The costs of coronary artery surgery to the community
Insights
Coronary artery bypass grafting (CABG) shows low mortality and significant patient benefits, including improved home duties for women and fewer doctor visits. This cardiac surgery also benefits the community by maintaining workforce productivity.
Area of Science:
- Cardiovascular Surgery
- Public Health
- Health Economics
Background:
- Coronary artery bypass grafting (CABG) is a major cardiac surgical procedure.
- Assessing long-term patient and community benefits of CABG is crucial for healthcare policy.
- Previous studies have focused on mortality, with less emphasis on functional and economic outcomes.
Purpose of the Study:
- To evaluate the long-term benefits of coronary artery bypass grafting (CABG) for both patients and the wider community.
- To assess changes in employment status, functional capacity, and healthcare utilization post-CABG.
- To determine the overall impact of CABG on productivity and healthcare costs.
Main Methods:
- A retrospective analysis of 4001 patients who underwent CABG between 1971 and 1982.
- Utilized a fixed-response questionnaire for patient assessment with a 98.8% follow-up rate.
- Compared patient outcomes, including employment shifts and home duties, with general population data.
Main Results:
- Hospital mortality for CABG was low at 1.4%, with a decreasing trend observed over the study period.
- While 548 employed patients ceased work, this was primarily attributed to age, not the surgery.
- Significant improvements were noted in female patients' ability to perform home duties, and 50% of survivors reported fewer doctor visits.
Conclusions:
- Coronary artery bypass grafting (CABG) is associated with low mortality and offers substantial benefits to patients, including improved functional capacity and reduced healthcare utilization.
- The community benefits from CABG through sustained workforce productivity and decreased long-term medical care costs.
- CABG represents a valuable intervention with positive socioeconomic implications beyond immediate clinical outcomes.
Abstract:
The possible benefits obtained both for the community and patients following coronary artery bypass grafting (CABG) have been examined in 4001 patients (mean age 54 years, 14.8% female) who underwent CABG from 1971 to 1982 in the Cardiothoracic Surgical Unit of the Royal Adelaide Hospital. Assessment followed a fixed response format questionnaire sent to all patients with a total follow-up of 98.8%. The hospital mortality was 1.4% for the 10 year period with a fall from 4% in 1973 to 0.9% in 1981. Shifts in employment were assessed in survivors. At follow up, 548 patients who were previously employed had ceased full-time or part-time employment. This decrease in employment was attributed mainly to age. Analysis of retirement curves for the general male population and male patients showed a similar pattern but downward translation of 4% for the pre-operative group. A similar downward shift occurred following surgery. For female patients, performance of home duties improved from 159 patients on full home duties pre-operatively to 292 post-operatively. Visits to the doctor dropped in 50% of surviving patients. CABG has a low mortality. The community benefits by helping to maintain productivity and decreased cost for ongoing medical care.
