The impact of recent power morcellator risk information on inpatient surgery and patient outcomes.

Aim: We examine the impact of the new risk information about a surgical device on surgery and patient outcomes for hysterectomy in the inpatient setting.

Methods

We utilize a difference-in-differences approach to assess the impact of new risk information on patient outcomes in the inpatient setting between 2009 and 2014. The inpatient data come from a nationally representative sample of hospitalizations in the USA. We use the likelihood of laparoscopic surgery, measures of resource use and surgical complications as outcome variables.

Results

We estimate a three-percentage point decrease in the likelihood of receiving laparoscopic hysterectomy, a one-percentage point increase in the likelihood of experiencing a surgical complication and no impact on resource use, relative to pre-existing means.

Conclusion

Our findings show that there was movement away from laparoscopic surgery in the months following the dissemination of new risk information. These changes had limited effect on patient outcomes.
