Honest communication between oncologists and patients is important in alleviating the financial burden of cancer care. This study explored patient-relative-oncologist communication regarding the affordability of out-of-pocket (OOP) medication and the extent to which this communication addresses itself to the families' financial burden. A cross-sectional survey was conducted among primary caregivers of deceased cancer patients. About 43% of relatives said that they and/or the patients had paid out of pocket for medications during the last six months of the patient's life. Most (73%) oncologists suggested an OOP medication without asking about financial ability, 43% hardly explained the advantages of an OOP medication, and 52% hardly explained any treatment alternatives. Older age and female gender were related to less communication about an OOP medication, and better education, greater affluence, and having private health insurance were related to more communication. About 56% of relatives said that OOP payment for medications inflicted a very heavy or heavy financial burden on patients and their households. Physicians' interest in financial ability and giving explanation lightened the burden. Given the difficulty of explaining the complex interactions of cost and clinical outcomes, oncologists need to be better educated in skills that would enable them to communicate costs more openly and should consider the cost of a treatment when prescribing it.
