Abstract
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 vs. 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. The primary outcome was opioid consumption in average daily oral morphine milliequivalents (MME). The results showed that patients in the PCA group had increased MME consumption (162 ± 100.4 vs. 70.7 ± 52.8, p < 0.01), increased length of hospital stay (4.2 vs. 3.2 days, p < 0.01), and increased frequency of nausea (33 vs. 17.9%, p < 0.01). After controlling for confounding factors, the PCA group utilized significantly more opioids (84.6 MME/day, p < 0.01) than the non-PCA group. There was no difference in pain AUC/T (0.19 ± 0.07 vs. 0.21 ± 0.08, p = 0.07) and average opioid prescribing upon discharge (150 [77.5-360] vs. 90 [77.5-400], p = 0.64) between the PCA group and non-PCA group, respectively. These results question the routine use of PCA in post-operative patients due to the increased risk of opioid consumption, longer length of hospital stay, and higher incidence of nausea.
