https://www.selleckchem.com/products/picropodophyllin-ppp.html A goal of the International Prophylaxis Study Group (IPSG) is to provide an accurate instrument to measure MRI-based disease severity of haemophilic arthropathy at various time points, so that longitudinal changes in disease severity can be identified to support decisions on treatment management. We review and discuss in this paper the evaluative purpose of the IPSG MRI scale in relation to its development and validation processes so far. We also critically appraise the validity, reliability and responsiveness of using the IPSG MRI scale in different clinical and research settings, and whenever applicable, compare these clinimetric properties of the IPSG MRI scale with those of its precursors, the compatible additive and progressive MRI scales.What is known and objective A framework to evaluate the impact of clinical pharmacists in intensive care units (ICUs) in Chile has not yet been established. This study evaluates the cost avoidance and cost-benefit ratios of clinical pharmacist interventions in terms of treatment optimization in an adult ICU in southern Chile. Methods Clinical pharmacist interventions in a multidisciplinary adult ICU were assessed between January and December 2019. Only interventions suggested by pharmacists and accepted by the healthcare team were included in the analysis. Interventions were classified into six categories, and cost avoidance (in US dollars) was calculated for each category using a systematic validated approach. A cost-benefit ratio for clinical pharmacy services in the adult ICU was also calculated. Results and discussion Over the 12-month period, 505 interventions were performed in 169 patients, of whom 62% were male. Interventions were classified into the following six categories adverse drug event prevention (18%), which led to $87 882 in savings; resource utilization (ie change in medication route) (10%), which led to $50 525 in savings; individualization of pa
