Risk Factors Associated with Pyogenic Spinal Infections among Intravenous Drug Users and Nonusers

Area of Science:

• Infectious Diseases
• Spinal Infections
• Public Health

Background:

• Pyogenic spinal infections present unique challenges in patient management.
• Understanding demographic and comorbidity differences is crucial for optimizing care.
• Intravenous drug abuse (IVDA) is a growing concern in healthcare settings.

Purpose of the Study:

• To compare patient factors, presentation, treatment, and outcomes of pyogenic spinal infections between intravenous drug users (IVDA) and non-users (non-IVDA).
• To identify distinct characteristics and healthcare needs of these two patient populations.

Main Methods:

• Retrospective case series analysis of patients with primary pyogenic spinal infections.
• Exclusion of postsurgical infections.
• Statistical comparison of demographic, clinical, and outcome data between IVDA and non-IVDA groups using RStudio.

Main Results:

• The study included 50 patients; 14% were IVDA.
• IVDA patients were significantly younger (mean age 50.6 vs. 61.9 years) and had higher rates of smoking and psychiatric disorders.
• Non-IVDA patients were more likely to have comorbidities like diabetes, chronic kidney disease, and malignancy.

Conclusions:

• Two distinct patient populations emerged: younger IVDA patients with psychiatric issues and older non-IVDA patients with medical comorbidities.
• IVDA patients experienced challenges in accessing continued psychiatric and addiction treatment post-discharge.
• Further research with larger sample sizes is needed to explore healthcare resource consumption differences.
