Cost-Effectiveness Of Cervical Cytologic Examination During Pregnancy

Background: We undertook a study to determine the cost-effectiveness of performing routine cervical cytologic examination during pregnancy. Methods: The costs generated by doing routine prenatal cervical cytologic examination were calculated based on chart review in a family practice setting. A consecutive sample of 523 patients giving birth during 1990 was used. Analysis was done on 423 of those patients with prenatal Papanicolaou smear results recorded. Cost savings from detection of curable disease and utility of the test in terms of well-years saved were calculated from published statistics using a single-step Markov process to model the population at risk. Results: For patients of all ages using a discount rate of 5 percent, the cost generated by prenatal cervical cytologic examination was $146,400 per well-year of life saved. Age stratification showed cost per well-year to range from $321,600 for patients aged 15 to 19 years to $48,800 for those aged 35 to 39 years. Conclusions: Routine prenatal cervical cytologic examination is significantly less cost-effective than the most commonly done medical procedures. If medical funding is limited, elimination of this test should be considered for women with normal findings on cervical cytologic examinations within the previous 2 to 3 years.
