Key to table
System name (or subject area)
Name of surveillance system or subject area if the system doesn’t have a specific name
Event under surveillance

Disease – including injury, changes in health status, health outcomes
Hazards – risk and protective factors (including behaviours, population vulnerability, agent characteristics, and exposures) that
may affect health through specific, direct causal mechanisms

Determinants – causal factors that may affect health through multiple, often indirect pathways

Interventions – actions taken to control or prevent the occurrence of disease or minimise its negative health effects
Main purpose – Based on the stated or implied purpose of the current system


Control-focused – surveillance that aims to identify each occurrence of a particular disease, hazard or other health-related event
that requires a specific response and support delivery of an effective intervention

Strategy-focused – surveillance that provides information to support prevention strategies to reduce population health risk.
Prevention may precede disease (primary prevention) or be focused on reducing the effects of disease (secondary and tertiary
prevention)

Control-focused and strategy-focused – surveillance often meets both purposes as control-focused surveillance usually provides
information that can also be used for strategy-focused surveillance purposes
Coverage – Population or Setting


A description of the population or setting covered by the surveillance system and the completeness of that coverage
System type – Based on the type of current system

Event surveillance - prospective surveillance to identify in a timely manner each occurrence of a particular health-related event,
including disease and injury cases, outbreaks, health hazards and interventions

Screening - surveillance to identify a particular inapparent disease or pre-disposing risk factor in all members of a specified
population, or a particular health hazard in specified settings or environments

Service tracking - surveillance to identify delivery and non-delivery of a particular intervention or programme of agreed quality to
specified individuals, populations and settings

Prevalence surveys – surveillance based on repeated surveys to measure the prevalence over time of a particular disease or
injury, health state, health hazard, health determinant or intervention use in a specified population or setting

Monitoring - surveillance based on collection and periodic analysis and interpretation of information to characterise the
occurrence and distribution of a particular health-related event, including disease and injury cases, health states, health hazards,
determinants and interventions.
Reporting source

The point at which the health-related event or state is first detected and recorded by the surveillance system
Local/ Regional collation

The point at which information generated by the surveillance system is collected, analysed, and used at an institutional or
regional level, often to guide prevention and control measures
National collation

The point at which information generated by the surveillance system is collected, analysed, and used at a national level, often to
guide prevention policies and programmes
Reference(s)

Sources that provide a description of the surveillance system, including published and on-line information sources. In some
cases no appropriate documentation was identified as indicated by “NI” (for “not identified”) and information from key informants
and/or knowledge of the authors was used instead
