The Effect of Shift Length on Nurse Performance and Patient Safety

Abstract

This study investigated the impact of shift duration on nurse performance and patient safety, focusing on comparing 8-hour versus 12–16-hour shifts. Through an anonymous online survey of 150 nurses in Saudi Arabia, the research examined fatigue levels, decision-making abilities, and quality of patient care across different shift lengths. Results revealed that 82.7% of nurses reported diminished decision-making abilities after 16-hour shifts, compared to 38.6% after 12-hour shifts. Nearly 90% of participants indicated they could not provide optimal care during 16-hour shifts, with 67.7% reporting that extended shifts negatively impacted patient care. Common issues included increased fatigue, slower work pace, decreased concentration, and emotional strain. Additionally, 24.4% of nurses admitted to cutting corners during extended shifts, implementing strategies such as clustering patient care and reducing patient interaction. The findings suggest that limiting shift length to 8 hours may enhance nurse performance and patient safety by reducing fatigue-related errors and maintaining higher quality care standards. The study highlights the need for healthcare organizations to implement more sustainable scheduling practices that prioritize both nurse well-being and patient safety.
