The association between surgeon subspecialty training and postoperative outcomes following surgery for pelvic organ prolapse.

BACKGROUND

Symptomatic pelvic organ prolapse is common and affects 25% to 35% of women worldwide. As this growing patient need is being met by surgeons from diverse training backgrounds, it is important to both characterize the differences in surgeon practice patterns and examine postoperative outcomes to ensure optimal patient care.

OBJECTIVE

To determine the association between surgeon specialty and postoperative outcomes following surgery for pelvic organ prolapse.

STUDY DESIGN

This was a retrospective analysis using the American College of Surgeons National Surgical Quality Improvement Program Gynecologic reconstructive surgery targeted database between 2014 and 2018. Pelvic organ prolapse surgeries were identified using Current Procedural Terminology codes, and surgical cases performed by urogynecologists or obstetrician-gynecologists were included for analysis. The primary outcome was any 30-day postoperative complication following prolapse surgery. The secondary outcomes were any major or minor postoperative complications, genitourinary complications, reoperation, or readmission within 30-days following surgery. Descriptive statistics were used to characterize the cohort, and pairwise analyses were used to describe the differences between the cases performed by the surgeon specialties. Multivariable logistic regression was used to control for potential confounders.

RESULTS

A total of 3358 women underwent prolapse surgery-68% performed by urogynecologists and 32% by obstetrician-gynecologists. The 30-day postoperative complication rate was higher for surgeries performed by obstetrician-gynecologists than for surgeries performed by urogynecologists (10.7% vs 7.0%, respectively; P<.001). There was no difference in the readmission rates between the 2 groups (2.1% vs 2.0%; P=1.000). However, the reoperation rates were higher for surgeries performed by obstetrician-gynecologists (1.8% vs 1.0%; P=.040). In a multivariable logistic regression model controlling for age, body mass index, American Society of Anesthesiology class, smoking, and type of concomitant surgery (hysterectomy, apical suspension, other prolapse surgery, obliterative procedure, or sling), prolapse surgery performed by a urogynecologist remained associated with nearly 40% lower odds of any 30-day postoperative complication (adjusted odds ratio, 0.62; 95% confidence interval, 0.48-0.80).

CONCLUSION

Prolapse surgery performed by a urogynecologist is associated with lower odds of any 30-day postoperative complication than that performed by an obstetrician-gynecologist.
