Infection Control and Patient Safety Basics

What the work looks like

Healthcare workers are the primary vector for healthcare-associated infections (HAIs). CDC guidelines, OSHA bloodborne pathogen rules, and state health department requirements all converge on the same daily habits: hand hygiene, appropriate PPE, safe sharps handling, and honest reporting of exposures. Orientation at any hospital, nursing home, or agency will hammer these points before you see a patient.

Safety and tools

Hand hygiene comes first. Use alcohol-based hand rub for 20 seconds when hands are not visibly soiled; soap and water for 40 to 60 seconds when they are, after using the bathroom, and before eating. The WHO "5 Moments for Hand Hygiene" are: before touching a patient, before a clean or aseptic procedure, after body-fluid exposure risk, after touching a patient, and after touching patient surroundings.

Standard precautions apply to every patient: gloves for body-fluid contact, gowns and face protection when splash is possible. Transmission-based precautions add on:

• Contact precautions (MRSA, C. diff): gown and gloves in the room. Use soap and water after C. diff, not alcohol rub.
• Droplet precautions (flu, pertussis): surgical mask within 3 to 6 feet.
• Airborne precautions (TB, measles, COVID in some protocols): N95 respirator with annual fit test, negative-pressure room.

Safe sharps handling: never recap a needle, activate the safety feature immediately after use, dispose in an approved sharps container that is below the three-quarters-full line. Report any needle stick to your supervisor within the shift so post-exposure prophylaxis can start.

Patient-identification safety: always check two identifiers (name and date of birth, or name and medical record number) before any procedure, medication, or specimen collection. Time-out before any invasive task.

Tools: the hand-rub dispenser, a supply of gloves in multiple sizes, isolation carts outside patient rooms, sharps containers at point of use, and your badge (many hospitals track hand-hygiene compliance electronically through badge readers).

Your first exercise

Watch a CDC-produced video on donning and doffing PPE and practice the sequence with household items (glasses, trash bag as a gown, dish gloves). The donning order is gown, mask, goggles, gloves. Doffing is gloves, goggles, gown, mask. Getting the sequence wrong is how contamination spreads.
