Changes in alcohol intoxication-related ambulance attendances during COVID-19: How have government announcements and policies affected ambulance call outs?

Abstract

Background: In response to COVID-19, government-mandated health directives including widespread lockdowns were implemented. Changes in alcohol purchasing were reported, with growing concern that alcohol may be consumed as a way to cope with pandemic-associated stressors. Hitherto, there have been limited studies examining alcohol-related harms, including acute harms requiring an ambulance, and their relationship to government announcements or policies related to COVID-19.Methods: Analyses were conducted between January and September 2020, with matched months in 2019, using Victorian data from the National Ambulance Surveillance System in Australia. Interrupted time series (ITS) models with odds ratios (OR) were used to map alcohol-related harms as a function of government policies for both metropolitan and regional areas.Findings: A total of 43,003 alcohol intoxication-related ambulance attendances occurred between January 2019 and September 2020. Attendances in the home increased in 2020 by 9% compared to matched 2019 months. The most socioeconomically advantaged cases showed the highest percentage change. ITS models showed decreased odds of alcohol-related attendances at the beginning of each COVID-19 wave in metropolitan (OR:0 • 77; 95%CI: 0 • 71-0 • 83; p < 0 • 001) and regional Victoria (OR: 0 • 72; 95%CI: 0 • 67-0 • 79, p < 0 • 001) separately, and increased odds following the introduction of harsher restrictions in metropolitan Melbourne (OR:1 • 07; 95%CI:1 • 01-1 • 11, p = 0 • 005). A 19% increase in odds of alcohol-related harms was observed at the end of the second wave lockdown period in regional Victoria (OR:1 • 19; 95%CI: 1 • 01-1 • 41, p = 0 • 004).Interpretation: Alcohol-related attendances during COVID-19 restrictions showed a displacement to home settings. Changes in patterns of harms were evident in specific sociodemographic groups, and geographic regions when mapped to government health directives. This study is one of the first to investigate alcohol-related harms at the population level in response to a global pandemic.

Impact of the COVID-19 Pandemic on the Profile of Patients in SAMU-Asturias EMS (Spain): A Two-Year Retrospective Analysis of Advanced Life Support Unit Data

“…16 In addition, there was an increase in the sales of alcoholic beverages in 2020 compared to 2019, mainly in susceptible populations (eg, middle age, low socioeconomic level, or mental disorders), as well as a change in the places of consumption, given the restrictions taken by the respective authorities. 17 It would also make sense to consider that the number of accidents, both at work and road traffic, as well as in sports or at school, would have been significantly reduced, since a very large part of the population was at home most of the time. Although one might think that domestic accidents would rise, it seems unlikely that they could equal those mentioned above.…”

Alcohol's harm to others in 2021: Who bears the burden?

“…In the year prior to the current survey, which was conducted in November-December 2021, COVID-19 and associated restrictions from February onwards affected the patterns of behaviour and association of many Australians, including their drinking patterns and locations [34]. Alcohol consumption decreased among lighter drinkers but increased among heavier drinkers in Australia [20,35], and similar patterns were observed in the United Kingdom [36]. In studies in Europe, COVID-19 was linked to an increase in some drinking-related harms, including mental ill-health, family violence and death [37][38][39].…”

“…financial constraints, transportation, treatment wait times and geographical proximity to treatment services) were less commonly identified ( May and Nielsen, 2019 ). Moreover, since 2020, access to treatment has been severely disrupted by the COVID-19 pandemic, a global public health emergency that has further increased alcohol consumption and related harms among vulnerable groups ( Pollard et al ., 2020 ; Sallie et al ., 2020 ; Ogeil et al ., 2021 ), and which has led to the rapid expansion of telehealth use worldwide in response to government policies aimed at containing virus transmission (e.g. social distancing, lockdowns).…”
