An event study design was used to estimate adjusted rates of organ donation during the dates of 7 major US motorcycle rallies compared with the 4 weeks before and after the rallies in rally-affected and rally-unaffected (control) regions.

During the rally dates, there were 406 organ donors and 1400 transplant recipients. During the 4 weeks before and after the rallies, there were 2332 organ donors and 7714 transplant recipients. Donors and recipients during rally and nonrally dates were similar in demographic and clinical characteristics, measures of organ quality, measures of recipient disease severity, and recipient waiting time. During rallies, there were 21% more organ donors per day (incidence rate ratio [IRR], 1.21; 95% CI, 1.09-1.35;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u2009.001) and 26% more transplant recipients per day (IRR, 1.26; 95% CI, 1.12-1.42;\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&amp;amp;lt;\u2009.001) compared with the 4 weeks before and after the rallies in the regions where they were held.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"ab-ioi220069-10\">\n                    <jats:title>Conclusions and Relevance<\/jats:title>\n                    <jats:p>In this cross-sectional study, major motorcycle rallies in the US were associated with increased incidence of organ donation and transplants.
