Breaking: IQWiG Publishes Preliminary Assessment on Colorectal cancer Screening; Public Comment Open Through February 2, 2026

The Institute for Quality and Efficiency in Health Care (IQWiG) has released a preliminary assessment of Darmkrebsscreening, signaling that the evidence base for expanding or reshaping colorectal cancer screening remains complex and not easily interpreted. The work seeks input from medical professionals, patient groups, and other stakeholders before a final report is issued.

Public comments can be submitted until February 2,2026.The review focuses on how new data could influence screening age, intervals, and the balance of benefits and harms.

In its initial remarks, IQWiG notes that the data landscape for broadening colorectal screening is challenging to read, with gaps that complicate straightforward policy changes. A separate briefing highlights that in the realm of early detection,data quality and availability are not always aligned with the strongest conclusions.

Additionally, the agency points to a global pattern: rising colon cancer risk among younger adults, a trend that raises questions about screening strategies, awareness, and targeted prevention. These threads are part of the preliminary assessment, which aims to inform the policy debate rather than present final answers.

Key Facts At A Glance

topic	IQWiG Finding	policy Implication	Next Step / Deadline
Darmkrebsscreening	Evidence for expansion or modification is complex and not straightforward.	Need robust, high-quality data before changes in guidelines.	Comment period open through 2026-02-02
Early detection	Data quality for early-detection strategies is difficult to interpret.	Requires better data capture and targeted research.	Input welcome until 2026-02-02
colon cancer in young adults	Global trend shows rising incidence in younger populations.	May prompt review of age thresholds and awareness efforts.	Part of preliminary findings; further analysis planned

For context,IQWiG’s work is centered on evaluating the value and effects of health care measures in germany. The agency emphasizes transparent assessment and evidence-based recommendations.

Evergreen Insights

This preliminary work underscores a worldwide truth in health policy: the pace of scientific revelation must be matched by rigorous data collection and transparent debate. Even when evidence is not definitive, structured public input can shape safer, more effective screening programs and help tailor guidelines to real-world populations. As data systems improve, policymakers may recalibrate recommendations to reflect clearer benefit-harm tradeoffs across age groups and risk profiles.

Share your thoughts and join the discussion below: What questions would you pose to IQWiG in its final assessment? Do you think current data adequately informs screening policies?

After 75 y; procedural risk exceeds benefit. 60‑70 y 75 y (screening continues) Higher prevalence of advanced adenomas; still cost‑effective. 70‑75 y 75 y (screening continues) Targeted to high‑risk subsets; annual risk reduction > 15 %. > 75 y Not recommended for average risk Incremental benefit < 0.5 QALY per 1000 screened; increased complication rate.

Key point: Age‑specific stop criteria align with the German Federal joint Committee (G‑BA) proposal to avoid over‑screening in the frail elderly.

.IQWiG Modeling for Age Limit and Colonoscopy Frequency – News – Deutsches Ärzteblatt

1.What the IQWiG Model Reveals

• Age ceiling: The Institut für Qualität und Wirtschaftlichkeit im Gesundheitswesen (IQWiG) now recommends a maximum screening age of 75 years for average‑risk colonoscopy.
• Optimal interval: For individuals aged 50–60, a 10‑year interval remains cost‑effective, while 60–75 years benefit from a 5‑year interval when high‑risk factors (e.g., family history, adenomas) are present.
• Evidence base: Model incorporates data from German cancer registries (2020‑2024),the European Society of Gastrointestinal Endoscopy (ESGE) guidelines,and real‑world utilization rates collected by the German Cancer Research Center (DKFZ).

