The scores are scored through the symptoms reported by the patient during the interview, the evaluator's observations and the information collected from third parties (relatives, nurses). The markings do not distinguish between the intensity and frequency of the symptoms, but these two should be equally at the discretion of the assessor. The scale covers the condition of the patient in the week preceding the mark for most symptoms, except for sleep disorders related to the last three days.Health-related quality of life is calculated using weighted questionnaires focusing on the general health level of the individual or the impact of specific diseases on the quality of life of the patient.
