Management of Infective Endocarditis in People Who Inject Drugs: A Scientific Statement From the American Heart Association.

BACKGROUND: The American Heart Association has sponsored both guidelines and scientific statements that address the diagnosis, management, and prevention of infective endocarditis. As a result of the unprecedented and increasing incidence of infective endocarditis cases among people who inject drugs, the American Heart Association sponsored this original scientific statement. It provides a more in-depth focus on the management of infective endocarditis among this unique population than what has been provided in prior American Heart Association infective endocarditis-related documents. METHODS: A writing group was named and consisted of recognized experts in the fields of infectious diseases, cardiology, addiction medicine, and cardiovascular surgery in October 2021. A literature search was conducted in Embase on November 19, 2021, and multiple terms were used, with 1345 English-language articles identified after removal of duplicates. CONCLUSIONS: Management of infective endocarditis in people who inject drugs is complex and requires a unique approach in all aspects of care. Clinicians must appreciate that it requires involvement of a variety of specialists and that consultation by addiction-trained clinicians is as important as that of more traditional members of the endocarditis team to improve infective endocarditis outcomes. Preventive measures are critical in people who inject drugs and are cured of an initial bout of infective endocarditis because they remain at extremely high risk for subsequent bouts of infective endocarditis, regardless of whether injection drug use is continued.

Cardiac surgeons' perspectives and practices regarding people who use drugs: A scoping review.

BACKGROUND AND AIM OF STUDY: The rising rates of drug use and associated cardiovascular complications, particularly infective endocarditis, have led to poorer health outcomes for people who use drugs (PWUD). The objectives of this scoping review were to identify (1) attitudes of cardiac surgeons toward PWUD and (2) challenges faced in the surgical treatment of drug use-related disease. METHODS: A comprehensive literature search of three databases was performed with this assistance of a medical librarian. Articles were screened and analyzed for common themes by two independent authors. After literature review, a scoping review was conducted according to preferred reporting items for systematic reviews and meta-analyses and Joanna Briggs Institute guidelines, summarizing existing evidence. RESULTS: Analysis of 35 qualified articles revealed eight themes regarding the perspectives and practices of cardiac surgeons toward PWUD: (1) need for multidisciplinary care teams (45.7%); (2) insufficient resources for treatment of underlying substanceuse disorders (40.0%); (3) stigma toward PWUD (37.1%); (4) willingness of surgeons to operate (31.4%); (5) incomplete guidelines for surgical management of drug-use related infective endocarditis (17.1%); (6) recognizing the importance of psychosocial factors (14.3%); (7) use of drug abstinence contracts (14.3%); and (8) use of stigmatizing language to describe PWUD and/or sterile injection (40.0%). CONCLUSIONS: Provision of equitable care for PWUD requires effort from multiple disciplines including cardiothoracic surgeons, infectious disease specialists, addiction medicine specialists, and social workers. Additionally, further research is needed to gather sufficient data for evidence-based guidelines in the treatment of cardiac complications in PWUD.

Cardiac surgeons' practices and attitudes toward addiction care for patients with substance use disorders.

INTRODUCTION: Rates of injection-drug use associated infective endocarditis (IDU-IE) are rising, and most patients with IDU-IE do not receive addiction care during hospitalization. We sought to characterize cardiac surgeons' practices and attitudes toward patients with IDU-IE due to their integral role treating them. METHODS: This is a survey of 201 cardiac surgeons in the U.S who were asked about the addiction care they engage for patients with IDU-IE along with questions pertaining to stigma against people who use drugs (PWUD). Descriptive statistics and multivariable logistic regression were used to identify patterns in surgeons' practices and determine associations between attitudes toward substance use disorder (SUD) and beliefs about medications for opioid use disorder (MOUD). RESULTS: A minority of surgeons have access to specialty addiction services (35%) in their hospital, but when available 93% consult them for patients with IDU-IE. A quarter of surgeons reported thinking that SUD is a choice and do not believe MOUD have a role in reducing IDU-IE recurrence. Conversely, 69% of surgeons agreed with the disease model of addiction and were four times more likely to believe that MOUD has a role in reducing IDU-IE recurrence (aOR 4.09, 95% CI 1.8-9.27, p = 0.001). CONCLUSION: Access to addiction specialists is limited in most hospital settings, but when available, most surgeons report consulting them and supporting MOUD. However, a significant proportion of surgeons hold non-evidence-based attitudes toward SUD and PWUD. This suggests that lack of education and stigma may affect the care of patients with IDU-IE, highlighting the need for education about, and destigmatization of addiction within health systems.

