GURU TEG BAHADUR HOSPITAL, DELHI
INTRODUCTION
EMERGENCY MEDICAL CARE

It involves diagnosis of disease state
and degree of emergency in a short
time coupled with an accurate
judgment and treatment
2
THE EMERGENCY
AND CASUALTY
• We are frequently involved in assessment and
treatment of patients who may be either victims
of violence or accidents or having medical
situations with some legal implications
• We are desired to have adequate knowledge and
training in the forensic aspects of medical care
• Otherwise necessary and significant evidence
can be overlooked, lost, inadvertently discarded,
or its admissibility denied, ultimately resulting in
failure to establish and fix responsibility for the
case in accordance with the law of the land
3
SCOPE
ALL THOSE INVOLVED WITH THE PATIENTS ARE
SUPPOSED TO FOLLOW THE LAWS OF THE STATE
• We must know our responsibilities towards patient,
state & law
• Ignorance of law is not an excuse
• Knowledge of relevant acts & laws is very important
and desirable
Examples: the CPA Act, the MTP Act, the PNDT Act, the
Transplantation of Human Organs Act, the Mental Health Act, the
Registration of Births & Deaths Act, the Motor Vehicles Act, the
NDPS Act, the Drugs & Cosmetics Act, the Protection of Human
Rights Act)

body, mind, reputation or property (Sec.44, IPC)
ASSAULT
• An offer or threat or attempt to apply force to body
of another in a hostile manner (Sec.351, IPC)
MECHANICAL INJURY (WOUND)
• A break of the natural continuity of any of the
tissues of the living body, produced by physical
violence

EXAMINATION OF PATIENTS
IN EMERGENCY & CASUALTY
PURPOSES
1.To assess the patient’s suffering and give
appropriate treatment
2.To prepare a report for:
•
Medical purposes
•
Medicolegal purposes: Personal injury
claim; Public liability; Work-cover;
Medical negligence
9
EXAMINATION OF PATIENTS
IN EMERGENCY & CASUALTY
AIMS
•
To determine nature and extent of illness
•
To assess causation of illness/injury
•
To give prompt and appropriate treatment
•
To determine level of impairment
10
RECEIVING A
PATIENT IN EMERGENCY
THREE WAYS
1. Patient presents on his/her own or
brought by the relatives/attendants
2. Patients/accused is brought by the police
or referred by a court for examination and
reporting
3. Patients is referred from other doctor or
hospital
11
TYPES OF CASES RECEIVED
IN EMERGENCY AND CASUALTY
•
•
•
•
•
•
•
Brought-in Dead
Medical Emergencies
Surgical Emergencies
Trauma Cases: assault, roadside accident,
factory accident, firearm injury, burns injury
Poisonings
Sexual Offence, criminal abortion
Cases referred from courts or otherwise for
age estimation
12
WHO IS A
MEDICOLEGAL CASE
NO STRICT DEFINITION
1.
After history taking and thorough
examination, if the doctor feels that the
circumstances/ findings of the case have
legal implications
2.
The case is brought by the police or referred
by a court for examination and reporting
3.
The case was already attended to by a doctor
and an MLC was registered in the previous
hospital, and now he/she is referred for
further management/ advice
13
IMPORTANT DUTIES IN
MEDICOLEGAL CASES
•
Inform the police
•
After taking consent, examination the patient and
give treatment
•
Do medicolegal formalities and issue medicolegal
certificate as early as possible
•
In serious cases, arrange for recording the dying
declaration: VERY IMPORTANT
•
Don’t accede to request by the patient or the
persons accompanying, not to register an MLC.
Use your own judgment and experience
14
CONFIDENTIALITY
•
Confidentiality must be maintained in all
cases and we must keep secret all
information regarding the patient that is
come across during the course of the
examination
•
Medicolegal reports should be handed over
to the authorized police official only, after
getting them duly received on the carbon
copy of the same
15
TRIAGE
•
Prioritizing patients into categories based on
their severity of illness/ injury, likelihood of
survival and urgency of medical care
•
The goal is to identify high-risk patients who
would benefit from the resources available
•
In Emergency Room, we are the first
responders for triage
•
Assessment must be made quickly and
treatment started
16
RESUSCITATE THE PATIENT
FIRST
•
The cases may be brought conscious,
unconsciousness or dead
•
In the casualty, while attending to a patient, we
should understand that our first priority is to save
the life of the patient
•
Supreme Court ruling: “medicolegal aspects are
secondary to life of patient”
•
While attending to an emergency, we should do
everything possible to resuscitate the patient and
ensure that he/she is out of danger
•
ALL LEGAL FORMALITIES STAND SUSPENDED
TILL THIS IS ACHIEVED
17
RESUSCITATION IN
EMERGENCY MEDICAL CARE
•
Some specific measures in resuscitation and
emergency medical care include:
•
•
•
•
•
•
•
•
•
•
CPR
Mechanical ventilation
Oxygen support & nebulizations
IV fluids & blood transfusions
Gastric lavage
Oral & injectable medications (for pain,
vomiting, breathlessness, allergic reactions,
high-grade fever etc)
Specific antidotes
Wound cleaning & dressings
Limb splintage & immobilization
Certain emergency/ life-saving procedures
18
STEPS OF
THE EXAMINATION
•
CONSENT
•
Should always be taken while examining
and treating a patient
•
Whenever a doctor agrees to treat a
patient there is a doctor patient contract
(Implied Consent) to treat a patient with
reasonable care & skill
•
For examination there is an implied
consent. But for more than examination
and to be valid, the consent must be
competent, freely given, informed,
expressed and specific to the procedure
being performed
19
CONSENT IN A
MEDICOLEGAL CASE
•
In medicolegal cases, an informed
consent includes information that:
1.
The examination to be conducted would be a
medicolegal one and would culminate in the
preparation of a medicolegal injury report,
2.
All relevant investigations needed for the said
purpose would be done, and
3.
The findings of the report may go against the
patient if they do not tally with the history
given (very important)
20
CONSENT IN A
MEDICOLEGAL CASE
“However, a person arrested as accused in a
criminal offence may be medically examined
without his/her consent on the request of a
police officer (of a rank of Sub-Inspector or
higher) or on the orders of the court, if there
are sufficient grounds to believe that such
examination will provide evidence of the
commission of the offence”
21
STEPS OF
THE EXAMINATION
•
In case of examination of a woman
•
It is preferable that a lady doctor
should examine her, or, wherever this
is not possible, a female
disinterested attendant (a nurse, for
example) should be present during
the examination
•
However, in case of a woman who is
an alleged victim of sexual offence,
only a lady doctor can examine her
22
STEPS OF
THE EXAMINATION
•
HISTORY
•
Quickly establish impartiality and
gain the patient’s confidence
•
Establish chronology of events
accurately
•
Distinguish clearly between history
obtained from others and that stated
by the patient
23
STEPS OF
THE EXAMINATION
•
CLINICAL EXAMINATION
•
Start gently and explain every move
•
Assess the mental status
•
Record the vitals (pulse, BP etc)
•
Perform the clinical examination
methodically and thoroughly
24
STEPS OF
THE EXAMINATION
•
CLINICAL EXAMINATION
•
Examine the injuries adequately,
observe the movements carefully,
and assess the impairments (if any)
diligently
•
Be over-conscious of respecting
privacy while undressing
•
Record findings as they are
25
STEPS OF
THE EXAMINATION
•
CLINICAL EXAMINATION
•
Comment on inconsistencies (if any)
between the history given and the
findings of clinical examination
•
Tactics to expose malingering are not
unwarranted
•
Ultimately an objective assessment
of injury/ impairment is made
26
INVESTIGATION OF
WOUND CHARACTERISTICS
•
The investigation of undiagnosed trauma
often begins with the evaluation of wound
pattern characteristics
•
Detailed documentation of the appearance of
the wound may be the identifying factor in
determining the type of weapon used to inflict
the injury
27
INVESTIGATION OF
WOUND CHARACTERISTICS
•
The documentation should include the
location of the injury, exact measurements
and other characteristics of bruises,
abrasions, cuts, lacerations, stab wounds and
entry/exit wounds
•
Diagrams, body maps or photography are
helpful in reconstructing injury patterns in
subsequent investigations or at autopsy

