Does parental report of insurance status agree with hospital administrative data for children presenting to the ED?

Insurance-Based Differences in Time to Diagnostic Follow-up after Positive Screening Mammography

BACKGROUND

Insurance may lengthen or inhibit time to follow-up after positive screening mammography. We assessed the association between insurance status and time to initial diagnostic follow-up after a positive screening mammogram.

METHODS

Using 1995-2010 data from a North Carolina population-based registry of breast imaging and cancer outcomes, we identified women with a positive screening mammogram. We compared receipt of follow-up within 60 days of screening using logistic regression and evaluated time to follow-up initiation using Cox proportional hazards regression.

RESULTS

Among 43,026 women included in the study, 73% were <65 years and 27% were 65+ years. Median time until initial diagnostic follow-up was similar by age group and insurance status. In the adjusted model for women <65, uninsured women experienced a longer time to initiation of diagnostic follow-up [HR, 0.47; 95% confidence interval (CI), 0.25-0.89] versus women with private insurance. There were increased odds of these uninsured women not meeting the Centers for Disease Control and Prevention guideline for follow-up within 60 days (OR, 1.59; 95% CI, 1.31-1.94). Among women ages 65+, women with private insurance experienced a faster time to follow-up (adjusted HR, 2.09; 95% CI, 1.27-3.44) than women with Medicare and private insurance. Approximately 10% of women had no follow-up by 365 days.

CONCLUSIONS

We found differences in time to initial diagnostic follow-up after a positive screening mammogram by insurance status and age group. Uninsured women younger than 65 years at a positive screening event had delayed follow-up.

The State Children's Health Insurance Program: a multicenter trial of outreach through the emergency department

OBJECTIVES

We evaluated emergency department (ED)-based outreach for the State Children's Health Insurance Program (SCHIP).

METHODS

We conducted a multicenter trial among uninsured children (< or = 18 years) who presented to 5 EDs in 2001 and 2002. On-site staff enrolled consecutive subjects for a control period followed by an intervention period during which staff handed out SCHIP applications to the uninsured. The primary outcome was state-level confirmation of insured status at 90 days.

RESULTS

We followed 223 subjects (108 control, 115 intervention) by both phone interview and state records. Compared to control subjects, those receiving a SCHIP application were more likely to have state health insurance at 90 days (42% vs 28%; P<.05; odds ratio [OR]=3.8; 95% confidence interval [CI]=1.7, 8.6). Although the intervention effect was prominent among 118 African Americans (50% insured after intervention vs 31% of controls, P<.05), lack of family enrollment in other public assistance programs was the primary predictor of intervention success (OR=3.7; 95% CI=1.6, 8.4).

CONCLUSIONS

Handing out insurance applications in the ED can be an effective SCHIP enrollment strategy, particularly among minority children without connections to the social welfare system. Adopted nationwide, this simple strategy could initiate insurance coverage for more than a quarter million additional children each year.
