Treating Benzodiazepine Withdrawal in a Bridge Clinic.

BACKGROUND: Benzodiazepine-involved overdose deaths are rising, driven by increasing use of nonprescribed benzodiazepine pills. For patients who wish to stop nonprescribed benzodiazepine use, rapid inpatient tapers are typically the only option to treat benzodiazepine withdrawal. Substance use disorder bridge clinics can provide the high-touch care needed to manage outpatient benzodiazepine tapers in patients at high risk due to other substance use disorders. OBJECTIVE: Describe the implementation and short-term outcomes of an outpatient benzodiazepine taper protocol to treat benzodiazepine withdrawal in a substance use disorder bridge clinic. METHODS: The clinical team developed a 4- to 6-week intensive outpatient taper protocol using diazepam. Patients with benzodiazepine use disorder were eligible if they had benzodiazepine withdrawal, lacked a prescriber, wanted to stop benzodiazepines completely, and agreed to daily visits. For patients who initiated a taper between April 2021 and December 2022, we evaluated the proportion of patients who completed a taper (i.e., tapered to a last prescribed dose of diazepam 10 mg/d or less); likelihood of remaining on the taper over time; and seizure, overdose, or death documented at the study institution during or within 1 month of taper completion or discontinuation. Other secondary outcomes included HIV testing and prevention, hepatitis C testing, and referrals to recovery coaching or psychiatry. RESULTS: Fifty-four patients initiated a total of 60 benzodiazepine tapers. The population was mostly male (61%) and non-Hispanic White (85%). Nearly all patients had opioid use disorder (96%), and most (80%) were taking methadone or buprenorphine for opioid use disorder before starting the taper. Patients reported using multiple substances in addition to benzodiazepines, most commonly fentanyl (75%), followed by cocaine (41%) and methamphetamine (21%). Fourteen patients (23%) completed a taper with a median duration of 34 days (IQR 27.8-43.5). Most tapers were stopped when the patient was lost to follow-up (57%), or the team recommended inpatient care (18%). Two patients had a seizure, and 4 had a presumed opioid-involved overdose during or within 1 month after the last taper visit, all individuals who did not complete a taper. No deaths occurred during or within 1 month of taper completion or discontinuation. Challenges included frequent loss to follow-up in the setting of other unstable substance use. Patients received other high-priority care during the taper including HIV testing (32%), PrEP initiation (6.7%), hepatitis C testing (30%), and referrals to recovery coaches (18%) and psychiatry (6.7%). CONCLUSIONS: Managing benzodiazepine withdrawal with a 4- to 6-week intensive outpatient taper in patients with benzodiazepine and opioid use disorders is challenging. More work is needed to refine patient selection, balance safety risks with feasibility, and study long-term, patient-centered outcomes.

Novel Uses of Methadone Under the "72-Hour Rule" to Facilitate Transitions of Care and Low-Dose Buprenorphine Induction in an Outpatient Bridge Clinic.

BACKGROUND: Federal regulations restrict methadone for opioid use disorder (OUD) treatment to licensed opioid treatment programs (OTPs). However, providers in other settings can administer methadone for opioid withdrawal under the "72-hour rule" while linking to further care. Prior work has demonstrated that methadone initiation in a low-barrier bridge clinic is associated with high OTP linkage and 1-month retention rates. We describe 2 other novel applications of the 72-hour rule in which methadone withdrawal management facilitated linkage to inpatient hospitalization and outpatient buprenorphine induction. CASE PRESENTATIONS: Patient 1 was a 46-year-old woman with OUD complicated by serious injection-related infections. Severe opioid withdrawal limited her ability to tolerate emergency department wait times and receive inpatient care. We administered methadone for opioid withdrawal in an outpatient bridge clinic immediately before emergency department referral; this enabled hospital admission for intravenous antibiotics and anticoagulation. Patient 2 was a 36-year-old man with OUD desiring buprenorphine treatment. He had been unable to complete traditional buprenorphine induction without experiencing precipitated withdrawal. Thus, we recommended a low-dose buprenorphine induction overlapping with a full opioid agonist. Given the patient's preference to stop using fentanyl immediately, he received 72 hours of methadone for withdrawal treatment during the induction phase and successfully transitioned to buprenorphine without significant concomitant fentanyl use. CONCLUSION: In addition to facilitating OTP linkage, on-demand 72-hour methadone administration for opioid withdrawal can reduce barriers to acute medical care and buprenorphine treatment.

