Task: Answer Verification
Input (English): Question: Does one size fit all : the influence of age at surgery on outcomes following Norwood operation?
Answer: In contrast to other institutional series, infants at our center undergoing Norwood operation at an earlier age have worse outcomes. Adoption of published practice patterns could lead to different local outcomes because of intangible center-specific effects, underscoring the principle that results from one institution may not be generalizable to others. Targeted center-specific internal review, if possible, should precede externally recommended changes in practice.
Output (English): no
