Clinical hospitals are a specific group of hospitals connecting service activities of diagnostic and therapeutic nature, with teaching, scientific and R&D activity. The ways to make better use of their potential are sought in order to improve the functioning of these hospitals. One way is to improve the structural measures, i.e. improving the organizational structure. The lack of regulation in the field of structural solutions in clinical hospitals in Poland prompted the author to analyze the organizational structure of the University Policlinico Agostino Gemelli in Rome (Policlinico Gemelli). The purpose of this article is to present organizational structure of the hospital on the example of the Policlinico Gemelli and an attempt to determine the direction of further improvement and an indication of the conditions for the application of experience of Policlinico Gemelli in hospitals in Poland. Analysis of the organizational structure of the Policlinico Gemelli was carried out based on Internet sources and by participating observation. According to the Aston's concept, assessment of the organizational structure should be made in five dimensions: specialization, configuration, standardization, centralization and formalization. For the aim of this article, two dimensions were evaluated: configuration and centralization. The structure of the Policlinico Gemelli is hybrid and is characterized by a high degree of decentralization. Further improvement of the structure of the Policlinico Gemelli should apply to improving coordination with the University of Sacro Cuore and the Institute Toniolo, forming Foundation of Policlinico Gemelli supervising and controlling this hospital. Clinical hospitals in Poland can benefit from the experience of Policlinico Gemelli primarily in the area connecting the hospital structure with the structure of the university, through the creation of complex structures. Large hospitals in Poland could benefit from the option involving an organizational structure of two separate divisions: clinical division manager and medical division manager. Such a solution would allow for better implementation of specific tasks for clinical hospitals.

Key words: organizational structure, improving the organizational structure, clinical hospital.
