Abstract
BACKGROUND: Having entered the US market relatively recently, the perioperative role of intravenous acetaminophen (ivAPAP) remains to be established for several surgeries. Using national data, we therefore assessed current utilization and whether it reduces inpatient opioid prescription and opioid-related side effects in a procedure with relatively high opioid utilization. METHODS: Patients undergoing a lumbar/lumbosacral spinal fusion (n = 117,269; 2011-2014) were retrospectively identified in a nationwide database and categorized by the amount and timing of ivAPAP administration (1 or >1 dose on postoperative day [POD] 0, 1, or 1+). Multivariable models measured associations between ivAPAP utilization categories and opioid prescription and perioperative complications; odds ratios (or % change) and 95% confidence intervals are reported. RESULTS: Overall, ivAPAP was used in 18.9% (n = 22,208) of cases of which 1 dose on POD 0 was the most common (73.6%; n = 16,335). After covariate adjustment, use of ivAPAP on POD 0 and 1 was associated with minimal changes in opioid prescription, length and cost of hospitalization particularly favoring >1 ivAPAP dose with a modestly (-5.2%, confidence interval, -7.2% to -3.1%; P < .0001) decreased length of stay. Use of ivAPAP did not coincide with a consistent pattern of significantly reduced odds for complications. In comparison, the most commonly used nonopioid analgesic, pregabalin/gabapentin, did demonstrate reduced opioid prescription combined with lower complication risk. CONCLUSIONS: We could not show that perioperative ivAPAP reduces inpatient opioid prescription with subsequent reduced odds for adverse outcomes. It remains to be determined if and under what circumstances ivAPAP has a meaningful clinical role in everyday practice.
