Standard Precautions for Infection Control in Hospitals.pptxanjalatchi
Standard precautions are a set of infection control practices used to prevent transmission of diseases that can be acquired by contact with blood, body fluids, non-intact skin (including rashes), and mucous membranes.
Aseptic strategy implies utilizing practices and methodology to keep pollution from pathogens. It includes applying the strictest standards to limit the danger of disease. Human services laborers utilize aseptic system in medical procedure rooms, facilities, outpatient care focuses, and other social insurance settings.

Aseptic strategy implies utilizing practices and methodology to keep pollution from pathogens. It includes applying the strictest standards to limit the danger of disease. Human services laborers utilize aseptic system in medical procedure rooms, facilities, outpatient care focuses, and other social insurance settings.
A. Standard Precautions-Standard precautions are to be followed for all patients, irrespective of their infection status.
These are to be used to avoid contact with blood, body fluids, secretions and excretions regardless of whether contaminated grossly with blood or not; non intact skin; and mucous membrane.
They are the basic level of infection control precautions which are to be used, as a minimum, in the care of all patients
Infection control measure to be undertaken by hospital- Use standard precaution for the care of all patients.
This general mandate is necessary because it is sometimes not known if the patient is colonized or infected with certain pathogenic microorganisms.
Barrier precautions reduce the need to handle sharps.
B. Transmission Precautions- The second tier condenses the disease-specific and categories approach to isolation into new transmission categories to be taken based on the route of transmission of organisms like contact precautions, airborne precautions, etc.
These precautions are designed for specific patients with highly transmissible pathogens

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

3. Florence Nightingale, Notes on
Hospitals, 1863
It may seem a strange
principle
to enunciate as the very
first requirement
of a hospital
that it do the sick no
harm
4. Learning Objectives
1. Recognize patient safety as an important nursing
responsibility in global health care systems.
2. Apply required knowledge in preventing and/or minimizing
infection.
3. Perform appropriate behaviors required to prevent health
care associated infections.
4. Demonstrate required competence to provide patients with
safe care.
5. Main types of infections
Urinary track infections
usually associated with
catheters
Surgical infections
Blood stream infections
associated with the use of
an intravascular device
Pneumonia associated
with ventilators
other sites
6. Health workers to be alert
Facility staff remain
alert for any patient
arriving with symptoms
of an active infection
(e.g., diarrhoea, rash, re
spiratory
symptoms, draining
wounds or skin lesions)
7. Global Infection Problems
According to WHO (2005),
On average, 8.7% of hospital patients suffer health
care-associated infections (HAI).
In developed countries: 5-10%
In developing countries:
Risk of HAI: 2-20 times higher
HAI may affect more than 25% of patients
At any one time, over 1.4 million people worldwide
suffer from infections acquired while in hospital.
8. Infection control in the
Hospitals
Infection control and
prevention uses a risk
management approach to
minimise or prevent the
transmission of infection.
Standard and additional
precautions principles and
practice are based on the
mode of transmission of an
infectious agent.

Host
Why Isolation?.. because transmission is
easier to control than the source / host!
10. Practice basic Protocols with
Universal Precautions
Standard precautions are work practices required for
the basic level of infection control. They include good
hygiene practices, particularly washing and drying
hands before and after patient contact, the use of
protective barriers which may include gloves, gowns,
plastic aprons, masks, eye shields or goggles,
appropriate handling and disposal of sharps and other
contaminated or clinical (infectious) waste, and use of
aseptic techniques.

35. Safe Injection Practices
Outbreaks of hepatitis B and hepatitis C infections in US ambulatory
care facilities have prompted the need to re-emphasize safe injection
practices. All health care personnel who give injections should strictly
adhere to the CDC recommendations - Safe Injection Practices which
include:
Use of a new needle and syringe every time a medication vial or IV
bag is accessed
Use of a new needle and syringe with each injection of a client
Using medication vials for one client only, whenever possible
36. Contact precautions may be needed for
germs that are spread by touching.
Everyone who enters the room who may touch the patient or
objects in the room should wear a gown and gloves.
These precautions help keep staff and visitors from spreading
the germs after touching a patient or an object the patient
has touched.
Some of the germs that contact precautions protect us from
are C.difficileand norovirus, and respiratory syncytial virus
(RSV). These germs can cause serious infection in the
intestines.
37. Summary
Know the main guidelines in each of the
clinical environments you are assigned.
Accept responsibility for minimizing
opportunities for infection transmission.
Let staff know if supplies are inadequate or
depleted.
38. Summary
Educate patients and families/visitors about clean
hands and infection transmission.
Ensure patients on precautions have same standard
of care as others:
frequency of entering the room
monitoring vital signs
