Current through Register Vol. 48, No. 9, September 27, 2024
A.
Tuberculin skin testing is a diagnostic tool for detecting M.
tuberculosis infection. A small dose (0.1 mil) of purified protein
derivative (PPD) tuberculin is injected just beneath the surface of the skin
(by the intradermal Mantoux method), and the area is examined for induration
(hard, dense, raised area at the site of the TST administration) forty-eight to
seventy-two (48 to 72) hours after the injection (but positive reactions can
still be measurable up to a week after administering the TST). The size of the
indurated area is measured with a millimeter ruler and the reading is recorded
in millimeters, including zero (0) mm to represent no induration.
Redness/erythema is insignificant and is not measured or recorded. Authorized
healthcare providers are permitted to perform tuberculin skin testing and
symptom screening.
B. All
facilities shall conduct an annual tuberculosis risk assessment (See Section
101.BBB) in accordance with CDC guidelines (See Section 102.B.16) to determine
the appropriateness and frequency of tuberculosis screening and other
tuberculosis related measures to be taken.
C. The risk classification,
i.e., low risk, medium risk, shall be used as part of the risk
assessment to determine the need for an ongoing TB screening program for
staff/direct care volunteers and residents and the frequency of screening. A
risk classification shall be determined for the entire facility. In certain
settings, e.g., healthcare organizations that encompass
multiple sites or types of services, specific areas defined by geography,
functional units, patient population, job type, or location within the setting
may have separate risk classifications.
D. Staff/Direct Care Volunteers/Private
Sitters Tuberculin Skin Testing
1.
Tuberculosis Status. Prior to date of hire or initial resident contact, the
tuberculosis status of staff/direct care volunteer/private sitters shall be
determined in the following manner in accordance with the applicable risk
classification:
2. Low Risk:
a. Baseline two-step Tuberculin Skin Test
(TST) or a single Blood Assay for Mycobacterium tuberculosis
(BAMT): All staff/direct care volunteers/private sitters (within three
(3) months prior to contact with residents) unless there is a documented TST or
a BAMT result during the previous twelve (12) months. If a newly employed
staff/direct care volunteer or private sitter has had a documented negative TST
or a BAMT result within the previous twelve (12) months, a single TST (or the
single BAMT) can be administered and read to serve as the baseline prior to
resident contact.
b. Periodic TST
or BAMT is not required.
c.
Post-exposure TST or a BAMT for staff/direct care volunteers upon unprotected
exposure to M. tuberculosis: Perform a contact investigation
when unprotected exposure is identified. Administer one (1) TST or a BAMT as
soon as possible to all staff who have had unprotected exposure to an
infectious TB case/suspect. If the TST or the BAMT result is negative,
administer another TST or a BAMT eight to ten (8 to 10) weeks after that
exposure to M. tuberculosis ended.
d. Post-exposure TST or a BAMT for private
sitters upon unprotected exposure to M. tuberculosis: Written
evidence of a contact investigation when unprotected exposure is identified
shall be provided to the facility administrator. The private sitter shall
provide documentation of a completed single TST or a BAMT prior to resident
contact. If the TST or BAMT result is negative, the private sitter shall
provide written evidence of an additional TST or BAMT eight to ten (8 to 10)
weeks after that exposure to M. tuberculosis ended. (CDC:
Guidelines for Preventing the Transmission of Mycobacterium
tuberculosis in Health-Care Settings, December 30, 2005).
e. Baseline positive with or without
documentation of treatment for latent TB infection (LTBI) (See Section 101.BB)
or TB disease shall have a symptoms screen prior to employment and annually
thereafter.
f. Upon hire,
staff/direct care volunteers/private sitters with a newly positive test result
for M. tuberculosis infection (i.e., TST or
BAMT) or signs or symptoms of tuberculosis, e.g., cough,
weight loss, night sweats, fever, shall have a chest radiograph performed
immediately to exclude TB disease (or evaluate an interpretable copy taken
within the previous three (3) months). Repeat radiographs are not needed unless
symptoms or signs of TB disease develop or unless recommended by a physician.
