Pharmacy Purchasing & Products: What exposure risks exist during hazardous drug preparation and administration?
UNC Hospitals: Hazardous drugs, including chemotherapy, pose exposure risks at several points throughout the medication-use process. During preparation, risk occurs when reconstituting lyophilized drugs, spiking vials, transferring the drug to IV bags and syringes, and cleaning drug preparation areas. Exposure can occur through aerosolization of the drug and external contamination of the medication vial. In addition, exposure may occur when IV lines are primed and syringes are connected or disconnected from injection ports; this is especially true if a closed system transfer device (CSTD) is not used to prevent droplet formation.
There are additional—perhaps less obvious—areas in the medication-use process where exposure could occur. Hospitals must fully assess the possibility for hazardous drug exposure in all areas hazardous drugs are used, including:
PP&P: What is the best approach for developing safe handling policies and procedures (P&Ps) for hazardous drugs that cover all employees?
UNC Hospitals: Input from a multidisciplinary team is vital to develop safe handling P&Ps. Participation from receiving, pharmacy, nursing, and environmental services will ensure that the recommendations are comprehensive enough to protect all employees, and engaging staff in the process ensures that all departments buy-in to the process.
A multidisciplinary approach was utilized to implement several P&Ps at the UNC Cancer Hospital Infusion/Inpatient Pharmacy (CHIP) to reduce exposure risk and create safe handling practices. Elements of these P&Ps include:
These practices are included in a hospital-wide policy developed in collaboration with pharmacy, nursing, physicians, environmental services, and environmental health and safety. The chemotherapy policy is reviewed semi-annually at the oncology pharmacy and therapeutics (P&T) subcommittee, which is composed of representatives from these departments.
PP&P: What staff training and monitoring is required to ensure safe use of hazardous drugs?
UNC Hospitals: As part of our safe handling P&P, personnel working directly with hazardous drugs must complete formal training. Pharmacy technicians responsible for the preparation of hazardous drugs complete a six- to eight-week training program, which includes computer-based modules (purchased from a vendor), practical hands-on experience, and competency assessments (developed in-house). Computer-based modules cover aseptic technique, cleaning and disinfecting procedures, personnel garbing techniques, hazardous drug handling, waste disposal (see TABLE 2 for UNC Hospitals’ Pharmaceutical Waste Disposal Guidance Grid), and cleanup procedures. The hands-on portion of the training program teaches preparation practices within a BSC, including cleaning procedures, proper use of CSTDs, and preparing various chemotherapy and hazardous admixtures. Upon completion of both computer-based and practical training, the technician must demonstrate competency in all of these tasks through a written and a practical exam using media-fill challenge kits.
CHIP technicians complete both baseline and annual competencies. Once training is complete and competency is established, each technician’s aseptic technique is tested annually using media-fill challenge tests, as mandated by USP <797>. Pharmacists also complete robust training followed by a competency exam; a new exam is created each year, which pharmacists complete prior to their annual evaluation (see SIDEBAR 1).
PP&P: How should practice challenges be identified?
UNC Hospitals: Areas needing improvement are assessed in various ways. Review of staff-reported near miss errors in which they intervened, regular communication with employees within the pharmacy, and continual vigilance to identify issues brought forward by nursing, medical staff, and hospital administrators can assist pharmacy in addressing areas of concern to ensure safety and improve services.
UNC Hospitals recently completed a review of its medication preparation activities with the goal of reducing the time required to safely prepare a medication. Because extended wait times in the infusion clinic are consistently associated with dissatisfied patients, CHIP undertook a Lean Six Sigma Kaizen event in June 2013 to improve the turnaround times of medication preparation while maintaining safety. Participants included CHIP pharmacy staff, non-oncology pharmacists, oncology nursing, quality and business analysts, oncology leadership, and an infusion patient. Experimental trials were performed to identify areas where operational changes could be made to improve effectiveness, efficiency, and safety. The top three challenges identified by the Kaizen included:
These challenges were resolved by shifting the responsibility for the second independent check (of the chemotherapy order, and then of the order against the label) to an additional pharmacist outside the cleanroom before preparation of the final product inside the cleanroom. Thus, the order was checked by two pharmacists outside the cleanroon prior to being prepared, thereby reducing waste and allowing the cleanroom pharmacist to focus on verification of the final product only. The double check by two pharmacists outside the cleanroom also eliminated the backlog of products waiting for a second check by allowing the inside pharmacist to focus on checking the prepared product against the label. In addition, we implemented a more intuitive technician workflow, wherein each technician prepares only one drug in a regimen at a time, even if a patient has a multidrug regimen.