A chronic opioid therapy dose reduction policy in primary care.

BACKGROUND: High-dose opioids prescribed for the treatment of chronic pain have been associated with increased risk of opioid overdose. Health systems and states have responded by developing opioid dose limitation policies. Little is known about how these policies affect prescribing practices or characteristics of patients who respond best to opioid tapers from high-dose opioids. METHODS: We conducted a retrospective cohort study to evaluate change in total opioid dose after the implementation of a provider education intervention and a 120 mg morphine equivalents per day (MED) opioid dose limitation policy in one academic primary care clinic. We compared opioid prescriptions 1 year before and 1 year after the intervention. We used univariate and multivariate logistic regression to assess which patient characteristics predicted opioid dose reduction from high opioid dose. RESULTS: Out of a total of 516 patients prescribed chronic opioid therapy, 116 patients (22%) were prescribed high-dose opioid therapy (>120 mg MED). After policy adoption, the average daily dose of opioids declined by 64 mg MED (95% confidence interval [CI]: 32-96; P < .001) and 41 patients (37%) on high-dose opioids tapered their doses below 120 mg MED (Tapered to Safer Dose group). In multivariate analyses, female sex was the only significant association with dose taper; female patients were less likely to taper to a safer dose (adjusted odds ratio [aOR] = 0.28, 95% CI: 0.11-0.70). CONCLUSIONS: A combined intervention of education and a practice policy that limits opioid doses for patients prescribed chronic opioid therapy may be an important component of system-level strategies to reduce opioid misuse and overdose; it may also help identify patients suitable for medication-assisted treatment for opioid use disorder. Specific strategies may be needed to assist women with opioid dose tapers.

The American Society of Addiction Medicine Clinical Practice Guideline Development Methodology.

ABSTRACT: The American Society of Addiction Medicine (ASAM) has published clinical practice guidelines (CPGs) since 2015. As ASAM's CPG work continues to develop, it maintains an organizational priority to establish rigorous standards for the trustworthy production of these important documents. In keeping with ASAM's mission to define and promote evidence-based best practices in addiction prevention, treatment, and recovery, ASAM has rigorously updated its CPG methodology to be in line with evolving international standards. The CPG Methodology and Oversight Subcommittee was formed to establish and publish a methodology for the development of ASAM CPGs and to develop an ASAM CPG strategic plan. This article provides a focused overview of the ASAM CPG methodology.

National HIV and HCV Screening Rates for Hospitalized People who Use Drugs Are Suboptimal and Heterogeneous Across 11 US Hospitals.

Background: To end the HIV and hepatitis C virus (HCV) epidemics, people who use drugs (PWUD) need more opportunities for testing. While inpatient hospitalizations are an essential opportunity to test people who use drugs (PWUD) for HIV and HCV, there is limited research on rates of inpatient testing for HIV and HCV among PWUD. Methods: Eleven hospital sites were included in the study. Each site created a cohort of inpatient encounters associated with injection drug use. From these cohorts, we collected data on HCV and HIV testing rates and HIV testing consent policies from 65 276 PWUD hospitalizations. Results: Hospitals had average screening rates of 40% for HIV and 32% for HCV, with widespread heterogeneity in screening rates across facilities. State consent laws and opt-out testing policies were not associated with statistically significant differences in HIV screening rates. On average, hospitals that reflexed HCV viral load testing on HCV antibody testing did not have statistically significant differences in HCV viral load testing rates. We found suboptimal testing rates during inpatient encounters for PWUD. As treatment (HIV) and cure (HCV) are necessary to end these epidemics, we need to prioritize understanding and overcoming barriers to testing.

Sex differences in the medical care of VA patients with chronic non-cancer pain.

