An innovative on-call system for paediatric residency programs: The alternate night float

BACKGROUND: Night-float systems, in which residents work consecutive nights, have been increasingly adopted in paediatric programs, but may be detrimental to residents' sleep and mood. OBJECTIVE: To describe the self-reported impact of a novel system consisting of two consecutive weeks of 16 h overnight shifts every second day that was piloted at the Children's Hospital of Eastern Ontario (Ottawa, Ontario). METHODS: A survey of 28 senior paediatric residents examined their experience with the alternate night-float system in three domains (patient care, resident professional development and wellbeing) and their comparison of the system with the traditional overnight on-call system. RESULTS: Twenty-six of 28 residents responded. Nearly all (96%) felt familiar with important details of inpatients and that handover was effective (92%). Results were mixed for professional development, with concerns about the quality of supervisors' feedback and perceived difficulty in attending daytime teaching. All residents believed that the night-float system provided a better learning experience compared with the traditional system. Less than 35% considered fatigue to be a notable problem, although 20% increased use of sleep aids or stimulants beyond their typical use. Ninety-six percent believed their workload was appropriate. All residents felt equally or less fatigued under the night-float system compared with the traditional system. Ninety-six percent recommended that the night-float model continue as the on-call system. CONCLUSIONS: This novel night-float system is an alternative method of providing paediatric inpatient night coverage because it meets duty hour regulations and has strong resident approval. Studies to examine its impact on residents and patient care in comparison with other systems are warranted.
