Conclusion

ASD patients who underwent surgical procedures with ASD-SR invasiveness scores of ≥90 had greater odds of experiencing major complications, whereas their odds of minor complications (except for incidental durotomy) were not greater above this threshold. By ASD-SR score quartiles, the largest increase in complications was when ASD-SR score increased from below 90 to ≥90. These results improve the utility of the ASD-SR invasiveness index when counseling patients during the perioperative period and provide a better understanding of the complex relationship between surgical invasiveness and complication risk.
