Utility of Natural Language Processing for Clinical Quality Measures Reporting

Clinical quality measures (CQMs) are tools that help measure and track the quality of health care services. Measuring and reporting CQMs helps to ensure that our health care system is delivering effective, safe, efficient, patient-centered, equitable, and timely care. The CQM for influenza immunization measures the percentage of patients aged 6 months and older seen for a visit between October 1 and March 31 who received (or reports previous receipt of) an influenza immunization.

Influenza study of backyard animals in Georgia

Aquatic birds are the main reservoirs of influenza viruses, however, pigs represent an essential host in virus ecology as they are susceptible to both avian and human influenza viruses. Circulating zoonotic influenza (A/H7N9, A/H5N1, and A/H3N2v) viruses could mutate into forms easily transmissible from human-to-human and become a public health concern. Georgia is located along routes used by migrating birds where different species of aquatic birds are found. In 2006, highly pathogenic influenza virus A/H5N1 was detected in two wild swans in Adjara (western Georgia).

Utility of Nontraditional Data Sources for Early Detection of Influenza

 Influenza surveillance is conducted through a complex network of laboratory and epidemiologic systems essential for estimating population burden of disease, selecting influenza vaccine viruses, and detecting novel influenza viruses with pandemic potential (1). Influenza surveillance faces numerous challenges, such as constantly changing influenza viruses, substantial variability in the number of affected people and the severity of disease, nonspecific symptoms, and need for laboratory testing to confirm diagnosis.

Influenza-Associated Pediatric Deaths in the United States, 2010–2015

Community influenza infection rates are highest among children. In children, influenza can cause severe illness and complications including, respiratory failure and death. Annual influenza vaccination is recommended for all persons aged ≥ 6 months. In 2004, influenza- associated deaths in children became a notifiable condition. 

Objective

To characterize and describe influenza-associated pediatric deaths in the United States over five influenza seasons, 2010–11 through 2014–15.

Interpreting specific and general respiratory indicators in syndromic surveillance

Public Health England (PHE) uses syndromic surveillance systems to monitor for seasonal increases in respiratory illness. Respiratory illnesses create a considerable burden on health care services and therefore identifying the timing and intensity of peaks of activity is important for public health decision-making. Furthermore, identifying the incidence of specific respiratory pathogens circulating in the community is essential for targeting public health interventions e.g. vaccination.

Antibody Prevalence to Influenza Type A in Wild Boars of Northern Ukraine

Domestic swine have been viewed as important for the adaptation and spillover of IA from birds into human populations as they are sensitive to both avian and mammalian (including human) influenza viruses [1]. However, in much of Eurasia and North America wild swine are geographically widespread, abundant and often come in close contact with humans in rural and agricultural settings. Until recently, little attention has been paid to this as an alternate route for IA transmission to human and domestic populations and its significance is not clear.

Mortality surveillance in the Netherlands: winter 2015/2016 of moderate severity

The mortality monitoring system (initiated in 2009 during the influenza A(H1N1) pandemic) is a collaboration between the Centre for Infectious Disease Control (CIb) and Statistics Netherlands. The system monitors nation-wide reported number of deaths (population size 2014: 16.8 million) from all causes, as cause of death information is not available real-time. Data is received from Statistics Netherlands by weekly emails.

Predicting virologically confirmed influenza using school absences in PA

School-based influenza surveillance has been considered for real-time monitoring of influenza, as children 5-17 years old play an important role in community-level transmission.

Objective

To determine if all-cause and cause-specific school absences improve predictions of virologically confirmed influenza in the community.

Respiratory and circulatory deaths attributable to influenza A & B

Assigning causes of deaths to seasonal infectious diseases is difficult in part due to laboratory testing prior to death being uncommon. Since influenza (and other common respiratory pathogens) are therefore notoriously underreported as a (contributing) cause of death in deathcause statistics modeling studies are commonly used to estimate the impact of influenza on mortality.

Objective

To estimate mortality attributable to influenza adjusted for other common respiratory pathogens, baseline seasonal trends and extreme temperatures.

Comparative Analysis of Methods of Molecular Detection of Avian Influenza Virus

As part of this surveillance study for Avian Influenza both active and passive surveillance samples were tested using PCR and also utilized to validate the LAMP method. Active surveillance samples include pathological material and tracheal and cloacal swabs from ill poultry, which were subsequently assessed for avian influenza during diagnosis, and birds collected by hunters. Passive surveillance included environmental samples such as sand and bird faeces.
