The expansion of commercial gambling within recent decades has been met by different regulatory and legislative responses from different countries. Such changes have included the gentle relaxation of regulations in certain jurisdictions and the setting up of government monopolies or regulation and taxation of operators in others 
. As part of the governments’ responses, attempts to address gambling-related problems through post hoc harm-minimization efforts, known as “responsible gambling” programs, have predominated for many years 
. Such initiatives place an emphasis on supporting the individual with their gambling-related problems through individualized treatment interventions (self-exclusion, therapy, etc.) 
. More recently, debate has centralized on the need to introduce a broader public health approach, with a focus on reducing the risks of gambling-related harm to individuals, affected others, and the population at large 
. Aspects of such an approach include increasing an awareness of gambling in order to build public knowledge and resilience, and increasing operator accountability over gambling offers 
. Alongside this debate, countries, such as Switzerland, have taken the first, tentative steps to adapt and modernize their approach towards gambling; an activity which is widespread across the country, as in most of Europe 
. Around 46.6% of the Swiss population are believed to gamble each year (73.6% within their lifetime) 
. This equates to an estimated 5 million people, of whom an estimated 76,000 are reported to gamble excessively 
. The estimated social costs, including healthcare costs, lost productivity, and reduction in quality of life are between 552 and 654 million Swiss Francs (623 to 739 million US Dollars) per year 
. It is likely that greater numbers are affected by less-severe gambling-related harms, including not only the players themselves but also those close to them, and their communities 
. In order to promote public health, policies incorporating prevention and harm-reduction features will be necessary to protect the population at large as well as those at risk (so called “prevention paradox”).
In a move towards modernizing and harmonizing pre-existing law and opening the market for online casino gambling, the Swiss electorate voted in the Swiss Federal Act on Gambling (Loi fédérale sur les jeux d’argent; LJAr) in June 2018. The new act, which entered into force in January 2019 
, recognizes the State’s obligation to adapt structural prevention measures, e.g., operator prevention programs, public education initiatives, etc., in relation to the risk levels of different gambling offers. In order to monitor gambling-related policy, two indicators are currently recognized within the Federal Office of Public Health National Addiction Strategy. These include (1) the number of casino exclusions (data annually produced by the Commission fédérale des maisons de jeu; CFMJ) and (2) excessive gambling prevalence (provided every 5 years by the Swiss Health Survey and mandated by the CFMJ) 
. Given the many facets of the new law, the need for a more extensive and comprehensive monitoring system is paramount.
