NCT01455753 | Completed

• 3 other identifiers: 0006P30AG034532P01AG005842
• Study Type: observational
• Target: 1,801
• Locations: 1 country

Brief Summary

Using desk location information and employees' building entry/exit swipe card data from a company that offered a free 2-day worksite influenza vaccination clinic, we separately identify the vaccination effects of base proximity-the inverse of walking distance between one's desk and the clinic-and functional proximity-the likelihood of passing near the clinic during the course of a normal work day (ie, days when the clinic is not open).

Conditions

Influenza; Human

Keywords

Influenza; Proximity

Outcome Measures

Primary Outcomes (1)

• Receipt of influenza vaccine

  The investigators will measure whether proximity to a flu shot clinic effected whether an employee received an influenza vaccine.

  One week

Secondary Outcomes (2)

• Absenteeism

  The investigators will follow employees' absenteeism for five to six months

• Demographic characteristics on flu shot participation

  Up to 3 years

Study Arms (1)

Employees

A total of 1,801 employees of a health benefits administrator that held a free workplace influenza vaccination clinic.

Other: Functional Proximity; Other: Base Proximity

Interventions

Functional Proximity OTHER

Using each employee's building entry/exit swipe card data, we test whether functional proximity-the likelihood that the employee walks by the clinic for reasons other than vaccination-predicts whether the employee gets vaccinated at the clinic.

Employees

Base Proximity OTHER

We also test whether base proximity-the inverse of walking distance from the employee's desk to the clinic-predicts vaccination probability.

Study Population

Employees at the headquarters of a health benefits administrator in the US. These employees are generally not health care personnel. All of them have health insurance. Of HQ employees, 520 are housed in Building 1 (the site of the vaccination clinic) and 1,281 are housed in Building 2. The two buildings are 131 meters apart and connected by an enclosed passageway. The clinic was located near the cafeteria in Building 1 and adjacent to the passageway connecting the two buildings.

You may qualify if:

• Eligible to receive a flu shot at Express Scripts.
• Over 18 years of age.

You may not qualify if:

• Children
• Non Express Scripts employees
