This authors of this column explore the use of nursing theory in Poland. A quasi-experimental pretest-posttest study was conducted to explore what, if any nursing theories were used by nurses in Poland, and if an education program on nursing theory increased the use of nursing theory. The study found that while there were discrepancies between the nurses' theoretical knowledge base and their use of these theories in practice, there is evidence of the use of the ideas and theory of Nightingale, Orem, and Henderson in nursing practice in Poland.
