[Quality of life: an ethical and medical issue]

Quality of life as a criterion of evaluation of treatment and other medical activities was analysed with respect to meaning and the differences which occur in the understanding of quality of life by the physician and the patient. Attaining has been paid to these conditions under which the opinions of the physician and patient are common. It is proposed to accept the value of life as superior to quality of life. Realising such principle the possibility of compatibility of moral and pragmatic arguments could be expected in the use of quality of life as a criterion.
