Evaluation of Quality of Care in a Large Saudi Hemodialysis Center (Prince Salman Center For Kidney Diseases, Riyadh, KSA)

Figures & data

Table 1. Modified Charlson comorbidity index, the comorbidity points.

Comorbidity points
1 point each for coronary artery disease, congestive heart failure, peripheral vascular disease, cerebrovascular disease, dementia, chronic pulmonary disease, connective tissue disorder, peptic ulcer disease, mild liver disease, diabetes. 1 point for every decade over 40.
2 points each for hemiplegia, moderate-to-severe renal disease (including being on dialysis), diabetes with end-organ damage, cancer (including leukemia or lymphoma)
3 points for moderate-to-severe liver disease
6 points each for metastatic solid tumor or AIDS
