Risicoprofiel infusietechnologie te hanteren als kwaliteitsdocument van de Nederlandse Vereniging voor Klinische Fysica en als basisdocument voor het QMT® (Quality for Medical Technology) systeem

Borging van kwaliteit en veiligheid rond medische technologie is binnen zorginstellingen, en ook in toenemende mate daarbuiten, een belangrijk punt van aandacht. Basis hierbij is een integraal managementsysteem voor borging van kwaliteit en vailigheid, dat rekening houdt met de risico's per toegepaste technologie en in directe relatie met de gebruikssituatie

Equipment-related incidents in the operating room: an analysis of occurrence, underlying causes and consequences for the clinical process

Background: Equipment-related incidents in the operating room (OR) can affect quality of care. In this study, the authors determined the occurrence and effects on the care process in a large teaching hospital. - \ud \ud Methods: During a 4-week period, OR nurses reported equipment-related incidents during surgery procedures in both locations of the hospital. The incidents were reported using a separate form for each incident. A structured analysis (PRISMA) was used to analyse incidents that resulted in serious delays (>15 min). - \ud \ud Results: Forms were returned for 911 out of 1580 surgeries (57.7%). In total, 148 incidents were registered, relating to a total of 29 h and 45 min of extra work. In addition, 12 h and 9 min of operational delay was registered. Most incidents involved instruments (46%) or medical devices (28%). 68% occurred during surgery and 32% during the preparation phase. No direct physical harm was reported, although indirect harm, like longer anaesthesia, did occur and can be defined as an adverse event. 10% of the incidents led to a delay of over 15 min. For these incidents, ‘management decisions’ (eg, inventory capacity, planning procedure) was the most encountered root cause. Only six out of the 148 incidents found corresponded with the blame-free reporting database. - \ud \ud Conclusions: Equipment-related incidents occurred frequently in the involved hospital sites (up to 15.9%) and resulted in some extra work and additional minutes of delay per event. Management decisions have considerable influence on the occurrence of equipment-related incidents. There was serious under-reporting of incidents

Microwave spectroscopy of interacting Andreev spins

Andreev bound states are fermionic states localized in weak links between superconductors which can be occupied with spinful quasiparticles. Microwave experiments using superconducting circuits with InAs/Al nanowire Josephson junctions have recently enabled probing and coherent manipulation of Andreev states but have remained limited to zero or small magnetic fields. Here, we use a flux-tunable superconducting circuit compatible in magnetic fields up to 1T to perform spectroscopy of spin-polarized Andreev states up to ∼250mT, beyond which the spectrum becomes gapless. We identify singlet and triplet states of two quasiparticles occupying different Andreev states through their dispersion in magnetic field. These states are split by exchange interaction and couple via spin-orbit coupling, analogously to two-electron states in quantum dots. We also show that the magnetic field allows to drive a direct spin-flip transition of a single quasiparticle trapped in the junction. Finally, we measure a gate- and field-dependent anomalous phase shift of the Andreev spectrum, of magnitude up to ∼0.7π. Our observations demonstrate alternative ways to manipulate Andreev states in a magnetic field and reveal spin-polarized triplet states that carry supercurrent.QRD/Kouwenhoven LabQRD/Goswami LabQN/Kouwenhoven LabAndersen La
