- A clinical evaluation report (CER) describes the relationship between clinical data and a medical device’s safety and performance.
- Adherence to proper scope, methodology, and continued post-market follow-up is vital, especially when looking at needs for regulatory expectations under EU MDR and the regulations in India.
- Within India, the Central Drugs Standard Control Organisation (CDSCO) and the professional and quality standards of the Medical Devices Rules 2017 provide the regulatory framework for medical devices, and by inference, for clinical evaluation.
- Manufacturers face challenges stemming from awareness of the relevant clinical data, identifying how to fill evidence gaps, assessing the benefit-risk ratio, and updating throughout the medical device lifecycle.
- Manufacturers that utilize the CER process in an early stage, internal team alignment, and keeping the document updated minimizes regulatory risks and has a rapid time-to-market.
Introduction
A Bengaluru-based startup has created an innovative portable dialysis machine. They are confident in the engineering design, completed bench testing, and committed hospitals. But when they apply to the regulatory authority, the reviewer points out the one thing they are missing: a structured document that describes how real-world clinical data demonstrates safety, how post-market surveillance will be done, and how benefit versus risk was determined. In other words, a clinical evaluation report.
Without a clinical evaluation report, the startup is at a standstill, delays occur, costs rise, and investor confidence wanes. This is more than just a piece of paperwork — this is a strategic milestone. In this article, we will break down how to prepare a clinical evaluation report that will inform the stakeholders what they need to know, fits into the regulatory framework in India, and will help avoid key pitfalls.
What is a Clinical Evaluation Report (CER)?
The term “clinical evaluation report” refers to the formalised document that summarises the results of clinical evaluation for a medical device. According to industry guidance post-EU Medical Device Regulation 2017/745, the CER must show how clinical data (both pre-market and post-market) support a device’s safety and performance for its intended use.
In the Indian context, while the regulations are not as prescriptive as the EU’s MDR for every device class, the regulatory authority expects evidence of clinical safety and performance, especially for higher-risk devices.
In simple terms: the CER is the bridge between design/bench data and real-world use. It says: “Here is the device. Here is how it works. Here is the evidence. Here is how we monitor it on-going.”
Why the CER is important
- For regulatory approval: Many notified bodies and regulatory authorities will refuse or delay approval if the CER is poorly structured or incomplete.
- For lifecycle management: The CER is not a one-time submission but part of an ongoing process of monitoring and updating as new data emerge.
- For risk management: It enables the manufacturer to document how risks have been identified, mitigated and monitored via clinical data.
- For commercial credibility: Investors, partners and healthcare customers expect assurance that the device has undergone rigorous clinical evaluation.
Clinical Evaluation Report under Indian Medical Device Rules 2017
Understanding the regulatory backdrop in India is essential for tailoring your clinical evaluation report accordingly.
The Medical Devices Rules 2017 & CDSCO
In India, all medical devices are regulated under the Central Drugs Standard Control Organisation (CDSCO) via the Drugs & Cosmetics Act, with the Medical Devices Rules of 2017 creating a formal framework. The rules classify devices into four classes (A, B, C, D) based on risk: low to high.
For device registration, CDSCO may require clinical investigations or, in some cases, submission of relevant clinical evidence from other jurisdictions.
Clinical Evaluation & Investigations: What India expects
A recent review notes that in India, clinical investigations (i.e., human studies) are required for Class B, C, D devices if no predicate device exists and/or the device is novel. For devices already marketed in major countries (US, EU, Japan etc.) for 2 years, local clinical investigation may be waived.
Implications for the CER
Even if a full clinical study is not mandated in India, your CER must show:
- Evidence from published literature, equivalent devices or clinical experience
- Post-market vigilance or surveillance plan
- The benefit-risk assessment and how you address Indian patient population considerations
In short: the regulatory expectation is shifting towards more structured evidence and ongoing evaluation.
Key Components of an Effective Clinical Evaluation Report
When you sit down to draft a CER, treat it as the narrative of how your device stands up clinically. Below are the core sections you should include.
1. Scope and objectives
Define precisely what the CER covers: which device version, which indications, which patient population. In the context of the CER you should state your intended use, contra-indications, and user environment. This sets boundaries for what the report will address.
2. Device description & state-of-the-art
Here you describe the device and how it compares with available technologies. The state-of-the-art review shows you understand existing solutions and how your device fits or improves. This contextualises your clinical evidence and helps reviewers assess whether your device offers additional benefit.
3. Clinical data identification (Literature review, equivalence, internal studies)
You must demonstrate you have systematically searched for relevant clinical data: peer-reviewed papers, equivalence to an existing device, manufacturer’s internal data. The methodology of search, inclusion/exclusion, quality appraisal should be transparent.