These staff members/direct care volunteers/private sitters will be evaluated
for the need for treatment of TB disease or latent TB infection (LTBI) and will
be encouraged to follow the recommendations made by a physician with TB
expertise (i.e., the Department's TB Control
program).
3. Medium
Risk:
a. Baseline two-step TST or a single
BAMT: All staff/direct care volunteers/private sitters (within three (3) months
prior to contact with residents) unless there is a documented TST or a BAMT
result during the previous twelve (12) months. If a newly employed staff/direct
care volunteer/private sitter has had a documented negative TST or a BAMT
result within the previous twelve (12) months, a single TST (or the single
BAMT) can be administered to serve as the baseline prior to resident
contact.
b. Periodic testing (with
TST or BAMT): Annually, of all staff/direct care volunteers who have risk of TB
exposure and who have previous documented negative results. Instead of
participating in periodic testing, staff/direct care volunteers with documented
TB infection (positive TST or BAMT) shall receive a symptom screen annually.
This screen shall be accomplished by educating the staff/direct care volunteers
who have documented TB infection about symptoms of TB disease (including the
staff's and/or direct care volunteers' responses concerning symptoms of TB
disease), documenting the questioning of the staff/direct care volunteers about
the presence of symptoms of TB disease, and instructing the staff/direct care
volunteers to report any such symptoms immediately to the administrator.
Treatment for latent TB infection (LTBI) shall be considered in accordance with
CDC and Department guidelines and, if recommended, treatment completion shall
be encouraged.
c. Periodic testing
(with TST or BAMT): Annually, of all private sitters who have risk of TB
exposure and who have previous documented negative results. Instead of
participating in periodic testing, private sitters with documented TB infection
(positive TST or BAMT) shall provide the facility with written evidence of a
symptom screen annually. Documentation of education about symptoms of TB
disease (including responses concerning symptoms of TB disease) and written
evidence of the questioning about the presence of symptoms of TB disease, and
the report of any such symptoms shall be provided immediately to the facility
administrator.
d. Post-exposure TST
or a BAMT for staff/direct care volunteers upon unprotected exposure to
M. tuberculosis: Perform a contact investigation (See Section
101.M) when unprotected exposure is identified. Administer one (1) TST or a
BAMT as soon as possible to all staff/direct care volunteers/private sitters
who have had unprotected exposure to an infectious TB case/suspect. If the TST
or the BAMT result is negative, administer another TST or BAMT eight to ten (8
to 10) weeks after that exposure to M. tuberculosis
ended.
e. Post exposure
TST or a BAMT for private sitters upon unprotected exposure to M
tuberculosis: Written evidence of a contact investigation when
unprotected exposure is identified shall be provided to the facility
administrator. The private sitter shall provide documentation of a completed
single TST or a BAMT prior to resident contact. If the TST or BAMT result is
negative, the private sitter shall provide written evidence of an additional
TST or BAMT eight to ten (8 to 10) weeks after that exposure to M.
tuberculosis ended.
4. Baseline Positive or Newly Positive Test
Result:
a. Baseline positive with or without
documentation of treatment for latent TB infection (LTBI) or TB disease shall
have a symptoms screen prior to employment and annually thereafter.
b. Upon hire, staff/direct care
volunteers/private sitters with a newly positive test result for
M.tuberculosis infection (i.e., TST or BAMT)
or signs or symptoms of tuberculosis, e.g., cough, weight
loss, night sweats, fever, shall have a chest radiograph performed immediately
to exclude TB disease (or evaluate an interpretable copy taken within the
previous three (3) months). Repeat chest radiographs are not required unless
symptoms or signs of TB disease develop or unless recommended by a physician.
