Addressing the cervical cancer burden in the Rio Grande Valley of Texas through a multi-component program to improve...

Cervical cancer is preventable by following guidelines for vaccination, screening, diagnosis and treatment of preinvasive cervical lesions. We implemented a multicomponent intervention to increase rates of colposcopy after abnormal screening results in three clinic systems in the Rio Grande Valley, along the Texas-Mexico border. The goal of this study was to assess the outcomes of this program including participation in colposcopy within 90 days of screening for women with abnormal screening results, and the time between screening and colposcopy appointments during the first year (Year 1/baseline) and subsequent years (Years 2 through 4) of program implementation.

We performed a retrospective cohort analysis of medical records of clinics participating in the program. We utilized multiple logistic regression and linear regression to assess the colposcopic outcomes of women with indication for colposcopy.

A total of 1556 of the 14,846 (10.5 %) women who had undergone cervical cancer screening had abnormal results and met the criteria to be referred for colposcopy. There was a significant increase in the proportion of women who underwent colposcopy (within 90 days of screening) from Year 1/baseline (82.7 %) to Year 2 (90.6 %), OR= 1.65, p-value< 0.05. Similarly, the mean interval from screening to colposcopy decreased significantly from baseline (79 days) to Year 2 (49 days), to Years 3 and 4 (40 and 41 days, respectively), p < 0.001.

Our results suggest that multicomponent interventions can improve and sustain appropriate and timely colposcopy among women in medically underserved regions, improving cervical cancer prevention efforts in resource-limited settings.
