[Regional Study of Patient Safety Incidents (ERIDA) in the Emergency Services]

Evaluate the patient safety incidents that occur in the emergency departments of our region.

Observational study conducted in all the hospital emergency departments in the Regional Health Service of Murcia. After systematic random sampling, data were collected during care and a week later by telephone survey. Health professionals of each service were trained and collected the information, following the methodology of the National Study of Adverse Events Related to Hospitalization -ENEAS- and the Adverse Events Related to Spanish Hospital Emergency Department Care -EVADUR-.

A total of 393 samples were collected, proportional to the cases treated in each hospital. In 10 cases (3.1%) the complaint was a previous safety incident. At least one incident was detected in 47 patients (11.95%; 8.7 to 15.1%). In 3 cases there were 2 incidents, bringing the number of incidents to 50. Regarding the impact, the 51% of incidents caused harm to the patients. The effects more frequent in patients were the need for repeat visits (9 cases), and mismanagement of pain (8 cases). In 24 cases (51.1%) health care was not affected, although 3 cases required an additional test, 11 cases required further consultation, and led to hospitalisation in 2 cases. The most frequent causal factors of these incidents were medication (14) and care (12). The incidents were considered preventable in 60% of cases.

A rate of incidents in the emergency departments, representative of the region, has been obtained. The implications of the results for the population means that 12 out of every 100 patients treated in emergency departments have an adverse event, and 7 of these are avoidable.
