Abstract

Introduction

Early diffuse cutaneous systemic sclerosis (dcSSc) is characterized by rapid changes of skin and internal organs. Our objective was to develop a composite response index in dcSSc (abbreviated CRISS) for use in randomized controlled trial (RCT.

Methods

We developed 150 paper patient profiles with standardized clinical outcome elements (core set items) using patients with dcSSc. Forty scleroderma experts rated 20 patient profiles each and assessed whether each patient had improved or not over a period of 1 year. Using profiles where raters reached a consensus on whether the patients were improved vs. not (79% of profiles examined), we fit logistic regression models where the binary outcome referred to whether the patient was improved or not, and the change in the core set items from baseline to follow-up were entered as covariates. We tested the final index in a previously completed RCT.

Results

Sixteen of 31 core items were included in the patient profiles after a consensus meeting and review of test characteristics of patient-level data. The logistic regression model that included the following core set items: changes in the Rodnan skin score, forced vital capacity (FVC)% predicted, patient and physician global assessments, and HAQ-DI over 1 year had sensitivity of 0.982 (95%CI: 0.981-0.983), specificity of 0.931 (95% CI: 0.930-0.932), and had the highest face validity. Subjects with a significant decline in renal or cardiopulmonary involvement were classified as not improved, regardless of improvements in other core items. The index was able to differentiate the effect of methotrexate from placebo in a 1-year RCT (p< 0.05).

Conclusion

We have developed CRISS that is appropriate for use as an outcome assessment in RCT of early dcSSc.

<title>Introduction</title>
<p id="P1">Early diffuse cutaneous systemic sclerosis (dcSSc) is characterized by rapid changes of skin and internal organs. Our objective was to develop a composite response index in dcSSc (abbreviated CRISS) for use in randomized controlled trial (RCT.</p>
</sec>
<sec id="S2">
<title>Methods</title>
<p id="P2">We developed 150 paper patient profiles with standardized clinical outcome elements (core set items) using patients with dcSSc. Forty scleroderma experts rated 20 patient profiles each and assessed whether each patient had improved or not over a period of 1 year. Using profiles where raters reached a consensus on whether the patients were improved vs. not (79% of profiles examined), we fit logistic regression models where the binary outcome referred to whether the patient was improved or not, and the change in the core set items from baseline to follow-up were entered as covariates. We tested the final index in a previously completed RCT.</p>
</sec>
<sec id="S3">
<title>Results</title>
<p id="P3">Sixteen of 31 core items were included in the patient profiles after a consensus meeting and review of test characteristics of patient-level data. The logistic regression model that included the following core set items: changes in the Rodnan skin score, forced vital capacity (FVC)% predicted, patient and physician global assessments, and HAQ-DI over 1 year had sensitivity of 0.982 (95%CI: 0.981-0.983), specificity of 0.931 (95% CI: 0.930-0.932), and had the highest face validity. Subjects with a significant decline in renal or cardiopulmonary involvement were classified as not improved, regardless of improvements in other core items. The index was able to differentiate the effect of methotrexate from placebo in a 1-year RCT (p< 0.05).</p>
</sec>
<sec id="S4">
<title>Conclusion</title>
<p id="P4">We have developed CRISS that is appropriate for use as an outcome assessment in RCT of early dcSSc.</p>
