From simplicity to complexity: developing a model of practical skill performance in nursing.

The purpose of this article is to present and discuss a new model of practical skill performance in nursing. The model is conceptualized as having five components: substance and sequence; accuracy; fluency; integration; and caring conduct. The model challenges the truism of 'simple' nursing procedures. It is argued that performance of practical skills in nursing is characterized by complexity on many levels. Complexity lies within and between the components of the performance model and in the interaction between the nurse and the clinical context where practical nursing actions are performed. These complexities are described. Examples that illustrate the complex and reciprocal nature of these components are drawn from an empirical study of graduate nurses' development of practical skill in surgical hospital units. Implications of the model for education, practice and research are discussed.
