Nursing Is that a nurse?
Health managers are getting hotter and hotter, and it's more favorable for nurses to enroll! We all know that the State Council canceled 15 health care related qualifications, including the nurse more favorable public **** dietitian. However, in the context of the vigorous development of China's health industry, health manager has become another popular career suitable for nursing staff, so should nurses participate in it? What kind of career is a health manager? A health manager is a professional who is engaged in monitoring, analyzing, and evaluating health, as well as health consultation, guidance, and health intervention. According to the National Occupational Standards for Health Managers, there are 3 levels of health managers***. It should be noted here that at present, the National Health Planning Commission only carries out vocational qualification appraisal for Level 3 Health Manager. Health manager is mainly engaged in the work content includes: ① collection and management of individual or group health information; ② assessment of individual or group health and disease risk; ③ individual or group health consultation and guidance; ④ development of individual or group health promotion plan; ⑤ individual or group health maintenance; ⑥ individual or group health education and promotion; ⑦ health management technology research and development; ⑧ health management technology research and development. (vii) Research and development of health management technology; (viii) Evaluation of the effectiveness of the application of health management technology. Benefits of nurse certification 1. Nursing needs At present, the nursing service field is gradually expanding from medical institutions to the community and family, and the service content is extending from the clinical treatment of diseases to the management of chronic diseases, geriatric care, long-term care, rehabilitation promotion, etc., which requires a large number of health management manpower to fill in the gaps. In addition, the healthcare reform vigorously develops the service model of "three divisions***one" of large hospital specialists, grassroots general practitioners (family physicians) and health managers, guiding the sinking of high-quality medical resources to the grassroots level, in which health managers are the roles assumed by nurses.2. The need for nurses to engage in multi-practice In recent years, the demand for mass healthcare In recent years, the demand for health care services has become increasingly multi-level and diversified, and the connotation and extension of nursing services have gradually changed, with an increase in the demand for primary health care, health management, geriatric care, chronic disease care, hospice care, and continuity of care for patients after discharge from hospitals for acute illnesses. The rapid development of health service industries, such as medical care integration, social capital medical care, and "Internet+Nursing", has further expanded the field of nursing services, and nursing services have been gradually extended from institutions to communities and families. At the same time, the construction of hierarchical diagnosis and treatment medical service system puts forward new requirements for the primary nursing service capacity.3. The development of the workplace needs of the health industry will make the hospital involved in the vigorous development of the health management, health guidance, health assessment and so on will become one of the direction of the development of hospitals. With the aggravation of our country's aging population and the gradual deepening of health care reform, even if the work in the medical institutions, whether it is the national policy requirements, or economic benefits, health management will become one of the key development direction, but also inevitably become the stage for nurses to show their vocational skills.
