Characteristics Associated with Participant Attrition and Retention in a Perinatal Home Visiting Program.

Using data from the Florida Maternal, Infant, and Early Childhood Home Visiting (MIECHV) funded programs, we examined program- and participant-level characteristics associated with participant retention by time of enrollment. Analyses of data for 1,807 women enrolled in 11 sites across three years included descriptive statistics; Kaplan-Meier survival curve estimation and multilevel survival analyses using shared frailty model to assess participant- and program-level characteristics overall and by time of enrollment (during pregnancy or post-delivery). Median retention time for MIECHV participants was 462 days. The primary reason for attrition was loss-to-follow-up (59.4%) due to change of address/telephone. We found participant age > 25 years (compared to < 20 years), enrollment during pregnancy, and an average of 1.5-2.0 home visit/month to be protective, while current/history of substance abuse was a risk factor for attrition. To improve participant retention, the Florida MIECHV program may need to bolster efforts to support housing stability, increase outreach and engagement to younger women, address barriers to achieving two home visits per month throughout the program, and target differential predictors of participant attrition depending on time of enrollment.