These improvements have resulted in a 57% reduction in turnaround time from baseline measurements taken 19 months ago, to an average turnaround time of 26 minutes.
PP&P: How can pharmacy and nursing staff work together to mitigate exposure risk?
UNC Hospitals: The most successful way to mitigate risk is to foster an environment of open communication, collaboration, and trust between pharmacy and nursing personnel. A safe environment for employees and patients results when both departments put patients’ and the hospital’s needs above the interests of individual departments. At UNC, an oncology safety committee, comprised of representatives from pharmacy, nursing, and physicians, meets monthly to identify and resolve safety and practice concerns. Medication variance reports are reviewed and discussed non-punitively to identify system solutions; these reports also help identify and resolve potential workarounds in the system. When policies need to be updated, the safety committee makes recommendations to the oncology P&T subcommittee for approval; once approved, staff is educated about the changes before implementation.
Cooperation between pharmacy and nursing improves safety and workflow for both departments. For example, collaborating with nursing colleagues during our recent implementation of the electronic medication administration record (eMAR) presented opportunities to streamline pharmacist order entry of chemotherapy. We identified that variation in the way pharmacy entered an order—while acceptable in the pharmacy system—translated differently to nursing. One-time-only orders can be entered two ways into the pharmacy system: the first allows the nurse to administer a medication when they are ready to start a new drug, and the order stays on the eMAR for 24 hours; the second option limits nurses to give the dose at the specific time assigned by pharmacy. Working together with nursing, we identified the safest and most efficient way to enter and administer the order, and standardized that method consistently. The approach decided upon depends on the preparation. For first doses in a regimen given only one time (eg, rituximab), the order stays on the eMAR for 24 hours (the first option). If the patient is receiving an intrathecal medication that is only going to be given on day five of the regimen, the second option is chosen.
While practice change is best instilled through multidisciplinary efforts, pharmacists are nonetheless responsible for maintaining oversight of the entire medication-use process, including drug administration. Pharmacists’ comprehensive understanding of the medication-use process positions us to lead the effort in implementing safe practices.
PP&P: How should a plan be developed for medical surveillance of personnel handling hazardous drugs?
UNC Hospitals: When considering a medical surveillance plan, pharmacy must decide what method best corresponds with the needs of the hospital: routine- or incident-based medical surveillance. Incident-based surveillance is prompted only when hospital personnel are inappropriately exposed to a hazardous drug, most commonly from an accidental spill. Exposed personnel are monitored by the hospital’s epidemiology department or designee from the time of the incident forward. In order to be successful with this approach, personnel must undergo training and competency testing prior to preparing and handling hazardous drugs without direct training supervision. They also need to be diligent in reporting exposures. A benefit of incident-based medical surveillance is that it minimizes expense and employee burden. Routine surveillance occurs on a scheduled basis, usually annually, and includes laboratory and provider appointments for testing. This is a proactive approach, but increases testing expense and labor hours. No data exists to support one surveillance method over the other, but either routine- or incident-based medical surveillance should occur. Our organization currently uses the incident-based approach for medical surveillance, as this was determined to be the most optimal method for our employees. (See SIDEBAR 2. NIOSH’s Components of a Medical Surveillance Program.)
An additional recommendation is to monitor routine surface sampling results for hazardous drugs. While technically not considered medical surveillance, surface monitoring can be used as a marker to determine potential hazardous drug exposure risk for employees. Should repeated tests document elevated levels of contamination, practice and education improvements are required to reduce employee exposure risk.
