[ASSESSMENT OF PATIENT SATISFACTION WITH THE MEDICAL ORGANIZATION AND ITS SERVICES].

The relevance of the problem under study is due to the fact that the medical organization must be aware of the target patient: to know who he is, how and why he wants to receive a particular medical service. All the information received and its analysis will allow us to develop a real scheme of mutually beneficial communication, convenient for each of the parties-the medical organization and the patient, which will allow us to reveal the weaknesses in the work and respond to them in a timely manner. The purpose of the study: to form an assessment of the patient's satisfaction with the medical organization and its services, taking into account the interest, feelings, purpose, arguments and thoughts that appear in the patient from the moment of the first contact with the clinic, with the display of the point of contact in graphic form, in order to minimize all possible obstacles in his route to receiving quality medical services and increasing the economic efficiency of the clinic.

A source of a reference spherical wave based on a single mode optical fiber with a narrowed exit aperture.

A new type of a reference spherical wave source (SWS) based on a single mode optical fiber with a narrowed down up to the submicrometer size exit aperture is proposed. It is intended for the precision point diffraction interferometers as a source of a reference wave. Systematic experimental errors which influence the measurement accuracy of the quality of the wave fronts generated by the SWSs are considered. Experimental data on wave front deformations are given. The combined root-mean-square (rms) wave deformation for a couple of the SWSs measured in a numerical aperture of NA=0.27 reaches the value of rms=0.36 nm that corresponds to rms=0.25 nm of a single SWS or about lambda2500 for the red He-Ne laser.