Requirement for Discharge in the Care of a Responsible Adult in Procedural Sedation in the Emergency Department: Necessity or Potential Barrier to Health Equity?

BACKGROUND: Procedural sedation is commonly practiced by emergency physicians to facilitate patient care in the emergency department (ED). Although various guidelines have modernized our approach to procedural sedation, many procedural sedation guidelines and practices still often require that patients be discharged into the care of a responsible adult. DISCUSSION: Such requirement for discharge often cannot be met by underserved and undomiciled patients. Benzodiazepines, opioids, propofol, ketamine, "ketofol," etomidate, and methohexital have all been utilized for procedural sedation in the ED. For patients who may require discharge without the presence of an accompanying responsible adult, ketamine, propofol, methohexital, "ketofol," and etomidate are ideal agents for procedural sedation given rapid onsets, short durations of action, and rapid recovery times in patients without renal or hepatic impairment. Proper pre- and postprocedure protocols should be utilized when performing procedural sedation to ensure patient safety. Through the use of appropriate medications and observation protocols, patients can safely be discharged 2 to 4 h postprocedure. CONCLUSION: There is no pharmacodynamic or pharmacokinetic basis to require discharge in the care of a responsible adult after procedural sedation. Thoughtful medication selection and the use of evidence-based pre- and postprocedure protocols in the ED can help circumvent this requirement, which likely disproportionally impacts patients who are of low socioeconomic status or undomiciled.

HIV Exposure Prophylaxis Delivery in a Low-barrier Substance Use Disorder Bridge Clinic during a Local HIV Outbreak at the Onset of the COVID-19 Pandemic.

OBJECTIVES: People who inject drugs (PWID) may experience high human immunodeficiency virus (HIV) risk and inadequate access to biomedical HIV prevention. Emerging data support integrating HIV post-exposure and pre-exposure prophylaxis (PEP, PrEP) into services already accessed by PWID. We describe PEP/PrEP eligibility and receipt in a low-barrier substance use disorder bridge clinic located in an area experiencing an HIV outbreak among PWID at the onset of the COVID-19 pandemic. METHODS: Retrospective chart review of new patients at a substance use disorder bridge clinic in Boston, MA (January 15, 2020-May 15, 2020) to determine rates of PEP/PrEP eligibility and prescribing. RESULTS: Among 204 unique HIV-negative patients, 85.7% were assessed for injection-related and 23.0% for sexual HIV risk behaviors. Overall, 55/204 (27.0%) met CDC criteria for HIV exposure prophylaxis, including 7/204 (3.4%) for PEP and 48/204 (23.5%) for PrEP. Four of 7 PEP-eligible patients were offered PEP and all 4 were prescribed PEP. Thirty-two of 48 PrEP eligible patients were offered PrEP, and 7/48 (14.6%) were prescribed PrEP. Additionally, 6 PWID were offered PrEP who lacked formal CDC criteria. CONCLUSIONS: Bridge clinics patients have high rates of PEP/PrEP eligibility. The majority of patients with identified eligibility were offered PEP/PrEP, suggesting that upstream interventions that increase HIV risk assessment may support programs in initiating PEP/PrEP care. Additional work is needed to understand why patients declined PEP/PrEP. PrEP offers to PWID who did not meet CDC criteria also suggested provider concern regarding the sensitivity of CDC criteria among PWID. Overall, bridge clinics offer a potential opportunity to increase biomedical HIV prevention service delivery.

Bridge clinic implementation of "72-hour rule" methadone for opioid withdrawal management: Impact on opioid treatment program linkage and retention in care.

