We are under pressure to reform the social security system and work styles. To realize these reforms and basic principles, we need to understand the current environment surrounding the hospital and consider future measures. We report on the problems identified as a result of our investigation of the medical environment in the South West Mikawa West Medical Region and our hospital, and propose the use of emergency medical technicians (EMTs) as a solution to these problems. We examined data from the National Census, the Japan Medical Association Research Institute for General Policy Studies, the Fire and Disaster Management Agency of the Ministry of Internal Affairs and Communications, and our hospital’s management meeting. In this medical area the population aged 65 years or older and the demand for medical care are projected to increase toward the year 2045. On the other hand, the number of physicians and nurses per 100,000 population in this medical region is below the national average. Almost no change was seen in the number of patients coming to the hospital by ambulance or the number of emergency admissions by ambulance, and their admission rates did not change significantly over the past 5-year period. However, the rate of unfilled ambulance demand increased, due to the impact of full beds. Of the total number of emergency ambulance admissions, the rate of moderately ill patients averaged 74% over the 5-year period. The number of inpatient transfers in 2022 decreased by 25.5% (176) compared to that in 2019 due to the lack of personnel to transport patients. As the demand for medical care increases toward 2045, we need to reduce the rate of unfilled ambulance demand while at the same time reforming work styles to create a more comfortable workplace for healthcare workers. To achieve these goals, key tasks may be to review the transfer transport system for moderately ill patients and to expand the role of EMTs.

Even within a hospital, the prognosis after a cardiac arrest is extremely poor if intervention starts only after the event; thus, early recognition and intervention is crucial to reduce inhospital cardiac arrests. This paper aims to assess the results of in-clinic surveys conducted for the implementation of the Rapid Response System (RRS) at our hospital and changes in awareness after awareness initiatives. Excluding the neonatal intensive care unit, all wards were targeted for implementation, with the creation of criteria for requesting the RRS and hospital-wide awareness initiatives. Four items were defined for the request criteria—namely, (1) respiration, (2) circulation, (3) state of consciousness, and (4) others (any concerns)—with a request being warranted if any one of these criteria was met. A pre-awareness survey revealed that respiratory rates were recorded only 6.9% of the time on average, indicating inadequate observation of respiratory rates across all wards. In response to this issue, we announced that respiratory status should be observed at least once a day, which resulted in the recording rate improving to 68.2% after 2 months. Survey results before and after the awareness initiatives among doctors and nurses showed a significant increase in RRS awareness. The percentage of nurses who answered “well aware” or “somewhat aware” increased from 34.8% to 77.6%, and from 63.4% to 88.0% among doctors. However, while the introduction of the RRS was relatively well-received by nurses struggling with on-site responses, some doctors questioned the necessity of the RRS. Upon implementation, it is important to make it known that it is a hospital-wide effort. Simplifying and thoroughly utilizing the request criteria can lead to early recognition of abnormalities. Since it is not easy to gain doctors’ understanding, it is necessary to listen to the needs and requests of each department and patiently continue awareness activities before implementation
