Systematic screening for diabetic eye disease is cost effectiveBMJ 2000; 320 doi: http://dx.doi.org/10.1136/bmj.320.7250.0/b (Published 17 June 2000) Cite this as: BMJ 2000;320:b
Screening programmes for diabetic eye diseases have become well established in recent years. However, a debate remains over the best way for a screening programme to be implemented. Using data from the Liverpool diabetic eye study James et al show that a systematic screening programme for diabetic eye disease detects more cases of eye disease at a lower cost per case than opportunistic screening (p 1627). This finding remained true for all possible prevalences of the disease and for all sensitivities of opportunistic screening below 95%. Replacing opportunistic with systematic screening would greatly increase the number of cases detected for a small increase in cost.
