1 Foundations of Healthcare Infection Prevention and Safety

Why prevention and safety matter

Healthcare workers, patients, and visitors share spaces and equipment and may encounter infectious agents and other hazards. Infection prevention interrupts the ways germs spread, workplace safety reduces harm to workers, and patient-safety practices reduce preventable injury during care. These responsibilities apply across healthcare settings, not only hospitals.

Core infection-prevention practices

Standard Precautions are the baseline for every patient, whether or not an infection is known or suspected. Choose measures according to the task and anticipated exposure. Core practices include Hand hygiene, appropriate PPE, respiratory hygiene, safe injections, environmental cleaning, and safe handling and reprocessing of equipment.

Perform Hand hygiene before touching a patient and before an aseptic task; after patient or environmental contact; after contact with blood or body fluids; and after removing gloves. Alcohol-based hand rub is appropriate for most clinical situations, while soap and water should be used when hands are visibly soiled. Gloves do not replace hand hygiene.

Assess the task and choose PPE that matches the expected exposure. Gloves protect hands, gowns protect clothing and skin, and masks, respirators, goggles, or face shields protect respiratory and facial surfaces as indicated. Follow the facility-approved sequence for putting on and removing PPE to avoid contaminating yourself or your surroundings.

Add Transmission-Based Precautions to Standard Precautions when a patient's suspected or confirmed infection requires additional controls. Contact, droplet, or airborne precautions may require specific PPE, room placement, and equipment practices. Follow current organism-specific and facility guidance.

Follow approved procedures to clean and disinfect surfaces and reusable devices between patients. Use aseptic technique and safe injection practices. Never reuse a syringe or needle for another patient, even if the needle is changed.

For example, before dressing a wound, perform Hand hygiene and assess the likelihood of contact with drainage. Wear gloves, add a gown or eye protection if splashing is possible, use aseptic technique, dispose of waste safely, clean reusable equipment, and perform Hand hygiene after removing gloves.

Workplace hazards and exposure response

Healthcare workplaces may involve biological hazards, needlesticks, chemical or drug exposures, respiratory hazards, lifting injuries, slips and falls, violence, and radiation or laboratory hazards. Workers should follow training and procedures, use available controls, keep walkways clear, report unsafe conditions, and ask for assistance or equipment when a task cannot be performed safely.

The Bloodborne Pathogens Standard applies to workers with reasonably anticipated occupational exposure to blood or other potentially infectious materials. Employers must maintain an Exposure control plan and use appropriate controls, training, PPE, and recordkeeping. Engineering and work-practice controls are primary ways to reduce exposure; examples include safer sharps devices and immediate disposal in appropriate sharps containers.

If a needlestick, splash, or other possible exposure occurs, immediately wash affected skin with soap and water or flush affected mucous membranes with water. Then report the incident and seek prompt medical evaluation under the facility's procedure. OSHA requires employers to make confidential post-exposure evaluation and follow-up available. Timely reporting helps care begin without delay.

Patient safety in daily care

Reliable routines and clear communication support patient safety. Follow facility procedures for confirming identity, communicating important changes, administering medications, preventing falls, handling equipment, and escalating urgent concerns. Check that the environment is safe, including clear pathways, dry floors, and needed items within reach, and report hazards or near misses.

Incident reporting helps organizations identify patterns and improve systems. Follow local policy and protect patient confidentiality when reporting. Infection prevention is also part of patient safety: recognize signs that may require isolation, promptly notify the appropriate team, follow posted precautions, and avoid transferring contamination between patients or care areas.

Patients and families can be invited to participate in safety practices, for example, by asking whether staff have cleaned their hands before care.

Roles and regulatory responsibilities

Healthcare workers follow infection-prevention and safety procedures, use equipment correctly, complete required training, report exposures and hazards promptly, and work within their training and role.

Employers and healthcare organizations provide a safe work environment, appropriate supplies and PPE, job-specific education, exposure-response processes, and systems for monitoring and improving practice. Personnel should receive training before performing duties and periodic refresher training.

Infection preventionists and occupational-health staff support policies, education, surveillance, audits, exposure management, and communication with clinical teams and leadership. Responsibilities vary by setting and applicable rules.

CDC issues public-health guidance and recommendations; it is not the workplace-safety enforcement agency. OSHA sets and enforces applicable federal workplace-safety requirements, including the Bloodborne Pathogens Standard. State-plan states may administer OSHA-approved workplace-safety programs. CMS sets participation requirements for covered healthcare programs; hospitals must maintain infection-prevention and control and antibiotic-stewardship programs under 42 CFR § 482.42. State and local laws and facility policies may add requirements.

Putting prevention into practice

Use Standard Precautions for every patient and add Transmission-Based Precautions when indicated. Match PPE to the task, perform Hand hygiene at key moments, use safe sharps and injection practices, and clean equipment appropriately. Identify hazards, report possible exposures immediately, and follow facility procedures for patient safety. Workers, employers, infection-prevention teams, and regulators have distinct but complementary roles in preventing harm.
