Review the literature regarding the use of recombinant human erythropoietin (rHuEPO) to prevent red blood cell (RBC) transfusion in critically ill patients. ⋯ rHuEPO reduces the need for transfusions. A cost-effectiveness analysis of rHuEPO for this indication is needed. Defining an optimal dosage regimen, identifying patients most likely to respond to rHuEPO, and determining risk factors for ICU associated anaemia would provide information for appropriate rHuEPO utilization.

Review Comparative Study
Systematic review of the analgesic efficacy and tolerability of COX-2 inhibitors in post-operative pain control.
To evaluate the relative analgesic efficacy and tolerability of single-dose COX-2 inhibitors in post-operative pain management. ⋯ The analgesic efficacy and tolerability of single-dose COX-2 inhibitors were more effective than opioid-containing analgesics and similar to non-selective NSAIDs in post-operative pain management. Further studies are needed to examine the efficacy and tolerability of COX-2 inhibitors compared against active comparators over a longer duration to assess whether these short-term effects are mirrored by longer-term outcomes and to determine their ultimate risk-benefit profile.

Comparative Study
A HRG-based costing model for estimating pharmacy costs associated with surgical procedures.
The present study addresses pharmacy expenditure within a surgical directorate in a UK hospital. The aim of the study was to develop a health care resource group (HRG)-based costing model that can be used to forecast pharmacy expenditure based on surgical casemix. Such a model will be of benefit as an expenditure projection tool at a time when hospitals are developing accelerated operation programmes in an attempt to decrease hospital waiting times. ⋯ The estimated pharmaceutical cost for surgery items for February-April 2000 was 121,235 UK pounds. This figure was 3.92% over the actual pharmaceutical expenditure as determined from computer records. The February 2002 casemix varied considerably from that of 2000. However, the model estimated pharmaceutical cost of surgery performed in February 2002 (38,054 UK pounds) was again very similar to the computer logged expenditure (1.09% under the actual expenditure for that period) indicating the robustness of the HRG-based costing approach.

Therapeutic drug monitoring (TDM) of valproate (VAL) is important in the optimization of its therapy. The aim of the present work was to evaluate the ability of TDM using model-based, goal-oriented Bayesian adaptive control for help in planning, monitoring, and adjusting individualized VAL dosing regimens. USC*PACK software and routine TDM data were used to estimate population and individual pharmacokinetics of two commercially available VAL formulations in epileptic adult and pediatric patients on chronic VAL monotherapy. ⋯ These nonparametric expectation maximization (NPEM) population models thus provide a useful tool for planning an initial dosage regimen of VAL to achieve desired target peak and trough serum concentration goals, coupled with TDM soon thereafter, as a peak-trough pair of serum concentrations, and Bayesian fitting to individualize the PK model for each patient. The nonparametric PK parameter distributions in these NPEM population models also permit their use by the new method of 'multiple model' dosage design, which allows the target goals to be achieved specifically with maximum precision. Software for both types of Bayesian adaptive control is now available to employ these population models in clinical practice.
