In this paper, we discuss a method for design of an ambulance stretcher which call decrease blood pressure fluctuation caused by ambulance acceleration. Recently, a lot of stretchers which can isolate the vertical vibration to reduce body resonances (4-10 Hz) have been used during ambulance transport. However, we have found that blood pressure of a patient laying in the stretcher fluctuates when the ambulance accelerates or decelerates. Since the enforced change of the blood pressure may deteriorate the patent's condition, a stretcher to cancel head-to-foot acceleration and to decrease the blood pressure variation (BPV) is expected for safe transport. We propose a method to design a stretcher which is tilted according to an adequate angle to cancel head-to-foot acceleration by gravity when the ambulance accelerates or decelerates. A control method of the stretcher is constructed by means of simulation analysis using acceleration data measured during ambulance transport. It is confirmed that the active controlled stretcher proposed has good performance for the BPV reduction.

Purpose: This study tests the validity of a standard evaluation tool of ambulance ride practices with new evaluation items and supports its application by 119 preceptors. Methods: We tested the validity of standard evaluation items collected from 19 on-site professionals assessing ambulance ride practices. New evaluation items, 'understanding of emergency rescue equipment' and 'ability to communicate', were added as additional criteria. The modified Delphi technique was used to test the three evaluation areas and ten evaluation items. We used the analytic hierarchy process to analyze the weighting value of the reconstructed evaluation tool model. Results: All three evaluation areas and 10 evaluation items within the standard evaluation tools used for ambulance ride practices corresponded with the consistency index, degree of convergence, and agreement in the modified Delphi panel. Conclusion: These results provide evidence of the consistency and usefulness behind preceptors' use of this standard evaluation tool in ambulance ride practice.

The ambulance service time interval, in particular the response time, has been used as an important indicator for the quality control of ambulance services in that it can be improved to increase the probability of survival and decrease the sequela-related disability. Based on the 2011~2014 Prehospital Care Reports in a metropolitan city, this study analyzed the time interval of ambulance services considering the patient's characteristics and chief complaints. If the definition of the time of ambulance services can be refined further, and a variety of economic and social factors and local characteristics would can be analyzed, the quality of the ambulance service is expected to be enhanced significantly.

Purpose: The purpose of this study was to provide an appropriate direction for effective field practice program by analyzing the influencing factors on satisfaction in ambulance ride practice of paramedic students in Korea. Methods: This study analyzed of 180 paramedic students from 20th to 30th september, 2019. The collected data were analyzed with MedCalc 18.1.0 program. Results: The results of the satisfaction of ambulance riding practice according to the degree of procedure practice are as follows. Satisfaction was high in all groups except the practice time. The lowest satisfaction rate was seen in the category of'There were many cases of applying theories learned at college'within the variable of practice environment(2.82±0.82). The factors affecting the satisfaction of ambulance riding practice were the nurse (β=-0.1472, p=.024) and emergency medical technician(β=-0.3318, p=.002) according to the ambulance worker qualification paramedic, and the practice score (β=0.0048, p<.001). Conclusions: For effective ambulance riding practice, it is necessary to be able to select the practice place where many cases can be experienced, the appropriate selection of the practice leader, and the degree of procedure practice.

Objectives: Changes in air temperature and its relation to ambulance transports due to heat stroke in all 47 prefectures, in Japan were evaluated. Methods: Data on air temperature were obtained from the Japanese Meteorological Agency. Data on ambulance transports due to heat stroke was directly obtained from the Fire and Disaster Management Agency, Japan. We also used the number of deaths due to heat stroke from the Ministry of Health, Labour and Welfare, Japan, and population data from the Ministry of Internal Affairs and Communications. Chronological changes in parameters of air temperature were analyzed. In addition, the relation between air temperature and ambulance transports due to heat stroke in August 2010 was also evaluated by using an ecological study. Results: Positive and significant changes in the parameters of air temperature that is, the mean air temperature, mean of the highest air temperature, and mean of the lowest air temperature were noted in all 47 prefectures. In addition, changes in air temperature were accelerated when adjusted for observation years. Ambulance transports due to heat stroke was significantly correlated with air temperature in the ecological study. The highest air temperature was significantly linked to ambulance transports due to heat stroke, especially in elderly subjects. Conclusions: Global warming was demonstrated in all 47 prefectures in Japan. In addition, the higher air temperature was closely associated with higher ambulance transports due to heat stroke in Japan.

Purpose: This study aimed to assess the appointment status of medical directors and the state of direct medical oversight in private ambulance services, including an analysis of the characteristics of the direct medical oversight requested by private ambulance services. Methods: This study investigated the appointment status of medical directors and direct medical oversight in private ambulance services based on official information disclosed by the National Emergency Medical Center and 17 local governments, along with 8,119 'Dispatch and Treatment Records' collected by a university hospital from 2020 to 2022. Results: Among 129 private ambulance services, 96.12% (124 agencies) had only one medical director, and 43.8% of the medical directors were Emergency Physicians. Over the past three years, the national average direct medical oversight request rate for private ambulance services was 34.68%. In 11.14% of the cases, records stated that EMS providers communicated with the medical director but did not receive direct medical oversight. Conversely, in 36.98% of cases, records incorrectly indicated that EMS providers did not communicate with the medical director but were noted as having received direct medical oversight (p<.05). Most private ambulance services request the direct medical oversight of a single director. Conclusion: This study highlights issues, such as the suitability of the medical director's specialty and inaccuracies in private EMS providers' methods for documenting Dispatch and Treatment Records.

Purpose: This study aimed to present the learning items of indirect practice as an alternative means of ambulance riding practice. Methods: Twelve on-site professionals participated in testing the effectiveness of learning items of utility value in indirect experience practice among the recommended learning objectives of ambulance ride practice using the modified Delphi technique. To validate the learning objectives, the Delphi technique was used to check content validity, and analytic hierarchy process (AHP) analysis was used to analyze the weighting value. Results: As the learning goal of indirect experience practice replaced the ambulance riding practice, four items were derived in consideration of practicality. These items were consistent with the Delphi panel's consistency index, convergence, and agreement. The first learning item to consider was 'Prevention of infection and risk of infection.' Conclusion: The results of this study are meaningful in that they propose the learning items that can achieve the minimum educational goal through indirect experience practice as an alternative means of ambulance training.

This study examined the socio-economic and clinical characteristics associated with the use of ambulance services among pregnant, childbearing, and postpartum women based on data from the 2008-2016 Korea Health Panel. The analysis revealed that among the pregnant, childbearing, and postpartum women, the proportion using all ambulance services was 18.9% whereas 12.0% used private and 119 ambulances. Moreover, among those using ambulance services, delivery was the most common reason (38.7%) followed by complications of labor and delivery (20.0%) and pregnancy with abortive outcome (17.3%). There were statistically significant differences between the users and non-users of ambulance services in terms of the average annual household income, emergency arrival time, and delayed arrival at the emergency room. As childbirth becomes more complicated due to low fertility and elderly mothers, the expansion and improvement of ambulance services as a social safety net for pregnant, childbearing, and postpartum women will become increasingly important.
