Influenza vaccination in the 2009-2010 pandemic season: the experience of primary care physicians.

Objectives: Determine among a representative sample of pediatricians (Peds), family medicine (FM), and general internal medicine (GIM) physicians in the 2009-2010 influenza season physicians': 1) practices and experiences with delivery of seasonal and pH1N1 influenza vaccines; and 2) anticipated and experienced barriers.

Methods: Two US national surveys administered 7/2009-10/2009 (before pH1N1 distribution) and 3/2010-6/2010 (after pH1N1 distribution) to 416 Peds, 424 FM and 432 GIM.

Results: Of respondents who received both surveys, 62% (776/1253) completed both. Overall, 98% reported administering seasonal influenza vaccine and 86% pH1N1, with 70% reporting that working with public health in delivery of pH1N1 was a positive experience. Due to limited supplies of pH1N1, 63% of providers reported prioritizing who received vaccine even within high risk groups. Pre-distribution, 71% perceived that patient/parental safety concerns about pH1N1 would be a barrier, and post-distribution 72% perceived it had been a barrier. Physician concern about safety decreased, with 44% reporting safety a barrier pre-distribution and 12% post-distribution (p<0.001).

Conclusions: In the setting of a pandemic most primary care physicians collaborated with public health in delivery of pH1N1. Physicians faced challenges with patient/parent safety concerns about pH1N1 and supply issues with pH1N1 that required physicians to prioritize who received vaccine.
