Outcome Measures

Primary Outcomes (1)

  • Child Immunization Status at 19 Months, 0 Days of Age Characterized as Percent Days Under-immunized (DUI)

    Immunization status was obtained from WA or CO state immunization registry or directly from participating practices. At enrollment, parent/infant dyads completed the Parental Attitudes about Childhood Vaccines short version (PACV-SF), a validated survey scored from 0 to 4. A score of 2 or more represented parent/infant dyad with negative vaccine attitudes. Among parent/infant dyads with negative vaccine attitudes, the child's immunization status at 19 months was calculated based on recommended ages and intervals between doses provided by ACIP for summing late days for each dose of the 8 routine vaccines recommended by 19 months (HepB, rotavirus, DTaP, Hib, pneumococcal conjugate, inactivated polio virus, MMR, and varicella). There was a max of 23 recommended doses for the 8 vaccines - doses varied depending on brand. Total max DUI was a sum of total possible days late for each dose through 19mo(2830 days).Percent DUI was calculated by dividing child's DUI by the total maximum DUI.

Secondary Outcomes (2)

  • Post-Visit Parental Satisfaction Survey Scored on a 7-point Likert Scale

    approximately 6 months post birth

  • Change in Clinician Self-Efficacy With Parent/Infant Dyads With Negative Vaccine Attitudes - Pre-vs Post-Surveys

    At Baseline and Post-Intervention (up to 2 years after baseline)

Study Arms (2)

PIVOT with MI

EXPERIMENTAL

Clinics in which the Presumptively Initiating Vaccines and Optimizing Talk with Motivational Interviewing (PIVOT-MI) communication strategy has been implemented.

Behavioral: Experimental: PIVOT with MI

Control

ACTIVE COMPARATOR

Clinics delivered standard care.

Other: Active Comparator: Control

Interventions

Providers in participating intervention clinics will be trained in the PIVOT-MI strategy in which a presumptive format is used to initiate the childhood vaccine recommendation with all parents followed by use of motivational interviewing (MI) with parents who voice resistance to that recommendation. Parent participants will receive PIVOT-MI.

PIVOT with MI

Providers at participating control clinics will deliver care as usual. Parent participants will receive standard care.
