Monitoring Postoperative Patient-controlled Analgesia (PCA)

The introduction of Acute Pain Service (APS), 1985, specialized pain management could be offered to the inpatient care. An example of this is patient-controlled analgesia (PCA), which is a technique that is used mostly after surgery. A PCA pump is an electronic pump that is prepared with pain relief medicine, usually an opioid, which is administered either epidural or intravenously. PCA pumps are programmed with medical protocols. For prevent overdose, there are blocking times between possible bolus doses and a maximum dose per hour. In a Cochrane review from 2015, PCA have shown to be more beneficial for the patient especially when it comes to patient satisfaction, compared to conventional pain relief where nurses administer pain relief on request. The authors could also demonstrate that patients experience less pain and were more satisfied with patient-controlled analgesia. However, studies have showing limitations in the ease of practice of the PCA pumps, which indicates need for further development. Today the major part of the documentation in the Swedish healthcare is computerized. Using digital systems that communicate with each other should be seen as a matter of course. Instead, a human intermediator is commonly used where documentation is performed by pencil and paper. Due to the human factor that may affect the interpretation of the information the patient safety is placed at risk. The elimination of the human intermediator could lead to a safer transfer of information. There are already studies concerning computerized PCA pumps and wireless communication by medical devices, but only studies that are conducted outside of Europe and studies with the technical aspect in focus. Studies have shown that wireless communication by medical devices in the nursing setting can provide support for prioritization and increase the patient safety. However, the field of research lacks of knowledge when it comes to the patients' and nurses' experience of using PCA pumps
