BACKGROUND:

Quantifying nurses' perceptions of workload burden when managing critically ill patients is essential for designing interventions to ease nurses' workday.

OBJECTIVES:

To explore pediatric intensive care unit (PICU) nurses' perceptions of their workload when caring for critically ill patients and managing protocolized therapies.

METHODS:

This study was embedded in a multicenter randomized clinical trial where participants were assigned to receive either lower-target or higher-target glucose control. Nurses from 35 participating PICUs completed a baseline survey containing questions about their perceptions of PICU workload in general. They completed an intervention survey after caring for a study patient. Two workload measurement instruments, the Subjective Workload Assessment Technique (SWAT) and the National Aeronautics and Space Administration-Task Load Index (NASA-TLX), were embedded in these surveys.

RESULTS:

Baseline surveys were completed by 1476 PICU nurses, predominantly female with a bachelor's degree and a median (interquartile range) of 6 (3-11) years of nursing experience and 4 (2-9) years of PICU experience. Most nurses (65%) rated time burden as the most important component of their workload, followed by cognitive (22%) or psychological stress (13%) burden. Work performance was selected most often as contributing to workload, followed by cognitive demand, time pressure, effort, and physical demand. Intervention surveys were completed by 73% of enrolled participants (505 of 693). Nurses managing the lower glucose target group reported higher levels of workload burden as measured by the SWAT (P = .002) and NASA-TLX (P < .001).

CONCLUSIONS:

This study describes the workload burden perceived by PICU nurses when managing critically ill patients in general and when managing protocolized therapies.
