Adult Caregiver Influenza Vaccination Through Administration in Pediatric Outpatient Clinics: A Cocooning Healthcare Improvement Project.

Background: Pediatric exposure to influenza-infected adult caregivers (AC) is a significant risk factor for developing influenza. Poor access to vaccines contributes to low adult vaccination rates. We offered adult vaccination at regularly scheduled pediatric office visits and examined barriers to improve future vaccination rates.

Methods: Via a retrospective chart review, we identified ACs who received an influenza vaccination at 1 of 3 pediatric clinics within an academic center from August 2015 to May 2016. We screened for demographics of ACs and their children. Rates of AC vaccination and AC refusal were not measured.

Results: A total of 297 ACs representing 518 children received their influenza vaccine at their child's pediatric office. The mean age of ACs was 35.9 years (range, 22-70 years) and 68.5% were mothers. Most ACs (n = 294, 99%) receiving the vaccine had private insurance. Almost all ACs received their vaccination on the day of the child's visit (n = 250, 84%). A total of 49.6% of AC's children had high-risk illnesses. Parents of children with Medicaid were under-represented because of high parental copays (n = 3, 1%). The highest clinic vaccine participation was noted at the clinics with lowest Medicaid populations.

Conclusions: ACs readily accepted influenza vaccination at their child's pediatric primary care office. Increased vaccination acceptance occurred when ACs were female, had private insurance, if their child had a chronic illness and if the vaccination was offered the same day as their child's appointment. Likely reason for low acceptance in ACs with Medicaid insurance is high cost; thus, staff, well-aware of Medicaid's nonreimbursement, likely offered the vaccine less to these parents.
