Heart transplant recipients experience high multimorbidity and therapeutic complexity. The Medication Regimen Complexity Index identifies factors contributing to this complexity, aiding in developing reduction strategies.
Area of Science:
- Cardiology
- Pharmacology
- Transplantation Medicine
Background:
- Multimorbidity and therapeutic complexity are significant challenges in heart transplant (HTx) recipients.
- Quantifying this complexity and identifying reduction strategies remain areas needing further investigation.
Purpose of the Study:
- To assess multimorbidity and medication regimen complexity in adult heart transplant recipients (HTxR) more than 1.5 years post-transplant.
- To identify predictors of medication regimen complexity and its impact on clinical outcomes.
Main Methods:
- Single-center, observational study of 135 chronic-stage HTxR.
- Assessment of multimorbidity (>2 comorbidities) and the patient-level Medication Regimen Complexity Index Spanish version (pMRCI-S).
- Analysis of independent predictors of pMRCI-S and its association with clinical variables.
Main Results:
- Comorbidities significantly increased post-HTx (6±3 vs 2±2).
- HTxR took an average of 12±3 chronic drugs daily, with 58% treating comorbidities.
- Mean pMRCI-S score was 42±11, higher than in other chronic diseases; comorbidity-related medications predicted higher complexity.
- Therapeutic complexity impacted solid malignancies and renal function.
Conclusions:
- Multimorbidity and pMRCI-S scores were notably high in the HTx population.
- The pMRCI score effectively identifies factors driving therapeutic complexity post-HTx.
- This index can guide the selection of strategies to mitigate therapeutic complexity.
