Management Of Alcohol Withdrawal Research Articles

Promising strategies for the prevention of alcohol-related brain damage through optimised management of acute alcohol withdrawal: A focussed literature review.

There is an increasing awareness of the link between chronic alcohol consumption and the development of cognitive, behavioural and functional deficits. Currently, preventative strategies are limited and require engagement in dedicated long-term rehabilitation and sobriety services, the availability of which is low. The acute alcohol withdrawal syndrome is an episode of neurochemical imbalance leading to autonomic dysregulation, increased seizure risk and cognitive disorientation. In addition to harm from symptoms of alcohol withdrawal (e.g. seizures), the underpinning neurochemical changes may also lead to cytotoxicity through various cellular mechanisms, which long-term, may translate to some of the cognitive impairments observed in Alcohol-Related Brain Damage (ARBD). Here we review some of the pharmacological and neurochemical mechanisms underpinning alcohol withdrawal. We discuss the cellular and pharmacological basis of various potential neuroprotective strategies that warrant further exploration in clinical populations with a view to preventing the development of ARBD. Such strategies, when integrated into the clinical management of acute alcohol withdrawal, may impact large populations of individuals, who currently face limited dedicated service delivery and healthcare resource.

A detox dilemma beyond benzodiazepines; clonidine's quandary in alcohol withdrawal management.

Benzodiazepines are the primary method of treatment of alcohol withdrawal, though the American Society of Addiction Medicine guidelines also include alternative agents for consideration. Observations in a Department of Veterans Affairs (VA) psychiatric emergency room noted consistent benzodiazepine use with an overall lack of use of alternative agents, even with low Clinical Institute Withdrawal Assessment for Alcohol (CIWA) scores and in the absence of other concerning symptoms. Due to concerns of potential more-than-necessary benzodiazepine use, we analyzed adjunctive clonidine use for elevated blood pressure/pulse in alcohol withdrawal among this Veteran population. This is a single-site VA retrospective chart review of the psychiatric emergency room from July 1, 2022, to June 30, 2023, focused on patients with alcohol withdrawal managed on a CIWA protocol. Excluding concurrent opioid withdrawal and clonidine as home medication, 167 patient charts were analyzed for this study. Among 167 patients, 99 (59.3%) had comorbid hypertension. A total of 614 medication doses were given for elevated CIWA (373, 60.8%) and elevated blood pressure/pulse (241, 39.2%). Of the 241 doses for elevated blood pressure/pulse, only 2.5% were clonidine. Among all benzodiazepine doses, 75.3% were given to patients with comorbid hypertension. Clonidine was administered to 3.0% of patients, making up 2.5% of total dosing. Alcohol withdrawal management lacks optimization. Integrating adjunctive medications could reduce potential benzodiazepine overuse effectively addressing elevated blood pressure/pulse. This study sheds light on the potential underutilization of clonidine and its potential role in improving alcohol withdrawal syndrome management. By addressing elevated blood pressure/pulse and curbing potential overuse of benzodiazepines, it may contribute to further optimizing patient care.

Oral ethanol prescribing for alcohol withdrawal syndrome: initial findings and future directions following implementation within a United Kingdom National Health Service setting

Introduction Prescribing of ethanol may be an alternative to benzodiazepines for managing alcohol withdrawal syndrome. We present our experience of oral ethanol prescribing within an acute United Kingdom National Health Service setting. Methods A retrospective review of patients presenting with alcohol withdrawal who were managed with oral ethanol or benzodiazepines was performed from data collected across two acute care settings. Ethanol prescribing inclusion: high risk of delirium tremens, or a history of harmful alcohol consumption (typically ≥30 units/day; in which 1 unit = 8 grams of alcohol; one standard United States drink = 14 grams of alcohol) or known to have a history of severe alcohol withdrawal, alcohol-related seizures or delirium tremens. Inverse propensity score weighting was used to partially account for variance between the two patient populations. Results Fifty (82 per cent male; average age 50.9 years) and 93 (84 per cent male; average age 46.5 years) patients in receipt of benzodiazepines or ethanol, respectively, were included. The likelihood of hospital admission was significantly reduced when individuals were managed with ethanol (odds ratio 0.206 (95 per cent confidence interval; 0.066-0.641), Wald chi-square P = 0.006). In those not admitted, the treatment type had no significant impact on length of stay or the number of occasions a pharmacological agent was required. In those admitted, treatment had no significant effect on length of stay. Discussion We offer preliminary evidence to support a role of oral ethanol in the management of patients with alcohol withdrawal. We have implemented a robust and translatable guideline. Despite limitations in the data set the impact of ethanol in reducing the likelihood of admission remained significant. Conclusions In individuals at significant risk of severe alcohol withdrawal, prescribing ethanol as part of a comprehensive care plan, may reduce unplanned admissions. The preliminary findings presented here warrant further assessment through prospective studies.

