An Easy to Use Rheumatoid Arthritis DAS28 Calculator (DAS 28) that also allows you to record swollen and tender joints and to print out the mannequin and store it in the Patient's file or chart

The Disease Activity Score-28 for Rheumatoid Arthritis with ESR (DAS28-ESR) describes severity of rheumatoid arthritis using clinical and laboratory data.

DAS44包括4项核心指标：关节指数（RAI）、关节肿胀数（SJC）、急性期反应物水平（ESR或CRP）、100mm疼痛视觉模拟标尺（VAS100mm）。 随后在使用DAS44评定标准的过程中发现关节检查时间较长，且发现计算指定的28个关节（表2）的肿胀数和压痛数与DAS44同样有效和可靠，于是提出了简化的DAS28评分法。 以下是DAS28计算公式及评分标准：

DAS stands for Disease Activity Score. It assesses your joints, blood test results – C-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) – and also your own view of how you have been feeling over the past week. The reason it’s called DAS 28 is because it assesses 28 specific joints for tenderness and/or swelling.

This DAS28 ESR for rheumatoid arthritis calculator determines the RA disease activity score based on the erythrocyte segmentation rate.

The DAS28 (Disease Activity Score in 28 joints) is an amalgamation of the number of tender and swollen joints, the erythrocyte sedimentation rate, and a visual analogue score of the patient's overall health. Although DAS28 has limitations, and cannot replace specialist assessment, it provides a measurement of disease activity that can be ...

The DAS provides a score between 0 and 10, a larger number indicating more active disease. When using the score to assess response to treatment, a DAS-28 reduction by 0.6 represents a moderate improvement, while a reduction more than 1.2 represents a major improvement.

The DAS28 ESR calculator is based on the original DAS28 rheumatoid arthritis disease activity score but instead of C-reactive protein, the erythrocyte sedimentation rate is used as marker of inflammation.
