Failure to provide DVT/VTE prophylaxis can constitute medical negligence, but it is not automatically negligent merely because a patient subsequently develops DVT or pulmonary embolism (PE). The central legal question is whether, in the circumstances existing at the time of treatment, a reasonably competent doctor/hospital should have assessed the patient's VTE risk, taken appropriate preventive measures, monitored the patient, and documented the clinical reasoning for the chosen prophylaxis strategy.

The Indian position is particularly important because there is now a directly relevant Delhi High Court decision involving an alleged omission of DVT prophylaxis: Ashok Rajgopal v. State & Anr., Delhi High Court, 1 December 2020.

1. What amounts to "DVT prophylaxis omission"?

DVT prophylaxis generally involves one or more of:

• assessment of VTE/DVT risk;
• early mobilisation;
• leg exercises;
• graduated compression where appropriate;
• intermittent pneumatic compression/DVT pumps;
• pharmacological prophylaxis, such as an anticoagulant, where clinically indicated;
• reassessment when the patient's condition or mobility changes;
• appropriate discharge advice and warning signs.

The legal issue is not simply whether an anticoagulant was given. Mechanical prophylaxis may be appropriate in one patient, pharmacological prophylaxis in another, and no routine pharmacological prophylaxis in a low-risk procedure.

Therefore, a claim based on "no anticoagulant was administered" is materially different from a claim that no VTE risk assessment or preventive strategy whatsoever was undertaken.

2. The most directly relevant Indian case: Ashok Rajgopal v. State

This case is particularly significant for DVT-prophylaxis litigation.

The deceased patient was a 32-year-old doctor who had suffered an ACL injury and travelled from Australia to India for elective arthroscopic knee surgery. The allegations included:

• a recent long-haul flight;
• use of oral contraceptive pills;
• other medication;
• abnormal platelet count;
• inadequate consideration of DVT risk;
• failure to provide appropriate DVT prophylaxis; and
• failure to provide adequate post-operative warning/advice.

The complaint specifically alleged that no chemical prophylaxis was given, although a DVT pump had allegedly been used for a short period after surgery.

A medical board initially stated that the patient had several DVT risk factors and that she had not received DVT prophylaxis either pre-operatively or post-operatively.

However, a subsequent medical-board opinion introduced an important qualification. It stated that, under the ACCP approach, routine chemical prophylaxis is not necessarily indicated for knee arthroscopy in a patient without previous VTE, while mechanical prophylaxis may be used until mobility is restored.

The doctors therefore argued that a DVT pump/GameReady device had been used and that chemical prophylaxis was not routinely required.

What did the Delhi High Court decide?

The Court quashed the FIR, but importantly, it did not decide that the doctors had provided proper DVT care.

The reason was procedural and concerned the standard required for criminal prosecution of a medical professional.

The Court held that there was no expert opinion expressly stating that the doctors were negligent. Consequently, the requirements established by the Supreme Court in Jacob Mathew v. State of Punjab had not been satisfied. The FIR was therefore quashed.

But the Court expressly permitted further expert examination and stated that the investigating agency could take further action if an appropriate expert opinion subsequently supported negligence.

Why this case is extremely useful in a DVT negligence claim

It demonstrates two competing propositions:

For the patient:

A doctor cannot simply say "DVT occurred" or "the procedure was routine." The patient's individual risk factors must be considered.

For the doctor/hospital:

The mere occurrence of DVT does not establish negligence. The applicable medical guidelines, type of surgery, patient's individual risk factors, bleeding risk, mobility, and actual prophylactic measures must all be examined.

The Court's treatment of the case shows why expert evidence is likely to be decisive.

3. Jacob Mathew v. State of Punjab, (2005) 6 SCC 1

This is the leading Supreme Court authority concerning medical negligence, particularly criminal liability.

The Supreme Court emphasized that doctors should not be subjected to criminal prosecution merely because an adverse outcome has occurred. For criminal negligence, the conduct must cross a substantially higher threshold than ordinary civil negligence.

The principle is particularly important where DVT prophylaxis is alleged to have been omitted: an unfortunate DVT/PE or death does not by itself establish criminal negligence.

The Supreme Court required credible independent medical opinion in appropriate criminal proceedings, and Ashok Rajgopal applied that principle directly.

