Current state of opioid stewardship.

PURPOSE: The opioid epidemic continues to result in significant morbidity and mortality even within hospitals where opioids are the second most common cause of adverse events. Opioid stewardship represents one model for hospitals to promote safe and rational prescribing of opioids to mitigate preventable adverse events in alliance with new Joint Commission standards. The purpose of this study was to identify the prevalence of current hospital practices to improve opioid use. METHODS: A cross-sectional survey of hospital best practices for opioid use was electronically distributed via electronic listservs in March 2018 to examine the presence of an opioid stewardship program and related practices, including formulary restrictions, specialist involvement for high-risk patients, types of risk factors screened, and educational activities. RESULTS: Among 133 included hospitals, 23% reported a stewardship program and 14% reported a prospective screening process to identify patients at high risk of opioid-related adverse events (ORAEs). Among those with a prospective screening process, there was variability in ORAE risk factor screening. Formulary restrictions were dependent on specific opioids and formulations. Patient-controlled analgesia was restricted at 45% of hospitals. Most hospitals reported having a pain management service (90%) and a palliative care service providing pain management (67%). CONCLUSION: The absence of opioid stewardship and prospectively screening ORAEs represents a gap in current practice at surveyed hospitals. Hospitals have an opportunity to implement and refine best practices such as access to pain management specialists, use of formulary restrictions, and retrospective and prospective monitoring of adverse events to improve opioid use.

Universal premedication and therapeutic drug monitoring for asparaginase-based therapy prevents infusion-associated acute adverse events and drug substitutions.

BACKGROUND: Asparaginase is a critical component of lymphoblastic leukemia therapy, with intravenous pegaspargase (PEG) as the current standard product. Acute adverse events (aAEs) during PEG infusion are difficult to interpret, representing a mix of drug-inactivating hypersensitivity and noninactivating reactions. Asparaginase Erwinia chrysanthemi (ERW) is approved for PEG hypersensitivity, but is less convenient, more expensive, and yields lower serum asparaginase activity (SAA). We began a policy of universal premedication and SAA testing for PEG, hypothesizing this would reduce aAEs and unnecessary drug substitutions. PROCEDURE: Retrospective chart review of patients receiving asparaginase before and after universal premedication before PEG was conducted, with SAA performed 1 week later. We excluded patients who had nonallergic asparaginase AEs. Primary end point was substitution to ERW. Secondary end points included aAEs, SAA testing, and cost. RESULTS: We substituted to ERW in 21 of 122 (17.2%) patients pre-policy, and 5 of 68 (7.4%) post-policy (RR, 0.427; 95% CI, 0.27-0.69, P = 0.028). All completed doses of PEG yielded excellent SAA (mean, 0.90 units/mL), compared with ERW (mean, 0.15 units/mL). PEG inactivation post-policy was seen in 2 of 68 (2.9%), one silent and one with breakthrough aAE. The rate of aAEs pre/post-policy was 17.2% versus 5.9% (RR, 0.342; 95% CI, 0.20-0.58, P = 0.017). Grade 4 aAE rate pre/post-policy was 15% versus 0%. Cost analysis predicts $125 779 drug savings alone per substitution prevented ($12 402/premedicated patient). CONCLUSIONS: Universal premedication reduced substitutions to ERW and aAE rate. SAA testing demonstrated low rates of silent inactivation, and higher SAA for PEG. A substantial savings was achieved. We propose universal premedication for PEG be standard of care.

Chimeric Antigen Receptor T-Cell Therapy.

Patients with relapsed or refractory (R/R) cancers have a poor prognosis and limited treatment options. The recent approval of 2 chimeric antigen receptor (CAR) autologous T-cell products for R/R B-cell acute lymphoblastic leukemia and non-Hodgkin's lymphoma treatment is setting the stage for what is possible in other diseases. However, there are important factors that must be considered, including patient selection, toxicity management, and costs associated with CAR T-cell therapy. To begin to address these issues, NCCN organized a task force consisting of a multidisciplinary panel of experts in oncology, cancer center administration, and health policy, which met for the first time in March 2018. This report describes the current state of CAR T-cell therapy and future strategies that should be considered as the application of this novel immunotherapy expands and evolves.

Development and implementation of procedures for outpatient naloxone prescribing at a large academic medical center.

PURPOSE: An interprofessional initiative to operationalize outpatient naloxone prescribing at a large academic medical center is described. SUMMARY: The initiative was carried out by a work group of clinical pharmacists and pharmacy administrators in collaboration with physicians and nursing staff leaders from multiple practice settings. An opioid overdose risk-assessment guide was developed on the basis of literature review and expert opinion. An institutional policy to guide identification of high-risk patient populations and facilitate naloxone prescribing and dispensing was developed and vetted by multiple expert committees. Patient education materials were created, and patients at high risk for opioid overdose were educated about overdose risk factors and naloxone use by a pharmacist and/or nurse before discharge or, in some cases, by outpatient pharmacists; when feasible, patients' friends, family members, and/or caregivers were included in education sessions. Interventions included distribution of a pamphlet emphasizing the importance of contacting emergency medical services personnel immediately in the event of an overdose, depicting the process for administration of injectable and nasal spray formulations of naloxone, and providing information on other first-response steps. Collaboration with outpatient pharmacies allowed for successful dispensing of naloxone prescriptions. CONCLUSION: The implementation of an outpatient naloxone prescribing policy at a large academic medical center created a streamlined approach for the interprofessional healthcare team to use in providing naloxone education and improved naloxone access to patients at high risk for opioid overdose.
