Survey shows low drug adherence worsens rehospitalisation risk in heart failure patients, indicating need for better interventions.

The research aimed to evaluate how medication adherence affects outcomes after hospitalization for heart failure.
Included patients discharged after heart failure hospitalization from a national multicentre cohort
Matched records with the National Healthcare System database for claims and clinical events
Measured adherence using proportion of days covered (PDC) for beta blockers and inhibitors
Defined low adherence as PDC < 80% for at least one drug class during two-year follow-up
34% of patients were classified as having low drug adherence
Two-year mortality rates were similar between adherent (16.9%) and low-adherent groups (19.1%)
Adherent patients had lower rates of all-cause rehospitalisations (85.9% vs. 92.8%) and heart failure rehospitalisations (48.5% vs. 58.2%) at two years

Lenglet et al. (2026) studied this question.