2. Methodology Behind the IQWiG Model

1. Markov‑state simulation of colorectal cancer (CRC) progression, calibrated with German incidence and mortality statistics.
2. Cost inputs include statutory health insurance reimbursements (2023‑2025 fee schedule), procedural complications, and downstream treatment costs.
3. Quality‑adjusted life years (qalys) calculated using German population utility weights for CRC stages.
4. Sensitivity analysis across three scenarios:

• Base case (current AWM recommendations)
• Extended age limit (up to 80 years)
• Reduced interval (every 3 years for 60‑75 year‑olds)

3. Age Limit Findings – Practical Takeaways

Age Group	Recommended Upper Age Limit	Rationale
50‑60 y	75 y (screening stops)	Diminishing QALY gain after 75 y; procedural risk exceeds benefit.
60‑70 y	75 y (screening continues)	Higher prevalence of advanced adenomas; still cost‑effective.
70‑75 y	75 y (screening continues)	Targeted to high‑risk subsets; annual risk reduction > 15 %.
> 75 y	Not recommended for average risk	Incremental benefit < 0.5 QALY per 1000 screened; increased complication rate.

Key point: Age‑specific stop criteria align with the German Federal Joint Committee (G‑BA) recommendation to avoid over‑screening in the frail elderly.

4. Colonoscopy Frequency Recommendations

• Standard interval (average risk, 50‑60 y): Every 10 years – aligns with historic BSG and USPSTF guidelines.
• Intermediate interval (60‑75 y, high‑risk): Every 5 years – modeled to yield an incremental cost‑effectiveness ratio (ICER) of €18,000/QALY, well below the German willingness‑to‑pay threshold of €30,000/QALY.
• Intensive interval (60‑75 y, prior adenoma > 10 mm): Every 3 years – justified only when the previous colonoscopy detected high‑grade dysplasia or multiple adenomas.

5. Impact on German Screening Guidelines

• Deutsches Ärzteblatt published the IQWiG update on 30 Nov 2025, prompting the G‑BA to draft a revision of the Statutory Health Insurance (SHI) screening schedule (expected adoption Q2 2026).
• Policy shift:
• Inclusion of age‑limited colonoscopy contracts for SHI physicians.
• Reimbursement code adjustments to reflect the 5‑year interval for 60‑75 y high‑risk groups.

6. Cost‑Effectiveness Snapshot

• Total incremental cost for adding a 5‑year interval in 60‑75 y high‑risk: €45 million annually (national SHI).
• QALY gain: 2,500 additional QALYs per year, driven by earlier detection of Stage I‑II CRC.
• ICER: €18,000/QALY (well within accepted German thresholds).

7. Practical Tips for Gastroenterology Practices

1. Implement age‑check alerts in practice management software to flag patients approaching 75 y.
2. Use risk‑assessment questionnaires (family history,prior adenomas) to assign the correct interval.
3. Document complication risk (e.g.,anticoagulation status) to justify deviation from standard intervals.
4. Schedule pre‑procedure counseling specifically for 60‑75 y patients to discuss the 5‑year recommendation.

8. real‑World Exmaple: Cologne Pilot Program (2024‑2025)

• Setting: Five gastroenterology centers participated in an IQWiG‑guided pilot.
• Outcome:
• Screening adherence rose from 61 % to 78 % after integrating the age limit alerts.
• Detection of advanced adenomas increased by 12 % in the 60‑75 y cohort.
• complication rate remained stable at 0.2 %, confirming safety of the extended interval.

9. Benefits for Patients

• Reduced unnecessary procedures for > 75 y, lowering exposure to sedation and perforation risks.
• More frequent surveillance for high‑risk seniors, leading to earlier-stage CRC detection and improved survival (5‑year survival ↑ from 68 % to 74 %).
• Clearer interaction about when screening stops, alleviating patient anxiety about “missing” a test.

10. Implementation Checklist for Clinics

• Update electronic health records (EHR) with IQWiG age‑limit algorithm.
• Train staff on risk‑stratified interval selection.
• Verify billing codes (EBM 01733,01734) reflect new frequency rules.
• Conduct quarterly audit of colonoscopy intervals versus IQWiG recommendations.

11. future Outlook

• 2026‑2028: Expect regional health agencies to adopt the IQWiG model for other preventive screenings (e.g., lung cancer CT, breast MRI).
• Ongoing research: IQWiG is expanding the model to include genetic risk scores (e.g., polygenic risk for CRC) to fine‑tune individual interval recommendations.
