Further study details as provided by University of Kansas Medical Center:

Primary Outcome Measures:
  • the first aim is to assess our ability to enroll at least 70% (N=90) of eligible parents in a text messaging program [ Time Frame: up to 1 year ]
    This will be accomplished through recruitment of parents of newborns at Wesley Medical Center who will receive care from Carriage Park Clinic.

Secondary Outcome Measures:
  • the second aim is to implement the TRICKs intervention with parents of newborns. [ Time Frame: up to 1 year ]
    SMSCaster software will be assessed for its ability to send appointment reminders and to collect follow-up data from parents regarding whether immunization appointments were scheduled.

  • the third aim is to collect immunization information on participant's children. [ Time Frame: up to 1 year ]
    This will be accomplished using the Kansas Immunization Registry (KSWebIZ), a web-based centralized birth to death database that maintains complete, accurate, and secure immunization records for all Kansas residents.

Enrollment: 90
