Economic evaluation of screening for open-angle glaucoma.

Objectives: The aim of this study was to assess the cost-effectiveness of screening for open-angle glaucoma (OAG) in the United Kingdom, given that OAG is an important cause of blindness worldwide.

Methods: A Markov model was developed to estimate lifetime costs and benefits of a cohort of patients facing, alternatively, screening or current opportunistic case finding strategies. Strategies, varying in how screening would be organized (e.

Economic evaluation of laparoscopic surgery for colorectal cancer.

Objectives: The aim of this study was to assess the cost-effectiveness of laparoscopic surgery compared with open surgery for the treatment of colorectal cancer.

Methods: A Markov model was developed to model cost-effectiveness over 25 years. Data on the clinical effectiveness of laparoscopic and open surgery for colorectal cancer were obtained from a systematic review of the literature.
