Evaluation of a Cervical Cancer Screening Intervention for Prison Inmates

Background: Female prison inmates are underscreened and are at higher risk of cervical cancer. The impact of a nurse-led Pap screening intervention was examined, which included information sessions and Pap testing clinics. Method: Pap screening rates for 650 inmates at the Burnaby Correctional Centre for Women were compared both before and during the 20-week intervention period. These rates were determined by record linkage of Correction Branch inmate records and Cervical Cancer Screening Program patient records. Associations between socio-demographic factors and Pap screening rates were also examined. Results: A higher proportion of inmates was screened during the intervention period (26.9%) than during the preintervention period (21.0%) (although the difference was not statistically significant (p=0.06)). Very short-stay inmates were less frequently screened in the preceding two years before the intervention. Inmates with no high school education and longer lengths of incarceration were significantly more likely to receive Pap testing during the intervention period as compared to the preintervention period. Conclusion: The nurse-led intervention resulted in a modest improvement in the proportion of inmates receiving Pap screening. Unfortunately, the benefit of the nurse clinician did not reach, to a greater extent, inmates who had not been previously screened or who were inadequately screened. There is need for further work to target this hardest-to-reach group.
