Results:

Of the 233 total patients, 127 patients had bacteremia and 106 patients had pocket infection. In the bacteremia group, 74% underwent delayed extraction (mean 15.2 days); the majority were transfers from outside hospitals and presented at a later time in their inpatient course; delayed extraction was also associated with septic shock (odds ratio [OR], 5.39; 95% confidence interval [CI], 1.23-23.67; p = 0.026), acute kidney injury (OR, 5.61; 95% CI, 2.15-14.63; p < 0.001), respiratory failure (OR, 5.52; 95% CI, 1.25-24.41; p = 0.024), and decompensated heart failure (OR, 3.32; 95% CI, 1.10-10.05; p = 0.033); 11 died among the delayed extraction group and none in the early group with septic shock as most common cause of death (n = 8). Isolated pocket infection patients were also more likely to be transfers from outside hospitals at a later time after initial presentation; 15% had delayed extraction (mean 10.7 days) with higher rates of acute kidney injury (OR, 3.45; 95% CI, 1.11-10.77; p = 0.033) and respiratory failure (OR, 10.29; 95% CI, 1.26-83.93; p = 0.030); one patient died of cardiac arrest, and no patients died in the early extraction group. Delayed extraction in both bacteremia and pocket infection groups was significantly associated with increased 1-year mortality. Overall complication rate (3%) was similar between groups.
