Organizations providing sanatorium and resort treatment often face a shortage of highly qualified health care professionals. Outsourcing of the medical service causes a number of new difficulties and is often impossible. At the request of practical healthcare, the author conducted a search for best practices to solve these problems. It turned out that alternative management models are absent both in open literature sources and among well-known organizations of the sanatorium-resort profile. As a result, the author has developed and implemented a new management model in which the general management of the organization and line staff remain on the customer's staff, and the management of the medical service is transferred to an outsourcer contractor with appropriate personnel and expertise. The advantages of this model are:
1) flexible contract management; 2) cost optimization; 3) elimination of excessive time and money expenses; 4) expansion of competencies; 5) risk minimization; 6) reduction of non-income-generating workspaces. Optimization of about 25 % of the direct costs of managing the medical service, as well as a number of indirect costs, has been achieved. At the same time, it was possible to avoid the problems caused by outsourcing of the medical service. The limitations of the proposed model are revealed: 1) suitable only for organizations with a small medical service; 2) does not provide direct sales of services to customers; 3) does not include research work. Thus, the developed model can be applied in organizations providing sanatorium and resort treatment, taking into account the existing limitations.
