Introduction to Patient Safety:Definition
o Patient safety is a discipline in the health care sector that applies safety science methods toward the goal of achieving a trustworthy system of health care delivery. Patient safety is also an attribute of health care systems; it minimizes the incidence and impact of, and maximizes recovery from, adverse events (Emanuel et al., 2008) .
![Page 5: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/5.jpg)
Introduction to Patient Safety: Background
o Adverse medical events are widespread and preventable (Emanuel et al., 2008) .
o Much unnecessary harm is caused by health-care errors and system failures.– Ex. 1: Hospital acquired infections from
poor hand-washing.– Ex. 2: Complications from administering
the wrong medication.

Introduction to Patient Safety:
This unit of patient safety will focus on Infection Control
![Page 8: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/8.jpg)
Global Infection Problems
According to WHO (2005),o On average, 8.7% of hospital patients suffer
health care-associated infections (HAI).o In developed countries: 5-10% o In developing countries:
– Risk of HAI: 2-20 times higher– HAI may affect more than 25% of patients
o At any one time, over 1.4 million people worldwide suffer from infections acquired while in hospital.
![Page 9: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/9.jpg)
Health Care-Associated Infections (HAI)
According to WHO:o HAI is also called “nosocomial”.o HAI is defined as:
– an infection acquired in hospital by a patient who was admitted for a reason other than that infection.
– an infection occurring in a patient in a hospital or other health-care facility in whom the infection was not present or incubating at the time of admission.
![Page 10: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/10.jpg)
Impacts of Health Care-Associated Infections (HAI)
HAI can: o Increase patients’ suffering.o Lead to permanent disability.o Lead to death.o Prolong hospital stay. o Increase need for a higher level of care.o Increase the costs to patients and
hospitals.

Protect YourselfProtect Yourself Be sure you have been immunized against
Hepatitis B since it is very easy to transmit!
![Page 16: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/16.jpg)
Main Sources of Infection
o Person to person via hands of health-care providers, patients, and visitors
o Personal clothing and equipment (e.g. Stethoscopes, flashlights etc.)
o Environmental contaminationo Airborne transmissiono Hospital staff who are carriers o Rare common-source outbreaks
![Page 17: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/17.jpg)
Campaigns to Decrease Infection Rates
o WHO “Clean hands are safer hands” campaign
o Centers for Disease Control and Prevention (CDC) “prevent antimicrobial resistance” campaign in health-care settings
o Institute for Healthcare Improvement (IHI) “5 million lives” campaign– Developing country focus
![Page 18: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/18.jpg)
Main Routes for infections
o Urinary tract infections (UTI)– Catheter-associated UTIs are the most
frequent, accounting for about 35% of all HAI.
o Surgical infections: about 20% of all HAIo Bloodstream infections associated with the
use of an intravascular device: about 15% of all HAI
o Pneumonia associated with ventilators: about15% of HAI
![Page 19: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/19.jpg)

Types of Infections
![Page 20: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/20.jpg)
Four Ways to Prevent HAI
1. Maintain cleanliness of the hospital.2. Personal attention to handwashing before
and after every contact with a patient or object.
3. Use personal protective equipment whenever indicated.
4. Use and dispose of sharps safely.
![Page 21: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/21.jpg)
Prevention in Hospitals and Clinics
o Studies show infections are minimized when hospitals/clinics:– Are visibly clean;– Use increased levels of cleaning during
outbreaks;– Use hypochlorite and detergents during
outbreaks.
![Page 22: Patient Safety 1: Infection Control Yi-Hsiu Liu RN, MEd yhliu@wsu.edu Carol Allen Ph D carola@wsu.edu](https://reader030.vdocuments.us/reader030/viewer/2022032523/56649d845503460f94a6ba48/html5/thumbnails/22.jpg)
Prevention through Handwashing