Effectiveness of Gabapentin as a Benzodiazepine-Sparing Agent in Alcohol Withdrawal Syndrome.

Background and Objectives: Gabapentin has shown promise as a potential agent for the treatment of alcohol withdrawal syndrome. We aimed to evaluate the effectiveness of gabapentin as a benzodiazepine-sparing agent in patients undergoing alcohol withdrawal treatment in all the hospitals of a large tertiary healthcare system. Materials and Methods: Medical records of patients admitted to the hospital for alcohol withdrawal management between 1 January 2020 and 31 August 2022 were reviewed. Patients were divided into two cohorts: benzodiazepine-only treatment who received benzodiazepines as the primary pharmacotherapy and gabapentin adjunctive treatment who received gabapentin in addition to benzodiazepines. The outcomes assessed included the total benzodiazepine dosage administered during the treatment and the length of hospital stay. The statistical models were calibrated to account for various factors. Results: A total of 4364 patients were included in the final analysis. Among these, 79 patients (1.8%) received gabapentin in addition to benzodiazepines, and 4285 patients (98.2%) received benzodiazepines only. Patients administered gabapentin required significantly lower average cumulative benzodiazepine dosages, approximately 17.9% less, compared to those not receiving gabapentin (median 2 mg vs. 4 mg of lorazepam equivalent dose (p < 0.01)). However, there were no significant differences in outcomes between the two groups. Conclusions: Our findings demonstrate that using gabapentin with benzodiazepine was associated with a reduction in the cumulative benzodiazepine dosage for alcohol withdrawal. Considering gabapentin as an adjunctive therapy holds promise for patients with comorbidities who could benefit from reducing benzodiazepine dose. This strategy warrants further investigation.

Alcohol Withdrawal Severity Measures for Identifying Patients Requiring High-Intensity Care.

Alcohol withdrawal syndrome (AWS) may progress to require high-intensity care. Approaches to identify hospitalized patients with AWS who received higher level of care have not been previously examined. This study aimed to examine the utility of Clinical Institute Withdrawal Assessment Alcohol Revised (CIWA-Ar) for alcohol scale scores and medication doses for alcohol withdrawal management in identifying patients who received high-intensity care. A multicenter observational cohort study of hospitalized adults with alcohol withdrawal. University of Chicago Medical Center and University of Wisconsin Hospital. Inpatient encounters between November 2008 and February 2022 with a CIWA-Ar score greater than 0 and benzodiazepine or barbiturate administered within the first 24 hours. The primary composite outcome was patients who progressed to high-intensity care (intermediate care or ICU). None. Among the 8742 patients included in the study, 37.5% (n = 3280) progressed to high-intensity care. The odds ratio for the composite outcome increased above 1.0 when the CIWA-Ar score was 24. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) at this threshold were 0.12 (95% CI, 0.11-0.13), 0.95 (95% CI, 0.94-0.95), 0.58 (95% CI, 0.54-0.61), and 0.64 (95% CI, 0.63-0.65), respectively. The OR increased above 1.0 at a 24-hour lorazepam milligram equivalent dose cutoff of 15 mg. The sensitivity, specificity, PPV, and NPV at this threshold were 0.16 (95% CI, 0.14-0.17), 0.96 (95% CI, 0.95-0.96), 0.68 (95% CI, 0.65-0.72), and 0.65 (95% CI, 0.64-0.66), respectively. Neither CIWA-Ar scores nor medication dose cutoff points were effective measures for identifying patients with alcohol withdrawal who received high-intensity care. Research studies for examining outcomes in patients who deteriorate with AWS will require better methods for cohort identification.

Contemporary Management and Outcomes of Veterans Hospitalized With Alcohol Withdrawal: A Multicenter Retrospective Cohort Study.

