Cost-effectiveness of short-term inpatient psychotherapy based on transactional analysis in patients with personality disorder
Short-term inpatient psychotherapy based on transactional analysis (STIP-TA) in patients with personality disorders (PD) has shown to be more effective than comparable other specialized psychotherapies (OP). The aim of this study was to assess whether the higher effectiveness of STIP-TA also results in a better cost-effectiveness. Patients treated with STIP-TA were matched with patients treated with OP by the propensity score. Healthcare costs and lost productivity costs were measured over 3 years and from the societal perspective. Cost-effectiveness was represented by costs per quality adjusted life years (QALYs). Uncertainty was assessed using bootstrapping. Mean 3-year costs were €59,834 for STIP-TA and €69,337 for OP, a difference of –€9,503, 95% CI [–32,561, 15,726]. QALYs were 2.29 for STIP-TA and 2.05 for OP, a difference of .24, 95% CI [.05, .44]. STI

Accurate perioperative flow measurement of the portal vein and hepatic and renal artery: A role for preoperative MRI?
AbstractBackgroundQuantification of abdominal blood flow is essential for a variety of gastrointestinal and hepatic topics such as liver transplantation or metabolic flux measurement, but those need to be performed during surgery. It is not clear whether Duplex Doppler Ultrasound during surgery or MRI before surgery is the tool to choose.ObjectiveTo examine whether preoperative evaluation of abdominal blood flow using MRI could prove to be a useful and reliable alternative for the perioperative sonographic approach.MethodsIn this study portal and renal venous flow and hepatic arterial flow were sequentially quantified by preoperative MRI, preoperative and perioperative Duplex Doppler Ultrasound (DDUS). 55 Patients scheduled for major abdominal surgery were studied and methods and settings were compared. Additionally, average patient population values were compared.ResultsMean (±SD) plasmaflow measured by perioperative DDUS, preoperative DDUS and MRI, respectively was 433±200/423±162/507±96ml/min (portal vein); 96±70/74±41/108±91ml/min (hepatic artery); 248±139/201±118/219±69ml/min (renal vein). No differences between the different settings of DDUS measurement were detected. Equality of mean was observed for all measurements. Bland Altman Plots showed widespread margins. Hepatic arterial flow measurements correlated with each other, but portal and renal venous flow correlations were absent.ConclusionsSurgery and method (DDUS vs. MRI) do not affect mean flow values. Individual comparison is restricted due to wide range in measurements.Since MRI proves to be more reliable with respect to inter-observer variability, we recommend using mean MRI results in experimental setups
