Abstract:
The epidemiology of infective endocarditis (IE) continues to evolve in areas affected by the opioid epidemic. Understanding the demographics of the disease allows us to better tailor therapy towards this at-risk population. This was an observational study of adults (age ≥ 18) admitted to the University of Kentucky hospital with IE between January 2009 and December 2018. 1,255 patients were included in the final analysis. The mean age was 42 years, 45% were female and injection drug use was seen in 66% of patients. On multivariable analysis, higher Charlson comorbidity indices, left sided, and multivalve involvement were associated with increased mortality, whereas surgical intervention demonstrated a trend towards lower mortality. Our results highlight the alarming increase in injection drug use related IE and the high mortality rates despite therapeutic advances. Patients with left sided IE, multivalve involvement and a higher Charlson comorbidity index had decreased survival.

HAIs significantly increase the cost of health care. Extended stays in healthcare institutions, increased disability, increased costs of medications, including specialized antibiotics, and prolonged recovery times add to the patient's expenses and the healthcare institution and funding bodies.
