Alcohol is the most commonly used substance in the United States, with over 75% of individuals aged 12 and older reporting lifetime consumption. Despite this, there are still gaps in our knowledge of alcohol withdrawal. While quantitative alcohol consumption accounts for about a third of the variability in the severity of acute withdrawal, there is a lack of systematic knowledge about other factors involved, making it difficult to precisely predict withdrawal severity in individual patients. This lack of understanding extends to the role of medical vs. social detoxification approaches, the influence of acute withdrawal treatment on long-term alcoholism outcomes, and the importance of chronic withdrawal. In addition, there is a dearth of research on the complex relationships among symptoms of AWS (alcohol withdrawal syndrome) and their interconnectedness with psychopathology, as well as limited data to guide withdrawal treatment in special clinical settings, such as those involving concurrent medical or psychiatric illnesses, or mixed substance dependence.

Gaps in research affect drinkers across the spectrum of alcohol involvement
Alcohol is the most commonly used substance in the United States, with over 75% of individuals aged 12 and older reporting lifetime consumption. Alcohol consumption spans a spectrum from low-risk to severe alcohol use disorder (AUD). Alcohol withdrawal syndrome (AWS) is common among hospitalised patients and can be fatal without appropriate pharmacologic management.
There are several gaps in the continuum of care that affect drinkers across the spectrum of alcohol involvement. Most studies and treatment approaches have focused on the more severe end of the spectrum—that is, people with severe, recurrent dependence. However, the vast majority of heavy drinkers do not have alcohol dependence or have a relatively milder, self-limiting form. There is a major gap in research concerning optimal treatment strategies for people with functional alcohol dependence. Currently, few services are available for this group because they fall between at-risk drinkers and those with severe recurrent alcohol dependence.
There is also a lack of systematic knowledge about the factors that influence the severity of acute withdrawal. This means that it is challenging to precisely predict the severity of withdrawal in individual patients. There is controversy over the role of medical vs. social detoxification approaches to acute withdrawal, the influence of acute withdrawal and its treatment on the long-term outcome of alcoholism, and the importance (or even existence) of chronic withdrawal.
Gaps in AWS research span the translational spectrum—from the use of animal models to approximate the complexities of human disease and support biomarker development, to predictive and prognostic enrichment strategies, rigorous clinical trials to evaluate therapies, and implementation studies.
Inpatient management of severe AWS is an area with significant research needs. Minimal evidence exists to guide inpatient management, and high-quality evidence to inform treatment decisions is lacking. A consultative, multidisciplinary approach is recommended for selecting medications and treatment protocols for alcohol withdrawal. However, this approach raises concerns about treatment delays and the misapplication of therapies, which may have adverse effects. Therefore, increased understanding and additional research are needed to address the unique needs of hospitalised patients with AWS and implement evidence-based practices effectively.

There is a lack of understanding of the unique needs of hospitalized patients with SAWS
Severe alcohol withdrawal syndrome (SAWS) is a highly morbid, costly, and common condition among hospitalized patients. However, there is a dearth of evidence and guidance to manage inpatient SAWS effectively. This gap in research spans the entire translational science spectrum, from basic science research to clinical practice and community health.
One critical aspect of this knowledge gap is the lack of understanding of the unique needs of hospitalized patients with SAWS. This gap in understanding has implications for treatment selection and patient care. For instance, previous guidelines and best practices for SAWS do not provide specific recommendations for hospitalized patients with co-occurring medical diseases. While a multidisciplinary approach is recommended for selecting medications and treatment protocols, it can also lead to treatment delays and the misapplication of therapies, which may have adverse effects.
The complexity of SAWS is further compounded by the involvement of providers from various disciplines, which may contribute to a lack of ownership and consistency in treatment approaches. Additionally, the diverse descriptions and definitions of SAWS in the literature present challenges in developing a standardized approach to treatment. This lack of standardization makes it difficult to compare the effectiveness of different treatments and determine the optimal approach for individual patients.
Furthermore, there is limited systematic knowledge about the factors influencing the severity of alcohol withdrawal. While quantitative alcohol consumption is known to impact severity, other factors remain unknown, hindering the ability to predict and manage individual patient outcomes effectively. This uncertainty extends to the role of medical versus social detoxification approaches, the long-term outcomes of acute withdrawal on alcoholism, and the existence or significance of chronic withdrawal.
Addressing these gaps in understanding the unique needs of hospitalized patients with SAWS requires additional research and a multidisciplinary approach. This includes rigorous clinical trials, predictive and prognostic enrichment strategies, and the development of evidence-based practices that can be successfully implemented to improve patient care and outcomes.

