Supratherapeutic INR, Shoulder Pain, and Requests for Electroacupuncture and Cupping
A 72-year-old retired teacher presents with a 6-week history of right lateral shoulder pain after a fall. Pain is 7/10 with overhead reach, and she has a painful arc from 70 to 110 degrees. She takes warfarin for atrial fibrillation; today's INR is 3.4, above her target range of 2.0-3.0. She also takes aspirin 81 mg daily and used naproxen until two days ago. Examination shows tenderness at GB21, SI11, and LI15, with no swelling or bruising. She has read that electroacupuncture and strong cupping work well for shoulder pain and asks to start both today. The clinic has a four-channel electroacupuncture device and glass cups. She has no pacemaker, no fever, and no history of bleeding disorder. She is eager to begin and says she can stay for 45 minutes.
1. How would you assess and modify her requested treatment today?

The key issue is bleeding risk, not the shoulder diagnosis. An INR of 3.4 is above her target range, and warfarin plus aspirin plus recent naproxen creates additive risk. Strong cupping causes capillary rupture and ecchymosis by design, so it is inappropriate today. Electroacupuncture adds local tissue trauma and stronger stimulation, and there is no urgency that justifies that risk. I would defer both and contact her prescriber about the INR before any elective needle treatment. If she understands the tradeoff and still wants care, I would use fine-gauge manual needles, treat distal points such as SI3, SJ5, and GB34, and avoid deep needling at GB21 and SI11. I would use gentle manipulation, apply pressure on withdrawal, and observe for oozing. I would not promise the same result as a full treatment. If the prescriber advises holding warfarin or adjusting the dose, I would wait until the INR is in range. The reasoning is that the examination does not require an urgent intervention, while a large hematoma in a thin, anticoagulated shoulder could impair function and require further care.
2. What informed-consent and documentation steps are required if you proceed with any needling?
Read the worked answer
Consent must be specific to the modified plan, not a generic form. I would explain that the INR is above target, that aspirin and recent naproxen increase bleeding risk, and that bruising or hematoma is more likely even with fine needles. I would state what I am not doing today, namely strong cupping and electroacupuncture, and why. I would document the INR value, the medications, the prescriber contact and response, the points and needle gauge used, the depth and manipulation, and the post-treatment observation. I would also document that the patient was given the option to defer treatment and that she agreed to the modified plan. If she declines the safer plan, I would record that the riskier plan was declined and offer acupressure or another non-needle option. Good documentation should make clear that the decision was a clinical judgment based on current data, not an oversight.
3. She returns three days later with a 4 cm purple, tender hematoma at SI11. How do you manage and what do you document?

I would first assess the hematoma: size, tension, warmth, distal neurovascular status, and whether it is expanding. A stable, non-expanding hematoma in an anticoagulated patient can usually be managed conservatively with compression and cold application early, then gentle warmth after the acute phase. I would not needle or massage the area, and I would avoid aspiration unless it is large, tense, or causing compartment symptoms. I would check whether she has new bruising elsewhere, ask about bleeding gums or dark stools, and advise her to contact her prescriber because the hematoma occurred with an INR above target. If the area is hot, spreading, or accompanied by fever, I would refer for infection evaluation. Documentation should include the point, needle size, depth, INR at the time, onset, current size, neurovascular findings, advice given, and follow-up plan. The reasoning is that the hematoma is a foreseeable adverse event of needling an anticoagulated patient, and the record must support both continuity of care and risk management.
