Tools for the Assessment of Comorbidity Burden in Rheumatoid Arthritis

Abstract: IntroductionComorbidities influence the prognosis, clinical outcomes, disease activity, and treatment response in rheumatoid arthritis (RA). RA patients have a high-comorbidity burden necessitating their study. Comorbidity indices are used to measure comorbidities and to study their impacts on different outcomes. A large number of such indices are used in clinical research. Some indices have been specifically developed in RA patients.AimThis review aims to provide an overview of generic and specific comorbidit… Show more

“…This comparison arm however is difficult to find, since patients recruited at primary care clinics may be offered higher screening than the general population, just for the reason of being medically followed. Finally, we didn't use common validated comorbidity indices, because they are usually validated only in one type of RMD, mostly RA 62,63 . Instead, we preferred using the EULAR points to consider as they cover all RMD simultaneously.…”

“…Additionally, a Charlson co-morbidity index (CCI) was also available. The CCI reflects 19 conditions related to the potential for mortality and morbidity [ 24 ]. Finally, a variable was also included to indicate whether the patient was new to the Rheumatology Department at the time of the study visit or whether they were an established patient.…”

“…The CCI allows for adjustment of baseline comorbidity between groups, and is a widely used comorbidity index in studies that use administrative health data. 25 The higher the score, the more likely the predicted outcome will result in mortality or higher resource use. 26,27 MS characteristics included severity of MS, symptoms, fatigue, and perceived cognitive impairment.…”
