01 Mar Medalogix Helps Signifigantly Reduce Avoidable Hospital Readmissions. Our Data Scientist Can Prove It.
- It’s built in automated calling function augments in-person home health visits with IVR or scheduled manual calls. This helps improve patients care.
- Helps improve patient satisfaction. More touchpoints via automated calling typically helps patients feel more at ease because they know they’re being checked on in between visits.
- By predicting and ranking which patients are most at risk for readmission, you can help ensure busy clinicians are dedicating their attention where it’s most needed at that specific time.
The goal of the study is to estimate the effect of Medalogix Touch application at a home health agency (HHA) on reducing their patients’ transfer to hospital, skilled nursing facilities or hospice. It is an observational study in which patient and outcome data are collected retrospectively. An immediate challenge is the selection bias due to the nonrandomized nature of the observational study. The study uses propensity score matching to address such potential treatment selection bias and from which to estimate the genuine average effect of the treatment for the treated (ATT).
Propensity score one-to-one matching method is adopted. First, the Medalogix research team estimated a logistic regression model in which the treatment status (under Medalogix Touch care) is regressed on patient’s observed baseline characteristics. Second, patients are scored by the model. One-to-one score matching is implemented to select control patients who are the closest to the treated patients with respect to the logit of their propensity scores. The threshold difference is 0.20 of a standard deviation of the logit of the propensity scores. After matching, the analysis on outcome provides a valid estimate of treatment effect because the research method compares patients with matched observed characteristics, all of whom are potential candidates for the treatment.
Model Validation and Robustness
The Medalogix research team uses the re-sampling technique (bootstrapping 3,000 times) on matched pairs to test for the robustness of estimates. Bootstrapping has the advantage of distribution-free assumptions on estimate testing.
