Introduction
Transportation time by ambulance is one of the important factor of evaluating emergency medical service. But, the previous researches about the relation of transportation time and socioeconomically condition by district is insufficient.
Objectives
We estimate an average transportation time and a ratio of daytime to nighttime in a transportation time in each district using various district socioeconomically indicators as independent variables.
Method
The dataset includes 3,538,275(71.9%) emergency patients who used emergency transportation by ambulance in 2011 and 587 districts. The independent variables for each district included a geographical component variable (population density and so on), ratio of transportation to another district, ratio of public hospital to emergency hospital, ratio of emergency patients to population, population aging rate and traffic congestion. We estimate two indicator by these independent variables for OLS.
Result
For the estimated transportation time (Adj.R-Squared = 0.294 P<.001), ratio of transportation to another district (P<.01), population aging rate (P<.01) and traffic congestion (P<.001) showed positive correlations. Geographical component variable (P<.001) and ratio of public hospital (P<.001) showed negative correlations. For the estimated a ratio of daytime to nighttime in a transportation time (Adj.R-Squared = 0.308 P<.001), geographical component variable (P<.001), ratio of transportation to another district (P<.001) and traffic congestion (P<.1) showed positive correlations, while ratio of public hospital (P<.01) showed negative correlations.
Conclusions
The result shows that a transportation time is longer in rural than urban and a ratio of daytime to nighttime in a transportation time is higher in ur ban than rural. These are the geographic subjects in emergency medical system. And, a transportation time and a ratio of daytime to nighttime are more influenced supply side factor rather than demand side. To solve the subjects, supply of emergency medical for elderly people is needed, because elderly people who is one of a cause of the subjects is increasing year by year in Japan.
