Monitoring contamination of hazardous drug compounding surfaces at hospital pharmacy departments. A consensus statement. Practice guidelines of the Spanish Society of Hospital Pharmacists (SEFH)

Abstract

Objective: To establish a series of recommendations based on available evidence for monitoring surface contamination in the areas devoted to compounding hazardous drugs in pharmacy departments. Method: Based on a literature search in the Medline and Embase databases (search period: January 2009 to July 2019), as well as on a review of standards and recommendations issued by different healthcare organizations, a committee of experts from the Spanish Society of Hospital Pharmacists defined a series of safe practices for handling hazardous drugs and monitoring compounding work surfaces. Recommendation decisions were adopted by consensus among the members of the expert group, considering the recommendations reviewed, the monitoring situation in Spanish hospital departments, and the associated costs. Results: Ten recommendations were formulated, structured into eight sections. They include aspects related to the drugs to be monitored; the areas to be monitored; when samples should be taken; risk determination and preparation of a sampling protocol; analytical techniques; contamination thresholds; and design of an action plan based on the sampling and decontamination results obtained. Conclusions: Surface monitoring allows hazardous drugs detection and evaluation of the effectiveness of current protocols for the safe handling of such drugs in hospital pharmacy departments. The evaluation should include an analysis of the efficacy of engineering controls, work practices and cleaning and decontamination processes.
