When Re-reading Replaced Retrieval: Medication Protocol Errors After Passive Training
A real-world example of Testing effect in action
Context
A 150-bed community hospital rolled out a new electronic health record (EHR) medication-ordering workflow and provided a mandatory two-day training consisting mostly of walkthroughs and detailed manuals. Leadership assumed that staff who 'studied' the procedures would retain the steps because they had attended the sessions and reviewed the documentation. The hospital did not include structured retrieval practice or follow-up quizzes in the rollout plan.
Situation
Nurses and pharmacists completed the training and were given printed reference guides and access to a recorded demo. There were no graded assessments, no low-stakes quizzes, and no scheduled refreshers; supervisors trusted that on-the-job practice would consolidate learning. Within weeks staff reported feeling confident, but managers noticed recurring small mistakes in medication orders and dispensing.
The bias in action
Because training emphasized exposure (re-reading manuals and watching demos) rather than retrieval practice, staff overestimated their ability to recall correct ordering steps under pressure. The 'testing effect'—that active recall strengthens memory more than passive study—was not leveraged, so many clinicians could demonstrate the workflow immediately after training but failed to retrieve the correct steps later. Familiarity from repeated reading created an illusion of mastery, and intermittent on-shift stress exacerbated retrieval failures. Supervisors interpreted early confidence as sufficient learning and delayed follow-up assessments, reinforcing the mistaken belief that repetition of study equals retained competence.
Outcome
Within three months, the hospital experienced an increase in EHR-related medication ordering errors that required pharmacist intervention and order corrections. Management instituted ad-hoc refresher sessions after noticing a pattern, but initial delays exposed patients to preventable risks and increased staff workload. A formal retraining program emphasizing active recall was developed after an internal audit.
