Medical Negligence (Malpractice) - FMT | BHMS 2nd Year | 5 Marks

Definition

• Negligence (Justice Baron Alderson, 1856): "The omission to do something which a reasonable man could do, or doing something which a prudent and reasonable man could not do."
• Medical negligence is a part of the Law of Torts - a civil wrong for which the sufferer can seek compensation.

Essential Elements (4 Ds - Lord Wright, 1934)

The patient must prove all four elements by a preponderance of evidence (more likely than not).

Types of Medical Negligence

1. Civil Negligence

• A patient sues the doctor in a civil court for compensation for injury suffered due to negligence.
• A doctor sues the patient for fees, and the patient alleges negligence as a defense.

2. Criminal Negligence

• When the patient wants the doctor to be punished (not just compensated).
• Requires a higher degree of negligence - gross, reckless, or wanton disregard for patient safety.
• Punishable under Section 106 BNS (previously Section 304A IPC).

3. Corporate Negligence

• Negligence on the part of a hospital/institution rather than an individual doctor.
• Hospital is vicariously liable for the acts of its employees.

4. Contributory Negligence

• The patient himself contributes to the harm by his own negligence, e.g., not following medical advice, concealing history, or not taking prescribed medicines.
• Reduces or eliminates the doctor's liability.

Doctrine of Res Ipsa Loquitur ("The thing speaks for itself")

1. In the absence of negligence, the injury would not have occurred ordinarily.
2. The doctor had exclusive control over the injury-producing instrument or treatment.
3. The patient was not guilty of contributory negligence.

• Prescribing an overdose causing ill-effects
• Giving poisonous medicine by mistake
• Leaving a surgical instrument/sponge inside the body
• Operating on the wrong limb

Vicarious Liability

Defenses Against Medical Negligence

1. No duty owed to the plaintiff
2. Duty discharged according to prevailing standards (Bolam test)
3. Misadventure - unforeseeable, unavoidable accident
4. Error of judgment - genuine error without negligence
5. Contributory negligence by the patient
6. Res judicata - matter already decided by a court (appeal only)
7. Limitation - suit must be filed within 2 years (3 years for breach of contract)

Instances of Medical Negligence (Examples)

1. Refusal to admit patients requiring urgent hospitalization
2. Failure to obtain informed consent
3. Failure to examine the patient personally
4. Failure to take proper history
5. Wrong diagnosis leading to wrong treatment
6. Failure to refer when specialist care is required
7. Prescribing a drug the patient is known to be allergic to
8. Abandonment of a patient without proper notice

Prevention of Medical Negligence (5 Rs)

Key Landmark Cases

• Bolam vs Friern Hospital Management Committee (1957): Doctor is not negligent if he acts in accordance with a practice accepted by a responsible body of medical opinion ("Bolam test").
• Roe vs Ministry of Health: Percolation of Nupercaine - held as misadventure (risk unknown at that time), not negligence.
• Hatcher vs Black (1954): Lord Denning - "Negligence is like a dagger that wounds a doctor's professional reputation."

Medical Negligence - Simple Language Version

What is Medical Negligence?

The 4 Things That MUST Be Proven (4 Ds)

1. Duty - The doctor had a responsibility to treat that patient (doctor-patient relationship existed)
2. Dereliction - The doctor did NOT do his job properly (skipped something or did something wrong)
3. Direct Cause - That mistake is what caused the harm (not something else)
4. Damage - The patient actually got hurt (injury, disability, death, prolonged illness)

If even ONE of these 4 is missing, there is NO negligence legally.

Types of Negligence

Res Ipsa Loquitur - "The Fact Speaks For Itself"

• Doctor left a scissor/sponge inside the patient's abdomen after surgery
• Operated on the wrong leg
• Gave a 10x overdose of medicine

Vicarious Liability

Defenses - How Doctors Protect Themselves

• "I followed standard practice" - Bolam test: if a recognized group of doctors would have done the same thing, the doctor is safe
• "It was a misadventure" - an unforeseeable accident, not carelessness
• "Error of judgment" - genuine honest mistake, not recklessness
• "Patient was also at fault" - contributory negligence
• Time limit passed - patient must file case within 2 years

How to PREVENT Negligence (5 Rs - Easy to Remember)

Common Examples of Negligence in Real Life

• Not asking about allergies before giving a drug
• Not taking informed consent before surgery
• Discharging a patient too early
• Failing to refer a serious case to a specialist
• Not examining the patient personally and prescribing blindly

What is NOT Negligence

• A patient dies despite the best possible care
• A rare, unpredictable drug reaction occurs
• Honest diagnostic error when the case was genuinely difficult
• A complication that is a known risk of a procedure (if patient was informed)

Corpus Delicti - FMT | BHMS 2nd Year

What Does It Mean?

Simple Example

What Does Corpus Delicti Include?

The Key Legal Rule

1. Prosecution must have enough corroborating evidence that the essential parts of a crime occurred - BEFORE charging anyone.
2. If corpus delicti is NOT established, the case cannot proceed in court.
3. A person cannot be convicted based on confession alone - there must be supporting evidence.
4. However - the court CAN pass a death sentence even if the body is not recovered, provided there is strong eyewitness or other corroborative evidence.

