functions of the job, with or
without a reasonable accommodation.