Thus:

Civil/consumer negligence: reasonable professional standard + breach + causation + damage.

Criminal medical negligence: substantially more serious/rash or grossly negligent conduct, with the safeguards laid down in Jacob Mathew.

4. Kusum Sharma v. Batra Hospital, (2010) 3 SCC 480

The Supreme Court's decision in Kusum Sharma is central to determining the standard of care.

The Court's principles include:

1. Negligence may arise from an omission as well as an act.
2. A medical professional must possess and exercise a reasonable degree of skill and knowledge.
3. The law does not demand the highest possible degree of care.
4. A doctor is liable where the conduct falls below that expected of a reasonably competent practitioner in that field.
5. A mere difference of medical opinion does not automatically constitute negligence.

The Supreme Court has subsequently reaffirmed these principles.

Application to DVT prophylaxis

Suppose a patient develops DVT after surgery.

That fact alone is insufficient.

The court would ordinarily ask:

• Was the patient high-risk?
• Was VTE risk assessed?
• What was the nature of surgery?
• How long was the patient immobilised?
• Was there previous VTE?
• Was there recent prolonged travel?
• Was the patient taking OCP/HRT?
• Was there obesity, malignancy, thrombophilia, pregnancy, trauma, etc.?
• Was pharmacological prophylaxis contraindicated because of bleeding risk?
• Was mechanical prophylaxis used?
• Was early mobilisation advised?
• Was prophylaxis continued for the appropriate period?
• What did the applicable medical guidelines recommend at that time?
• Was the treatment decision documented?

The answer must be judged against the reasonably competent practitioner standard, rather than against an idealised or hindsight standard.

5. Savita Garg v. Director, National Heart Institute, (2004) 8 SCC 56

This case is particularly important for hospital liability.

The Supreme Court held that a hospital may be vicariously liable for negligence committed by doctors providing treatment through the hospital. It also rejected the idea that a patient should be expected to know and identify every individual doctor responsible for an omission.

This is highly relevant to DVT claims because prophylaxis is frequently a system-level process, involving:

• surgeon;
• anaesthetist;
• nursing staff;
• physician;
• hospital protocols;
• medication orders;
• nursing charts;
• mobilisation instructions;
• discharge documentation.

Consequently, where a hospital's system failed to identify a high-risk patient or failed to implement an indicated prophylaxis order, liability may extend beyond the individual doctor.

6. Spring Meadows Hospital v. Harjol Ahluwalia, (1998) 4 SCC 39

The Supreme Court recognized that medical negligence can give rise to compensation not only for the immediate physical consequences but also for consequential suffering and, in appropriate cases, the mental agony suffered by family members.

In a DVT/PE case resulting in serious disability or death, damages may therefore potentially encompass:

• medical expenses;
• future treatment;
• rehabilitation;
• loss of income;
• loss of earning capacity;
• attendant/caregiving expenses;
• disability-related expenses;
• pain and suffering;
• loss suffered by dependants;
• mental agony, where legally recoverable.

The actual assessment depends upon the facts and applicable forum.

7. V. Krishnakumar v. State of Tamil Nadu

The Supreme Court has also upheld findings of medical negligence where the treatment fell below the required standard and affirmed the compensatory jurisdiction of consumer fora in appropriate cases.

This illustrates an important distinction:

Death or serious injury is not itself proof of negligence.

There must be evidence establishing that the medical team departed from the applicable standard of reasonable care and that the departure materially contributed to the injury.

8. DVT prophylaxis must be individualized

This is perhaps the most important practical point.

A legal argument saying:

"Every surgical patient must receive anticoagulants, therefore failure to administer anticoagulants is negligence"

would be too broad.

The Ashok Rajgopal case demonstrates why. The medical board relied upon ACCP guidance indicating that routine pharmacological prophylaxis was not recommended for every knee-arthroscopy patient without previous VTE.

Therefore, the stronger legal argument is:

The treating team failed to undertake an adequate individualized VTE risk assessment and, despite identifiable risk factors, failed to adopt any reasonable prophylactic strategy or document why prophylaxis was unnecessary or contraindicated.

That formulation is considerably stronger than simply alleging "no anticoagulant was prescribed."

9. Causation is essential

Even where omission of prophylaxis is proved, the claimant must address causation.

For example:

Duty:
The patient was at significant risk of VTE and required appropriate prophylaxis.