BACKGROUND: Methadone for opioid use disorder (OUD) treatment is restricted to licensed opioid treatment programs (OTPs) with substantial barriers to entry. Underutilized regulations allow non-OTP providers to administer methadone for opioid withdrawal for up to 72 h while arranging ongoing care. Our low-barrier bridge clinic implemented a new pathway to treat opioid withdrawal and facilitate OTP linkage utilizing the "72-hour rule." METHODS: Patients presenting to a hospital-based bridge clinic were evaluated for OUD, opioid withdrawal, and treatment goals. Eligible patients were offered methadone opioid withdrawal management with rapid OTP referral. OTPs accepted patients as direct admissions. We described bridge clinic patients who received at least one dose of methadone between March-August 2021 and key clinical outcomes including OTP referral completion within 72 h. For the subset of patients referred to our two primary OTP partners, we described OTP linkage (i.e., attended at least one OTP visit within one month) and OTP retention at one month. RESULTS: Methadone was administered during 150 episodes of care for 142 unique patients, the majority of whom were male (73%), white (67%), and used fentanyl (85%). In 92% of episodes (138/150), a plan for ongoing care was in place within 72 h. Among 121 referrals to two primary OTP partners, 87% (105/121) linked and 58% (70/121) were retained at one month. CONCLUSIONS: Methadone administration for opioid withdrawal with direct OTP admission under the "72-hour rule" is feasible in an outpatient bridge clinic and resulted in high OTP linkage and 1-month retention rates. This model has the potential to improve methadone access.

Gender inequality in PGY1 residency leadership positions and conferral of health-system pharmacy professional awards.

PURPOSE: To address gender inequality, the American Society of Health-System Pharmacists (ASHP) created a steering committee that recommended the collection of baseline and ongoing metrics of pharmacy leadership. The purpose of this study was to quantify gender inequality in distributions of residency program director (RPD) and director of pharmacy (DOP) positions and to investigate gender distributions among recipients of ASHP professional leadership awards. METHODS: RPD and DOP information for postgraduate year 1 (PGY1) programs included in the online ASHP residency directory were collected in December of 2020. Publicly available records were used to collect information on recipients of the Harvey A.K. Whitney Award and John W. Webb Award during the periods 1950-2020 and 1985-2020, respectively. Gender information for RPDs, DOPs, and award recipients was collected from listed pronouns available in public records. A χ 2 test was used for analysis of the collected data. RESULTS: A total of 1,176 PGY1 residency programs were included. Of the RPD positions assessed, 66% (n = 775) were filled by women pharmacists (P < 0.0001), while the percentage of DOP leadership positions held by women was 42% (n = 496) (P < 0.0001). Evaluation of data on recipients of the Harvey A.K. Whitney Award and John W. Webb Award revealed the occurrence of female recipients is 19.7% (n = 14) and 16.7% (n = 6), respectively (P < 0.0001). CONCLUSION: RPD positions have a higher prevalence of being filled by women. DOP positions remain male-dominated and revealed gender inequality among senior-level leadership roles. Pharmacy leadership award analysis identified further gender inequality. The results from the study serve as a baseline of current gender metrics for pharmacy leaderships in hospital systems with PGY1 residency programs.

Hyperglycemia Management Prior to Admission in an Urban Emergency Department.

BACKGROUND AND OBJECTIVES: The aim of this quality improvement project was to decrease the percentage of emergency department (ED) patients admitted with blood glucose (BG) level above 250 mg/dL to less than 20%. METHODS: A work group comprised physicians, pharmacists, and endocrinologists collaborated to standardize management of ED hyperglycemia. Plan-Do-Study-Act cycles included education, monitoring of patients with BG level above 200 mg/dL, and development of an ED-specific insulin protocol. RESULTS: Following the initiative, 24.8% fewer patients were admitted with BG level above 250 mg/dL. The average admission BG level was reduced by 65.8 mg/dL, creating a significant shift toward improved average BG level. No difference was seen in hospital mortality, hospital length of stay, ED length of stay, hypoglycemia, or inhospital diabetic ketoacidosis or hyperglycemic hyperosmolar syndrome. CONCLUSION: Implementation of a standardized hyperglycemia treatment protocol along with pharmacist interventions reduced average admission BG and the percentage of patients with BG level above 250 mg/dL on admission.

Presence of "One Pill Can Kill" Medications in Medication Organizers: Implications for Child Safety.

