Source: OSHA Technical Manual: Controlling Occupational Exposure to Hazardous Drugs US Department of Labor 1999 “Workers who are potentially exposed to chemical hazards should be monitored in systematic program of medical surveillance to prevent occupational injury and disease… The purpose of surveillance is to identify the earliest reversible biological effects so that exposure can be reduced or eliminated before the employee sustains irreversible damage” Medical Surveillance
Medical Surveillance For Who & Why… • To develop a standard that applies to all employees that support patient care services • Product preparation • Product administration & infusion • Acquisition transportation • Environmental service/housekeeping • Waste disposal • To identify biologic effects in anticipation that exposure will be reduced or eliminated [before an employee sustains irreversible damage or injury]
Medical Surveillance • NIOSH recommends (not a mandate) workers handling hazardous drugs be monitored • Medical history • Exposure history • Physical examination • Selected lab tests (complete blood count, reticulocyte count, or occult blood in urine) Source: NIOSH 117 document April 2007;www.cdc.gov/niosh/docs/wp-solutions/2007-117/NIOSH
Medical Surveillance Elements of a medical surveillance program • Reproductive and health questionnaires at hire and periodically • Laboratory work • Complete blood count, Urinalysis, Reticulocyte count, Transaminases (AST, ALT), Alkaline Phosphatase • Physical examination at hire and thereafter for abnormal findings on health questionnaire • Follow-up for those workers who have health changes or significant exposures • Tracking trends with questionnaires and sick-call
Medical Surveillance • NIOSH also suggests environmental sampling and/or biological monitoring when exposure is suspected • Some organizations considering urine testing for presence of chemotherapeutic agents
Environmental Monitoring(Wipe Testing) Measures the presence/release of the drug in the environment No information about uptake of the drug in the body of the worker No information about health-risk for the worker Biological Monitoring(Urine Testing) Assessment of uptake of the drug in the body of the worker Estimation of health-risk for the worker Environmental and Biological Monitoring
USP 797 Recommendation for Environmental Sampling • Suggests routine environmental sampling to detect uncontained hazardous drugs • Initial benchmark and every 6 months or more as needed • Surface wipe sampling of BSC or CACI and adjacent areas including the floor directly under the work area, counter tops, and patient care areas • Common marker drugs include cyclophosphamide, ifosfamide, methotrexate, and fluorouracil
USP 797 Recommendation for Environmental Sampling • If any measurable contamination is found, practitioners shall make the decision to identify, document and contain the cause • Action may include retraining, thorough cleaning, and improving engineering controls • USP notes that cyclophosphamide levels greater than1.0 ng/cm2 has been found to cause human uptake
Sessink Stride Risk Level Model • Based on predictive model for additional cancer cases per million workers based on cyclophosphamide urine levels • Stride risk level is 1 extra cancer case a year per million workers • Prohibitory risk level is 100 extra cancer cases a year per million workers Source: Dr. Paul Sessink Exposure Control; 2008
Training on Handling of Hazardous Medications • ASHP (1990) and OSHA (1995) agencies must have a system for validating staff performance, and this must be documented • USP 797 revisions state all personnel who compound hazardous drugs shall be fully trained in the storage, handling and disposal of these drugs • Training must occur prior to preparing or handling hazardous CSPs & effectiveness must be verified by testing specific hazardous preparation techniques at least annually with results documented • Current MSDSs must be readily available in the areas hazardous drug preparation and administration Source: ASHP;Gullo, 1988:OSHA, 1990, 1995: USP 797 revisions (2007)
Training on Handling of Hazardous Medications Training must include at least: • Use of engineering controls including correct use of closed-system transfer devices • Use of PPE • Drug preparation • Drug Transport • Drug administration • Disposal of hazardous materials • Management of hazardous drug spills • Management of acute exposure
Training on Handling of Hazardous Medications Education Plan • Orientation to hazardous chemicals • Key contacts within the organization • Location of policies • Encourage employees to notify their physician of their possible occupational exposure to hazardous drugs • Educate employees of signs and symptoms • Based on the agents • Acute vs. chronic • Annual review of critical process and hazardous chemicals • Plan in place to educate on new chemicals
Training on Handling of Hazardous Medications Storage and Compounding • Evaluation of work environment and equipment • Policy & Procedures • Delineation of hazardous materials • Develop list with Safety departments • Labeling, storage, personnel issues, spill control • Education, preparation, administration, disposal • Evaluation of workspace • Ventilated cabinets • Use of equipment or devices to minimize exposure • Personal Protective Equipment (PPE) • Closed-system drug transfer device (CSTD) Source: Massoomi, 2007
