Poster Title:Inpatient 30-Day Readmission Prediction using cTAKES Poster abstract: Hospital readmissions are costive and potentially preventable. Approximately 3.3 million of adult patients were readmitted to hospitals within 30 days of discharge in 2011 with an estimated cost for the hospitals of 3.3 billion dollars according to the Center for Medicare and Medicaid Services. Up to 79% of readmissions can be potentially preventable. Most current tools for predicting 30-day readmissions only rely on structured data such as the number of inpatient visits in last 6 months, demographic information, etc. However, most detailed patient symptoms, findings and diagnosis are locked in clinicians’ reports that are in free-text form. We have developed the System for Hospital Adaptive Readmission Prediction and Management system (SHARP) that employs cTAKES, an open-source natural language processing (NLP) platform, to extract clinical findings from clinicians’ reports, and applies machine-learning algorithms to identify patients with risk of 30-day readmissions. We compared the performance of SHARP using cTAKES and MedLEE, a state-of-the-art NLP tool, by applying them to freetext clinician reports of heart failure (HF) patients at UPMC.

Amie gave outstanding talk at the NLM talk NLM Informatics Training Conference, the title of the talk is "Using Laboratory Data for Prediction of 30-Day Hospital Readmission: A Retrospective Study. Time: 2015 Jun 23 - 24. Bethesda, MD.​"

Abstract: Prior work in readmission risk prediction has under-utilized laboratory data, which may provide valuable information about a patient’s condition. We aim to assess the contribution of laboratory data in predicting readmission risk. Preliminary work has focused on pediatric seizure, which has the highest volume of pediatric readmissions but no identified readmission risk factors. We used discharge diagnosis ICD-9 codes to identify seizure-specific visits to Children’s Hospital of Pittsburgh of UPMC during 2007-2012. Patients were considered readmitted if they returned to the hospital within 30-days post-discharge. We extracted features to summarize laboratory data for each patient. We used a training dataset (2007-2011) to rank features with information gain ratio and added features to a baseline model in order of rank. We kept features that improved prediction accuracy under 10-fold cross validation. A test (held-out) dataset (2012) was used to compare the AUROCs of the baseline model and the model with the added laboratory features. The addition of laboratory features significantly improved the prediction ability of the model, which suggests that laboratory data may be useful in identifying patients at risk of readmission. Ongoing work includes examining the contribution of laboratory data to readmission risk in adult heart failure patients.

Amie's poster "Using Laboratory Data for Prediction of 30-Day Hospital Readmission of Pediatric Seizure Patients" presented at AMIA 2014 Annual Symposium, Washington D.C. won the AMIA 2014 Distinguished Poster Award!

Abstract: Laboratory data may provide valuable clinical information related to a patient’s risk of readmission. This study assessed the contribution of laboratory data in predicting readmission risk for pediatric seizure patients. We extracted basic summary features from laboratory data and selectively incorporated them into a baseline prediction model to determine if readmission prediction accuracy could be improved. We found that the added features from laboratory data increased the model’s AUROC from 0.55 to 0.63 with borderline significance (p-value=0.023).