BACKGROUND: Medication organizers increased compliance, but they do not contain child protective packaging. Medications organizers have been involved in some pediatric exposures; however, previous reports do not describe if "one pill can kill" (1PCK) medications were involved in the exposures. 1PCK medications may cause toxicity even with a single tablet. OBJECTIVE: The purpose of this study is to describe the type and presence of 1PCK medications dispensed in medication organizers at a single center. METHODS: Adult patients who received blister packed medications from September 1, 2017 to September 30, 2017 were included in this retrospective review. Medications were excluded if dispensed traditionally during this time. The primary outcome described included 1PCK medications (quantity and type). Secondary outcomes included total number of tablets dispensed, delayed- (DR) and extended-release (ER) formulations, average age of those dispensed 1PCK medications versus those without. RESULTS: A total of 450 patients received 486 blister packs and 75.5% of which found to include 1PCK medications. Most commonly included 1PCK medications were beta-blockers and calcium channel blockers (42.4 and 49.4%, respectively). Patients receiving 1PCK medications were older (69.1 ± 12.6 vs 62.6 ± 16.7 years old, p < 0.0001) and included more medications (8.5 ± 2.9 vs 5.7 ± 2.9 medications, p < 0.0001). DR and ER formulations were in 150 packs. CONCLUSION: The majority of dispensed medication organizers included 1PCK medications. Upon dispensing, patients should be questioned for possible proximity exposures. Additionally, they should receive education on medication safety for children that may be in proximity of the medications during home, work, or social activities.

Operationalizing influenza vaccination in an urban safety-net emergency department.

INTRODUCTION: Influenza vaccination is a recommended tool in preventing influenza-related illnesses, medical visits, and hospitalizations. With many patients remaining unvaccinated each year, the Emergency Department (ED) represents a unique opportunity to provide vaccinations to patient not yet vaccinated. However, busy urban safety-net EDs maybe challenged to safely execute such a vaccination program. The aim of this quality improvement project was to assess influenza vaccination feasibility in the ED and improve influenza vaccination rates in our community. METHODS: The quality improvement work-group, comprised of ED physicians, nurses, and pharmacists, designed and implemented an influenza vaccination protocol that aligned with the ED workflow. The outcome measure was the total number of patients vaccinated per month and per influenza season. Process measures included the type of influenza vaccine administered and type of care area within ED. Balancing measures were also included. RESULTS: Following the initiative, a total of 337 patients received influenza vaccinations in the ED between September 1, 2018 and December 31, 2020 compared to none during the previous influenza season. With each influenza season, the number of vaccinated patients increased from 61 to 134 and 142, respectively. The average age of the patients was 48.23 ± 15.29, 52.89 ± 15.91, and 44.92 ± 18.97 years old. Most patients received the vaccination while roomed in the high acuity section of the adult ED. No adverse effects or automated dispensing cabinet stockouts were observed. CONCLUSION: Our structured program indicates that influenza vaccine administration to eligible patients is feasible in a busy urban safety-net ED. Piloting new and further developing existing ED-based influenza vaccination programs have the potential to significantly benefit public health.

Methadone initiation in a bridge clinic for opioid withdrawal and opioid treatment program linkage: a case report applying the 72-hour rule.

BACKGROUND: In the United States, methadone for opioid use disorder (OUD) is limited to highly regulated opioid treatment programs (OTPs), rendering it inaccessible to many patients. The "72-hour rule" allows non-OTP providers to administer methadone for emergency opioid withdrawal management while arranging ongoing care. Low-barrier substance use disorder (SUD) bridge clinics provide rapid access to buprenorphine but offer an opportunity to treat acute opioid withdrawal while facilitating OTP linkage. We describe the case of a patient with OUD who received methadone for opioid withdrawal in a bridge clinic and linked to an OTP within 72 h. CASE PRESENTATION: A 54-year-old woman with severe OUD was seen in a SUD bridge clinic requesting OTP linkage and assessed with a clinical opiate withdrawal scale (COWS) score of 12. She reported daily nasal use of 1 g heroin/fentanyl. Prior OUD treatment included buprenorphine-naloxone, which was only partially effective. Her acute opioid withdrawal was treated with a single observed oral dose of methadone 20 mg. She returned the following day with persistent opioid withdrawal (COWS score 11) and was treated with methadone 40 mg. On day 3, the patient was successfully admitted to a local OTP, where she remained engaged 3 months later. CONCLUSIONS: While patients continue to face substantial access barriers, bridge clinics can play an important role in treating opioid withdrawal, building partnerships with OTPs to initiate methadone on demand, and preventing life-threatening delays to methadone treatment. Federal policy reform is urgently needed to make methadone more accessible to people with OUD.

