Lethal Dose, Blame Passed Down: How a Hospital Protected Its Image at the Expense of Safety
A real-world example of Defensive attribution hypothesis in action
Context
A mid-sized regional hospital had recently rolled out a new electronic medication administration record (eMAR) system. Leadership was under pressure to show improved safety metrics and avoid regulatory scrutiny.
Situation
A patient on the medical ward received a lethal overdose of a high-risk sedative after a nurse selected the wrong drug option in the new eMAR interface. The incident happened three months after rollout and during a busy overnight shift with limited staffing.
The bias in action
Immediately after the event, senior clinicians and administrative leaders emphasized the nurse's failure to double-check the medication, framing the error as an isolated act of incompetence. Discussions and memos highlighted the nurse's training gaps and history of small mistakes, while system factors — confusing dropdown labels, default dosing values in the eMAR, and poor staffing levels — received little attention. By attributing blame to an individual, decision-makers preserved the belief that existing protocols, training programs, and leadership oversight were adequate and that their own professional competence and safety systems were intact.
Outcome
The nurse was suspended and later terminated; the hospital issued a brief statement about individual accountability and made small changes (a reminder email and re-training). No immediate system-wide redesign or independent root-cause analysis was conducted. Six months later the hospital recorded an uptick in near-miss medication events and growing staff turnover; a family filed a malpractice suit that proceeded to mediation.
