The Association of Readmission Reduction Activities with Primary Care Practice Readmission Rates

Area of Science:

• Health Services Research
• Primary Care Medicine
• Healthcare Quality Improvement

Background:

• Hospitals significantly influence readmission rates, but primary care practices also play a crucial role.
• Limited empirical evidence exists on primary care characteristics linked to reduced hospital admissions.

Purpose of the Study:

• To investigate the association between primary care practices' readmission reduction activities and their observed readmission rates.
• To identify specific primary care strategies that contribute to lower hospital readmission rates.

Main Methods:

• Retrospective analysis of 1,788 primary care practices using survey data (2017-2018) and Medicare claims (2016).
• Development of a composite score (0-1) based on 12 identified readmission reduction capabilities.
• Use of mixed-effects logistic and linear regression models to assess the relationship between activities and readmission rates.

Main Results:

• Increased engagement in readmission reduction activities was significantly associated with lower readmission rates (P < .05).
• Each additional activity correlated with an average 0.05 percentage point decrease in readmission rates.
• Practices performing ≥10 activities had 1 full percentage point lower risk-standardized readmission rates compared to those performing none.

Conclusions:

• Primary care practices employing more readmission reduction activities demonstrate lower patient readmission rates.
• The findings emphasize the importance of implementing multiple, coordinated activities for effective readmission reduction, rather than relying on single interventions.