A Comparison of Etomidate, Ketamine, and Methohexital in Emergency Department Rapid Sequence Intubation.

BACKGROUND: Rapid sequence intubation (RSI) is routinely used for emergent airway management in the emergency department (ED). It involves the use of induction, and paralytic agents help facilitate endotracheal tube placement. OBJECTIVE: In response to a previous national drug shortage resulting in the use of alternative induction agents for RSI, we describe the effectiveness and safety of ED RSI with ketamine or methohexital compared with etomidate. METHODS: We conducted a retrospective, single-center observational study from March 1-August 31, 2012 describing RSI with etomidate, ketamine, and methohexital. All adult patients undergoing RSI in the ED who received etomidate prior to its shortage and methohexital or ketamine during the shortage were included. RESULTS: The study included 47, 9, and 26 patients in the etomidate, ketamine, and methohexital groups, respectively. Successful intubation on the first attempt occurred in 74.5%, 55.6%, and 73.1% of the etomidate, ketamine, and methohexital groups, respectively. The mean number of intubation attempts and time to intubation seemed to be similar in all groups. At least three intubation attempts were required in 22.2% and 7.7% of the ketamine and methohexital groups, respectively, compared with none in the etomidate group. Two aspirations were observed in the etomidate group. CONCLUSION: Methohexital and etomidate had similar rates of successful intubation on the first attempt and seem to be more effective than ketamine. Etomidate may reduce the need for three or more intubation attempts. Larger, prospective studies are needed to determine if ketamine or methohexital are more effective than etomidate for RSI.

Hikers poisoned: Veratrum steroidal alkaloid toxicity following ingestion of foraged Veratrum parviflorum.

INTRODUCTION: Steroidal alkaloids are found in plants of the genus Veratrum. Their toxicity manifests as gastrointestinal symptoms followed by a Bezold-Jarisch reflex: hypopnea, hypotension, and bradycardia. Some Veratrum steroidal alkaloids are also teratogens interfering with the hedgehog-2 signaling pathway, which causes cyclopsia and holoprosencephaly. We present a case of accidental poisoning from Veratrum parviflorum mistaken for the edible Allium tricoccum (ramps, wild leek). CASE HISTORY: A 27-year-old man and his 25-year-old wife presented to the emergency department with nausea, vomiting, hypotension, and bradycardia after foraging and ingesting plants that they believed to be a local native species of wild leek. METHODS: We collected and analyzed the implicated fresh plant material and both patients' serum/plasma. We used liquid chromatography-mass spectroscopy and high-resolution electrospray ionization time of flight tandem mass spectrometry to extract and characterize steroidal alkaloids from the foraged plant and patients' serum. RESULTS: Our V. parviflorum samples contained verazine, veratramine, veratridine, and cyclopamine. DISCUSSION: Steroidal alkaloids have been previously isolated from Veratrum viride and Veratrum album and toxicity has been reported mainly from V. album species. CONCLUSION: V. parviflorum toxicity manifests with gastrointestinal and cardiac symptoms. Treatment is symptomatic and supportive as with previous case reports of toxicity with other Veratrum species.

Postoperative Anticholinergic Poisoning: Concealed Complications of a Commonly Used Medication.

