The authors explore the current state-of-the art of correctional nursing by summarizing the types of interventions employed by nurses, across studies, designed to assist this challenging group of patients. This examination of evidence-based interventions implemented and tested by correctional nurses provides a better understanding of their role and function. Correctional health is a nurse driven system, yet a minimal amount is known about the nurses who practice in these environments or about their contributions to the practice of mental health nursing in correctional environments. An integrative review utilizing PRISMA guidelines examined five databases (Medline/PubMed, PsycInfo, PsychArticles, Sage Criminology, and Academic Search) for peer-reviewed articles that fit selected criteria. Of 324 references identified, 16 studies met criteria. Following assessment of strength of evidence, only eight studies offered scientific proof of the effectiveness of nursing interventions. Nursing interventions implemented in correctional settings targeted incarcerated persons with behavioral and psychological symptoms. Interventions included psycho-education, environmental adaptations, and behavior therapies. The centrality of nurses in correctional health care emphasizes the significance of understanding their role and function in this setting. This integrative review revealed that correctional nurses are actively engaged in providing therapeutic, evidence-based interventions in the health care of incarcerated persons. Of interest, seven of the eight studies focused on incarcerated persons with mental health or substance use issues. Nurse led interventions such as CBT, labyrinth walking, and yoga aim to improve coping and adaptation of incarcerated persons.
