Reference id: (b)(4).The combidiagnost is a remote-controlled system, which supports general radiography and fluoroscopy imaging.The images of fluoroscopy exams are displayed on a separate so called rf viewer.From there they can be flagged for image manipulation, export, etc.Philips received a complaint on combidiagnost r90 indicating that table up down movement is not straight intermittently and might cause harm to the patient.There was no actual harm reported to the patient or user.Based on good faith efforts with the field service engineer, service manager, and clinical application specialist, it was confirmed that the doctor followed the workflow described below during the procedure.The doctor was performing peripherally inserted central catheter (picc) and percutaneous transhepatic biliary drainage (ptbd) procedures.In this workflow, the doctor first inserts the needle into the patient¿s peripheral veins or abdominal wall and then raises the table to the desired operating height to locate and adjust the needle position.During this process, the irregular upward table movement made it difficult for the doctor to stabilize the needle, which could potentially cause patient injury.However, it was confirmed that no patient harm occurred.The steps followed by the doctor are not defined.If the table height is set before needle insertion, any subsequent table movement does not pose a risk.In this case, the doctor inserted the needle while simultaneously raising the table, which is not a recommended.To prevent recurrence of such scenarios, the r&d team has provided an improved workflow recommendation to guide correct system usage.Reproduction of the reported behavior: the behavior can be reproduced as follows: set the table to its lowest position.Raise the table upward.A jerky movement may be observed during upward motion.Steps followed by the doctor (as reported): the doctor described the daily workflow for picc/ptbd procedures as: the patient is moved onto the examination table, assisted by the nurse and radiographer (including preparation tasks such as ecg).During the examination, the doctor adjusts the table height based on personal comfort.After the examination, the table is lowered to help the patient return to the hospital bed.The customer is following a non-standard workflow, inserting the needle first and adjusting the table height afterward.The recommended workflow, followed by most customers, is to adjust the table height first and then insert the needle.Since the deviation from the recommended workflow triggered the scenario, this is considered an improvement opportunity rather than a product malfunction.Solution: the clinical application specialist advised the customer to follow the usual workflow to avoid recurrence of this scenario.Based on all available evidence, the issue resulted that customer¿s current workflow is slightly different from what is followed by other customers.
