Insights
Implementing a cost reduction program for open heart surgery significantly decreased hospital costs and patient waiting times. This initiative improved efficiency without negatively impacting patient outcomes or mortality rates.
Area of Science:
- Healthcare Management
- Surgical Efficiency
- Cost Reduction Strategies
Background:
- Increasing demands on healthcare systems necessitate cost-efficiency measures.
- Surgical waiting lists present a significant challenge in healthcare delivery.
- Optimizing resource allocation is crucial for maintaining service quality.
Purpose of the Study:
- To evaluate the impact of a cost reduction program on surgical waiting lists.
- To assess the feasibility of increasing surgical case volume within existing budgets.
- To determine the effect of cost-saving measures on healthcare service delivery.
Main Methods:
- Retrospective analysis of open heart surgery patients at University of Alberta Hospitals (March 1991 - February 1992).
- Comparison of patient groups before and after implementation of a cost reduction program (September 1, 1991).
- Statistical analysis using Student's t-test and logistic regression to compare outcomes.
Main Results:
- Significant reductions in operating time (4.5 to 4 hours) and total hospital length of stay (19.3 to 13.8 days).
- Decreased costs in operating room, nursing, and radiology, leading to a substantial drop in overall hospital costs ($14,182 to $10,710).
- No significant differences in demographic features, severity indices, mortality, or readmission rates between groups.
Conclusions:
- Cost savings can be achieved through modified practice patterns without compromising patient safety or outcomes.
- Intensive care unit (ICU) and overall hospital length of stay are key determinants of healthcare costs.
- The study demonstrates the effectiveness of targeted cost reduction programs in improving surgical throughput and efficiency.
Objective:
To reduce surgical waiting lists at the University of Alberta Hospitals. A cost reduction program was initiated, allowing more cases to be performed on the same budget. Reducing the cost of delivering health care services has become necessary as demands upon the system increase.
Methods:
Data were retrospectively gathered on patients having open heart surgery at the University of Alberta Hospitals between March 1, 1991 and February 29, 1992. Group 1 were patients operated on before the start of the cost reduction program (September 1, 1991) and group 2 were those operated on after. Student's t test and logistic regression were use to compare population characteristics and to correlate dependent variables.
Results:
Demographic features and severity indices were not different. Operating time decreased from 4.5 +/- 1.5 to 4 +/- 1 h, P < 0.002. Preoperative, intensive care unit (ICU) and postoperative ward length of stay were reduced (P < 0.002). Total length of stay went from 19.3 +/- 22.7 to 13.8 +/- 10.7 days, P < 0.001. Operating room, nursing and x-ray costs decreased, P < 0.002. Hospital costs declined from $14,182 +/- 16,464 to $10,710 +/- 7,332, P < 0.001. Multiple regression showed hospital stay, ICU, operating room time, severity of illness and age to be significant determinants of cost, P < 0.03 for each. Waiting time and number of patients on the waiting list declined significantly as surgical lists increased. Mortality and rate of readmission following discharge were not different between the two groups.
Conclusions:
Substantial cost savings can be made by changing practice patterns, without adverse consequences. ICU and hospital length of stay are the most important cost determinants.
