BackgroundTummy time enhances motor development, improves mobility, strength, and head clearance, reduces cranial asymmetry, and decreases the risk of childhood obesity. The American Academy of Pediatrics (AAP) advises all infants, beginning at birth, partake in supervised daily tummy time during awake periods. Since 1994, when the AAP initiated the “Back to Sleep” campaign, the number of infants participating in daily tummy time has significantly declined, leading to an increase in adverse outcomes. MethodsUsing a quasi-experimental design, tummy time guidelines were implemented in a rural family primary care practice to support infant development. This three-phase intervention included educating providers, developing a smart phrase, and posting visual reminders. A convenience sample of infants who presented for well-visits at a rural family practice in southwestern Washington were included in this project. The Survey of Wellbeing of Young Children measurement tool was used to collect infant developmental outcome data. FindingsFollowing the intervention, infant developmental outcomes improved. There was a 10% reduction at two months of age and a 7% reduction at four months of age in the number of infants with below average developmental scores. DiscussionThis project demonstrates that increased provider awareness and implementation of tummy time clinical practice guidelines can benefit infant development in primary care, especially in rural populations. Application to practiceViable strategies for incorporating clinical practice guidelines into primary care are presented.
