Abstract

Background: Using APACHE II system can be a guide for therapists working in ICU to objective assess patients (with the estimation of their chance of recovery). The aim study was to compare the mortality estimation by using the systems of APACHE II GCS and 4score. Methods: This cross sectional - prospective study comprised 167 adult patients, hospitalized in ICU of selected hospitals in a one-year period. Their disease severity scores were measured with disease severity scoring system (APACHE II GCS and 4score). Their chances of recovery were estimated and compared. The survival or death of the patients was recorded. Data were analyzed by SPSS 16.0 and MEDCALCK/9.2.2, by using nonparametric statistical tests and survival analysis. Results: 92 patients survived and 75 died. In the survived group, the APACHE II GCS score was (14.75 ± 6.56) and 4score was (14.83 ± 6.831) and in the dead group the APACHE II GCS score was (21.26 ± 6.02) and 4score was (21.90 ± 6.02). The Mann-Whitney statistical test showed that the estimates of death and actual death rate, the relationship between the estimation of the APACHE II GCS with the actual death rate was obtained z = - 5.816, P < 0.001 · and 4score scale was obtained z = - 5.983, P < 0.001, respectively. Conclusion: Due to the small, but significant, changes in the results, the researcher suggests that in estimating the chances of death, the APACHE II 4score scale scoring system can be used in order to have the least possible error. © 2018 Medknow.
