Is patient-controlled analgesia controlled by the patient?

Using patient-controlled analgesia (PCA) after surgery, a patient can obtain pain-relieving injections of morphine without the direct involvement of a nurse or doctor. The present study was a response to the conventional view that patients value PCA because of the control which it affords them over their own treatment. Twenty-six patients underwent semi-structured interviews postoperatively, shortly after discontinuation of PCA. Responses were examined qualitatively to identify recurring themes in patientsʹ experience of PCA. Negative as well as positive evaluation was found. PCA was only rarely described as a way of gaining control over analgesia and, in general, this was not valued. Instead, PCA was valued as a way to avoid the difficulty of disclosing pain or securing pain relief within the usual nurse-patient relationship. In turn, PCA strained the nurse-patient relationship where it impeded either the patientʹs or the nurseʹs wish for the nurse to take responsibility for pain relief. The results showed that the professionally and theoretically constructed concept of PCA as a method of self-control over pain is inconsistent with patientsʹ experience of it.
