The aim of the study was to estimate the excess cost of guideline nonadherent cervical cancer screening in women beyond the recommended screening ages or posthysterectomy in a single healthcare system.Materials and Methods
All Pap tests performed between September 1, 2012, and August 31, 2014, in women younger than 21 years, older than 65 years, or after hysterectomy, were coded as guideline adherent or nonadherent per the 2012 America Society of Colposcopy and Clinical Pathology guidelines. We assumed management of abnormal results per the 2013 America Society of Colposcopy and Clinical Pathology management guidelines. Costs were obtained from a literature review and Center for Medicare and Medicaid Services data and applied to nonadherent screening and subsequent diagnostic tests.Results
During this period, 1,398 guideline nonadherent Pap tests were performed (257 in women <21 years, 536 in women >65 years, and 605 after hysterectomy), with 88 abnormal results: 35 (13.5%) in women younger than 21 years, 14 (2.6%) in women older than 65 years, and 39 (6.5%) in women after hysterectomy. The excess cost for initial screening, diagnostic tests, and follow-up was US $35,337 for 2 years in women younger than 21 years, US $54,378 for 5 years in women older than 65 years, and US $77,340 for 5 years in women after hysterectomy, resulting in a total excess cost of US $166,100 for 5 years. Of the 1,398 women who underwent guideline nonadherent screening, there were only 2 (0.1%) diagnoses of high-grade dysplasia (VaIN3).Conclusions
Guideline nonadherent cervical cancer screening in women beyond the recommended screening ages and posthysterectomy resulted in costs exceeding US $160,000 for screening, diagnostic tests, and follow-up with minimal improvement in detection of high-grade dysplasia.
