To assess the cost effectiveness of various strategies of screening for open angle glaucoma.
A decision analysis model using TreeAge Pro software was created to compare screening of at risk subjects using strategy combination of different strategies screening methods including Frequency Doubling Technology perimeter (FDT), scanning laser ophthalmoscopy (HRT3). We simulated one screening session in a population composed of 10,000 at risk subjects. Data input of cost and effectiveness of the devices were extracted from the Mobile glaucoma screening project in high risk populations and the Régie de l’assurance maladie du Québec (RAMQ).
Our cost-effectiveness model demonstrated that the cost for using combination strategy including tonometry and HRT3 as screening tools was estimated at $CA 412,233, and detected a total of 350 true cases per 10,000 screened subjects (C/E ratio of $CA 1178 per true case detected). The use of tonometry and visual field (FDT) for screening purpose had a cost of $CA 269,633 and 410 true cases per 10,000 screened subjects. Finally, combining tonometry, FDT and HRT3 results of cost of $CA 571 633 with 286 true cases detected
Screening with tonometry and FDT would imply additional cases detected compared to tonometry and HRT. Further studies are needed to determine the best way to integrate these findings in a national screening programme.
