Evaluation of compliance with the EGS guidelines in Spain, using Achievable Benchmarks of Care (ABC®) methodology: the IMCA Study.
OBJECTIVE
To evaluate compliance with diagnostic and therapeutic recommendations of the European Glaucoma Society (EGS) for the management of glaucoma in Spain, as determined using the Achievable Benchmarks of Care approach.


METHODS
A panel of 3 experts extracted quality and process-of-care indicators from the EGS guidelines. Investigators from all over the country, representative of Spanish ophthalmologists, were invited to participate in the study, completing a questionnaire on quality indicators (pertaining to the center) and process-of-care indicators (pertaining to all patients) for the first, diagnostic visit (retrospective) and the study visit.


RESULTS
A total of 495 Spanish ophthalmologists included 5,060 patients with glaucoma or intraocular hypertension. The treatment was initiated with monotherapy in 88.5% of the patients. Overall, the percentage compliance with diagnostic examinations was 84.6% for intraocular pressure measurement, 96.3% for optic nerve head evaluation, 76.6% for visual field evaluation, 29.5% for central corneal thickness evaluation, and 49.3% at the study visit. The benchmark performance was close to 100% for most examinations. Only 32.8% of the centres had a written protocol for the management of the patients with glaucoma, and in these centers the recommendations of the EGS were followed in a higher proportion (p<0.0001) than in the rest.


CONCLUSIONS
The use of local protocols for the management of glaucoma seems to enhance compliance. Benchmark performance was close to 100% in most indicators, suggesting that EGS recommendations are attainable in Spain. The overall performance suggests that certain diagnostic procedures are, in practice, not as widely used as recommended.
