Intensive and Critical Care Nursing Volume 94, June 2026, 104322 Impact of Pre–ICU benzodiazepine and Z–Drug exposure on mortality in critically ill Adults: A nationwide retrospective cohort study: A nationwide retrospective cohort study

This research study investigates whether taking common sleep aids or anti-anxiety medications, specifically benzodiazepines and Z-drugs, prior to entering intensive care affects a patient's chances of survival. By analyzing a massive database of over one million hospital admissions, researchers discovered that individuals who used these substances in the month leading up to their ICU stay faced a significantly higher risk of death at both the 30-day and 90-day marks. The danger was most pronounced for patients using a combination of both drug types, suggesting that these prescriptions serve as a critical warning sign for medical staff. Ultimately, the authors argue that identifying this pre-admission medication history is a vital tool for doctors to better assess patient vulnerability and potentially improve outcomes through careful drug management.
