Behind the medical reform: Why are more and more countries introducing physician assistants?
Globally, healthcare demands continue to rise, especially in the face of an aging population and an ongoing physician shortage. As these challenges emerge, the introduction of the physician assistant (PA) role becomes increasingly important. The profession was first established in the United States in the 1960s, and since then, more and more countries around the world have begun to recognize the value that physician assistants bring.
Physician assistants are highly qualified medical professionals who play an important role in the healthcare team, assisting doctors in diagnosing and treating patients and improving access to healthcare services.
The implementation of the physician assistant role varies widely across countries. In the United States, physician assistants have relatively high autonomy and can diagnose diseases, develop and manage treatment plans, prescribe medicines, etc. Additionally, many states require physician assistants to have a direct agreement with a physician. However, in other regions, such as the United Kingdom, physician assistants are required to work under the supervision of a doctor and cannot prescribe medicines or order certain types of tests.
This profession originated at Duke University in the United States in 1967 as an accelerated training program designed to address the shortage of medical manpower. Over time, this model has been widely used and recognized in many countries, especially in Canada, Germany, Israel and India. Physician assistant training and roles vary across these countries, but basic duties remain similar, such as taking medical records, performing physical examinations, and interpreting test results.
The duties of a physician assistant are equivalent to some functions that have traditionally only been performed by doctors, making this profession particularly important in improving the efficiency of medical services.
Possibilities for expanding medical services
As pressure on healthcare delivery systems grows around the world, the introduction of the physician assistant system is seen as a solution. For example, in Canada, the number of physician assistants has increased year by year and is considered an effective way to alleviate the shortage of medical resources. According to the latest statistics, by 2024, there will be approximately 1,000 physician assistants working in various medical institutions in Canada.
In Germany, demand for this role has gradually increased since the establishment of physician assistant degree programs in 2005. Despite slow early recruitment, hundreds of thousands of physician assistants have begun working in Germany's healthcare system in recent years. Their main task is to help the medical team provide timely medical care.
The key to the success of medical reform lies in the balance between medical quality and accessibility, and the introduction of physician assistants is a step towards this goal.
Regulations and training in different countries
The differences in professional standards and training content for physician assistants in different countries also reflect the differences in local medical policies. In the United Kingdom, for example, physician assistants are supervised by doctors, still require legal protection, and training is currently conducted through master's degree programs. Meanwhile, physician assistants in Japan are trained under specific conditions and may take into account the diversity of health care.
In Canada, the educational requirements for physician assistants are usually three years of professional graduate university education involving medical and pharmaceutical knowledge. This is designed to ensure that physician assistants maintain high standards when providing medical services.
The Impact of Physician Assistants on the Healthcare SystemWith the need to improve the efficiency of medical services in the future, the role of physician assistants will become more important. The ability for these professionals to collaborate in important areas such as emergency medicine, surgery and cardiology and to provide support in the care of patients is critical to protecting public health.
In fact, physician assistants can also alleviate the pressure on the medical system by providing specific medical services and further enhance the stability of the medical system. As they gain traction, the job functions of physician assistants continue to expand, allowing a wider range of patients to benefit from high-quality medical services.
With limited resources, can physician assistants become a key factor in driving global healthcare reform?
