Patient Adherence to Follow-Up Recommendations Following Cryotherapy for Treatment of High-Grade Cervical Dysplasia.

Objective Determine the rate of patient adherence to follow-up recommendations after cryotherapy for high-grade cervical lesions, and identify patient characteristics associated with adherence to follow-up. Methods This is a retrospective case series from May 2016 to June 2018 of patients who underwent cryotherapy for high-grade dysplasia at a single academic safety-net hospital. Patient demographics and clinical information were abstracted from the electronic medical record. All patients were recommended to follow up with Pap and high-risk human papillomavirus (HPV) testing 12 months after their procedure. The primary outcome was patient adherence to these recommendations. Descriptive statistics and statistical testing were utilized to compare adherence by demographic and clinical characteristics. A multivariable logistic model was used to preliminarily look at potential factors associated with increased odds of adherence. We further described the proportion of follow-up testing among those patients who adhered to recommendations. Results One hundred and forty-three patients met the inclusion criteria. The adherence percentage was 60.1% (95% CI: 51.6, 68.2). Only employment was associated with follow-up among demographic variables reviewed (p=0.039). Of those who were adherent with follow-up, 4.7% (4/86) had high-grade findings on follow-up Pap testing, and 56.9% (49/86) had negative cytology and negative HPV testing. Conclusion Adherence to follow-up recommendations for the following cryotherapy for high-grade dysplasia within our system was poor, and demographic factors were generally not associated with adherence to follow-up. Given these findings, cryotherapy should be used with caution.
