With the deepening development of reform and opening up and socialist market economy. The management system and operation mechanism of the hospital are changing, and so are the ideas, values and moral standards of medical staff. The competitive consciousness, enterprising consciousness and economic consciousness of medical staff have been obviously improved. At the same time, it has also produced some negative effects. The traditional concept of medical ethics is undergoing tremendous changes, and the phenomenon of moral imbalance, moral anomie and moral anomie caused by medical staff has become the focus of social attention. In view of these problems, this paper analyzes the basic reasons, focusing on strengthening the construction of medical ethics from the aspects of strengthening publicity and education, strengthening professional awareness, strengthening professional awareness and strengthening their own quality, and puts forward relevant suggestions and countermeasures. Keywords: market economy; Evolution of medical ethics; The construction of medical ethics and the socialist market economic system will inevitably bring profound changes to all aspects of society. The management system and operation mechanism of the hospital are changing, and so are the ideas, values and moral standards of medical staff. The traditional concept of medical ethics is undergoing tremendous changes, and the phenomena such as moral imbalance, moral anomie and moral disorder caused by medical staff have become the focus of social attention. 1 the evolution of medical ethics the evolution of medical ethics I understand refers to the process of the gain and loss, change and change of the meaning of medical personnel in the process of medical service. Its performance is as follows. 1. 1 benefit-driven, medical ethics imbalance With the continuous improvement of people's material living conditions, traditional medical ethics have changed. Driven by interests, some medical staff's views on right and wrong, advantages and disadvantages, and respect and inferiority have also changed. The purpose of hospital service is to reduce diseases and save lives, not just to make profits. However, under the condition of market economy, hospitals become the main body of medical and health services that are convenient for users to operate independently, and both social and economic benefits should be taken into account. If it is not handled properly, it will inevitably lead to the phenomenon of forgetting profits and the imbalance of medical ethics. Starting from their own interests, medical staff repeatedly check the problems of arbitrary charges, accepting red envelopes, kickbacks, prescribing, etc., which disturbs medical order and corrupts medical ethics. 1.2 value orientation, medical ethics is out of order. While the state gives differential subsidies to hospitals, it also marketizes hospital materials. The rise and fall of prices have changed the relationship between supply and demand in the market. When personal interests conflict with collective interests, affected by the unhealthy social atmosphere of market economy system, individual medical personnel may seek immoral compensation and pursue economic interests when their interests are not realized through proper channels. Doctors provide medical services that exceed the actual needs of patients, including replacing simple and convenient applicable inspection techniques with expensive and sophisticated technologies; In the treatment, high-grade drugs are used instead of applicable ordinary drugs; Replace ordinary and safe technical materials with advanced and expensive technical materials. Selling some health care drugs and nutrients to patients has increased the burden of patients' medical expenses and seriously damaged the vital interests of the people and the image of the medical industry [1]. 1.3 Conflict of interests and imbalance of medical ethics With the establishment and continuous improvement of the market economic system, the construction and development of hospitals have changed from dependence to management service. While considering social benefits, hospitals attach great importance to economic benefits. However, the value of medical services cannot be directly measured by money. For patients, hospitals not only have the morality of saving lives, but also bear the burden of increasing hospital operating costs. In the case of insufficient government compensation, the two will inevitably collide in the specific implementation. 2 Rebuilding medical ethics as an endogenous resource for hospital development, medical ethics is one of the important factors to ensure the hospital to be invincible in the competition [2]. Therefore, to strengthen the professional ethics education of medical workers, we should first start with socialist medical ethics education and vocational education, and guide medical workers to establish a correct view of medical ethics and utility in the wave of market economy. 2. 1 people-oriented, do a good job in medical ethics education (1), do a good job in ideals and beliefs education. This is the core of ideological and moral construction, and also the core of medical ethics construction. It is necessary to educate employees to correctly treat the difficulties, interests, adjustments and some problems under the conditions of market economy, strengthen their determination to serve patients wholeheartedly and contribute to the survival and development of hospitals. (2) Educate employees on "Three Views". That is, to educate employees with new outlook on life, values and world outlook, so that employees can correctly treat the relationship between material interests, individuals, collectives and the state, and integrate personal interests into collective interests through education. (3) Educate employees to serve patients wholeheartedly. Educate employees to establish the concept that patients are the "customers" of the hospital, and that patients are the food and clothing parents of hospital employees, correctly understand the relationship between medical staff and patients, and educate employees to always put themselves in their shoes and put the interests of patients first. 