What is it about?
the emergence of the Hospital Readmission Reduction Program of the Center for Medicare and Medicaid Services on October 1, 2012, forecasting unplanned patient readmission risk became crucial to the healthcare domain. There are tangible works in the literature emphasizing on developing readmission risk prediction models; However, the models are not accurate enough to be deployed in an actual clinical setting. Our study considers patient readmission risk as the objective for optimization and develops a useful risk prediction model to address unplanned readmissions. Furthermore, Genetic Algorithm and Greedy Ensemble is used to optimize the developed model constraints.

Why is it important?
It is a fact that the federal budget of the United States is concerned by the burgeoning healthcare expenses (Shipeng Yua, 2015). One of the main factors contributing to the healthcare cost is the avoidable patient readmission. Unplanned patient readmission has been a significant measure of care quality. However, the Affordable Care Act of 2010 introduced the Readmission Reduction Program which became effective on October 1, 2012. According to the School of Public Health, Veterans Administration can save $2,140 per patient by managing patients prone to readmission (Kathleen Carey, 2016). Moreover, studies have shown that 15 to 25 percent of discharged patients are readmitted in less than 30 days. According to the Agency for Healthcare Research and Quality, about 1.8 million patients were readmitted (Anika and Hines, 2014). Fierce Healthcare reported that in 2011, hospitals spend $41.3 billion to treat unplanned readmitted patients (Shinkman, 2014). A study published by Harvard Business Review stated that prioritized and effective communication with the patient and complying to evidence-based care standards could check patient readmission rate by 5 percent (Claire Senot, 2015). However, fostering desired communication within a hospital is arduous due to the complexity of the system. Our study focuses on predicting patient readmission. Individuals with a high risk of readmission can be provided with alternative preventive measures such as intensive post-discharge care or home care (Davood Golmohammadi, 2015).
Perspectives
In this study, we implement a predictive analytical approach to identify patients prone to readmission and thus, systematically reduce the number of avoidable readmissions mainly caused by patient non-compliances to medication instruction or early discharge from hospital. Our proposal has the capability of capturing both patient and population-based variations of hospital readmissions. It incorporates patient with diverse health concerns across 130 US hospitals. The novelty of our method is to directly incorporate patients’ history of readmissions into modeling framework along with other demographic and clinical characteristics. We also verify the effectiveness of the proposed approach by validating training accuracy. Some contributions made in this paper are (i) applying Boruta algorithm and stepwise variable selection and (ii) implementing genetic and greedy ensemble algorithm to optimize our predictive models.