Breach:
The hospital failed to assess the risk or failed to provide indicated prophylaxis.

Causation:
Had appropriate prophylaxis been provided, it is more likely than not that the DVT/PE would have been prevented or its consequences materially reduced.

Damage:
The patient suffered DVT, PE, permanent disability, additional treatment, or death.

The defence may argue that:

• DVT can occur despite appropriate prophylaxis;
• prophylaxis is not 100% effective;
• anticoagulation was contraindicated;
• the patient was low-risk;
• mechanical prophylaxis was provided;
• the patient became mobile promptly;
• the clot developed after discharge independently of the hospital's treatment;
• another cause produced the thromboembolism.

This is why a medical expert's causation opinion can be more important than merely proving that no anticoagulant appears on the medication chart.

10. Documentation becomes extremely important

A DVT-prophylaxis case may turn substantially upon the medical records.

Important records include:

Savita Garg is useful where the hospital attempts to shift the entire evidentiary burden onto the patient, because the Supreme Court recognized the importance of the hospital's ability to produce the relevant treating personnel and records.

11. Civil liability versus criminal liability

This distinction is crucial.

Civil/consumer proceeding

The claimant generally seeks compensation based upon deficiency in service/medical negligence.

The central questions are:

Was there a duty? → Was there a breach? → Did the breach cause injury? → What compensation follows?

The standard is essentially that of reasonable professional care.

Criminal proceeding

The threshold is considerably higher.

Jacob Mathew requires safeguards against criminal prosecution of doctors for ordinary errors of judgment or adverse outcomes. Ashok Rajgopal specifically applied this principle to an alleged DVT-prophylaxis omission and quashed the FIR because the necessary expert opinion supporting criminal negligence was absent.

The Supreme Court has continued to emphasize the distinction between ordinary negligence and the level of negligence necessary for criminal liability.

12. A useful legal test for a DVT-prophylaxis claim

A claimant can structure the case around the following six questions:

A. Was the patient at increased risk?

Identify every risk factor known or reasonably discoverable before the DVT occurred.

B. Was VTE risk actually assessed?

Look for a formal assessment or equivalent clinical reasoning.

C. What prophylaxis was medically indicated?

This must be determined from the clinical circumstances and applicable guidelines—not merely from hindsight.

D. Was the prophylaxis actually provided?

Distinguish:

• pharmacological;
• mechanical;
• mobilisation;
• combined prophylaxis.

E. If prophylaxis was omitted, was there a documented medical reason?

For example:

• active bleeding;
• high bleeding risk;
• contraindication to anticoagulation;
• specific procedure-related considerations.

F. Did the omission cause the eventual injury?

This requires competent medical evidence addressing causation.

13. A particularly important lesson from Ashok Rajgopal

The case provides a useful defence and a useful claimant argument.

The defence can rely on the medical board's conclusion that routine chemical prophylaxis is not required for every arthroscopic knee procedure.

But the claimant can point out that the patient's individual risk factors were alleged to include recent long-haul travel and oral contraceptive use, and that the Court itself recorded the dispute concerning whether those factors had been adequately considered.

Thus, the correct legal question is not:

"Was anticoagulation given?"

but:

"Was the patient's individual VTE risk properly assessed, and did the treating team adopt the level and type of prophylaxis that a reasonably competent practitioner would have adopted in those circumstances?"

14. Bottom-line legal position

In India, omission of DVT prophylaxis can support a finding of medical negligence, particularly where:

1. the patient had identifiable VTE risk factors;
2. the hospital failed to perform or document a meaningful VTE-risk assessment;
3. accepted clinical guidance indicated prophylaxis;
4. there was no legitimate contraindication;
5. neither pharmacological nor appropriate mechanical prophylaxis was provided;
6. the patient was inadequately monitored or mobilised;
7. the omission was a departure from the reasonable standard of care; and
8. competent medical evidence connects that departure with the DVT/PE and resulting injury.

However, DVT occurring after surgery is not, by itself, evidence of negligence. The Ashok Rajgopal litigation is an excellent illustration: despite allegations of multiple DVT risk factors and absent prophylaxis, the criminal FIR was quashed because the necessary expert opinion establishing medical negligence had not been obtained; the Court expressly left open the possibility of further proceedings if a proper expert opinion supported negligence.
