Cost and cost-effectiveness of cardiac surgery in elderly patients
چکیده انگلیسی

ObjectiveCost-effectiveness of heart surgery for elderly patients is still poorly defined. We evaluated outcome, quality of life (QoL), cost, and cost-effectiveness of octogenarians undergoing cardiac surgery.MethodsOne thousand six hundred forty octogenarians undergoing various cardiac surgical procedures were prospectively studied between January 1998 and January 2009 and compared with similar patients aged 70 to 79 years. Several questionnaires were used to assess QoL. Six hundred age- and sex- matched healthy octogenarians and three hundred forty patients older than 80 years with medically treated valvular or coronary artery disease were healthy and unoperated control groups, respectively. In-hospital costs were obtained from the hospital's financial accounting department and cost-effectiveness was estimated and expressed as cost/QoL-adjusted life year (QALY) and cost-effectiveness ratio.ResultsSignificant improvements occurred in elderly patients in Role Physical (P < .001), Bodily Pain (P < .001), General Health (P = .004), Social Functioning (P < .001), and Role Emotional (P < .001), whereas Physical Functioning, Vitality, and Mental Health did not change (difference not signficant). Total direct costs were $5293 higher in the octogenarian group. Cost-effectiveness was $1391/QALY for elderly surgical patients, $516/QALY for younger cardiac surgical patients (P < .001 vs elderly), $897/QALY for untreated control group, and $641/QALY for healthy control group (P < .001 vs elderly surgical patients). The cost-effectiveness ratio for octogenarians was $94,426.ConclusionsOur findings confirm that cardiac surgery in elderly patients remains controversial from a cost-effectiveness standpoint, making econometric analysis an important component for any future evaluation of novel cardiovascular therapies. Our findings need to be confirmed by additional multicenter studies.
