Damage
Why are we concerned about exposure in
healthcare workers?
Based on long term side effects in treated
patients, it became obvious that there are risks
for the occupational exposed
Patients receive concentrated doses of a limited
number of agents for a defined period of time.
Healthcare workers are exposed to small doses
of a broad range of hazardous medications over
decades
Secondary Malignancies in Chemotherapy Treated
Cancer PATIENTS
 A new cancer that occurs in
a patient after treatment
with chemotherapy or
radiation for a different
cancer
 May occur in months to
years after treatment
 Considered side effect /
caused by the initial cancer
treatment
 Easily treated:
 skin cancers (basal cell or
squamous cell carcinoma)
 Extremely serious:
 Acute Leukemia (patient will
die without immediate
hospitalization and very
strong chemotherapy)
 Other cancers:
 Non-Hodgkin’s Lymphoma
 Myelodysplastic Syndrome
(aka pre-leukemia)
Example of Risk to the Patients
Breast Cancer Treatment
 Secondary Cancers
with doxorubcin based
treatment


10 years – 3.8%
15 years – 7%
 Secondary Cancers
 With radiation - 3.4%
 Chemo only – 4.7%
Hodgkin’s Disease
 Secondary Cancers


20 years – 10 %
30 years – 26 %
 6.5 times the normal
person’s risk or dying
from another cancer
 Chemo while < 21 yo
– 14 fold increase in
death from secondary
cancer

How Does the Malignancy Risk relate to
Healthcare Workers?
Incidence is related to:
Cumulative dose
Dose Intensity
Individuals innate DNA repair capacity
Therapy induced Myelodysplastic syndrome (t-MDS) and
therapy induced Acute Myelogenous Leukemia (t-AML)
related to specific mutations
Can this data be extrapolated to Healthcare worker

Relationship of cancer occurrence in HCW
exposures to antineoplastic HDs (NIOSH)
Cancer mortality study of HCWs in 24 states [Petralia et al. 1999]
 Nurses: 30% ↑ mortality due to liver cancer and myeloid
leukemia among nurses
 Pharmacists: two-fold ↑ of mortality from myeloid leukemia
in pharmacists
Occupation and Leukemia Study in two mid-western U.S.
states (Blair et al. 2001)
 Nursing and healthcare workers: ↑ in Leukemia
Danish Female Pharmacy Technicians: ↑ risk of nonmelanoma skin cancer and non-Hodgkin’s lymphomas [Hansen
and Olsen 1994].
Cancer incidence in registered nurses
 56,213 Female RNs - professional regulatory body
compared to Canadian cancer registries.
 Worked in cancer center or oncology nursing unit:
↑ risk of breast cancer (RR = 1.83; CI = 1.03 - 3.23)
 RNs with highest weighted durations of exposure to
antineoplastic drugs:
↑ risk of rectal cancer (RR = 1.87, CI = 1.07 - 3.29)
 No statistically significant increased risks of leukemia,
other cancers
Cancer Risk Assessment
 Mathematical Analysis based on:
 Patient Exposure to CP and Secondary Cancers
 Healthcare worker Urinary Excretion Data
 Rodent Models to test Acute and Chronic Exposures and
Secondary Cancers
 Healthcare worker with CP exposure conservative
estimates – additional 1.4 to 10 cases of cancer per 1
million workers per year.
 New data with 5 times greater daily urinary CP
excretion
 Extrapolation of data could yield an additional 7 to
50 additional cancer cases per million healthcare
workers each year.

Immunomodulators
Adalimumab (Humira ) & Etanercept (Enbrel)

Lymphoma (3X more than the general populations) (median of
30 months) and other malignancies, some fatal, reported in
children, adolescents and adults taking TNF blockers
Tacrolimus (Prograf) & Cyclosporin (Sandimmune,
Neoral)


at increased risk of developing lymphomas and other
malignancies, particularly of the skin The risk appears to be
related to the intensity and duration of immunosuppression
rather than to the use of any specific agent.
Post transplant lymphoproliferative disorder (PTLD) has been
reported in immunosuppressed organ transplant recipients.

Pharmaceutical Dust Exposure
 Water soluble can be absorbed across mucous
membranes
 Particles <0.02 microns
 Can remain suspended in air for several hours
 After using Compressed air to clean canisters,
> hour passed before the small particles
produced were reduced to the pre-cleaning level

 Lisinopril – air samples exceeded the manufacturer
recommended Occupational Exposure Limit (OEL 1
ug/m3)
 Levothyroxine – air samples when cleaning and
refilling canisters (OEL < 1ug/m3)

hazardous medications
Consider use of hood when refilling canisters
Clean machines with HEPA filtered vaccum and change
filter often per manufacturer guidelines
Do not use compressed air to clean canisters
Wear nitrile gloves when handling pharmaceuticals
Clean pharmacy surfaces with alcohol based cleaner
every 2-4 hours
Wash hands before eating, drinking or using tobacco
products
So now that we know the risks what
can we do to minimize HD exposure
to “as low as reasonably achievable”

