Data from monitoring and surveillance create the basis for the success and appropriate
delivery of the other nine policy options. Local, national and international monitoring
and surveillance are needed in order to monitor the magnitude and trends of alcohol-
related harms, to strengthen advocacy , to formulate policies and to assess impact
of interventions. Monitoring should also capture the prow le of people accessing
services and the reason why people most affected are not accessing prevention and
treatment services. Data may be available in other sectors, and good systems for
coordination, information exchange and collaboration are necessary in order to collect
the potentially broad range of information needed to have comprehensive monitoring
and surveillance.
