Evaluating the Strength of the Association and Predictability of Risk Factors and Hospital Readmission

Abstract

Background: Hospital readmission is still a major public health problem. In many counties, there are the incidents that affected to performance of quality in the hospital. Objective: To evaluate the strength of association and predictability of risk factors and hospital readmission. Methods: The data of 160 patients referred to home health care unit at Ramathibodi Hospital were collected using risk assessment of unplanned readmission within 28 days. The strength of association and predictability of risk factors and hospital readmission were performed using relative risk (RR) and logistic regression. Results: Factors significantly related to hospital readmission were number of previous hospital admission more than 1 time within the last 12 months (RR > 4), age more than 70 years (RR > 2), pneumonia (RR > 2), and diabetes (RR < 1). The predictability of 2 factors model including number of previous hospital admission more than 1 time within the last 12 months and diabetes was 86.3%. Conclusions: Risk factors significantly associated with hospital readmission were number of previous hospital admission more than 1 time within the last 12 months, age more than 70 years, pneumonia, and diabetes. Number of previous hospital admission more than 1 time within the last 12 months and diabetes factors can be predicted hospital readmission.
