To determine the willingness of eligible patients to be randomized, a screening log documenting the number of eligible subjects approached for participation will be maintained. Subjects who are approached but who decline participation will undergo a short interview by the Clinical Research Associate as to the reason for non-participation. The Clinical Research Associate will read from a script with statements to make sure that subjects who refuse the trial know that they are free to provide or not provide the reasons for declining the trial and that their answers will not affect the care they will receive. They will be asked to list up to five reasons for non-participation in the trial. At the conclusion of the trial, qualitative analyses will be done for the reason of non-participation.