4. Critical appraisal of clinical data
Merely collecting the data is not sufficient: you must critically analyse it for validity, applicability and relevance to your device and patient population. For example: Was the study design appropriate? Was the patient cohort similar to Indian patients? Are there significant differences?
5. Risk–benefit analysis
This is a central part of the CER. You must weigh residual risks (i.e., risks that remain after mitigation) against the clinical benefits. If there are adverse events, you should document how they relate to the device and how they are mitigated in your design or instructions.
6. Post-market surveillance / real-world data / clinical follow-up
A good CER does not stop at pre-market; it includes how the manufacturer will monitor device performance in the market. This is particularly important for India where patient populations, usage conditions and health infrastructure may differ from other geographies.
7. Conclusion & recommendations
Your CER should end with a clear conclusion: does the clinical evidence support the safety and performance of the device for the intended use? Are there gaps? What actions (e.g., post-market study) are planned?
8. Appendices
These might include search strategy details, raw data tabulation, clinical study summaries, equivalence checklists, and user complaint summary tables.
How to Prepare a Clinical Evaluation Report for the Indian Market
When preparing the report for Indian regulatory submission or for an Indian-based manufacturer, keep these additional pointers in mind:
Address local patient population
Indian patients may differ in anatomy, disease prevalence, co-morbidities, or socio-economic factors compared with Western populations. If your clinical evidence comes entirely from abroad, include a discussion on applicability to India or plan for Indian-specific data collection.
Reference Indian regulatory expectations
Mention how your CER aligns with the expectations of the Medical Devices Rules, 2017 and the oversight of CDSCO. Demonstrating compliance with these will reduce regulatory risk.
Plan for post-market surveillance in India
Given the unique use-case environments in Indian healthcare settings, your post-market surveillance plan should specifically address Indian hospitals, usage practices, maintenance environment, user training. This assures the regulator that Indian-specific risks are managed.
Use Indian case-studies or examples where available
If your company has prior experience in India (e.g., another device version used in an Indian hospital, or Indian user feedback captured), include it. For example, a manufacturer of a pulse-oximeter may reference Indian hospital usage where ambient conditions, patients with darker skin tones, or different power supply conditions were present. Using real stories demonstrates credibility.
Consider cost-sensitivity and health-system variability
In India the cost, infrastructure availability, device maintenance and healthcare staff training may differ. Your CER should reflect how these factors have been addressed in your benefit-risk evaluation and usage instructions.
Common Mistakes and How to Avoid Them
From my experience working with device manufacturers in India, here are frequent traps and mitigation strategies.
Treating CER as a one-time, static document
The clinical evaluation report is part of a process. If the manufacturer submits it and then never revisits it, they risk non-compliance. The regulatory bodies increasingly expect that clinical data is monitored throughout the device lifecycle.
Solution: Build internal process for periodic review, trigger-based updates (e.g., new user complaints, adverse events, competitor data), version control.
Over-relying on equivalence without justification
Some manufacturers choose an equivalent device to reuse clinical data. But regulators will challenge whether equivalence is valid in design, patient population, intended use and risk profile.
Solution: Document thoroughly how equivalence was determined—include design comparison, materials used, patient outcomes, risk profiles, differences analysed.
Poorly documented literature search
A CER may fail because the literature search lacks transparency or rigour: missing criteria, unclear databases, bias in inclusion.
Solution: In the search section, include search strings, date range, inclusion/exclusion criteria, number of articles found, how many included, how data extracted.
Ignoring local context
Latent assumption: “The device worked in the US/EU so it will work in India the same way.” That can be risky.
Solution: Explicitly comment on the Indian context: patient demographics, hospital environment, usage conditions, maintenance challenges. If necessary, plan for bridging study or user verification in India.
Weak post-market plan
If you submit a CER but cannot demonstrate how you will monitor performance, handle complaints, or plan corrective actions, you leave yourself exposed.
Solution: Develop a robust post-market surveillance (PMS) plan—monitoring metrics, feedback loops, complaint databases, device failures, user training records, field corrective actions.
Implementing a Clinical Evaluation Report for Market Success
Let’s consider “AlphaMed Technologies”, an Indian-based manufacturer of wearable ECG monitors. They had a version sold in Europe and the US. They now wish to launch in India.
- They first drafted a CER based on their existing clinical studies in Europe.
- During appraisal, they realised their user group (older Indian population with higher incidence of diabetes and hypertension) differed from the European cohort.
- They added a bridging analysis comparing Indian demographics to their study cohort, and proposed a six-month field-study in two Indian hospitals to collect local evidence.
- They included a post-market plan specifically for India: user training across tier-II cities, monitoring web-portal feedback, and regional service hubs.
- The regulator accepted the submission with minor queries and the device got clearance within expected timeframe.
