-
3 levels of prevention
- Primary prevention
- Secondary prevention
- Tertiary prevention
-
Primary Prevention
- True prevention
- example: immunization
-
Secondary prevention
- People who are experincing health problems or illnesses and who are at risk for developing complications or worsening conditions.
- Examples: education, adequate treatment to arrest disease process and prevent further complications.
-
Tertiary prevention
- Has the disease or sickness, disability
- Examples: doing whats possible to correct the problem or try to make it less. (highest level of functioning is goal)
-
Acute Illness
- Usually short term and severe.
- Examples: surgery
-
Chronic Illness
- usually lasts longer than 6 months. Patients fluctuate between maximal functioning and serious health relapses that are sometimes life threatening.
- Example: Diabetic
-
Colonization
The presence and growth of microorganisms within ahost but without tissue invasion or damage.
-
-
Communicable
- infection disease transmitted directly from one person to another.
- Examples: T.B.
-
Symptomatic
- pathogens multiply and cause clinical signs and symptoms
- (Signs)
-
Asymptomatic
- clinical signs and symptoms are not pressent.
- (No Signs)
-
Chain of Infection
- Transmission
- Portal of entry
- Host susceptibility
- infectious agent
- Reservoir
- Portal of exit
-
Modes of Transmission
- There are 4 kinds of modes:
- Contact
- Airborne
- Vehicles
- Vector
-
Contact (Modes of Transmission)
- Direct: Person to person or physical contact between source and susceptible host.
- Indirect: Personal contact of susceptible host with contaminated inanimate objects
- Droplet: Large particles that travel up to 3 feet and come in contact with susceptible host.
-
Airborne (Modes of Transmission)
- Droplet nuclei, residue or evaporated droplets suspended in air.
- example from coughing, sneezing, talking
-
Vehicles (Modes of Transmission)
- Contaminated items
- water
- drugs, solutions
- blood
- food
-
Vector (Modes of Transmission)
- External mechanical transfers (flies)
- Internal transmission such as with parasitic conditions between vecotr and host.
- examples: Mosquito, Louse, tick, Flea
-
Suprainfection
- The over use of antibiotics.
- can destroy normal flora.
-
health care-acquired infection
A person gets a disease due to the care provider.
-
-
Aseptic technique
an effort to keep the patient as free from exposure to infection causing pathogens as possible.
-
Asepsis
means the absence of disease producing micoorganisms.
-
Medical Asepsis (one of two type of asepsis)
- clean techniques, includes procedures used to reduce the number of and prevent the spread of microorganisms.
- Example: Hand Hygiene, Barrier techniques, and routine environmental cleaning.
-
Surgical Asepsis (one of two type of asepsis)
- Sterile technique, includes procedures to eliminate all microorganisms from an area.
- Examples: Sterilization destroys all microorganisms and their spores.
-
What is the acronym ADPTE stand for
- A=Assesment
- D=Diagnosis (non medical)
- P=Planning
- I=Implement
- E=Evaluate
