Interdisciplinary Quality Improvement Project Increases Vitamin D Supplementation in Infants

BACKGROUND: American Academy of Pediatrics guidelines recommend 400 IU of vitamin D supplementation daily for certain infants <1 year of age. We aimed to increase the proportion of reported appropriate vitamin D supplementation for infants born at our institution and those who followed up in our resident clinic through 6 months from 49% to 80% over 24 months. METHODS: Our interdisciplinary quality improvement effort included vitamin D medication delivery before nursery discharge and family and staff education. The process measure was the percentage of families discharged from birth hospitalization with vitamin D and teaching. The outcome measure was the percentage of families reporting appropriate vitamin D supplementation at 2-, 4-, and 6-month well child visits. The balancing measure was the percentage of infants discharged from the nursery by 2 pm. Data were displayed on Statistical Process Control p charts and established rules for detecting special causes were applied. RESULTS: Baseline and improvement data were collected for 587 hospital discharges and 220 outpatient encounters. The percentage of families discharged with vitamin D increased from 24.8% to 98% from 2016 to 2018. Percent of families reporting appropriate vitamin D supplementation at well child visits increased from 49% to 89% from 2016 to 2018. Overall, the percentage of discharges by 2 pm remained stable at 60%. CONCLUSION: Bedside medication delivery and education in the newborn nursery improved reported vitamin D supplementation rates in the first 6 months of life. The intervention did not delay newborn hospital discharge.
