Task Switching Is the Burnout Mechanism Nobody Measures
It’s not the volume of work alone. It’s the constant interruption. A nurse starts reviewing a patient chart, gets pulled to answer a phone call about a scheduling question, returns to the chart, gets asked about an insurance issue, returns to the chart again. Each switch carries a cognitive cost. Over a full shift, that cost adds up to exhaustion, errors, and resentment.
Burnout drives turnover. Turnover is the real expense. Replacing a registered nurse costs an organization between $40,000 and $100,000 depending on specialty and market. That’s recruiting, onboarding, training, and the productivity gap while the new hire ramps up. Meanwhile, the remaining staff absorbs the extra workload, which accelerates their burnout. It’s a cycle that feeds itself.
