This protocol will attempt to generate a detailed clinical profile of patients with funguria and identify subgroups of patients with funguria at high risk for candiduria and determine the relative risks for obtaining candiduria. In addition, it will look at identifying subgroups of patients with funguria at high risk for candidemia and identifying subgroups of patients with funguria at high risk for death. Finally, it will attempt to determine if funguria independently predicts fungemia or death. Data will be complemented by surveillance of a comparable population without funguria.
