One of the quality indicators in measuring the performance of the Emergency Department (IGD) is the response time of patient services in the ER, namely the speed of patient treatment which is calculated from the time the patient arrives until he receives treatment in less than 5 minutes (Decree of the Minister of Health of the Republic of Indonesia No: 856/Menkes/SK /IX/2009). Response Time of nurses in handling emergencies quickly and appropriately will increase satisfaction for patients and families of BPJS Health patients.