Why Is It Important in Forensic Medicine?

• Identifying the dead body - proving it is indeed a human being and identifying who it is
• Establishing cause of death - natural, accidental, suicidal, or homicidal
• Documenting injuries - type, nature, weapon used
• Collecting forensic evidence from the body

Methods Used to Establish Identity (as part of Corpus Delicti)

• Age, Sex, Religion, Complexion
• Stature and body development
• Fingerprints, footprints
• Teeth and dental patterns
• DNA fingerprinting
• Superimposition
• Personal belongings

• Speech and voice
• Handwriting
• Gait (style of walking)
• Habits, memory, education

Positive (Undeniable) Identification Methods

1. Fingerprints / Footprints / Lip prints
2. Dental patterns
3. DNA analysis
4. Frontal sinus pattern (unique like fingerprints on X-ray)
5. Bone comparisons

One-Line Summary for Exam

Corpus Delicti = Proof that a crime actually occurred. It includes the body of the victim + all physical evidence of foul play. No one can be convicted without first proving that a crime happened.

Data for Identification - FMT | BHMS 2nd Year

What is Identification?

Since no single feature is reliable alone, a combination of features is always used. Sex, Age, and Stature are the three PRIMARY characteristics of identification.

The 14 Types of Identification Data

1. Race and Religion

• Complexion - Indians = brown, Europeans = fair, Negroes = black (limited value as it changes with decomposition/burning)
• Hair - straight (Caucasians/Mongolians), woolly/curly (Negroes)
• Skull characteristics:

• Hindu males - not circumcised, sacred thread, tuft of hair, pierced ears, caste marks on forehead
• Hindu females - vermilion on forehead/scalp parting, silver toe ornaments, tattoo marks, nose ring in left nostril
• Muslim males - circumcised, corns/callosities on knees and feet (from prayer posture)
• Muslim females - nose ring in nasal septum, multiple ear piercings, generally NO tattoo marks

2. Sex

• Pelvis - most reliable bone for sex determination
  • Female pelvis: wider, rounder, greater sciatic notch angle (>90°)
  • Male pelvis: narrower, heart-shaped inlet, smaller sciatic notch (<90°)
• Skull - males: prominent brow ridges, mastoid process, chin; females: smoother, more rounded
• Long bones - males have longer, thicker, heavier bones

3. Age

• Physical features - skin, hair (grey/white), wrinkles, posture
• Teeth eruption - most reliable in children (milk teeth → permanent teeth)
• Ossification of bones - appearance and fusion of bone centres (used in medico-legal age estimation)
• X-rays - for bone age

4. General Development and Stature (Height)

• Stature can be estimated from long bones (especially femur and tibia) using regression formulae
• Nutritional status, muscle build, and weight give additional clues

5. Complexion and Features

• Skin color, facial structure, eye color, nose shape
• Limited value in decomposed or burned bodies

6. External Peculiarities ⭐ (Very Important)

• Moles and birthmarks
• Scars (surgical, injury, vaccination)
• Tattoo marks - give clues about community, profession, prison history
• Occupation marks - e.g., callosities on hands of laborers
• Malformations - extra fingers (polydactyly), fused toes, etc.
• Wounds - old healed injuries

7. Anthropometric Measurements (Bertillon System)

• Height, arm span, length of head, width of head
• Length of right ear, left foot, left middle finger, left little finger
• Width of cheeks

8. Fingerprints and Footprints ⭐ (GOLD STANDARD)

• Most reliable method of identification
• Fingerprint pattern is formed by the 4th month of fetal life and never changes throughout life
• Even identical twins have different fingerprints
• Types of patterns: Loop (most common ~65%), Whorl (~30%), Arch (~5%)

9. Teeth (Dental Identification) ⭐

• Teeth survive fire, decomposition, and trauma better than other tissues
• Dental formula helps estimate age
• Dental records, fillings, crowns, and missing teeth are used for comparison
• Gustafson's method - estimates age from tooth wear, root resorption, etc.

10. Personal Effects

• Clothes, jewelry, ID cards, wallet contents, pocket items
• Can give quick presumptive identification (but not conclusive)

11. Handwriting

• Unique to each person; used to identify living individuals
• Analyzed by a forensic document examiner

12. Speech and Voice

• Tone, accent, language, speech defects
• Voice spectrography (voiceprint) used in modern forensics

13. Gait, Tricks of Manner and Habit

• The way a person walks, stands, gestures
• Recognized by people who know them well
• Useful in CCTV footage analysis

14. Memory and Education

• Knowledge, skills, language ability
• Useful when all other features fail (e.g., amnesia cases)

Special Identification Methods (Positive/Undeniable)

1. Fingerprints / Footprints / Lip prints
2. Dental patterns
3. DNA fingerprinting - most modern, most accurate
4. Frontal sinus X-ray pattern - unique like fingerprints
5. Skull suture patterns
6. Bone comparison (normal and abnormal)
