Background:
The purpose of this study was to determine if the presence of a standing
Diagnostic and Statistical Manual of Mental Disorders,
Fifth Edition, psychiatric diagnosis is associated with worse outcomes for patients who develop a confirmed fracture-related infection (FRI).
Materials and Methods:
Included patients had open or closed fractures managed with internal fixation and had confirmed FRIs. Baseline demographics, injury information, and outcomes were collected via chart review. All patients who had a diagnosis of psychiatric illness, which included depression, bipolar disorder, anxiety disorder, and schizophrenia, were identified. Patients with and without a psychiatric diagnosis were statistically compared.
Results:
Two hundred eleven patients were diagnosed with a confirmed FRI. Fifty-seven (27.0%) patients had a diagnosis of a psychiatric illness at the time of FRI diagnosis. Patients with a psychiatric diagnosis had a higher rate of smoking (56% vs 40%,
P
=.039) and drug use (39% vs 19%,
P
=.004) and a higher American Society of Anesthesiologists (ASA) classification (2.35±1.33 vs 1.96±1.22,
P
=.038); however, there were no other demographic differences. Clinical outcomes also did not differ between the groups, as patients with an FRI and a psychiatric diagnosis had a similar time to FRI diagnosis, similar confirmatory FRI characteristics, and a similar rate of reoperation. Furthermore, there was no difference between patients with FRI with and without a psychiatric diagnosis regarding rate of infection resolution (89% vs 88%,
P
=.718) or time to final follow-up (20.13±24.93 vs 18.11±21.81 months,
P
=.270).
Conclusion:
The presence of a psychiatric diagnosis does not affect clinical outcomes in the patient population with FRI. This is the first study exploring the impact of psychiatric illness on patient outcomes after a confirmed FRI diagnosis. [
