Highly educated and skilled nursing care is critical to improving patient outcomes in general and in specialties like neurocritical care. Nursing interventions reflect nursing knowledge, critical thinking, and decision-making and is generally rooted in the nursing process. Nursing interventions are also a key focus of research to better understand how nursing care influences patient outcomes. This review describes the literature regarding nursing interventions in key neurocritical diagnoses and contextualizes it within the broader discussion about the nursing process and nursing interventions research. Publications about nursing interventions in neurocritical care emphasize key themes, including managing neurophysiologic parameters, providing psychosocial support, managing the environmental milieu, and interventions to prevent complications. Further study of how to best support nurses in collecting and interpreting data to form nursing interventions is needed, as is understanding the benefits and limitations of the nursing process in low- and middle-income countries.
