Providing correlative studies for IAC accreditation is an important step in the process, more importantly it demonstrates a commitment to quality and is a critical component of a good quality assurance program. For many, IAC accreditation is considered the “gold standard” for quality in vascular testing. IAC requires labs to prove that their vascular testing meets the national quality standards and uses correlative study data as proof that the vascular ultrasound exams performed are accurate. This data should include a comparison of the results obtained from non-invasive testing and another acceptable diagnostic test, such as MRA or CTA.
While IAC looks at the accuracy of the studies, a comprehensive quality assurance program should include regular audits for sensitivity, specificity, positive predictive value, and negative predictive value of the non-invasive testing. The correlative studies for IAC Accreditation should be maintained and done at least twice per year.
There are differences in facilities with regard to how the correlative studies are performed and interpreted, NAVIX looks for these differences and helps labs implement a comprehensive quality assurance program for continuous improvement. The critical data for this type of analysis typically includes:
- Clinical Correlation
- Quality Review Audit results
- Surgical Outcomes
- Venous Ablation Outcomes, if applicable
- Pre-operative dialysis access site evaluations compared to successful use of
Noninvasive vascular labs that consistently perform at a high level provide the clinical information that is required by the vascular specialist to effectively diagnose and treat disease.
The IAC provides accreditation programs for vascular testing, echocardiography, nuclear/PET, MRI, diagnostic CT, dental CT, carotid stenting, vein treatment and management, cardiac electrophysiology and cardiovascular catheterization. The IAC programs for accreditation are dedicated to ensuring quality patient care and promoting health care and all support one common mission.
You should know that the IAC periodically reviews and changes the standards for accreditation. It is also important to note that there audits of accredited labs are typically done within the three-year accreditation cycle and accredited facilities should maintain their quality assurance programs to ensure they do not lose their IAC accreditation.
