Preoperative Opioid Use and its Association with Postoperative Complications.

BACKGROUND

The negative impact of opioid use in the U.S. has led providers to seek alternative methods for pain control. More specifically, preoperative opioid usage has been demonstrated to adversely affect patients and clinical outcomes. This study aims to assess the extent of the relationship between preoperative opioid use on postoperative outcomes across surgical disciplines using statewide population databases.

METHODS

The study used the Utah All Payers Claims Database and Utah Population Database to identify a cohort of adult patients who underwent a single surgery between 2013-2016 and had continuous insurance enrollment. Preoperative opioid prescription within one year prior to the index surgery was the independent variable, while complications and hospital admissions one year following the index surgery were the primary outcomes.

RESULTS

Our model of 18,647 patients found that the odds of any complication with preoperative opioid use was 1.28. Depression (OR 1.17) and drug misuse (OR 1.41) were also associated with a higher risk of postoperative complications. Rates of hospital readmission in the preoperative opioid use group compared to the opioid naïve group were increased (19.43% vs. 12.44%, P < 0.01).

CONCLUSION

The data can be used to guide patient-physician conversations and better inform prescribing habits perioperatively.
