Second, the categories for age, call-to-response time, and call-to-hospital arrival time were made on the basis of the IQR of each variable.
Age, call-to-response time, and call-to-hospital arrival time in the survival cohort were significantly lower than those in the death cohort (P <0.0001).
The call-to-response time interval was calculated as the time from the emergency call to the time of vehicle arrival at the scene.
The call-to-response time was calculated as the time from the emergency call to the time of vehicle arrival at the scene.
Although call-to-response time was an independent factor associated with 1-month CPC 1 to 2, the adjusted OR was less than that of call-to-hospital arrival time in our analytic model (Table 3).
Call-to-response and call-to-hospital arrival times in the CPC 1 to 2 cohort were significantly shorter that those in the CPC 3 to 5 cohort by approximately 1 minute and 4 minutes, respectively.
Call-to-response and call-to-hospital-arrival times in the survival cohort were significantly lower than those in the death cohort.> -wrap-foot> Varees areportedted as number unless indicated otherwise.
Among patients who received prehospital epinephrine, call-to-response time and epinephrine administration time in the initial shockable rhythm cohort were significantly shorter than in the initial nonshockable rhythm cohort (all P < 0.0001).
Call-to-response and call-to-hospital-arrival times in the CPC 1 2 cohort was shorter that those in the CPC 3 5 cohort.> -wrap-foot> Varees areportedted as number unless indicated otherwise.
The 11 selected variables included year, age, gender, witnessed arrest, bystander CPR, arrest presumed cause, initial cardiac rhythm, prehospital shock delivery, advanced airway management, call-to-response time and pre-hospital epinephrine administration for the model as an independent variable.
