Study Details

Study Description

Brief Summary

This study developed the first prediction model for risk of critical ITP bleeds for ITP inpatients using a novel machine learning algorithm. This model has been implemented as a web-based model so that clinicians can obtain the estimated probability of critical ITP bleeds for ITP inpatients. The objective of this study is to prospectively and externally validate the risk of critical ITP bleeds in newly admitted ITP patients.

Condition or Disease Intervention/Treatment Phase

    Detailed Description

    Primary immune thrombocytopenia (ITP) is a common acquired autoimmune disease characterized by reduced platelet production and increased platelet destruction due to autoimmune disorders, as patients present with low platelet counts and a high risk of bleeding. Although most ITP patients present a good prognosis, the rare but important critical ITP bleeds events are the threatening-life complication to ITP patients, severely affecting their prognosis, quality of life and treatment decisions.

    More recently, the development of clinical prediction models has provided powerful tools for precision diagnosis and early intervention of diseases, especially the application of machine learning methods. Machine learning approaches can overcome some of the limitations of current risk prediction analysis methods by applying computer algorithms to large data sets with numerous multidimensional variables, capturing the high-dimensional nonlinear relationships between clinical features to produce data, drive outcome prediction.

    It suggests an unmet need for personalized patient management strategies and an urgent need for effective tools to predict the risk of critical ITP bleeds in hospitalized patients in medical practice.

    Here, we aim to integrate clinical and laboratory data based on a nationwide multicenter study in China to build a clinical prediction model. In particular, we also perform external and prospective validation with large sample sizes to improve the robustness and utility of our models.

    It is a simple and convenient tool to quickly assess newly admitted ITP patients and achieve early identification and intervention for those at high risk of life-threatening bleeding events, thus reducing disability and mortality rates in the future.

    Arms and Interventions

    Arm Intervention/Treatment
    ITP inpatients

    The study population included nonsplenectomized primary ITP inpatients 18 years of age or older. Patients who had a diagnosis of connective tissue disease, cancer (solid tumor or leukemia), or primary immune deficiency were excluded.

    Outcome Measures

    Primary Outcome Measures

    1. Performance of model [3 months]

      Area under receiver operating characteristic curve (AUC) of the model in predicting critical ITP bleeds in patients with ITP.

    Secondary Outcome Measures

    1. Comparison between different machine learning algorithms used in the model [3 months]

      Comparison of sensitivity and specificity of different machine learning algorithms used in the model.
