mPINC Methods
In 2007, CDC administered the first mPINC survey. The survey went to every birth facility in the United States and territories that routinely provided maternity care services.
The initial survey established practice and policy measures related to breastfeeding at hospitals providing maternity care. CDC administered the survey every other year from 2007 to 2015 to monitor and examine changes in practices over time. After the 2015 administration, CDC redesigned the survey to reflect changes in maternity care practices over the past decade. The redesigned survey launched in 2018.
Survey administration
CDC's contractor, Abt Global, begins survey administration by emailing or calling each hospital that participated in the previous mPINC survey. Abt Global uses the email address or phone number of the person who submitted the previous survey. If you would like to update the mPINC survey point of contact at your hospital, please email the business contact information for this person – including name, phone number, and hospital name and address – to mPINC@cdc.gov.
CDC's contractor then screens all other hospitals. The contractor calls the hospital's switchboard and asks to be transferred to the lactation services coordinator, mother-baby nurse manager or labor and delivery unit manager. Once the contractor identifies the best person to complete the survey, they will email the mPINC survey screening link to determine eligibility. Eligible hospitals will then be taken to the survey, which includes questions about infant nutrition, such as breastfeeding, using formula to feed healthy newborns, and feeding routines.
Although CDC's contractor will attempt to contact the person who submitted the survey in the previous cycle, the person identified to receive the survey one year is not necessarily the person identified to receive the survey in a later cycle.
To ensure survey validity, CDC follows the same protocol to identify survey recipients at each hospital as described above.
