Alcohol withdrawal can be a serious, life-threatening condition, and hospitals play a crucial role in managing acute withdrawal symptoms and preventing high morbidity and mortality. Early detection and treatment are critical, and hospitals employ various tools and protocols to assess the severity of a patient's withdrawal symptoms. Benzodiazepines are a mainstay of treatment, stimulating the GABA receptor to reduce neuronal activity and slow the progression of symptoms. However, recent studies have also promoted a symptom-triggered approach that involves repeated patient assessments and results in less total drug use. In severe cases, hospitals may resort to heavy sedation, sometimes requiring intubation, but this introduces risks for additional complications. Nutritional supplementation and multivitamins may also be provided, depending on the patient's nourishment state.

What You'll Learn
Benzodiazepines are the mainstay of treatment
Benzodiazepines are the most common treatment for alcohol withdrawal. They work by stimulating the gamma-aminobutyric acid (GABA) receptor, which reduces neuronal activity, creating a sedative effect and slowing the progression of withdrawal symptoms. Long-acting benzodiazepines, such as chlordiazepoxide and diazepam, are the preferred choice for most patients. Their active metabolites have a rapid onset, and their long half-lives reduce the occurrence of breakthrough symptoms and rebound phenomena, such as seizures. Benzodiazepines with shorter half-lives, like lorazepam and oxazepam, are recommended for patients with liver dysfunction or those prone to respiratory depression. Intravenous administration is the standard route for patients with acute severe withdrawal, delirium tremens, and seizures.
The dosage of benzodiazepines is critical in treating alcohol withdrawal. Treatment centres have traditionally used fixed-dose schedules. However, recent studies advocate for a symptom-triggered approach, which involves repeated patient assessments and results in less total drug use without compromising efficacy. This approach is particularly important for patients with a history of alcohol abuse, as they may require higher doses to overcome autonomic hyperactivity.
Benzodiazepines are often used in conjunction with other treatments. For instance, ACT consultation is recommended for severe or complicated withdrawal when considering the addition of front-loading benzodiazepine and phenobarbital. Furthermore, gabapentin has been studied as a monotherapy and as an adjunctive treatment for inpatient alcohol withdrawal. It has been found to be at least as effective as standard benzodiazepine protocols for mild to moderate AWS, offering similar tolerability and reducing the time to discontinuation of the protocol.
While benzodiazepines are the mainstay of treatment, they are not the only option. For instance, multivitamins can be useful for clinically malnourished patients. Additionally, early detection and treatment are crucial for preventing high morbidity and mortality associated with severe alcohol withdrawal syndrome (SAWS). Finally, total and lifelong avoidance of alcohol is the best long-term treatment for those who have gone through alcohol withdrawal, as relapse can lead to increased morbidity and mortality.

ACT consultation for severe withdrawal
Alcohol withdrawal can cause a range of symptoms, from mild to severe, and in its most acute form, it may even become life-threatening. The symptoms arise when a person with alcohol use disorder stops or significantly reduces their alcohol intake. The severity of alcohol withdrawal symptoms is difficult to predict, and it depends on various factors, such as body chemistry, coexisting health conditions, medications, and the use of other substances. However, certain factors increase the risk of severe alcohol withdrawal, including heavy daily alcohol use, age above 65, and a history of delirium tremens or alcohol withdrawal seizures.
ACT consultation is recommended for patients experiencing severe alcohol withdrawal, particularly for symptoms like cravings, insomnia, or depression. It is also advised for patients requiring more than mild-to-moderate dosing of Ativan. ACT consultation is a part of a multidisciplinary decision involving the responsible physician, consult team, and nursing staff.
The Addiction Care Team (ACT) provides special expertise and step-by-step care for alcohol withdrawal. They assist patients who require fixed-dose therapy in combination with symptom-triggered therapy for optimal control of symptoms during hospitalization. ACT consultation is also recommended when considering the addition of front-loading benzodiazepine and phenobarbital.
Gabapentin is another treatment option that has been studied as monotherapy and as an adjunctive treatment for inpatient alcohol withdrawal. It has shown benefits in preventing relapse to drinking after acute withdrawal. Gabapentin is recommended for patients under 65 years of age with normal renal function, and the dosage can be adjusted as tolerated.

