Importation (used interchangeably with re-importation by many policymakers) typically occurs on an individual level when Americans import drugs for personal use by either filling their prescriptions in Canada or Mexico or through mail-order/internet pharmacies. ‘Drug importation’ is the practice of importing prescription drugs that were manufactured, either domestically or abroad, with the intent for sale in another country. In this context, much attention has been devoted to large-scale importation at the state or national level. Consumers and policymakers alike have highlighted the significant differences in cost between the U.S. The financial burden of these therapies has yielded renewed interest in alternative methods to reign in cost.
Patients are potentially thus confronted with high out-of-pocket expenses for years on end.Ī study by the Kaiser Family Foundation showed median annual out-of-pocket expenses of Medicare beneficiaries in 2019 for the following common drugs used in various hematologic malignancies: venetoclax $8,712, imatinib $8,983, acalabrutinib $10,175, midostaurin $11,830, and lenalidomide $14,461. However, many of these agents are novel and not yet subject to generic or biosimilar price pressure. Considerable therapeutic advances in the treatment of hematologic neoplasms have resulted in marked improvements in overall survival and resulted in some of these conditions being treated like chronic diseases. In cancer, where pharmaceutical spending represents upwards of 20% of total spending, the issue is especially salient. with prescription sales in 2016 exceeding $448 billion. Prescription drugs account for 10% of overall health spending in the U.S. A solution to avoid underestimating the exposure without increasing too much the calculation time may be to only account for preponderant noise sources beyond a given distance.As part of the larger discourse on rising healthcare expenditures in the U.S., the affordability of prescription drugs continues to occupy a significant position in health policy debate with the majority of Americans believing that lowering their cost is a top health care priority. Third, increasing the search radius can quickly lead to an impractical calculation time. Second, the impact of a change in search radius is very dependent of the presence of preponderant noise sources.

First, despite a search radius often fixed to 1000 m by noise prediction software users, going up to 2000 m shows significant increase in population’s exposure. The result of this investigation highlights several points.
To understand the influence of this parameter on the evaluation of population’s exposure, the search radius has been successively fixed to three different values (500 m, 1000 m and 2000 m) in four different geographical situations (village, industrial, suburban and inner city). The search radius is the threshold distance from which noise sources are not considered anymore in the exposure assessment. This paper investigates the impact of the search radius, a parameter used in emission and propagation models, on noise exposure results. Engineering software products allow for quantifying environmental noise and a population's exposure to road traffic noise which can then be linked to human health damage.
