We implemented an algorithm to link these \u201csentinel patients\u201d with household members in the database. We determined rates and predictors of TST\/IGRA testing, test positivity, and treatment prescription among household members.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>We identified 35 772 sentinel patients with a positive TST or IGRA, who were linked to 129 432 household members. Of household members, 33 821 (26.1%) had a TST\/IGRA within 2 years of the sentinel patient's positive test, of whom 3127 (9.3%) had a positive test and 641 (20.6%) were prescribed TB infection treatment. Whether the sentinel patient was prescribed treatment was associated with household member being tested (adjusted odds ratio [aOR] 1.16 [95% confidence interval {CI}: 1.10\u20131.21]) and being prescribed treatment (aOR 9.68 [95% CI: 7.71\u201312.16]).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Most household members had no documented TB infection test before or within 2 years after a sentinel patient in the household had a positive test. Household member and sentinel patient characteristics, conditions, and treatment were associated with household member testing, test positivity, and treatment prescription.
