Patients who accumulate multiple emergency department visits and hospital admissions, known as super-utilizers, have become the focus of policy initiatives aimed at preventing such costly use of the health care system through less expensive community- and primary care-based interventions. We conducted cross-sectional and longitudinal analyses of 4,774 publicly insured or uninsured super-utilizers in an urban safety-net integrated delivery system for the period May 1, 2011-April 30, 2013. Our analysis found that consistently 3 percent of adult patients met super-utilizer criteria and accounted for 30 percent of adult charges. Fewer than half of super-utilizers identified as such on May 1, 2011, remained in the category seven months later, and only 28 percent remained at the end of a year. This finding has important implications for program design and for policy makers because previous studies may have obscured this instability at the individual level. Our study also identified clinically relevant subgroups amenable to different interventions, along with their per capita utilization and costs before and after being identified as super-utilizers. Future solutions include improving predictive modeling to identify individuals likely to experience sustained levels of avoidable utilization, better classifying subgroups for whom interventions are needed, and implementing stronger program evaluation designs.

This study explores rates of early pregnancy and parenthood among a sample of young adults ( N = 215), ages 18-22, with a history of foster care. The study also compares the educational attainment, financial resources, and homelessness experiences of young adults who became parents to those who did not. By age 21, 49% of the young women became pregnant, and 33% of young men reported getting someone pregnant. Over a quarter of participants experienced parenthood, which was associated with lower educational attainment, less employment, not having a checking or savings account, and a history of homelessness. Gender moderated the association between parenthood and employment such that males who were parents were more likely than female parents to be employed. Given that these young adults were at risk of early pregnancy and parenthood regardless of emancipation status and across several racial/ethnic groups, the results suggest a need for early pregnancy prevention efforts for all youth with child welfare involvement as well as improving resources and support for those who become young parents.
