Assessing the impact of providing digital product information on the health risks of alcoholic beverages to the consumer at point of sale: A pilot study

Abstract

AbstractIntroductionThere is an ongoing policy debate in the European Union regarding the best method of providing information to consumers on the health risks of alcohol use. One of the proposed channels is via the provision of QR codes. This study tested the usage rate of QR codes placed on point‐of‐sale signs in a supermarket in Barcelona, Catalonia over a 1‐week period.MethodsNine banners with beverage‐specific health warnings in large text were prominently displayed in the alcohol section of a supermarket. Each banner provided a QR code of relatively large image size that linked to a government website providing further information on alcohol‐related harms. A comparison was made between the number of visits to the website and the number of customers in the supermarket (number of unique sales receipts) in a single week.ResultsOnly 6 out of 7079 customers scanned the QR code during the week, corresponding to a usage rate of 0.085%, less than 1 per 1000. The usage rate was 2.6 per 1000 among those who purchased alcohol.Discussion and ConclusionsDespite the availability of prominently displayed QR codes, the overwhelming majority of customers did not make use of the QR codes to obtain further information on alcohol‐related harms. This corroborates the results from other studies investigating customers' use of QR codes to obtain additional product information. Based on the current evidence, providing online access to information through QR codes will likely not reach a significant portion of consumers.
