Eliminating the benzos: A benzodiazepine-sparing approach to preventing and treating alcohol withdrawal syndrome.

BACKGROUND: Alcohol withdrawal syndrome (AWS) represents significant cost to the hospitalized trauma population from a clinical and financial perspective. Historically, AWS has been managed with benzodiazepines. Despite their efficacy, benzodiazepines carry a heavy adverse effect profile. Recently, benzodiazepine-sparing protocols for the prophylaxis and treatment of AWS have been used in medical patient populations. Most existing benzodiazepine-sparing protocols use phenobarbital, while ours primarily uses gabapentin and clonidine, and no such protocol has been developed and examined for safety and efficacy specifically within a trauma population. METHODS: In December of 2019, we implemented our benzodiazepine-sparing protocol for trauma patients identified at risk for alcohol withdrawal on admission. Trauma patients at risk for AWS admitted to an academic Level 1 trauma center before (conventional) and after (benzodiazepine-sparing [BS]) protocol implementation were compared. Outcomes examined include morphine milligram equivalent dosing rates and lorazepam equivalent dosing rates as well as the Clinical Institute Withdrawal Assessment for Alcohol, revised (CIWA-Ar) scores, hospital length of stay, intensive care unit length of stay, and ventilator days. RESULTS: A total of 387 conventional and 134 benzodiazepine sparing patients were compared. Injury Severity Score (13 vs. 16, p = 0.10) and admission alcohol levels (99 vs. 149, p = 0.06) were similar. Patients in the BS pathway had a lower maximum daily CIWA-Ar (2.7 vs. 1.5, p = 0.04). While mean morphine milligram equivalent per day was not different between groups (31.5 vs. 33.6, p = 0.49), mean lorazepam equivalents per day was significantly lower in the BS group (1.1 vs. 0.2, p < 0.01). Length of stay and vent days were not different between the groups. CONCLUSION: Implementation of a benzodiazepine-sparing pathway that uses primarily clonidine and gabapentin to prevent and treat alcohol withdrawal syndrome in trauma patients is safe, reduces the daily maximum CIWA-Ar, and significantly decreases the need for benzodiazepines. Future studies will focus on outcomes affected by avoiding AWS and benzodiazepines in the trauma population. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level IV.

Evaluation of phenobarbital for prevention of alcohol withdrawal in trauma patients.

BACKGROUND: Up to 30% of trauma patients experience alcohol withdrawal syndrome (AWS) during their hospital admission, which is associated with worse outcomes. While benzodiazepines and phenobarbital are the mainstay of AWS management, there are limited data on the prevention of AWS. The objective was to evaluate the safety and efficacy of phenobarbital for the prevention of AWS. METHODS: Adult patients admitted to a level 1 trauma center who received at least one dose of phenobarbital for the prevention of AWS between January 2019 and August 2021 were included. Patients were case matched to a control group managed with symptom-triggered therapy based on risk of AWS. Risk factors included sex, age, history of AWS/delirium tremens or withdrawal seizures, selected laboratory values, and screening questionnaires. The primary endpoint was the need for rescue therapy. Secondary endpoints included the time to rescue therapy, intensive care unit (ICU) length of stay (LOS), and hospital LOS. RESULTS: Overall, 110 patients were included with 55 patients in each group. The phenobarbital group had higher baseline Injury Severity Scores ( p = 0.03) and were more likely to be admitted to the ICU (44% vs. 24%; p = 0.03). The phenobarbital group required less rescue therapy (16% vs. 62%; p < 0.001) with a longer time to rescue therapy administration (26 vs. 11 hours; p = 0.01). The phenobarbital group had a longer hospital LOS (216 vs. 87 hours; p = 0.0001) but no difference in ICU LOS ( p = 0.36). There was no incidence of delirium tremens or seizures and no difference in intubation rates ( p = 0.68). There was no incidence of hypotension associated with phenobarbital. CONCLUSION: Patients managed with phenobarbital had a lower need for rescue therapy for AWS with no increased adverse effects. Further studies should evaluate a protocol to prevent alcohol withdrawal in the trauma population. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

Implementation of an algorithm for tapering analgosedation reduces iatrogenic withdrawal syndrome in pediatric intensive care.

