2.1. The Four T’s of Emergency Medical Treatment
Four factors in medical treatment—the four T’s—significantly affect patient prognosis:
Telecommunication
Transportation
Triage
Early Treatment
Emergency medical treatment can proceed smoothly only when broadband mobile telecommunications, ambulances, triage, and early treatment work effectively and in concert. Effective early treatment improves patient prognosis and reduces medical costs. For the past 20 years, lots of experimental and practical operation have been reported and published in the field of ambulatory applications (Preston, 1995; Ricci, Caputo, & Amour, 2003; Ellis & Mayrose, 2003; Tachakra, Wang, & Robert, 2003; Meystre, 2005; Tang, Johnson, & Douglas, 2006; Sibert, Ricci, & Caputo, 2008; Su, Ma, & Chow-In Ko, 2008; Pan, Cusack, & Hook, 2008; LaMonte, Bahouth, & Xiao, 2008; Belala, Issa, & Gregoire, 2008; Nakajima & Tomioka, 2009; Hsieh, Lin, & Wu, 2010; Costa, Rodrigues, & Reis, 2010; Lee, Kim, & Lee, 2011; Kim, Lee, & Kim, 2011).
