[Cross sectional study of structural quality of German intensive care units. A reevaluation of the DIVI register]. / Querschnittstudie der Strukturqualität deutscher Intensivstationen. Eine Reevaluation der Strukturdaten des DIVI-Registers.

BACKGROUND: Effectiveness of intensive care treatment is essential to cope with increasing costs. The German national register of intensive care established by the German Interdisciplinary Association for Intensive Care Medicine (DIVI) contains basic data on the structure of intensive care units in Germany. A repeat analysis of data of the DIVI register within 8 years provides information for the development of intensive care units under different economic circumstances. METHODS: The recent data on the structure of intensive care units were obtained in 2008 and compared with the primary multicenter study from 2000. The hospitals selected were a representative sample for the whole of Germany. Data on the status of the hospital, staff and technical facilities, foundation of the hospital and the statistics of mechanically ventilated patients were analyzed. RESULTS: The technical facilities and the number of staff have improved from 2000 to 2008. A smaller availability of diagnostic procedures and staff remain in hospitals for basic treatment outside normal working hours. The average utilization of intensive care unit beds was not altered. The existence of intermediate care units did not significantly change the proportion of patients with artificial ventilation or ventilation times. The number of beds in intensive care units was unchanged as was the average number of beds in units and the number of patients treated. A relevant number of beds of intensive care units shifted towards hospitals with private foundation without changes in the overall numbers. The structure of the hospitals was comparable at both time points. CONCLUSIONS: The introduction of intermediate care units did not alter ventilation parameters of patients in 2008 compared with 2000. There is no obvious medical reason for the shift of intensive care beds towards private hospitals. The number of staff and patients varied considerably between the intensive care units. The average number of patients treated per bed was not different between the periods or between hospitals with different structures. Overall availability of medical staff and diagnostic procedures increased during the study period. An increase of availability of fully trained medical staff in intensive care medicine is desirable to increase the quality of treatment.

[Degloving injuries of the lower limb]. / Die Décollementverletzung im Bereich der unteren Extremität.

Although seldom dangerous to life, these degloving injuries are all potentially infected and, unless treated as acute surgical emergencies, inevitably lead to serious complications. Diagnostic is done according to a standardized protocol, which eventually must be integrated in the standard polytrauma management. Multidisciplinary (orthopedic surgery, plastic surgery, dermatology, physiotherapy) defect management is of utmost importance and requires an "integrated therapy concept". The success or failure of primary treatment of degloving injuries is determined by an adequate primary care including debridement, osteosynthesis (if necessary) and soft tissue and skin management. If the skin is no more vascularised, it should be thinned out and refixed as a full thickness skin graft at the day of injury. Still vascularised skin flaps should be replaced and fixed with few stitches. A second look operation 24 to 72 hours later should be planned. Secondary surgery is necessary in almost every patient in order to improve the functional or aesthetic result. Adjuvant procedures such as physiotherapy, standardized scar treatment, orthesis, orthopedic shoes, etc. may be useful at any time of treatment.

[Interdisciplinary quality management in the treatment of severely injured patients. Validation of a QM system for the diagnostic and therapeutic process in early clinical management]. / Interdisziplinäres Qualitätsmanagement in der Behandlung schwerverletzter Patienten. Validierung eines QM-Systems für den diagnostischen und therapeutischen Ablauf der frühklinischen Versorgung.

A multidisciplinary quality management system (QMS) for the early treatment of severely injured patients was validated in a trauma center in Germany. In the presented prospective study a QMS developed at another trauma center was implemented at the department of trauma surgery of the University of Essen for the presented study. The essential elements of the QMS were the establishment of (1) an adequate protocol for documentation, (2) 20 criteria for the assessment of treatment quality, (3) regular statistical analysis of treatment quality and (4) a quality circle comprising all medical specialties for data discussion. From 5/98-9/99 a cohort of 447 patients with an average injury severity score (ISS) of 22 +/- 17 was treated in the emergency department. The impact of the QMS was assessed in 4 periods (1: 5/1998-8/1998; 2: 9-12/1998; 3: 1-4/1999; 4: 5-8/1999). The quality circle met 8 times. For the improvement of the process 16 long-term changes were introduced. In 60% (n = 12) of the 20 assessment criteria significant improvements were detected. In diagnostics there were significant reductions of the time needed for basic radiological and sonographic check-up (from 24 +/- 12 min in the first to 14 +/- 8 min in the last period) and of the duration until performance of a cranial computed tomography in severe traumatic brain injury (sTBI; from 45 +/- 22 to 28 +/- 8 min). The rate of delayed diagnoses remained low (4% in the first, 5% in the last period). Further positive changes were the time savings in transfusion (from 35 +/- 20 to 20 +/- 4 min) and emergency operations (from 67 +/- 20 to 48 +/- 4 min) in hemorrhagic shock as well as for craniotomies (77 +/- 41 to 54 +/- 19 min) in sTBI. Apart from the significant time reductions other improvements were found. Overall mortality was diminished from 17% in the first to 10% in the last observation period. In conclusion the study revealed that the quality of the early therapy of severely injured patients was significantly improved by implementation of a multidisciplinary quality management system especially with respect to treatment efficiency.
