Prozessoptimierung im „kranken Haus“

Starting January 1st 2004 the German diagnosis-related group (DRG) system was established for in-patient cases. Consequently, the detection and realization of cost-saving potentials are becoming more and more important. For a successful future, efficient allocation of resources is essential. Economically, anaesthesia-related time delays during perioperative work-flow should be minimized. Since numerous entities contribute to perioperative care, it is extremely complex to analyze and optimize this process flow. In this publication single steps leading to an optimized perioperative process flow will be presented: documentation of predefined time points, calculation of relevant time intervals and analysis of key numbers for complex settings. Single steps of the given process analysis will be demonstrated using data from surgical patients at the University Hospital Schleswig-Holstein, Campus Kiel. The attached data collection sheets can be used by interested hospital departments and are meant to serve as a template for further process analyses. Based on the shown analysis, an example will be given to develop an optimized work-flow as a standard operating procedure (SOP). The implementation of the SOP module in an interdisciplinary clinical pathway (CP), which defines efficient medical care from admission to discharge, is mainly responsible for decreased process costs but increased quality of care.

Aminoglycoside-associated hypomagnesaemia in children with cystic fibrosis

Hypomagnesaemia in children with cystic fibrosis (CF) is under-recognized. We report a child with CF who developed significant hypomagnesaemia following intravenous (i.v.) treatment with aminoglycosides for exacerbations of Pseudomonas aeruginosa infection. Three additional cases have also been observed. Investigations in two patients have revealed excessive renal loss of magnesium. It is postulated that renal tubular damage secondary to the cumulative effects of repeated courses of aminoglycosides resulted in hypomagnesaemia, and we suggest screening for this problem by monitoring serum magnesium regularly in all patients with CF receiving multiple courses of aminoglycosides.     

The double puncture: an effective percutaneous technique for removing complex, multiple renal calculi

Percutaneous nephrostolithotomy, which can require a double puncture, is presently the method of choice in our institution for the removal of renal stones. Patients that underwent this procedure were evaluated to identify the possible reasons for the double puncture. Of 200 patients evaluated, 14 needed a second tract. The three variables that determined whether a second puncture was needed, in order of importance, were number and size of the stones, with second tracts needed in patients with multiple stones and staghorn calculi; anatomical variations of the renal collecting system itself, with bifid systems the most significant anatomic variation; and the dexterity of the radiologist in performing the puncture and the ability of the urologist to extract the stone. Second tracts were needed more frequently in patients who presented with stones in both the lower and middle poles of the collecting systems.