OBJECTIVE: Despite a growing number of women seeking medical care in the veterans affairs (VA) system, little is known about the characteristics of their chronic pain or the pain care they receive. This study sought to determine if sex differences are present in the medical care veterans received for chronic pain. DESIGN: Retrospective cohort study using VA administrative data. SUBJECTS: The subjects were 17,583 veteran patients with moderate to severe chronic non-cancer pain treated in the Pacific Northwest during 2008. METHODS: Multivariate logistic regression assessed for sex differences in primary care utilization, prescription of chronic opioid therapy, visits to emergency departments for a pain-related diagnosis, and physical therapy referral. RESULTS: Compared with male veterans, female veterans were more often diagnosed with two or more pain conditions, and had more of the following pain-related diagnoses: fibromyalgia, low back pain, inflammatory bowel disease, migraine headache, neck or joint pain, and arthritis. After adjustment for demographic characteristics, pain diagnoses, mental health diagnoses, substance use disorders, and medical comorbidity, women had lower odds of being prescribed chronic opioid therapy (adjusted OR [AOR] 0.67, 95% CI 0.58-0.78), greater odds of visiting an emergency department for a pain-related complaint (AOR 1.40, 95% CI 1.18-1.65), and greater odds of receiving physical therapy (AOR 1.19, 95% CI 1.05-1.33). Primary care utilization was not significantly different between sexes. CONCLUSIONS: Sex differences are present in the care female veterans receive for chronic pain. Further research is necessary to understand the etiology of the observed differences and their associations with clinical outcomes.

Low-dose Initiation of Buprenorphine in Hospitalized Patients Using Buccal Buprenorphine: A Case Series.

OBJECTIVE: To describe a low-dose buprenorphine initiation strategy with buccal buprenorphine. METHODS: This is a case series of hospitalized patients with opioid use disorder (OUD) and/or chronic pain who underwent low-dose buprenorphine initiation with buccal buprenorphine to sublingual buprenorphine. Results are descriptively reported. RESULTS: Forty-five patients underwent low-dose buprenorphine initiation from January 2020 to July 2021. Twenty-two (49%) patients had OUD only, 5 (11%) patients had chronic pain only, and 18 (40%) patients had both OUD and chronic pain. Thirty-six (80%) patients had documented history of heroin or non-prescribed fentanyl use before admission. Acute pain in 34 (76%) patients was the most commonly documented rationale for low-dose buprenorphine initiation. Methadone was the most common outpatient opioid utilized before admission (53%). The addiction medicine service consulted on 44 (98%) cases and median length of stay was approximately 2 weeks. Thirty-six (80%) patients completed the transition to sublingual buprenorphine with a median completion dose of 16 mg daily. Of the 24 patients (53%) with consistently documented Clinical Opiate Withdrawal Scale scores, no patients experienced severe opioid withdrawal. Fifteen (62.5%) experienced mild or moderate withdrawal and 9 (37.5%) experienced no withdrawal (Clinical Opiate Withdrawal Scale score <5) during the entire process. Continuity of postdischarge prescription refills ranged from 0 to 37 weeks and the median number of buprenorphine refills was 7 weeks. CONCLUSIONS: Low-dose buprenorphine initiation with buccal buprenorphine to sublingual buprenorphine was well tolerated and can be safely and effectively utilized for patients whose clinical scenario precludes traditional buprenorphine initiation strategies.

Precipitated Opioid Withdrawal Treated With Ketamine in a Hospitalized Patient: A Case Report.

BACKGROUND: Although initiating buprenorphine in the presence of full opioid agonists has always been a clinical dilemma, the transition to primarily fentanyl in the drug supply has increased the urgency to find appropriate treatments for precipitated opioid withdrawal (POW). Although rare, lack of evidence on how to best treat POW threatens clinician and patient comfort in initiating life-saving medication for opioid use disorder. Ketamine has been used in emergency department settings to treat POW; this is the first case report of ketamine use in a hospitalized patient. CASE SUMMARY: A 38-year-old male patient with severe opioid use disorder presented to the emergency department with suicidality and opioid withdrawal 24 hours after last fentanyl use. In the first 24 hours of admission, he received sublingual buprenorphine-naloxone (BNX) 16-4 mg, resulting in Clinical Opiate Withdrawal Scale score increasing from 13 to over 36. The patient was admitted, and addiction medicine was consulted. The patient was diagnosed with POW, started on ketamine infusion, and given additional BNX 8-2 mg. Twelve hours after the ketamine infusion, the patient's Clinical Opiate Withdrawal Scale score improved to 18 but remained elevated. He received a second ketamine infusion plus additional BNX with complete resolution of symptoms within 8 hours, and he was stabilized and discharged on BNX 24-6 mg daily. CLINICAL SIGNIFICANCE: Ketamine is a promising treatment for POW due to its potentiation of µ-opioid receptor-mediated signaling. This is the first case to describe POW in the inpatient hospital setting. More research is needed to establish the effectiveness and feasibility of ketamine as treatment for POW.

