RESUMEN
OBJECTIVE: To assess risk factors associated with loss to follow up in patients referred for colposcopy after abnormal cervical cytology during pregnancy in a Southern safety net hospital population. METHODS: An urban colposcopy center was queried for patients referred for follow up of abnormal cervical cytology during pregnancy and the postpartum period. Patients were identified through a standardized referral code in the electronic medical record. Multivariable logistic regression was used to compare patient characteristics between those who followed up for colposcopy and those lost to follow up. Independent risk factors assessed included age, parity, race, insurance, HIV status, history of mental illness, BMI, gestational age and trimester at screening, cytology at colposcopy referral, interval days until colposcopy, and biopsy histology. RESULTS: 1063 patients were identified, with 40.8% of patients who completed referred colposcopy. Patient characteristics predictive for colposcopy follow up included: maternal age at referral cervical cytology >30 years (1.67; 1.27-2.20; < 0.003), gestational age < 18 weeks at abnormal cervical cytology (1.57; 1.23-2.01; <0.0002), maternal race non-African American (2.20; 1.32-3.65; <0.0024) and with high grade cervical cytology (2.42; 1.81-3.24; <0.0001). CONCLUSION: In this population, inadequate follow up for abnormal cervical cytology during pregnancy is prominent, especially among those with younger maternal age, African American (AA) race, cervical cytology completed at later gestational ages of pregnancy, and low-grade initial cytology. Higher no-show rate among AA patients supports well-documented health disparities and need for further investigation and protocols to identify those at risk for loss to follow up.
