Infection Prevention & Control
Subject Summary
The public overview below follows the supplied PhysioVeda Academics subject summary.
Infection prevention and control (IPC) reduces the transmission of infectious agents in healthcare through hand hygiene, asepsis, appropriate protective equipment, environmental decontamination and safe care pathways.
Standard Precautions apply during care of every patient. Transmission-Based Precautions add targeted measures when infection route or clinical presentation creates additional risk.
The same IPC principles must be adapted for rehabilitation, dental and oral healthcare, imaging and laboratory practice, maternity and pediatric care, and community or home visits.
This study summary follows the uploaded 29-topic PhysioVeda Academics outline in its original order. The explanatory text, examples and high-yield tables are educational synthesis, not quotations from the outline; apply local IPC policies and device manufacturers’ instructions in practice.
Whole-subject high-yield numbers and concepts
Use these supplied values and key facts for quick whole-subject revision.
| Universal starting point | Standard Precautions apply to every patient, every setting and every encounter |
| Extra measures | Add contact, droplet and/or airborne measures according to transmission risk |
| Chain of infection | Infectious agent → reservoir → portal of exit → transmission → portal of entry → susceptible host |
| WHO hand-hygiene moments | Before patient contact; before aseptic task; after body-fluid risk; after patient contact; after patient surroundings |
| Spaulding classes | Critical → sterilize; semicritical → at least high-level disinfect; noncritical → usually low-level disinfect |
| PPE principle | Match PPE to exposure risk; glove use never substitutes for hand hygiene |
| Reprocessing sequence | Point-of-use handling → cleaning → appropriate disinfection/sterilization → safe storage |
| Needlestick response | Immediate first aid → report → urgent exposure assessment → indicated follow-up |
| Case decision rule | Identify task, transmission route, patient vulnerability, environment, and local IPC policy |
| Improvement loop | Surveillance → audit → feedback → corrective action → re-audit |
