Does health insurance coverage of office visits influence colorectal cancer testing?

OBJECTIVE: To assess the effect of differing health insurance coverage of physician office visits on the use of colorectal cancer (CRC) tests among an employed and insured population. METHOD: Cohort study of persons ages 50 to 64 years enrolled in fee-for-service (FFS) or preferred provider organization (PPO) health plans, where FFS plan enrollees bear disproportionate share of office visit coverage, for the period 1995 through 1999. RESULTS: Compared with FFS plans, enrollees in PPO plans were significantly more likely to obtain CRC tests [adjusted relative risk (RR(a)), 1.27; 95% confidence intervals (CI), 1.21-1.24]. The association was more pronounced among hourly individuals (RR(a), 1.43; 95% CI, 1.41-1.45) than among salaried individuals (RR(a), 1.09; 95% CI, 1.05-1.10), consistent with a greater differential in office visit coverage among the hourly group. CONCLUSIONS: Disproportionate cost-sharing seems to have a negative effect on the use of CRC tests most likely by discouraging nonacute care physician office visits.

Hospitalizations during pregnancy among managed care enrollees.

OBJECTIVE: To describe the prevalence of hospitalizations during pregnancy, the reason for hospitalization, the length of stay, and the associated costs. METHODS: We analyzed data from a national managed care organization and determined the occurrence of hospitalizations for 46,179 women who had a live birth or a pregnancy loss in 1997. RESULTS: Overall, 8.7% of women were hospitalized during their pregnancy. Of these, 5.7% were hospitalized and discharged while pregnant, 0.8% experienced extended stays before a live birth or pregnancy loss, and 2.1% experienced pregnancy loss. Hospitalizations were more common among younger women, women with multiple gestations, and women in the northeastern United States. Women who had a live birth were primarily hospitalized for preterm labor (24%), hyperemesis (9%), hypertension (9%), kidney disorders (6%), and prolonged premature rupture of membranes (6%). Charges totaled over $36 million. CONCLUSION: Antenatal hospitalizations are common.
