Evaluation of quality of life in patients with thyroid disease with syndrome hyperthyroidism as criterion of surgical treatment

The number of people with thyroid disorders was growing during the last decades in the whole world. Thyrotoxicosis is a complication of thyroid disorders which sufficiently worsens the course of the disease. Thyrotoxicosis causes complications itself and that affects the disease prognosis and patients life quality. At the same time there are reports showing that patient-reported quality of life doesn’t always grow in concordance with clinical findings registered by the physician, or with multiple laboratory and instrumental data. The quality of life as a medical term was first used in the 1960-s, and is nowadays binded with the definition of "health” given by the WHO in 1986. In evidence-based medicine quality of life assessment is used in treatment effectiveness analysis. According to the statistics, surgical treatment is mostly used in Russia for these patients. For a proper assessment of patients’ quality of life after surgical treatment, measurements should be performed at different time-periods after the operation. Quality of life assessment before and after the treatment gives us an insight into the field previously completely unavailable for quantitative measurement. Although clinical outcomes of modern thyrotoxicosis treatment are generally favorable, there is lacking data on quality of life changes after the treatment. This does not allow to say about the patients’ satisfaction with the modern thyrotoxicosis treatment, there is need for a more detailed assessment of patient-reported outcomes.
