Top Ten Tips Palliative Care Clinicians Should Know About Buprenorphine

Substance Use Disorder, Opioid Use Disorder, and Symptom Management in Palliative Care: A Rapid Review of Evidence

Substance use disorder (SUD) affects more than 1 in 6 Americans older than 12 years and has become an increasingly relevant topic in palliative care. Lack of clear guidelines and fragmented care results in patient safety concerns and poor outcomes. This rapid review aims to present the current literature on opioid contracts/agreements, prescription drug monitoring database access, opioid risk assessment tools, and urine drug screening in the palliative care setting. Through a systematic process, we identified 19 articles published between 2018 and 2023 that pertained to substance use disorder and palliative care. Current risk mitigation strategies include prescription drug monitoring, opioid use agreements, risk assessment tools, urine drug screening, and the use of buprenorphine to manage pain. Prescription drug monitoring programs are state-based electronic databases that track controlled substances, and there are numerous risk assessment tools. Urine drug screening involves the use of both immunoassay and confirmatory chromatography to determine the presence or absence of either the prescribed controlled substance or unexpected findings including illicit drugs or prescription-controlled substances that are not prescribed to the patient. The goal of mitigating risk and reducing harm while providing expert symptom management is the challenge that palliative care transdisciplinary teams face as they continue to care for patients with substance use disorder. This review points to the need for further research on how to incorporate these harm-reducing strategies into clinical practice.

Creating a Palliative Care Clinic for Patients with Cancer Pain and Substance Use Disorder

BACKGROUND

Opioids are a first-line treatment for severe cancer pain. However, clinicians may be reluctant to prescribe opioids for patients with concurrent substance use disorders (SUD) or clinical concerns about non-prescribed substance use.

MEASURES

Patient volume, 60-day retention rate, and use of sublingual buprenorphine to treat opioid use disorder.

INTERVENTION

We created the Palliative Harm Reduction and Resiliency Clinic, a palliative care clinic founded on harm reduction principles and including formal collaboration with addiction psychiatry.

OUTCOMES

During the first 18 months, patient volume increased steadily; 70% of patients had at least one subsequent visit within 60 days of the initial appointment; and buprenorphine was prescribed for 55% of patients with opioid use disorder.

CONCLUSIONS/LESSONS LEARNED

The formal collaboration with addiction psychiatry and the integration of harm reduction principles and practices into ambulatory palliative care improved our ability to provide treatment to a previously underserved patient population with high symptom burden.

Clinician Ordering and Management Patterns of Urine Toxicology Results at a Cancer Center

CONTEXT

Opioid therapy is a cornerstone for treatment of cancer-related pain, but standardized management practices for patients with cancer and aberrant urine drug test (UDT) results are lacking.

OBJECTIVES

To identify the prevalence of UDT ordering (both screening and definitive testing) in the oncology setting and to examine clinician management practices for patients with cancer on opioid therapy with aberrant definitive UDT results.

METHODS

We conducted a retrospective chart review of patients with cancer on opioid therapy at an academic cancer center in the United States. Outcomes included UDT ordering patterns and clinician management practices in response to aberrant definitive UDT results.

RESULTS

Our study revealed an overall UDT ordering rate of 3.7% among 10,371 patients with cancer on opioid therapy. Among 143 patients for whom definitive UDTs were ordered, oncologists only ordered 14 (9.8%) UDTs, while palliative care ordered the majority (n = 129; 90.2%). Fifty-five (38.5%) patients had aberrant results, and the most common aberrancy was presence of illicit drugs 22 [15.4%]. Clinicians rarely made medication changes (20 [36.4%]) when UDT results were aberrant, and in the setting of possible fentanyl use (n = 8), only 3 (37.5%) patients were started/switched to methadone, and none were started/switched to buprenorphine.

CONCLUSION

Overall UDT ordering was infrequent for patients with cancer on opioid therapy, especially by oncologists, and clinicians rarely made prescribing changes when definitive UDT results were aberrant. More definitive guidance related to UDT ordering and opioid management are needed for patients with cancer and aberrant UDT results.

Real-World Dispensing of Buprenorphine in California during Prepandemic and Pandemic Periods

INTRODUCTION

The opioid overdose crisis in the United States has become a significant national emergency. Buprenorphine, a primary medication for individuals coping with opioid use disorder (OUD), presents promising pharmacokinetic properties for use in primary care settings, and is often delivered as a take-home therapy. The COVID-19 pandemic exacerbated the scarcity of access to buprenorphine, leading to dire consequences for those with OUD. Most existing studies, primarily focused on the immediate aftermath of the COVID-19 outbreak, highlight the challenges in accessing medications for opioid use disorder (MOUDs), particularly buprenorphine. However, these studies only cover a relatively short timeframe.

