Assessment of Machine Learning vs Standard Prediction Rules for Predicting Hospital Readmissions.

Importance: Hospital readmissions are associated with patient harm and expense. Ways to prevent hospital readmissions have focused on identifying patients at greatest risk using prediction scores.

Objective: To identify the type of score that best predicts hospital readmissions.

The Arthritis, Diet and Activity Promotion Trial (ADAPT): design, rationale, and baseline results.

Osteoarthritis (OA) of the knee leads to restrictions of physical activity and ability to perform activities of daily living. Obesity is a risk factor for knee OA and it appears to exacerbate knee pain and disability. The Arthritis, Diet, and Activity Promotion Trial (ADAPT) was developed to test the efficacy of lifestyle behavioral changes on physical function, pain, and disability in obese, sedentary older adults with knee OA.