These staff members/direct care volunteers/private sitters will be evaluated
for the need for treatment of TB disease or latent TB infection (LTBI) and will
be encouraged to follow the recommendations made by a physician with TB
expertise (i.e., the Department's TB Control
program).
c. Staff/direct care
volunteers/private sitters who are known or suspected to have TB disease shall
be excluded from work, required to undergo evaluation by a physician, and
permitted to return to work only with written approval by the Department's TB
Control program. Repeat chest radiographs are not required unless symptoms or
signs of TB disease develop or unless recommended by a physician.
E. Resident
Tuberculosis Screening (I)
1. Tuberculosis
Status. Prior to admission, the tuberculosis status of a resident shall be
determined in the following manner in accordance with the applicable risk
classification:
a. For Low Risk and Medium
Risk:
1. Admission/Baseline two-step TST or a
single BAMT: All residents within thirty (30) days prior to admission shall
have completed the first step of the two step tuberculin skin test followed
seven to twenty one (7 to 21) days later by a second test unless there is a
documented TST or a BAMT result during the previous twelve (12) months. If a
newly-admitted resident has had a documented negative TST or a BAMT result
within the previous twelve (12) months, a single TST (or the single BAMT) can
be administered within one (1) month prior to admission to the facility to
serve as the baseline. As an exception, a resident may be admitted with at
least the first step of the TB screening process completed prior to admission
and the second step within fourteen (14) days of admission.
2. Periodic TST or BAMT is not
required.
3. Post-exposure TST or a
BAMT for residents upon unprotected exposure to M.
tuberculosis: Perform a contact investigation when unprotected
exposure is identified. Administer one (1) TST or a BAMT as soon as possible to
all residents who have had exposure to an infectious TB case/suspect. If the
TST or the BAMT result is negative, administer another TST or a BAMT eight to
ten (8 to 10) weeks after that exposure to M. tuberculosis
ended.
b.
Baseline Positive or Newly Positive Test Result:
1. Residents with a baseline positive or
newly positive test result for M. tuberculosis infection
(i.e., TST or BAMT) or documentation of treatment for latent
TB infection (LTBI) or TB disease or signs or symptoms of tuberculosis,
e.g., cough, weight loss, night sweats, fever, shall have a
chest radiograph performed immediately to exclude TB disease (or evaluate an
interpretable copy taken within the previous three (3) months). Routine repeat
chest radiographs are not required unless symptoms or signs of TB disease
develop or unless recommended by a physician. These residents shall be
evaluated for the need for treatment. If diagnosed with latent TB infection
(LTBI) the resident shall be encouraged to follow the recommendations made by a
physician with TB expertise (i.e., the Department's TB Control
program). For those residents diagnosed with TB disease, the facility shall
assure that the affected residents follow the recommendations made by a
physician with TB expertise (i.e., the Department's TB Control
program).
2. Residents who are
known or suspected to have TB disease shall be transferred from the facility if
the facility does not have an Airborne Infection Isolation room (See Section
101.E), required to undergo evaluation by a physician, and permitted to return
to the facility only with written approval by the Department's TB Control
program.
F. Individuals who have been declared in
writing to be in an emergency crisis stabilization status may be admitted to
the facility without the initial step of the two-step tuberculin skin test
and/or while awaiting the result of a BAMT. These individuals shall be placed
in an area separate from the general population. This admission to the facility
may be made provided:
1. There is
documentation at the facility of the declaration by Adult Protective Services
of the South Carolina Department of Social Services or the South Carolina
Department of Mental Health that the admission is, in fact, an emergency (NOTE:
Only these agencies may declare these crisis stabilization admissions to be an
emergency);
2. There is written
evidence of a chest x-ray within one (1) month prior to admission and a written
assessment by a physician or other authorized healthcare provider that there is
no active TB and a negative assessment for signs and/or symptoms of
tuberculosis; and,
3. The resident
will receive the initial step of the two-step tuberculin test within
twenty-four (24) hours of admission to the facility. The second step of the
two-step tuberculin skin test must be administered within the next seven to
fourteen (7 to 14) days.
