Smart automation in cleanrooms: Metasys enhances sterile compounding compliance at Geisinger
Authors: Nichole Varela-Gonzalez and Adam Castro
In hospital cleanrooms, where sterile compounding and infusion medication preparation occur, maintaining strict environmental controls is essential to patient safety and regulatory compliance. As standards governing compounding spaces have become increasingly rigorous — particularly with the implementation of USP <797> and USP <800> — the need for continuous monitoring and documentation of temperature, pressure and humidity has grown more critical than ever. These environmental parameters directly impact the integrity of sterile preparations and the reliability of pharmacy operations.
Historically, limitations in temperature tracking technology have prevented pharmacy teams from gaining real-time visibility into room pressure conditions. This gap in monitoring has led to instances where cleanrooms had a loss of air pressure without immediate alerts. When such deviations go unaddressed for more than 30 minutes, staff are required to perform a full disinfection process before sterile compounding operations can resume. At non-24-hour sites, this often results in staff arriving to find pressure conditions out of range, prompting urgent remediation efforts and delaying the start of the workday — ultimately impacting patient care and operational efficiency.
To address these challenges, Geisinger implemented Metasys, the flagship building automation system developed by Johnson Controls. Metasys provides a comprehensive solution that delivers real-time, actionable data across temperature, pressure and humidity parameters. This empowers pharmacy teams with the insights needed to maintain controlled environments and ensure compliance with USP <797> and <800> standards. The system has enabled consistent, safe compounding of infusion medications, supporting the timely delivery of patient care.
Metasys allows pharmacy facilities to customize schematics to match the layout and specifications of individual pharmacy spaces. It supports proactive management of sterile compounding environments by continuously monitoring and electronically logging environmental conditions. The system provides 24-hour access to regulatory metrics and serves as the data backbone for the building maintenance system. By offering a single source of truth for critical environmental values, Metasys enables pharmacy teams to respond quickly and effectively to deviations. Automated alarms are triggered when parameters fall outside acceptable ranges, and all changes and alerts are recorded with time-stamped audit trails to support compliance and accountability.
Impact and outlook
Through the integration of Metasys, Geisinger has positioned its Enterprise Pharmacy sites at the forefront of regulatory excellence, operational resilience and patient-centered innovation. This investment not only enhances environmental integrity, but also strengthens the safety and efficiency of sterile compounding practices. As Geisinger continues to evolve its infrastructure and adopt advanced technologies, the implementation of smart automation systems like Metasys demonstrates how innovation can drive compliance, reduce risk and improve outcomes across the health system.
