A Comparison Of Clinical Trial And Model-Based Cost Estimates In Glaucoma – The Case Of Repeat Laser Trabeculoplasty In Ontario, Omar Akhtar

Electronic Thesis and Dissertation Repository

Background and objective: For cost-effectiveness analyses (CEA) of glaucoma interventions to be of use they require valid and accurate cost and effectiveness data. Costs remain understudied relative to effectiveness. The impact of cost estimation methods on resultant estimates is unknown in glaucoma. Direct measurement of costs is labour-intensive and expensive. Decision-analytic modelling of costs using literature sources, expert opinion, institutional experience and assumptions provides a quicker, less laborious alternative to empirical costing. A lack of long-term effectiveness data in chronic diseases like glaucoma means that modelling is widespread and inevitable, both for CEAs and budget impact projections. The same problem …

In Adult Patients With Diabetic Macular Edema Are Intravetrial Bevacizumab Injections More Effective Than Laser Therapy At Improving Best-Corrected Visual Acuity?, Heather Bladek

PCOM Physician Assistant Studies Student Scholarship

OBJECTIVE: The objective of this selective EBM review is to determine whether or not in adult patients with diabetic macular edema intravetrial bevacizumab injections are more effective than laser therapy at improving best-corrected visual acuity.

STUDY DESIGN: Review of three English language non-blinded randomized control trials from 2010 and 2012.

DATA SOURCES: Non-blinded randomized control trials comparing intravetrial bevacizumab injections to macular laser therapy found using Pubmed and EBSCOhost web databases. All articles were published in peer-reviewed journals.

OUTCOMES MEASURED: The primary outcome of best-corrected visual acuity (BCVA) was measured using the Early Treatment of Diabetic …