Assessing severity of withdrawal symptoms
Alcohol withdrawal syndrome is a clinical condition that may arise following the cessation or reduction of regular, heavy alcohol consumption. It poses a significant clinical challenge due to the spectrum of alcohol use disorders (AUD) and the variety of withdrawal symptoms. The severity of alcohol withdrawal symptoms can vary greatly from person to person, and it is challenging to predict with confidence who will experience life-threatening symptoms. Therefore, assessing the severity of withdrawal symptoms is crucial for determining the appropriate treatment plan and preventing disease progression.
The diagnosis of alcohol withdrawal syndrome is typically established through a comprehensive history and physical examination. Important historical data includes the quantity and duration of alcohol intake, time since the last drink, previous alcohol withdrawals, and the presence of concurrent medical or psychiatric conditions. A physical examination helps identify withdrawal symptoms and assess possible complicating medical conditions, such as arrhythmias, liver disease, and nervous system impairment. Basic laboratory investigations, such as a complete blood count, liver function tests, and blood alcohol and electrolyte level determinations, are also essential tools in the assessment process.
Healthcare providers may also utilise standardised scales, such as the Clinical Institute Withdrawal Assessment for Alcohol (CIWA-Ar), to quantify the severity of alcohol withdrawal symptoms. The CIWA-Ar is a validated tool that assesses common symptoms such as tremors, sensory disturbances, and agitation. Scores on the CIWA-Ar correspond to different levels of withdrawal severity: scores of 8 or less indicate mild withdrawal, scores between 8 and 15 indicate moderate withdrawal, and scores above 15 imply severe withdrawal with an increased risk of complications.
In addition to the CIWA-Ar, other assessment tools are available to evaluate the severity of alcohol withdrawal. These tools can be used to monitor the progression of withdrawal symptoms and guide pharmacotherapy dosing. However, it is essential to recognise that these tools provide guidance rather than strict criteria, and individualised treatment plans should consider the patient's unique circumstances and risk factors.
The decision to admit a patient to the hospital for alcohol withdrawal can be complex and depends on various factors. While most patients with mild to moderate withdrawal symptoms can be safely treated as outpatients, those with moderate to severe symptoms or specific risk factors typically require inpatient monitoring and treatment. Inpatient care ensures frequent reassessments to monitor the patient's condition and adjust treatment accordingly.

Managing symptoms and preventing harm
Medication and Treatment Approaches
Benzodiazepines are a mainstay of alcohol withdrawal treatment. They work by stimulating the gamma-aminobutyric acid (GABA) receptor, reducing neuronal activity and producing a sedative effect that slows the progression of withdrawal symptoms. Long-acting benzodiazepines such as chlordiazepoxide and diazepam are commonly used, while shorter-acting options like lorazepam and oxazepam are preferred for patients with liver dysfunction or respiratory depression. The initial dosage of benzodiazepines should be higher than typical anxiety treatment, and then adjusted based on the patient's response.
Additionally, the use of gabapentin as monotherapy or adjunctive treatment has shown promise in reducing hyperexcitability during alcohol withdrawal and preventing relapse after acute withdrawal.
For severe cases, heavy sedation may be required, and in some instances, patients may need to be intubated and breathe through a ventilator. However, intubation introduces risks for complications such as pneumonia and delirium.
Monitoring and Assessment
Close monitoring of patients is essential to manage alcohol withdrawal symptoms effectively. This includes monitoring vital signs such as heart rate, blood pressure, body temperature, and blood levels of certain chemicals. Additionally, patients are assessed for hallucinations and other signs of delirium tremens, a potentially life-threatening complication.
A tool like the Alcohol Withdrawal Clinical Assessment (AWCA) scale can help nurses determine medication dosing until effectiveness is achieved.
Nutritional Considerations
Malnourishment is a concern during alcohol withdrawal. Multivitamins can be beneficial for clinically malnourished patients. Additionally, ensuring proper daily nutritional supplementation is crucial during treatment.
Long-term Support
Providing long-term support for patients is an important aspect of preventing harm. This includes encouraging total and lifelong avoidance of alcohol (abstinence) and helping patients find living situations that support their sobriety. Psychiatric assessments and counselling are also recommended to address the underlying causes of alcohol dependence.

Treatment and recovery outlook
Treatment for alcohol withdrawal in a hospital setting is a serious and potentially life-threatening issue, requiring careful monitoring and management. The first step is often to assess the severity of the patient's withdrawal symptoms, which is traditionally done using the Clinical Institute Withdrawal Assessment for Alcohol (CIWA). An alternative method is the Alcohol Withdrawal Clinical Assessment (AWCA) scale, which can lead to more consistent scoring.
Pharmacological treatment is often required, with benzodiazepines being the mainstay of alcohol withdrawal treatment. These drugs work by stimulating the GABA receptor, reducing neuronal activity and thus slowing the progression of withdrawal symptoms. Long-acting benzodiazepines, such as chlordiazepoxide and diazepam, are the preferred choice, due to their rapid onset and long half-lives, which help prevent breakthrough symptoms such as seizures. For patients with liver dysfunction or respiratory depression, shorter-acting benzodiazepines like lorazepam and oxazepam are used. Intravenous administration is the standard route for patients with acute severe withdrawal, delirium tremens, and seizures.
In severe cases, heavy sedation may be required, and patients may need to be intubated and placed on a ventilator. This can introduce further risks, such as pneumonia, delirium, and vocal cord damage. As an alternative, a symptom-triggered approach has been promoted, which involves repeated assessments and adjustments of the patient's dosage. This method has been found to result in less total drug use while remaining as effective as fixed-dose schedules.
For patients with normal renal function under the age of 65, gabapentin has been studied as a potential treatment. It decreases glutamate-related hyperexcitability in alcohol withdrawal, and studies suggest it is at least as effective as benzodiazepine protocols for mild to moderate cases. Multivitamins can also be useful for patients who are clinically malnourished.
Following discharge, patients should not be provided with "as needed" (prn) medications to manage symptoms. Instead, they should be encouraged to seek ongoing support to avoid unhealthy alcohol use. This may include moving into supportive housing to aid in maintaining sobriety. Most people who go through alcohol withdrawal make a full recovery, but death is possible, especially if delirium tremens occurs. As such, early detection and treatment are crucial in preventing high morbidity and mortality.
