Processes, outcomes and evaluation: challenges to practice development in gerontological nursing.

When aligned to participants' needs, evaluation may be used to enhance practice developers' work. Process evaluation enables practice developers to evaluate as they develop; making evaluation an integral part of practice development rather than an 'add on task'. It is contended that beginning practice developers can discharge their need to evaluate their work through the practice development techniques of critical reflection, dialogue and action learning. These form the basis of iterative and formative evaluation activity. However other types of evaluation are important for different audiences in practice development. Consideration of the purpose and utility of evaluation in a range of contexts in which gerontological nursing occurs, brings some clarity regarding the scope of the evaluation required to sustain practice development initiatives. In addition, it helps to clarify the nature of the evaluation required to provide evidence of patient-centred outcomes from developments in the practice of gerontological nursing.
