The effect of 2 population-based outreach screening strategies that used in-home sampling was compared with usual care practices for Chlamydia trachomatis infection. All 30,439 persons 21-23 years old in Aarhus County, Denmark, were divided randomly into 3 groups: group 1 (n=4500) had a home sampling kit mailed directly to their centrally registered home address; group 2 (n=4500) had a reply card mailed to their home address with which a home sampling kit could be ordered; and group 3 (n=21,439) had access to usual care. For women in groups 1 and 2, the relative risks of being tested were 4.1 (95% confidence interval [CI], 3.8-4.4) and 3.5 (95% CI, 3.2-3.9), respectively, compared with usual care. The corresponding figures for men were 19.1 (95% CI, 16.0-22.8) and 11.8 (95% CI, 9.8-14.2), respectively. Both screening strategies were highly effective, but men benefited the most from having the home sampling kit provided directly.
