Clinical evaluation of pharmacists’ interventions on multidisciplinary lung transplant outpatients’ management: results of a 7-year observational study

OBJECTIVES: Lung transplant (LT) recipients require multidisciplinary care because of the complexity of therapeutic management. Pharmacists are able to detect drug-related problems and provide recommendations to physicians through pharmacists’ interventions (PIs). We aimed at assessing the clinical impact of PIs on therapeutic management in LT outpatients. DESIGN: Data were collected prospectively from an LT recipients cohort during 7 years. A multidisciplinary committee assessed retrospectively the clinical impact of accepted PIs. SETTING: French University Hospital. PARTICIPANTS: LT outpatients followed from 2009 to 2015. PRIMARY OUTCOME MEASURES: Clinical impact of PIs performed by pharmacists using the CLEO tool and the Pareto chart. RESULTS: 1449 PIs led to a change in patient therapeutic management and were mainly related to wrong dosage (39.6%) and untreated indication (19.6%). The clinical impact of PIs was ‘avoids fatality’, ‘major’ and ‘moderate’, in 0.1%, 7.0% and 57.9%, respectively. Immunosuppressants, antimycotics for systemic use and antithrombotic agents had the greatest clinical impact according to the Pareto chart. PIs related to drug–drug interactions (10%) mainly had a moderate and major clinical impact (82.3%, p<0.0001). CONCLUSION: Clinical pharmacists play a key role for detecting drug-related problems mostly leading to a change in therapeutic management among LT outpatients. Our study provides a new insight to analyse the clinical impact of PIs in order to target PIs which have most value and contribute to patient care through interdisciplinary approach.
