Cervical Manipulation in an Anticoagulated Patient with a Recent Fall
Dr. Nguyen treats a 72-year-old woman, Mrs. Halvorsen, for neck pain and headache after a minor fall. She has hypertension, takes warfarin for atrial fibrillation, and saw her primary care physician two days earlier. Dr. Nguyen does not ask about medications, does not review the PCP note (which was faxed), and does not mention the risk of vertebral artery dissection before performing a high-velocity, low-amplitude cervical manipulation. The note says "CC: neck pain. Tx: C2 adjustment. tolerated well. Return 2 weeks." The next morning Mrs. Halvorsen has vertigo, slurred speech, and double vision; she is hospitalized with a vertebral artery dissection and stroke. The hospital asks Dr. Nguyen for records. Dr. Nguyen calls the patient's daughter and says the stroke was "probably a coincidence" and asks her not to report him.
1. What does informed consent require before cervical high-velocity manipulation, and did Dr. Nguyen meet it?
Read the worked answer
Issue: Whether the rare risk of vertebral artery dissection must be disclosed before cervical HVLA.
Analysis: Informed consent requires a discussion of the diagnosis, the proposed treatment, its material risks, reasonable alternatives, and the consequences of declining care. A risk is material if a reasonable patient would consider it important in deciding whether to proceed. Vertebral artery dissection is rare, but it is a recognized serious risk of cervical manipulation, and the resulting stroke can be catastrophic. The risk therefore must be discussed, along with alternatives such as mobilization, medication, or referral. The discussion must be documented. Dr. Nguyen's note contains no consent discussion at all, and the patient's age, recent fall, headache, and warfarin use made the risk especially relevant.
Conclusion: The consent was inadequate. The failure supports a negligence claim and a professional-discipline charge. The absence of documentation does not prove that nothing was said, but it leaves Dr. Nguyen unable to rebut the patient's account. A proper note would have recorded the specific risks discussed, the patient's questions, and her agreement.
2. Did Dr. Nguyen breach the standard of care in the pre-treatment evaluation?
Read the worked answer
Issue: Whether failing to obtain a medication history, review the PCP note, and screen for red flags breached the standard of care.
Analysis: A reasonable chiropractor taking on a 72-year-old with new neck pain and headache after a fall would obtain a medication history, ask about anticoagulants, review available records, and screen for red flags such as neurological symptoms, severe headache, and trauma. Warfarin increases bleeding risk, and a recent fall raises concern for occult injury. The faxed PCP note was available and ignored. These omissions are not technicalities; they go to whether HVLA was appropriate at all. A reasonable clinician might have deferred manipulation, chosen gentler mobilization, or referred for medical evaluation. Causation is contested in dissection cases, but the documentation gaps make the defense harder.
Conclusion: The Board can find a breach even if the dissection would have occurred anyway. The standard is proper evaluation and decision-making, not a guarantee of outcome. Dr. Nguyen should not alter the record; he should write a factual addendum only if permitted and clearly labeled.
3. What are Dr. Nguyen's obligations after the stroke, including the call to the daughter?
Read the worked answer
Issue: Post-adverse-event duties and the effect of asking the family not to report.
Analysis: After a serious adverse event, the chiropractor should ensure the patient is receiving emergency care, document the event factually, disclose what is known without speculation, provide records as authorized or required, and notify the malpractice carrier. The hospital's request should be handled promptly with a valid authorization or as required by law. Asking the daughter not to report is obstruction. It suggests consciousness of fault, may violate ethics rules on cooperation, and can be treated as a separate disciplinary violation. Calling the stroke "probably a coincidence" before any workup is also misleading.
Conclusion: Dr. Nguyen should stop all contact with the family except through counsel or a formal disclosure process, preserve the original record, and cooperate with the Board. He should not attempt to influence the patient's reporting. The Board may consider the obstruction as an aggravating factor when sanctioning the underlying care.
