The health sector is an area where door guards are often used. But what exactly are they doing? And what sectors of the industry do they work in? In this article, we define the term Gatekeeper, their role in health insurance and long-term care, as well as some of the criticisms of them. One of the so-called pre-products of using a medical doorman is to keep health costs low by avoiding unnecessary testing and interventions, by requiring a doctor to provide secondary care and care for help. But a doorman can also relate to a person. In this case, in the area of health insurance, a doorman describes the person responsible for treating a patient. Anyone who receives health insurance through a health care plan, particularly a health care organization or an HMO plan, has a door guard assigned to them or are authorized to choose one. The Gatekeeping process has expanded from the traditional act of deciding which news is the best news, but information in general. According to Marcelo Thomas, there are actors called mediators involved in the information architecture with which we are in contact. You decide the structure and content of our information.
 These decisions make these intermediaries technological goalkeepers. Providing information to a member of the organization and those outside the organization is not so much about the results of programming media as it is about a practical approach to ease of use. An example of this role would be a content manager for a company`s knowledge base. All reference items and materials are designed and updated by these managers. Although they may work in supervisory teams, the fact remains that decisions will be made as to what content will be available on the site and how it will be displayed. A doorman refers to requirements that must be met before a person is eligible for a long-term care plan or a person who supervises treatment of the patient through a health care organization (HMO). Some of the disadvantages of using a medical gatekeeper, on the other hand, have been reported that physicians feel more like administrators as care providers acting, as well as concerns about primary care providers refusing or limiting referrals to keep their patient load low, patients feel like they are limited in their choice of health.
