Understanding newborn infant readmission: findings of the Ontario Mother and Infant Survey.

The Ontario Mother and Infant Survey examined health and social service utilization of postpartum women and newborn infants from five hospital sites. A cross-sectional multilanguage survey design with longitudinal follow-up was used: 1,250 eligible, consenting women completed a self-report questionnaire in hospital and 875 women participated in a structured telephone interview at four weeks post-discharge. Rates of newborn infant readmission ranged from 2.4% to 6.7%. The best predictors of readmission were: main source of household income was other than employment; maternal self-rating of health was poor; mother anticipated inadequate help and support at home following discharge; mother received help from friends/neighbours following discharge; and mother had concern about infant care and behaviour. Readmission was not associated with length of postpartum hospital stay. The study findings suggest that there is a complex relationship between infant health care needs, family resources and provider practices that produces clinically important, site-specific readmission patterns.
