Monitoring alcohol consumption is important for understanding drinking practices and patterns, and for detecting heavy drinking at an early stage. It can also help to identify alcohol-related health problems and prevent alcohol use disorder (AUD). There are several methods for monitoring alcohol consumption, including self-reporting, laboratory tests, biomarker assays, and the use of mobile applications. In settings such as restaurants and bars, monitoring alcohol consumption involves counting and recording drinks, using drink tickets, and observing guest behaviour for signs of intoxication.

What You'll Learn
Monitoring alcohol consumption in hospitality settings
Counting and Recording Drinks
One common approach is to count and record the number of drinks consumed by each guest. This can be done by noting the drinks on the back of the guest's check or using a drink ticket system, where each guest receives a set number of tickets representing one drink each. This provides a consistent and reliable measure of alcohol intake, especially when guests move between different areas of the venue, such as from the bar to the dining area.
Monitoring Guest Behaviour
In addition to counting drinks, it is crucial to observe guests' behaviour as they consume alcohol. Signs of intoxication may include slurred speech, imbalance, or loud and aggressive behaviour. By paying attention to behavioural changes, staff can gain a more comprehensive understanding of guests' intoxication levels and intervene appropriately.
Staff Communication and Training
Effective monitoring requires good communication among staff members. Staff should be trained to recognise signs of intoxication and understand how to manage it. They should also be aware of policies and procedures for handling situations where guests have consumed excessive alcohol. This includes knowing when to limit further alcohol service and ensuring guests have a safe way to get home.
Drinkaware Apps
Technology can also assist in monitoring alcohol consumption. Apps such as MyDrinkaware allow individuals to track their drinking habits, calculate units and calories, and set goals to moderate their drinking. These apps can provide personalised results, visual aids, and alerts to help individuals reduce their alcohol intake and improve their overall well-being.
Regular Updates and Periodic Counting
When guests are moving around a venue, it is important to periodically update their drink totals at various points. Regular counting helps maintain accuracy and enables staff to track how much each guest is drinking, even if they are not consistently in one area. This proactive approach prioritises guest safety by facilitating early intervention when necessary.
By implementing these strategies, hospitality venues can effectively monitor alcohol consumption, promote responsible drinking, and ensure the safety and well-being of their guests.

Using biomarkers to monitor consumption
Using biomarkers to monitor alcohol consumption can be an effective way to gain an objective and quantitative understanding of an individual's drinking patterns. Biomarkers are biochemical measurements that can assess a patient's current or past alcohol use. While there is no single perfect biomarker, a combination of these markers can provide valuable insights. Here are some commonly used biomarkers and their significance:
Gamma-Glutamyl Transferase (GGT)
GGT is an inexpensive and sensitive marker of alcohol consumption. It is elevated in drinkers compared to abstainers, even at moderate levels (60g/week). However, GGT lacks specificity as it can also be elevated due to non-alcoholic fatty liver disease, drug intoxication, obesity, diabetes, and hepatobiliary disorders. GGT levels are also age-dependent, increasing with age even in abstinent individuals.
Mean Corpuscular Volume (MCV)
MCV measures the average size of red blood cells, which increases with high alcohol ingestion. Compared to other biomarkers, MCV has low sensitivity but higher specificity for alcohol use. It is a useful indicator when combined with other markers.
Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT)
AST and ALT enzymes are sensitive and specific for detecting alcohol-induced liver damage. The AST/ALT ratio increases with alcohol consumption, and a ratio >1 suggests alcohol as the cause of liver dysfunction. ALT is less sensitive than AST, but both are effective in combination with other biomarkers to identify heavy drinking.
5-Hydroxytryptophol (5-HTOL)
5-HTOL is a biomarker that can be detected in urine for up to 24 hours after alcohol consumption, making it useful in forensic toxicology and for detecting recent heavy drinking. It is more sensitive and specific than standard alcohol measurements, which detect alcohol in the urine for about an hour per drink.
WBAA Assay
The WBAA assay measures hemoglobin-bound acetaldehyde, which accumulates in red blood cells over their average 120-day lifespan with continued drinking. This assay is highly specific, sensitive, and precise, and it is unique in its ability to provide a picture of alcohol consumption patterns over time. It is useful for monitoring patients in alcoholism treatment programs.
Experimental Markers
Several experimental markers show promise for measuring acute alcohol consumption and relapse. These include alcohol byproducts such as acetaldehyde, ethyl glucuronide (EtG), and fatty acid ethyl esters (FAEE), as well as alterations in sialic acid, a type of carbohydrate. Additionally, there is ongoing research into genetic markers that may predict an individual's predisposition to alcoholism, including differences in neurotransmitters like beta-endorphin and gamma-aminobutyric acid (GABA).
In conclusion, using biomarkers provides an objective and quantitative approach to monitoring alcohol consumption. By employing a combination of these biomarkers, clinicians can gain insights into both recent and long-term drinking patterns, aiding in the evaluation and treatment of patients with alcohol use disorders.

