TBI can be classified as mild, moderate and severe based on severity of the injury.
Additionally, given that many chronic conditions have heterogeneous manifestations with a variable course and unpredictable episodes of exacerbation, the analysis can be carried out under several person stratification schemes based on severity of disease, various demographic attributes, and socio-economic conditions.
Each of these regimens falls back on the classification of IAI based on severity of disease expression (mild, moderate, severe), anatomical disruption, and community-acquired or early-onset healthcare-associated origin versus late-onset healthcare-associated origin and/or recent antimicrobial exposure (2 4 days of therapy) [ table II].
Several studies did not stratify patients based on severity of illness (for example, Child Pugh score and APACHE [Acute Physiology and Chronic Health Evaluation] score) and hence it is difficult to assess patient matching or the impact of underlying disease on patient mortality with or without treatment.
20 Additional benefits of modelling with only one health state is that it offers increased flexibility to incorporate estimates of benefit (that is, relative risk for end stage renal disease and death) as reported in clinical trials, compared with models that use several distinct stages of chronic kidney disease based on severity of disease.
Planned subgroup analyses 13 were based on severity of the woman's pre-eclampsia at trial entry (severe, moderate or mild), whether randomised before or after delivery and perinatal mortality (PNM) in the country (high, medium or low).
Seriousness scales are based on severity ratings of behaviors, usually developed by experts in the field.
Thus, the differences across these cases were based primarily on severity of illness (predicted mortality).
Should society punish people based on the severity of the allegations against them, or only on the severity of the crimes for which they are convicted?
It allows ambulance crews to make rational decisions about the choice of hospital, based on the severity of injuries [4, 5].
