INTRODUCTION: Drug related problems (DRP) can lead to severe consequences in kidney recipients. The aim of the study was to assess the impact of the clinical pharmacist interventions on the incidence of DRP. METHOD: The number of DRP were evaluated according to 3periods: Without intervention, with medication reconciliation at admission, and with medication reconciliation at admission associated with an interview with the clinical pharmacist at discharge. RESULTS: Patients concerned were mainly men, 55years old (median age), stage3 of CKD, transplanted for less than 3months or more than 1year, with cardiovascular risk factors and receiving an average of 9drugs/day. Among the DRP, 20% were avoidable and severe in most cases. In period1, 27.7% patients had at least 1DRP, in period2, 21.3% patients had at least 1DRP, and in period3, 17.4% of patients had at least 1DRP (P=0.03). One hundred and ten patients had medication reconciliation at admission with a mean of 0.6unintentional discrepancies per patient (omission in 81% of cases). The main drugs involved concerned the digestive-metabolic (24.5%), cardiovascular (23%), and nervous (23%) system. Sixty-eight interviews at discharge were realized and revealed self-medication habits. CONCLUSION: Our study shows that medication reconciliation at admission associated with an interview with the clinical pharmacist at discharge can help to reduce DRP in kidney recipients. Further studies are needed to confirm our results.