Few studies describe contemporary alcohol withdrawal management in hospitalized settings or review current practices considering the guidelines by the American Society of Addiction Medicine (ASAM). We conducted a retrospective cohort study of patients hospitalized with alcohol withdrawal on medical or surgical wards in 19 Veteran Health Administration (VHA) hospitals between October 1, 2018, and September 30, 2019. Demographic and comorbidity data were obtained from the Veteran Health Administration Corporate Data Warehouse. Inpatient management and hospital outcomes were obtained by chart review. Factors associated with treatment duration and complicated withdrawal were examined. Of the 594 patients included in this study, 51% were managed with symptom-triggered therapy alone, 26% with fixed dose plus symptom-triggered therapy, 10% with front loading regimens plus symptom-triggered therapy, and 3% with fixed dose alone. The most common medication given was lorazepam (87%) followed by chlordiazepoxide (33%), diazepam (14%), and phenobarbital (6%). Symptom-triggered therapy alone (relative risk [RR], 0.68; 95% confidence interval [CI], 0.57-0.80) and front loading with symptom-triggered therapy (RR, 0.75; 95% CI, 0.62-0.92) were associated with reduced treatment duration. Lorazepam (RR, 1.20; 95% CI, 1.02-1.41) and phenobarbital (RR, 1.28; 95% CI, 1.06-1.54) were associated with increased treatment duration. Lorazepam (adjusted odds ratio, 4.30; 95% CI, 1.05-17.63) and phenobarbital (adjusted odds ratio, 6.51; 95% CI, 2.08-20.40) were also associated with complicated withdrawal. Overall, our results support guidelines by the ASAM to manage patients with long-acting benzodiazepines using symptom-triggered therapy. Health care systems that are using shorter acting benzodiazepines and fixed-dose regimens should consider updating alcohol withdrawal management pathways to follow ASAM recommendations.

Fixed-Dose Phenobarbital Versus As-Needed Benzodiazepines for the Management of Alcohol Withdrawal in Acute Care General Internal Medicine.

The management of patients at risk of severe alcohol withdrawal is challenging because conventional treatment with as-needed benzodiazepines may be ineffective. We created a fixed-dose phenobarbital protocol and compared patient outcomes using this protocol with an as-needed benzodiazepine protocol. Patients admitted from the emergency department (ED) to General Medicine from January 1 to June 30, 2022 and treated for alcohol withdrawal with a novel phenobarbital protocol were compared with all of the patients admitted from the ED to General Medicine from January 1 to June 30, 2018, and treated with as-needed benzodiazepines. The primary outcome was a composite of intensive care unit (ICU) transfer or mortality. Secondary outcomes included mortality, ICU transfer, seizure, length of stay, excess sedation, delirium, against medical advice discharge, 30-day re-admission, 30-day ED reevaluation, and antipsychotic use. There were 54 patients in the phenobarbital group and 197 in the benzodiazepine group. The phenobarbital group was less medically complex but had more risk factors for severe withdrawal. There was no difference in the primary outcome, although there was a trend toward benefit in the phenobarbital group (3.7 vs 8.1%, P = 0.26), and there was a lower incidence of delirium in the phenobarbital cohort (0 vs 8.6%, P = 0.03). Secondary outcome trends favored phenobarbital, with lower mortality, ICU transfer, seizure, oversedation, against medical advice discharge, and 30-day re-admissions. A subgroup analysis accounting for differences in patient populations in the primary analysis found similar results. Phenobarbital is as safe and effective as benzodiazepine-based protocols for the treatment of high-risk alcohol withdrawal, with lower rates of delirium.

Concurrent opioid and alcohol withdrawal management.

Concurrent alcohol and opioid withdrawal syndrome is a common and challenging clinical scenario with little published evidence or guidance to inform pharmacotherapy strategies. Concurrent use of benzodiazepines and opioid agonists, which are considered first-line agents for management of each withdrawal syndrome independently, is controversial and often avoided in clinical practice. Strategies to provide effective, simultaneous medication treatment of alcohol and opioid withdrawal while optimizing patient safety are demonstrated through 3 patient cases.

Impact of clinical rotational posting on attitude toward psychiatry of undergraduate medical students in Malaysia.

