Comparing Post-operative Opioid Consumption before and after a Patient-Controlled Analgesia Shortage: A Re-evaluation of Safety and Effectiveness.

This retrospective cohort study aimed to compare post-surgical opioid consumption before and after a PCA (patient-controlled analgesia) shortage. The study evaluated patients who received PCA nurse-administered opioid analgesia (non-PCA). Two hundred and twenty-four patients ≥18 years who were initiated on analgesia within 24 h of surgery were included.
