[Developing a recommendation for handling risks through digital transformation in patient care]. / Entwicklung einer Handlungsempfehlung zum Umgang mit Risiken in der Patientenversorgung durch Entwicklungen im Rahmen der digitalen Transformation.

Digital transformation in healthcare presents enormous challenges as it partially redefines care processes and interaction between patients and doctors. In order to seize opportunities to improve patient care as well as patient safety by using digital innovations, arising patient safety risks due to these changes have to be considered and addressed. The German Coalition for Patient Safety, the Austrian Network for Patient Safety and the Swiss Foundation for Patient Safety decided to develop a recommendation for members of all professional groups in healthcare to sensitize for arising risks, inform about cause-effect relationships and to empower professionals to perform an individual risk-benefit-assessment for existing and upcoming digital innovations. In May 2017 the German Coalition on Patient Safety implemented its working group Digitization and Patient Safety with its subgroup Digitization and Risk Management. Based on open brainstorming of experts followed by a nominal group technique process the most relevant risks for patient safety arising from digitization were identified and assessed by using a modified scenario analysis. After internal consultation of all members of the German Coalition for Patient Safety and all executive boards of participation associations, the recommendation was published at the annual meeting of the German Coalition for Patient Safety in May 2018. We identified six core risks that were assessed by modified scenario technique: insufficient protection of the IT system from external attacks, insufficient protection of the IT system from unauthorized access, non-availability of IT system or patient data, handing over data to external service providers, unsafe embedding of medical devices in IT systems and insufficient digital literacy of healthcare professionals. In addition, we developed a checklist for the self-assessment of risks arising from implementing digital innovation, using risk criteria according to ONR 49002-2:2014, and provided key questions for decision makers. On the basis of the approach described a multiprofessional and intersectoral recommendation for clinical core risks associated with digitization in healthcare was developed within a 12-month period. The dissemination of this recommendation in German language can be regarded as very successful since the German Coalition for Patient Safety received more than 22,000 requests for paper copies, and 1,200 downloads of this open-access publication have been registered. An English version of this recommendation will soon be available.

Polyetheretherketone-a suitable material for fixed dental prostheses?

OBJECTIVES: To study the surface properties of polyetheretherketone (PEEK) and its bond strength with two veneering resins after different conditioning methods as well as fracture load of PEEK three-unit fixed dental prostheses (FDPs). METHODS: Two hundred and twenty five PEEK specimens were fabricated and divided into five groups: no treatment (A), etching with 98% sulfuric acid for 1 min (B), air-abrasion for 10 s with either 50 or 110 µm alumina (C and D, respectively), and silica coating using the Rocatec System (E). On 15 specimens of each conditioning method, contact angle and surface roughness were determined. The remaining 150 specimens of each conditioning method were divided into two groups for the veneering procedure with the composites Gradia (GC Europe) and Sinfony (3M ESPE). Shear bond strength (SBS) was measured and failure types were assessed. In addition, 15 FDPs were milled and the fracture load was tested. Data were analyzed using descriptive statistics, one-way ANOVA (Scheffé test), two sample Student's t-test, and Weibull statistics (p < 0.05). RESULTS: Silica-coated PEEK surfaces showed the highest wettability. The highest roughness and lowest contact angles were observed for 110 µm air-abraded and silica-coated PEEK surfaces. The highest SBS values were, however, achieved in the acid-etched group. PEEK three-unit FDPs showed a mean fracture load of 1383 N with a plastic deformation starting approximately at 1200 N. CONCLUSIONS: Acid etching should be applied when PEEK is used as substructure material and composite veneering material is applied. In this combination, PEEK might be a suitable material for FDPs, especially in load-bearing areas.
