PTA Asked to Re-Evaluate a Post-Operative Patient with Calf Pain
At a busy outpatient clinic, Dana, a PT, has 18 patients scheduled and is covering a satellite clinic 25 minutes away for the afternoon. She evaluated Mrs. Nguyen, a 68-year-old 10 days after total knee arthroplasty, yesterday and set a plan of care. Today she delegates the visit to Luis, a licensed PTA. During the visit Mrs. Nguyen reports new right calf pain, 2 cm circumferential swelling compared with yesterday, and shortness of breath on standing. Luis calls Dana and asks whether he can increase the resistance band, add single-leg balance, and 'just complete the re-evaluation' because the patient is due for a progress note. Dana can hear the clinic front desk asking Luis to hurry. The clinic has no written supervision policy beyond 'PT available by phone.'
1. What may Luis do and not do under Oregon law and the delegation relationship?
Read the worked answer
Luis may carry out delegated interventions within the established plan of care and collect ongoing data, such as measuring knee range of motion, observing response to exercise, and reporting findings to Dana. He may not perform the initial evaluation or a re-evaluation that requires clinical decision-making, interpret new symptoms, alter the plan of care, or add resistance and balance progressions that Dana has not delegated. A PTA practices under the PT's supervision, and the PT remains responsible for the plan of care and for determining whether the patient's condition has changed. The new calf pain, swelling, and shortness of breath are not routine post-operative complaints; they are red flags for deep vein thrombosis or pulmonary embolism. Luis should stop the session, keep Mrs. Nguyen at rest, and contact Dana immediately. He should not 'just complete the re-evaluation' or advance exercises.
2. What must Dana do about the calf pain and shortness of breath, and what does this mean for supervision?
Read the worked answer
Dana must personally direct the response rather than delegate the decision. She should tell Luis to stop the session, check vital signs if safe, and arrange same-day medical evaluation by contacting the surgeon or emergency services if shortness of breath is significant. She should document the call, the advice given, the patient's status, and the transfer plan. The fact that Dana is 25 minutes away matters: 'available by phone' may not satisfy the supervision needs of a PTA treating a patient with a new red flag. Dana should ensure a covering PT is on site or direct Luis to stop and transfer care. She should not ask Luis to independently decide whether the symptoms are benign. The clinic should also adopt a written supervision policy that addresses red flags, on-site coverage, and escalation.
3. How should this visit be documented, including Luis's role and Dana's supervision?
Read the worked answer
Luis should document the interventions he provided, the objective data he collected, the patient's reports of calf pain and shortness of breath, the time he stopped the session, and the fact that he contacted Dana. Dana should document her supervisory decision, the advice she gave, the medical referral, and any communication with the surgeon or emergency department. The record should identify who performed each service and who supervised. It should not imply that Luis performed a re-evaluation if he did not. If Dana later performs the re-evaluation, she should document it personally. The documentation should also reflect that the patient was informed to seek urgent care if symptoms worsened. Clear records protect the patient and demonstrate that delegation stayed within the PTA's role.