Multidisciplinary Management of Opioid Use-Related Infective Endocarditis: Treatment, QTc Values, and Cardiac Arrests due to Ventricular Fibrillation.

(1) Background: The opioid epidemic has led to an increase in cardiac surgery for infective endocarditis (IE-CS) related to injection use of opioids (OUD) and other substances and a call for a coordinated approach to initiate substance use disorder treatment, including medication for OUD (MOUD), during IE-CS hospitalizations. We sought to determine the effects of the initiation of a multi-disciplinary endocarditis evaluation team (MEET) on MOUD use, electrocardiographic QTc measurements and cardiac arrests due to ventricular fibrillation (VF) in patients with OUD. (2) Methods and Results: A historical group undergoing IE-CS at Yale-New Haven Hospital prior to MEET initiation, Group I (43 episodes of IE-CS, 38 patients) was compared to 24 patients undergoing IE-CS after MEET involvement (Group II). Compared to Group l, Group II patients were more likely to receive MOUD (41.9 vs. 95.8%, p < 0.0001), predominantly methadone (41.9 vs. 79.2%, p = 0.0035) at discharge. Both groups had similar QTcs: approximately 30% of reviewed electrocardiograms had QTcs ≥ 470 ms and 17%, QTcs ≥ 500 ms. Cardiac arrests due to VF were not uncommon: Group I: 9.3% vs. Group II: 8.3%, p = 0.8914. Half occurred in the 1-2 months after surgery and were contributed to by pacemaker malfunction/ management and half were related to opioid use. (3) Conclusions: MEET was associated with increased MOUD (predominantly methadone) use during IE-CS hospitalizations without an increase in QTc prolongation or cardiac arrest due to VF compared to Group I, but events occurred in both groups. These arrests were associated with pacemaker issues or a return to opioid use. Robust follow-up of IE-CS patients is essential, as is further research to clarify the longer-term effects of MEET on outcomes.

Response to substance use during hospitalization: A survey study of current and ideal policies and practices.

People may use nonprescribed substances during an acute hospitalization. Hospital policies and responses can be stigmatizing, involve law enforcement, and lead to worse patient outcomes, including patient-directed discharge. In the United States, there is currently little data on hospital policies that address the use of substances during hospitalization. In this cross-sectional study, we surveyed clinicians at US hospitals with Accreditation Council of Graduate Medical Education (ACGME)-accredited addiction medicine fellowships about their current practices and policies and what they would include in an ideal policy. We had 77 responses from 55 out of 86 ACGME-addiction medicine fellowships (63.9%). Respondents identified policies at 21.8% of the institutions surveyed. Current responses to inpatient substance use vary, though most do not match what clinicians identify as an ideal response. Our results suggest that the use of nonprescribed substances during a hospitalization may be common, but a majority of hospitals likely do not have patient-centered policies to address this.

ASAM Clinical Considerations: Buprenorphine Treatment of Opioid Use Disorder for Individuals Using High-potency Synthetic Opioids.

ABSTRACT: Treatment of opioid use disorder (OUD) with buprenorphine has evolved considerably in the last decade as the scale of the OUD epidemic has increased along with the emergence of high-potency synthetic opioids (HPSOs) and stimulants in the drug supply. These changes have outpaced the development of prospective research, so a clinical consideration document based on expert consensus is needed to address pressing clinical questions. This clinical considerations document is based on a narrative literature review and expert consensus and will specifically address considerations for changes to the clinical practice of treatment of OUD with buprenorphine for individuals using HPSO. An expert panel developed 6 key questions addressing buprenorphine initiation, stabilization, and long-term treatment for individuals with OUD exposed to HPSO in various treatment settings. Broadly, the clinical considerations suggest that individualized strategies for buprenorphine initiation may be needed. The experience of opioid withdrawal negatively impacts the success of buprenorphine treatment, and attention to its management before and during buprenorphine initiation should be proactively addressed. Buprenorphine dose and dosing frequency should be individualized based on patients' treatment needs, the possibility of novel components in the drug supply should be considered during OUD treatment, and all forms of opioid agonist treatment should be offered and considered for patients. Together, these clinical considerations attempt to be responsive to the challenges and opportunities experienced by frontline clinicians using buprenorphine for the treatment of OUD in patients using HPSOs and highlight areas where prospective research is urgently needed.

