Background
About Cerebral Hemorrhage
Cerebral hemorrhage, one of the most common types of strokes, is a condition in which a cerebral artery breaks and bleeds into the brain due to hypertension, brain tumors, or abnormalities in cerebral blood vessels. Nerve cells in the brain may be compressed by bleeding in various locations, causing symptoms such as headache, limbs paralysis, or loss of consciousness. When these symptoms are observed, a head CT scan is performed to determine the location and amount of bleeding from the findings of white-appearing areas (high attenuation areas) compared to the surrounding normal structures. Thus, a definitive diagnosis is made.
About Cerebral Hemorrhage and emergency medical care
Depending on the severity of illness/injury and the urgency, patients are divided into three levels (primary, secondary, or tertiary) of emergency care. Patients categorized into the secondary emergency care are delivered to a medical facility, where doctors with extensive knowledge and experience in emergency medicine can provide inpatient care, including treatment and surgery, 24 hours a day.
As of October 2017, there are 4,006 facilities for secondary emergency care in Japan[1], and they are the most widely established.
For treatment of strokes such as cerebral hemorrhage, while tertiary emergency care facilities accept critically ill patients, secondary emergency care facilities have also played a significant role, treating 60% of such cases[2].
Accordingly, the following issues have become apparent.
Strengthening the system for secondary emergency care
Approximately 70% of hospitals have only one doctor in charge of on-call emergencies[3], and in some cases non-specialized doctors have to diagnose cerebral hemorrhage. This system may cause a risk of oversight, and there is a need to establish a better system in light of limited medical resources.
Reducing emergency department overuse
It has been pointed out that physicians at emergency department spend more time in the clinic and are on duty more often than those at other departments[4]. Thus, creating an environment supporting unskilled physicians is expected to reduce overused physicians in emergency departments.
