BACKGROUND Despite the widespread use of Papanicolaou (Pap) smear screening, substantial morbidity and mortality from cervical carcinoma continue in the U.S. Although access to screening is a major barrier to use of the Pap smear, invasive cervical carcinoma (ICC) still is observed in health plan members who have comprehensive preventive care coverage. METHODS For all women diagnosed with ICC between 1988 and 1994 in a large prepaid health plan, the authors retrospectively reviewed the medical records for prediagnosis Pap smear history to identify antecedents to ICC. RESULTS Of 642 women diagnosed as having ICC, 455 (71%) had been plan members for ≥ 30 of the 36 months before diagnosis. Of these 455 women, 240 (53%) had no Pap smear during the 6–36 months prior to diagnosis (i.e., were nonadherent to screening), 127 (28%) had only “normal” Pap smear results, 42 (9%) had at least 1 abnormal Pap smear and were adequately followed, 17 (4%) had at least 1 abnormal result without adequate follow‐up, and 29 (6%) were classified as “other.” Compared with adherent women, more nonadherent women presented with later stage disease, were symptomatic at the time of diagnosis, were older, and were of a race/ethnicity other than non‐Hispanic white. CONCLUSIONS Nonadherence to screening recommendations was found to be the most important modifiable antecedent to ICC in this population. The rate of incidence of ICC could be reduced by interventions to increase screening in women who do not have Pap smears regularly and by the use of newer screening technologies to reduce the false‐negative rate of Pap smears.

In this study of hospital discharge data on births to residents of an eight-county region of California, we found an increasing lack of health insurance that was associated with an elevated and increasing risk of adverse outcomes in newborns. Between 1982 and 1986, the percentage of newborns without health insurance increased overall by 45 percent (from 5.5 to 8.0 percent; P less than 0.001); the increases were larger among Asians (by 54 percent [from 7.8 to 12.0 percent]; P less than 0.001) and Latinos (by 140 percent [from 8.2 to 19.7 percent]; P less than 0.001). By 1986, the odds ratio for an adverse hospital outcome (defined as a prolonged hospital stay, transfer of the newborn to another institution, or death) was 1.31 (95 percent confidence interval, 1.17 to 1.46) in uninsured as compared with privately insured newborns, with control for race or ethnic group. There was a significant increase in risk over time (P less than 0.03); the comparable odds ratios in 1982 and 1984 were 1.11 (95 percent confidence interval, 0.93 to 1.33) and 1.19 (1.05 to 1.35), respectively. In 1986 the risks were especially elevated for uninsured as compared with privately insured blacks and Latinos (odds ratios, 2.24 [95 percent confidence interval, 1.60 to 3.13] and 1.56 [1.26 to 1.94], respectively); the increases in risk over time were the most marked in these groups. We believe that the elevated and increasing risks for uninsured newborns are explained at least in part by inadequate and diminishing access to care and that this burden is borne disproportionately by blacks and Latinos.

The disproportionate burden of cervical cancer observed in older women appears to be largely attributable to lack of screening within the 3 years before diagnosis.
