The 2024 mPINC Survey is in the field!

We are now halfway through the data collection period for CDC’s 2024 Maternity Practices in Infant Nutrition and Care (mPINC) survey!

Battelle, the contractor conducting the mPINC survey on CDC’s behalf, is in the process of calling hospital switchboards and asking to be connected to the mother-baby nurse manager or, if not available, the manager for the labor and delivery unit. Battelle is still in the process of making these screening phone calls to determine whether a hospital is eligible to complete the survey, and if so, obtain the email address for the best point of contact to email a hospital-specific link to the survey.

Every hospital in the United States and territories that routinely provides maternity care services has been called at least once by Battelle. If you have not heard from Battelle, please check with your managers/leadership, lactation specialists, and maternity staff to see if anyone has received a call or voice mail from Battelle. If not, please send an email to with your hospital’s full name and address.

Please do not contact Battelle directly unless your hospital has received the survey link and you have a question related to the mPINC survey.

We are halfway through the data collection period for CDC’s 2024 mPINC survey.  Although we do not have a final submission deadline yet, we encourage hospitals to submit their surveys as soon as possible after receiving the invitation.

General mPINC Information

What is mPINC?

The CDC’s national survey of Maternity Practices in Infant Nutrition and Care (mPINC) assesses maternity care practices and provides feedback to encourage hospitals to make improvements that better support breastfeeding. About every 2 years, the CDC invites all hospitals across the country to complete the mPINC survey. The questions focus on specific parts of hospital maternity care that affect how babies are fed.

Why does mPINC exist?

Doctors, nurses, and hospital administrators can use mPINC data to improve care practices and policies to better support their maternity patients. the CDC sends a report to every participating hospital showing specific changes they can make to support breastfeeding mothers. State health departments and other stakeholders can use mPINC data to work together with partner agencies, organizations, policy makers, and health professionals to improve evidence-based maternity care practices and policies at hospitals in their state.

What is the process like?

Each time a new survey is administered the CDC calls the hospital switchboard and ask for the mother-baby nurse manager or, if not available, for the manager of the labor and delivery unit. After determining eligibility, that manager is asked to identify the best person to complete a survey that includes questions about infant nutrition, such as breastfeeding, using formula to feed healthy newborns, and feeding routines. The CDC calculates a total mPINC score for every participating hospital to indicate its overall level of maternity care practices and policies that support optimal infant feeding. A total mPINC score is provided in the individual hospital reports. Subscores further categorize maternity care practice subdomains. Responses are scored using an algorithm that denotes the evidence and best practices to promote optimal infant feeding within the maternity care setting. Possible scores range from 0 to100, with higher scores indicating better maternity care practices and policies.

How to see my facility's score?

An electronic version of each hospital’s report was sent to the work e-mail of the survey recipient in June 2020. If you are unable to locate your hospital’s mPINC report, please e-mail with your request and include the hospital name and address.
