Why Healthcare Businesses Need Evidence and How to Take the First Step
Many companies understand that evidence is important for healthcare businesses, but struggle with how far to go and where to start. This article organizes the levels of evidence needed at each business phase and how to take the first practical step.
Article Digest
Key Points
- Evidence is not just academic papers — it comes in stages matched to business needs
- Different business phases require different levels of evidence
- The first step is articulating what you want to prove
Conclusion
Evidence in healthcare business does not mean only achieving statistical significance in an RCT. The realistic approach is to build incrementally — literature review, user surveys, observational studies, PoC, then RCT — matched to each business phase. The first step is articulating what you want to prove and choosing a research design that fits your business objective.

Background
Evidence is discussed in healthcare businesses in four main contexts: sales and proposals, fundraising, regulatory compliance, and trust building through content. Each context has different evidence standards, and not all require RCT-level proof. [1]
The evidence ladder runs from literature review (low cost, good starting point) through user surveys, observational studies, PoC (proof of concept), to RCT (highest reliability but most expensive). Japan's Next-Generation Healthcare Industry Council positions evidence building as an industry responsibility that should be approached incrementally. [2]
Practical actions
- Write what you want to prove in one sentence — this is the starting point for everything
- Inventory the evidence you already have (literature, user data, survey results)
- Choose a research design that fits your timeline for the next business milestone
- If you need support from design through publication, consult medical experts early

FAQ
Can a small company build evidence?
Yes. Literature reviews and user surveys are low-cost starting points. The key is clarifying what you want to prove before collecting data.
Is it not real evidence without an RCT?
No. Literature reviews and observational studies can provide sufficient evidence depending on the business phase. A staged strategy is more realistic.
How long does it take to build evidence?
Literature reviews take 2–4 weeks, surveys 1–3 months, PoC 3–6 months, and RCTs 6 months to over 2 years.
