Rapid identification of viruses has important implications for medical healthcare. Current methods for identification and quantification of particular virus are time consuming and often expensive. Therefore, demand for sensitive and accurate viral biosensors with rapid detection systems is increasing. A hand held biosensing device would give fast, reliable results for identifying and quantitating the number of virus particles in a sample. Techniques currently being applied to achieve this aim include electrochemical biosensors, based on amperometric, potentiometric and impedance measurement, optical biosensors using surface plasmon resonance (SPR), optical fibers and piezoelectric biosensors based on microcantilevers. Future research also looks to the use of nanoparticles and novel nanomaterials as alternate recognition surfaces for use in a variety of sensor formats.

Review of the medical necessity of hospital or other health facility admissions, upon or within a short time following an admission, and periodic review of services provided during the course of treatment.
The ability to detect sharp boundaries (stimuli) and to detect slight changes in luminance at regions without distinct contours. Psychophysical measurements of this visual function are used to evaluate visual acuity and to detect eye disease.
Formal programs for assessing drug prescription against some standard. Drug utilization review may consider clinical appropriateness, cost effectiveness, and, in some cases, outcomes. Review is usually retrospective, but some analysis may be done before drugs are dispensed (as in computer systems which advise physicians when prescriptions are entered). Drug utilization review is mandated for Medicaid programs beginning in 1993.
