Clinical Trial Summary

This study investigates the association of preoperative anticholinergic medication exposure with healthcare resource utilization in a population-based sample of older patients enrolled in a universal pharmacare program

Description:

Multilevel multivariable regression analysis will be used to investigate the adjusted association between preoperative Anticholinergic Risk Scale and postoperative healthcare resource utilization. Sensitivity analyses will be used to evaluate the robustness of the primary analysis.
