Risk management in health care refers to a diverse set of measures taken to improve the quality and safety of services for patients (1). The patient care environment consists of three parts, which include buildings, equipment and staff (2).
Various statistics on the incidence and prevalence of medical errors have been published in different hospitals. It is estimated that about one in 10 people admitted to a hospital experiences an unfortunate event, about half of which is preventable, and about one-third of the events cause harm to the patient, which can occur in a variety of ways. It varies from increasing the length of stay to death (3). Risk is the threat posed by an event or action that adversely affects an organization's ability to achieve its goals. In fact, risk management is the process of identifying, evaluating and controlling potential incidental risks, the specific consequences of which are damage or failure to change the status quo.
