Adverse Events (Medical Errors)

 

Adverse Events are ‘instances which indicate or may indicate that a patient has received poor quality care’ [2].  An AE is defined as ‘an injury that was caused by medical management (rather than the underlying disease) and that prolonged the hospitalization, produced a disability at the time of discharge, or both’ [3].

The Quality in Australia Health Care Study revealed that 16.6% of admissions were associated with an ‘adverse event’, which resulted in either disability or a longer hospital stay for the patient and was caused by health-care management. In 13.7% of these cases the disability was permanent and in 4.9% the patient died [15].  In UK, a study found that 10.8% of admitted patients experienced an AE [16].

In UK and Australia, about half of AE cases were considered preventable [15, 16]. The Hospitals for Europe’s Working Party on Quality Care in Hospitals estimated in 2000 that 10% of patients in European hospitals suffer from preventable harm and adverse effects related to his or her care [17]. An Australian study found that 17% of postoperative cases in a teaching hospital experienced at least one serious AE and that 7% of postoperative cases ended in the death of patient [18]. In Canada, it is estimated that the overall incidence rate of AEs is 7.5% of hospital admissions and that 37% of these AEs are potentially preventable [19].

In France, the incidence of AEs was estimated at 6.6 per 1000 hospital days in 2004, from which 24.1% were Hospital Acquired Infections.20 In Germany, the Dutch Patient Safety Research Program showed that AEs affect 5.7% of patients in Dutch hospitals [21].
