Glaucoma Agreement in New Zealand (GAINZ)

Le résumé fourni par la source

CLINICAL RELEVANCE: With an ageing population, ophthalmologists are becoming burdened with glaucoma management, and patient care can be delayed. Therefore, the use of optometrists in glaucoma management can help alleviate the burden. BACKGROUND: The ageing population and subsequent rise of glaucoma prevalence are putting a strain on the public health system in New Zealand. Glaucoma collaborative care between optometrists and ophthalmologists has been gaining support with the aim to reduce this burden on ophthalmologists. There has been little investigation of the agreement in care and management of mild-to-moderate severity glaucoma patients by optometrists and ophthalmologists. METHODS: One hundred and three glaucomatous eyes were used in a survey where clinical history and examination, intraocular pressures (IOPs), visual field testing and optical coherence tomography (OCT) imaging were evaluated for glaucoma progression and decision-making regarding subsequent management by four participants. Two participants were glaucoma-credentialled optometrists (Group 1), and the other two were glaucoma specialists (Group 2). RESULTS: With respect to glaucoma progression, Spearman coefficients identified strong agreement between the two groups for IOP, visual fields and overall status and moderate agreement for OCT imaging. A confusion matrix was used to analyse management and found 80% ± 10% agreement between the two groups. Review periods gave an agreement of 55% ± 20% between the two groups. CONCLUSION: There was strong agreement in the assessment of glaucoma progression between the two groups. The 80% level of agreement for subsequent management between the two groups is comparable to other published reports. These results provide some reassurance that a collaborative care system can perform safely and as intended.
