In a theoretical part of the paper, the main focus is on characteristics and terminology of premature babies, breastfeeding, classification systems NANDA International, NIC and NOC, about also management which is an integral part of nursing process. Both quantitative and qualitative researches were used to obtain and process all data. In quantitative method was used a method of document was used, content analysis and quasiexperiment. Results of quantitative research were processed in SPSS software, version 16.0 Statistical Package for Social Sciences, where a method of nonparametric correlation was used. A pen and paper interview with open questions was used in qualitative section of research. Before the research itself, a deputy of nursing care in hospital Nemocnice České Budějovice, a.s. was addressed. The research was implemented between February 2013 and April 2013. First research cluster consisted of nine mothers and eleven premature babies in which two of the mothers had twins. Basic criteria for entering the research, was a necessary hospitalization of both the mother and the child, which the hospital Nemocnice České Budějovice, a. s. offers. The major criterion was an initiated lactation. Second research sample consisted of nurses working at Stanice intermediární péče II. (IMP II ? rooming) of Nemocnice České Budějovice a. s. First of goals was to create files from classification systems NANDA International, NIC, NOC for development and support of breastfeeding for premature babies. The main goal of this work was to create a comprehensive documentation mediated by classification systems NANDA International, NIC, NOC for growth and support of premature babies. The theoretical content of the paper itself was used to create documentation and its usage in praxis. It was not mentioned to create new, but to apply already well known, verified and proven classification systems, which can make not only breastfeeding, but also the daily routine of a nurse more efficient. The suggested documentation solves the issues of breastfeeding of premature babies to help mothers, but also to increase a professional prestige of nurses. Documentation was compiled to include all the necessary information needed for the correct nursing process method. Significant part of documentation is a preliminary case history of mother and child, which offered valuable information. Further attribute were nursing diagnoses dealing with breastfeeding issues of premature babies and intervention realized during hospitalization. It was necessary to address each entry concerned with premature babies individually, based on complex evaluation of overall condition. Many pieces of knowledge from specialized literature on the topic of premature babies and personal experience of doc. PhDr. Mária Bolendovičová, PhD. were used to create the documentation. Second aim of the study was verification of selected specimens on clinical praxis. Third aim was to monitor nurses in Stanice intermediární péče II. (IMP II ? rooming) and their attitude to usage of classification systems NANDA International, NIC and NOC. Based on interviews with nurses it was proven that nurses have better knowledge of NANDA Internationals classification systems than knowledge of NIC and NOC. Final documentation was tested in the perspective of medical staff and its exploitability in clinical praxis. It was found that nurses sense the classification systems NANDA International, NIC and NOC as an appropriate tool, but only with more staff present to work on station. From statements of nurses was clear that establishing a diagnoses is a responsibility of each nurse taking part in nursing process.
