Harmonized Biosurveillance Use Case By Resty Namata, Maria Metty & Priyaranjan Tokachichu December 13, 2007
Brief History From November 2002 to 31 July 2003 Severe Acute Respiratory Syndrome in Asia WHO estimates up-to 60 % of cases were healthcare workers Sverdlovsk, Russia Accidental release of anthrax from bio-weapons plant. 6 people with flu-like symptoms not treated for anthrax. 21 people had died before lab results confirmed anthrax Following September 11, 2001 Anthrax release in United States Detected early because nation was on heightened alert.
Biosurveillance Use Case Requirements Attributes: Real-time Fulfilled by data transmission from HER Timeliness Define by Michael Wagner et al. as difference between time of event detection & time event occurred Ultimate Goal: Early detection Need to early detection of natural or man-made disease outbreak in order to mobilize resources and minimize morbidity and mortality Transmit real-time data from healthcare providers to Public health Agency within 24hr lag

Effective Treatment Period Gain of 2 days Early Detection Traditional Disease Detection Phase II Acute Illness Phase I Initial Symptoms * Use Case Data is collected after lab results and diagnosis Case for early detection Category A disease agents cause non-specific symptoms like fever, cough & fatigue People don’t seek medical care during effective treatment period. For example: Consumer Healthcare Products Association survey: 42% of people with “flu” symptoms purchased over-the-counter(OTC) medication prior seeking medical care.
Proposal Collect sales data of over-the-counter healthcare product such as electrolytes, diarrhea, cough, thermometer and fever medications from retail stores and transmit it to public health agency * Available from National Retail Data Monitor System * It is low cost * It has been correlated with disease outbreak. * It is routinely collected for supply chain management

Recommendation We Recommend adding this data with reservations because: 1.It is difficult for public health to understand the data 2.OTC Data is noisy 3. Hard to identify a person who purchased a product. 4. Due to competitive agreements the store cannot be identified either.
