A Systematic Review and Meta-Analysis on the Impact of Multidisciplinary Approaches in Critical Care on Patient Survival and Recovery Rates

Abstract

This meta-analysis systematically evaluates the effectiveness of nursing and intensive care strategies in improving clinical outcomes for critically ill patients. Drawing from high-quality studies conducted between 2010 and 2024 across diverse healthcare settings, the analysis incorporates data from over 14,500 ICU patients. Key nursing interventions examined include optimal nurse-to-patient ratios, evidence-based protocols, early warning systems, and multidisciplinary team collaboration. Results indicate a 19% reduction in ICU mortality, a 24% decrease in hospital-acquired infections, a 1.53-day reduction in ICU length of stay, and a 27% decline in adverse events. These findings emphasise the pivotal role of structured, nurse-led interventions in enhancing patient safety, reducing complications, and promoting faster recovery. The study underscores the need for adequate staffing, interprofessional collaboration, and protocol standardisation as vital components of quality ICU care. Implications for healthcare policy and clinical practice are discussed, along with recommendations for future research in low-resource and post-discharge care settings
