Rasch models enable individual-level QoL change assessment after heart surgery; leaves open whether they should replace traditional scores in practice or trials.
Observational (n=98)
p-value: p=<0.0001
Rasch models provide a valid framework for measuring individual-level change in patient-reported health status during cardiac rehabilitation, overcoming limitations of traditional ordinal score approaches.
Anselmi et al. (2015) conducted an observational in Heart surgery (n=98). Cardiac rehabilitation program vs. Baseline (pre-intervention) was evaluated on Change in Perception of Positive Change scale (p=<0.0001). Cardiac rehabilitation resulted in a significant overall improvement in the perception of positive change, with Rasch analysis identifying significant individual improvement in 13 patients and worsening in 3.
