Impact of Interventional Radiology on Patient Recovery Time: A Statistical Comparison with Traditional Surgery

Abstract

Background: Interventional Radiology (IR) has emerged as a transformative discipline offering minimally invasive alternatives to conventional surgical procedures. The present study investigates the effect of IR on patient recovery time in comparison to Traditional Surgery (TS). Methods: A one-way ANOVA was conducted using data from 200 patients divided equally into two groups. The primary outcome measured was recovery time (in days). Statistical significance and effect sizes were evaluated, alongside assumption checks including Shapiro-Wilk test and Welch’s ANOVA. Results: Patients undergoing Interventional Radiology exhibited a significantly shorter recovery time (M = 8.04 days, SD = 1.91) than those treated with Traditional Surgery (M = 9.79 days, SD = 1.82), F(1,198) = 44.0, p < .001, with a large effect size (η² = 0.182). Normality and variance assumptions were satisfied, confirming the robustness of the analysis. Conclusion: The findings demonstrate that Interventional Radiology significantly reduces patient recovery time compared to Traditional Surgery, supporting its integration as a preferred clinical approach in appropriate cases.
