Pacemaker implantation significantly improves health values in elderly patients, enhancing quality of life regardless of pacing mode. This demonstrates the cost-effectiveness of pacemakers for improving patient well-being.

Area of Science:

  • Gerontology
  • Cardiology
  • Health Economics

Background:

  • Health value quantifies preference for quality and quantity of life.
  • It's used in cost-effectiveness analysis to calculate quality-adjusted life years.
  • This study focuses on health values in elderly patients undergoing pacemaker implantation.

Purpose of the Study:

  • To assess changes in health values among elderly patients before and after pacemaker implantation.
  • To evaluate the impact of different pacemaker modes on health values.

Main Methods:

  • Prospective study of 398 elderly patients from the Pacemaker Selection in the Elderly trial.
  • Patients randomized to VVIR or DDDR pacing modes.
  • Health values measured using the time tradeoff method pre-implantation and at 3, 9, and 18 months post-implantation.

Main Results:

  • Baseline health value was 0.76 ± 0.06, with no significant difference based on implant diagnosis.
  • Overall improvement in health values by 3 months post-implantation was 0.165 (P=.0001), independent of pacing mode.
  • Patients with lower functional class (III/IV) showed a 23% improvement in health values, compared to 12% in higher classes (I/II).

Conclusions:

  • Permanent pacemaker implantation improves health values and health status in elderly patients.
  • These health value data can inform cost-effectiveness analyses of pacing therapies.
  • Pacemaker implantation is a valuable intervention for enhancing the quality of life in elderly cardiac patients.
