Hospital Discharge Planning: Assisting healthcare providers in identifying patients at higher risk of readmission for enhanced post-discharge care planning.Clinical Decision Support: Integrating with Electronic Health Records (EHR) to provide clinicians with real-time risk assessments during hospitalization.Quality Improvement Initiatives: Using the LACE score data to inform hospital policies aimed at reducing readmission rates, which can improve patient outcomes and potentially lower costs.Research Applications: Facilitating research studies on patient readmissions and outcomes by providing a standardized measure of readmission risk.

Data Dependent: The accuracy of the LACE score is highly dependent on the quality and completeness of the input data.Static Model: The LACE index is a static model and may not capture the nuances of individual patient circumstances or changes over time. Population Specific: The LACE index was initially validated in certain populations in Ontario, Canada. Although it's now validated in several populations, its performance can vary depending on the demographics or clinical settings.

The LACE Score Calculator calculates patients' LACE indices. The LACE index—an acronym for Length of stay, Acuity of admission, Comorbidities, and Emergency department visits—itself is a predictive model to estimate the risk of post-hospital discharge readmission or death within 30 days. More details of the algorithm can be found at https://txhca.org/app/uploads/2015/08/Aug.-2015-LACE-Tool.pdf. The LACE index is based on "Derivation and validation of an index to predict early death or unplanned readmission after discharge from hospital to the community" (published in 2010 in CMAJ), a prospective cohort study that analyzed data from over 4,800 patients discharged from hospitals in Ontario, Canada. This study used a split-sample design to derive and validate an index (LACE) to predict the risk of death or nonelective readmission within 30 days after discharge. Then, this index was externally validated using administrative data in a random selection of 1,000,000 Ontarians discharged from hospital between 2004 and 2008; in both the internal validation cohort and the external validation group, the LACE index could predict patients' risk of 30-day readmission (C statistic 0.6935 (internal validation cohort) and 0.684 (external validation group)). Subsequent studies confirm the index’s predictive validity across diverse patient populations. The strength of the LACE index lies in its simplicity and the use of readily available hospital data, making it a practical and accessible tool for healthcare providers. By quantifying key factors that influence patient outcomes after discharge, the LACE index provides a systematic approach to risk stratification. This model has been adopted in various healthcare settings globally.

I have a Bachelor of Science in Molecular, Cellular, and Developmental Biology (MCDB) and Computer Science from the University of Michigan-Ann Arbor.

The LACE Score Calculator aims to streamline the process for hospitals to evaluate readmission risks, thus freeing up clinicians to focus on patient care. Looking ahead, I'm excited about enhancing the app with a peer-reviewed AI model that's shown to outperform the traditional LACE index.
