Introduction
Medical negligence, also known as medical malpractice, occurs when a healthcare professional or institution fails to provide treatment that meets the standard of care expected of reasonably competent practitioners, resulting in injury, disability, or death to a patient.
While many patients and their families believe that any medical mistake automatically gives rise to liability, the law is far more nuanced. An unsuccessful surgery, a wrong diagnosis, or an unexpected complication does not necessarily mean that negligence has occurred. Medicine is not an exact science, and healthcare providers are not insurers of successful outcomes.
For a medical negligence claim to succeed in Nigeria, the claimant must establish four essential elements:
1. Duty of Care;
2. Breach of Duty;
3. Causation; and
4. Damages.
Failure to prove any one of these elements may result in the claim failing, regardless of how unfortunate the outcome may have been.
This article examines these four elements, their legal significance, and how they are applied in medical negligence cases under Nigerian law.
Understanding Medical Negligence
Medical negligence is a branch of the law of tort and refers to the failure of a healthcare professional or institution to exercise the degree of care, skill, and diligence expected of a reasonably competent practitioner in similar circumstances.
Healthcare providers are expected to:
– Exercise reasonable care;
– Possess adequate professional knowledge;
– Apply accepted medical practices;
– Avoid acts or omissions that may foreseeably harm patients.
Where they fail in these duties and injury results, the law permits the victim to seek compensation.
However, before liability arises, the claimant must prove the four pillars of negligence.
First Element: Duty of Care
Meaning of Duty of Care
Duty of care refers to the legal obligation imposed on healthcare providers to exercise reasonable skill, competence, and diligence in treating patients.
Once a doctor-patient relationship is established, the duty automatically arises.
This means healthcare professionals must act in a manner consistent with what a reasonably competent practitioner in the same field would do under similar circumstances.
When Does Duty of Care Arise?
Duty of care arises when:
– A doctor agrees to treat a patient;
– A patient is admitted into a hospital;
– A nurse undertakes patient care;
– A pharmacist fills a prescription;
– A laboratory conducts diagnostic tests.
The duty exists regardless of whether treatment is free or paid for.
Persons Who Owe a Duty of Care
The duty extends to:
– Doctors;
– Surgeons;
– Dentists;
– Nurses;
– Midwives;
– Pharmacists;
– Medical laboratory scientists;
– Physiotherapists;
– Anaesthetists;
– Radiographers;
– Hospitals and healthcare institutions.
Scope of Duty of Care
Healthcare providers owe duties including:
Proper Diagnosis
Doctors must conduct adequate examinations and order necessary tests.
Competent Treatment
Appropriate treatment must be administered.
Monitoring Patients
Patients must be observed for complications.
Maintaining Confidentiality
Medical records must be protected.
Obtaining Consent
Patients must be informed of risks and alternatives.
Keeping Proper Records
Accurate records are essential.
Examples of Duty of Care
Example One
A doctor in Abuja agrees to treat a patient suffering from chest pain.
Once treatment commences, the doctor owes a duty to diagnose and manage the patient competently.
Example Two
A nurse assigned to monitor a postoperative patient owes a duty to observe and report signs of deterioration.
Example Three
A pharmacist dispensing medications owes a duty to provide the correct drugs and instructions.
Situations Where Duty May Not Arise
Not every interaction creates a duty.
For example:
– Casual medical advice at social events;
– General health articles online;
– Discussions without a doctor-patient relationship.
However, where a professional undertakes treatment, a duty arises.
Second Element: Breach of Duty
Meaning of Breach
Breach of duty occurs when a healthcare provider fails to meet the standard of care expected of a reasonably competent practitioner in similar circumstances.
The law does not demand perfection but requires competence and reasonable care.
Determining the Standard of Care
Courts ask:
“What would a reasonably competent doctor or healthcare provider have done under similar circumstances?”
This standard may vary depending on:
– Specialty;
– Available facilities;
– Emergency conditions;
– Existing medical knowledge.
Examples of Breach of Duty
Misdiagnosis
Treating meningitis as malaria.
Failure to Diagnose
Ignoring obvious symptoms.
Delayed Treatment
Postponing urgent interventions.
Surgical Errors
Leaving instruments inside patients.
Medication Errors
Administering wrong drugs.
Wrong Blood Transfusions
Giving incompatible blood.
Failure to Monitor Patients
Ignoring postoperative complications.
Failure to Obtain Informed Consent
Performing procedures without adequate explanations.
Professional Standards and Expert Evidence
Courts often rely on expert testimony to determine whether a breach occurred.
Medical experts explain:
– Accepted practices;
– Standard procedures;
– Whether the conduct complained of fell below acceptable standards.
Expert evidence is especially important because judges are not medical practitioners.
Difference Between Complications and Negligence
Complications do not necessarily indicate negligence.