METHODS

To bridge this research gap, in our study, we utilized 33 months of California's prescription drug monitoring program (PDMP) data to provide insights into real-world buprenorphine dispensing trends since the onset of the pandemic from 2018 to 2021, focusing on outcomes such as patient counts, prescription volumes, prescriber involvement, days' supply, and dosage. Statistical analysis employed interrupted time series analysis to measure changes in trends before and during the pandemic.

RESULTS

We found no significant impact on patient counts or prescription volumes during the pandemic, although it impeded the upward trajectory of prescriber numbers that was evident prior to the onset of the pandemic. An immediate increase in days' supply per prescription was observed post-pandemic.

CONCLUSION

Our findings differ in comparison to previous data regarding the raw monthly count of patients and prescriptions. The analysis encompassed uninsured patients, offering a comprehensive perspective on buprenorphine prescribing in California. Our study's insights contribute to understanding the impact of COVID-19 on buprenorphine access, emphasizing the need for policy adjustments.

Evaluation of Low-dose Buprenorphine Initiation With Buprenorphine Buccal Films in Hospitalized Patients: A Retrospective Cohort Study

OBJECTIVE

Low-dose buprenorphine initiation (LDBI) strategies to transition patients from full opioid agonists to buprenorphine have previously been described using sublingual films, intravenous solution, transdermal patches, and, more recently, buccal films. The objective of this study was to describe the effectiveness of LDBI using novel titration schedules with buccal films.

METHODS

This is a retrospective cohort study of hospitalized patients with opioid use disorder (OUD) or physiologic dependence to opioids who underwent LDBI with buprenorphine buccal films at NYU Langone Health. Two LDBI protocols were evaluated, including a short titration schedule over 4 days and a long schedule over 7 days. The primary outcomes of interest included LDBI completion rates and incidence of opioid withdrawal.

RESULTS

Forty-two patients underwent 46 LDBIs at NYU Langone Health between October 2020 and April 2022. The cohort comprised patients with OUD (57%), chronic pain with OUD (33%), and chronic pain without OUD (10%). Indications for LDBI most commonly included co-occurring pain precluding discontinuation of full opioid agonists (72%), prior history of precipitated withdrawal (30%), and methadone use (23%). The overall completion rate of LDBI was 78%. Withdrawal was encountered in 33% of patients; however, only 2 patients required LDBI discontinuation as a result. On multivariate analysis, a diagnosis of OUD was independently associated with withdrawal during LDBI.

CONCLUSIONS

Buprenorphine buccal films can successfully be used off-label to facilitate LDBI in the hospital setting. We present 4- and 7-day titration protocols, which were well-tolerated, and provide practical considerations for use.

Opioid Risk Mitigation Practices of Interprofessional Oncology Personnel: Results From a Cross-Sectional Survey

BACKGROUND

This study explored the risk mitigation practices of multidisciplinary oncology health-care personnel for the nonmedical use of opioids in people with cancer.

METHODS

An anonymous, cross-sectional descriptive survey was administered via email to eligible providers over 4 weeks at The Ohio State University's Arthur G. James Cancer Hospital. The survey asked about experiences and knowledge related to opioid use disorders.

RESULTS

The final sample of 773 participants included 42 physicians, 213 advanced practice providers (APPs consisted of advanced practice nurses, physician assistants, and pharmacists), and 518 registered nurses. Approximately 40% of participants responded feeling "not confident" in addressing medication diversion. The most frequent risk reduction measure was "Checking the prescription drug monitoring program" when prescribing controlled medications, reported by physicians (n = 29, 78.4%) and APPs (n = 164, 88.6%).

CONCLUSION

People with cancer are not exempt from the opioid epidemic and may be at risk for nonmedical opioid use (NMOU) and substance use disorders. Implementing risk reduction strategies with every patient, with a harm reduction versus abstinence focus, minimizes harmful consequences and improves. This study highlights risk mitigation approaches for NMOU, representing an opportunity to improve awareness among oncology health-care providers. Multidisciplinary oncology teams are ideally positioned to navigate patients through complex oncology and health-care journeys.
