A hospital-wide before-and-after change cannot isolate the effect of one substitute drug.
Study findings
After a lemborexant-based formulary was introduced, the hospital reported lower diazepam-equivalent prescribing, fewer monthly delirium cases and a shorter median stay. Previously used hypnotic orders in 104 pathways and prescription sets were changed. More than twelve thousand admissions were assessed in each period.
What limits the conclusion
There was no concurrent randomized control hospital. Case mix, practice and documentation could change over time. The intervention involved default orders and multidisciplinary processes as well as particular medicines.
Implications for case review
Describe the system change when attributing outcomes. Lower prescription totals do not prove that every patient’s exposure or risk decreased. For individual review, identify actual administration and subsequent observations instead of treating a formulary’s aggregate association as proof of a particular drug’s benefit.
