Methods: The inclusion criteria for selected studies included primary research articles published within the last five years, which incorporated various search terms stated below. Both quantitative and qualitative studies were included. The quantitative studies were of experimental, quasi-experimental, cross-sectional, and longitudinal cohort design. The qualitative studies were of phenomenological design. There were 19 primary research articles and one Cochrane review used. Including a Cochrane review was significant to our literature review because it provided us with a strong, evidence-based, systematic review of published healthcare research. Databases used were CINAHL and Ovid. Search terms used were "nursing", "nursing role", "nursing care", "nursing interventions", "microbial", "antibiotic "stewardship", "multi-drug resistance", "infection control", and "patient education".
Results: Though increasing research has been conducted regarding ASPs in recent years, these programs are still relatively new, dating back only about 15 years. Research has shifted from studying “miracle drugs” to studying the increase in antibiotic resistance, related infections, and the roles healthcare providers play in maintaining the health of the public. As previously noted, the gold standard for ASPs is the CDC’s "Core Elements of Hospital Antibiotic Stewardship Programs" which only mentions “nurse” four times (CDC, 2014). The focus while examining the articles obtained for the literature review was identifying similar themes that group members felt targeted ASPs, while simultaneously determining how often "nurse" was mentioned. It was quickly discovered that only 50% of articles included in the table displayed the word "nurse". The thematic analysis revealed the following themes: overprescription, hand hygiene, education, acquisition of knowledge and compilation of available data, and protocol. The results are broken down by theme, and then further ordered by inclusion or exclusion of the nurse. Articles with multiple themes were included in one or more sections.
Conclusion: ASPs are a vital factor in reducing the spread of multi-drug resistant organisms. Multi-drug resistance has become an international phenomenon and a strong threat to the human population. Therefore, it is imperative that ASPs continue to be developed and implemented. According to the IOM, nurses play a vital role on the interdisciplinary team, yet the nurse's role in ASPs has not been explicitly stated. The themes throughout the literature review include the impact that proper assessment or screening has on the overprescription of antibiotics, the importance of the basic yet fundamental tool of hand hygiene in preventing the spread of multi-drug resistant organisms, how education can disseminate previous and upcoming knowledge, and how improved infection protocols can establish new expectations for the entire interdisciplinary team. Each of these initiatives should be clearly stated as a responsibility to be carried out by the nurse. Further research is necessary to provide structured guidelines that explicitly include the role of the nurse in antimicrobial stewardship in preventing multi-drug resistant infections in the hospitalized patient.
