Current through Reg. 49, No. 38; September 20, 2024
Screening for tuberculosis (TB) in institutional settings
usually involves testing for latent tuberculosis infection (LTBI) and
additional evaluation of those who are infected. In some correctional
facilities, it may be more practical to screen with chest x-rays to identify
individuals with lung abnormalities suggestive of pulmonary tuberculosis. While
the chest x-ray method is more expensive, it can be an acceptable technique to
identify and segregate tuberculosis suspects; however, use of the chest x-ray
screening method on intake is to be followed by testing for latent TB infection
within 14 days.
(1) Tuberculin skin
test.
(A) The tuberculin skin test utilizing
purified protein derivative (PPD) is the standard method of identifying persons
infected with Mycobacterium tuberculosis, the causative agent
of TB. The intradermal Mantoux PPD test, not a multiple puncture test, shall be
used to detect latent tuberculosis infection.
(B) The Mantoux PPD test is the only type of
testing material that is supplied by the Texas Department of Health
(department).
(2)
Administration of tests.
(A) The Mantoux PPD
test can be applied by anyone properly trained in tuberculin skin testing
procedures including applying, reading, and interpretation.
(B) Unlicensed personnel should be supervised
by licensed health care workers according to the requirements of the Board of
Medical Examiners and Board of Nurse Examiners in conformity with the Texas
Medical Practice Act and the Nurse Practice Act, §218.11, and other
applicable laws.
(3)
Interpretation of tests for latent tuberculosis infection.
(A) The Mantoux PPD test shall be read 48 to
72 hours after injection. However, if the person is not available for the
scheduled reading, positive reactions may still be measurable up to one week
after testing. The reading shall be based on measurement of induration
(palpable swelling), not erythema (redness). The diameter of induration shall
be measured transversely to the long axis of the forearm and recorded in
millimeters.
(B) A reaction of 5 mm
or greater shall be considered positive in persons who are human
immunodeficiency virus (HIV) infected, who are recent contacts to TB cases, who
have apical fibronodular infiltrates on chest x-rays consistent with prior
tuberculosis, or persons with organ transplants and other immunosuppressed
persons receiving the equivalent of 15 mg/d or greater of prednisone for 1
month or more. All other persons tested in a correctional facility will be
considered positive if their skin test reaction is 10 mm or greater.
(C) Absence of a reaction to the tuberculin
test does not exclude the diagnosis of TB or latent TB infection. Persons who
have symptoms consistent with active tuberculosis shall be evaluated for
disease even if they have a negative skin test.
(D) The PPD test can be read by anyone
properly trained in tuberculin skin testing procedures including applying and
reading.
(E) Positive tuberculin
reactions in Bacillus Calmette-Guerin (BCG)-vaccinated persons usually indicate
infection with TB. Such persons shall be evaluated for treatment of latent TB
infection. Skin tests shall be interpreted without regard to a history of BCG
vaccination.
(4) Scope.
Skin test screening for tuberculosis shall be performed on employees and
volunteers as well as inmates of county jails and correctional facilities as
follows.
(A) Employees.
(i) Employees who share the same air with
inmates shall be screened at time of employment and at least annually
thereafter according to this section unless the employee or volunteer is exempt
as described in clauses (ii), (iii), or (iv) of this subparagraph. A
certificate or similar document may be used to record results. The recommended
certificate is located in §
97.179 of
this title (relating to the Tuberculosis Record).
(ii) Employees with a history of a positive
tuberculin skin test shall provide documentation of the test and any
appropriate medical follow-up or a certificate signed by a physician or
registered nurse. The documentation shall be included in the certificate or a
similar document.
(iii) Employees
are exempt from screening if the screening conflicts with the tenets of an
organized religion to which they belong.
(iv) Employees may be exempt from screening
if medically contraindicated based on an examination signed by a physician. The
only valid contraindication is a documented history of severe reaction to a
tuberculin skin test.
(v) Employees
with a history of negative skin tests who are close contacts to a known or
suspected case of TB shall be skin tested after exposure. If the test is still
negative, they shall be retested 90 days after break in contact with the known
or suspected case of TB occurs.
(B) Volunteers.
(i) All volunteers who share the same air
space with inmates on a regular basis (more than 30 hours per month) shall be
screened prior to becoming a volunteer and at least annually thereafter
according to this section unless the volunteer is exempt as described in
clauses (ii), (iii), or (iv) of this subparagraph. A certificate or similar
document may be used to record results. The recommended certificate is located
in §
97.179 of
this title.
(ii) Volunteers with a
history of a positive tuberculin skin test shall provide documentation of the
test and any appropriate medical follow-up or a certificate signed by a
physician or registered nurse. The documentation shall be included in the
certificate or a similar document.
(iii) Volunteers are exempt from screening if
the screening conflicts with the tenets of an organized religion to which they
belong.
(iv) Volunteers may be
exempt from screening if medically contraindicated based on an examination
signed by a physician. The only valid contraindication is a documented history
of severe reaction to a tuberculin skin test.
(v) Volunteers with a history of negative
skin tests who are close contacts to a known or suspected case of TB shall be
skin tested after exposure. If the test is still negative, they shall be
retested 90 days after break in contact with the known or suspected case of TB
occurs.
(C) Inmates.
(i) With the exception of those inmates who
meet the criteria in clauses (iii), (iv) or (v) of this subparagraph, all
inmates who reside (or are expected to reside) in the facility for seven days
or longer shall be screened according to this section. A certificate or similar
document may be used to document results. The recommended certificate is
located in §
97.179 of
this title (relating to Tuberculosis Record).
(ii) Every inmate shall have a screening test
on or before the seventh day of incarceration and at least annually thereafter
if the inmate is not known to be a previous positive reactor.
(iii) Every inmate must have a screening test
unless the inmate has documented results of at least one screening test during
the previous 12-month period or documented history of a positive tuberculin
skin test. An inmate with a history of a positive tuberculin skin test shall
provide documentation of the test and any appropriate medical follow-up. The
documentation shall be included in the certificate or a similar
document.
(iv) Inmates are exempt
from screening if the screening conflicts with the tenets of an organized
religion to which they belong.
(v)
Inmates may be exempt from screening if medically contraindicated based on an
examination signed by a physician. The only valid contraindication is a
documented history of severe reaction to a tuberculin skin test.
(vi) Inmates with a history of negative skin
tests who are close contacts to a known or suspected case of TB shall be skin
tested after exposure. If the test is still negative, they shall be retested 90
days after break in contact with the known or suspected case of TB
occurs.
(5)
X-ray screening programs.
(A) Correctional
facilities may elect to perform chest x-rays on inmates on intake instead of a
skin test screening program; however, use of the chest x-ray screening method
on intake is to be followed by testing for latent TB infection within 14
days.
(B) If inmate chest x-rays
screening is done on inmates, the requirement for skin test screening of staff
and volunteers will remain in effect.
(6) Frequency of screening tests.
(A) Frequency. Annual (or more frequent)
tuberculosis (TB) screening of employees, volunteers, or inmates is required.
When a specific situation indicates an increased risk of transmission, more
frequent TB screening is recommended.
(B) Repeat tests. Employees or volunteers who
have a verified record of a previous positive test for TB do not have to have
repeat tests.
