Charlson comorbidity index

Charlson comorbidity index

(charl′sŏn)
[Mary E. Charlson, contemporary U.S. internist and epidemiologist]
A prognostic tool that estimates the likelihood that a person with particular illnesses will survive for a specified number of years. The index, which takes into account the patient's age and illnesses such as heart, lung, endocrine, kidney, or blood disorders, can also be used to estimate the resource utilization of patients with a variety of chronic diseases.

In univariable analysis, we have found the association of CRKP infection with Charlson comorbidity index, renal dysfunction, cardiovascular disease, ICU stay at the time of the positive culture, previous antibiotic use, use of [sz]-lactams and [sz]-lactamase inhibitor combinations, use of cephalosporins, carbapenems, fluoroquinolones, and antifungal agents, receipt of mechanical ventilation, indwelling of urethral catheter and gastric tube, hemodialysis, blood products' use, and Charlson comorbidity index [Table 1].
Their average Charlson comorbidity index was about 1.
This also controlled for length of stay, surgery and anesthesia, Charlson comorbidity index, critical illness, brain injury, and number of follow-up hospitalizations.
Beneficiaries with redacted claims also had significantly higher comorbidity burden, as measured by the Charlson comorbidity index, and significantly higher Medicare Parts A, B, and D spending.
Patients who presented with a Charlson Comorbidity Index (CCI) score of zero were admitted at a rate of 14.
The researchers collected additional data on the enrolled individuals regarding socioeconomic factors, urbanization, robustness of the local health care system, Charlson Comorbidity Index, adapted Diabetes Complications Severity Index, and other comorbidities and medications that could affect the outcomes of interest.
The following variables were studied: anthropometric variables (age, gender and body mass index), study of chronic comorbidities with the Charlson comorbidity index and podiatric examination.
Where: Age (continuous variable); CCI = Charlson Comorbidity Index (ordinal variable); GCS = Glasgow Coma Scale (continuous variable); AIS_HN = Head and Neck Abbreviated Injury Score (ordinal variable); and AIS_CHS = Chest Abbreviated Injury Score (ordinal variable).
For each patient, we calculated at admission the Charlson Comorbidity Index and the Simplified Acute Physiology Score (12).
We evaluated pre-operative comorbidities using the Charlson Comorbidity Index (CCI), a validated scale reflective of patients' comorbidity burden.