BACKGROUND: Scopolamine is a potent anticholinergic compound used commonly for the prevention of postoperative nausea and vomiting. Scopolamine can cause atypical anticholinergic syndromes due to its prominent central antimuscarinic effects. CASE REPORT: A 47-year-old female presented to the emergency department (ED) 20 h after hospital discharge for a right-knee meniscectomy, with altered mental status (AMS) and dystonic extremity movements that began 12 h after her procedure. Her vital signs were normal and physical examination revealed mydriasis, visual hallucinations, hyperreflexia, and dystonic movements. Laboratory data, lumbar puncture, and computed tomography were unrevealing. The sustained AMS prompted a re-evaluation that revealed urinary overflow with 500 mL of retained urine discovered on ultrasound and a scopolamine patch hidden behind her ear. Her mental status improved shortly after patch removal and physostigmine, with complete resolution after 24 h with discharge diagnosis of scopolamine-induced anticholinergic toxicity. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although therapeutically dosed scopolamine transdermal patches rarely cause complications, incomplete toxidromes can be insidiously common in polypharmacy settings. Providers should thoroughly evaluate the skin of intoxicated patients for additional adherent medications that may result in a delay in ED diagnosis and curative therapies. Our case, as well as rare case reports of therapeutic scopolamine-induced anticholinergic toxicity, demonstrates that peripheral anticholinergic effects, such as tachycardia, dry mucous membranes, and hyperpyrexia are often not present, and incremental doses of physostigmine may be required to reverse scopolamine's long duration of action. This further complicates identification of the anticholinergic toxidrome and diagnosis.

Addition of tranexamic acid to a traumatic injury massive transfusion protocol.

PURPOSE: The development of eligibility criteria and use of tranexamic acid in conjunction with a massive transfusion protocol (MTP) are described. SUMMARY: The trauma surgery and pharmacy departments collaborated to operationalize tranexamic acid administration in trauma patients for whom an MTP was activated. The MTP at Boston Medical Center, an urban, tertiary, academic medical center, is activated by the attending physician when the patient is expected to require at least 10 units of packed red blood cells in 24 hours. Tranexamic acid was considered in MTP trauma patients who arrived at the medical center within 8 hours of traumatic injury, were 15 years of age or older, and weighed at least 40 kg. Eligible patients were to receive a loading dose of tranexamic acid 1 g i.v. over 10 minutes followed by a maintenance dose of 1 g infused over 8 hours. To ensure that tranexamic acid use was limited to trauma patients, both its location of use and physician-ordering privileges were restricted by the pharmacy department. A 16-month assessment revealed that 16 patients received tranexamic acid, 13 (81%) of whom met all criteria for use. Tranexamic acid was used in 13 (38%) of 34 eligible MTP patients. Barriers to the use of tranexamic acid include a lack of familiarity with the medication among staff, drug availability, the complexity of administration, and the critical setting of MTP activation. CONCLUSION: Multidisciplinary collaboration and standardization of tranexamic acid use in conjunction with an MTP promoted use of the drug within a trauma population.

Cost-effectiveness of fulvestrant 250 mg versus 500 mg in postmenopausal women with estrogen receptor-positive metastatic breast cancer and disease progression after antiestrogen therapy.

PURPOSE: To determine the cost-effectiveness of fulvestrant 250 mg compared to 500 mg in postmenopausal women with estrogen receptor-positive metastatic breast cancer and disease progression after antiestrogen therapy. METHODS: A Markov model was constructed to find the incremental cost-effectiveness of fulvestrant 250 mg monthly when compared with the 500 mg monthly in patients with progression after antiestrogen therapy. The model duration was 24 months. Clinical efficacy data inputs were derived from a phase III clinical trial demonstrating a statistically significant increase in progression-free survival in patients receiving 500 mg versus 250 mg. Cost data utilized were all relevant Ambulatory Payment Classification payment rates from the 2011 Medicare Outpatient Prospective Payment System. A Monte Carlo simulation was performed to test the model at various willingness to pay thresholds. RESULTS: The incremental cost-effectiveness ratio as determined by the Markov model was US$10,972 per month of progression-free survival for the 500 mg dose compared with the 250 mg dose. Using a Monte Carlo simulation, it was found that 500 mg monthly was cost-effective at and above the willingness to pay threshold of US$15,000 per month. A series of one-way sensitivity analyses showed this result is robust to geographical practice variations in costs of drug administration and physician examination. CONCLUSION: From a third party payer perspective, the value of fulvestrant 500 mg monthly is dependent on the willingness to pay threshold. Despite a labeling change for fulvestrant in September 2010, fulvestrant 250 mg monthly appears to be a viable option in the target population.
