Abstract
Inadequate nurse staffing remains a critical challenge in tertiary care hospitals, contributing to compromised patient safety, reduced quality of care, increased clinical complications, and increased healthcare costs. Maintaining appropriate nurse-to-patient ratios is essential for ensuring positive patient outcomes and efficient healthcare delivery. This study aimed to analyze the impact of nurse staffing levels on patient safety, quality of care, and clinical outcomes in tertiary care hospitals. A quantitative cross-sectional research design was adopted, involving registered nurses and hospital administrators from selected tertiary care hospitals. Data were collected using a structured questionnaire to assess nurse staffing levels, patient safety indicators, quality of care, and clinical outcomes. Descriptive statistics, Pearson correlation, and multiple regression analyses were employed to examine the relationships among the study variables. The findings demonstrated that adequate nurse staffing levels were significantly associated with improved patient safety, enhanced quality of care, lower rates of medication errors and hospital-acquired infections, shorter lengths of hospital stay, and higher patient satisfaction. In contrast, inadequate staffing was linked to increased adverse events, nurse burnout, and poorer clinical outcomes. The study concludes that optimizing nurse staffing is a strategic priority for tertiary care hospitals and healthcare policymakers. Implementing evidence-based staffing policies can improve patient safety, strengthen the quality of healthcare services, enhance clinical outcomes, and support the long-term sustainability and effectiveness of healthcare systems
