Hintergrund
Die Fotodokumentation von offenen Frakturen, Wunden, Dekubitalulzera, Tumoren oder Infektionen ist ein wichtiger Bestandteil der digitalen Patientenakte. Bisher ist unklar, welchen Stellenwert diese Fotodokumentation bei der Abrechnungsprüfung durch den Medizinischen Dienst der Krankenkassen (MDK) hat.
Fragestellung
Kann eine Smartphone-basierte Fotodokumentation die Verteidigung von erlösrelevanten Diagnosen und Prozeduren sowie der Verweildauer verbessern?
Material und Methoden
Ausstattung der Mitarbeiter mit digitalen Endgeräten (Smartphone/Tablet) in den Bereichen Notaufnahme, Schockraum, OP, Sprechstunden sowie auf den Stationen. Retrospektive Auswertung der Abrechnungsprüfung im Jahr 2019 und Identifikation aller Fallbesprechungen, in denen die Fotodokumentation eine Erlösveränderung bewirkt hat.
Ergebnisse
Von insgesamt 372 Fallbesprechungen half die Fotodokumentation in 27 Fällen (7,2 %) zur Bestätigung eines Operationen- und Prozedurenschlüssels (OPS) (n = 5; 1,3 %), einer Hauptdiagnose (n = 10; 2,7 %), einer Nebendiagnose (n = 3; 0,8 %) oder der Krankenhausverweildauer (n = 9; 2,4 %). Pro oben genanntem Fall mit Fotodokumentation ergab sich eine durchschnittliche Erlössteigerung von 2119 €. Inklusive Aufwandpauschale für die Verhandlungen wurde somit ein Gesamtbetrag von 65.328 € verteidigt.
Diskussion
Der Einsatz einer Smartphone-basierten Fotodokumentation kann die Qualität der Dokumentation verbessern und Erlöseinbußen bei der Abrechnungsprüfung verhindern. Die Implementierung digitaler Endgeräte mit entsprechender Software ist ein wichtiger Teil des digitalen Strukturwandels in Kliniken.
Objectives
Triangular fibrocartilage complex (TFCC) injuries frequently cause ulnar-sided wrist pain and can induce distal radioulnar joint instability. With its complex three-dimensional structure, diagnosis of TFCC lesions remains a challenging task even in MR arthrograms. The aim of this study was to assess the added diagnostic value of radial reformatting of isotropic 3D MRI datasets compared to standard planes after direct arthrography of the wrist.
Methods
Ninety-three patients underwent wrist MRI after fluoroscopy-guided multi-compartment arthrography. Two radiologists collectively analyzed two datasets of each MR arthrogram for TFCC injuries, with one set containing standard reconstructions of a 3D thin-slice sequence in axial, coronal and sagittal orientation, while the other set comprised an additional radial plane view with the rotating center positioned at the ulnar styloid. Surgical reports (whenever available) or radiological reports combined with clinical follow-up served as a standard of reference. In addition, diagnostic confidence and assessability of the central disc and ulnar-sided insertions were subjectively evaluated.
Results
Injuries of the articular disc, styloid and foveal ulnar attachment were present in 20 (23.7%), 10 (10.8%) and 9 (9.7%) patients. Additional radial planes increased diagnostic accuracy for lesions of the styloid (0.83 vs. 0.90; p = 0.016) and foveal (0.86 vs. 0.94; p = 0.039) insertion, whereas no improvement was identified for alterations of the central cartilage disc. Readers' confidence (p < 0.001) and assessability of the ulnar-sided insertions (p < 0.001) were superior with ancillary radial reformatting.
Conclusions
Access to the radial plane view of isotropic 3D sequences in MR arthrography improves diagnostic accuracy and confidence for ulnar-sided TFCC lesions.
Background
Traumatic separation of the pubic symphysis can destabilize the pelvis and require surgical fixation to reduce symphyseal gapping. The traditional approach involves open reduction and the implantation of a steel symphyseal plate (SP) on the pubic bone to hold the reposition. Despite its widespread use, SP-fixation is often associated with implant failure caused by screw loosening or breakage.
Methods
To address the need for a more reliable surgical intervention, we developed and tested two titanium cable-clamp implants. The cable served as tensioning device while the clamp secured the cable to the bone. The first implant design included a steel cable anterior to the pubic symphysis to simplify its placement outside the pelvis, and the second design included a cable encircling the pubic symphysis to stabilize the anterior pelvic ring. Using highly reproducible synthetic bone models and a limited number of cadaver specimens, we performed a comprehensive biomechanical study of implant stability and evaluated surgical feasibility.
Results
We were able to demonstrate that the cable-clamp implants provide stability equivalent to that of a traditional SP-fixation but without the same risks of implant failure. We also provide detailed ex vivo evaluations of the safety and feasibility of a trans-obturator surgical approach required for those kind of fixation.
Conclusion
We propose that the developed cable-clamp fixation devices may be of clinical value in treating pubic symphysis separation.
