Clinical Scorecard: Current Approaches to Managing Infective Endocarditis in Injection Drug Users: Insights from Tennessee Healthcare Facilities
At a Glance
Category
Detail
Condition
Infective endocarditis in people who inject drugs (PWID)
Key Mechanisms
Bacterial infection of heart valves, often involving MRSA, associated with injection drug use
Target Population
People who inject drugs diagnosed with infective endocarditis in Tennessee
Care Setting
Tennessee healthcare facilities including community hospitals and specialized centers
Key Highlights
Most facilities (88%) screen for substance use disorders on admission but only 24% offer addiction consultation services.
Antibiotic therapy is primarily completed inpatient (94%) or at skilled nursing facilities (75%), with less frequent use of oral antibiotics, long-acting lipoglycopeptides, or outpatient parenteral therapy.
Only 7 of 16 facilities perform cardiac surgery and 6 perform catheter-based interventions for endocarditis in PWID.
Guideline-Based Recommendations
Diagnosis
Screen all PWID admitted with endocarditis for substance use disorders.
Management
Complete intravenous antibiotic therapy inpatient or at skilled nursing facilities.
Consider alternative antibiotic strategies such as oral antibiotics, long-acting lipoglycopeptides, or outpatient parenteral antibiotic therapy where feasible.
Provide addiction consultation services to address underlying substance use disorders.
Monitoring & Follow-up
Monitor treatment adherence and complications during inpatient or skilled nursing facility stays.
Assess for potential need and timing of cardiac surgery or catheter-based interventions.
Risks
Increased mortality in young adults with substance use disorders despite overall mortality decline.
Longer hospital stays and risk of unplanned discharges in PWID.
Potential provider stigmatization and limited addiction resources impacting care quality.
Patient & Prescribing Data
People who inject drugs with infective endocarditis treated in Tennessee healthcare facilities
Majority receive intravenous antibiotics inpatient or at skilled nursing facilities; less than half have access to addiction services or alternative antibiotic regimens.
Clinical Best Practices
Implement routine screening for substance use disorders on admission for PWID with endocarditis.
Expand access to addiction consultation services to improve comprehensive care.
Utilize alternative antibiotic therapies (oral, long-acting agents, outpatient parenteral therapy) to enhance treatment flexibility and potentially reduce hospital length of stay.
Coordinate multidisciplinary care including infectious disease, addiction specialists, and cardiac surgery teams.
Develop clear institutional policies to address logistical challenges and reduce provider stigmatization.
