[Implementation of diagnosis related groups methodology in a university hospital].
Background The Diagnosis Related Groups (DRG) constitute a method of classifying hospital discharges. Aim To report its development and implementation in a Chilean University Hospital and global results of 10 years Material and Methods We included 231,600 discharges from 2007 to 2016. In the development we considered the physical plant, clinical record flow, progressively incorporated human resources and computer equipment for coding and analysis to obtain results. ⋯ They occupied 40% of bed days. Nine percent had a grade 3 severity with high median hospital stay and accounting for 31.5% of bed days. Conclusions DRG methodology is a valuable information tool for decision making and result assessment in hospital management.

Comparative Study[Association between cytochrome p4502c9 polymorphisms and losartan dosing in hypertensive patients].
Background Losartan is widely used in many clinicals settings. Its dosage is related to the genetic characteristics of CYP2C9 enzymatic activity, which metabolizes losartan to its active form E-3174, responsible for the antihypertensive effect. Aims To identify the frequency of allelic variants CYP2C9*2 and CYP2C9*3 in hypertensive patients and to compare genotypes with a healthy Chilean population. ⋯ The same tendency was observed with the need to use losartan twice a day, obtaining an OR of 5.88 (CI 0.54 -62.14). Conclusions There could be a relationship between the presence of CYP2C9 polymorphisms and the pathogenesis of hypertension. The presence of CYP2C9*3 is associated with the need for higher doses of losartan, possibly due to a decrease in the conversion of losartan to E-3174.
