Adjuvanted Influenza Vaccination Year 2 Follow-On Survey
Adjuvanted Influenza Vaccination and Morbidity and Mortality in U.S. Nursing Homes: Assessment of Vaccine Selection and Outcomes for the Follow-on Study Year

Intervention / Treatment
Detailed Description
This study will enroll facilities who participated in the adjuvanted influenza vaccine study in 2016-2017 to document the vaccine choice for the 2017-2018 influenza season through a survey. Additional facilities will be enrolled that did not participate to answer a survey responding to questions regarding the vaccine choice for the 2017-2018 and 2018-2019 flu season. Both groups will also gather information on vaccination rates for residents and staff, policies and procedures, and influenza outbreaks.
The facility will complete a profile and answer questions regarding influenza vaccination in their facilities for the 2017-2018 and 2018-2019 flu seasons.
The study team will obtain data from the Centers for Medicare & Medicaid Services in 2019 to determine the study outcomes. None of the data used in the analysis will be linked to individual residents in facilities.

Follow-On Cohort
We will survey 823 nursing facilities who participated in the aTIV Influenza Vaccination and Morbitiy and Mortality in U.S. Nursing Homes study in 2016-2017.
We anticipate a 70% response rate from this sample for participation.
|
Facilities will be asked to complete a survey to evaluate the impact of the influenza vaccine choice on hospitalization risk for the 2017-2018 influenza season.
|
Parallel Cohort
We will survey an additional 1000 facilities (i.e., facilities not participating in the original 2016-2017 study, but meeting the same entry criteria, except prior use of high dose vaccine will be allowed) in order to capture a cohort that used a wide range of self-selected vaccine choices.
We anticipate a 50% response rate from this sample.

Facilities will be asked to complete a survey to evaluate the impact of the influenza vaccine choice on hospitalization risk for the 2017-2018 influenza season.
