Digital containment: Revisiting containment strategy in the digital age

Utilization management as a cost-containment strategy

Utilization management (UM) is now an integral part of most public and private health plans. Hospital review, until recently the primary focus of UM, is associated with a reduction in bed days and rate of hospital cost increases. These reductions appear to have had limited impact on aggregate health care costs because of increases in unmanaged services. In the future, with electronic connectivi...

Rekeyed Digital Signature Schemes: Damage-containment in the face of key exposure

Motivated by the problem of delegating signing keys to vulnerable mobile devices, we define rekeyed digital signature schemes. We provide an adversary model and a strong notion of security for such schemes, and show that the classic self-certification paradigm, properly implemented, provably meets this notion of security. We then suggest altnerative solutions, based on identification schemes, a...

Digital ischaemia in the digital age

After the accidental injection of epinephrine into a digit, various techniques to try and reverse the ensuing ischaemia were unsuccessful. To identify a further treatment strategy and as members of the admitting team were unfamiliar with digital injection of epinephrine a Google search was performed. Previous cases were described and separate sources indicated appropriate management protocols u...

Cost Containment in Europe

Health care cost containment is not in itself a sensible policy objective, because any assessment of the appropriateness of health care expenditure in aggregate, as of that on specific programs, requires a balancing of costs and benefits at the margin. International data on expenditures can, however, provide indications of the likely impact on costs and expenditures of structural features of he...
