Effects of “Comprehensive Support” in Meta-Regression Analysis

Study Characteristic Number of Studies Relative Risk of Readmission Compared to Reference^ 95% Confidence Interval P value
Comprehensive Support Category 1 (0 points) 15 1 (reference)
Comprehensive Support Category 2 (1 or 2 points) 20 0.82 0.66 to 1.02 0.07
Comprehensive Support Category 3 (3 or 4 points) 7 0.63 0.43 to 0.93 0.02
Publication in 2002 or After 33 1.47 1.10 to 1.96 0.01

The “Comprehensive Support” variable returned one point each for interventions that 1.) were rated to increase patient capacity, 2.) had five or more unique intervention activities, 3.) had five or more meaningful patient interactions, and 4.) had two or more individuals involved in its delivery.