BACKGROUND: Proper analgosedation is a cornerstone in the treatment of critically ill patients in Pediatric Intensive Care Units (PICUs). Medications, such as fentanyl, morphine, and midazolam, are essential to safe and respectful care. The use of these medications over time may lead to side effects such as iatrogenic withdrawal syndrome (IWS) in the tapering phase. The aim of the study was to test an algorithm for tapering analgosedation to reduce the prevalence of IWS in two Norwegian PICUs at Oslo University Hospital. METHODS: A cohort of mechanically ventilated patients from newborn to 18 years with continuous infusions of opioids and benzodiazepines for 5 days or more were included consecutively from May 2016 to December 2021. A pre- and posttest design, with an intervention phase using an algorithm for tapering analgosedation after the pretest, was used. The ICU staffs were trained in using the algorithm after the pretest. The primary outcome was a reduction in IWS. The Withdrawal Assessment Tool-1 (WAT-1) was used to identify IWS. A WAT-1 score ≥3 indicates IWS. RESULTS: We included 80 children, 40 in the baseline group, and 40 in the intervention group. Age and diagnosis did not differ between the groups. The prevalence of IWS was 95% versus 52.5% in the baseline group versus the intervention group, and the peak WAT-1 median was 5.0 (IQR 4-6.8) versus 3.0 (IQR 2.0-6.0) (p = .012). Based on SUM WAT-1 ≥ 3, which describes the burden over time better, we demonstrated a reduction of IWS, from a median of 15.5 (IQR 8.25-39) to a median of 3 (IQR 0-20) (p = <.001). CONCLUSION: We suggest using an algorithm for tapering analgosedation in PICUs since the prevalence of IWS was significantly lower in the intervention group in our study.

An innovative inpatient protocol for alcohol withdrawal prevention in a 16-year-old adolescent: a case report.

BACKGROUND: Alcohol cessation in youth with daily drinking poses a risk of severe and life-threatening alcohol withdrawal. If unsupervised, alcohol withdrawal in heavy users can cause severe complications, such as seizures, delirium tremens, and death. We present the case of a teenager admitted at our pediatric center for the prevention of alcohol withdrawal using an innovative protocol, including a fixed-dosage benzodiazepine regimen. CASE DESCRIPTION: A 16-year-old Caucasian male, known to have anxiety and an attention deficit disorder, was electively admitted for medical stabilization and surveillance of alcohol withdrawal. He had been previously diagnosed with alcohol use disorder and had a past history of withdrawal symptoms. He was prescribed a course of thiamine, folic acid, as well as a fixed-dosage benzodiazepine taper over 5 days. His withdrawal symptoms were evaluated using a standardized Clinical Institute Withdrawal Assessment for Alcohol scale. During his stay, he reported minimal symptoms, as well as a score on the Clinical Institute Withdrawal Assessment for Alcohol scale consistently lower than 5. His mood, motivation, eating habits and sleeping patterns significantly improved during his stay. He developed no medical complications and demonstrated pride in his successes. He was successfully transferred to a long-term rehabilitation center. CONCLUSIONS: A withdrawal prevention protocol was developed on the basis of existing literature. It included a soothing environment, basic laboratory work evaluating the medical complications of alcohol use, as well as medication aiming to prevent and reduce potential withdrawal symptoms. The patient responded well to the fixed-dosage taper with minimal symptoms and discomfort. Although alcohol use in adolescents is frequent, alcohol withdrawal in this population is rarely seen in a pediatric hospital setting. Nonetheless, given the lack of existing guidelines regarding alcohol withdrawal in adolescents, standardized protocols could be greatly beneficial for the prevention of this condition in this population.

Omega-3 fatty acids prevent nicotine withdrawal-induced exacerbation of anxiety and depression by affecting oxidative stress balance, inflammatory response, BDNF and serotonin metabolism in rats.

