Introduction. Patient safety is the absence of preventable harm to the patient in the course of medical care and the reduction of the risk of unnecessary harm associated with medical care to an acceptable minimum. Over the past two decades, the problem of patient safety has become the object and target area of public health for specific efforts to improve it.

The study aims to analyze modern scientific literature to consider problems related to clinical safety, the global burden of harming patients.

Material and methods. In the context of studying the problem, the results of modern research were used to identify the causes of medical errors and to find ways to prevent them.

Results. The desire to improve the level of safety and the quality of medical care is growing in the world. Consequently, significant measures to evaluate the safety of medical care and its quality will be of paramount importance. To date, there is no gold standard or established array of quality indices (QI) for measuring the quality and safety of medical care. However, many indices have been developed, and some have even been tested to measure specific aspects of patient quality and safety. Such studies are in demand to achieve a clinically significant reduction in the incidence of medical errors.

Conclusion. Despite the growing recognition of the role of human medical error in medicine, to prevent or mitigate their consequences requires the search for adequate ways both at the individual and systemic levels.
