For those found to be tuberculin reactors at entry, the choice was for isoniazid treatment or no treatment. For those without tuberculin reactivity, the choice of screening intervals was 6 months, 1 year, 2 years, or 5 years. Outcomes measured were tuberculosis cases, death, life expectancy, and cost. Assumptions were derived from published data and analyses.<\/jats:p><\/jats:sec><jats:sec id=\"S0195941700077456_abs3\"><jats:title>Results:<\/jats:title><jats:p>Treatment of initial reactors with isoniazid in all three risk groups was associated with a net savings of $14,800 to $15,700 for each tuberculosis case prevented. For those without evidence of infection at entry, the most cost-effective screening interval was 1 year for high-risk groups, 2 years for moderate-risk groups, and 5 years for low-risk groups, with a net savings $0.20 to $26 per HCW per year. Screening at a more frequent interval was still cost-effective.<\/jats:p><\/jats:sec><jats:sec id=\"S0195941700077456_abs4\"><jats:title>Conclusions:<\/jats:title><jats:p>For HCWs found to be tuberculin reactors, treatment of their latent infection is to their benefit and is associated with a net cost-savings. Regular tuberculin screening of HCWs can be cost-effective or result in a net cost-savings. Each institution could use its own skin test surveillance data to create an optimum screening program for its employees. However, for most HCWs, a 1-year screening interval would be a cost-effective and safe choice.<\/jats:p><\/jats:sec>","DOI":"10.1086\/502343","type":"journal-article","created":{"date-parts":[[2006,4,14]],"date-time":"2006-04-14T18:39:15Z","timestamp":1145039955000},"page":"1056-1061","source":"Crossref","is-referenced-by-count":18,"title":["Screening and Treatment of Latent Tuberculosis Among Healthcare Workers at Low, Moderate, and High Risk for Tuberculosis Exposure: A Cost-Effectiveness Analysis"],"prefix":"10.1017","volume":"25","author":[{"given":"Shelley R.","family":"Salpeter","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Edwin E.","family":"Salpeter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2015,1,2]]},"reference":[{"key":"S0195941700077456_ref045","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-6553(96)90054-1"},{"key":"S0195941700077456_ref023","first-page":"1","article-title":"Targeted tuberculin testing and treatment of latent tuberculosis infection","volume":"49","year":"2000","journal-title":"MMWR"},{"key":"S0195941700077456_ref039","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.156.1.9611091"},{"key":"S0195941700077456_ref012","first-page":"935","article-title":"A controlled trial of community-wide isoniazid prophylaxis in Alaska","volume":"95","author":"Comstock","year":"1967","journal-title":"Am Rev Respir Dis"},{"key":"S0195941700077456_ref003","first-page":"340","volume-title":"Tuberculosis in the Workplace","author":"Field","year":"2001"},{"key":"S0195941700077456_ref033","doi-asserted-by":"publisher","DOI":"10.1086\/319993"},{"key":"S0195941700077456_ref006","first-page":"1","article-title":"Guidelines for preventing the transmission of Mycobacterium tuberculosis in health-care facilities, 1994","volume":"43","year":"1994","journal-title":"MMWR"},{"key":"S0195941700077456_ref005","doi-asserted-by":"publisher","DOI":"10.1164\/ajrccm.154.3.8810591"},{"key":"S0195941700077456_ref020","first-page":"555","article-title":"International Union Against Tuberculosis Committee on Prophylaxis.