Adolescents are known to be more vulnerable than adults to the adverse effects of nicotine dependence. In the present study, we aimed to investigate whether adolescent nicotine exposure, followed by a period of abstinence, could affect the anxiety- and depressive-like behaviors in rats. For this purpose, behavioral assessments were carried out using open field test, elevated plus maze and forced swimming test in male rats received chronic nicotine intake during adolescence followed by a period of abstinence in adulthood, compared to their control counterparts. In addition, O3 pre-treatment was done at three different doses to reveal whether it could prevent nicotine withdrawal effects. Then, animals were euthanized and the cortical concentrations of oxidative stress markers, inflammatory indices, brain-derived neurotrophic factor, serotonin and the enzymatic activity of monoamine oxidase-A were measured. Results indicated that nicotine withdrawal exacerbates the behavioral signs of anxiety through alteration of the brain oxidative stress balance, inflammatory response and serotonin metabolism. Moreover, we found that omega 3 pre-treatment significantly prevents the nicotine withdrawal-induced complications by restoration of changes in the mentioned biochemical indices. Moreover, the improving effects of O3 fatty acids were found to be dose-dependent in all experiments. Taken together, we would like to suggest the O3 fatty acids supplementation as a safe, inexpensive and effective strategy for prevention or amelioration of detrimental effects induced by nicotine withdrawal at cellular and behavioral levels.

Antidepressant Tapering Is Not Routine But Could Be.

INTRODUCTION: When antidepressants are discontinued, severe withdrawal symptoms are possible. Some patients have few or no problems stopping, whereas others struggle. That struggle can be minimized or prevented with careful dose tapering. How often is that done? METHODS: Using 7 years of medical records, we determined the percentage of patients who received a prescription for the lowest available dose of their antidepressant before it was discontinued, as an indicator of a deliberate taper. RESULTS: Over that period, 8.9% of patients had evidence of tapering. The percentage increased from 4.9% in 2014 to a plateau around 10% in the past 4 years. DISCUSSION: While reports of severe withdrawal are increasingly recognized and must be addressed, our data suggest that many patients can discontinue their antidepressants without a taper through the lowest dose. However, it is difficult to identify which patients will struggle without a careful taper. A "one-size-fits-all" taper approach is recommended, balancing the need for withdrawal prevention with the need to avoid unnecessary complexity for the majority of patients. The first decrement is key for all patients: it must go well. Thereafter many patients may accelerate but all should receive a prescription for the lowest available dose of their antidepressant.

OBJECTIVES: To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning. METHODS: A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning. RESULTS: There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01). CONCLUSIONS: Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

Buprenorphine precipitated opioid withdrawal: Prevention and management in the ED setting.

INTRODUCTION: Buprenorphine precipitated opioid withdrawal (BPOW) is an uncommon complication of buprenorphine initiation in the emergency department (ED), but it can produce significant discomfort and be distressing to patients. As EDs continue to care for those with opioid use disorder (OUD), clinicians should be aware of how to prevent and treat BPOW. OBJECTIVE: This narrative review provides an evidence-based update of the epidemiology, prevention strategies, and management of BPOW for the emergency clinician. DISCUSSION: BPOW is a rapid worsening of opioid withdrawal symptoms upon initiating buprenorphine. BPOW can be prevented by waiting for the onset of moderate Clinical Opioid Withdrawal Scale (COWS) > 13 opioid withdrawal symptoms and a sufficient amount of time since last full opioid agonist use before buprenorphine administration. Risk factors for BPOW include chronic fentanyl use, methadone use, and concurrent benzodiazepine use. Alternative dosing strategies such as low-dose or "microdosing" and high-dose or "macrodosing" are options for buprenorphine that may impact the development of BPOW. The strategy of treating BPOW with more buprenorphine has a pharmacological basis and has been effective in case reports. Additional management is symptom-based and supportive. Although most cases have a benign course, patients may be significantly less likely to use buprenorphine for OUD in the future or seek care for substance use disorder. CONCLUSIONS: Appropriate initiation of buprenorphine is important to prevent BPOW. Dosing buprenorphine should be based on the patient's patterns of opioid use and response to therapy. Management of BPOW should be symptom-based but include additional buprenorphine and adjunctive medications.

Minor effect of patient education for alcohol cessation intervention on outcomes after acute fracture surgery: a randomized trial of 70 patients.

