Technician Delegation, Warfarin CPA, and an INR of 5.2
At a community pharmacy with one pharmacist on duty, two registered pharmacy technicians, and one cashier, the queue has 14 prescriptions. The pharmacy has a written collaborative practice agreement with a local primary care group for warfarin management. A technician answers the phone and receives an INR result of 5.2 for a 68-year-old patient who also reports gum bleeding and bruising. The technician says, 'I'll tell her to hold tonight's dose and call the clinic.' Meanwhile, a second technician asks to perform the final verification on a refill of metformin because the pharmacist is counseling a patient on a new inhaler. The cashier asks whether she can explain the difference between omeprazole OTC and prescription omeprazole to a waiting patient. The pharmacist also notices the warfarin patient's chart has no documentation of the last two INR calls.
1. Which of the technician's proposed actions may be delegated under Maryland law and the CPA, and which must the pharmacist perform personally? Explain.

The technician may receive the INR value and relay it to the pharmacist, and may gather the patient's symptoms, but may not independently tell the patient to hold warfarin. That is clinical assessment and advice. Under the CPA, only tasks within the written agreement and within the technician's training may be delegated; the pharmacist retains the judgment. Final verification is nondelegable: the pharmacist must perform the prospective DUR and final check on the metformin, even if the technician is experienced. The cashier may not counsel. Counseling on omeprazole and on the inhaler must be done by the pharmacist or by a pharmacy technician only where Maryland law allows technician counseling-generally not for clinical advice; the pharmacist should counsel. The pharmacist should also ensure that any technician involved in the warfarin workflow is competent and that the CPA defines the technician's role. If the pharmacist is too busy to safely supervise, the correct action is to slow the workflow or obtain help, not to delegate nondelegable acts.
2. What should the pharmacist do immediately for the patient with INR 5.2 and bleeding, and how should the CPA be used?
Read the worked answer
Treat INR 5.2 with gum bleeding and bruising as a potentially serious bleeding event. First assess for major bleeding-melena, hematuria, severe headache, hypotension, or uncontrolled bleeding-and if present, send the patient to the emergency department immediately. If the bleeding is minor, follow the CPA: usually hold one or more warfarin doses, recheck INR within 24–48 hours, and consider vitamin K only as the protocol directs. The pharmacist-not the technician-must speak with the patient, review all medications (including the new antibiotic or OTC product that may have interacted), and notify the prescriber. Document the INR, symptoms, dose hold, instructions, prescriber contact, and follow-up plan. If the CPA does not cover bleeding or the prescriber cannot be reached, escalate. Do not let the technician 'just tell her to hold' without pharmacist assessment.
3. What documentation and quality-improvement follow-up are required after the two missed INR calls?
Read the worked answer
Document each INR call, the date and time, the result, the pharmacist's assessment, the dose change, the patient instructions, and the prescriber notification. The missing documentation for two prior calls is a recordkeeping and quality problem. Open an incident report or QI referral, review the workflow for missed calls, assign responsibility for checking voicemail and faxed results, and audit the next month's INR documentation. Use a nonpunitive, system-focused review rather than blaming one technician. If the patient was harmed or a reportable event occurred, follow hospital or corporate policy and Maryland reporting requirements; not every near miss goes to the Board. Retain records for the period required by Maryland law and make them available to the Board on request.
