Theoretic interest in the nature of events and event identity is apparent across a wide range of fields. However, this interest has not yet made itself known in nursing. In this paper, it is asserted that nurse theoreticians and researchers should consider the problematic of events and event identity. It is suggested that engagement with these issues is important because the manner in which this component of explanation is integrated into argument has concrete implications for our understanding of healthcare practice. (...) Indeed, refusal to engage with such issues may jeopardize explanatory coherence. (shrink)