BACKGROUND AND PURPOSE: High alcohol intake is associated with increased risk of postoperative complications. Alcohol cessation intervention is recommended prior to elective surgery. We investigated short- and long-term effects of perioperative intensive alcohol intervention in relation to acute ankle fracture surgery. PATIENTS AND METHODS: 70 patients requiring ankle fracture surgery and consuming ≥ 21 drinks weekly (1 drink = 12 g ethanol) were randomized to a manual-based 6-week intensive standardized alcohol cessation program, the Gold Standard Program (GSP-A), or treatment as usual (TAU), on the day of operation. GSP-A included 5 personal meetings, patient education, and motivational and pharmacological support (alcohol withdrawal prophylaxis, B vitamins, and low-dose disulfiram). Complications requiring treatment were measured after 6 weeks and 1 year. Alcohol intake was validated by biomarkers. Quality of life (QoL) was measured by the SF-36. Hospital costs were obtained from the National Hospital Costs Register. RESULTS: Postoperatively, complete alcohol cessation was higher in the GSP-A than in the TAU group (18/35 vs. 5/35, number needed to treat = 3, p ≤ 0.001), but not lowrisk consumption in the long term (10/35 vs. 7/33, p = 0.5). Number of complications in the short and long term (12/35 vs. 14/33, 16/35 vs. 18/33), the SF-36 score, or hospital costs in the short and long term (€6,294 vs. €8,024, €10,662 vs. €12,198), were similar between the groups. INTERPRETATION: Despite an effect on alcohol cessation and a positive tendency as regards the other outcomes, the postoperative complications, QoL, and costs were similar. Better perioperative strategies for acute surgical patients with high alcohol intake therefore need to be developed.

Strategies for the management and prevention of withdrawal syndrome in critically ill pediatric patients: a systematic review. / Estratégias para manejo e prevenção da síndrome de abstinência em pacientes pediátricos críticos: revisão sistemática.

OBJECTIVE: To verify strategies for the prevention and treatment of abstinence syndrome in a pediatric intensive care unit. METHODS: This is a systematic review in the PubMed database®, Lilacs, Embase, Web of Science, Cochrane, Cinahl, Cochrane Database Systematic Review and CENTRAL. A three-step search strategy was used for this review, and the protocol was approved in PROSPERO (CRD42021274670). RESULTS: Twelve articles were included in the analysis. There was great heterogeneity among the studies included, especially regarding the therapeutic regimens used for sedation and analgesia. Midazolam doses ranged from 0.05mg/kg/hour to 0.3mg/kg/hour. Morphine also varied considerably, from 10mcg/kg/hour to 30mcg/kg/hour, between studies. Among the 12 selected studies, the most commonly used scale for the identification of withdrawal symptoms was the Sophia Observational Withdrawal Symptoms Scale. In three studies, there was a statistically significant difference in the prevention and management of the withdrawal syndrome due to the implementation of different protocols (p < 0.01 and p < 0.001). CONCLUSION: There was great variation in the sedoanalgesia regimen used by the studies and the method of weaning and evaluation of withdrawal syndrome. More studies are needed to provide more robust evidence about the most appropriate treatment for the prevention and reduction of withdrawal signs and symptoms in critically ill children.

Dexmedetomidine for prevention of opioid/benzodiazepine withdrawal syndrome in pediatric intensive care unit: Interim analysis of a randomized controlled trial.

