Repeat Valve Replacement in a Person With Substance Use Disorder: What Does Justice Dictate?

Ethics Consultations Related to Opioid Use Disorder

BACKGROUND

The opioid epidemic has resulted in an increased number of patients with opioid use disorder (OUD) hospitalized for serious medical conditions. The intersection between hospital ethics consultations and the opioid crisis has not received significant attention.

OBJECTIVE

The aim of this study was to characterize ethics consult questions among inpatients with OUD at our institution, Massachusetts General Hospital.

METHODS

We conducted a single-center retrospective cohort study of ethics consultations from January 1, 1993 to December 31, 2017 at Massachusetts General Hospital.

RESULTS

Between 1993 and 2017, OUD played a central role in ethics consultations in 43 of 1061 (4.0%) cases. There was an increase in these requests beginning in 2009, rising from 1.4% to 6.8% of consults by 2017. Compared with other ethics cases, individuals with OUD were significantly younger (P < 0.001), more likely to be uninsured or underinsured (P < 0.001), and more likely to have a comorbid mental health diagnosis (P = 0.001). The most common reason for consultation involved continuation of life-sustaining treatment in the setting of overdose with neurological injury or severe infection. Additional reasons included discharge planning, challenges with pain management and behavior, and the appropriateness of surgical intervention, such as repeat valve replacement or organ transplant. Health care professionals struggled with their ethical obligations to patients with OUD, including when to treat pain with narcotics and how to provide longitudinal care for patients with limited resources outside of the hospital.

CONCLUSION

The growing opioid epidemic corresponds with a rise in ethics consultations for patients with OUD. Similar factors associated with OUD itself, including comorbid mental health diagnoses and concerns about relapse, contributed to the ethical complexities of these consults.

Impact of Substance Use Disorder on Midterm Mortality After Valve Surgery for Endocarditis

BACKGROUND

Fueled by the burgeoning opioid epidemic, valve surgeries for substance use disorder-related infective endocarditis (SUD-IE) are increasing. The impact of substance use disorder on postvalve replacement morbidity needs further investigation.

METHODS

We queried The Society of Thoracic Surgeons Adult Cardiac Surgery Database for all valve surgeries for infective endocarditis at Tufts Medical Center (2002-2016) and collected demographic and disease-related data, including timing of mortality subclassified as short-term (<6 months including operative), midterm (6 months to 5 years), and extended-term (>5 years). Patients with documentation of illicit drug use before the operation were considered to have SUD-IE. Deaths were confirmed through review of medical record and matching with the Massachusetts Vital Statistics Database. We performed univariate and multivariate proportional hazard regressions examining the impact of substance use disorder mortality in people who received a valve replacement.

RESULTS

In the cohort of 228 patients, 80 (35%) had SUD-IE. Eight-six people (38%) died, and overall mortality was higher in people with SUD-IE compared with non-SUD-IE (48% vs 32%, P = .025). SUD-IE was associated with a higher risk of overall mortality (adjusted hazard ratio, 2.41; 95% confidence interval, 1.38-4.20; P = .002). Although the difference between short-term or extended-term mortality was not significant, SUD-IE was associated with increased frequency of midterm mortality (53% vs 31%, P = .003).

CONCLUSIONS

Our data reflect high rates of postvalve surgery morbidity and mortality in people with SUD-IE at a tertiary care center. The midterm postoperative period is a vulnerable period for people with SUD-IE worthy of further investigation.
