[Cost-benefit analysis of electric stimulation of the spinal cord in the treatment of angina pectoris]. / Cost-utility analyse af elektrisk rygmarvsstimulation til behandling af angina pectoris.

Since August 1988, in Odense Hospital, electric spinal cord stimulation (SCS) has been employed for the treatment of pain in patients with confirmed ischaemic heart disease who suffer from incapacitating angina pectoris despite maximal medical/surgical treatment. The object of the present investigation was to assess not only the social economic consequences of SCS treatment (cost-utility analysis) but also altered quality of life in SCS patients (perception of pain, mobility, function in daily life and physical activity). Sixteen consecutive SCS patients all of whom were resident in the County of Funen and who were submitted to implantation of an SCS system during the period August 1988 to December 1989, participated in this investigation. The results are based on data from the year prior to SCS implantation compared with the subsequent time with SCS treatment. Saving was found at hospital level (reduction in number of admissions) og 40,200 Danish crowns/annum/patient (approximately IJ 3,000) (1989 prices), and for non-hospital related expenses a corresponding saving of 16,289 Danish crowns/annum/patient (approximately IJ 1,600) was found mainly on account of reduction in the amount of home nursing required. The total saving was found to constitute 56,489 Danish crowns/annum/patient (approximately IJ 5,600). In addition, improvements were registered in all respects which constituted assessment of the quality of life of the patients.
