Similarly, the second part of the model divorced persons than among married persons, and was used to predict expenditures, conditional upon 298 299 Urologic Diseases in America Methods this inconsistency might be identifed for further review. This allowed for an evaluation of whether any unusual rates were reported for a particular year or service. To this end, a comprehensive literature review was performed using the relevant disease search terms. Rates generated from the datasets were compared with published estimates, and clinical experts adjucated whether discrepancies signaled analysis errors. Also, confdence interval calculations were reviewed to ensure that they were within the appropriate range for all rates reported. For the next level of verifcation, a mean-annual- payment summary table was produced to compare payments across years and services. Again, any payments that appeared out of range were fagged for further evaluation. In many cases, a small sample size explained a wide variation in reported payments Finally, summary base population tables were generated for all conditions and years. These tables were examined to ensure that the sum of subpopulations equaled the base population for any given year, and that the correct base populations were used for each year. This systematic approach to reviewing data quality successfully uncovered issues that were later remedied at all levels of evaluation.

Often, such surgery is Newer glaucoma medications include augmented by the use of antibrotic agents per- latanoprost, dorzolamide and brimonidine. These agents inhibit broblast activity, produces its intraocular pressure-lowering and increase the success rate of surgery, but effect through increased uveoscleral outow. Prostaglandin analogues are licensed as lower intraocular pressure by ablating part of rst-line medication for glaucoma and have the ciliary body (this area produces the aqueous superseded beta-blockers in effectiveness and humour). Other prostaglandin-related medi- sible, and although easier to perform than cations include bimatoprost (Lumigan) and conventional glaucoma surgery, is generally travoprost (Travatan), which have similar reserved for patients with advanced uncon- mechanisms of action to latanoprost. Dorzolamide (Trusopt) and brinzolamide (Azopt) are topically administered carbonic anhydrase inhibitors. Their pressure-lowering effect is inferior to that of timolol, but they are useful adjunctive medications. Brimonidine (Alphagan) is an a2-adrenergic agonist, which decreases aqueous production and also increases the uveoscleral outow. If the intraocular pressure remains uncon- trolled by safe medical treatment and there is evidence of continued loss of visual eld, surgi- cal treatment is indicated.
