COST SAVINGS WITH NONTHORACOTOMY IMPLANTABLE CARDIOVERTER-DEFIBRILLATORS

We analyzed hospital and physician charges for 99 consecutive patients who underwent implantable cardioverter-defibrillator (ICD) implantati on at our institution. Eighteen patients received an epicardial lead s ystem and 81 were scheduled to receive a nonthoracotomy lead system, t he generator being implanted either abdominally (n=62) or pectorally ( n=19). The epicardial group had a significantly longer convalescent st ay (11.6+/-2.5 days; mean+/-SEM) than the abdominal nonthoracotomy gro up, analyzed by intention to treat (4.6+/-0.5 days) or by treatment re ceived (3.8+/-0.2 days; p <0.0001). Postoperative stay for the pectora l group was shorter still (2.9+/-0.4 days; p <0.033). Total charges fo r the epicardial group were $99,081+/-$25,094, significantly higher th an those for any of the nonthoracotomy groups (p <0.017). Total charge s for the pectoral group were $44,128+/-$2,465, significantly less tha n those for the abdominal nonthoracotomy group, analyzed by intention to treat ($59,961+/-$1,369; p <0.05) or by treatment received ($56,679 +/-$635; p <0.05). Cost reductions in the nonthoracotomy groups were p rimarily due to decreased in-hospital convalescence period, lower surg eon and anesthesiologist fees, and lower procedure-day hospital charge s in the pectoral group. The use of ICDs with nonthoracotomy leads can result in significantly shorter in-hospital convalescence and a reduc tion in total implant-related charges of 40% to 55%. The use of pector ally implanted ICDs results in further reduction in hospital stay and further cost reduction of 22% to 26%. The trend coward shorter convale scent stay without postimplant testing is likely to reduce further the overall costs of ICD implantation. (C) 1996 by Excerpta Medica, Inc.
