AI Article Synopsis

  • The study aimed to identify factors that influence the duration of aortic valve replacement surgeries, focusing on hospital type, location, case volume, and surgery timing.
  • Data from the National Anesthesia Clinical Outcomes Registry was analyzed, revealing an average surgery duration of 360.8 minutes, with university hospitals showing significantly longer case durations.
  • The findings suggest that both the type of hospital and the timing of surgeries play crucial roles in how long these procedures take, highlighting important considerations for future surgical planning.

Article Abstract

Objective: Currently, there are no large-scale studies that compare differences in case duration of aortic valve replacements (AVRs). The primary objective of this study was to determine associations of hospital facility type, geographic location, case volume per year, and time of day with duration of valve replacement surgery.

Design: Retrospective.

Setting: Data from the National Anesthesia Clinical Outcomes Registry.

Participants: National data from university and non-university hospitals.

Interventions: No interventions.

Measurements And Main Results: All AVRs from the National Anesthesia Clinical Outcomes Registry were identified from 2010 to 2014. Mean case duration for all AVRs was 360.8 ± 95.8 minutes and was presented based on facility type (university hospital, large community hospital, medium-sized community hospital, and other); US geographic region; time of day (cases performed after 5 pm and before 7 am v day shift); and case volume per year. A multivariable linear regression model was built to determine the association of various patient, procedural, and facility characteristics with case duration. University hospitals were associated with increased case duration for AVRs (p < 0.0001).

Conclusions: With this large national database, the authors demonstrated that academic hospitals, time of day of the surgery, US region, and case volume per year for a facility are related to the case duration of AVRs.
