Understanding physician agreement with varicella immunization guidelines.

Background: Although varicella vaccine was licensed in 1995, immunization rates are only moderate. This study identifies factors associated with physician self-reported likelihood of recommending varicella vaccination to patients.

Methods: Two hundred eighty-one Minnesota and Pennsylvania primary care physicians who participated in surveys on barriers to vaccination in 1990-1991 and 1993 were surveyed in 1999, assessing physicians' beliefs about varicella disease and vaccine and their self-reported likelihood of recommending varicella vaccine to three age groups of children.

A comprehensive investigation of barriers to adult immunization: a methods paper.

Objective: Immunization rates for influenza and pneumococcal vaccines among the elderly (especially minority elderly) are below desired levels. We sought to answer 4 questions: (1) What factors explain most missed immunizations? (2) How are patient beliefs and practices regarding adult immunization affected by racial or cultural factors? (3) How are immunizations and patient beliefs affected by physician, organizational, and operational factors? and (4) Based on the relationships identified, can typologies be created that foster the tailoring of interventions to improve immunization rates?

Study Design: A multidisciplinary team chose the PRECEDE-PROCEED framework, the Awareness-to-Adherence model of clinician response to guidelines, and the Triandis model of consumer decision making as the best models to assess barriers to and facilitators of immunization. Our data collection methods included focus groups, face-to-face and telephone interviews, self-administered surveys, site visits, participant observation, and medical record review.

Effect of the Vaccines for Children program on physician referral of children to public vaccine clinics: a pre-post comparison.

Objective: Started in late 1994, the Vaccines for Children (VFC) program is a major entitlement program that provides states with free vaccines for disadvantaged children. Some evaluation studies have been conducted, but they do not include individually matched pre-post comparisons of physician responses. This project studied the effect of the VFC on the physician likelihood of referring children to public vaccine clinics for immunizations.

Does the Vaccines for Children program influence pediatric nurse practitioner referral of disadvantaged children to public vaccine clinics?

Objective: Concerns about financial barriers to vaccination led to the creation of the Vaccines for Children (VFC) program, which provides free vaccines to states for disadvantaged children. Our objective was to understand the effect of free vaccine and insurance on pediatric nurse practitioners' (PNPs) likelihood of referring children to public vaccine clinics. Although referral from the medical home to public vaccine clinics is preferable to not vaccinating, there are disadvantages, including the potential for windows of inadequate protection and fragmentation of care.
