Cost utility of the multichannel cochlear implants in 258 profoundly deaf individuals.

Cost utility analysis is a method of cost-effectiveness analysis which provides results in terms of cost per quality-adjusted life-year (QALY). Cost utility for the multichannel cochlear implant was calculated using Ontario Health Utilities Index data from 229 Nucleus 22-channel implant users and 32 cochlear implant candidates awaiting surgery. The health utility of the implanted group was greater than that of the candidate group by 0.

Cost effectiveness of the multichannel cochlear implant.

Although most third-party payors presently fund cochlear implantation, some do not, and many cite the current lack of cost-effectiveness data as a major concern. Cost-utility analysis is a widely used method of medical technology assessment that permits cost-effectiveness comparisons between medical interventions by determining the cost per quality-adjusted life-year (QALY) they provide. The cost per QALY for the cochlear implant was determined using clinical cost data and a health-utility outcome model based on the established communication gains attained with the device.

Rural hospital-based alcohol and chemical abuse services: availability and adoption, 1983-1988.

Data from a 1983-88 retrospective panel study of 797 rural (non-Metropolitan Statistical Area) U.S. hospitals revealed that less than one in five (18.

Assessment of cervical cancer screening and follow-up programs.

There is essentially no debate about the benefits of cervical cancer screening. The current debate centers around periodicity, the appropriate interval for repeated testing, and the age at which screening should be discontinued. As the frequency of screening is increased within a defined population, there is a gain in survival (life-years) depending upon the risk status of the population segment screened.
