Analysis of a Physician-led, Team-based Care Model for the Treatment of Glaucoma

Purpose: To determine the effect of a protocol for a new physician-led, team-based glaucoma care model implemented in 2008 at Mayo Clinic's campus in Rochester, Minnesota (MCR), to increase conformance with the American Academy of Ophthalmology (AAO) Preferred Practice Pattern guidelines for treatment of primary open-angle glaucoma. Methods: Records of 591 patients with newly diagnosed glaucoma were assessed retrospectively for the completion of 9 AAO Preferred Practice Pattern recommended metrics including measured corneal thickness, intraocular pressure (IOP), cup to disk ratio, visual acuity, recorded IOP target, gonioscopy, fundus photos, ocular coherence tomography, and visual field in the 3 years before and 3 years after protocol implementation. Treatment by the glaucoma care team at MCR was compared with treatment at a community-based general ophthalmology practice and with a group of comprehensive ophthalmologists at MCR without team care, which served as controls. Results: Adherence to AAO recommendations increased for the documentation of target IOP (+24%, 42.6% to 66.7%; P=0.007), gonioscopy (+27%, 66.7% to 93.3%; P≤0.001), fundus photos (+29%, 44.4% to 73.3%; P≤0.001), and ocular coherence tomography (+20%, 48.1% to 68.0%; P=0.02) after protocol initiation. No change in pattern of testing occurred in the control groups without team care during the same time period. Type and severity of glaucoma were similar between MCR and community practice. Conclusions: An increase in compliance with AAO guidelines was found after implementation of our protocol for a physician-led, team-based care model to standardize glaucoma care among providers.
