Introduction: This study is intended to address the emic perspective of cardiac arrest resuscitation teams and the organizational and educational approaches that would best support their functioning. Objectives: The specific objectives of this study are as follows:

1. To describe the emergency response events within and outside the hospital.
2. To identify organizational factors in order to improve cardiac arrest resuscitation training, teamwork and patient care.

Material and Methods: The present study is a longitudinal analysis of secondary data collected from patients in Mumbai, India. The data was collected from the Emergency response Closure form filled by the ICU Intensivist after the emergency for patient from within the healthcare setting. The hospital follows the CPR policy for medical emergencies from within the healthcare setting. Result: Though in our study the results shows that there was no significant difference in the neurological outcome of patient of calls from within the hospital and outside the hospital. The variable of age in this study depicted that the emergency calls from outside the hospital were patient aged more than 60 years, than from within the hospital emergency calls. A study has also suggested that with increasing challenges of aging population, the crude annual rate of emergency transportations across all age groups increased from 32 per 1000 people in 1994–95 to 58 per 1000 people in 2007–08. The rate of transportation for all ages increased by 75% (95% CI, 62%–89%) over the 14-year study period, representing an average annual growth rate of 4.8% (95% CI, 4.3%–5.3%) beyond that explained by demographic changes. Patients aged ≥ 85 years were eight times (incident rate ratio, 7.9 [95% CI, 7.6–8.3]) more likely to be transported than those aged 45–69 years over. The study also reflects that most of the emergency calls from outside the hospital were due to cardiovascular emergency. The study results also show that the response time to outside emergency calls took more time as compared to internal call. The response time to internal calls was 1min as compared to external calls of 20 mins.