Screening for heavy drinking
Screening Tools and Questionnaires
The National Institute on Alcohol Abuse and Alcoholism (NIAAA) recommends using brief screening tools to identify unhealthy alcohol use. One such tool is the Alcohol Use Disorders Identification Test–Consumption (AUDIT-C), which consists of three questions related to drinking frequency and quantity. The responses are scored, and a higher score indicates a greater likelihood of alcohol affecting an individual's health and safety. The AUDIT-C is a subset of the full 10-question AUDIT, which can also be used for more comprehensive assessments. Other screening tools include the CAGE tool, which stands for Cut down, Annoyed, Guilty, and Eye-opener, and the T-ACE tool, which adds "Tolerance" to the CAGE questions. These tools are designed to be quick and easy to administer, requiring only 1-2 minutes, and can be used by any healthcare professional as part of a comprehensive health assessment.
Unhealthy Alcohol Use and AUD
Unhealthy alcohol use, also known as alcohol misuse, refers to drinking patterns that can cause health problems and lead to Alcohol Use Disorder (AUD). AUD is a brain disorder characterized by the inability to stop or control drinking, even when it causes distress and harm in various aspects of life. It can range from mild to severe and was previously called alcoholism or alcohol dependence. Binge drinking, which is drinking enough to reach a blood alcohol concentration (BAC) of 0.08% or more, is a form of unhealthy alcohol use that increases the risk of developing AUD. However, not everyone who binge drinks has AUD, and screening tests can help identify those at risk.
Screening as Part of Routine Care
The NIAAA and healthcare professionals recommend making alcohol screening a routine part of patient care. Screening can be done during routine health care visits or when a provider suspects a patient may have a problem with alcohol. The NIAAA Single Alcohol Screening Question (SASQ) is a simple screening method where the provider asks how often the patient has had an alcoholic drink in the past year, followed by additional questions if the patient answers positively. Screening for unhealthy alcohol use, combined with brief interventions when needed, is a cost-effective preventive service that can have significant health impacts.
Benefits of Early Detection
Early detection of heavy drinking and AUD can prevent greater harm and health complications. It is a myth that individuals with AUD need to hit "rock bottom" before changing their drinking habits. Additionally, asking about alcohol use can benefit the entire family, as family members of those with AUD tend to have more health problems and costly medical care. Screening can help identify individuals with alcohol problems and provide early intervention, potentially improving the health of their loved ones as well.
Monitoring Alcohol Consumption Patterns
Epidemiologists and researchers also monitor alcohol consumption patterns at the individual and population levels to understand the effects of interventions and policy measures. Repeated monitoring can be done through diary, longitudinal, or retrospective surveys for individuals, while population-level data can be collected through periodic surveys. This information helps track long-term trends, detect changes in drinking patterns, and inform prevention programs and policy changes related to alcohol consumption.

Monitoring consumption at a population level
Monitoring alcohol consumption at a population level is essential for understanding drinking practices and patterns in a community. This data can inform public health policies and interventions aimed at reducing alcohol-related harms. Here are some ways to approach monitoring alcohol consumption at a population level:
Surveys
Population surveys are a common method for collecting data on alcohol consumption. These surveys can be conducted at regular intervals to capture changes in drinking patterns over time. Surveys allow for the collection of individual-level data, such as drinking frequency, quantity, and context, which can then be aggregated to understand group-level consumption. While surveys are a practical approach, they may suffer from response biases and may not capture the full range of drinking behaviours in a population.
Sales and Taxation Data
Alcohol sales data can provide valuable insights into consumption patterns at a population level. By analysing sales figures, researchers can estimate the average consumption per capita and identify trends over time. Taxation data is also useful, as it provides information on the volume of alcohol sold and can be indicative of consumption patterns.
Epidemiological Studies
Epidemiological studies examine the patterns, causes, and effects of alcohol consumption in populations. These studies often involve analysing data from various sources, including surveys, sales figures, and health records. Epidemiologists can monitor current alcohol consumption, analyse long-term trends, and assess the consequences of drinking, such as traffic crashes and alcohol-related health issues.
Modelling and Distribution Analysis
Mathematical modelling can be used to analyse alcohol consumption distribution within a population. For example, the Log-Normal, Gamma, and Weibull prevalence distributions have been used to estimate alcohol consumption patterns and their impact on health issues such as diabetes, breast cancer, and pancreatitis. These models help characterise the relationship between alcohol consumption and disease burden.
Repeated Measurements
Repeated measurements over time are essential for understanding the effectiveness of policy changes related to alcohol consumption. Monitoring the impact of interventions such as alcohol taxes, availability controls, and health education campaigns can help evaluate their influence on drinking patterns at the population level.
By utilising these methods and more, public health professionals can gain valuable insights into population-level alcohol consumption. This knowledge informs policies and interventions, ultimately helping to reduce the harmful effects of alcohol on individuals and society.

Frequently asked questions
Monitoring your alcohol consumption can be done in several ways. You can use a free app such as MyDrinkaware, which allows you to track your alcohol consumption, calculate units and calories, and set goals to help you moderate your drinking. Alternatively, you can manually keep track of your drinking by logging drinks by type, size, and quantity.
One of the best ways to monitor a guest's alcohol consumption is by counting and recording the number of drinks on the back of the guest's check. This method, combined with vigilance regarding behavioural changes, offers a comprehensive approach to ensure guest safety. Another method is to use a drink ticket system, where each guest is given a set number of tickets, each representing one drink.
Signs of intoxication include slurred speech, imbalance, or overly loud or aggressive behaviour. It is important to stay vigilant for these signs as simply counting drinks might not always indicate potential over-intoxication.
Screening for heavy drinking can be done through self-reporting, laboratory tests, or biomarker tests. Laboratory tests include serum ethanol testing, which provides the most accurate determination of a patient's alcohol level, and testing for biomarkers such as CDT, PEth, GGT, MCV, AST, and ALT, which can indicate long-term heavy alcohol use or alcohol-induced liver damage.
