Randomized trial of stage-based interventions for informed Medicare choices.

Levesque DA, Cummins CO, Prochaska JM, Prochaska JO - Health Care Financ Rev (2006)

Bottom Line: The TTM-based interventions also increased use of and satisfaction with traditional Medicare education materials among most enrollees.The interventions' impact on stage of change for comparing plans was observed only among treatment group participants who had examined and evaluated the materials.The challenges to increasing informed choice and possible dissemination channels for stage-based materials are discussed.

ABSTRACT
A randomized trial involving 1,351 new Medicare enrollees was conducted to assess the efficacy of a transtheoretical model (TTM) based manual and multimedia expert system program that delivered guidance and feedback matched to individual stage of readiness to compare Medicare health plans. At 6 months post-intervention, compared to enrollees in the control group, those receiving the manual plus expert system intervention or the manual alone exhibited greater increases in Medicare knowledge. The TTM-based interventions also increased use of and satisfaction with traditional Medicare education materials among most enrollees. The interventions' impact on stage of change for comparing plans was observed only among treatment group participants who had examined and evaluated the materials. The challenges to increasing informed choice and possible dissemination channels for stage-based materials are discussed.

f1-hcfr-27-4-025: Medicare Knowledge for Two Treatment and Control Groups at Baseline and 6 Months Followup

Mentions: Figure 1 shows Medicare knowledge scores at baseline and followup for Sample One and Sample Two treatment and control groups. There was a within-subjects effect for time (mean knowledge scores increased from 4.0 (SD=1.9) at baseline to 4.4 (SD=1.8) at followup, F(1,1024)=46.9, p<0.001, η2=0.044), and a between-subjects effect for subsample (knowledge scores were higher in Subsample One, F(1,1024)=24.3, p<0.001, η2=0.023). There was an effect for condition × time (F(1,1024)=12.3, p<0.001, η2=0.012), indicating that treatment group participants showed greater gains in Medicare knowledge over time than control group participants. No effect was found for condition × subsample × time (F(1,1024)=0.8, p=0.38, η2=0.001), indicating that the pattern of treatment-control group differences in Subsample One was not different from the pattern in Subsample Two.