STUDY OBJECTIVE: Withdrawal syndrome (WS) may be a critical drawback of opioid/benzodiazepine weaning in children. The most effective intervention to reduce WS prevalence is yet to be determined. Dexmedetomidine (DEX) was estimated to be effective in reducing WS-related symptoms, but no randomized trial has been conducted to prove its efficacy so far. We aimed to evaluate the efficacy and safety of DEX in reducing the occurrence of WS. DESIGN AND SETTING: This was an adaptive randomized double-blind placebo-controlled trial conducted at three Italian Pediatric Intensive Care Units (PICUs). PATIENTS: It included children admitted to PICU, undergoing at least five days of opioids/benzodiazepines continuous infusion, and ready to start the analgosedation weaning. INTERVENTION: Twenty-four hours before the start of weaning, an infusion of DEX/placebo was started. WS symptoms were monitored using the Withdrawal-Assessment-Tool-version-1 (WAT-1). In case of WS symptoms (WAT-1 ≥ 3) an opioid/benzodiazepine bolus was given and the DEX/placebo infusion-rate was increased. MEASUREMENTS: The primary outcome measure was the prevalence of WS. Secondary outcomes were the trend of WAT-1 over time, number of rescue doses, length of weaning and PICU-stay, and onset of adverse events (AEs). MAIN RESULTS: Forty-five patients were enrolled, of whom 5 dropped-out and 40 entered the interim analysis. There were no significant baseline differences between groups. WS prevalence did not significantly differ between groups (77.8% DEX vs 90.9% placebo, p = 0.381). By generalized linear mixed modeling, the WAT-1 trend showed a significant increase per unit of time in the DEX arm (estimate 0.27, CI 0.07-0.47, p = 0.009) compared to placebo. Most frequent AEs were hemodynamic, and all of them happened in the DEX arm. CONCLUSIONS: A continuous infusion of DEX, started 24 h before the analgosedation weaning and increased based on WS signs, was not able to significantly modify the prevalence of WS in children who received at least five days of opioids/benzodiazepines treatment compared to placebo.

Benzodiazepines and Related Sedatives.

Benzodiazepine and related sedative use has been increasing. There has been a growing number of unregulated novel psychoactive substances, including designer benzodiazepines. Benzodiazepines have neurobiological and pharmacologic properties that result in a high potential for misuse and physical dependence. Options for discontinuing long-term benzodiazepine use include an outpatient benzodiazepine taper or inpatient withdrawal management at a hospital or detoxification facility. The quality of evidence on medications for benzodiazepine discontinuation is overall low, whereas cognitive behavioral therapy has shown the most benefit in terms of behavioral treatments. Benzodiazepines may also have significant adverse effects, increasing the risk of overdose and death.

Delayed crises following benzodiazepine withdrawal: deficient adaptive mechanisms or simple pharmacokinetics? Detoxification assisted by serum-benzodiazepine elimination tracking.

OBJECTIVE: Rapid relapses after successful withdrawal occur even in apparently motivated benzodiazepine (BZD)-dependent patients. Regardless of known personality or biological (re-adaptation) issues, the aim of this open-label, single-arm, seminaturalistic study was to search for any detoxification errors contributing to failures. METHODS: The data came from 350 inpatients. Based on serum-BZD evolution criteria, the procedure was divided into four stages: substitution, accumulation, elimination and post-elimination observation. After switching the patients to a long-acting substitute (diazepam), to prevent data falsification due to unwanted overaccumulation, the doses were expeditiously reduced under laboratory feedback until accumulation stopped. With the start of effective elimination, the tapering rate slowed and was individually adjusted to the patient's current clinical state. The tracking of both serum-BZD concentration and the corresponding intensity of withdrawal symptoms was continued throughout the entire elimination phase, also following successful drug withdrawal. Detoxification was concluded only after the patient's post-elimination stabilization. RESULTS: Regardless of various initial serum-BZD concentration levels and the customized dose-reduction rate, and despite the novel lab-driven actions preventing initial overaccumulation, elimination was systematically proven to be protracted and varied within the 2- to 95-day range after the final dose. Within this period, withdrawal syndrome culminated several times, with varying combinations of symptoms. The last crisis occurrence (typically 2-3 weeks after withdrawal) correlated with the final serum-BZD elimination. The factors that prolonged elimination and delayed the final crisis were patient age, duration of addiction, adjunct valproate medication and elimination stage start parameters growing with former overaccumulation. CONCLUSIONS: The low-concentration detoxification stage is critical for patients' confrontations with recurring withdrawal symptoms. Underestimated elimination time following drug withdrawal and premature conclusions of detoxification expose patients to unassisted withdrawal crises. Concentration tracking defines proper limits for medical assistance, preventing early relapses.

Reducing the Risk of Withdrawal Symptoms and Relapse Following Clozapine Discontinuation-Is It Feasible to Develop Evidence-Based Guidelines?

