What are they and why do they always apply?
Standard precautions are the foundation of infection control in healthcare. They apply to all patients because the presence of infectious agents may be unknown. The selection of practices and equipment depends on the anticipated interaction and the potential for contact with biological material, not solely on the recorded diagnosis.
Applying these procedures systematically reduces improvised decisions. The procedure must be readily available where care is provided and compatible with the actual conditions of the service. Correct instructions lose their effectiveness when necessary equipment is unavailable, appropriate containers are lacking, or organizational requirements force frequent interruptions to a technique.
Hand hygiene and use of gloves
Hand hygiene is of paramount importance and must be integrated into the care sequence according to the center’s current protocols. Gloves are used when anticipated exposure requires them, changed between situations that demand it, and removed in a way that avoids contaminating the skin and the surrounding environment. They do not replace hand hygiene.
Training should explain both the correct use and common errors. Touching keyboards, phones, or clean equipment with contaminated gloves can spread contamination. It’s advisable to map the entire workflow to strategically place supplies and disposal points to facilitate safe practices, including during urgent tasks and staff changes.
Equipment according to the planned exposure
The possibility of splashes guides the selection of eye, face, skin, and clothing protection. Eye and face protection must allow the task to be performed and be properly combined with other equipment. Donning, doffing, disposal, or reprocessing require specific instructions to prevent the equipment itself from becoming a source of contact.
A medical mask and respiratory protective equipment have different functions. When the situation requires protection against inhalation, the corresponding criteria and protocols must be applied. The choice is not resolved by using the same set of PPE for every activity, but rather by identifying the exposure and the additional measures needed.
Sharps, samples and materials
Preventing injuries from sharps requires appropriate devices, containers, and procedures. Unnecessary handling should be avoided, and the disposal of used materials should be carried out within a secure circuit. The availability of safety systems must be accompanied by practical training and verification of their use.
The handling of samples, instruments, and textiles must also prevent dispersion and contact. Clean and contaminated materials must be separated, containers and routes defined, and appropriate cleaning, disinfection, or sterilization procedures applied. Cleaning, laundry, and transport personnel are part of this process and require information tailored to their specific tasks.
Relationship with additional precautions
Standard precautions remain necessary when transmission-based measures are added. These latter measures are implemented for certain known or suspected infections and may include specific actions against contact, droplet, or airborne transmission, in accordance with applicable clinical and public health protocols.
The necessary information must reach those involved in care without disseminating unnecessary clinical data. An internal transfer, an examination, or the intervention of an external service can introduce disruptions. It is helpful to define who transmits preventive instructions, when, and how to confirm that the necessary resources will be available at the destination.
Organization and incident response
The center’s management must provide resources, training, and coordination between prevention, infection control, and healthcare staff. Workplace vaccination and health surveillance complement work practices. Neither of these measures allows for abandoning barriers against exposure nor assuming that everyone has the same level of protection.
In the event of accidental contact, the center’s established procedure must be activated immediately, and timely medical assessment must be provided. The notification process needs to be simple and readily available, even during night shifts or holidays. The subsequent investigation should examine both material and organizational factors, rather than simply focusing on a possible distraction on the part of the affected person.
Practical example
In a treatment area, professionals have found that they must carry used materials around because the disposal containers are not located at the point of care. A review of the procedure also reveals that protective eyewear is stored in a shared cabinet that is difficult to access during procedures.
The service reorganizes supplies and procedures, conducts supervised practice, and verifies functionality across multiple shifts. Replenishment is checked, and a fast-track system is established for reporting material shortages. The improvement is evaluated based on the actual feasibility of following the safe sequence, in addition to reviewing any recorded incidents.
How to verify its implementation
Observing practices, equipment availability, training quality, and incident response provides complementary information. The results should be used to address barriers and explain improvements. An aggregated percentage can mask important differences between units or shifts and should be analyzed within context.
Common mistakes include applying measures only to patients with known infections, considering gloves as universal protection, or reducing prevention to a poster. Standard precautions function as part of the healthcare organization: they must be applicable during the task, reviewed with staff, and maintained when workload increases.
