目的：计算每分钟和每年急诊时间因素的货币值。方法：根据两种不同的时间因素计算救护车急救服务的货币值，即从急救医疗服务呼叫中心接到呼叫到急救团队到达急救现场的响应时间，以及包括到达医院的时间在内的操作时间。这项研究分两步进行。首先，计算了因时间因素改变1分钟而减少的伤亡人数的边际效应。其次，将边际效应和货币价值放在一起，得出每分钟的价值。结果：致死率为550万泰铢/分钟，重伤为32.6万泰铢/分钟。根据一年的总结，每次调度每改善1分钟的总货币价值为16亿泰铢，使用响应时间得出结论：计算的值可用于投资的成本效益分析，以减少响应时间。例如，类似研究的结果可与移动救护车站或投资新警报系统的成本进行比较。
Objective: To calculate the monetary value of the time factor per minute and per year for emergency services. Methods: The monetary values for ambulance emergency services were calculated for two different time factors, response time, which is the time from when a call is received by the emergency medical service call taking center until the response team arrives at the emergency scene, and operational time, which includes the time to the hospital. The study was performed in two steps. First, marginal effects of reduced fatalities and injuries for a 1-minute change in the time factors were calculated. Second, the marginal effects and the monetary values were put together to find a value per minute. Results: The values were found to be 5.5 million Thai bath/min for fatality and 326,000 baht/min for severe injury. The total monetary value for a 1-minute improvement for each dispatch, summarized over 1 year, was 1.6 billion Thai baht using response time Conclusions: The calculated values could be used in a cost-benefit analysis of an investment reducing the response time The results from similar studies could for example be compared to the cost of moving an ambulance station or investing in a new alarm system.
