Despite no difference in surgical ligation rate, infants in era 2 had ligation later (median 24 vs. 8 days, p\u2009&lt;\u20090.0001). There was no difference in clinical outcomes between eras, while number of ECHOs per patient was the only resource measure that increased in era 2 (median 3 vs. 2 ECHOs, p\u2009=\u20090.003).<\/jats:p><jats:p>\n            Conclusion\u2003In an era of more conservative PDA management, no increase in adverse clinical outcomes or significant change in resource utilization was found.
