Brief Summary:
The primary aim of this trial is to test the effectiveness of an intervention to train primary care physicians to determine if it leads to decreased parental vaccine hesitancy.

Condition or disease Intervention/treatment Phase
Childhood Vaccination Behavioral: Academic Detailing Not Applicable

Detailed Description:
The primary aim of this trial is to test the effectiveness of an intervention to train primary care physicians to determine if it leads to decreased parental vaccine hesitancy. The investigators will train primary care teams with an initial training followed by telephone coaching and follow-up visits, and assess the outcomes of parental vaccine hesitancy (primary) and physician self-efficacy (secondary) at baseline and 6 months.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 491 participants

Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Health Services Research
Official Title: Vaccine Hesitancy Intervention--Provider (VHIP)
Study Start Date : February 2012
Actual Primary Completion Date : October 2013
Actual Study Completion Date : April 2014

Arm Intervention/treatment
Experimental: Intervention Clinics
Providers in intervention clinics will receive a training followed by telephone coaching and follow-up visits for six months.
Behavioral: Academic Detailing
The intervention design is based on "academic detailing," an effective method of changing physician behavior. The aim of the training is effective communication with parents who are hesitant about childhood vaccinations.
No Intervention: Control Clinics
Control clinics will receive all intervention materials at the completion of the study.



Primary Outcome Measures :
  1. Parental Vaccine Hesitancy Measure [ Time Frame: Change from Baseline in Parental Hesitancy at 6 months ]
    The investigators will contact mothers of newborns in study practices and conduct a telephone survey at two time points: baseline and 6 months. Surveys will assess parental hesitancy, parental trust in provider, and other covariates such as perceived social norms, other sources of information about vaccines, and demographic information.


Secondary Outcome Measures :
  1. Physician Self Efficacy Measure [ Time Frame: Change from Baseline in Physician Attitudes at 6 months ]
    Assessed via self-administered surveys of providers in all participating clinics at baseline and 6-months. The investigators will measure physician attitudes, perceived norms, intentions to change behavior, practice characteristics, and physician demographics.