Almost all over the world, psychiatry training of undergraduate medical students has been criticized to be deficient in imparting required knowledge and improving the perception of students towards psychiatry and psychiatric treatment. Considering the large mental health need gap in the community, it is essential to improve undergraduate students' attitude toward psychiatry. Hence, this study was planned to study the impact of psychiatry clinical posting on attitude toward psychiatry of undergraduate medical students. Undergraduate medical students undergoing psychiatry posting were assessed on the first and last day of clinical posting with the help of semi-structured proforma consisting of sociodemographic information, favored future career choice, the relevance of psychiatry to their future careers, the usefulness of particular knowledge and skills, the value of knowledge of psychiatric specialties and the utility of different settings for learning psychiatry. After their clinical posting, students had a more positive attitude towards the usefulness of psychiatry knowledge in future general practice and the usefulness of psychiatry knowledge from undergraduate training in the future. Knowledge of alcohol withdrawal management, detection and management of delirium, and Mental Health Acts were perceived more essential in the future. Also, specialties such as deaddiction and child and adolescent psychiatry were felt more useful in future practice. After posting, students perceived that psychiatry can also be learned at medical and surgical wards as well as during home visits. However, despite some positive changes in attitude toward psychiatry, there was no significant change in choosing psychiatry as a career by the students after posting. Undergraduate psychiatry training during clinical posting was able to make some positive changes in the knowledge and attitude of students. However, still, there were lacunae in some areas of concern. Preference of psychiatry as a branch of specialization was not increased after posting. This indicates the need for better reforms in psychiatry education at the undergraduate level to improve the perception of undergraduate students about psychiatry.

Alcohol relapse prevention health care after alcohol withdrawal in New South Wales prisons, Australia: A patient file review.

People who enter custody have complex health issues and comorbidities may include alcohol use disorders. We investigated clinical service provision and comorbidities recorded among individuals with a likely alcohol withdrawal syndrome within prison in New South Wales, Australia. For this clinical case series review, electronic medical data were used to identify 50 people entering custody between August and November 2018 who likely had a treated alcohol withdrawal syndrome. We aimed for a 3:2 ratio of men and women, and a 1:1 ratio of Aboriginal and non-Aboriginal individuals. Data were extracted using a purposefully designed tool which included current alcohol withdrawal management, comorbidities and alcohol relapse prevention approaches used or recommended. Thirty-eight men and 12 women, of whom 22 were Aboriginal, were included. Twenty-nine individuals (58%) reported a history of medical comorbidities. Thirty-five (70%) reported using other substances and over half (60%) had a diagnosis of mental health disorders. Fourteen (28%) individuals had a record of receiving brief intervention and five (10%) of motivational interviewing. Twenty-three individuals (46%) were referred to and seen by drug and alcohol clinicians. Only seven (14%) of the sample had pre-release community care plans. Individuals treated for an alcohol withdrawal syndrome in New South Wales prisons have a high prevalence of medical comorbidities and other substance use. Clinical interventions focused on alcohol withdrawal management, and relapse prevention interventions were not recorded for most individuals. Service innovation and expansion are needed to increase the provision of post-withdrawal management.

A Comparison of Injectable Diazepam and Lorazepam in the Goal-Directed Management of Severe Alcohol Withdrawal.

Benzodiazepines are the gold standard for treatment of alcohol withdrawal, yet the selection of a preferred benzodiazepine is limited due to a lack of comparative studies. The primary objective of this study was to compare the efficacy and safety of injectable lorazepam (LZP) and diazepam (DZP) in the treatment of severe alcohol withdrawal syndrome (AWS). Retrospective cohort study of adult patients admitted to an intensive care unit with a primary diagnosis of AWS. Subjects who received at least 12 LZP equivalent units (LEU) of injectable DZP or LZP within 24 hours of initiation of the severe AWS protocol were included. The primary outcome was time with Clinical Institute Withdrawal Assessment for Alcohol-Revised (CIWA-Ar) scores at goal over the first 24 hours of treatment. A total of 191 patients were included (DZP n = 89, LZP n = 102). Time with CIWA-Ar scores at goal during the first 24 hours was similar between groups (DZP 12 hours [interquartile range, IQR, = 9-15] vs LZP 14 hours [IQR = 10-17]), P = 0.06). At 24 hours, LEU requirement was similar (DZP 40 [IQR = 22-78] vs LZP 32 [IQR = 18-56], P = 0.05). Drug cost at 24 hours was higher in the DZP group ($204.6 [IQR = 112.53-398.97] vs $8 [IQR = 4.5-14], P < 0.01). DZP or LZP are equally efficacious for the treatment of severe AWS. LZP may be preferred due to cost but both medications can be used interchangeably based on availability.

