Sentinel events can be caused by major mistakes and negligence on the part of a healthcare provider, and are closely investigated by healthcare regulatory authorities. Sentinel events are identified under The Joint Commission (TJC) accreditation policies to help aid in root cause analysis and to assist in development of preventive measures.
A sentinel surveillance system is used to obtain data about a particular disease that cannot be obtained through a passive system such as summarizing standard public health reports. Data collected in a well-designed sentinel system can be used to signal trends, identify outbreaks and monitor disease burden, providing a rapid, economical ...
The classic example is the "canary in the coal mine".The idea of placing a warm-blooded animal in a mine to detect carbon monoxide was first proposed by John Scott Haldane in 1895, [2] and canaries were used as early as 1896.
On April 18, 2013, the Joint Commission issued a sentinel event alert that highlighted the widespread problem of alarm fatigue in hospitals. Their recommendations included establishing guidelines to tailor alarm settings, training all members of the clinical team on safe use of alarms, and sharing information about alarm-related incidents.

Examples of social media public health surveillance include HealthTweets, which gathers data from Twitter. [20] Twitter data is considered highly useful for public health research, as its data policies allow public access to 1% samples of raw tweets. Tweets can also be geolocated, which can be used to model the spread of contagious disease.

Event sampling methodology (ESM) refers to a diary study.ESM is also known as ecological momentary assessment (EMA) or experience sampling methodology.ESM includes sampling methods that allow researchers to study ongoing experiences and events by taking assessments one or more times per day per participant (n=1) in the naturally occurring social environment.
The Sentinel A4 is a complete redesign of the sensor that uses digital processing and solid-state antenna modules based on gallium nitride (GAN) transmitters. The scalable modular architecture is shared with the long-range AN/TPY-4 radar, which has 1000 individually controlled elements and uses GPU computing for signal processing.
