RESUMO
The introduction of the G-DRG reimbursement system has greatly increased the pressure to provide cost effective treatment in German hospitals. Reimbursement based on diagnosis-related groups, which requires stratification of costs incurred is still not sufficiently discriminating the disease severity and severity in relation to the intensive costs in gastroenterology. In a combined retrospective and prospective study at a tertial referral centre we investigated whether this also applies for decompensated liver cirrhosis. In 2006, 64 retrospective cases (age 57 ± 12.9; â 69.2 %, â 29.8 %) with decompensated liver cirrhosis (ICD code K76.4) were evaluated for their length of hospitalisation, reimbursement as well as Child and MELD scores. In 2008, 74 cases with decompensated liver cirrhosis were treated in a prospective study according to a standardised and evidence-based clinical pathway (age 57 ± 12.2; 73 % â, â 27 %). Besides a trend in the reduction of length of hospital stay (retrospective: 13.6 ± 8.6, prospective 13.0 ± 7.2, p = 0.85) overall revenues from patients treated according to a evidence-based clinical pathway were lower than the calculated costs from the InEK matrix. Costs of medication as a percentage of reimbursement amount increased with increasing severity. In both years we could demonstrate an inverse correlation between daily reimbursement and disease severity which precluded cost coverage. For the cost-covering hospital treatment of patients with decompensated liver cirrhosis an adjustment of the DRG based on clinical severity scores such as Child-Pugh or MELD is warranted, if evidence-based treatment standards are to be kept.

Two extremely low birth weight (ELBW) infants developed characteristic signs of kernicterus at 4 and 8 months corrected age despite only moderate neonatal hyperbilirubinemia (peak serum bilirubin <10 g/dl) and phototherapy being applied according to current guidelines. Both girls were from twin pregnancies and had fetal complications (donor in a twin-twin transfusion syndrome and acardius-acranius malformation in the second twin, respectively), connatal anemia (initial hematocrit 30%), and mild acidosis after birth. They had been neurologically normal at discharge except for abnormal otoacustic emissions (OAE). At the time kernicterus was diagnosed, both infants were nearly deaf, showed severe psychomotor retardation with dystonic features and had marked bilateral hyperintensities in the globus pallidum on MRI. Based on these and similar cases from the literature, we question whether current phototherapy guidelines are appropriate for high-risk ELBW infants. Lower thresholds may be preferable, at least if additional risk factors, such as anemia, are present.

Functional and structural abnormalities in the thalamus as well as a generalized phospholipid membrane disorder have been implicated in the pathogenesis of schizophrenic psychosis. To determine whether thalamic neuronal abnormalities and altered membrane-associated metabolites can be detected in schizophrenic patients, we used in vivo proton magnetic resonance spectroscopy (1H-MRS) in 32 acutely-ill, medicated schizophrenic patients and 17 age-matched controls. Thalamic and white matter metabolite concentrations (myo-inositol (mI), choline-containing compounds (Cho), total creatine (Cr) and N-acetylaspartate (NAA)) were estimated and corrected for atrophy (CSF) and gray and white matter contributions (GM, WM) by use of image-based voxel segmentation. Thalamic NAA was significantly reduced in schizophrenic patients, whereas Cho and mI were significantly increased in the parietal white matter. White matter Cr was significantly elevated in patients and correlated positively with the brief psychiatric rating scores (BPRS). Regional metabolite levels were inversely associated with GM and WM content reaching significance for mI and Cr in the thalamus and Cho and NAA in the white matter. Reduced NAA in the left thalamus of schizophrenic patients confirms and extends previous spectroscopic data and agrees well with histologic and imaging findings of reduced neuronal density and volume. Elevated Cho in line with 31P-MRS studies suggests increased myelin degradation thus further supporting a generalized membrane disorder in schizophrenic patients. In addition, we demonstrate the need to correct metabolite concentrations for regional tissue composition in studies employing patients with altered brain morphology.
