Cost-benefit evaluation of body computed tomography
Health Trends
|July 9, 1987
Summary
Whole body computed tomography (CT) significantly benefited patient care, with 86% of cases showing major clinical contributions. This medical imaging technology demonstrated a cost-benefit ratio of 1:3.07, proving its value.
Area of Science:
- Radiology
- Medical Imaging
- Health Economics
Background:
- Addenbrooke's Hospital received a whole body computed tomography (CT) scanner and radiotherapy planning system as a gift in 1981.
- The gift was conditional on an evaluation of body CT use before future funding decisions.
Purpose of the Study:
- To evaluate the clinical utility and cost-effectiveness of whole body CT scanning.
- To assess the benefits of CT technology in patient management.
Main Methods:
- A detailed assessment of 150 consecutive CT studies was performed.
- An audit of CT usage and an evaluation of running costs were conducted.
- Indirect measurement of benefits, including savings in inpatient bed days and alternative tests, was performed.
Main Results:
- CT findings were considered to have a major contribution to clinical management in 86% of patients.
- CT was more useful than alternative tests in 68% of patients.
- Annual benefits were estimated at £673,385, with a cost-benefit ratio of 1:3.07.
Conclusions:
- Whole body CT scanning provides significant clinical benefits and is a cost-effective diagnostic tool.
- The study supports the value of CT technology in improving patient care and optimizing healthcare resource allocation.