Compliance with Devices is Important
 Uncontrolled trial in a active hospital
 Trialed one CSTD, then trialed a different CSTD.
 Decontamination products were employed in the hospital
 Wipe Studies Preformed by commercial company
 Both Products considered statistically equal
 Both resulted in undetectable levels of CP, FU, MTX
 Compliance with one system was poor
 System with full compliance lead to 70% lower levels
of exposure to the HDs analyzed for
Lepford 2010
Survey from Pharmacy Purchasing and Products Magazine April 2015
Q: Which of the statements is true with regards to
the role of Alcohol and HD contamination
A. Alcohol is an effective agent for decontamination
of hazardous drugs
B. Alcohol is not effective for decontamination of
hazardous drugs
C. Alcohol solubilize hazardous drugs and can spread
contamination
D. A and C
D. B and C
Decontamination
 Isopropyl for disinfecting a BSC will not deactivate any
hazardous drugs and may result in the spread of
contamination. (ASHP)
 Alkaline Soap – traditional soap and water will liberate
the chemicals from the surface and the water will wash
them away
 Sodium Hypochlorite (Bleach) is a strong oxidizer shown
to deactivate many hazardous drugs (MDMS)
Decontamination
 Sodium Hypochlorite
 Sodium Thiosulfate
 Surface Safe (2 step)
 Sodium Hypochlorite + Surfacant
 Sodium thiosulfate
 HD Clean (2 Step)
 Combination of 4 ammonium chloride compounds
 Neutralizer
 Magnesium oxide + Titanium dioxide
 Fast Act
 Baby Wipes?
Spill Clean Up Procedures
Liquid Spill
Powder/ Dry Spill
 Cover with absorbent
 Cover with absorbent
Towels
 Adorn PPE
 Alert Others of Spill
Towels
 Pour water over towels
to get powder into
solution
 Adorn PPE
 Alert Others of Spill
Respirators must be used when cleaning spills.
Disposal and Decontamination
 All disposable protective clothing as well as any
disposable materials used while handling oral
chemotherapeutic agents should be disposed of as
cytotoxic waste according to the local waste disposal
regulatory guidelines.
 All nondisposable materials exposed to
chemotherapeutic agents including counting trays,
tools, surfaces, etc should be washed or
decontaminated* thoroughly after use.
Administrative Controls
Administration Concerns
 No direct priming of chemotherapy
 Do not remove tubing from an IV containing
chemotherapy
 Be aware of surface contamination
 Wear appropriate PPE for administration
 Ensure excellent hand washing after removing PPE
 Communicate safe handling information
Employee Training and Competency
 Orientation Programs and Routine training courses
“didactic overview of hazardous drugs, including mutagenic,
teratogenic, and carcinogenic properties”.
Competency assessments
Spill Clean-up
Trained and competent to treat individuals accidentally exposed
Hazard Communication
 All risk personnel (including support staff) shall confirm in writing
that they understand the risks of working with hazardous
medications.
Custodial staff involved in cleaning activities and waste removal
should have appropriate training on how to protect themselves and
prevent contamination. This should be documented, initially and
annually thereafter.

Medical Surveillance
 “Workers who are potentially exposed to chemical
hazards should be monitored in a systematic
program of medical surveillance intended to prevent
occupational injury and disease.”- ASHP
 NIOSH 2012 Alert: Medical Surveillance for Health
Care Workers Exposed to Hazardous Drugs
considers this mandatory, but provides little detail
 OSHA has a very detailed section on this OSHA:
Controlling Occupational Exposure to Hazardous
Medications
 USP 800 comprehensive Medical Surveillance.
Monitoring Environmental Contamination
 OSHA - environmental surveillance is mandatory
 USP 797 – “recommended” initially and at least every 6
months.

Currently a strong recommendation due to lack of standardized
analysis and established acceptable levels.
 USP 800: “To ensure containment of HDs,
environmental wipe sampling to detect
uncontained HDs should be performed routinely
(e.g., initially as a benchmark and at least every 6
months, or more often as needed, to verify
containment).”
Environmental Monitoring is Not Hard
 Commercially Available Do-It-Yourself kits
 Identify the appropriate surfaces
 Read instructions and collect samples
 Mail samples to lab
 One wipe sample can be tested for presence of multiple drugs
 Electronic Reports provide comparisons with other facilities
 Use as a bench mark and then get Safer!!!!!
 ChemoGlo
 Tests for 5 drugs with option of one additional drug
 Bureau Veritas – Chemo Alert
 Can test for 45 compounds, customize panel of 9
Example Report for HD Surface Testing
Caring for Patients Receiving HDs
 Cyclophosphamide detected on:


linens, wash clothes
Test pads attached to RNs bodies
 Cyclophosphamide most
concentrated on RNs Hands:



Gloves had high incidence of
contamination
Hands were swabbed after RN removed
gloves
Skin contamination most frequently
detected after handling urine
Fransman 2005
Post-Administration Concerns
 Wear appropriate PPE when handling bodily fluids of
patient treated with chemotherapy (for at least 48 hours
and up to 7 days for some medications)
 Post Signs that “patient has received chemotherapy with
the last 48 hours”
 Minimize handling of HD contaminated urine
Body Waste Disposal – no current research
 Double flushing
 Bleach in the toilet – appearing more frequently
 Contaminated Body Waste Disposal Systems

Hazardous Drugs in Body Fluids
 Emesis * IV MTX enters emesis
 Seminal Fluid * cyclophosphamide in rats
 Effusions (pleural or peritoneal)
 PPE for administration = PPE for handling patient
body fluids (add splash shield where appropriate)
 High incidence of non-compliance related to PPE for
handling body fluids
Medical Surveillance
Per Proposed USP Chapter 800:
“The goal of medical surveillance is to minimize adverse health
effects in workers exposed to HDs.
“A medical surveillance program involves collecting and
interpreting data to detect changes in the health status of
working populations potentially exposed to hazardous
substances.
“Employers shall ensure that healthcare workers who are
exposed to HDs are routinely monitored as part of a medical
surveillance program.”
Developmental and Reproductive Effects
NIOSH Meta Analysis
 Increased risk of miscarriage
 Increased risk of congenital malformations
 Increased risk of sub-fertility (Women and
Men)
 Concern for non-antineoplastic HDs, that exhibit
adverse reproductive effects in treated patients,
may also be problematic as occupational risks.

Sutent –In rats, the
concentration in
breast milk found
to be 12x greater
than the
concentration in
blood
Developing fetus and newborns up to the age of
six months more sensitive to chemical toxicity
 Immature Detoxification and Excretion pathways
 Toxicants may be present in higher concentrations in the
blood for longer periods
 Fetus is often more susceptible than the mother to toxicants
 Placenta is poorly effective against lipophilic chemicals and
low-molecular-weight molecules
 “Exposure to chemicals and radiation in utero and early in
life can disproportionally increase the occurrence of
childhood cancer compared with exposures that occur later
in life”

ORAL CHEMOTHERAPY
ORAL CHEMOTHERAPY
 1.5% of all Insured receive anti-cancer
treatment in a given year
 Of those patients 16% receive their chemotherapy
orally (2010 data).
 Of the 400 new anti-neoplastics in development,
25% are orally administered
 Currently no specific competency requirements for
individuals authorized to administer oral
chemotherapy vs. other oral medications
2013 Updated ASCO / ONS Chemotherapy Administration Standards
Non-Oncology Uses of Common Chemotherapy
 Cyclophosphamide
 Idiopathic Thrombocytopenia
 Multiple Sclerosis
 Rheumatoid arthritis
 Sarcoidosis
 Scleroderma
 Lupus
 Solid Organ Transplant
 Vasculitis
 Mercaptopurine

Non-Liquid Hazardous Drugs
 HDs in solid dosage forms pose a health risk to employees
 Pressed powder, uncoated tablets liberate dust particles



surface contamination
airborn drug dust directly inhaled by employees
Common medications include:
 cyclophosphamide, methotrexate, alkeran, 6mercaptopurine
 Dosage Form Risk

non-coated tablets > Coated tablets > Capsules
 Gel-caps or coated tablets are unlikely to produce dust unless broken in
handling, but still pose a risk for surface contamination
 Use caution when tilting stock pill bottles and dust liberated in
production and transport often accumulates in the bottle of bottles.

Inform other health care professionals
that you are on oral chemotherapy (eg,
surgeons and dentists).
Minimize the number of individuals
coming in contact with the cytotoxic
medications.
Wash the patient’s clothes and bed
linen separately from other items.
Double-flush the toilet after use, during
use of and 4 to 7 d after discontinuing
oral chemotherapy.
It is recommended that caregivers wear
gloves at all times while handling oral
chemotherapeutic agents as well as
contaminated items in order to
minimize risk of exposure


Leave medication in open areas, near
sources of water, direct sunlight, or
where they can be accessed by
children or pets.
Store medications in the areas where
food or drinks are stored or consumed.
Crush, break, or chew tablets.
Double-up on doses, unless instructed
by a health care professional.
Assume that oral chemotherapy is
safer than intravenous chemotherapy.
Skip doses unless instructed by your
physician
Conclusion
The goal is to decrease environmental
contamination to a level “as low as
reasonably achievable” (ALARA)
through education, safe handling
practices and employer support.