MARKS OF IDENTIFICATION
•
MUST BE NOTED IN AN MLC
•
Ideally two scar marks should be noted
•
Otherwise thumb impression should be
taken (Male-Lt, Female-Rt, Infant-Foot)
•
Witnessed signatures of the patient
can help in identification
•
All the entries should be made
promptly and correctly
50
PRESERVATION OF
EVIDENCE IN AN MLC
•
Hospital emergency departments are
regularly required to be in contact with
essential evidence in criminal cases
•
Trace and physical evidences are very
important and useful to establish the facts of
a crime
•
Recognize the importance of recovering
possible items of evidence in a legally
acceptable manner in case of an MLC
51
PRESERVATION OF
EVIDENCE IN AN MLC
•
The most common types of evidence are
clothing, bullets, bloodstains, hairs, fibres,
and small pieces of material such as
fragments of metal, glass, paint, and wood
•
Appropriate specimens / samples (such as
blood, urine, semen, saliva, gastric aspirate,
vaginal swab, hair, nail etc) should also be
taken from the patient wherever required
52
PRESERVATION OF
EVIDENCE IN AN MLC
•
Collection and preservation of medicolegal
evidence should be done with proper labeling
and sealing under the doctor's supervision
•
Documentation must reflect the accurate
identification, description, and security of
medicolegal evidence
53
PRESERVATION OF
EVIDENCE IN AN MLC
•
The samples should be handed over to the
police official concerned, along with the
medicolegal report and a proper requisition
letter detailing the tests to be conducted on
such samples
•
If the samples have been collected on the
request of the police, the fact is to be
mentioned in the report and no requisition is
necessary

59
PREPARATION OF
MEDICOLEGAL REPORT
•
Medicolegal report (MLR) should be prepared
immediately after the examination of a
medicolegal case is done
•
It should be prepared in duplicate, preferably
with a ball-point-pen, in a clear and legible
handwriting
•
Cutting/ overwriting etc should be avoided as
much as possible and all corrections should
be properly initialed
•
Abbreviations of any sort should be avoided
60
DYING DECLARATION
•
It is a statement by a person who is conscious
and knows that death is imminent concerning
what he or she believes to be the cause or
circumstances of death that can be introduced
into evidence during a trial in certain cases
•
It should be got recorded in all serious
medicolegal cases
•
It is better to get it recorded from magistrate. In
case a delay is likely, the doctor should himself
record dying declaration
•
Doctor should certify compos mentis in both
the situations
61
IN CASE OF DEATH
OF A MEDICOLEGAL CASE
•
Do not issue death certificate or hand over
the dead body to the relatives of the
deceased
