Abstract
Background: Intensive care units (ICUs) are complex and fast-paced environments where nurse-to-patient ratios significantly influence patient outcomes. Existing research highlights the relationship between staffing levels and outcomes such as mortality, hospital-acquired infections, length of ICU stays, patient safety incidents, and nurse job satisfaction.
Aim: This systematic review aims to evaluate the impact of nurse-to-patient ratios on patient outcomes and nurse well-being in ICUs, providing evidence to guide staffing policies.
Study design: A systematic review of 20 studies conducted across various locations was undertaken. The review includes retrospective cohort studies, cross-sectional designs, and other methodologies. The studies were analysed to determine the influence of staffing levels on patient and nurse outcomes.
Results: Safe nurse staffing levels were associated with a 14% reduction in hospital mortality, shorter ICU stays, a 20% improvement in infection prevention, and an average ICU stay reduction of 1.5 days. Enhanced patient satisfaction by 18% in units with adequate staffing. Conversely, lower staffing ratios were linked to a 25% increase in adverse events, nurse fatigue, and diminished patient safety outcomes. The findings underscore the necessity of adequate staffing strategies and the adoption of workforce technologies to enhance care quality in ICUs.
Conclusions: This review highlights the critical role of nurse-to-patient ratios in improving patient outcomes and nurse well-being in ICUs. Future research should focus on standardizing methodologies to evaluate staffing strategies and exploring their long-term impacts on both patient and nurse outcomes.
Relevance to clinical practice: These findings emphasize the importance of implementing evidence-based staffing policies and integrating supportive technologies to ensure optimal care delivery and staff satisfaction in ICUs.
期刊介绍：
Nursing in Critical Care is an international peer-reviewed journal covering any aspect of critical care nursing practice, research, education or management. Critical care nursing is defined as the whole spectrum of skills, knowledge and attitudes utilised by practitioners in any setting where adults or children, and their families, are experiencing acute and critical illness. Such settings encompass general and specialist hospitals, and the community. Nursing in Critical Care covers the diverse specialities of critical care nursing including surgery, medicine, cardiac, renal, neurosciences, haematology, obstetrics, accident and emergency, neonatal nursing and paediatrics.
Papers published in the journal normally fall into one of the following categories:
-research reports
-literature reviews
-developments in practice, education or management
-reflections on practice
