State of the Art Is Not a Literature Dump
You have sixty pages of literature references in your SOTA section. Every relevant study, every guideline, every competitor publication. Reviewers should be impressed. Instead, they write a deficiency asking you to demonstrate understanding of the clinical context. What went wrong?
In This Article
The State of the Art section is one of the most misunderstood parts of clinical evaluation. Manufacturers treat it as a literature collection exercise. Find everything published, cite it all, demonstrate thoroughness. But thoroughness without synthesis is noise. And noise does not pass regulatory review.
MDCG 2020-6 makes the purpose clear: SOTA establishes the clinical context against which your device will be evaluated. It defines current accepted practice, identifies performance benchmarks, and reveals gaps your device might address. This is not about showing you read everything. It is about showing you understand where your device fits.
What Reviewers Actually Need to See
When a Notified Body reviewer opens your SOTA section, they are looking for answers to specific questions. What is the current standard of care for this clinical condition? What alternatives exist and how do they perform? What performance benchmarks should this device meet or exceed? What gaps or unmet needs exist that your device addresses?
A literature dump answers none of these questions. It presents raw material and forces the reviewer to do your synthesis work. This is not their job. And they will not do it. They will send the document back.
SOTA is an argument, not a bibliography. You are building the case for why your device makes clinical sense in the current treatment landscape.
The Real Purpose of SOTA
Your SOTA section serves multiple interconnected purposes. It establishes the clinical need your device addresses. It identifies the comparators against which your device will be judged. It defines the performance thresholds you need to meet. It reveals the evidence gaps that inform your PMCF strategy.
Each of these purposes requires analysis, not just citation. You need to synthesize multiple sources into a coherent picture of current practice. You need to identify patterns across studies. You need to draw conclusions that inform the rest of your clinical evaluation.

Common SOTA Failures
The most common failure is treating SOTA as comprehensive literature review. Every paper mentioned, none analyzed. Long lists of studies with no explanation of what they collectively tell us about the clinical context.
Another common failure is outdated content. SOTA must reflect current practice. A section written three years ago that has not been updated despite new guidelines, new competitors, or new clinical evidence is immediately suspect.
A third failure is disconnection from the device. SOTA sections that could apply to any device in the category, with no specific connection to your device’s features, claims, or intended use. Generic does not demonstrate understanding.
Write your SOTA as if explaining to a clinical expert why your device makes sense. What would they need to know about current practice to understand your device’s value proposition?
Structure That Works
An effective SOTA section follows a logical structure. Start with the clinical condition and patient population. Move to current diagnostic or treatment approaches. Present the performance of existing solutions with specific metrics. Identify limitations and unmet needs. Connect these findings to your device’s intended purpose.
This structure creates a narrative. The reader understands the problem, sees how it is currently addressed, recognizes the limitations, and is prepared to evaluate your device as a potential solution.
Quality Over Quantity
A well-synthesized SOTA section might be shorter than a comprehensive literature dump. This is not a problem. What matters is the quality of analysis, not the number of citations. Ten well-chosen, well-analyzed sources that build a clear picture of current practice are more valuable than a hundred citations presented without synthesis.
The goal is demonstrating that you understand the clinical context deeply enough to position your device appropriately. This requires thought, not just searching.
In the next post, we will walk through a five-step method for converting your literature research into a SOTA summary that reviewers actually want to read.

Frequently Asked Questions
How long should a SOTA section be?
Length matters less than quality. A well-synthesized SOTA of 5-10 pages that demonstrates clear understanding of clinical context is better than 50 pages of citations without analysis. Focus on answering the key questions: current standard of care, performance benchmarks, and unmet needs.
How often should SOTA be updated?
SOTA must reflect current practice. Update when new clinical guidelines are published, significant studies emerge, new competitors enter the market, or at minimum during each CER update cycle. An outdated SOTA undermines your entire clinical evaluation.
What sources should SOTA include?
Clinical guidelines, pivotal studies, systematic reviews, competitor data, registry data, and expert consensus documents. The key is selecting sources that inform understanding of current practice, not comprehensiveness for its own sake.
