Adverse events are still one of the major issues for healthcare organisations even though many initiatives have been launched in the past for patient safety. There are many reasons of patient safety incidents and avoidable harms to service users, such as human factors, medical factors, system wide problems, lack of technology, poor communication and teamwork. By developing and implementing proper system, effective teamwork, good communication channels and means, standardised procedural documents, patient safety training and education programme, healthcare professionals and institutions can deliver safe patient care and improve the quality of healthcare.
