Term: Newborn Readmission Rate
Last Updated: 2010-08-12
In Brownell et al. (2001), this is calculated as the ratio of infants with a hospital stay taking place more than one day after discharge from the birth hospital stay, to the number of live born infants who were discharged from their birth hospital stay alive.
In Brownell et al. (2008), this is calculated by taking the number of infants who have a hospital stay anywhere from 1 to 28 days after discharge from their birth hospitalization and dividing by the total number of infants who have been discharged alive from their birth hospitalization. For a list of ICD-9-CM and ICD-10-CA diagnoses codes used to identify newborn readmissions in the Child Health Atlas Update (2008), please see the Links section below.
In Martens et al. (2010), this was defined as the crude annual rate of infant readmission to the hospital within four weeks of hospital discharge of birth hospitalization. It was measured over five calendar years. One baby could potentially have more than one readmission, hence this is a rate not a prevalence. The denominator includes all live births (in hospital) in the study period.
