Background
Periprosthetic infection has been linked to risk factors such as diabetes, obesity, and smoking amongst others. This study examined the relationship between common patient comorbidities and hip periprosthetic infection outcomes.
Methods
We retrospectively reviewed the records of 149 culture-positive periprosthetic hip infections at our tertiary care center that underwent treatment between 2005 and 2015. Baseline characteristics as well as common comorbidities were analyzed with relation to rates of successfully treated infection, total surgeries for infection, and cumulative length of hospitalization using multivariable analysis.
Results
Patients with coronary artery disease or anemia had significantly lower rate of successfully treated infection. Patients with anemia or chronic pulmonary disease underwent significantly more surgery, and patients with chronic pulmonary disease, psychiatric disease, anemia, or diabetes spent significantly longer time in hospital.
Conclusion
Potentially modifiable cardiovascular, respiratory, and psychiatric diseases were associated with decreased rate of successfully treated infection, more surgery, and longer hospitalization in treatment for hip peri-prosthetic infection in multivariable analysis.
