[IMPACTCHIMIO: Development and multicentric validation of a tool for collecting pharmaceutical interventions carried out within chemotherapy reconstitution units].

OBJECTIVES:To develop and validate prospectively a specific tool for pharmaceutical interventions performed in centralized cytotoxic preparation units. METHODS:A pharmaceutical intervention is defined as a type of intervention performed in relation to a problem encountered. ImpactChimio is derived from the Act-IP® (SFPC) tool. The initial version (version 1) was developed from the pharmaceutical interventions collected over 1 year by the pilot centre. Its validation was carried out by the Delphi method via a prospective multicentric collection to assess its robustness (real life pharmaceutical interventions) and reproducibility (50 pharmaceutical interventions classified by pharmacists naive or not to the tool and study of classification divergences). RESULTS:The development of the tool (version 1) was based on the analysis of 412 pharmaceutical interventions. For its validation, 196 pharmaceutical interventions were provided by 6 centers for 5 months. The changes have been incorporated into the new versions of the tool (version 2 and version 3). Six naive and six non-naive pharmacists then tested reproducibility by reclassifying 50 selected pharmaceutical interventions into version 3. A total of 136 discrepancies (11.3 %) were found out of 1200 responses: 66 related to the problem encountered and 70 to the type of intervention. No statistically significant differences were found between naive and non-naive pharmacists. CONCLUSIONS:ImpactChimio is the first pharmaceutical interventions' specific tool for centralized cytotoxic preparation units, developed and validated by a multicentric study using the Delphi method. It makes possible to enhance the value of the analysis activity and to identify training areas for the teams.
