Decreasing Heart Failure Patients

Looking for PICO questions for decreasing Heart Failure Patients ‘ day readmission rates. Can you please check my PICO question below? If not, plz let me know a better PICO Q.

In heart failure patients ages 65 and older who are going to be discharged, does post-discharge interventions result in a decline in 30-day hospital readmission rates compared to not receiving follow-up interventions?