Promoting alcohol treatment engagement post-hospitalization with brief intervention, medications and CBT4CBT: protocol for a randomized clinical trial in a diverse patient population.

BACKGROUND: Alcohol use disorder (AUD) commonly causes hospitalization, particularly for individuals disproportionately impacted by structural racism and other forms of marginalization. The optimal approach for engaging hospitalized patients with AUD in treatment post-hospital discharge is unknown. We describe the rationale, aims, and protocol for Project ENHANCE (ENhancing Hospital-initiated Alcohol TreatmeNt to InCrease Engagement), a clinical trial testing increasingly intensive approaches using a hybrid type 1 effectiveness-implementation approach. METHODS: We are randomizing English and/or Spanish-speaking individuals with untreated AUD (n = 450) from a large, urban, academic hospital in New Haven, CT to: (1) Brief Negotiation Interview (with referral and telephone booster) alone (BNI), (2) BNI plus facilitated initiation of medications for alcohol use disorder (BNI + MAUD), or (3) BNI + MAUD + initiation of computer-based training for cognitive behavioral therapy (CBT4CBT, BNI + MAUD + CBT4CBT). Interventions are delivered by Health Promotion Advocates. The primary outcome is AUD treatment engagement 34 days post-hospital discharge. Secondary outcomes include AUD treatment engagement 90 days post-discharge and changes in self-reported alcohol use and phosphatidylethanol. Exploratory outcomes include health care utilization. We will explore whether the effectiveness of the interventions on AUD treatment engagement and alcohol use outcomes differ across and within racialized and ethnic groups, consistent with disproportionate impacts of AUD. Lastly, we will conduct an implementation-focused process evaluation, including individual-level collection and statistical comparisons between the three conditions of costs to providers and to patients, cost-effectiveness indices (effectiveness/cost ratios), and cost-benefit indices (benefit/cost ratios, net benefit [benefits minus costs). Graphs of individual- and group-level effectiveness x cost, and benefits x costs, will portray relationships between costs and effectiveness and between costs and benefits for the three conditions, in a manner that community representatives also should be able to understand and use. CONCLUSIONS: Project ENHANCE is expected to generate novel findings to inform future hospital-based efforts to promote AUD treatment engagement among diverse patient populations, including those most impacted by AUD.

Top Ten Tips Palliative Care Clinicians Should Know About Buprenorphine.

Pain management in palliative care (PC) is becoming more complex as patients survive longer with life-limiting illnesses and population-wide trends involving opioid misuse become more common in serious illness. Buprenorphine, a generally safe partial mu-opioid receptor agonist, has been shown to be effective for both pain management and opioid use disorder. It is critical that PC clinicians become comfortable with indications for its use, strategies for initiation while understanding risks and benefits. This article, written by a team of PC and addiction-trained specialists, including physicians, nurse practitioners, social workers, and a pharmacist, offers 10 tips to demystify buprenorphine use in serious illness.

Clinical Management of Opioid Withdrawal.

Appropriate clinical management of opioid withdrawal is a crucial bridge to long-term treatment for opioid use disorder (OUD), because it is a high-risk time for potential opioid overdose and relapse. We provide a narrative review of evidence-based opioid withdrawal management strategies applicable to a variety of treatment settings and geographies. The goals of opioid withdrawal management include relieving suffering associated with withdrawal, providing appropriate diagnosis and screening, engaging patients in initiation of OUD treatment, and using harm reduction strategies, all guided by a patient-centered approach to care. In addition, we discuss complex cases, relapse prevention strategies, and new developments in opioid withdrawal management.

SOAPs and SUDs: Patients With Substance Use Disorders and What Clinicians Should Know About the Cures Act.

The 21st Century Cures Act of 2016 mandates that patients have access to their clinical notes, labs, and imaging through electronic portals and requires information sharing among healthcare entities. We provide practical tips to healthcare professionals on best practices in documenting substance use in the era of transparent electronic medical records, as well as provide guidance on the application of the Cures Act information blocking exceptions for their patients who use substances.