Post-healing perceptions and experiences of alcohol withdrawal and life management in men with alcoholic pancreatitis: a qualitative study.

The aim of this study was to examine the perceptions and experiences of male patients with alcoholic pancreatitis after healing regarding alcohol withdrawal and life management. This study used a qualitative descriptive design, and participants were selected by purposive sampling from two tertiary care hospitals in Shandong Province, China. Semi-structured in-depth interviews were conducted with 18 male patients discharged from the gastroenterology department who had recovered from alcoholic pancreatitis. Colaizzi's method was used to analyze the interview data, and the findings were reported using COREQ criteria. By analyzing the interview data, we summarized five themes, (1) the dilemma of sobriety, (2) role change, (3) illness status, (4) family influence, and (5) life management. By profiling the perceptions and experiences of post-healing alcoholic pancreatitis patients' alcohol cessation and life management in men, it helps to grasp the details of alcohol cessation and health direction of patients' home management, which provides more directional guidance to help patients maintain positive and good lifestyle habits and active management awareness, followed by targeted personalized interventions to provide patients with knowledge of disease care and health management.

Digitally Assisted Peer Recovery Coach to Facilitate Linkage to Outpatient Treatment Following Inpatient Alcohol Withdrawal Treatment: Proof-of-Concept Pilot Study.

Alcohol use disorder (AUD), associated with significant morbidity and mortality, continues to be a major public health problem. The COVID-19 pandemic exacerbated the impact of AUD, with a 25% increase in alcohol-related mortality from 2019 to 2020. Thus, innovative treatments for AUD are urgently needed. While inpatient alcohol withdrawal management (detoxification) is often an entry point for recovery, most do not successfully link to ongoing treatment. Transitions between inpatient and outpatient treatment pose many challenges to successful treatment continuation. Peer recovery coaches-individuals with the lived experience of recovery who obtain training to be coaches-are increasingly used to assist individuals with AUD and may provide a degree of continuity during this transition. We aimed to evaluate the feasibility of using an existing care coordination app (Lifeguard) to assist peer recovery coaches in supporting patients after discharge and facilitating linkage to care. This study was conducted on an American Society of Addiction Medicine-Level IV inpatient withdrawal management unit within an academic medical center in Boston, MA. After providing informed consent, participants were contacted by the coach through the app, and after discharge, received daily prompts to complete a modified version of the brief addiction monitor (BAM). The BAM inquired about alcohol use, risky, and protective factors. The coach sent daily motivational texts and appointment reminders and checked in if BAM responses were concerning. Postdischarge follow-up continued for 30 days. The following feasibility outcomes were evaluated: (1) proportion of participants engaging with the coach before discharge, (2) proportion of participants and the number of days engaging with the coach after discharge, (3) proportion of participants and the number of days responding to BAM prompts, and (4) proportion of participants successfully linking with addiction treatment by 30-day follow-up. All 10 participants were men, averaged 50.5 years old, and were mostly White (n=6), non-Hispanic (n=9), and single (n=8). Overall, 8 participants successfully engaged with the coach prior to discharge. Following discharge, 6 participants continued to engage with the coach, doing so on an average of 5.3 days (SD 7.3, range 0-20 days); 5 participants responded to the BAM prompts during the follow-up, doing so on an average of 4.6 days (SD 6.9, range 0-21 days). Half (n=5) successfully linked with ongoing addiction treatment during the follow-up. The participants who engaged with the coach post discharge, compared to those who did not, were significantly more likely to link with treatment (83% vs 0%, χ2=6.67, P=.01). The results demonstrated that a digitally assisted peer recovery coach may be feasible in facilitating linkage to care following discharge from inpatient withdrawal management treatment. Further research is warranted to evaluate the potential role for peer recovery coaches in improving postdischarge outcomes.

Impact of an Educational Intervention on Hospital Pharmacists' Knowledge and Application of Substance Withdrawal Management.