There is a lack of systematic knowledge about factors influencing the severity of acute withdrawal
Alcohol withdrawal syndrome (AWS) is a common condition among hospitalized patients, and severe cases can lead to life-threatening complications requiring urgent medical intervention. While the quantity of alcohol consumed accounts for about a third of the variability in the severity of acute withdrawal, there are indeed knowledge gaps regarding other influencing factors. This lack of systematic knowledge about the factors affecting acute withdrawal severity limits our ability to precisely predict the severity of withdrawal in individual patients.
The existing literature on alcohol withdrawal offers varying definitions and descriptions of severe alcohol withdrawal syndrome (SAWS), contributing to inconsistencies in research and clinical practice. The diverse nature of SAWS, which can manifest alongside organ failure, sepsis, or other critical illnesses, further complicates our understanding of the syndrome. The involvement of providers from various disciplines in caring for patients with SAWS underscores the need for standardized knowledge and practices.
The current treatment approaches for SAWS include a consultative, multidisciplinary method for selecting medications and treatment protocols. However, this approach has raised concerns about potential treatment delays and the incorrect application of therapies, which may have adverse effects. The lack of high-quality evidence to guide treatment decisions for inpatient AWS exacerbates this issue, as studies often exclude patients with serious medical comorbidities, even though such conditions frequently coexist with AWS in acute care settings.
To address these gaps in knowledge and practice, the American Thoracic Society (ATS) has taken on the responsibility of elevating research and care standards for patients experiencing SAWS. The ATS community, with its clinical and research expertise in managing severe cases of SAWS, serves as an ideal forum for content experts to identify and address the complexities of alcohol withdrawal. Their efforts aim to advance the care of hospitalized patients experiencing SAWS by offering recommendations for research across the translational science spectrum, from basic science research to community health.
Furthermore, the National Institute on Alcoholism and Alcohol Abuse (NIAAA) has been consulted to provide input and guidance in addressing these research gaps. The NIAAA recognizes alcohol as the most commonly used substance in the United States, underscoring the significance of comprehensive research and effective treatment strategies for alcohol withdrawal syndrome. Filling these knowledge gaps is crucial for developing evidence-based practices and improving patient care, clinical practice, and community health outcomes related to alcohol withdrawal.

There is a lack of high-quality evidence to guide treatment decisions for inpatient AWS
Alcohol withdrawal syndrome (AWS) is a common occurrence among hospitalised patients and can be fatal without appropriate pharmacologic management. Despite this, there is a dearth of high-quality evidence to guide treatment decisions for inpatient AWS. This gap in research is attributed to several factors. Firstly, studies examining treatments for inpatient AWS tend to have small sample sizes, limiting the generalisability of their findings. Moreover, these studies often exclude patients with serious medical and/or surgical comorbidities, even though such conditions frequently coexist with AWS, especially in critical care settings. This exclusion further reduces the applicability of the research findings to real-world clinical practice.
The diversity of healthcare providers involved in the care of patients with AWS may also contribute to the lack of standardised treatment protocols. Inpatient management of AWS typically involves a multidisciplinary team, including physicians, nurses, pharmacists, social workers, and other allied healthcare professionals. While this collaborative approach is essential for comprehensive patient care, it may also lead to a diffusion of responsibility and a lack of standardised treatment guidelines.
Another factor contributing to the gap in research is the varying definitions and descriptions of severe alcohol withdrawal syndrome (SAWS) in the literature. The diverse characterisations of SAWS make it challenging to develop standardised treatment protocols applicable across different clinical settings. To address this issue, a committee of experts was formed to develop a conceptual definition of SAWS using a modified Delphi approach. This initiative aimed to provide a unified framework for future research and clinical practice.
Furthermore, there are knowledge gaps regarding the factors influencing the severity of alcohol withdrawal. While the quantity of alcohol consumed is a significant factor, it only accounts for about one-third of the variability in the severity of acute withdrawal. There is a lack of systematic knowledge about the other contributing factors, making it challenging to predict and manage individual patient cases accurately. This uncertainty underscores the need for more comprehensive research to guide clinical decision-making in alcohol withdrawal treatment.
The current treatment landscape for alcohol withdrawal is predominantly managed by non-medical professionals, which creates a gap in the continuum of care. This gap in expertise may contribute to the lack of high-quality evidence-based research to guide treatment decisions for inpatient AWS. There is a need for increased involvement of medical professionals in the treatment of alcohol withdrawal to bridge this gap and improve patient outcomes.
