Purpose: To determine the effect of a glaucoma team care model on resource utilization and efficiency in glaucoma management.
Methods: Retrospective cohort study of 358 patients diagnosed and treated for glaucoma. Analysis included number of patient visits, diagnostic tests, and glaucoma procedures performed before (2005-2007) and after (2008-2010) implementation of a team care model in 2008. Patients not involved in the model served as controls.
Results: Number of patient visits did not change significantly after model implementation (p > .05). Diagnostic tests significantly increased in comprehensive ophthalmologist and glaucoma subspecialist groups 25 months after diagnosis (p = .03 and p = .001). Procedures increased for glaucoma subspecialists but was not statistically significant (p = .06). Optometrists used billing codes with significantly lower reimbursement than other providers (p < .001).
Conclusions: Team care model had neutral effect on patient visits and increased testing. Continued evaluation of this model is required to determine its effect on disease progression and outcomes.
