Impact of the 2022 Infant Formula Shortage on Neonatal Intensive Care Units.

Objective: The aim of this study was to examine effects of the 2022 infant formula shortage as experienced by neonatal intensive care units (NICUs) in the United States, a previously unreported perspective. Methods: A mixed-method approach was utilized. Data were collected using an online survey of NICU medical directors. Quantitative data were analyzed with descriptive statistics and Student's t test. Thematic analysis was utilized to make sense of patterns within the qualitative data. Results: Responses from 139 medical directors were received. Both academic (41.7%) and community (58.3%) NICUs were represented among respondents. Thirty-nine percent of NICU medical directors reported an impact on their unit by the infant formula shortage. Within the qualitative data four themes were revealed as follows: alterations to discharge planning, policy modifications, suboptimal solutions, and extraordinary measures. These themes may inform strategies for mitigation of future infant formula shortages. Conclusions: NICUs were significantly impacted by the infant formula shortage with likely lasting effects. From the reported experiences, clear recommendations have been formed to minimize effects of future infant formula shortages.