Patients with substance use disorders are often encountered in an acute care setting and withdrawal management is important. Available literature reveals inadequate acute management of substance withdrawal due to lack of experience and knowledge of medications. A quality improvement project was implemented to improve hospital pharmacists' knowledge, application, and practice of inpatient opioid and alcohol withdrawal management through provision of didactic and case-based education and implementation of practice based prospective drug utilization review (PDUR). Pharmacists' knowledge of the management of alcohol and opioid withdrawal was assessed by a 10-item survey pre-and post-intervention. Twenty-one pharmacists completed the education and pre- and post-surveys. Scores for the 21 pharmacists improved significantly, with pre- and post-intervention scores of 7.33 ± 1.98 and 8.86 ± 0.91, respectively (P = .0035). Most pharmacists completed their required PDUR submission, and several pharmacist interventions were made and accepted post-education. Pharmacists indicated that the education increased their confidence and enabled them to learn new information that could be directly applied to their pharmacy practice. Providing education and requiring a PDUR improved pharmacists' knowledge, application, and practice of inpatient opioid and alcohol withdrawal management. Re-education or expanded education may be warranted to further increase pharmacists' competence.

818: THE IMPACT OF A BENZODIAZEPINE-SPARING STRATEGY ON ALCOHOL WITHDRAWAL MANAGEMENT

Introduction: The objective of this study was to assess the impact of a benzodiazepine-sparing strategy on overall benzodiazepine use in alcohol withdrawal management. Commonly utilized agents in benzodiazepine-sparing strategies include clonidine, gabapentin, and dexmedetomidine. These agents are less potent than benzodiazepines individually, but literature reveals using higher doses and combinations of these agents to target multiple pathways may provide similar efficacy with less adverse events. Methods: This is a chart review of trauma and surgical patients at a large, community hospital. Patients managed for alcohol withdrawal prior to implementation of a benzodiazepine-sparing protocol were compared to patients managed post-implementation of a protocol. Those included had a Prediction of Alcohol Withdrawal Severity Scale (PAWSS) score ≥ 4 or clinical suspicion of alcohol withdrawal. The primary outcome was decreased overall benzodiazepine use in lorazepam equivalents in milligrams. Secondary outcomes evaluated duration of alcohol withdrawal symptoms and adverse effects. Descriptive statistics were utilized to analyze primary and secondary outcomes as well as baseline characteristics. Propensity matching was performed using IBM SPSS Statistics version 25.0 (IBM Inc., Armonk, NY). Results: A total of 25 patients received a benzodiazepine-sparing strategy and 159 patients were in the control group. The intervention arm required a median of 2 mg [IQR: 0, 14] of benzodiazepines (lorazepam equivalents) compared to the control arm who required a median of 10 mg [IQR: 2, 28]. Propensity matching yielded similar results with the intervention arm receiving a median of 8 mg [IQR: 2, 25] of benzodiazepines (lorazepam equivalents) versus a median of 13 mg [IQR: 9, 37]) in the control arm. The intervention arm experienced alcohol withdrawal symptoms for a median of 1 day [IQR: 0,6]; whereas, the control arm experienced symptoms for a median of 5 days [IQR: 0, 4]. Conclusions: Utilization of a benzodiazepine-sparing strategy was associated with a reduction in overall benzodiazepine exposure. The results of this study implicate a need for further robust trials to establish the safety of benzodiazepine-sparing protocols and the ability to improve clinically meaningful outcomes.

