ABSTRACT: PURPOSE: Measles-mumps-rubella-varicella (MMRV) vaccine is associated with increased febrile seizure risk compared with measles-mumps-rubella and varicella vaccine given separately (MMR+V) in children 12-15-month old. We assessed knowledge regarding MMRV and febrile seizures, intended practices, and factors influencing the decision to recommend MMRV. METHODS: National survey administered 10/2008-1/2009 of US pediatricians (Peds) and family physicians (FP). RESULTS: Response rate was 73% (620/849). Twenty-nine percent of Peds and 74% of FP (p<0.001) were unaware of increased febrile seizure risk after MMRV. After reading an informational statement, 20% of Peds and 7% of FP (p<0.001) would recommend MMRV to a healthy 12-15-month-old child. The factor most frequently reported as "very important" in the decision to recommend MMRV or MMR+V was ACIP/AAFP/AAP recommendations (pediatricians, 77%, family physicians, 73%, p=0.08). CONCLUSIONS: After receiving data regarding febrile seizure risk after MMRV, few physicians report they would recommend MMRV to a healthy 12-15-month-old child.

ABSTRACT: To assess the effectiveness of reminder/recall (R/R) for immunizing adolescents in private pediatric practices and to describe the associated costs and revenues.
We conducted a randomized controlled trial in 4 private pediatric practices in metropolitan Denver. In each practice, 400 adolescents aged 11 to 18 years who had not received 1 or more targeted vaccinations (tetanus-diphtheria-acellular pertussis, meningococcal conjugate, or first dose of human papillomavirus vaccine for female patients) were randomly selected and randomized to intervention (2 letters and 2 telephone calls) or control (usual care) groups. Primary outcomes were receipt of >1 targeted vaccines and receipt of all targeted vaccines 6 months postintervention. We calculated net additional revenue for each additional adolescent who received at least 1 targeted vaccine and for those who received all targeted vaccines.
Eight hundred adolescents were randomized to the intervention and 800 to the control group. Baseline rates of having already received tetanus-diphtheria-acellular pertussis, meningococcal conjugate, and first dose of human papillomavirus vaccine before R/R ranged from 33% to 54%. Postintervention, the intervention group had significantly higher proportions of receipt of at least 1 targeted vaccine (47.1% vs 34.6%, P < .0001) and receipt of all targeted vaccines (36.2% vs 25.2%, P < .0001) compared with the control group. Three practices had positive net revenues from R/R; 1 showed net losses.
R/R was successful at increasing immunization rates in adolescents and effect sizes were comparable to those in younger children. Practices conducting R/R may benefit financially if they can generate additional well-child care visits and keep supply costs low.

ABSTRACT: Little is known about the effects of increased parental vaccine safety concerns on physicians' vaccine communication attitudes and practices.
To assess among pediatricians and family medicine (FM) physicians: (1) prevalence of parental requests to deviate from recommended vaccine schedules; (2) responses to such requests; and (3) attitudes about the burden and success of vaccine communications with parents.
Survey of nationally representative samples of pediatricians and FM physicians (N=696) conducted during February to May 2009 with analysis in 2010.
Response rates were 88% for pediatricians and 78% for FM physicians. Overall, 8% of physicians reported that ≥10% of parents refused a vaccine and 20% reported that ≥10% of parents requested to spread out vaccines in a typical month. More pediatricians than FM physicians reported always/often requiring parents to sign a form if they refused vaccination (53% vs 31%, p<0.0001); 64% of all physicians would agree to spread out vaccines in the primary series at least sometimes. When talking with parents with substantial concerns, 53% of physicians reported spending 10-19 minutes and 8% spending ≥20 minutes. Pediatricians were more likely than FM physicians to report their job less satisfying because of parental vaccine concerns (46% vs 21%, p<0.0001). Messages most commonly reported as "very effective" were personal statements such as what they would do for their own children.
The burden of communicating with parents about vaccines is high, especially among pediatricians. Physicians report the greatest success convincing skeptical parents using messages that rely on their personal choices and experiences.
