Examining the impact of postoperative opioid use on length of hospital stay following radical cystectomy.

INTRODUCTION

Radical cystectomy (RC) is associated with high rates of morbidity, prolonged hospital stay, and increased opioid use for postoperative pain management; however, the relationship between postoperative opioid use and length of stay (LOS ) remains uncharacterized. This study serves to investigate the association between postoperative opioid use and length of hospital stay after RC. The relationship between patient and surgical factors on LOS was also characterized.

METHODS

We retrospectively reviewed all patients between 2009 and 2019 who underwent RC at our institution. Patient and perioperative variables were analyzed to determine the relationship between postoperative opioid use and LOS using multivariable linear regression analysis.

RESULTS

We identified 240 patients for study inclusion with a median age of 70.0 years. Median LOS was 10.0 days, with median daily mg morphine equivalent use of 57.5 for patients. Daily mg morphine equivalent use was significantly associated with an increased LOS, as were previous pelvic radiation, postoperative ileus, and higher Clavien-Dindo grade complication during admission (all p<0.05). Median LOS increased by one day for each increase of 13.2 daily mg morphine equivalents received.

CONCLUSIONS

Increased daily opioid use was associated with increased length of hospital stay after RC. Non-opioid-based pain management approaches may be effective in reducing LOS after RC.
