Abstract

Introduction: The purpose of this study was to determine whether time from hospital admission to surgery is associated with inpatient complications and mortality for geriatric patients undergoing surgical treatment of acetabular fractures.

Methods: This was a retrospective cohort study using the National Trauma Data Bank from 2016 to 2018 of patients presenting to level I through IV trauma centers in the United States. All patients aged 60 years or older with acetabular fractures requiring surgical treatment were included. The main outcome measurements were inpatient mortality and complication rates.

Results: There were 6,036 patients who met inclusion criteria. The median age was 69 years (interquartile range 64-76 years). The odds of a complication increased by 7% for each additional day between hospital admission and surgery (multivariable regression OR 1.07, 95% CI = 1.04 to 1.10; P < 0.001). Complications were also associated with patient age (OR 1.05, 95% CI = 1.03 to 1.06; P < 0.001) and mCCI ≥ 5 (OR 2.52, 95% CI = 1.4 to 4.2; P = 0.001). Inpatient mortality was not associated with time to surgery (OR 0.97, 95% CI = 0.92 to 1.02; P = 0.30), but was associated with patient age (OR 1.07, 95% CI = 1.05 to 1.10; P < 0.001; P < 0.001) and mCCI ≥ 5 (OR 4.62, 95% CI = 2.31 to 8.50; P < 0.001).

Discussion: In this database study, time from hospital admission to surgery was associated with a notable increase in inpatient complications but not inpatient mortality after adjusting for potentially confounding variables while age and mCCI were associated with both mortality and complications. Additional research is needed to determine the relationship between time to surgery with longer term mortality and complications and to assess causality.

Level of evidence: Prognostic Level III.
