[Importance of qualitative research for nursing and nursing science].

Qualitative research has an important place in nursing science and is becoming increasingly recognized. Qualitative research in nursing mainly deals with the lived experiences of patients and nurses. In the field of chronic illness, qualitative research has brought to the open some of the processes chronically ill patients undergo and what it means living with chronic illness. In addition, new insights were gained about the processes involved in receiving and in giving care. Qualitative research about chronic illness provided nurses with understanding of the lived experience of patients. This understanding is essential for good nursing care. However, qualitative research is not the only method and for some aspects of nursing not the adequate one. Qualitative and quantitative research are complementary.
