Validation of the Twenty-Four-Hour Threshold for Bladder Repair: Impact on Infection Rates Using the National Trauma...

Area of Science:

• Trauma surgery
• Urology
• Patient outcomes

Background:

• Bladder injuries are a serious concern in trauma care.
• Previous research suggests a link between delayed bladder repair and adverse outcomes.
• The National Trauma Data Bank (NTDB) provides a valuable resource for studying trauma patient management.

Purpose of the Study:

• To validate the association between delayed bladder repair and increased infection rates.
• To compare mortality, infection rates, and hospital length of stay (LOS) between early and delayed bladder repair groups.
• To analyze the impact of timing of bladder repair on patient outcomes using a large trauma database.

Main Methods:

• Retrospective analysis of bladder injury patients from the NTDB (2013-2015).
• Propensity score matching (PSM) to create comparable groups for early (<24h) versus delayed (≥24h) repair.
• Statistical analyses including linear and multivariate logistic regression.

Main Results:

• Delayed bladder repair (≥24h) was associated with significantly higher infection rates (5.4% vs. 1.2%) and longer hospital LOS (17.1 vs. 14.0 days).
• Regression analyses confirmed that delayed repair increased infection risk (OR=3.162) and correlated with longer LOS.
• No significant worsening of outcomes was observed in patients repaired within 24 hours.

Conclusions:

• Delaying bladder repair beyond 24 hours significantly elevates the risk of post-operative infections and prolongs hospital stays.
• Timely diagnosis and surgical intervention are critical for improving outcomes in patients with bladder injuries.
• Adherence to early repair protocols is essential for minimizing complications and optimizing patient recovery.
