Patient safety - concept and characteristics of safety. The human factor impact

Anna Kircheva, Rumen Konstantinov


INTRODUCTION: We have learned over the past 15 years that patients can be harmed by many factors in the healthcare system or factors associated with healthcare providers. Healthcare emerges as one of the most un­safe industries. Studies show that in the developed countries approximately 10% of the hospitalized patients suffer an adverse event or incident. The global survey of unexpected harm conducted by WHO and the World Alliance for Patient Safety indicates that the most frequent incidents result from: healthcare-associated infec­tion (HCAI), medication errors, unsafe surgery, clinical handovers, injection safety.

AIM: The aim of this study is to do a systematic review on the existing practices and solutions applied in the period 2001 - 2016 with regard to patient safety. The issue has been systematically analyzed based on published results from the research work of WHO teams and leading authors on the subject.

RESULTS AND CONCLUSION: All applied programs of WHO concerning patient safety aim to coordinate actions, disseminate knowledge and accelerate improvements in patient safety worldwide. Patient safety is an issue that impacts all countries and all governments who provide health services.
