The effectiveness of nurse-initiated interventions in the Emergency Department: A systematic review

Nurse-initiated interventions potentially provide an opportunity for earlier response for time sensitive presentations to the Emergency Department, and may improve time-to-treatment, symptomatic relief and patient flow through the department.

To determine the effectiveness of nurse-initiated interventions on patient outcomes in the Emergency Department.

The review followed the JBI methodology for reviews of quantitative evidence. Each study was assessed by two independent reviewers and data were extracted from included papers using standardized data extraction tools. Outcomes of interest included time-to-treatment, relief of acute symptoms, waiting times and admission rates.

Twenty-six studies were included in the final review, with a total of 9144 participants. Nine were randomized control trials, 17 had a quasi-experimental design. Twelve of the studies involved pediatric patients only and 14 included adult patients only. Interventions, protocols and outcomes were heterogeneous across studies. Overall, nurse-initiated interventions were effective in reducing time-to-analgesia, time-to-treatment for acute respiratory distress as well as improved pain relief and decreased admission rates.

To achieve early intervention and timely relief of acute symptoms, nurses should seek to consistently implement nurse-initiated interventions into their care of patients in the Emergency Department. Several findings are made to inform practice, however future high-quality research with locally specific strategies is required to improve certainty and quality of findings.