2.2 Enhance employment awareness, adhere to socialist medical ethics is to heal the wounded and rescue the dying, prevent and treat diseases, and implement revolutionary humanitarianism; Serve the people's physical and mental health wholeheartedly. This requires the majority of medical staff to treat patients with a high sense of responsibility, treat patients with noble medical ethics, do a good job in medical services with quality services, promote patients' early recovery and improve human health. Therefore, we must combine the reality of market economy, build a brand-new socialist medical ethics system, establish and improve corresponding rules and regulations in combination with medical ethics education, formulate and introduce various regulatory measures, and get to the point of all kinds of drawbacks, so as to enhance the effectiveness of medical ethics education and ensure its further development. 2.3 Strengthening professional awareness to save lives is different from commercial activities. After all, medical staff serve the society. In today's "patient-centered" society, the professionalism of medical staff has more special social significance than that of ordinary practitioners. However, a small number of medical staff are affected by various medical modes such as contract responsibility system, in-hospital outpatient service and expert outpatient service, and they are not satisfied with the present situation. They begin to go out of the hospital and are keen on working outside, relaxing their duties and affecting their normal work. Faced with such a situation, we should not only make medical staff truly understand the profound truth of "unemployment and lack of professionalism" through ideological education, but also boldly adopt scientific management methods to make "unemployment and lack of professionalism" reasonably reflected among medical staff, thus enhancing the seriousness of vocational education and making everyone realize that conventional ideological education is neither empty preaching nor "empty check". 2.4 Strengthen their own quality In real life, the utilitarian thinking of medical staff has its rationality, but utilitarian thinking cannot be the dominant thinking of medical ethics. Once utilitarian thoughts dominate, medical staff will be mercenary, and their behavior will inevitably run counter to good medical ethics, endangering society and causing endless future troubles. If we can correctly guide the medical staff's consciousness of medical ethics and utility in time, practitioners can correctly grasp the relationship between medical ethics and utility in practical work, standardize their thoughts and behaviors with good medical ethics, and make continuous progress with healthy utilitarian thoughts. In this way, when medical staff meet the conflict between utilitarian consciousness and professional ethics, utilitarian thought will consciously obey humanitarian thought, and personal interests will unconditionally obey the interests of patients. Therefore, with "patient-centered" as the goal, excellent business and skilled technology, their own service consciousness will be fully reflected in the actual work of medical staff. Under the condition of market economy, medical ethics education must emphasize the following aspects: (1) The core of medical ethics construction must closely focus on the purpose of serving the people, so that hospital work can truly implement the "three things" (all for patients, all for convenience and all for patients). Only by making cadres and workers establish the idea of high-quality service and medical treatment and the noble quality of loving their posts and dedication can the "four services" (strengthening service consciousness, correcting service concept, improving service attitude and improving service quality) be implemented. (2) To cultivate and strengthen the sense of responsibility as a breakthrough in the construction of medical ethics. Responsibility is the most basic standard and value measure of medical ethics evaluation. Only people with a strong sense of responsibility will be highly responsible for patients, work, hospitals and society. Responsibility is the support point of medical staff's professional ethics. (3) We must establish and improve the medical ethics system. The construction of medical ethics is fundamentally a medical ethics management problem. The so-called medical ethics management is to supervise, inspect and guide medical ethics according to the established medical ethics norms. While adhering to positive education, we should constantly strengthen the restraint mechanism, do a good job in building professional ethics, and adhere to various supervision systems. Every medical staff should establish medical ethics files and conduct regular assessment. Hire foreign social supervisors, further strengthen the domestic medical ethics assessment, insist on holding regular doctor-patient forums, issue satisfaction cards to patients inside and outside the hospital, and follow up the discharged patients. Strictly investigate and punish those who violate professional ethics, and give rewards and punishments simultaneously, so as to implement the construction of medical ethics and greatly improve the overall work level of medical ethics construction in hospitals.