Clozapine is the only antipsychotic that is effective in treatment-resistant schizophrenia. However, in certain clinical situations, such as the emergence of serious adverse effects, it is necessary to discontinue clozapine. Stopping clozapine treatment poses a particular challenge due to the risk of psychotic relapse, as well as the development of withdrawal symptoms. Despite these challenges for the clinician, there is currently no formal guidance on how to safely to discontinue clozapine. We assessed the feasibility of developing evidence-based recommendations for (1) minimizing the risk of withdrawal symptoms, (2) managing withdrawal phenomena, and (3) commencing alternatives treatment when clozapine is discontinued. We then evaluated the recommendations against the Appraisal of Guidelines for Research and Evaluation (AGREE) II criteria. We produced 19 recommendations. The majority of these recommendation were evidence-based, although the strength of some recommendations was limited by a reliance of studies of medium to low quality. We discuss next steps in the refinement and validation of an evidence-based guideline for stopping clozapine and identify key outstanding questions.

Effect of sequential sedation and analgesia in preventing delirium and withdrawal symptoms in children after ventilator weaning / 中国当代儿科杂志

OBJECTIVES@#To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning.@*METHODS@#A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning.@*RESULTS@#There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01).@*CONCLUSIONS@#Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

Prevention of alcohol withdrawal seizure recurrence and treatment of other alcohol withdrawal symptoms in the emergency department: a rapid review.

BACKGROUND: Patients who experience harms from alcohol and other substance use often seek care in the emergency department (ED). ED visits related to alcohol withdrawal have increased across the world during the COVID-19 pandemic. ED clinicians are responsible for risk-stratifying patients under time and resource constraints and must reliably identify those who are safe for outpatient management versus those who require more intensive levels of care. Published guidelines for alcohol withdrawal are largely limited to the primary care and outpatient settings, and do not provide specific guidance for ED use. The purpose of this review was to synthesize published evidence on the treatment of alcohol withdrawal syndrome in the ED. METHODS: We conducted a rapid review by searching MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials (1980 to 2020). We searched for grey literature on Google and hand-searched the conference abstracts of relevant addiction medicine and emergency medicine professional associations (2015 to 2020). We included interventional and observational studies that reported outcomes of clinical interventions aimed at treating alcohol withdrawal syndrome in adults in the ED. RESULTS: We identified 13 studies that met inclusion criteria for our review (7 randomized controlled trials and 6 observational studies). Most studies were at high/serious risk of bias. We divided studies based on intervention and summarized evidence narratively. Benzodiazepines decrease alcohol withdrawal seizure recurrence and treat other alcohol withdrawal symptoms, but no clear evidence supports the use of one benzodiazepine over another. It is unclear if symptom-triggered benzodiazepine protocols are effective for use in the ED. More evidence is needed to determine if phenobarbital, with or without benzodiazepines, can be used safely and effectively to treat alcohol withdrawal in the ED. Phenytoin does not have evidence of effectiveness at preventing withdrawal seizures in the ED. CONCLUSIONS: Few studies have evaluated the safety and efficacy of pharmacotherapies for alcohol withdrawal specifically in the ED setting. Benzodiazepines are the most evidence-based treatment for alcohol withdrawal in the ED. Pharmacotherapies that have demonstrated benefit for treatment of alcohol withdrawal in other inpatient and outpatient settings should be evaluated in the ED setting before routine use.

Characterizing Baclofen Withdrawal: A National Survey of Physician Experience.

OBJECTIVE: We studied physicians' opinions and experiences concerning clinical concerns, perceived severity, occurrence, and management of baclofen withdrawal due to abrupt discontinuation. METHODS: A nationwide 26-question electronic survey was distributed via e-mail to physicians (N = 952) representing varying specialties who manage spasticity with baclofen. A total of 110 physicians provided responses to the survey (response rate = 11.6%). Results were evaluated using descriptive statistics. RESULTS: Withdrawal from both oral and intrathecal (IT) baclofen was recognized as a significant concern and was observed by most respondents. However, approximately 75% and 35% of respondents or their clinic sites lack established management protocols for managing anticipated interruption of oral or IT baclofen, respectively. CONCLUSIONS: These findings highlight the need for further research on and the development of guidelines for the prevention and treatment of baclofen withdrawal. The results of this survey, along with a systematic literature review and multidisciplinary stakeholder input, may be helpful in establishing guidelines for the treatment and prevention of baclofen withdrawal.
