H. HCWs with active tuberculosis disease HCWs are unable to work until they are non-infectious. Documentation<br />

must be provided showing two weeks of effective therapy for active pulmonary tuberculosis are complete with a<br />

good clinical response. The HCW is cleared to continue patient care/work when the infectious status is known to<br />

be non-communicable.<br />

I. HCW NON-COMPLIANCE HCW compliance with Tuberculosis Screening programs is mandatory. This<br />

includes: pre-placement tuberculosis screenings and 2 step PPD testing, annual tuberculosis screening, increased<br />

risk department semi-annual tuberculosis screening, and post-exposure tuberculosis screening.<br />

1. Employee Health manager or physician will notify Human Resources or the department director that the<br />

HCW is not compliant. Human Resources or the department director will proceed according to individual<br />

company policy to resolve the non-compliance issues. Depending on company policy the HCW may be<br />

relieved from duty until the compliance issue is resolved.<br />

2. The Employee Health manager or physician will notify Human Resources when the HCW is compliant.<br />

groups:<br />

a. HIV-infected persons<br />

b. Recent contacts of TB case<br />

c. Persons with fibrotic changes on chest radiograph consistent with old healed TB<br />

d. Patients with organ transplants and other immunosuppressed patients (receiving the equivalent of > 15<br />

mg/day of prednisone for > 1 month).<br />

2. A tuberculin reaction of 10 millimeters or greater of induration is classified as positive in persons who do not<br />

meet the preceding criteria but who have other risk factors for Tuberculosis. These include:<br />

a. Recent arrivals to the U.S. (< 5 years) from high-prevalence countries<br />

b. Injection drug users<br />

c. Residents and employees of high risk congregate settings (correctional facilities, nursing homes, homeless<br />

shelters, SLUCares, residential facilities)<br />

d. Mycobacteriology laboratory personnel<br />

e. Persons with medical conditions that place them at high risk (HIV infection; substance abuse; recent<br />

infection with M. tuberculosis; chest radiograph findings suggestive of previous TB; diabetes mellitus;<br />

silicosis; prolonged corticosteroid therapy and other immunosuppressive therapy; cancer of the head and<br />

neck; hematologic and reticuloendothelial diseases; end-stage renal disease; intestinal bypass or<br />

gastrectomy; chronic malabsorption syndromes; or low body weight)<br />

f. Children < 4 years of age<br />
