Understanding the Association Between Comprehensive Nursing Care Service Policy and Patient Outcomes

Background: – To reduce the burden of care and prevent health care-associated infections, the comprehensive nursing care services (CNCSs) model was implemented in South Korea. Purpose: – The purpose of this study was to review and synthesize the association between CNCS units and patient outcomes. Methods: – This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement guidelines. Articles published between 2013 and March 2025 were searched. Results: – Online searches yielded 9417 articles; 23 articles were included in the review. Multivariate analyses evaluating the impact of CNCS units on 7 patient outcomes were conducted in 8 studies. Approximately half the relationships between CNCS units and patient outcomes were positive and significant. Conclusion: – Inconclusive relationships between CNCSs and patient outcomes were found. Future studies should investigate the consequences of CNCSs using a longitudinal study design and other covariates to draw a causal relationship.
