Insights
This study shows that increased clinic visits can improve medication adherence in pediatric liver transplant patients. The intervention led to fewer high liver enzyme levels and rejection episodes, suggesting a promising approach for better patient outcomes.
Area of Science:
- Pediatric Gastroenterology
- Transplant Medicine
- Clinical Pharmacology
Background:
- Medication adherence is critical for pediatric liver transplant recipients.
- Non-adherence can lead to poor medical outcomes, including graft rejection and liver dysfunction.
- Tacrolimus blood levels are a key indicator of adherence in these patients.
Purpose of the Study:
- To evaluate an adherence-improvement protocol for pediatric liver transplant patients.
- To assess the impact of increased clinic visits on medical outcomes and medication adherence.
- To determine the cost-effectiveness of the adherence intervention.
Main Methods:
- A clinical program followed 23 children and adolescents undergoing liver transplant.
- Non-adherent patients were identified using tacrolimus blood levels.
- Intervention involved increasing clinic visit frequency for non-adherent patients.
- Outcomes were compared between a two-year pre-intervention period and the intervention period.
Main Results:
- The number of patients with high alanine aminotransferase levels (≥100) significantly decreased post-intervention (8 to 4).
- Rejection episodes decreased from three pre-intervention to none post-intervention.
- Improved adherence to tacrolimus was observed, though not statistically significant.
- The intervention did not result in increased outpatient costs.
Conclusions:
- An adherence-improvement intervention involving increased clinic visits shows promise for pediatric liver transplant recipients.
- The protocol demonstrated potential in improving key medical outcomes.
- Larger, controlled studies are necessary to confirm the efficacy of this intervention.
Abstract:
We describe results from a clinical program, which aimed at improving adherence to medications in children who had a liver transplant. We followed the medical outcomes of 23 children and adolescents who participated in a clinical adherence-improvement protocol during the years 2001-2002. The protocol included identification of non-adherent patients by examining tacrolimus blood levels and intervention by increasing the frequency of clinic visits for non-adherent patients. In the two-yr preintervention (1999-2000), there was no improvement in any of the outcomes. After the intervention, the number of patients with high alanine aminotransferase levels (100 and above) decreased significantly, from eight before the intervention to four afterwards. Other outcomes, including the number of rejection episodes (three before, none after) and the degree of adherence to tacrolimus, also improved, but the improvement did not reach statistical significance. Although non-adherent patients were called to clinic more often under the protocol, the intervention did not lead to increased outpatient costs. This adherence--improvement intervention appears to be promising in improving outcomes in pediatric liver transplant recipients. Larger, controlled studies are needed to establish the efficacy of this or other approaches.