Examples:
– Allergic reactions despite precautions;
– Surgical complications despite competence;
– Failure of treatment despite reasonable efforts.
Negligence arises only where there has been a departure from acceptable standards.
Third Element: Causation
Meaning of Causation
Causation refers to the connection between the breach of duty and the injury suffered.
Even where negligence exists, liability will not arise unless the claimant proves that the negligence caused the damage complained of.
This is often the most difficult aspect of medical negligence cases.
The “But For” Test
Courts commonly ask:
“But for the negligence, would the injury have occurred?”
If the answer is no, causation is established.
Examples of Causation
Example One
A surgeon leaves surgical gauze inside a patient’s abdomen.
The patient develops infection requiring further surgery.
The infection would not have occurred but for the surgeon’s negligence.
Therefore, causation exists.
Example Two
A doctor delays diagnosing appendicitis.
The appendix ruptures and causes severe complications.
Prompt diagnosis would likely have prevented the rupture.
Causation is established.
Example Three
A pharmacist dispenses the wrong medication.
The patient suffers kidney failure.
If the wrong drug caused the damage, causation exists.
Situations Where Causation May Fail
Causation may be difficult to prove where:
– The disease was already terminal;
– Multiple medical conditions existed;
– The injury would have occurred regardless of treatment.
Example:
A patient with advanced cancer dies despite delayed diagnosis.
If death was inevitable regardless of treatment, causation may not be established.
Intervening Factors
Third-party actions may break the chain of causation.
Examples include:
– Patient’s refusal of treatment;
– Failure to follow medical advice;
– Subsequent unrelated accidents.
Where these factors become the true cause of injury, liability may be reduced or excluded.
Fourth Element: Damages
Meaning of Damages
Damages refer to actual losses suffered by the patient as a result of negligence.
Without proof of injury or loss, there can be no successful claim.
Negligence without damage is not actionable.
Types of Damage
Physical Injury
Examples include:
– Fractures;
– Organ damage;
– Paralysis;
– Brain injury.
Psychological Harm
Examples include:
– Anxiety;
– Depression;
– Emotional trauma.
Financial Loss
Including:
– Medical expenses;
– Rehabilitation costs;
– Transportation costs.
Loss of Earnings
Where injuries affect employment.
Death
Fatal negligence claims may be brought by dependants.
Categories of Damages Recoverable
General Damages
Compensation for:
– Pain and suffering;
– Emotional distress;
– Loss of enjoyment of life.
These are assessed by courts.
Special Damages
Specific financial losses including:
– Hospital bills;
– Cost of medication;
– Rehabilitation expenses;
– Transportation expenses.
These must be strictly proved.
Future Medical Expenses
Where lifelong treatment is necessary.
Examples:
– Wheelchairs;
– Prosthetics;
– Ongoing surgeries.
Loss of Earning Capacity
Applicable where permanent disability affects employment.
Funeral Expenses
Recoverable in fatal cases.
Loss of Dependency
Dependants may recover compensation for loss of financial support.
Burden of Proof in Medical Negligence Cases
The claimant bears the burden of proving all four elements.
The standard is proof on the balance of probabilities.
The claimant need not prove the case beyond reasonable doubt.
Rather, the evidence must show that it is more probable than not that negligence occurred.
Role of Medical Records
Medical records often provide crucial evidence.
Important documents include:
– Admission records;
– Prescriptions;
– Laboratory reports;
– Surgical notes;
– Nursing charts;
– Discharge summaries.
Poor documentation may itself indicate negligence.
Importance of Expert Witnesses
Expert witnesses help establish:
– Standard of care;
– Breach of duty;
– Causation;
– Extent of injuries.
Their testimony assists courts in understanding complex medical issues.
Common Reasons Medical Negligence Claims Fail
Failure to Prove Duty
No doctor-patient relationship existed.
Failure to Prove Breach
The treatment complied with accepted standards.
Failure to Prove Causation
The injury was unrelated to the alleged negligence.
Failure to Prove Damages
No actual loss occurred.
Can Hospitals Also Be Liable?
Yes.
Hospitals may be liable under:
Vicarious Liability
For negligence committed by employees.
Direct Liability
For:
– Inadequate staffing;
– Defective equipment;
– Poor supervision;
– Unsafe facilities.
Accordingly, both hospitals and individual practitioners may be sued.
Practical Steps for Victims

Early intervention improves the chances of success.
Conclusion
Medical negligence claims are not based merely on unfortunate outcomes or dissatisfaction with treatment. To succeed, a claimant must establish four essential elements: duty of care, breach of duty, causation, and damages.
These four pillars form the foundation of every medical negligence action in Nigeria. Failure to prove any one of them may defeat the claim, regardless of the severity of the injury suffered.
