Introduction of the quality of life concept in practical medicine

Abstract

The modern stage of medical development requires a multidisciplinary approach to studying the impact of treatment on human life. The social aspects are of great importance because the goal of treatment is to preserve or/and improve life. Therefore, the term "quality of life" is increasingly used in the world medical literature. The objectification of this indicator and its adaptation in practical medicine is a priority task. The concept of "quality of life" first appeared in 1958. In the future, this concept was developed in a research carried out by a group of professors at MIT (Massachusetts Institute of Technology) under Prof. R. Bauer in 1966. These researches initiated the quality of life study. In 1996, the WHO developed a definition of quality of life as an individual’s perception of their position in life in the context of the culture and value systems in which they live and in relation to their goals, expectations, standards and concerns. The purpose of studying the quality of life in the medical field was to introduce treatment protocols and standardize medical care. An important criterion for evaluating the quality of treatment was to compare changes in the patient’s quality of life before and after using a particular medical protocol. The main methods of studying changes in the patient’s quality of life were the use of special questionnaires. The most common general-purpose questionnaires for assessing changes in quality of life are SF-36, WHOQoL-100, Sickness Impact Profile, Nottingham Health Profile, EuroQoL-5D, EORTC QLQ-C30. In Ukraine, as of 2020, there is no local questionnaire for either general or specialized purposes. But there are translations of the main questionnaires, for example, SF-36, EORTC QLQ-C30. Developing own questionnaire that fully complies with the standards of the MAPI Research Institute requires multi-center and multidisciplinary research. The study of changes in the quality of life is an integral part of a comprehensive analysis of new methods of the diagnosis, treatment and prevention of diseases. Analysis of changes in the quality of life using different approaches to treatment is possible provided that general and special purpose questionnaires and available clinical data are used. Using advanced statistical processing of the questionnaire survey allows you to increase the reliability of the research. There is a need to develop own specialized adapted nosological questionnaires for quality of life analysis. Assessment of the quality of life should become one of the main criteria for the effectiveness of medical care, as well as an independent indicator of the condition of patients during medical and social expertise, determining the prognosis, treatment tactics, and developing rehabilitation programs.