787: STANDARDIZING PHENOBARBITAL USE IN ALCOHOL WITHDRAWAL SYNDROME FOR A MULTIHOSPITAL SYSTEM

Introduction: Phenobarbital (PHB) use in the treatment of alcohol withdrawal syndrome (AWS) has become common in clinical practice despite the lack of dosing standardization and when to initiate PHB. Recently, clinical trials have evaluated PHB as a safe and effective alternative to benzodiazepines (BZD). The ASAM Guidelines on Alcohol Withdrawal Management recommend the use of PHB only by clinicians experienced in its use and where extensive monitoring may occur. PHB is listed as an alternative to BZDs for severe AWS, but otherwise is only recommended in patients with a contraindication to BZDs. The objective of this project is to assess PHB use to determine a standardized dosing recommendation for patients experiencing AWS, leading to an improved understanding of PHB resulting in improved outcomes. Methods: This retrospective, multicenter, observational cohort included patients ≥18 years of age admitted to 16 AAH hospitals in WI and IL between June 4, 2021 to August 30, 2021 who received PHB for the treatment of AWS. Clinical data was extracted from the electronic medical record by chart review including comorbid conditions, PHB form and dose, CIWA scores before and 24 hours after PHB administration, and total concomitant BZD use. The primary outcome was improvement in median CIWA score after PHB administration while secondary outcomes included admission to the ICU, intubation, and death. Results: 100 patients were included. Improvement in median CIWA score after PHB occurred in both moderate and severe initial CIWA scores. Median severe initial CIWA scores decreased from 23 to 7 about 24 hours after PHB and median moderate initial CIWA scores decreased from 12 to 4 about 24 hours after PHB. Looking at where PHB orders were placed, 56 orders were in the ICU, 15 orders were in the ED, and the remaining placed on a general medicine floor. Prior to PHB, 18 patients were intubated with only 3 patients needing intubation after PHB. Only 4 patients who received PHB died with 2 related to a cancer diagnosis and the remaining 2 unrelated to AWS. Conclusions: The project concluded there was a decrease in CIWA scores after PHB in both moderate and severe AWS with the largest reduction in CIWA scores seen in patients with severe AWS. Earlier phenobarbital was associated with lower BZD use.

RNA biomarkers for alcohol use disorder.

Alcohol use disorder (AUD) is highly prevalent and one of the leading causes of disability in the US and around the world. There are some molecular biomarkers of heavy alcohol use and liver damage which can suggest AUD, but these are lacking in sensitivity and specificity. AUD treatment involves psychosocial interventions and medications for managing alcohol withdrawal, assisting in abstinence and reduced drinking (naltrexone, acamprosate, disulfiram, and some off-label medications), and treating comorbid psychiatric conditions (e.g., depression and anxiety). It has been suggested that various patient groups within the heterogeneous AUD population would respond more favorably to specific treatment approaches. For example, there is some evidence that so-called reward-drinkers respond better to naltrexone than acamprosate. However, there are currently no objective molecular markers to separate patients into optimal treatment groups or any markers of treatment response. Objective molecular biomarkers could aid in AUD diagnosis and patient stratification, which could personalize treatment and improve outcomes through more targeted interventions. Biomarkers of treatment response could also improve AUD management and treatment development. Systems biology considers complex diseases and emergent behaviors as the outcome of interactions and crosstalk between biomolecular networks. A systems approach that uses transcriptomic (or other -omic data, e.g., methylome, proteome, metabolome) can capture genetic and environmental factors associated with AUD and potentially provide sensitive, specific, and objective biomarkers to guide patient stratification, prognosis of treatment response or relapse, and predict optimal treatments. This Review describes and highlights state-of-the-art research on employing transcriptomic data and artificial intelligence (AI) methods to serve as molecular biomarkers with the goal of improving the clinical management of AUD. Considerations about future directions are also discussed.

Management of Post-Acute Alcohol Withdrawal: A Mixed-Studies Scoping Review

This article reviews research on post-acute alcohol withdrawal syndrome (PAWS) management. We conducted a PRISMA (Preferred Reporting Items for Systematic Revision and Meta-Analyses)-guided scoping review of the published PAWS literature, searching six electronic databases (from their inception through December 2020) for English-language randomized and nonrandomized studies. A total of 16 treatment studies met the inclusion criteria. The strength of evidence overall for pharmacologic treatments is low, with often only short-term results being reported, small treatment samples used, or inconsistent results found. However, for negative affect and sleep symptoms, more evidence supports using gabapentinoids (gabapentin and pregabalin) and anticonvulsants (carbamazepine and oxcarbazepine). Although preliminary data support acamprosate, there were no controlled trials. Despite an older treatment trial showing some positive data for amitriptyline for mood, the clinical measures used were problematic, and side effects and safety profile limit its utility. Finally, there is no evidence that melatonin and other agents (homatropine, Proproten-100) show PAWS symptoms. Although there is some evidence for targeted pharmacotherapy for treating specific PAWS symptoms, there are few recent, robust, placebo-controlled trials, and the level of evidence for treatment efficacy is low.
