Introduction
The impact of evidence-based medicine (EBM) on clinical decision-making has expanded significantly, as it gained prominence over the past fifteen years. This approach also affects the court proceeding, as the judges must evaluate the medical data prior to the judgment. The legal professionals have the need to develop medical skills to assess the vast amount of medical data presented in the proceedings as scientific evidence for medico-legal cases [1].
The Legal Challenge of Evaluating Medical Evidence
Judges often face the problem of handling medical data for medical cases prior to making decisions without medical guidance. They should navigate the clinical data as evidence for medico-legal cases. Only the peer-reviewed research was considered valid in the legal cases. As clinical studies involve studying multiple population outcomes rather than individual cases, the court may struggle to apply the data to a single patient, especially in severe medical cases.
Legal professionals should evaluate whether clinical evidence is valid, credible, and applicable. This is particularly essential when deciding whether to admit expert guidance based on clinical studies. As a result, courts have adopted standard methods for scrutinizing medical evidence [2].
The Evolution of Admissibility Standards in Court
From Frye to Daubert: Shift in Legal Standards
The Frye test states that research evidence be “generally accepted” by the relevant scientific community prior the submission in court [2]. However, this approach was shifted by the Daubert standard in 1993, when the U.S. Supreme Court ruled that Federal Rule of Evidence 702 [3] governs the admissibility of expert guidance [4].
Under Daubert, judges work as “gatekeepers,” assuring that expert testimony is based on trustable scientific structure. The court assesses medical evidence based on four factors:
- Testability—Is the method or procedure testable?
- Peer Review—Is the method undergone peer review process?
- Error Rate—Is there any potential error rate, and is there any standard available for controlling it?
- Acceptance—Is the method accepted by the scientific expert community?
This standard indicates the credibility and importance of expert testimony rather than accepting it based on consensus [4].

Evidence Speaks Better Ethics:
The incorporation of scientific research studies will give confidence on decision making. This is based on the principle that the physician who follow the EBM will provide the optimized medical care with the support of evidence.
A British researcher Archie Cochrane stated that extensive medical therapies was using medicine that lacks knowledge of safety and efficacy. This led to the application of EBM on the clinical practice which have strong ethical support by systematically reviewing all the relevant studies for diagnosis, prevention and treatment of patients.
As EBM empathises with high-quality treatment, ethical choices based on the EBM will provide better patient outcomes. However, American pediatricians and obstetricians tend to underestimate neonatal survival rates and the likelihood of freedom from disability. This will affect the efficiency of treatment. When the obstetricians assume a neonatal survival rate, they may be more inclined to perform a caesarean and transfer a mother to tertiary care. [5].
Validity and application of evidence:
EBM should be evaluated for the relevancy related to the patient and treatment. The critically appraised studies should be supported by meta-analysis, randomized clinical trials, case control studies, and cohort studies.
It is crucial to ask two questions before appraising evidence:
1.Is the evidence valid for the case?
- Is it useful to the patient? [6].

Limitations of Medical Evidence on Ethical Cases:
There are some problems associated with the use of medical evidence on the ethical cases.
- Physicians face problems that some clinical cases have no medical evidence at all for treatment.
- In some cases, the available evidence does not have conclusion, irrelevant to the specific cases, or poor quality.
• The bias in the study including, publication bias, selection bias, information bias could affect it’s applicability [5].

Example: There are limited clinical trial data available for rare diseases like Amyotrophic Lateral Sclerosis (ALS) for effective treatment. If no definitive treatment guideline available for ALS, the court may find it difficult to determine the negligence in a medical malpractice case.
How EBM Supports Legal Analysis
The uses of EBM in the court strongly match with the fundamentals determined in Daubert. EBM connects the best available clinical evidence, medical expertise, and patient suggestions to assist clinical decision-making. Since legal professionals evaluate the reliability of medical studies, understanding EBM concepts becomes essential for judges, attorneys, and law librarians [1].
Case study example:
Bolam v. Friern Hospital Management
Mr. Bolam was treated in Friern Hospital in London for a mental health condition. He underwent electroconvulsive therapy (ECT) in this treatment. But he suffered a bone fracture during the treatment, which led to serious injury. He sued the hospital management, claiming that the proper care and the muscle relaxants were not given during the ECT, leading to a bone fracture.
Legal question:
The legal question is whether the hospital provided standard of care and the ECT was done in accordance with proper medical standards.
Decision:
The expert provided evidence on the cases by EBM approach which suggest that the ECT was a valid treatment even without muscle relaxants. The court issued that the hospital and its staff did not commit negligence and followed the proper procedure during the treatment [7].
Why EBM Matters in Medico-Legal Cases
- Help Expert Testimony: EBM ensures that medical suggestions presented in court are backed by high-quality scientific research data rather than mere expert opinions [1].
- Improves Legal Scrutiny: By following EBM principles, courts can better establish whether a medical approach is scientifically correct and clinically matches.
- Matches with Legal Standards: The goal on peer-reviewed research articles, reliability, testability, and mirrors the Daubert criteria for admitting expert suggestions [4].
The Increasing Need for Medico-Legal Services
Given the rising difficulties of medical data evidence in litigation, medico-legal professionals should be equipped with modern methods to assess clinical studies. Courts, law firms, and healthcare litigation experts can advantage from specialized medico-legal services with peer-reviewed research articles to assure the reliability of medical testimony [1].
Key Services for Medico-Legal Professionals
- Medical Literature Review: Reviewing the existing clinical studies relevant to medico-legal services.
- Expert Testimony Analysis: Evaluating the liability of expert opinions based on the principles of EBM.
- EBM Training for Legal Teams: Providing trainings and workshops on understanding and using EBM in medico-legal court proceedings.
- Case-Specific Clinical Research: Providing evidence-based analysis from clinical studies specific to the legal cases [8].
Conclusion
As courts demand higher scrutiny of clinical data evidence, medico-legal professionals should adapt by integrating EBM into their medico-legal strategies. By utilizing Daubert’s principles and EBM methodologies, legal professionals can assure that research evidence is both liable and permissible [4].
For judges, attorneys, and law librarians, mastering EBM based medico-legal analysis is crucial for navigating difficult healthcare litigation and clinical malpractice cases efficiently [1].

Conclusion
For Medico-legal professionals working on medico-legal cases, mastering medical literature search strategy is crucial. MEDLINE, PubMed and MeSH provide powerful tools to:
- retrieve authentic medical research.
- substantiate medico-legal statement with medical research evidence.
- utilize the credibility of expert statement.
By insisting defined search strategies, Medico-legal authors can assure that the medical research evidence presented in court is clear, significant, relevant, thorough and scientifically sound [3].
