Guideline divergence, quantified

Backed by a CMS-recognized, ASCO-approved guideline standard, OncoLens turns the gap between real-world care and evidence-based pathways into evidence your payer, value, and field teams can act on.

A guideline pathway shown as a straight line and real-world care as a line that drifts away from it. The gap between them is divergence, quantified by OncoLens, with points marking an access barrier and clinical discretion.

How OncoLens helps

Backed by OncoLens’ partnership with ClinicalPath from Elsevier, a CMS-recognized evidence pathway and ASCO-approved quality guideline.

Frequently asked questions

What is “guideline divergence” and why does it matter for market access and payer strategy?

Guideline divergence is the measurable gap between how oncology care is actually delivered and what evidence-based pathways recommend. Quantifying it, through OncoLens’s partnership with Elsevier’s ClinicalPath, a CMS-recognized evidence pathway and ASCO-approved quality guideline, turns a qualitative impression into real-world evidence that payer and value teams can cite directly in dossiers and negotiations.

How can this data support payer and value dossiers?

Because ClinicalPath is CMS-recognized and ASCO-approved, guideline concordance data drawn from it carries credibility that generic real-world data sources may lack in payer conversations, giving value and access teams a defensible, third-party-validated evidence base for formulary, coverage, and reimbursement discussions.

Can this data distinguish access barriers from clinical behavior?

Yes. Comparing actual treatment patterns against guideline pathways helps separate cases where care diverges due to structural or coverage barriers from cases reflecting physician discretion, a distinction essential for targeting the right intervention, whether policy engagement or field education.

How does guideline divergence data improve value-based and outcomes-based contracting?

Value-based and outcomes-based contracts depend on knowing where and why care varies from expected pathways, since that variation affects outcomes measurement and risk. Quantified guideline divergence sharpens targeting for these contracts by identifying the patient populations and practice patterns most likely to affect contract performance.

How does this data help field and medical affairs teams?

Field and medical affairs teams need precision on where clinical practice diverges from guidelines to prioritize outreach and scientific engagement effectively. Guideline divergence data adds that precision, helping teams focus deployment where it will have the most impact on aligning care with evidence-based pathways.
