Anticipating and Assessing Health Care Technology: Health by H. David Banta, Annetine Gelijns (auth.)

By H. David Banta, Annetine Gelijns (auth.)

As famous within the Foreword, this record is one of many volumes as a result of this learn of overall healthiness care expertise. the aim of the learn, as formulated via the STG, used to be to research health care expertise. a part of the duty used to be to boost an 'early caution approach' for overall healthiness care expertise. the first target of the undertaking used to be to boost a listing or description of a few attainable and possible health care applied sciences, in addition to details on their value. in the limits of money and time, this has been performed. even though, given the mammoth variety of attainable health and wellbeing care applied sciences, entire info at the value of every sector couldn't be constructed in any intensity for all expertise. hence, 4 particular applied sciences have been selected and have been prospectively assessed. those destiny applied sciences have been tested in additional intensity, having a look fairly at their overall healthiness and coverage implications. for this reason, the venture was once prolonged to September 1986, and extra applied sciences might be assessed.

This decline is independent of the fall in age-specific incidence and mortality rates. It reflects a rapid resolution of the backlog of candidates for coronary artery bypass surgery, built up during the years that there was limited capacity for this surgery. c: 3 . * Starting from the upper left hand corner, healthy people become symptomatic with ischemic heart disease. They then become patients on medication (and some of those become healthy and move back into the healthy state). Of those people who are symptomatic and on medication, 7 percent a year have a medical examination that includes angiography to directly examine the state of their coronary arteries.

Payment for services based on lasers will need to be developed where appropriate. Laser applications in health care raise many important implications for the future. 37 Appendixes 39 APPENDIX A TECHNICAL BACKGROUND ON LASERS Laser devices employ an energLzLng source or pump, such as highintensity light or electric current, to cause atoms, molecules, or ions in a medium to radiate highly directional light of (almost) a single wavelength, called coherent light (See Figure 7). ) Atoms and molecules exist in nature at low and high energy levels.

Restenosis (closing of the artery) occurs in 25 to 35 percent of ipatients, usually within 6 months of the procedure (3). I Prospects for Laser Treatment of Coronary Artery Disease Many workers have recanalized coronary arteries with lasers in cadavers and in animals (10;34). Choy et al (11) performed the first intra-operative coronary artery recanalizations in living human patients, using an Argon laser coupled to a bare fiber. Others have used a laser in a similar way during heart surgery (41;42).
