Pilot study: Bone-anchored Port for hemodialysis

Bone-anchored hearing aids seem to be more resistant against infections as compared with (non-) tunneled catheters for hemodialysis. Patients with catheter-related bloodstream infections suffer from morbidity and mortality. The new designed bone-anchored port (BAP) connected to a conventional hemodialysis catheter is currently under evaluation for safety and functionality.
Starting in 2010, physicians and engineers have developed this bone anchored port which was implanted in April 2016 for the first time in man. Aim of this pilot study is to check the implantation procedure, but also with a prospective follow-up to get experience with handling of the device during dialysis and to observe the quality of dialyses
Until October 1st, 2018 the bone-anchored port was implanted into 6 patients. During the first 30 days one patient needed a skin flap to cover a skin defect. Dialysis started on average on day 7 (range 1-15). By 30.11.2018 we oversee 1944 patient days (Ø 324, days, range 45-479). One patient died unrelated to the device after 14 month. A problem with the inner valve resulted in a technical change after the first patient.
An interdisciplinary team is needed to implant the device, which can be implanted in a safe manner and is appreciated by patients and nurses due to its simple handling. An intensive education program is mandatory in order to spread this method and to get more data concerning functionality and performance. In the future the easy and safe handling of this system may be helpful in patients with a portable dialysis device.
