Unnecessary arterial Doppler examination of the legs. Clinical decision rules may help?
Insights
This study introduces a clinical screening method to reduce unnecessary lower limb arterial Doppler examinations. Implementing this approach improved efficiency by 22% and enhanced service quality through better scheduling.
Area of Science:
- Vascular Medicine
- Health Economics
- Clinical Decision Support
Background:
- Physician prescription habits significantly impact healthcare resource consumption.
- Unnecessary lower limb arterial Doppler examinations represent a target for cost control and quality improvement in vascular diagnostics.
- Current diagnostic pathways may lead to overutilization of non-invasive vascular testing.
Purpose of the Study:
- To develop and evaluate a screening method for lower limb arterial Doppler examinations based on clinical decision rules.
- To reduce the number of non-essential Doppler examinations while maintaining diagnostic accuracy.
- To improve the efficiency and quality of vascular diagnostic services.
Main Methods:
- Designed a screening method using clinical decision rules derived from epidemiological data.
- Utilized patient clinical examination findings and risk factor scores to stratify patients.
- Compared outcomes of screening-guided referrals versus standard referral pathways.
Main Results:
- Successfully identified patients with normal clinical exams and low risk scores as unlikely to have arterial disease.
- Determined that patients with normal exams but very high risk scores require extensive non-invasive evaluation.
- Achieved a 22% reduction in total examination time by safely excluding eligible patients from Doppler studies.
- Implemented a scheduling system prioritizing patients based on clinical severity.
Conclusions:
- A clinical screening examination is effective in safely reducing unnecessary lower limb arterial Doppler examinations.
- This approach enhances healthcare resource allocation and improves the quality of vascular diagnostic services.
- Clinical judgment and risk stratification can optimize the use of non-invasive vascular testing.
Abstract:
Health resources consumption depends mainly on physicians prescription habits. We identified reduction of unnecessary prescribed lower limbs arterial Doppler examinations as an area of potential cost control and quality improvement. We designed therefore a screening method based on clinical decision rules derived from epidemiological considerations: study of our records showed that patients with normal clinical examination and low risk factors score could be considered free from arterial disease by clinical grounds only, and that patients with normal clinical examination and very high risk score needed an extensive noninvasive evaluation. By offering a screening clinical examination (needing a working time shorter than a Doppler examination) with short waiting lists, we were able to safely exclude many normal patients from extensive Doppler examination, improving effectiveness by reducing total examination time by 22% and service quality by a Doppler examinations scheduling based on clinical severity judgement.
