Background to the Study
Nurse-to-patient ratios have been a focal point of healthcare policy debates globally for over two decades. Seminal research by Aiken et al. (2014) established a statistically significant association between high nurse workloads and increased patient mortality in European hospitals. In England, the Francis Report (2013) exposed systemic failures at Mid Staffordshire NHS Foundation Trust, many of which were attributable to inadequate nurse staffing.
Despite these findings, no legally mandated minimum nurse-to-patient ratio exists in England, in contrast to Australia (where a 1:4 ratio is law in Victoria) and California (1:5 in acute care). This policy gap creates variability in care quality and places nursing staff under unsustainable pressure.
Research Problem
The persistence of high nurse workloads within the NHS, exacerbated by post-pandemic staffing shortages and a 47,000-vacancy deficit (NHS England, 2023), necessitates an examination of how current staffing levels affect patient safety outcomes. This study focuses specifically on adult acute care wards across three NHS Trusts in the North West of England.
Aims and Objectives
Primary Aim
To examine the relationship between nurse-to-patient ratios and selected patient safety outcomes (30-day mortality, falls, hospital-acquired pressure injuries, and medication errors) in adult acute care wards.
Objectives
1. To critically review existing literature on nurse staffing and patient outcomes in acute care settings.
2. To analyse routinely collected patient safety data from three NHS Trusts across a 12-month period.
3. To explore ward managers’ perceptions of staffing adequacy and its impact on care quality.
4. To make evidence-based recommendations for staffing policy at Trust and national level.
Significance of the Study
This study contributes to the limited UK-specific evidence base on staffing ratios, addressing a critical gap identified in the most recent NHS Long Term Workforce Plan (2023). Findings will be relevant to NHS Trusts, NHS England, the Royal College of Nursing, and policymakers considering mandatory ratio legislation.
Overview of Methodology
A mixed-methods sequential explanatory design will be employed. Phase 1 involves secondary analysis of patient safety incident data and staffing records. Phase 2 uses semi-structured interviews with ward managers to contextualise quantitative findings. Ethical approval will be sought from the Health Research Authority (HRA).
Structure of the Dissertation
Chapter 2 presents a systematic review of literature on nurse staffing and patient outcomes. Chapter 3 details the methodology and ethical considerations. Chapter 4 presents quantitative and qualitative findings. Chapter 5 discusses results in relation to existing theory and makes practice recommendations.
