  1. Flu-related Hospitalizations by Industry Based on the article Influenza-associated Hospitalizations by Industry, 2009–10 Influenza Season, United States Dr. Sara Luckhaupt Medical Officer Centers for Disease Control and Prevention Emerging Infectious Diseases National Center for Emerging and Zoonotic Infectious Diseases Sara E.

  2. What was the purpose of the study? • Examine systematically collected flu surveillance data according to industry of employment • Although guidance for protecting workers from risk of infection from seasonal or pandemic flu already exists, more information is needed about which specific groups of workers are at highest risk of getting the flu or of having complications of infection. • This information could help improve the targeting of efforts to prevent flu to those occupational groups at greatest risk.

  3. What is the Emerging Infections Program? • Emerging Infections Program (EIP) • The EIP consists of a network of 10 state health departments and their collaborators in local health departments, academic institutions, other federal agencies, and public health and clinical laboratories. • The population of EIP network is roughly representative of the US population on the basis of demographic characteristics, such as age, gender, race, and urban residence, as well as population density and percent at or below the poverty level. • During 2009-2010 flu season, the 10 EIP sites performed active population-based surveillance for laboratory-confirmed flu-related hospitalizations.

  4. How was the study conducted? • Calculated ratios comparing the proportions of hospitalized workers that were employed in each industry sector to the proportions of the employed US population that are employed in each industry sector • e.g. compared the proportion of employed workers from the food services sector who were hospitalized to the proportion of employed workers from the food services sector within the entire US population

  5. What was found in this study? • People employed in the healthcare industry appear to be more likely to be hospitalized because of flu. • People in some other industries seem to have a greater chance of being hospitalized if they get the flu. • Planning for pandemic and seasonal flu is also important in these other industries.

  6. Who is most likely to be hospitalized because of the flu? • Workers were less likely to be hospitalized for the flu than non-workers. • We believe that this reflects underlying protective characteristics of workers versus non-workers. • Workers from some industry sectors were more commonly hospitalized than others. • It is impossible for us to conclude with certainty from this study which industry sector is at the highest risk. • The highest ratio of workers who were hospitalized was for the transportation and warehousing industry sector. • But the ratios for the health care industry, as well as a couple of other sectors, such as administrative, waste management, and related services; and accommodation and food services, were similar to the ratio for transportation and warehousing.

  7. What factors contributed to those people being hospitalized more than other people? • First, overrepresentation of an industry sector may be due to occupational risk factors for flu risks that these workers are more likely to face than others because of the nature of their job (e.g. exposure to sick members of the public). • Second, basic demographic and underlying health characteristics of the workers in some industry sectors may have led to an overrepresentation of those sectors. • These underlying health characteristics could put workers at an increased risk, both for acquiring the flu and for being hospitalized with it, and include things, such as older age chronic diseases, like diabetes or COPD, and poor access to healthcare.

  8. What factors contributed to those people being hospitalized more than other people? (cont.) • The workers within the sector of administrative, waste management, and related services may have low exposure to the public, but it may be that they may have underlying high-risk characteristics. Example: • Many people working in the sector of administrative, waste management, and related services have low salaries and may have problems with access to health care. • But in sectors such as health care and accommodation and food services workers may not have as many underlying high-risk characteristics, but they do have a high exposure to the public.

  9. Is not smoking recommended to help people stay well? • We didn’t actually have any information on the smoking status of the EIP cases in this study. • We presented population smoking data from the National Health Interview Survey as background because previous studies have suggested that smokers may be more likely to be hospitalized for flu. • It is possible that a higher incidence of smoking among workers in certain industries, for example accommodation and food services, may partially explain why we found evidence of an increased risk for hospitalization with flu among those groups.

  10. Besides not smoking, what can people do to protect themselves against the flu and its complications? • The National Institute for Occupational Safety and Health webpage on seasonal flu in the workplace describes strategies for decreasing flu transmission. • getting flu vaccinations • proper hand washing • respiratory hygiene practices • recognizing flu signs and symptoms • These strategies can be found in more detail at www.cdc.gov/niosh/topics/flu/.
