Factor	Physicians’ estimate (%) N = 375	Oncology nurses’ estimate (%) N = 186	Patients’ rating N = 386
Are reluctant to add to their overall medication/pill burden	27.4	26.9	5.4

Data presented for physicians and oncology nurses are mean estimates of the percentage of patients that do not adhere to their anti-emetic regimen for the given reason. Data presented for patients is the mean rating that a factor discourages them from using anti-emetic medication on a scale of 1–10, where 1 is not at all and 10 is strongly
