Pre‐procedural considerations

Equipment

It is vital for healthcare personnel to use PPE while handling cytotoxic drugs. This includes consideration of the environment. The most effective means of minimizing the hazard is to arrange for all cytotoxic drugs to be prepared on a named patient basis by trained pharmacy staff in a specially equipped area. Chemotherapy should be reconstituted in a vertical class II or III biological safety cabinet with laminar flow or an isolator if drugs are prepared on the ward (Ferguson and Wright [74], Weinstein and Hagle [265], Wilkes [268]). Cabinets should be situated in a dedicated area with access restricted to trained or supervised personnel.
There is no doubt that the existence of a formal hospital policy for handling cytotoxic drugs has a positive influence on the use of PPE. Minimizing occupational exposure to hazardous drugs, and therefore reducing health risks for personnel, can only be achieved by strict adherence to policies and procedures regarding the safe handling of cytotoxic drugs (Polovich et al. [194]). Protective clothing should always be worn during all types of cytotoxic drug handling (HSE [104]). There are minimum requirements for the type and degree of protective clothing which are based on possible exposure and type of environment. However, even though cytotoxic exposure is known to be harmful, many healthcare workers do not comply with some PPE precautions. Studies have demonstrated that not all PPE is worn, with approximately 95% of healthcare workers reporting wearing gloves but less than 50% wearing gowns while administering chemotherapy (Polovich and Clark [193]). A study carried out by Polovich and Clark in 2012 demonstrated that circumstances in the workplace such as a high volume of patients per day were the reason that nurses did not wear PPE. Furthermore, managers cited that a lack of time was also a reason why nurses may not use PPE (Polovich and Clark [193]).

Gloves

Disposable gloves should be worn at all times and appear to be the only type of protective clothing that most practitioners consistently wear when handling cytotoxic drugs. Polovich and Clark ([193]) state that 95% of nurses routinely wear gloves when handling hazardous materials. No type of glove is completely impermeable to every cytotoxic agent and there is no consensus as to which glove material offers the best protection (Weinstein and Hagle [265]). The key points to consider when selecting gloves are the main factors that affect permeation rates, including glove thickness, lipophilicity, the nature of the solvent in which the cytotoxic drug is dissolved and glove material composition (Ferguson and Wright [74], Polovich et al. [194]). Using poor‐quality low‐cost gloves is neither safe nor cost‐effective. The risk of allergic reactions to latex and powdered medical gloves has been well documented in recent years. The Health and Safety Executive (HSE [105]) has issued advice on the use of these types of gloves. Powder‐free gloves should be used for handling cytotoxic drugs and should be inspected for any defects before use. Gloves should be changed after 30 minutes during each work session or at the end of a work session and immediately if contaminated with cytotoxic agent or punctured (Polovich [192]). The use of gloves made of other material, such as nitrile, provides protection when dealing with a cytotoxic spill. Double gloving is recommended when reconstituting cytotoxic drugs (Polovich et al. [194], Polovich [192], Weinstein and Hagle [265]).

Gowns

The literature supports the use of a disposable gown for both reconstitution and administration (HSE [104]). It has been suggested that a long‐sleeved, non‐absorbent gown made of a low‐linting, low‐permeability material such as Tyvek is used (Ferguson and Wright [74], Weinstein and Hagle [265]). Gowns coated with polyethylene or vinyl offer the best protection (Polovich [192]). Gowns should have a solid front and a back closure as well as long sleeves and tight cuffs (Polovich et al. [194], Weinstein and Hagle [265]). Gowns are designed for single use only and should not be hung up or reapplied once removed (Polovich [192]). This will prevent drug contamination of the environment as well as the worker's clothing. Armlets and plastic aprons can be used as a substitute for long‐sleeved gowns during administration (HSE [104]).

Goggles

Goggles are used to protect the eyes from splashes and particles; they should fully cover the eyes of the handler. Goggles should meet BS EN 166 requirements and be worn whenever reconstituting chemotherapy where there is a possibility of splashing or dealing with a spill (Ferguson and Wright [74], LCA [138], Polovich [192]).

Masks

These should be worn whenever there is a possibility of inhalation or if the drug is being prepared in an uncontrolled environment. Masks should conform to BS EN standard. The key factor regarding respiratory protective equipment is that it fits well and is sealed properly to the wearer's face. A range of different sizes of disposable masks should be made available to healthcare workers (Ferguson and Wright [74]). A suitable dust mask or particulate respirator with a FFP2 or FFP3 filter should be used (LCA [138]).

Waste disposal

Sharps should be placed in a sharps bin compliant with waste management regulations to ensure incineration and to prevent laceration and/or inoculation during transit and disposal (DH [50]). The government guidance on safe management of healthcare waste (HTM) 07‐01, which includes cytotoxic and cytostatic waste advice, should inform local healthcare policy (DH [45]). Cytotoxic waste is segregated into purple‐lidded waste bins (DH [50]). Dry waste, intravenous administration sets and other contaminated material should be placed in the appropriate waste disposal bags. The practitioner should wear gloves and an apron when disposing of contaminated waste (DH 2012, Polovich et al. [194]).

Spillage

Spillage is when cytotoxic drugs are accidentally splashed, spilled or leaked onto a surface, equipment or a person's skin or mucous membranes. Procedure guideline 23.1 should be followed when managing a spillage. Prevention measures consist of careful connection of infusions using Luer‐Lok equipment to reduce risk of disconnection and spiking infusion bags flat in a plastic tray (never spike a hanging bag).
Procedure guideline 23.1
Uncontrolled exposure may lead to symptoms which may be attributed to the effects of harmful levels of cytotoxic drugs, for example headache, dizziness, eye or skin irritation.If this occurs it may be necessary to do the following:
  1. Take six‐monthly blood tests are taken, which include full blood count, urea and electrolytes and liver function tests.
  2. Perform six‐monthly urinalysis is performed to detect raised protein, presence of glucose, blood and bilirubin and any abnormal cytology.
If any abnormalities are present, the individual is referred to the occupational health doctor (Polovich [192])
Box 23.2
Cytotoxic health surveillance
The Health and Safety Executive (2016) recommends:
  • taking a detailed medical history of the individual
  • maintaining an exposure record
  • ensuring personal protective equipment is used
  • ensuring control measures are in place.
