Hip Fracture on Apixaban: Timing, Anesthesia, and Shared Decisions
Mrs. K, 82, fell at home and has a displaced femoral neck fracture. She takes apixaban 5 mg twice daily for atrial fibrillation, and the last dose was 14 hours ago. eGFR is 54, platelets are 190,000, Hb is 10.8 g/dL, and INR is 1.1. She is alert with mild baseline cognitive impairment; her daughter holds durable power of attorney for health care. The surgeon proposes waiting up to 72 hours, while anesthesia offers either general anesthesia earlier or spinal anesthesia after an adequate apixaban washout. The family asks why surgery cannot happen tonight, and the unit is short of beds.
1. Analyze the competing risks and outline how the team should reach a decision.
Read the worked answer
Risk of waiting
- Delay beyond roughly 24-48 hours in a frail older adult is associated with more delirium, pressure injury, pneumonia, VTE, and higher mortality.
- Immobility and pain also worsen deconditioning and glycemic control.
Risk of operating early
- Residual apixaban effect raises intraoperative and postoperative bleeding risk.
- If neuraxial anesthesia is used too soon after apixaban, there is a risk of spinal or epidural hematoma, which can cause permanent paralysis. Published regional anesthesia guidance generally calls for holding apixaban for about 72 hours before neuraxial techniques, and renal impairment may prolong the effect. Institutional protocols and current guidance must be verified.
Decision process
- A shared discussion among the surgeon, anesthesiologist, and internist or hospitalist, ideally within hours, not days.
- A reasonable framing is early surgery under general anesthesia versus later surgery with spinal anesthesia, weighing delirium and respiratory risk against bleeding risk.
- The daughter should be included as the health care agent once options are explained.
Nursing role
- Ensure the decision and rationale are documented, and flag any new bleeding, bruising, or neurologic change.
2. What nursing priorities apply to Mrs. K while she waits, and which are easiest to overlook?
Read the worked answer
Priorities
- Pain control: multimodal analgesia, with attention to oversedation and delirium in an older adult.
- Delirium prevention: orientation, glasses and hearing aids, sleep protection, hydration, early mobilization as permitted, and family presence.
- Skin and positioning: pressure-relief, heel protection, and careful log-roll or hip precautions per the plan.
- VTE prevention: mechanical prophylaxis, and pharmacologic prophylaxis only when the surgeon clears it given the apixaban.
- Pulmonary and bowel care: incentive spirometry, coughing, stool softeners, and avoiding constipation.
- Monitoring: repeat CBC and renal function, watch for bleeding, and reassess neurologic status.
Most easily overlooked
- Delirium mistaken for baseline dementia.
- Constipation and urinary retention, which worsen agitation and may be attributed to dementia.
- Pressure injury on the sacrum and heels during long waits.
- Communication with the family, who may interpret the delay as neglect.
3. How will you answer the daughter's question and work with her as the health care agent?
Read the worked answer
Answering the question
- Explain the trade-off plainly: earlier surgery lowers the risks of immobility; waiting lowers the risk of serious bleeding, especially around the spinal anesthetic.
- State that this is a team decision being made today, and give a realistic timeframe for when she will hear the plan.
- Avoid promising a specific outcome or speaking for the surgeon.
Working with the agent
- Confirm the durable power of attorney document and that it covers health care decisions; document this.
- Confirm that Mrs. K's own preferences have been explored as far as her cognition allows, and include her in the conversation.
- Provide the information the agent needs to weigh the options, including the risks, benefits, and the alternative.
- Document the discussion, who participated, the decision, and the rationale; this supports consent and continuity across shifts.
