The Impact of Nurse Workforce Levels on Patient Outcomes in the UK Hospitals: A Systematic Review
Abstract
Background, aim, methodology, findings and conclusions from this systematic review.
This systematic review examines how nurse staffing levels influence patient outcomes in UK hospitals, with particular attention to the effects of workload on care quality, patient safety and the nursing workforce.
To evaluate relationships among nurse-to-patient ratios, workload pressures, human factors and patient outcomes, while identifying potential approaches for improving staffing efficiency and service quality.
A systematic review was undertaken using the PRISMA framework. Searches included PubMed, CINAHL, Embase and the Cochrane Library. Eligible studies focused on UK hospitals and provided empirical evidence linking nurse staffing with patient outcomes. The Critical Appraisal Skills Programme (CASP) framework was used to assess methodological quality.
Fourteen studies were included in the final review. Across the evidence base, higher nursing workloads were associated with poorer safety and workforce outcomes, including medication errors, mortality, fatigue and burnout. Improved staffing ratios and human-factors approaches emerged as potential strategies for strengthening care delivery.
The review links nurse workforce planning with sustainable healthcare delivery and Sustainable Development Goal 3. The findings support greater attention to staffing, workflow, work environments and the broader systems in which nursing care is delivered.
Improving nurse-to-patient ratios, integrating human-factors principles and supporting sustainable and ethical workforce management may enhance patient safety, care quality and nurse well-being across UK hospitals.

PRISMA Systematic Review
The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. Electronic searches included PubMed, CINAHL, Embase and the Cochrane Library, with eligibility focused on empirical evidence concerning nurse staffing and patient outcomes in UK hospitals.
CASP Assessment
The Critical Appraisal Skills Programme (CASP) checklist was used to assess the quality, relevance and methodological rigour of included studies. The review also used the Systems Engineering Initiative for Patient Safety (SEIPS) model to frame relationships among staffing, workflow, work environments and patient outcomes.
Study Selection
The database searches identified 1,960 records. After duplicate removal, 1,065 records remained. Following screening and eligibility assessment, 14 studies met the final inclusion criteria for the systematic review.
