Cost calculator for mass vaccination response to a US college campus outbreak of serogroup B meningococcal disease.

Serogroup B (MenB) is the leading cause of meningococcal disease among 16- to 23-year-olds in the United States and has been responsible for all 10 college outbreaks between 2011 and 2017. Outbreak-associated costs levy a substantial and unforeseen burden on colleges/universities and surrounding communities, in part because they involve collaboration with local and state health departments to develop points-of-dispensing (PODs) outbreak response plans and rapid mass vaccination of a large at-risk student population. The MenB outbreak at Providence College in 2015 was used as a case study to develop an Excel-based Meningococcal Outbreak Cost Calculator that uses target populations for mass vaccination to estimate the costs and resources associated with a meningococcal disease outbreak response.

The development of a decision analytic model of changes in mean deviation in people with glaucoma: the COA model.

Purpose: To create and validate a statistical model predicting progression of primary open-angle glaucoma (POAG) assessed by loss of visual field as measured in mean deviation (MD) using 3 landmark studies of glaucoma progression and treatment.

Design: A Markov decision analytic model using patient level data described longitudinal MD changes over 7 years.

Participants: Patient-level data from the Collaborative Initial Glaucoma Treatment Study (n = 607), the Ocular Hypertension Treatment Study (OHTS; n = 148; only those who developed POAG in the first 5 years of OHTS) and Advanced Glaucoma Intervention Study (n = 591), the COA model.

Incidence of new coding for dry eye and ocular infection in open-angle glaucoma and ocular hypertension patients treated with prostaglandin analogs: retrospective analysis of three medical/pharmacy claims databases.

Background: To investigate the clinical relevance of two different preservative formulations, we compared 1-year incidence rates of additional coding of dry eye, ocular infection, or ocular surface disease (either dry eye or ocular infection) in open-angle glaucoma and ocular hypertension patients newly treated with latanoprost with benzalkonium chloride (BAK) or with travoprost-Z with SofZia®.

Methods: This was a retrospective study of three U.S.

A multicenter, retrospective chart review study comparing index therapy change rates in open-angle glaucoma or ocular hypertension patients newly treated with latanoprost or travoprost-Z monotherapy.

Background: Because latanoprost and the original formulation of travoprost that included benzalkonium chloride (BAK) have been shown to be similar with regard to tolerability, we compared initial topical intraocular pressure (IOP)-lowering medication change rates in patients newly treated with latanoprost or travoprost-Z monotherapy.

Methods: At 14 clinical practice sites, medical records were abstracted for patients with a diagnosis of open-angle glaucoma or ocular hypertension and who were ≥40 years of age, had a baseline and at least one follow-up visit, and had no prior history of ocular prostaglandin use. Data regarding demographics, ocular/systemic medical histories, clinical variables, therapy initiations and reasons for changes, adverse events, and resource utilization were recorded from randomly chosen eligible charts.

Effectiveness of ophthalmic solution preservatives: a comparison of latanoprost with 0.02% benzalkonium chloride and travoprost with the sofZia preservative system.

Background: Although in vitro and in vivo laboratory studies have suggested that benzalkonium chloride (BAK) in topical ophthalmic solutions may be detrimental to corneal epithelial cells, multiple short- and long-term clinical studies have provided evidence supporting the safety of BAK. Despite the conflicting evidence, BAK is the most commonly used preservative in ophthalmic products largely due to its proven antimicrobial efficacy. This study was designed to characterize the antimicrobial performance of two commonly used topical ocular hypotensive agents that employ different preservative systems: latanoprost 0.

The increased cost of medical services for people diagnosed with primary open-angle glaucoma: a decision analytic approach.

Purpose: Glaucoma accounts for more than 11% of all cases of blindness in the United States, but there have been few studies of economic impact. We examine incremental cost of primary open-angle glaucoma considering both visual and nonvisual medical costs over a lifetime of glaucoma.

Design: A decision analytic approach taking the payor's perspective with microsimulation estimation.

A new measure of patient satisfaction with ocular hypotensive medications: the Treatment Satisfaction Survey for Intraocular Pressure (TSS-IOP).

Purpose: To validate the treatment-specific Treatment Satisfaction Survey for Intraocular Pressure (TSS-IOP).

Methods: Item content was developed by 4 heterogeneous patient focus groups (n = 32). Instrument validation involved 250 patients on ocular hypotensive medications recruited from ophthalmology practices in the Southern USA.
