Introduction and Background: A critical lab result is defined as an imminent life-threatening laboratory result requiring immediate physician notification and action plan. It was found, that high number of delayed critical lab results incidents were reported through Electronic Incidents Report System (EIRS). This issues was associated mainly with delays in treatment ,poor communication, and documentation issues. Analysis of our current processes at HGH to determine what strategies (Ex, to identify, document, and communicate critical lab results) may be necessary to improve patient safety and quality of care. Aim: To decrease the number of reported incidents through (EIRS) from 13% to 0% which will lead to improve the health care system that provided to the patients and to decrease number of missing critical lab result which might affect patient safety. Interventions: Writing the number of sending labs area clearly and clear stamp of the doctor who requested the tests. Started to use a unified bleep number for reporting any critical lab result after duty hours. Created a new form to be used by the senior on call physician to document the received critical lab value and the action was done. Conclusion and outcome: After implementation first action plan there was significant decrease in the reported OVA in Mar 2015 , but it start to rising again .implementing the 2nd action plan in May 2015 had lead to significant drop of the reporting incidence of (OVA) and decrease number of missing critical lab result which lead to improve patient safety.
