Structural Equation Model (SEM) of Stroke Mortality in Spanish Inpatient Hospital Settings: The Role of Individual and Contextual Factors

Abstract: Introduction: Traditionally, predictive models of in-hospital mortality in ischemic stroke have focused on individual patient variables, to the neglect of in-hospital contextual variables. In addition, frequently used scores are betters predictors of risk of sequelae than mortality, and, to date, the use of structural equations in elaborating such measures has only been anecdotal. Aims: The aim of this paper was to analyze the joint predictive weight of the following: (1) ind… Show more

“…23 It has been widely used to analyse complex associations in different areas, including medicine, particularly to explore aetiology and identify best treatments. 24,25 Our findings suggest that COVID-19 deaths are mainly associated with lower GCS scores. In the structural equation modelling, Conversely, low tolerance to hypoxia could also lead to a shorter expectation of survival time.…”

“…However, the HL test is based on a chi-square test, which with such large sample sizes is usually non-significant. To avoid this limitation, we applied the Pearson χ2 test, implemented by Stata software [ 38 ], which confirmed the absence of significant differences in our calibration analysis, as we hoped.…”

“…Moreover, some studies examined only non-reperfused ischaemic strokes while others addressed haemorrhagic strokes and ICU treatment in separate analyses [ 15 ]. It is important to note that stroke units make greater use of specialist procedures and therapeutic effort than is the case with patients managed conservatively, as is the case of those examined in our study [ 38 ]. Only Aylin et al [ 39 ] used data from a database comparable to the Spanish MDBS (in their case, from the British NHS) but this analysis was applied to non-cerebral vascular pathologies.…”

“…AMOS (v. 23.0) for Windows was used for structural validity analysis and for constructing the structural prediction model—specifically, in verification of the structural linear prediction hypothesis (path analysis). We attempted to replicate the same analysis scheme as in a previous paper (de la Fuente et al 2019 [ 12 ], with a different sample and problem. In model 1, we tested the relationships of the 17 variables, without constructing second-level latent variables.…”
