BACKGROUND: The aim of the study was to compare the cost effectiveness of immediate diagnosis and treatment of mild dyskaryosis compared with the usual policy of cytological surveillance.
METHODS: A cost effectiveness analysis was carried out alongside a randomized clinical trial.
RESULTS: Immediate diagnosis and treatment increased total costs by 50 per cent from £54.42 per treated woman [95 per cent confidence interval (CI) £48.85£59.98] in the surveillance group to £82.02 per woman in the immediate diagnosis and treatment group with an incremental cost of £27.60 (95 per cent CI £22.04£33.17). However, the number of cases of CIN III detected increased by 69 per cent for the policy of immediate diagnosis and treatment. This led to an average cost effectiveness ratio of £180.18 for the immediate diagnosis and treatment group and £199.94 per case of CIN III detected for the surveillance group, with a marginal cost effectiveness ratio of £148.22 (95 per cent Cl £94.01£309.33) for the immediate diagnosis and treatment group.
CONCLUSION: Immediate diagnosis and treatment increases the total cost of managing mildly dyskaryotic smears but this increased cost is offset by a sharp increase in the number of cases of CIN III detected.
